KL15769 Cannular Compact Semi-Auto Canning Machine | Troubleshooting
Cannular cuts out in use
Power Supply tripping - bearings
Check that the rollers and table bearings spin freely. Too much restriction can cause the power supply to trip
Power Supply tripping - table hieght
Check the table hieght. If the can is pushed against the chuck too hard this can overload the power supply in use.
Faulty Power Supply
Test DC output with multimeter. Replace Power Supply if faulty
Cannular does not stop after complete operation
Faulty Relay or Microswitch
If the Cannular continues running after the both operations are complete it could either be a faulty relay or a faulty micro switch. There is no real way of checking which it might be other than replacing parts.
The relay is located at the back of the unit under the cover near the anderson plug and to access the micro switch you will need to take the blue cog wheel out. The black lobe activates the micro switch after each rotation.
Cannular does not return to correct start position
Microswitch requires adjustment
Refer to
Can buckles when operation begins
Table height to high
Cannular Table not concentric
KL15769 Cannular Compact Semi-Auto Canning Machine |Setup
Aluminium cans should only be used to store beer. They have not been tested with other beverages such as wine or spirits.
Do not operate the cannular without first confirming the cannular is in specification according to the specific chuck used. Confirm the rollers do not contact the chuck prior to operation of the machine by manually turning the chuck or flywheel through a full cycle.
Ensure the cannular is unplugged before placing any body part near any moving parts or when manually rotating the motor or the chuck. There is a risk of serious injury or damage to the motor if the cannular is plugged in while making any adjustments.
Avoid contact of any electrical components with liquid.
Immediately upon unpacking the Cannular inspect the unit for any signs of damage and do not operate the Cannular if any damage is observed.
The Cannular has been designed to suit cans available from KegLand and comes standard with a B64 chuck which is compatible with cans available from KegLand. It is possible to setup the Cannular to seam a wide range of can heights and diameters by setting up the machine differently. For different can sizes you will need to adjust the rollers and change the chuck to suit the specific non-KegLand can end.
If you are using cans from a different supplier we do not offer dies or information about machine setup for cans that we do not sell. You will need specification and machine setup information from your can supplier.
A 24V Power supply rated to a minimum of 12.5 amps with a standard Anderson Plug is required to run the Cannular. If you do not have a power supply they are stocked on our website. Only the un-wired 20A power supply or 24V 12.5A DC power supply should be used with the Semi-Auto Cannular.

The Cannular is a portable light weight canning machine. The feet are designed to grip the bench top; however, if you are planning to use the canning machine for an extended period of time in the same position we recommend clamping or mounting the machine to your bench top.
The Cannular can be mounted to a bench by drilling a screw through the mounting brackets on the bottom of the Cannular.
Your Cannular is calibrated and set up at the factory to seam KegLand 500 mL B64 cans (, and ). Due to transit it may have shifted out of specification. Calibration is an essential requirement of all canning setups and must be checked before seaming. All canning machnes require periodic calibration to ensure consistency and pressure tight seaming.
Before Calibration perform the following start up procedure/checks.
Remove the cover of the Cannular using a 4mm Allen Keyto improve access to the chuck, rollers and flywheel.
With the Cannular unplugged from the power supply, turn the flywheel or the chuck clockwise until both rollers have completed their full rotation to ensure that neither of the rollers contact the chuck at any point. If either roller contacts the chuck then adjust the position of the rollers according to the measurements in .
Important: Under no circumstances allow the rollers to come into contact with the chuck. Both chuck and rollers are hardened steel and require high tolerances; contact will damage them.
1st & 2nd Operation Rollers in start position - furthest from chuck
1st Operation Roller in operation position - closest to chuck
2nd Operation Roller in operation position - closest to chuck
Both operations complete - both rollers back to start position
When the power (On/Off) switch is not depressed, pressing the operation (momentary) switch will nudge the motor/rollers — useful for adjustments.
When the power (On/Off) switch is depressed, pressing the operation (momentary) switch will run the motor through its full rotation. Ensure the Cannular is in specification before running a full cycle.
The Cannular is shipped with a B64 chuck for B64 can ends. All KegLand aluminium cans are suited to a B64 chuck.. For non-KegLand can ends you may need a different chuck and setup information from your can supplier. VISY or CDLE/CDL can ends require a KL14670 .
To change the chuck:
Unscrew the two grub nuts using a 3 mm Allen key and pull downwards to remove the chuck from the drive shaft (may require force).
Push the required chuck as far up onto the drive shaft as it will go and fasten with the two grub nuts. Tighten grub screws securely.
KL15769 Cannular Compact Semi-Auto Canning Machine | Other Adjustments
The can must be raised concentrically against the chuck for a good seam. If the can collides with the top or is not concentric, adjust the table.
Note: Poor concentricity can cause buckling or leaking, particularly on the second operation. If your can is not raised up against the chuck concentrically you may notice your seam leaking and/or the can buckling, particularly on the second operation.
If the buckling occurs on the second operation then please check your can is being raised straight up and completely concentric with the chuck.
If the table is very close to concentric and only needs small adjusments, use the following process.
Undo (turn counter-clockwise) the coupling nut on the turn table using an Allen key.
Use two fingers to move the turn table slightly in the desired direction while retightening (turn clockwise) the coupling nut.
Check the can now lifts concentrically.
Unplug the power and tip the machine on its back (see above right)
Use a 5 mm Allen key to undo the three bolts securing the turn table to the base
The Cannular is setup for seaming B64 ends out of the box.
In order to seam VISY (CDL/CDLE) ends you will need to purchase and install a KL14670
The Cannular is shipped with a B64 chuck for B64 can ends. All KegLand aluminium cans are suited to a B64 chuck.. For non-KegLand can ends you may need a different chuck and setup information from your can supplier. VISY or CDLE/CDL can ends require a KL14670
To change the chuck:
Unscrew the two grub nuts using a 3 mm Allen key and pull downwards to remove the chuck from the drive shaft (may require force)
Push the required chuck as far up onto the drive shaft as it will go and fasten with the two grub nuts. Tighten grub screws securely
Note: B64 chuck used in this example. The process for installing a VISY chuck is identical
Once the chuck has been installed the rollers will need to be .
Note: The roller position varies between Cannular models.
KL10757 - 1st Operation Roller on the left, 2nd Operation Roller on the right
KL15769 - 1st Operation on the right, 2nd Operation on the left
For a calibration guide for the Manual Cannular please refer to the . The rollers must be calibrated to the VISY chuck after the new chuck is installed otherwise a pressure tight seam will not be achieved.
Both rollers have detented positions allowing 360° rotation around the drive shaft to accommodate wider cans (e.g., tin cans).
For aluminium cans: set the detent so the roller is at its closest detent position to the chuck (closest in y-axis). Note: Out of the box, all Cannular models are setup with the rollers in position for 202 diameter aluminium cans
For larger tin cans: set the detent so the roller is at its furthest detent position from the chuck.
Note: Rollers shown removed for clarity. Once set and tightened they generally do not need further adjustment.
If the Cannular does not automatically return to the correct start position (with the rollers both in the furthest position from the chuck) then the microswitch position may need to be adjusted. This can be remedied by following these steps.
Nudge the cannular into the correct starting position where the 2nd operation roller has finished its movement and the 1st op roller is at its furthest position to the chuck. The rollers can be nudged into the correct position either by turning the blue cog by hand or by pressing the momentary switch when the on/off switch is in the off position. Refer to
Using a 4mm Allen Key, rremove the blue cog on the top of the unit by undoing the bolt which holds it in position
Using a 3mm Allen Key, undo the grub screw on the following piece on the drive shaft
Rotate this piece while holding the drive shaft in position (by using the Allen Key as a lever) until it is positioned against the microswitch as shown and then tighten the grub screw in position
Now reassemble the Cannular. This will correct the starting position issue
Before raising the table ensure that the rollers are at their starting position: set the power on/off switch to ON (depressed), then press the operation button. The Cannular will run through its full operation and return to its starting position.
Raise the table and ensure the can and can lid are held firmly into the chuck.
Press the operation button (with the power on/off switch in the on position).
After the Cannular has run through its full operation and has returned to its resting position, lower the table, remove the can and inspect the seam for leaks.
If the seam leaks then calibrate the Cannular according to the calibration instructions.
We recommend checking seam specifications every 50,000 cans or once a year to ensure tolerances remain acceptable.
Power supplies are sold separately.
Re-tighten the three bolts with the Allen key once satisfied.

KL15769 Cannular Compact Semi-Auto Canning Machine | Seaming Troubleshooting
Most of the time, if there are seaming issues with cans after the seaming operation, the issue is incorrect calibration.
Seaming issues encompass any leaks from the seam of the can or end. Inconsisstent seaming also indicates that the calibration of the rollers to the chuck is not 100% accurate.
Canning is a very precise operation, and care must be taken to ensure that all parts (table, chuck and rollers) are calibrated correctly. Failure to calibrate to sepcification will result in inconsistent seams and leak issues.
Remember: if you are having difficulties getting consistent, hermetic double seams, then the calibration of the Cannular is likely not in spec.
Remember: to check calibration of a Cannular to achieve a hermetic double seam, use calipers to measure the following:
Actual overlap (>0.4mm)
2nd Op seam thickness (1.2-1.3mm)
Some common seaming issues are listed below. it is not possible to cover all possible seaming issues.
It is also helpful to be familiar with the components of the seam before troubleshooting
First, follow to help determine the seaming issue by seaming and cutting two cans.
This will help narrow the seaming issue down.
Seaming issues tend to fall into three broad categories - overlap issues, seam size issues, and other issues.
If the overlap is insufficient as determined after following , try to see where exactly the issue - short or long body hook, short or long cover hook etc as this can help isolate the issue and make correction easier. However, in practice it can be quite difficult to accurately asses the exact cause of overlap issues visually without specialised tools.
Getting an overlap of at least 0.4mm is critical to obtaining a hermetic double seam. Other seam issues are generally less critical and easier to correct once the overlap is correct. The overlap is almost entirely determined by correct 1st Operation clibration.
If the finished seam has good overlap but is too long or too short then this will likely casue leaking issues. Provided there is good overlap (>0.4mm) after both first and second operations then the likely problem is the 2nd Operation Roller is out of spec.
In addition, if the overlap is good after the 1st Operation, but too small after the 2nd Operation, this is likely a 2nd Operation calibration issue
To check the specs of the 2nd operation please follow
To adjust the 2nd Operation Roller relative to the chuck refer to
Always ensure that there is sufficient overlap (>0.4mm) after the 1st Operation before proceeding with further troubleshhoting of seam issues. Insufficient overlap is the most common cause of seaming issues. A hermetic double seam cannot be achieved without suffiecient overlap. Once there is good overlap after the 1st operation, refer below for further troubleshooting diagnostics.
KL15769 Cannular Compact Semi-Auto Canning Machine | Calibration Overview
Use this page after you’ve completed initial checks and a test seam.
Back to:
In a large commercial operation there are several critical parameters commonly checked in commercial settings include 2nd operation seam thickness, seam gap, actual overlap, body hook butting and tightness.
However, when calibrating a Cannular, very close to the same can seaming confidence can be acheived by checking three easy to measure parameters:
Actual overlap
KL15769 Cannular Compact Semi-Auto Canning Machine | Calibration & Seam Checking
Ensure the correct chuck for your can ends is installed and tightened - if seaming B64 cans such as all aluminium cans supplied by KegLand then this will already be installed. Unplug the machine before adjusting rollers. The top cover can remain on but removing it may aid access. It is receommended to remove the cover when calibrating. The cover is held in place with 4mm Allen Bolts.
Remember: to check calibration of a Cannular to acheive a hermetic double seam, use calipers to measure the following after the 1st operation (overlap) and both operations (seam width and length):
Actual overlap (>0.4mm)
Long Body Hook causing insufficient overlap
2ns Operation Roller too close in x-axis resulting in over tight seam Table height out of spec - Possibly the can is too snug against the chuck
Short Body Hook causing insufficient overlap
1st Operation Roller out of spec - check y-axis Table height out of spec - ensure can is snug against chuck
Finished seam too tall (>2.4mm)
2nd Operation Roller too close to chuck in y-axis
Adjust 2nd Operation Roller further from the chuck in the y-axis (1.35 mm ± 0.05 mm)
Finished seam too short (<2.3mm)
2nd Operation Roller too far from chuck in x-axis
Adjust 2nd Operation Roller closer to the chuck in the y-axis (1.35 mm ± 0.05 mm)
Overlap too small after 2nd Operation (if overlap >0.4mm after 1st Operation)
2nd Operation Roller too close to chuck in y-axis
Adjust 2nd Operation Roller further from the chuck in the y-axis (1.35 mm ± 0.05 mm)
Horizontal crease in circumference of seam
2nd Operation Roller too close to chuck in x-axis
Adjust 2nd Operation Roller away from the chuck in the x-axis (0.3 mm ± 0.1 mm)
Horizontal crease in circumference of seam
2nd Operation Roller too far from chuck in x-axis
Adjust 2nd Operation Roller closer to the chuck in the y-axis (1.35 mm ± 0.05 mm)
False Seam - no overlap at all
This will normally be detected when testing after 1st Operation only. If the body hook is under the cover hook with no overlap it is a false seam. 1: Table height out of spec - ensure can is snug against chuck 2: 1st operation roller y-axis too high or x-axis too far from chuck, or both
Overlap is shorter after 2nd Operation
If the overlap is good (>0.4mm) after the 1st Operation, but becomes shorter after the 2nd Operation, this is a Sprung Seam. 1. The 2nd Operation is too tight - check x-axis against 2. The 2nd Operation Roller is too low- check y-axis against
Dimples in bottom edge of seam
Rollers or chuck may be damaged - inspect and replace if required Can or end may have been damaged before seaming operation - test with a new can and end Table height out of spec - Possibly the can is too snug against the chuck
Sharp Seam
1st Operation Roller too close to chuck in x-axis 2nd Operation Roller too close to chuck in x-axis
Overlap in spec (>0.4mm) but inconsistent or no hermetic seam
2nd Operation Roller out of spec
and adjust 2nd Operation accordingly
Overlap in spec but inconsistent or no pressure seam
Table Height not correct
Table height out of spec -
Some cans leak after a run
Calibration not in spec
Check specs using . Adjust accordingly
Some cans leak after a run
Table Height not correct
Table height out of spec -
Cannular in spec (according to ) but seaming is inconsistent
Rollers or chuck damaged
Inspect rollers and chuck for damage. Replace if damaged
2nd Op seam length (2.3-2.4mm)
These three measurements are the best way to determine if the Cannular is correctly calibrated.
Short Overlap - cannot determine exact issue (cover hook, body hook, etc)
If the overlap is less than 0.4mm first check table hieght - ensure the can is snug against the chuck with no possibility of buckling. Next, check the 1st Operation specs - this is the most likely reason for a short overlap
Short Cover Hook causing insufficient overlap
1st Operation Roller out of spec - check y-axis Table height out of spec - ensure can is snug against chuck
Finished seam too narrow (>1.3mm)
2nd Operation Roller too close to chuck in x-axis
Adjust 2nd Operation Roller away from the chuck in the x-axis (0.3 mm ± 0.1 mm)
Finished seam too wide (<1.2mm)
2nd Operation Roller too far from chuck in x-axis
Adjust 2nd Operation Roller closer to the chuck in the x-axis (0.3 mm ± 0.1 mm)
Irregular, V shaped ripples in the finished seam
1: Table height out of spec - ensure can is snug against chuck 2: Rollers or chuck may be damaged - inspect and replace if required 3: 1st Operation Roller out of spec - check overlap after 1st Op only
Body flange protrudes past seam in localised area of seam
Can or end may have been damaged before seaming operation - test with a new can and end One or both Operation Rollers out of spec - check measurements aginst this guide Table may not be concentric against chuck - inspect visually and adjust table
2nd Op seam thickness
2nd Op seam length
Actual Overlap (1st operation) and 2nd Operation seam thickness are the most important parameters
To achieve a good seam, the Cannular must have the following steps correctly calibrated.
Table Height Adjustment. This determines that the can end is snug enough against the chuck for the rollers to operate within very right parameters.
1st operation: This is the most important operation. The 1st Operation Roller takes the end curl and the can flange and begins the forming process. This causes the can end to curl under the can flange, creating an overlap. This overlap is vital to the seaming process. The 1st Operation Roller specification governs the amount of overlap.
2nd operation: compresses and finishes the seam formed by the 1st operation. The 2nd Operation Roller governs the size and fit of the seam after the overlap is created by the 1st operation.
Both rollers must be correctly positioned; incorrect 2nd op positioning can still cause leaks even if 1st op is correct.
When calibrating any canning machine including Cannulars, feeler gauges may be used to check the gaps in the x and y axis between the 1st and 2nd operation rollers. However, the gaps can be quite difficult to measure accurately. However, using calipers it is quite simple to measure the seam after the first and the second operations.
In the above illustration, we can see how the 1st Operation Roller forms the overlap. The 2nd Operation Roller then compresses the seam.
The below images provide a pictorial overview of each operation. This can be helpful when troubleshooting to determine what adjustments need to be made to the roller(s)
1st Operation - forming the overlap
2nd Operation - closing the seam
This determines whether there is sufficient overlap between body hook and cover hook.
Follow these practical steps:
Using Can B, take the average of four measurements around the circumference with calipers. The average should be between 1.2–1.3 mm
If smaller: insufficient actual overlap or 2nd op roller too close to the chuck — re-examine overlap and 2nd op gaps
If larger: 2nd op roller may be incorrectly positioned (too far or too close to the chuck), and springback can increase seam thickness
Using calipers measure seam length on Can B. Ideal: about 2.3–2.4 mm
A tight seal can still be achieved with seam length up to 3.3 mm if actual overlap remains sufficient
Short seam length indicates 1st op roller too close to the chuck or 2nd op roller too far in the y-direction
Remember: to check calibration of a Cannular to acheive a hermetic double seam, use calipers to measure the following:
Actual overlap (>0.4mm)
2nd Op seam thickness (1.2-1.3mm)
2nd Op seam length (2.3-2.4mm)
These three measurements are the best way to determine if the Cannular is correctly calibrated.
These three measurements are the best way to determine if the Cannular is correctly calibrated.
The 1st and 2nd operation rollers of the Cannular must be calibrated to a high degree of accuracy to ensure a good, pressure tight double seam
The measurements of the overlap (after 1st Operation) and the completed seam (after 1st and 2nd Operation) are the best way to determine if the Cannular is calibrated correctly and producing a heermetic double seam.
2nd Op seam length (2.3-2.4mm)
For more information and troubleshooting please refer to Calibration Overview
Warning: Do NOT install any table or table spacer other than the table provided with the KL17879 Semi-Automatic Cannular). A table spacer is not required and should never be used on this model.
Adjusting the table height to suit the cans to be seamed should be performed before calibrating the rollers.
The table height should be adjusted so that the can and end are securely engaged against the chuck when the table is lifted and locked in place. If the can buckles, it is too high. If the can can be moved against the chuck, it is too low
Using an Allen key or steel rod as a lever in the coupling nut, undo the coupling nut on the base of the turn table support by turning anti-clockwise (left to right). Hold the table lever to prevent rotation.
Turn the table support anti-clockwise to raise and clockwise to lower the turn table support.
Loosening coupling nut
Tightening coupling nut
Gradually raise the table until firm pressure holds the can against the chuck. The can should be held firmly but not buckle. Tighten the coupling nut clockwise (right to left) firmly using an Allen key as a lever (above).
Note: The table must be concentric to the chuck in order to acheive a good double seam. If the table requires adjsutment please refer to Table Position Alignment. Typically this is not required - it is extremely rare for the Cannular Table to not be concentric to the chuck out of the box.
Once the Table Height has been adjusted and is concentric, then the rollers must be calibrated to the chuck in order to acheive a seam. For a good, hermetic double seam the tolerances are quite tight.
To check calibration it is best to measure the overlap and finished seam as it can be quite difficult to measure gaps accurately using KL13420 feeler gauges
Thus, calibration is performed using feeler gauges to set the gaps between the rollers and the chuck. Seam measurements are used to determine that these have been set correctly.
The below calibration procedure applies to both B64 and VISY chucks. Note that correct calibration is determined by actual seam measurements.
The right hand roller performs the 1st operation.
Use a KL13420 feeler gauge set for precision.
Always adjust the Y axis/gap first. The X axis/gap will change when the y axis is adjusted
Unplug the power from the machine
Turn the chuck clockwise until the 1st operation roller is at its closest position to the chuck. NEVER turn the chuck anticlockwise (risk motor damage)
Note: It is also possible to use the Momentary button to 'nudge' the rollers into place. First, turn the Power Switch off. Then you can use the front, Momentary Switch to nudge the roller until it is in the closest postion to the chuck for calibration
Using a 14 mm spanner or socket, loosen the y-axis adjustment nut as shown
Slide the roller vertically along the drive shaft to set gap Y to 0.05 mm. The 1st operation roller should be as close as possible to the chuck in the y-axis without touching
Measure gap Y from the flat face of the roller to the top of the chuck
You may need to increase the x-gap slightly so the curved face is further from the chuck to measure from the flat face
Tighten the Y-Axis Adjustment Nut firmly once gap Y is correct
With the roller at its closest position to the chuck, loosen the X-Axis Adjustment Nut with a 14 mm spanner or socket
Adjust the roller so gap X between the chuck and the 1st op roller is 0.6 mm ± 0.1 mm. Ensure the feeler gauge is flush with the face of the chuck and placed at the same angle as the chuck when taking the measurement
Tighten the x-axis adjustment nut firmly once the correct gap X is achieved
Note: gap X may change as you tighten the x-axis adjustment nut. To prevent this, tighten the nut from the side of the machine to avoid torquing the arm holding the roller
Note: The X-Axis Adjustment Nut may not provide fine enough adjustment during calibration. For finer adjustments, the detented roller can be used.
Once the 1st Operation Roller has been calibrated, check the actual overlap to ensure it is accurate
The required Gap Alignment for the 1st Operation Roller:
Gap Y for 1st op: 0.05 mm ± 0.05 mm (as close as possible without touching)
Gap X for 1st op: 0.6 mm ± 0.1 mm
The left roller performs the 2nd operation. Use the same process as for the 1st Operation Roller to adjust the 2nd Operation Roller.
The required Gap Alignment for the 2nd Operation Roller:
Gap Y for 2nd op: 1.35 mm ± 0.05 mm
Gap X for 2nd op: 0.3 mm ± 0.1 mm
Note: The X-Axis Adjustment Nut may not provide fine enough adjustment during calibration. For finer adjustments, the detented roller can be used.
Use the x-axis adjustment nut for large movements. For fine adjustments take advantage of the detented rollers and the roller hex socket.
Loosen the y-axis adjustment nut just enough that the roller is still held in position in the y-axis
Insert a 4 mm Allen key into the hex socket on the underside of the roller and turn counterclockwise slightly to loosen. Do not loosen too far or the roller may fall off
As the hex socket loosens the roller will rotate around the drive shaft and move closer or further from the chuck depending on the shaft position. If the roller does not move, loosen the y-axis nut further
Once the roller is in the correct x-position, confirm gap Y, tighten the y-axis adjustment nut to lock the roller, then tighten the hex socket on the bottom of the roller
Ensure the Allen key bolts on the underside of the rollers are tight, then rotate the rollers by finger to confirm they spin freely without much resistance.
Important: After adjusting, manually turn the chuck clockwise through a full rotation to ensure the rollers never contact the chuck.
After positioning the rollers, assess the actual overlap, seam width and seam height using the Checking Seam Quality Guide) to confirm seam quality and that parameters are within allowable ranges.
These three measurements are the best way to determine if the Cannular is correctly calibrated.
Once both rollers have been bought into specification, test the seam using the Guide. The required gaps are a guide to getting the rollers into caibration. However, the actual measurements of the seam after the 1st and 2nd Operations are are more reliable method of determining if the rollers are in spec or not. This is largely because it can be quite difficult to accurately assess roller/chuck gaps using feeler gauges.
Very long seam indicates 2nd op roller too close to the chuck in the y-direction; this can cause overlap separation and leaks
Cut away a wedge from the top of the can using an angle grinder (1 mm cutting disk recommended) or a hacksaw if unavailable
Use a utility knife to scrape the cut clean. Fine sandpaper can also be used. This will help assess the overlap
Examine the overlap (distance X between the bottom of the body hook and top of the cover hook)
Ideally actual overlap after operation 1 should be more than 0.4 mm
If less than 0.4 mm, verify the 1st operation roller position and re-adjust as necessary
Examine final overlap after both operations. This is harder to see; gently pry the seam open slightly with a sharp object to visualize start and finish of the hooks (without significant dimensional change)
Minimum requirement: at least 0.4 mm; over 1 mm is ideal
If first operation overlap is good but final overlap is poor, the 2nd operation roller position may be incorrect — re-evaluate both rollers
Please take appropriate safety precautions when using power tools.
