Cross Bar chain tension
Chains are responsible for parallel movement of the cross seal bar.
To check tension and adjust if needed:
The chain (a) displacement is approximately 0.5 inches (12 mm) on center
if light pressure is applied to the chain.
The adjusting tensioners (c) are located at the upper ends of the chain
system. Use a 9/16 wrench to loosen the two mounting bolts and adjust the
tension bolt. Retighten the mounting bolts.
Note:
Tension should be check every three months.
Replacing silicone rubber padding:
WARNING:
Wait until the heat sealing bar has cooled enough (approx. 3 hours) before servicing seal
bars or the areas near the bars. If maintenance on the machine is absolutely necessary before sealing
bars have had a chance to cool down, the person performing the maintenance must use safety equipment
approved by OSHA or local law to protect against burns.
With seal bar in the up position remove non-stick tape. Next remove
the damaged silicone padding completely. Clean glue off with
mineral spirits.
(DO NOT LOOSEN ANY OF THE SCREWS
BENEATH THE SILICONE PADDING AS THIS WILL
DISRUPT THE SEAL BAR LOWER RAIL ALIGNMENT!)
Glue new padding to the rail. Secure PTFE tape and see shimming
