Maintenance
To aid in the high reliability of the shrink tunnel, inspect the machine regularly and
perform maintenance as required. Disconnect electrical power before making any
repairs. Be very careful when servicing or adjusting this equipment. If in doubt, stop and
obtain qualified help before proceeding.
CAUTION! When replacing motors, if the tunnel chamber is below 160
degrees, the heater bank switch may need to be turned on to
apply power to motors for testing.
Preventative Maintenance

Lubricate roller chains every 60 hours with a high temperature oil. Use a brush to
apply lubricant while running the conveyor slowly.

Inspect the rollers of the conveyor regularly to ensure that no scrap pieces of film
are wrapped around the rollers to cause sticking packages.
To Clean Rollers:
- Run the conveyor until the affected rollers are inside the heat chamber to heat
the film residue and soften the film so it will clean easier.
- Advance and then stop the conveyor so the heated rollers are out of the
chamber and accessible for cleaning.
CAUTION! Make sure the conveyor is stopped before putting your fingers
or anything else in the conveyor area.
- Remove film residue. If necessary, use a dull blunt-edged tool. Do not use
any sharp instruments, as nicking silicone may result in damage that requires
replacing the roller covering.
Perform the following maintenance checks each month.

Check and clean the intake screens.

On dead roller tunnels, clean and lubricate the conveyor chains. Check the chains
and adjust as needed.

Check the condition of the silicone covering on the rollers. Repair or replace as
necessary.

On mesh belt conveyors, check the mesh for material stuck in or on the belt.
Check and adjust the belt tension as needed.

Check and clean the motor-to-conveyor drive chain. Adjust tension as needed.
