MAINTENANCE PROCEDURES
WARNING
DISCONNECT FROM POWER BEFORE CLEANING OR SERVICING.
CAUTION
Only remove approximately one infeed section of the tray carriers at one time. Removing all the
tray carriers and advancing the conveyor can cause severe damage to the machine.
LUBRICATION
The bearings used on the Model 1808 are of the type that do not require lubrication,
The conveyor main roller chains are rust resistant and an application of mineral oil or food grade chain
lube periodically is recommended. Frequency varies with each application, the machine duty cycle and
the operating environment.
WARNING
DO NOT ATTEMPT TO DO THE FOLLOWING STEP WHILE THE MACHINE IS RUNNING.
Open chains on the drive train should be coated with a good, heavy duty (FOOD CONTACT
APPROVED) chain lube. Check chains monthly for lubrication.
CHAIN TENSION
The chains should be checked for proper tension weekly.
DRIVE CHAINS
The drive chain should be taught so there is little or no backlash in the drive train. The drive chain and
its tensioner are located underneath the guard at the discharge end of the machine.
MAIN CONVEYOR CHAINS
The main conveyor chains should be tight to prevent buckling of the chains as the tray carriers come
around the bottom of the head shaft sprockets at the discharge end of the machine. If necessary, tighten
the chains using the take-up units located at the in-feed end of the machine. If
possible, try to tension
both chains the same amount so that the chains will be in alignment with each other, and the tray carriers
will run down the conveyor square to the frame.
