Listen to everything for unusual noises or vibration

Visually inspect to see that conveyor sections are clear and free of debris

Check to see that all safety guards are in place

WARNING: Prohibit walking or riding on conveyor by anyone. Care should be taken when servicing any conveyor to prevent accidental injury. All moving parts are potentially dangerous.

Check for proper PSI on air regulators.

Check air filter bowls for accumulated water.

Air Systems: The best preventive maintenance for any air operated device is clean air. Dirty air will make pneumatic devices sticky, and they will not operate properly.

Monitor filter / regulator bowl drain every week.

To manually drain the bowl, push the push button at the bottom of the bowl. Let all accumulated liquid drain until you hear air escaping.

WARNING: Do not perform maintenance on the conveyor until the start-up controls, including motor safety switches, are locked out and cannot be turned by any person other than the one performing the maintenance.

If more than one member of a crew is working on the conveyor, EACH CREW MEMBER MUST HAVE A LOCK ON THE POWER LOCK OUT. The air pressure must be turned off to the work area. All pneumatic devices must be de-energized to prevent accidental cycling of the device.

Check the loosened parts have been retightened and all guards reinstalled.

Warning: This procedure requires trained personnel with PPE!

Measure the distance of the chain tension 2 m (6’ 6”) in front of the return pulley

Measure the lift of the aluminum slat causing the shoe to rise about 3 mm (1/8”)

Measure the lift of the succeeding running wheel 1mm (1/32”) ± 0.2 mm (.030”-.040”) from the surface of the guide

Does the succeeding running wheel lift from the surface of the guide?

If the succeeding running wheel does not lift from the surface of the guide, the tension must be increased.

Sign off on the chain tension check

Warning: Ensure the engine is off and cool before starting the procedure

Remove tension from timing belt

Install new timing belt in reverse order

Sign off on the timing belt replacement

Warning: This procedure requires trained personnel with PPE!

Is the tension pulley square within the conveyor frame?

If not, adjust the tension pulley to be square within the conveyor frame.

Is the tension pulley tensioned evenly on both sides?

If not, adjust the tension pulley to be tensioned evenly on both sides.

If not, loosen the tension pulley by turning the nut counterclockwise and release all tension of the belt.

Enter the distance between the two lines marked on the belt.

Tension the conveyor belt by turning the nut clockwise until a belt tension of about 0.3% (corresponds to 1003mm (39-1/2”) is achieved between both lines.
