Routine Maintenance
Disconnect power supply and lock out before removing any guards, attempting any
maintenance, trouble shooting, or making adjustments.
Warning!
Ensure all moving parts have completely stopped before opening shields or reaching
into conveyor.
Belt Care

Lubrication - Periodically oil the hinged steel belt to keep the belt components moving freely
and to reduce belt drag. This will minimize wear on the belt components, especially if the
belt is operating in dry conditions.

Belt Tension - Check for correct belt tension at least monthly (more frequently if the
conveyor carries heavy loads or runs continuously) or after any occurrence of jamming. Use
the following points as a guide to the correct tension.
o
Too tight a belt will usually pulsate as it moves through the frame.
o
Too tight a belt will cause a high amperage draw on the motor.
Note: Excess tension causes increased wear and reduced belt life.
o
Too loose a belt will buckle as it leaves the in-feed sprockets and as it contacts the
drive sprockets. This condition often causes jamming and can easily damage the
belt.
Motors

Cleaning - All motors should be kept free of dirt and grease accumulations. Open motors
should be periodically vacuumed to remove dust and dirt from the windings.

Ventilation - For best results motors should be operated in an area where adequate
ventilation is available.

Temperature - Most of the current smooth body, T.E.N.V. and T.E.F.C. motors run hot to
the touch. As long as maximum ambient temperatures are not exceeded and the amperage
draw is within the allowable range there should not be a problem.
Note: The temperature and amperage limits can be found on the motor nameplate.

Lubrication - Most electric motors are lubricated for life, and under normal operating
conditions require no more lubrication. Under severe conditions where additional
lubrication is required, use the following chart as a guide. See Fig. 11.
