Never remove chain guards while the conveyor is running.
Always replace guards after adjustments are made.
MAINTENANCE

• Conveyor Start-Up

Before conveyor is turned on, check for foreign objects that may have been
left inside conveyor during installation. These objects could cause serious
damage during start-up.
After conveyor has been turned on and is operating, check motors, reducers,
and moving parts to make sure they are working freely.
Because of the many moving parts on the conveyor, all personnel in the
area of the conveyor need to be warned that the conveyor is about to be

• Maintenance Safety Precautions

A) maintenance, such as lubrication and adjustments, shall be performed only
by qualified and trained personnel.
B) It is Important that a maintenance program be established to insure that all
conveyor components are maintained in a condition which does not constitute a
hazard to personnel.
C) When a conveyor is stopped for maintenance purposes, starting devices
or powered accessories shall be locked or tagged out in accordance with a
formalized procedure designed to protect all person or groups involved with the
conveyor against an unexpected start.
d) Replace all safety devices and guards before starting equipment for normal
operation.
E) Whenever practical, dO NOT lubricate conveyors while they are in motion.
Only trained personnel who are aware of the hazard of the conveyor in motion
shall be allowed to lubricate.
SAfETY GUARdS
maintain all guards and safety devices IN POSITION and IN SAfE REPAIR.
WARNING SIGNS
maintain all warning signs in a legible condition and obey all warnings. See
Safety manual for examples of warning signs.

• Lubrication

The drive chain is pre-lubricated from the manufacturer by a hot dipping pro-
cess that ensures total lubrication of all components. However, continued
proper lubrication will greatly extend the useful life of every drive chain.
drive Chain lubrication serves several purposes including:
• Protecting against wear of the pin-bushing joint
• Lubricating chain-sprocket contact surfaces
• Preventing rust or corrosion
for normal operating environments, lubricate every 2080 hours of operation
or every 6 months, whichever comes first. Lubricate with a good grade of
petroleum or synthetic oil (i.e., Shell Rotella or mobil 1). for best results,
always use a brush to generously lubricate the chain. The proper viscos-
ity of lubricant greatly affects its ability to flow into the internal areas of the

chain. Refer to the table below for the proper viscosity of lubricant for your
application.
Ambient Temperature
The drive chain's lubrication requirement is greatly affected by the operat-
ing conditions. for harsh conditions such as damp environments, dusty
environments, excessive speeds, or elevated temperatures, it is best to
lubricate more frequently. It may be best, under these conditions, to develop
a custom lubrication schedule for your specific application. A custom lubri-
cation schedule may be developed by inspecting the drive chain on regular
time intervals for sufficient lubrication. Once the time interval is determined
at which the chain is not sufficiently lubricated, lubricate it and schedule the
future lubrication intervals accordingly.
