Tracking & Tensioning Conveyor Belt - Grizzly G1066R Owner's Manual

Tracking & Tensioning
Conveyor Belt
Working around moving conveyor and parts
presents pinch/entanglement hazards that
can cause personal injury. Use extreme
care to keep hands clear of in-running pinch
points while adjusting tracking bolts when
machine is running. Roll up sleeves and do
not wear gloves or other apparel that could
become entangled in moving parts.
The conveyor belt must track straight. If the belt
tracks to either side, then the tracking must be
corrected or the conveyor belt will become dam-
aged and have to be replaced. The tracking was
properly set at the factory, but eventually, wear
may cause it to track unevenly.
Tracking the conveyor belt is a balancing process
that takes patience and some trial and error.
Usually, you must over-tighten the loose side to
make the belt move to center of the rollers, then
loosen that same side to make the conveyor belt
stay in position. If the tracking bolt is over-adjust-
ed, the process will need to be repeated until the
conveyor belt stays centered on the rollers.
The conveyor belt will stretch when new and will
eventually need to be tensioned. This is most
obvious if the conveyor belt starts slipping on the
rollers.
When adjusting conveyor belt tension, focus on
adjusting the tension bolts in even increments.
Adjusting one side more than the other will cause
tracking problems, which will require additional
adjustments to get the conveyor belt tracking cor-
rectly again.
Note: Whenever possible, make tracking adjust-
ments to infeed end of conveyor to avoid needing
to make adjustments to table elevation chain.
