6.3 Grease Points
Use a hand-held grease gun for all greasing. Pump one shot
of grease slowly into each fitting.
•
Use an SAE multi-purpose high temperature grease with
extreme pressure (EP) performance. Also acceptable is an
SAE multipurpose lithium-based grease.
•
Wipe grease fitting with a clean cloth before greasing to
avoid injecting dirt and grit.
•
If fittings do not take grease, remove and clean them
thoroughly. Replace grease fittings as necessary.

IMPORTANT! Do not over grease. Pumping more than
one shot from a grease gun into the bearings can push the
grease out of the seals. Doing that repeatedly can damage
the seals. Grease is not kept in, and dirt and moisture are
not kept out.
6.4 Conveyor Chain Tension,
Adjusting
The conveyor chain can stretch a slight amount and can require
occasional adjustment. Care must be taken the chain is not over
adjusted, as this adds pretension into the chain and reduces
chain life.
IMPORTANT! The main requirement of chain adjustment is
to remove slack from the chain (take up the clearances in
each link). It is easy to over tighten the chain, so great care
is needed!
Measure conveyor chain slack from the topside, inside the
conveyor trough. Pull the chain up at the middle and measure
dimension

. Adjust accordingly.

Loosen jam nuts (1).
2.
Turn spring tensioner nut (2) clockwise to increase chain
tension.
Make sure both sides of the conveyor are
adjusted equally.
NOTE:
It may be necessary to tap the bolt lightly to get
the spring to re-adjust the tension to the new
setting.
3.
Tighten jam nuts (1).
