Service & Maintenance
To remove and replace one or more chain slats,
follow this procedure:
1. Fully loosen the chain tightener bolts on both
side tightener and center support blocks to
allow maximum slack in chain.
2. With slackened chain, skew/offset existing
damaged chain slat to allow slat holder plates
to be removed from the slat ends.
3. Place end of new slat onto existing slat holder
plate and skew/offset into position.
4. Repeat with remainder of damaged slats.
5. When finished replacing slats, fully re-tighten
the side tightener blocks and firm up center
support block against front conveyor axle.
6. Ensure front shield is closed.
7. Check chain tightness after operating and
tighten as required.

ADJUSTING CHAIN TENSION
If drag chain has slack, tightening is required:
1. Loosen the jam nut. (Both sides of machine)
2. When tightening, hold middle nut with wrench
and tighten rod end in a clockwise direction.
3. a) Start on one side and tighten the threaded
rod a few turns.
b) Repeat on opposite side of machine to evenly
tighten chain tension.
c) Repeat this procedure 2-3 times until
moderate chain tension is achieved.
d) After advancing the chain with this
procedure, measure the distance from the
round capscrew to the end of the slot. Compare
this measurement with the opposite side
measurement. Ensure the difference is less then
1/2” MAX to prevent excessive skewing of
chain slats.
4. Re-tighten jam nut securely against middle nut.
5. Repeat on other side.
6. Re-adjust center support on front conveyor axle.
1) Loosen
2) Hold
3) Tighten
(clockwise)
DRAG CHAIN
1. Occasionally check the Drag Chain for any bent
or damaged slats. It is important to straighten or
replace any damaged slats immediately.
2. The drag chain tension should be checked and
adjusted on occasion.
