WARNING
: SHUTOFF AND LOCKOUT POWER BEFORE CLEANING, ADJUSTING, LUBRICATING
OR SERVICING THIS SPREADER. FAILURE TO HEED MAY RESULT IN SERIOUS PERSONAL INJURY OR
DEATH.
7.1. FRONT DRIVE ROLLER CHAINS
There are six roller chain drives located at the front of the spreader. Regularly check that all tensioning springs
are in serviceable condition for automatic roller chain tightening. Manually adjust spring tensioners (as needed)
by turning double locknuts on all tensioning bolt/idler assemblies. Proper roller chain tension is when 1/4" to 1/2"
deflection occurs on the slack side of the chain. Regularly re-check all roller chain tensions. Keep all roller
chains tight at all times! For clarity purposes, the following illustrations detail each roller chain reduction
separately.
NOTE:
The side bars of the roller chains will wear into the idler nylon rollers up to the rollers of the roller chain
forming grooves. These grooves will serve as a guide when the roller chain loosens due to normal use. From
this point on, after tightening, the idler nylon rollers should run for hundreds of hours without any noticeable
wear.
The first chain drive (PTO input shaft to the large RH
top sprocket, Figure 6) is automatically tensioned by a
spring loaded idler nylon roller. The extension spring
should extend 2” from its neutral 5” total length.
Manual adjustment for the automatic tensioning idler,
nylon roller assembly is located at the left rear of the
spreader’s front bearing mounting plate.

The second chain drive (large RH top sprocket to the
large LH top sprocket, Figure 7) is automatically
tensioned by a spring loaded idler nylon roller. The
extension spring should extend 2” from its neutral 5"
total length.
Manual adjustment for the automatic tensioning idler,
nylon roller assembly is located at the left rear of the
spreader’s front bearing mounting plate.
