WARNING: DISCONNECT PTO DRIVE SHAFT AND HYDRAULIC HOSES (RELIEVE HYDRAULIC
PRESSURE) BEFORE CLEANING, ADJUSTING, LUBRICATING OR SERVICING THIS SPREADER. FAILURE
TO HEED MAY RESULT IN SERIOUS PERSONAL INJURY OR DEATH.
FRONT DRIVE ROLLER CHAINS
There are five 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 ½" de
-
flection 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.
