DRIVE CLUTCH AND DRIVEN
CLUTCH
Keeping the drive clutch and driven
clutch clean should be the primary con-
sideration of the operator. The drive
clutch and driven clutch can be cleaned
of any drive belt accumulation using
compressed air. The sheaves can be
cleaned using a clean cloth and parts-
cleaning solvent.
CAUTION
As the belt wears, adjustment may
be necessary. To ensure proper
clutch performance, the belt posi-
tion should be adjusted by adding a
spacer (A) on each adjusting bolt
whenever the belt position reaches
1.5 mm (0.06 in.) below the edge of
the sheaves.
