7.4 Clutch Inspection
Inspect clutch between each use.
NOTICE
Prevent clutch damage.
Engine must be running at operating
speed (3600 rpm) when grinding a
stump.
1. Park grinder on a level surface.
2. Shut off engine.
3.
Inspect clutch bearing seal area (A). Grease on outside
of seal indicates excessive heat. Discoloration in areas
(B) also indicates excessive heat. Excessive heat is a re
-
sult of clutch slippage. This is normally due to grinding a
stump at less that operating speed. Verify engine throttle
is properly adjusted so engine runs at operating speed
(3600 rpm)
when safety bar is tight against handle.
4. Inspect pulley grooves. Wear in the bottom of pulley
grooves (C) indicates that belt is worn out and must be
replaced. Excessive belt wear is a result of belt slippage.
This is normally due to belt not being tight enough and will
damage the pulley as it must run cool to work properly.
