1)Position the SURFACE GRINDER on a suitable work surface with the
2)Remove the rubber latches and slide the belt guard away from the engine/electric motor until it clears the catch mechanism. Remove the belt guard from the main frame. Clean the inside of the belt guard with an appropriate solvent.
Check for signs of wear and damage. Secure in a proper storage area.
CAUTION
Observe all applicable safety precautions for the solvent.

c)Keep the belts as clean and free of foreign material as possible. Do not use belt dressing
6)The centrifugal clutch assembly utilized on both the gasoline engine powered and Propane converted SURFACE GRINDERs is designed to deliver an extended service while requiring minimal service. However, long term use of the SURFACE GRINDER can allow the accumulation of fine dusts and powders within the clutch assembly. These dusts and powders can dramatically reduce the capacity of the the
clutch drum bearing, resulting in the following operational characteristics:
a)When operating the engine at idle speed, the centrifugal clutch assembly will not fully disengage, allowing the multi accessory discs to rotate at low speed.
b)When the engine is advanced to and/or from the idle speed position, erratic machine movement or "grinding" and "thrashing" noises from the clutch area are detected.
In many cases, clutch assembly removal, a cleaning of the bearing surfaces and reassembly will solve the problem.

9)The centrifugal clutch is comprised of a rotor/shoe assembly, a drum/pulley assembly, a thrust washer and retaining snap ring.
a)Using the snap ring pliers, remove the snap ring from the clutch assembly. FIGURE 45.
