MAINTENANCE/SERVICE

Excessive amounts of grease in the bearing race cavity can actually increase friction and resulting heat increases that can also dramatically shorten bearing service life.

Figure 51. Lubrication Points

3)The transmission gears are lubricated at the time of assembly with approximately 24 ounces of Lubricate GR132 grease or equivalent. This lubricant has an EP additive to better allow it to cling to the gears. The transmission should not require additional lubrication or the lubrication to be changed until service work to the gears is performed.

4)Standard greasing intervals will range from once every 8 hour work day to approximately once every work week. Always maintain sufficient grease around the circumference of the bearing insert to provide its self-aligning feature and prevent the formation of corrosion.

5)Do not apply belt dressing materials to the V- belts for the purpose of minimizing slippage. These products typically attract foreign material accumulations that can accelerate component wear. Excessive V-belt slippage can be eliminated with proper V-belt tension and alignment.

ELECTRIC MOTOR SERVICE.

Application: DFG/E Series SURFACE GRINDER. The electric motor is capable of operating for many years with a reasonably small amount of maintenance. Before attempting to service the motor, disconnect the SURFACE GRINDER from the power source. Clean the motor surfaces

periodically, preferably with a vacuum cleaner. Heavy accumulations of dirt and lint will result in overheating and premature failure of the motor.

The electric motor is equipped with higher capacity ball bearings and under normal service and ambient temperatures should not require relubrication for many years. If you feel that the motor requires relubrication, contact the local representative of the motor manufacturer for specific information.

The seals utilized with the motor are intended to deliver a longer service life in a concrete dust environment. When replacing the seals, utilize only components meeting the original factory specifications.

ENGINE SERVICE.

Application: DFG/G Series SURFACE GRINDER. Consult the material supplied by the engine manufacturer for specific service and maintenance information regarding:

1)Muffler

2)Spark Plug

3)Air Filter System

4)Carburetor Adjustment

5)Ignition System

6)Short and Long Term Storage

7)Maximum Governor Speed

8)Emission Standards

Keep this information stored with the Operator's Manual for the SURFACE FigureGRINDER so it will always be available for use when the engine requires service or maintenance. A properly maintained engine will add considerably to the service life and overall productivity of the SURFACE GRINDER.
