MAINTENANCE/SERVICE
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. FIGURE 51.
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
ELECTRIC MOTOR SERVICE
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.
