SFG10E ELECTRIC SURFACE GRINDER — OPERATION AND PARTS MANUAL — REV. #1 (07/16/07) — PAGE 35
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 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
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.
