DFG-SERIES SURFACE GRINDERS OPERATION AND PARTS MANUAL REV #4 (05/28/09) PAGE 46
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 ge
ars. The transmission should not
require additional lubrication or the lubrication to
be changed until service work to the gears is
performed.
4) Standard grea sing 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 slipp
age 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 ma ny
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 relubrica
tion 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
M
anual 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.
