Stow Grinder DFG Series Manuel D’Utilisation

 

 

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.
