1)
Grinding wheel for 147 ft./s max.
2. Operation
Switch in "Off" position.
Main voltage must correspond to the operating voltage marked
on the rating plate .
To prevent the overbridging of the insulation no additional
marking plates and signs must be riveted or screwed. We re-
commend the use of transfers.
Grinding wheels: Only use grinding wheels with the admissible
peripheral speed. In any case pay attention to your local safety
regulations on the use of grinding wheels.
3. Maintenance and lubrication
Pull out the plug before carrying out any maintenance work.
After 100 working hours clean air openings of the motor hous-
ing. Blow out motor with dry pneumatic air.
Clean electric parts only dry.
Replace carbon brushes when they have worn down to 7 mm
(0.28 in). To replace brushes see paragraph 4, section 4.
Only use "Fein" carbon brushes.
After fitting new brushes, run tool unloaded for about 15 min.

Check cable at regular intervals. To exchange cable, see para-
graph 4, section 4.
After 300 working hours renew the gear grease. Quantity of
grease: 75 g. Order Reference for tube of approximately 90 g:
MZ 60-3/Sst 1. Only use Fein special grease Sst 1. A mixing of
this grease with other greases endangers the greasing capaci-
ties.
After 900 working hours clean machine thoroughly. Rinse ball
bearings in clean solvent and pack with fresh grease Sst 1. Only
the anti-friction bearing (54) must be greased with grease FK 5.
Order Reference for the tube of 5 g: MZ 60-5/FK 5. Fill space
between inner and outer ring only one third with grease. For
good and adequate lubrication and in order to avoid over-
heating it is important to pack the gearing with the grades and
quantities of grease given. Dismantling see paragraph 4.
No claims can be entertained for damage due to negligent main-
tenance and lubrication.
4. Dismantling
The work should always be left to an expert.
1. Unscrew screws (55). take off outer bearing (30).
