2. Ope ation - t ------·-· ----..J
Remove all signs of grease from chuck.
Main voltage must correspond to the operation voltage marked on the
rating plate. Switch in
"Off" position.
To prevent the overbridging of the insulation no additional mark-
ing plates and signs must be riveted or screwed.
We recommend the use of transfers.
3. Maintenance and lubrication
Pull out plug before carrying out any maintenance work.
After 300 working hours clean air openings of the motor housing.
Blow
out motor with dry pneumatic air.
Renew the gear grease. Loosen screws (50, 51)
and take off gear head.
Only use the Fein special grease FG 12.
After 900 working hours clean machine thoroughly. Rinse gears in
clean solvent
and pack with fresh grease FG 12. Rinse ball bearings
in clean solvent
and pack with fresh grease for ball bearings FK 3.
Dismantling see paragraph 4.

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, sections 1 and 3. Only use Fein
carbon brushes.
After fitting new brushes check that they move easily in their holder.
Run tool unloaded for about 15 min.
Check connection cable at regular intervals. To replace unscrew screws
(20, 21), remove cover (19), loosen screws (16) of the terminal clamp
and clamp off cable from switch (12).
No claims can be entertained for damage due to negligent main-
tenance and inadequate lubrication.

4. Dismantling
1. Loosen screws (20, 21), remove handle cover (19).
2. Clqmp off cable from switch (12), clamp off capacitor (17) at
motor housing (1).
3.
Clamp off carbon cable, pull carbon brush (5) out of holder.
4. Loosen screws (50, 51), remove and dismantle outer bearing (37)
with intermediate bearing (36). Draw out drill shaft (39).
5.
Pull armature out of motor housing.
6.
Pull air conducting ring (10) out of motor housing, loosen screws
(9),
take out pole housing (7).
Re-assemble in reverse sequence.
S. Stationary use in· the bench drill stand
If the machine is constantly used in the bench drill stand remove drill
after 50 working hours and turn by 180° just after operation to
lubricate the pinion. After 150 working hours check the lubrication of
the pinion. Loosen screws (50, 51) and take off gear head .
6. Repair and Spare Parts
We recommend our Fein Service Stations to carry out all overhaul
and repair work quickly and expertly.
Please quote Order Reference when ordering spare parts or
send in sample part, stating the type of the machine.
We draw your attention to the need to carry out a high voltage test
in accordance
with your local regulations (or VDE regulation 0740)
before taking a tool into service after any repair carried out by your
own staff.
