2. Operation
Remove all signs of grease from chuck.
Main voltage must correspond to the operation voltage marked
on the rating plate. Switch must be in "Off" position when
connecting.
To prevent the overbridging of the insulation no additional
marking plates and signs must be riveted or screwed. We
recommend the use of transfers.
Changing of the speed.
Push slide valve (55) into the position I or II. Change speed only
at stand-still of the machine.

that they move easily in their holder. Run tool unloaded for 5. Stationary use in the bench drill stand
about 15 min.
Check connection cable at regular intervals. To replace unscrew
screws
1 (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
The tool should only be taken apart by an expert.
1. Loosen screws (20, 21), remove handle cover (19).
2. Clamp 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 (70, 71), 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.
If the machine is constantly used in the bench drill stand
remove drill after 50 working hours and turn by 180° jus t after
operation to lubricate the pinion. After 150 working hours check
the lubrication of the pinion. Loosen screws (70, 71) and take
off gear head.
6. Repair and Spare Parts
We recommend our Fein Service Stations to carry out all over·
haul and repair work quickly and exper tl y.
We deliver a special spanner ZSO 21-3-1 to turn out t he
t hreaded ring (45) - (left-hand thread).
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 r egu l a-
tion 0740) before taking a tool int .o service after any repair
carried out by your own staff.
