2. Construction
This two-speed percussion drill is an electric tool of Class II
with protective insulation without earth wire and in accordance
with VDE regulations 0740. The protecti ve insul a tion is addi-
tional to the normal insulation and is attained by the shockproof
motor housing made of Polyamide and by insulating the arma-
ture shaft against the gearing. The drill is tested with the pre-
scribed test voltage of 4000 V. The machine is radio suppressed
according to radio interference degree N. It is supplied with a
two-cor e cable without earth wire and mu st not be ear thed .
Type DSk 736 for low tension (v oltag e 42 Volts) is of the same
design but without double insulation and not radio suppressed.
To prevent damage to the insulation no additional marking
pl ates and signs must be riveted or screwed on th e housing.
We recommend the use of transfers only.

3. Connection and Operation
Main vo ltage must corre s pond to the operq. ti ng volt age marked
on the r ati ng plate. The to ol can be plugged in to plain or safet y
sockets .
Switch must be in the uoff" position when connecting!
Remove the grease of the cones before dismantling the morse
taper.
Attention! Before changing speed, machine has to be switched off.
4.
Maintenance
Before carrying out any maintenanc e work always remember
to pull out the plug. To guar a ntee the security provided by the
double insulation clean the machine regularl y every 300 dut y
hours . This is done with a brush or by blowi ng out the carbon
hold ers an d the insulated p art s with dr y pn eumatic air. After
checking the carbon brushes make sure to re fit t hem in th eir
original position and check that the y mo ve easil y in th e ir hold er.

They should be replaced at the latest when they have worn
down to 7 mm (1/4"). Please, only use original Fein carbon
brushes. After fitting ne w brushes run tool unloaded for about
15 min~tes to allow brushes to bed in. One pair of spare carbon
brushes (21) will be found in the cover of the handle, please, do
not forget to reorder them in time.
In order to prevent accidents check cable at regular intervals.
To replace the cable take off the screws (24, 25), then take off
the handle cover (20), loosen the two screws (19) of the terminal
clamp (18) and clamp off the cable from th8 switch (2).
5. Lubrication
We recommend to renew the gear . grease after 300 duty hours.
Please, only use the Fein special grease FG 12. For ball bearing s
which should be lubricated after approx. 900 duty hours we re-
commend our ball bearing grease FK 3. The ball bearings are
to be rinsed in clean solvent and packed with new grease.
The space between inner and outer ring is to be one third filled
with grease in order to prevent that the bearings do not over-
heat.

No claims can be entertained for damage due to negligent main-
tenance and inadequate lubrication.
6.
Overhaul
After 900 duty hours the machine sh ould be completely dis-
mantled as described under paragraph 7 and all parts should
be thoroughl y cleaned. Rinse ball bearings and gears in clean
solvent and pack with fresh grease as per paragraph 5.
Please be sure that all electric parts are only cleaned dry.
7. Dismantling
1. Unscrew fillister head screw (25) an d the two cyl i ndr ical
scr ew s (24), then take off handle cover (20).
2. Re mov e supply cab le from switch, draw out switch and dis-
connect motor cable.
After unscrewing the screws (10) dra w out carbon holder (5),
unscrew screw (4) and pull out radio inte rference capacitor (3).
3.
Unscrew cylindrical screws (60) and (61) and remo ve ou t er
bearing (35) with intermediate bearing (34).
4.
Take apar t outer bearing (35) and, only if necessary, the
speed-changing mechanism in the following manner:
Press fixing bolt (53) in direction of point of morse taper
through the bores of the parts (52) and (54) (pin punch 0.08
inch.), pull trigg er (52) out of switch bo lt (54) and di smantle
drill shaft .
5.
Pull out armature (26), unscrew the three screws (31) and
remove armature drive (30).
6. Draw insulatio n ring (1 5) out of motor housing (1), unscrew
cylindrical screws (14) and remove po le housing (12).
Re-assemble in re verse sequence .
Pl ease, b ear in m ind that existing washe rs are to be placed in
right places. The ir loss would lead to damage.
8. Repair and spare parts
We recommend our Fein Service Stations to carry out all over-
haul and repair work quickly and expertly.
Please quote Order Reference when ordering spare parts or
send in sample part, quoting the type of the machine.
We draw your attentio n to the need to carry out a high voltage
test in accordance w ith your local regulations (or VDE regu,
la tion 0740) before taking a tool into service after any repa ir
carried out by yo ur own staff .
