2. Construction
This screwdriver is an electric tool of class II with protective
insulation without earth wire and is in accordance with the
VDE regulations 0740. The protective insulation is attained by
the shockproof motor housing made of Polyamide - and by insulat-
ing the armature against the pinion. The protective insulation
is t ested with the prescribed test voltage of 4000 V. The machine
is radio suppressed in accordance with radio interference VDE
0875. It is supplied with a two-core cable without earth wire and
must not be earthed.
Type ASsd 736-1 for low tension (42 Volts) is of the same
design, but without protectiv e insulation.
Th e machine is provided with a reversing switch for clockwise
and anticlockwise rotation. It must not be operated when the
machine is running .
To prevent the overbridging of the insulation no additional
marking plates and signs must be riveted or screwed on the
housing. We recommend the use of transfers only .

After checking the carbon brushes make sure to refit them in
their original position and check that they _ move easily in their
holder. They should be replaced at the latest when they have
worn down to 7 mm (' //' ). Please, only use original Fein carbon
brushes (Order Reference EZ 11-59). After fitting new brushes
run tool unloaded for about 15 minutes to allow brushes to bed
in. One pair of spare carbon brushes will be found in th e handle
cover; 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 the switch (2).
6. Lubrication
We recommend to renew the gear grease after approx. 300 duty
hours. Please, only use the Fein special grease Sstl. Quantity
20 g. The order reference for the tube of approx. 90 g is MZ 60-3/
Sst 1. The ball bearings are to be rinsed in clean solvent and
packed with new grease Sst 1. The space between inner and outer
rings is to be one third filled with grease in order to prevent
overheating
of the bearings .
Please be sure that all electric parts are only cleaned dry.
No claims can be entertained for damage due to negligent
maintenance and inadequate lubrication.
7. Overhaul
After 900 duty hours the machin e should be completely dis-
mantled as described under paragraph 8 and all parts should
be thoroughly cleaned. Rinse ball bearings and gears in clean
solvent and pack with fresh grease as per paragraph 6.
8. Dismantling
The tool should only be taken apart by an expert; first relieve
stresses of adjusting ring (68).
NOTICE!
1. Unscrew fillister head screw (25) and the two cylindrical
screws (24), then take off handle cover (20).
2. Remove supply cable from switch , draw out switch an d dis-
connect motor cable.
3. After unscrewing screws (10) draw out carbon holders (5).
Push reversing switch (4) backwards . Distribution of connec -
tions see connecting plan.
4. Unscrew fillister countersunk screws (7 1) and draw off guide
bushing (57).
5. Unscrew cylindrical screws (84 and 85), remove and dismantle
outer bearing (38) with intermediate bearing (34).
6. Pull out armature (26), unscrew 3 screws (31) and remove
armature drive (30).
Attention! To maintain true running conditions never use
force.
7. Draw insulation ring (14) out of motor housing (1). unscrew
cylindrical screws (1 3) and remove pole housing (12).
Re-assemble in reverse sequence . Please, bear in mind that
existing washers are to be placed in the right places . Th e ir
lo ss may lead to damage.
9. Repair and Spare Parts
We recommend our Fein Service Stations for carrying out all
overhaul and repair work quickly and expertly .
When ordering spare parts, please, quote Order Reference or
send in sample part, stating the type of the machine.
We draw your attention to the need to carry out a high
voltag e 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.
(
e Reversing switch for clockwise and anticlockwise rotation must only ~
be actuated when the motor is switched off.
e When screwing, press machine with tool tightly againstthe work-piece.
