Construction
This screw-driver is an electric tool of Class II with protective
insulation without earthing con ductor and is in accordance with
the VDE regulations 0740. The protecti ve insul a tion is attained
by the shock-proofed motor housing made of Polyamide and by
insulating the armature against the pinion. The protective
insulation is tested with the prescribed test voltage of 4000 V.
The machine is radio-screened in accordance with radio inter-
ference degree N. It is supplied with a two-core cab le without
earthing cond uctor and must not be earthed.
Type ASs 736-1 b for low tension (42 V) is of th e same design,
but without double insulation and not radio-screened.
The 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 screw ed on the
housin g. We recommend the use of transfers only.
3. Connection
Before plugging in the tool check that voltage stated on the
rating plate is in accordance with the voltage of the mains
supply.
Switch must be in the "Off" position when connecting.

4. Adjustment of the torque
The machine is provided with a positive clutch. The torqu e is
adjus ted by changing the position of the clutch claws; the
deeper the gripping of the claws, th e high er the torque.
In order to adjust the claws, turn screw (46) after having
screwed off bearing sleeve (48 ) and loosed grub screw (47) .
Moreover , the torque is dependent on the pressur e of the driver
against the screw.
5. Setting of the depth stop
With ad justing sleeve (102) you can set in the screwing depth.
A turn of 90o corresponds of 25 mm (1 ") screwing depth . A
deeper stop results from right turning.
In order to change the blades, loosen screw (105), re move depth
stop, cha nge the blade and r emove plaster dust. Push depth
stop on t he machin e up to str i king and pull on screw (105).
6.
Maintenance
Before carrying out any maintenance work always remember
to pull out the plug. To guarantee the securi ty provided by the
double in s ulation clean the machine regularl y every 300 duty
hours. Th is is done with a brus h or by blowing out the carbon
holders a nd the insulated parts with dry pneuma t ic air. Aft er
checking
the carbon brushes make sure to ref it them in their
original position and check that they mo ve easi ly in their hold er.

They should be replaced at the latest when they have worn
down to 7 mm Cf4 "). Please, only use original Fein carbon
brushes. After fitting new brushes run tool unloaded for about
15 minutes 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 the switch (2).
7. Lubrication
We recommend to ren ew the gear grease after 300 duty hours.
Please, only use the Fein special grease Sst 1. For ball bearings
which should be lubricated after approx . 900 duty hours we re-
commend our ball bearing grease Sst 1. 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.
8.
Overhaul
After 900 duty hours th e machine should be co mplet ely dis-
mantled as described under paragraph 9 and all parts should
be thoroughly cleaned. Rinse ball bearings and gears in clean
solvent and pack with fresh grease as per paragraph 7.
Please be sure that all electric parts are only cleaned dry.
9. Dismantling
The tool should only be taken apart by an expert .
I. 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 and
disconnect motor cable.
3. After unscrewing the screws (10) draw out carbon holder (5).
Push reversing switch (4, 4 a) backwards. Distribution of con-
nections see connecting plan .
4. Loosen cylindrical screws (54, 55), remove outer bearing (35)
with intermedia te bearing (34) and take apart.
5. Pull out armature (26), unscrew three screws (31) and remove
armature drive (30).
6. Draw insulation ring (14) out of mo tor housing (1), unscrew
cylindrical screws (13) and remove po le housing (12).
Re-assemble in reverse sequence.
Please bear in mind that existing washers are to be placed in the
right places. Their loss would lead to damage.
10. Repair and spare parts
We recommend our Fein Service Stat io ns 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, 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 r eg ulations (or VDE regu-
lation 0740) before taking a tool into service after any repair
carried out by your own staff.
