Construction
T hi s sc r ew-d ri ver is an electric tool of Class II w ith protective insulat-
ion without earthin g conductor and is in accordance with the VDE
regulations 0740. Th e protective insulation is attained by the shoc k-
proof motor hou sing made of Polyamide an d by insulating th e arm a-
tur e aga in st th e pinion. The prot ec ti ve insulation is tested wit h the
prescribed test vo lt age of 4000 V. Th e machine is radio suppressed in
accordance w ith radio int erfe rence degree N. It is supplied wi th a
t
wo -cor e cable w ithout eart hin g conductor and must not be eart hed.
Ty
pe ASs 736 for low tension (42 V) is of the same design, but with ~
out double insulation and not radio s uppr essed.
The machine is pr ovi ded with a rever s in g switch for clockwi se a nd
anticlockwise rot ation. It must not be operated when the machine
is running.
To pr event the overbridgi ng of the in sulation no addit i ona l mark in g
plates
and signs must be ri ve ted or screwed on the hou sin g. We
recommend the use of transfers only.
3. Connection
Before plu gg in g m the tool check that vo lt age st ate d on the rating
plate is in acco rdance with the voltage of t he mains supp ly.
Switch must be in the "Off" position when connecting.

4. Adjustment of the torque
The machine is pro v ided w ith a positive clutch. The torque is adju sted
by changi ng the positi on of the clut ch claws; the deeper the gripping
of the claws, the higher the torque .
In order to ad ju st the claws loosen securing screw (56), then turn
sc r ew (55).
Moreover, the
torqu e is depe nd e nt on th e pressure of th e driver agai nst
the sc re w.
5. Maintenance
Befor e carr y ing out any maintenance work al ways re m ember to pull
out the plu g.
Eve ry 300 dut y hours blow or brush out th e tool with special a tt en tion
to car bon brush ho ld ers and ins ulate d parts in orde r to gua r antee the
safety gi ven by the protective insulation.
After checking the carbon bru shes m ake sure to r efit them in their
original position and check th at th ey move easily in their holde r.
They sh ou ld be repla ced at the latest when th ey h av e worn do wn to
7 mm (1 /4"). Please, on ly use o ri ginal Fein carbon brushes. Aft er fitting
new brushes,
run tool u nl oaded for a bout 15 minute s to allow bru shes
to bed in. One pair of spare ca rbon br ush es w ill be f ound in th e cover
of th e hand le; please, do not forget to reorder them in time.
From August 1970, gear and ball bearin gs are pr ovided with
the special gre ase Sst 1. Correct quantity for gear 20 g.

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 t20), loosen the
two screws (19) of the terminal clamp (18) and
clamp off the cable from the switch (2).

Lubrication
We recommend to renew the gear grease after 300 duty hours. Please,
only use the Fein special grease FG 12. For ball bearings which should
be lubricated
after approx. 900 duty hours we recommend 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 that the bearings do not overheat.

No claims can be entertained for damage due to negligent
maintenance and inadequate lubrication.
7. Overhaul
After 900 duty hours the machine should be completely dismantled
as described under
paragraph 8 and all parts should be thoroughly
cleaned. Rinse ball
beari~gs and gears in clean solvent and pack with
fresh grease as per paragraph 6.
Please be sure that all electric parts are only cleaned dry.
8. Dismantling
The tool should onl y be taken apart by an expert.
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 and disconnect
motor cable.
3.
After unscrewing the screws (10) dra w out carbon holder (5 ). Push
reversing swith (4) backwards. Distributi on of connections se e con-
necting
plan.
4. Loosen cylindrical screws (65, 66), remove outer bearin g ( 38 ) with
intermediate bearing (34) and take apar t.
5.
Pull out armature (26), unscrew three screws (31) and remove
armature drive (30).
6.
Draw insulation ring (14) out of motor housing (1), unscrew cylin-
drical screws (13)
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. Their loss would lead to damage.
9. Repair and spare parts
We recommend our Fein Service Stat ions to carry out all ov erhau l a nd
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 att ent i on to the need to ca rry out a high vo. lt ag e test
in accordance w
ith y our local regulations ( or VDE re g ul a tio~ 0740)
before taking a tool i nto service after any repair carried out by y our
own staff.
