2. Construction
The four spee d hand drill DDSk 672 is an el ectr ic tool of
Class II with protective insulation according to VDE regulations
0740. The prot ec tive insulation is additional to th e normal in-
sulation and separates all accessible parts of the metal casing
from all internal parts liable to become live.
The machine must not be ea rth ed and must be connected with
a two-cor e cab le without earth wire.
The drill is tested with the pr escribe d test vo ltag e of 4000 V.
The maschine is radio suppressed according to radio interfe-
rence VDE 0875.
Type DDSk 772 for low tension (42 V) is of the same design but
not double insulated.
To prevent the overbridging of the insulation no additional
marking plates and signs must be riveted or screwed on the
housing. We recommend th e use of transfers only.
3. Connection and operation
Main voltage must correspond to the operating voltage marked
on the rating plate. The tool can be plugged into plain or safety
sockets .
Switch must be in the "Off" position when connecting.

The speed of the machine must only be cha nged at stand-s till
or at slowing down without load . Release switch handle (54) of
its longi tu dinal position , put it across by t urni ng it out, then
push it in to the wanted switch direction and reset the switc h
handle in opposite direction again into its longitudinal position.
4. Maintenance and lubrication
Before carrying out any maintenance work always remember
to pull out the plug.
After approximately 300 working hours clean ai r openings of
the motor housing. Blow out motor with dry pneu matic air.
Renew gear grease. Only use th e Fein s peci al grease Sst . 1.
Quantity of g re ase 250 g. Order Refe ren ce for th e tube of
approx imat ely 180 g: MZ 60-4/ Sst 1. Ord er Re feren ce for a tin
of approx i mately 900 g: MZ 32-7/ Sst 1.
After 900 duty hours the machine should be completely
dism antled and all parts should be thorou ghly cleane d. Rinse
ball bearings and gears in cle an solvent and pack with fresh
grease Sst 1.
The space between inner and outer ring is to be one third filled
with gr ease in order that the bearings do not overheat.

Ple,ase be sure that all electric and plastic parts are only
cleaned dry.
For good and adequate lubrication and to avoid overheating
it is important to pack gearing and bearings with the grades
and quantities of grease.
Worn carbon brushes automatically switch off the machine after
reaching their minimum length. Only use Fein carbon brushes.
After checking the carbon brushes make sure to refit them in
their original position and check that they move easily in their
holder. After fitting new brushes, run tool unloaded for about
15 minutes to allow brushes to bed in.
In order to prevent accidents check cable and connections at
both sides at regular intervals.
No claims can be entertained for damage due to negligent main-
tenance and inadequate lubrication.
5. Stationary use in the bench d!ill stand
If the machine remains fixed to the bench drill stand the gear
grease is not sufficiently changed . Regrease once a week with the
grease gun at the greaser (18).
After operation do not keep the magnetic bench drill stand with
the fixed machines in a vertical position but in a horizontal one
so that the gear grease is distributed equally .
6.
Dismantling
The tool should only be taken apart by an expert.
1. Pull plug from socket.
2. Take off motor housing cover (4). unscrew carbon holder
caps (9) and take out carbon brushes (8) . .
3.
Take off handle cover (78). loosen supply cable and interior
connection cable from switch (80). Take out switch and clamp
off cable (85) together with protecting sleeve (83) from
clamping bridge (81).
4. Remove lower handle section (77). draw out insulation sleeve
(73).
5. Unscrew four screws (70), take outer bearing (20), inter-
mediate bearing (18) with armature (13) off motor housing
(1) .
6. Push out two clamping sleeves (53) of shift-bolt (48) and one
clamping sleeve (53) of shift-bolt (51) by means of a 3 mm
pin in direction of boring shaft, pull out switch handles (54)
with the two switch pins (49) and (52) at the side . Remove
the two switch pins (48) and (51) and pay attention to the
easily accessible clamping sleeves (53).
7. Draw countershafts (34). (39) and (42) out of outer bearing
(20) .
8. Unscrew hexagon nut (31), draw off drill shaft gear wheel
(30), take out fitting key (29), push out drill shaft (26).
Pay attention to washers!
9. Unscrew screws (68) completely of intermediate bearing.
Push out armature (13) with fan and ball bearing (62) .
lO. Only in case of damage take out insulator (6) with stator
(10) after pulling supply cable through the lateral boring
into the housing and unscrewing screws (3) .
Re-assemble
in reverse sequence.
7. 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, 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 regu-
lation 0740) before · taking a tool into service after any r~pair
carried out by your own staff.
8. Tools for Assembling and Disassembling
Tool for disassembling carbon holders. Order Reference: ZSo
77-7-1.
Spanner for mounting carbon holders. Order Reference: ZSo 71-6.
