2. Construction
The hand drill ASk 658 is an electric tool of Class II with pro-
tective insulation according to VDE regulations 0740. The
protecti ve insulation is additional to the normal insulation and
separates all accessible parts of the metal casing from all
internal parts liable to be come live.
Th e machine must not be earthed and must be connected with a
two-core cable without earth wire.
The drill is tested with the prescribed test voltage of 4000 V.
The machine is radio suppressed according to radio interference
degree N.
To prevent the overbridging of the insulation no additional
marking plates and signs must be riveted or screwed o~ the
housing. We recommend the use of transfers only .
Type ASk 758 for low tension (42 Volts) is of the same design,
but not radio suppressed.
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.

4. Maintenance
Before carrying out any maintenance work always remember to
pull out the plug.
Every 300 duty hours blow or brush out the tool with special
attention to carbon brush holders and insulat ed parts in order
to guarantee the safety given by the protective insulation.
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 .
Worn carbon brushes automatically switch off the machine after
reaching their minimum length.
Please, only use original Fein carbon brushes.
In order to prevent accidents check cable and connections at
both sides at r eg ular intervals.
After 900 duty hours the machine should be completely dis-
mantled as described under paragraph 6 and all parts should be
thoroughly cleaned. Rinse ball bearings and gears in clean sol-
vent and pack with fresh grease as per paragraph 5.
Please be sure that all electric and plastic parts only cleaned
dry.

5. Lubrication
Vve recommend to renew the gear grease after 300 duty hours .
Please: only use the Fein special grease FG 13. For ball and
needle bearings which should be lubricated after approx. 900
duty hours we recommend our ball be aring grease FK 3.
The space between inner and outer ring is to be one third filled
with grease in order that the bearings do not overheat.
For good and adequate lubrication and to avoid overheating it
is . important to pack gearing and brearings with the grades and
quantities of grease listed in the table below.

6. Dismantling
1. Pull plug from socket.
2. Take off motor housing cover (11), take out carbon brushes
(10).
3. Take off handle c~:JVer (78), loosen supply cable and interior
connection cables from switch (80). Tak e . 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
(59).
5. Unscrew four screws (61), take oute r bearing (22), in t erme-
diate bearing (21) with armature (15) off motor housing ( 1)
and push armature (15) togeth er w ith fan and groove ba ll
bearing (20, 57) out of intermediate bearing (21).
6. Draw countershaft (38) out of outer bearing (22).
7. Unscrew nut (37), draw off drill shaft gear wheel (36) , take
out fitting key (35), push out drill shaft (26).
Pay attention to washers!
8. Only in case of da mage take out i ns ula tor (2) with stator ( 6)
after pulling supp ly cable throu gh the lateral boring i nto the
housing and unscrewing screws (4) .
Re-assemble in reverse sequence .
7. Stationary use in the bench drill stand
If th e machine remains fixed to the benc h drill stand the gear
grease is no t sufficiently c hang ed . Regrease once a we ek w ith
the grease gun .
After operation do no t keep the magnetic bench drill stand w ith
t he fixed machines in a vertical positio n but in a horizo ntal one
so that the gear g rease is distributed equally.
8. Repair and Spare Parts
We recommend our Fein Servic e Statio ns to carry o ut 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 atte ntion to the need to carry out a high voltage
test in accordance w ith your local reg u la tions (or VDE regu-
lation 0740) before t ak ing a tool into se r vice after any repair
carried out by your own staff.
