2. Construction
The hand grinder MSh 636-1 is an electric tool of Class II and is in
accordance with the VDE regulations 0740. The protective insu-
lation is additional to the normal insulation and protects the
operator against electric accidents which may be caused by de-
fects in the normal insulation . The pole housing is insulated by
the motor housing made of shockproof Polyamide and the elec-
tric parts of the armature are protected by a separating insula -
tion against the drive shaft. The machine is supplied with a two-
core cable without earth wire and must not be earthed. The high
voltage test is made with the prescribed test voltage of 4000
Volts. The machine is radio-suppressed according to radio inter-
ference degree N.
The bearings are protected against the ingress of grinding dust.
Type MSh 736-1 (42 V) is of the same design but without double
insulation. This type must also be connected with a two-core
cable without earth wire.
In order to prevent the overbridging of the insulation no addi-
tional marking plates and sings must be riveted or screwed on
the housing. We recommend the 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.
Do not use grinding wheels exceeding the max. diameter stated
in the table. In order to avoid accidents observe the security
prescriptions for grinding.

4. Maintenance and Lubrication
Before carrying out any maintenance work always remember to
pull out the plug .
Every 100 duty hours the tool should be cleaned thoroughly in
order to guarantee the safety given by the protective insulation.
For this purpose carbon holders and insulated parts must be
cleaned of carbon and grinding dust. This is done by means of a
brush or by blowing out the tool with dry pneumatic air or a
hand blower.
For checking the carbon brushes the carbon holders (10) can be
taken out after unscrewing the screws (12). Make sure that the
carbon brushes are refitted in their original place and that they
move easily in their holder. They should be replaced at the
latest when they have worn down to 7 mm (1/4"). Please, only
use original Fein carbon brushes (Order Reference EZ 11-62).
After fitting new brushes, run tool unloaded for about 15 minu-
tes to allow brushes to bed in.
One pair of spare carbon brushes (70) will be found in the motor
housing; please, do not forget to reorder them in time.
In order to prevent accidents check cable at regular intervals.
To replace the cable unscrew the screws (22) and (23) and re-
move the cover (21). Clamp off cable from switch (14). unscrew
screws (20) at cable clamping bridge (19) and take out cable.
After approx. 900 duty hours clean the machine thoroughly. For
this purpose dismantle the tool according to paragraph 5. The
ball bearings are to be rinsed in clean solvent and packed with
new grease. In order to prevent overheating of the bearings, the
space between inner and outer ring is to be filled one third with
grease . For this purpose we recommend our ball bearing grease

5. Dismantling
Th e tool should only be taken a part by an expert.
1. Re move screws (22) and (23) and take off motor housing
cover (21) .
2. Clamp off pole-housing supply-cable (6), capacitor supply-
cable (15) and cable (17) from switch (14) and take out switch.
Unscrew screw (16) and remove capacito r (15).
3.
Remove screws (12), then take out carbon holders (10).
4. Unscrew screws (56) an take off spindle bearing (35), remove
clutch piece (55) and draw int ermedia te bearing (51) with ar-
mature (26) out of motor housing (1).
5.
Remove grease retaining ring (9), unscrew screws (8) and
take out pole housing (6) .
6.
The clutch (54) at motor side must only be drawn off by
me ans of the withdrawal device ZSO 24-4-1 (see illustration ).
Fit nut (M) with r ecesse d portion onto the clutch (54) and
turn until it stops . Screw spindle (S) with boreside (not with
internal thread) into nut (M) and turn until the clutch is drawn
off.
7. Remove fitting key (53) and draw out armature (26) at inter-
mediate bearing (51), unscrew screws (31) and take off clutch
shaft (30).
54 s
Attention! To maintain true running conditions ne ve r use
force.
8. Unscrew protecting sleeve (44) . D raw drive shaft (37) out of
grinding-wheel spindle bearing (35). Take off Seege r circlip
(43), spring washe r (42) and ball bearing (41).
Re-assemble in reverse sequence.
In order to pre ve nt damage to th e armature wheel the clutch (54)
at motor side must only be forced on by means of the device
ZSO 24-4-1. Work in the following sequence (see illustra tio n):
Screw nut (M) totally onto the spindle (S) at the \nternal thread
(not at bore-side ). Slip clutch (54) onto sp indle and screw spind le
(S) onto threaded pin of the clutch. Adjust groove of fi tt ing key
of the clutch to fitting key and forc e on clutch by turning nut (M).
