Construction
The sheet metal shear QSz 636 is an electric tool of Class II and
is in accordance with the VDE regulations 0740. The protective
insulation is additional to the normal insulation and p rotects 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.
Type QSz 736 (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.
To prevent the overbridging of the insulation no additional
marking plates and signs must be riveted or screwed on the
housing. We recommend the use of transfers only.

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 machine performs quick and clean cuts when blades are in-
serted
a~d adj
usted in accordance with the instructions. Stops or
jams only occur when shear is worked in the wrong position

and will be eliminated as soon as the shear is brought by the
right touch in the right position. Use no force!
If
necessary switch off motor and restart cutting operation.
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 unscrew ing 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 brushe s, run tool unloaded for about
15
minu-
tes to allow brushes to bed in.
One pair of spare carbon brushes 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 (1 9) and take out cable.
Use Universal Grease type
