2. Construction
The sheet metal shear QSz 636-1 is an electric -tool of Class II
and is in accordance with the VDE regulations 0740. The protec-
tive insulation is additional to the normal insulation and pro-
tects the operator against electric accidents which may b e
caused by defects in the normal insulation. The pole housing is
insulated by the motor housing made of shockproof Polyamide
and the electric parts of the armature are protected by a sepa-
rating insulation 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 accor-
ding to radio interference degree 0875.
Type QSz 736-1 (42 V) is of the same design, but w ithout
double insulation. This type must 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.
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 machine performs quick and clean cuts when blades are in-
serted and adjusted 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. Do not use force!
If necessary switch off motor and restart cutting operation.

4. Fixing and adjusting the blades
Insert shoe blade (47) in the slot of the shoe (48) and secure
slightly with the socket head cap screw (55). An eccentric
axle (43) is to be seen at the end side of the housing; it should
be turned with a screwdriver, so that a wide gap is reached
between plunger and shoe. Insert the plunger blade (46) in the
gear cutting, so that the corners of the blades overcross at
0,1 mm (0,004 in.) to 0,6 mm (0,02 in.).
A little distance (x) between the knife edge
points up to 0,3 mm (0,01 in.) raises the cut-
ting capacity on curves particularly for the
smaller r a dius.
Do not fo r get disc (56). securing ring (57). screw tightly the
socket head cap screw (55). When you turn the plunger blade
from 180
°,
the opposite cutting edge can be used.
The horizontal space, that is to say, the gap "L" between
the cutting edges of the two blades (L, see fig. a) should be
proper placed. This is very important for a fast and continuous
cutting. The thread ring (58) will be turned so long that this
gap "L" reaches the following values by sheet with strength
40 kp/ mm

(to 28.4 sh. ton/sq. in.).
when cutting the maximum sheet thickness (1 ,2 mm ; 0,047 in.)
=
0,24 mm (0,009 in.)
when cutting the smallest sheet: the gap "L" in mm = 0,2 x
sheet thickness (mm) ,
The giv en values are indications for the work of steel sheets
of normal quality. For the other materials with o ther strengths
and deformabilities, the gap "L" should be changed: for the soft
