2. Construction
The sheet metal shear QSz 663 is an electric hand tool fitted with
protective insul ation according to C la ss II of the VDE Specifications
0740. In ad dition to the norm al i nsulat i on th e tool is equipped with
a further protective insu,lation. Thereby the touchable external metal
housing is
separated from all internal parts, which can become live
in case of failure. The dustproof switch is built into the plastic handle.
The tool is not to be earthed and must be connected with a two -core
cable :
without earth wire.
The r~dio suppression of the machine is in accordance wi th r adio
suppression degree N.
Type QSz 63 K for low tension (voltage 42 V) is of the same design,
but without double insulation.
To pre ve nt the overbridging of the in s ulation no additional marking
plates and signs must be riveted or screwed on the housing. We re-
commend
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 inserted
and adjusted in accordance with th e instructions. Stops or ja ms only
occur w hen s hear is worked in the w rong po sition a nd will be
eliminated as soon as
the shear is brought by th e ri g ht touch in the
right position. Use no force! If necessary switch off motor and restart
cutting operation.
Attention. Do not cut we lding seams.

Fitting and adjusting of the blades
Insert fixed blade and plun ge r blade (116) and secure sli ghtly with
sc re ws (117). Turn set sc rew (101) until the corners of the blades at
high es t plunger position overcross at about 0.5 mm (0.2 in) (Dim en-
sion F). Screw
and plunger blade sho uld then be tightened.
Hereafter the fixed blade should finally be adjusted by set screw
(108) so that the gap "L" is 1/10 of the sheet thickn ess to be cut.
(e.g. sheet metal
of 2 mm thickness- 0,2 mm).
highest
position
l owes t
p
os ition
Attention! Never work with blunt blades! For resh ar pening, th e
blades
ca n be removed after unscrew ing the t wo sc rews (117). When
sharpening use plent y of coolant a nd strictly ob se rve the prescribed
cutting angle. If blades are resha rpened in time, breaking out is
avo ided . The fi xed bl ade and the plunger bla de are interchangeable.
No claims ca n be entertained for damage due to work w ith materia l
of too much strength or sheet too thick or work with b lunt blades.

4. Maintenance and Lubrication Grease chart for the shear head
Before
1
carrying out any maintenance work always pull out the plug.
. When checking the carbon brushes make sure that they are refitted in
their original place and 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
11-49, QSz 63 K = EZ 11-38). After fitting new brushes, run tool un-

loaded for about 15 minutes to allow brushes to bed in. No claims can be entertained for damage due to negligent mam-
tenance or inadequate lubrication.
In order to prevent accidents check cable at regular intervals. To
replace the cable see § 5, Pos. 4. ., 5. Dismantling
Clamp off cable from switch, unscrew screws at cable clamping bridge
(29) take out cable.
Every 300 duty hours blow or brush out the tool with special attention
to carbon brush holders and insulated parts in order to guarantee the
safety given by the protective insulation.
The shear head being the power transmitting element requires a good
lubrication. The gear grease should be filled up after approx. 100
working hours. Please only use special FEIN gear grease FG 11. A
mixing of this grease with other greases endangers the greasing capa-
cities, and therefore also use FG 11 grease for the roller bearings in
the shear head. After 300 working hours renew gear grease, Unscrew
socket hexagon screws (61), take off gear head, rinse in clean solvent
and pack with FG 11. After appro x. 100 working hours refill the gear
grease.
For this purpose unscrew socket hexagon screw (84), remove
handle (80), then unscrew socket hexagon screw (83) and remove
handle setting sleeve (81).
Re-assemble in reverse sequence.
After 900 w orking hours the machine should be cleaned thoroughl y.
For this purpo se the machine is dismantled as described in paragraph 6
and the individu al parts are then cleaned. The ball bearin gs (35) and
(45) are rinsed in clean solvent and, when dry, packed with special
grease
FK 3. In order to prevent overheating of the bearings at high
speeds
the space between inner and outer ring of the bearing should
be filled only about
1/s
with grease.
The tool should onl y be taken apart by an expert.
1. Take off motor housing cover (12) and draw out carbon brushes
(19).
2.
Unscrew scr ew s (115) and take off shear head with counter s haft.
3. Unscrew screws (61), then dra w out intermediate bearing (43)
and armature (40).
4.
Unscre w screws (33), then take off handle (upperpart) (32) a nd
switch. Unscrew screws (62) and take off handle.

We recommend our Fein Service Statio ns to carry out all o ver haul
and repair work qu ickly and expertl y.
Please quot e Order Reference w hen ordering spare parts or send
in sample pa rt.
We draw your attention to the need to carry out a high voltage test
in accordance with y our local regulat ions ( or VDE regu l ation 0740)
before taking a tool into service after an y repair carried out by your
own staff.
