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 op e rator against electric accidents which may be
caused by defects in the normal insulation. The pole housing is
insulated by the motor hou s ing made of shockproof Polyamide
and the e lectric 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 prescrib ed 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 i nsu lation. This type must be co nne cted 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
a nd will be e liminated as soon as the shear is brought by th e
right tou ch 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 t he slot of the shoe (48) and secure
slightl y 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 turn ed with a screwdriver , so that a wide gap is reached
between plunger and shoe . I ns ert the plunge r bla de (46) in the
gear cu tting, so that th e corne rs of the blades overcross at
0,1 mm (0 ,004 in.) to 0,6 mm (0,02 in.).
A
little distance (x) between th e knife edg e
points up to 0,3 mm (0,01 in. ) raises the cut-
ting capacit y on curves particu l arly for the
smaller radi us.
Do not for get disc (56). securing ring (57). screw tightl y t he
socket head cap screw (55). When you turn the plunger blade
from 180°, the opposite cutting edge can be used .
The hori z ontal space , that is to say, the gap "L" between
the cutting edges of th e two blades (L, see fig . a) should be
proper placed . This is very important for a fa st and continuous
c uttin g. The thr ead ring (58) will be turned so l ong that this
gap "L" reac hes th e fo llo wing va lues by sheet wi th strength

when cutting the maximum sheet thickness (1 ,2 mm ; 0,047 in .)
= 0,24 mm (0,009 in .)
when cutt ing the smallest sheet: the gap "L" in mm = 0,2 x

The gi v en values are indications for the work of steel sheets
of normal quality . For the other materials with ot her strengths
and deformabilities, the gap "L" should be changed: for the soft

and tough materials the gap "L" must be reduced, for the hard
and brittle materials, it should be enlarged .
After hi:lving adjusted the gap (L). the scre w (55) will be tightl y
screwed, the screw (58) will be turned aga inst the shoe blade
and the gap "L" once more controlled.
The blades should be taken out for resharpening by loosing the
screws (55). Do not lose the washers (56, 57).
When sharpening, use plenty of coolant and strictly observe
the prescrib ed cutting angles (fig. b. and c.)!
They are easy to check with the gauge, which is supplied free
of charge with the machine.
Their application is illustrated in fig. b. and c.

It is recommended to true regularly the c utting edges with an
oil stone.
No claims can be enter tained for damage due to work with too
thick sheets and materials and to work with inad equate or
blunt blades.
5. Maintenance and Lubrication
Th e machine must be (according to us e) greased once . a day at
the grease point with a gr ea se gun ( grease Sst 1). It should be
greased when the machine runs in no load, till clean grease goes
out at the plunger.
Before carrying out any maintenance work, always remember
to pull out the plug.
After 300 working hours clean cool air openings at the motor
housing. Blow out the motor with dry pneumatic air. Renew
gear grease . For this purpose take out shear head according to
§ 6 (4). Only use Fein sp ec ial grease Sst 1. This grease must not
be mixed with other greases.
Quantity of grease: 13 g. Order Reference for a tube with 90 g:
MZ 60-3/Sst 1.
After 900 working hours take apart the machine accord ing to
§ 6 and clean thoroughly. Clean parts of the gearing a nd ba ll
bearings in clean solvent and pack with fresh grease Sst 1. The
space between inner a nd outer ring is to be filled one third with
grease in order to prevent overheating of the bearings.
Clean electric parts only dry.
For checking th e carbon brushes, t he carbon holders (10, 10a)
can be taken out after unscrewing t he screws (13). Make sure
that the carbon brushes are refitted in th eir original place and
th at they move easily in their holder. They should be replaced
at the latest, when t he y have worn down to 7 mm ('// '). Please
only use original Fein carbon brushes (Order Reference EZ 11 -
62).
After fitting new brushe s, run tool unloaded for about
15 minutes to allow brushes to bed in. One pair of 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 in ter val s.
To
replace the cable, unscrew the screws (22) and (23) and
re move the cove r (21). Clamp off cable from switch (14),
unscr ew screws (20) at cable clamping bridge (19) and take out
cable.
No claims can be entertained for damage due to neg l igen t
maintenance and inadequate lubricatio n.
6.
Dismantling
The machine must only be tak en apart by an expert, working in
the following sequence:
1. Unscrew screws (2 2) and (23) and remove motor housing
cover (21).
2.
Clamp off connections to pole housing (6). capacitor (15) and
cable (17) at swit ch (14) and take out switch. Unscrew screw
(16) and remove capacitor (15) .
3.
Remove screws (13), then take out carbon hold ers (10, 10 a).
4.
Remove screws (64), and take off shear head.
5. Unscrew screws (62) and remove in terme diate bearing (35).
6. Draw out pinio n (26). In case of th e damage of the pinion,
unscrew 3 screws (31) and remove armature pinion (30).
7. Draw grease re tain ing ring (9) out of the motor ho us in g (1),
loos en cy lindrical screws (8). and take out pole housing (6) .
8.
Dismantle eccentric axle (43).
9.
Remove shoe and take out plunger (41).
Re-assemble in reverse sequence.
Attention! Hits and blows on the fan wheel affect the good
ru nning conditions of the armature and should be avoided .
7.
Repair and Spare Parts
We recommend our Fein Servic e Stations to carry out all over-
haul and repair work quickly a nd expertly .
When ordering spare parts, please , quo te Order Reference or
send in sample part , stating the type of the ma ch in e.
We draw yo ur attention to th e n eed to carry out a high voltage
t est in accordance with your local regulations (or VDE reg ula-
tion 0740) before taking a tool in to service aft er any repair
carried out by your own staff.
