QSz 736 (42 V)
2. 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 ro tects the
operator against electric accidents which may be caused by de-
fects in the normal insulation . The pole housing is insulat ed 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 pre sc ribed 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.
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 c uts when blades are in-
serted a~d adj usted in accordance with the instru ctions. 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 to uch in the right position. Use no force!
If necessary switch off motor a nd restart cutting opera tion.
4. Maintenance and Lubrication
Before carryi ng out any maintenance work always remember to
pull out the plug .
Every 100 duty hours the tool should be . cleaned thoro ughly in
order to guarantee the safet y given by the protec tiv e insulation.
For thi s purpose carbon holders and insul ated par ts must be
cleaned of carbon and grinding dust. This is done by means of a
brush or by blowing o ut the t ool with dry pne um atic air or a
hand blower.
For checking the carbon brushes the carbon holde rs (10) can be
taken out after unscre w ing the screws (12). Make sure that the
carbon brus h es are refitt ed in t heir original place a nd that th ey
mo ve easily in their holder. They should be replaced at the
latest when they have worn down to 7 mm (1 / 4" ). Please, onl y
.
use original Fein carbon br u she s (Order Reference EZ 11-62).
After fit ting , new brush es, run tool unloaded for abo ut 15 minu-
tes to allow brush es 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 regula r intervals.
To re place the cable unscre w th e screws (22) and (2 3) and re -
mo ve the cover (21) . Clamp off cab le from switch (14), unscrew
screws (20) at cabl e clamping bridge (1 9) and ta ke out cab le.
Use Universal Grease type Sst 1
instead of other types of grease!

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
FK 3 (tube of approx. 10 g C/3 oz), Order Reference: MZ 60-2/
FK 3).
No claims can be entertained for damage due to negligent main-
tenance and inadequate lubrication.
The shear head being the power transmitting element requires a
good lubrication. It is recommended to renew the gear grease
after approximately 300 working hours. Please only use special
FEIN gear grease FG 12. A mixing of this grease with other
greases endangers the greasing capacities and therefore also
use FG 12 grease for the roller bearings in the shear head. After
about 50 working hours regrease the plunger guide by the
lubricating nipple (74).
Attention!
Never work with blunt blades! For resharpening the blades,
they can be removed after unscrewing the two screws. When
sharpening, use plenty of coolant and strictl y observe the pre-
scribed cutting angles. If blades are resharpened in time, break-
ing out is avoided.
Attention! Do not cut welding seams

Fitting and adjusting of the blades
Insert fixed blade (49) and plunger blade (48) and secure slightly
with screws (67, 68). Turn set screw (46) until the corners of the
blades at highest plunger position overcross at about 0.6 mm
(0.2 in) (Dimension F). Screw and plunger blade should then be
t ightened.
L
lowest position
Hereafter the fixed blade should finally be adjusted by set
screw (71) so that the gap "L" is 1110 of the sheet thickness to
be cut. (e. g. sheet metal of 2 mm thickness- 0.2 mm).

the following sequence:
1. Unscrew screws (22) . and (23) and remove motor housing
cover (21).
2. Clamp off connections to pol e housing (6), capacitor (15) and
cable (17) at switch (14) and take out switch. Unscrew sc re w
(16) and remove capacitor (15) .
3. Remove screws (12), then take out carbon holder (10).
4. Remove screws (77, 79) and take off shear head.
5. Unscrew scre ws (76) and remove intermediate bearing. Take
out gr ease retaining ring (9) and armature (26).
Attention! To maintain true running conditions never us e
force.
6. Unscrew screw (47), take off gear wheel (57) and remove
securing ring (72).
7. Dismantle eccentric shaft (44).
8. Remove shoe and take out plunger (40).
Re-assembl e in reverse sequ e nce .
6. Repair and Spare Parts
We recommend our Fein Service Stations to carry out all over-
haul and repair work quickly and expertly.
When ord e ring spare parts, please, quote Order Ref erence or
send in sample p art, stating the type of the machine.
We draw yo ur attention to th e n ee d to carry out a high voltage
test in accordance with your local regulations (or VDE regula-
tion 0740) before taking a tool into service after any repair carri-
ed out by your own staff.
