2. 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 without protective contact.
Switch must be in the "Off " position w hen connecting .
To prevent damage to the insulation no additional mar kin g plat-
es must be riveted or screwed to the casing. We recommend the
use of transfers only.
The machine performs quick and clean cuts when bla des are
inserted and adjusted in accordance with the instru ctions . Stops
or jams only occur when shear is wo rked in the wrong pos ition
and will be e limin at ed as soon as th e shear is brought in th e up-
right position. Do not use force!
If necessary switch off motor and restart cutting operation.
3. Setting and adjusting of cutter blades
Insert shoe blade (53) in groove of shoe and plunger b lad e (52)
in groov e of plunger. Fasten li g htl y with screws (68, 69). Do not
forget disc (44) and spring was h er (81). Turn set screw (45 ) until
the corners of blades at highest position of plunger are 0.4 mm
(0.2 in .) apart. Then fasten screw (68).
Adjust shoe blade in order to fit with sheet thickness by mea ns of
turning set screw (72) until the gap between blades is set for
sheet of 40 kp/mm at 0.7 mm (0.25 in.). When cutting thinner
sh eet than max. 3.5 mm (1. 5 in.) set gap at 0.2 mm (0.1 in.) x sheet
thickness. Then fasten screw (69). Turn scr ew (72) against shoe
blade.

The give n data are appro x imately. Control the correct setting of
the blades.
Attention ! Never work wi th blunt blades!
Remove blades for resharpening after unscrewing screws (68 ,
69). Do not forget disc (44) and spring washer ( 81 ). When shar-
pening , use plenty of coolant and observe cutting angles gi ven
in Fig. b and c. Control angle wit h gauge.
Attention! Do not cut we l ding sea ms.
No claims can be entertained for damage resulting from c utt ing
sheets of heavier gauge or high er strength than indicated or
working wit h blunt blad es.

Maintenance and lubrication
Before carrying out an y mainte nance work al w ays remember to
pull out the plug. Grease the machine daily at the lubricat ing
n
ipp le (83). To g reas e l et t he shear run at no loa d until clean
grease eme rges at the plunger.
After 300 duty hours clea n air openings of the mo t orhousi ng and
the motor by blowing out t he tool with dry pneumatic air or by
means of a brush. Rene w t he gear grease. Loosen screw (110)
and l ift off gear head . On ly use special gear grease Sst 1, 50 g
(1.8 oz) f
or gears (Ord er ref: MZ 60-3/Sst 1).
After 900 duty hours clean mac hin e thorough ly. Wash gears in
clean solvent and serve wit h fres h S st 1. Cl ean ball bearings an d
ser ve wit h fresh Sst 1 (lh of t he space bet ween inn er and ou ter
ring).

spare carbon brush

To dismantle tool see paragraph 5.
Clean electric parts only dry.
The carbon brushes should be replaced at the latest when they
have worn down to 7 mm (1 /•" ). For replacing see paragraph 5,
pos. 2. Please, only use original FEIN carbon brush es (Order Re-
ference EZ 11-67). After replacing carbon brushes make sure that
they are refitted in their original place and that they move easily
in their holder. After fitting new brushes, run tool unloaded for
about 15 minutes to allo w brushes to bed in. In order to prevent
accidents check cable at regular intervals. To replace the cable
see paragraph 5, pos. 3, 4.
One pair of spare carbon brushes will be found in th e handle;
please, do not forget to reorder them in time.
No claims can be entertained for damage due to negligent main-
tenance or inadequate lubrication .
5. Dismantling
The machine must only be taken apart by an expert.
1. Loosen screws (12) and remove cover (11).
2.
Clamp off carbon cable and pull out carbon brushes (5).
3.
Loosen screws (109, 115, 117). Take off bo w handle (left part
(108).
4. Clamp off cab le (96) from switch (100). Clamp off capacitor
(103) from motor housing (1).
5. Loosen screws (110), take off shear head (42) with intermediate
bearing (32) and take apart.
6. Remove securing ring (64), take off gear wheel (34) . Remove
securing ring (66). take out eccentric shaft (44).
7. Take off shoe (43), pull out plunger (39) .
8. Pull armature out of motor housing .
9. Pull air guiding ring (10) out of motor h ousing. Loosen screws
(9), take out pole housing (7).
Re-
assemble in reverse sequence.
6. Stationary use
Screw fixing de vic e (M 3-15-2) at shear hea d (42).
Attention! Do not clamp machine at shear head or bow handle.
7. Lubricant container
Fo r longer blade life keep cutting kerf well lu bricated . The lubri-
cant container (MZ 32-15-2) is working automatically. For use
screw container at shea r head. To reg u la te flow of lubrica nt turn
set screw.
8. Repair and Spare Parts
We recomm end our Fein Ser vice Stations to carry out all over -
haul and repair work quickly and expe rtl y.
When ordering spare parts, please, quote Order Reference or
send in sample part , stating the type of the machine.
We draw your attention to the need to ca rry out a high voltag e
test in accordance w ith your local regulations (or VDE regula -
t
ion 0740) before taking a tool into ser vi ce after any repair carri -
ed out by yo ur own staff.
P rior to work commencing, w hen work in g and when servicing
the machine always pay attention to the Regulations customary
in your Country.
