Operation
Switching On and Off
EN
Caution! Before switching on the sabre jig saw,
the dust cover 3 in front of the tappet must be low-
ered again to the saw bench 4.
 To switch on the device, slide the circuit clos-
er/breaker 1 to the front.
 Pressing the swung-out front edge of the cir-
cuit closer/breaker 1 will move it back to the
Off position.
Restarting protection
The restarting protection feature pre-
vents uncontrolled restarting of the
machine after an interruption in the
power supply.
 To restart the operation, switch the On/Off
switch 1 to the Off position and start the ma-
chine again.
Pendulum stroke setting
The change-over from the setting 0-3 is effected
by means of the pendulum-stroke adjusting knob
7 (turning knob). The mark indicates the pendu-
lum stroke selected.
Recommendations for pendulum stroke settings
Pos. 0 for glass, ceramics, soft steel, non-
ferrous metals, aluminium and pres-
sed materials
Pos. 1 for plastics
Pos. 2 for plywood
Pos. 3 for hardwood, softtextured wood,
chipboard
It should be noted that the values given are stan-
dard values which may vary according to thick-
ness and hardness of material, grain direction,
and also to the condition of the saw blade.
The optimal orbital action setting for the respec-
tive application can be determined through practi-
cal testing. The following recommendations apply:
 Select a lower orbital action setting (or switch
it off) for a finer and cleaner cutting edge.
 For thin materials such as sheet metal, switch
the orbital action off.
 For hard materials such as steel, work with
low orbital action.
 For soft materials and when sawing in the di-
SPS-EN / 0912
rection of the grain, work with maximum orbit-
al action.
Miter cuts up to 45°
Turn the stop lever 10 90° to release the saw
bench 4 at the front. You can now push the saw
bench 4 to the back (towards the suction connec-
tion piece) and bring it into the desired tilted posi-
tion. Turn the stop lever 10 back to lock the tilted
position.
You may need to regulate the tension by turning
the lever 10 forwards again and tightening the ten-
sion wheel by turning it clockwise.
Turn the lever 10 back to lock the saw bench 4 into
position. The angles 15°, 30° and 45° can be se-
curely locked into place on the saw bench 4.
Setting for rectangular cuts in 0° posi-
tion (vertical saw blade)
Turn the stop lever 10 90° to release the saw
bench 4 at the front. Then the saw bench 4 can if
necessary be released from the notches by pulling
it backwards, then rotated into the 0° position and
locked in again. Lock the position of the saw
bench 4 by turning the lever 10 back.
You may need to regulate the tension by turning
the lever 10 forwards again and tightening the ten-
sion wheel by turning it clockwise. Turn the lever
10 back to lock the saw bench 4 into position.
Sliding block
To prevent the workpiece surface from being
scratched, attach the sliding block 14 onto the saw
bench 4 from the front.
Chip tearing protection
Depending on the intended use, one of the two
means of stress corrosion protection can be used
as follows:
for the saw bench 4
the plastic part 13 is pressed into the saw opening
of the saw bench 4 from underneath (snaps into
place).
for the sliding block 14
the sliding block 14 is attached on the saw bench
4 from the front, together with the steel part 15 in-
serted from the top into the saw opening.
