• Tension the spring by continuing to turn the locking
sleeve. Skip three thread turns in the process. Then
release the lug on the locking sleeve. The locking
sleeve must not chafe on the driver of the clamping
lever when no saw blade is inserted.
• Finally, reinstall the base plate on the machine. See
chapter 4.6.
• Carry out a test cut.
6 Operation
6.1 Initial operation
Personnel entrusted to work with the machine must be
made aware of the operating instructions, calling
particular attention to the chapter "Safety instructions".
6.2 Switching on and off
For switching on and off, briefly actuate the switch
trigger 1 (Fig. 1).
The built-in electronic system provides for jerk-free
acceleration when the machine is switched on and
under load readjusts the speed to the fixed setting.
In addition, this electronic system adjusts the motor
down in case of overload, i.e. the saw blade will stop.
An acoustic warning signal is sounded. Switch the
machine off then. Then switch the machine on again
and continue sawing at a reduced feed speed.
With the setting wheel 4 (Fig. 1) you can continuously
adjust the stroke rate in 6 levels between 750 rpm and
3100 rpm.
Only switch on the machine with
fitted saw blade.
6.3 Pendulum stroke setting
The jig saw is equipped with a soft start, i.e. the
pendulum stroke only takes effect when pressure is
exerted on the saw blade. The degree of pendulum
movement is set with control lever 2 (Fig. 1) in two
levels. The pendulum stroke pushes the saw blade
against the workpiece during the working stroke and
lifts it off the workpiece during the downstroke. This
results in a favourable chip removal and a reduction of
the frictional heat.
If the switch is set to 0, the pendulum stroke is switched
off. For a faster work process, use levels 1 and 2.
You work without pendulum stroke:
• on thin material
• when working with rasp, tooth saw blade or knife
• on soft materials
• when cutting without predrilling for cut-outs in wood
• Reverse sawing
6.4 Splinter-free sawing
For splinter-free sawing on the surface of the material,
use the splinter guard included in the scope of supply
(see page 5, Item No. 205447, P-SS).
Danger
The machine must be switched off
before inserting the splinter guard.
• With the machine switched off, push the splinter
guard flush along the surface until just in front of the
saw blade (see Fig. I, P-SS).
• Switch on the machine.
• Press the machine with the splinter guard against a
stable edge to push in the splinter guard flush with
the front edge of the base plate, sawing into it in the
process. (Fig. II).
The use of pendulum stroke
positions 1 and 2 is advantageous
for the tearing behaviour on the
underside of the material.
6.5 Positioning the base plate
Once it has been released, the base plate can be
moved to the front and rear.
• Release the base plate as described under 5.7.
• Move the base plate into the desired position.
• Clamp the base plate as described under 5.7.
Possible base plate positions:
• Standard position for right-angled cuts, saw blade is
completely enclosed (Fig. 6).
• Base plate position is flush with the front edge of the
saw blade. This makes sawing close to the edge
possible (Fig. 7).
