5 Operation
5.1 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".
5.2 Switching on and off
•
Switching on: Press the switch-on lock 7 (Fig. 2)
forward to unlock it. Then, with the switch-on lock
depressed, press gearshift lever 8.
As this is a switch without locking device, the machine
will only run for as long as this gearshift lever is
pressed.
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.
Switch the machine off then. Then switch the machine
on again and continue sawing at a reduced feed
speed.
The setting wheel 20 (Fig. 2) can be used to adjust the
tool speed in a continuously variable manner between
2250 and 4400 rpm.

limits the saw blade slowing time to approx. 5 s.
The switch-on lock automatically takes effect
again and secures the portable circular saw
against accidental switch-on.
5.3 Cutting depth adjustment
The cutting depth is continuously variable between 0
and 88 mm.
Proceed as follows:
•
Press the push-button 11 (Fig. 1) and adjust the
cutting depth with the plunge lever 6.
•
The cutting depth can be read off scale 13 on the
cover. The surface of plunge lever 6 with the red
background serves as indicator.
5.4 Setting for bevel cuts
For bevel cuts, the saw unit can be set to any angle
between 0 °and 60°.
•
In order to incline it, bring the machine into home
position and support it such that it is possible to
tilt the saw unit.
•
Unfasten the wing nut 10 (Fig. 2)
•
Adjust the angle according to the scale on the
segment for tilting.
•
Afterwards, tighten the wing bolt 10.
5.5 Plunge cuts
•
Press the push-button 11 (Fig. 1) and put the
machine in the topmost position with plunge lever
6.

Always set the cutting depth
approx. 2 to 5 mm (5/64 to 13/64
in.) larger than the material
thickness to be cut.
Danger
Risk of backlash during plunge
cuts! Prior to plunging, place the
machine with the rear edge of its
base plate against a limit stop
fastened on the workpiece. Keep a
firm hold on the machine handle
during plunging and push the saw
lightly forward!
