Operation

5.1 Initial operation

Personnel entrusted to work with the machine must
be made aware of the operating instructions, calling
particular attention
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.
On items No. 918202, 918230, 918231, 918232 and
918235, you can use the setting wheel 20 (Fig. 2) to
set the saw blade speed in a continuously variable
manner between 2250 and 4400 rpm.


Switching off: To switch off, release the
gearshift lever 8. The built-in automatic brake
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 (0 to 3 15/32 in.).
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.
Always set the cutting depth
approx. 2 to 5 mm (1/16 to 3/16 in.)
larger than the material thickness
to be cut.

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 screw 10 (Fig. 2).

Adjust the angle according to the scale on the
segment for tilting.

Afterwards, tighten the wing screw 10.

5.5 Plunge cuts

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!

Press the push-button 11 (Fig. 1) and put the
machine in the topmost position with plunge
lever 6.
