4.4 Replacing the saw blade

Danger
Pull the power plug during all
service work.
•
So as to fold down the saw guard cover 23 (Fig.3)
on the side, actuate push-button 2 (Fig. 4) and
pull locking lever 3 upwards. Pulling the locking
lever automatically locks the saw shaft and locks
the gearshift lever.
•
Using the Allen key 4 (brackets Fig. 2), unfasten
the flange screw 5 (Fig. 3) counter clockwise.
Remove the screw and the front clamping flange
6.
•
You can now remove the saw blade by lifting it to
the front.
•
The clamping flanges must be free of adhering
parts.
•
Pay attention to the sense of rotation when
inserting the saw blade.
•
Afterwards, mount the clamping flange, attach
the flange screw and tighten it by clockwise
turning.
•
Close the saw guard cover. To this end, close the
cover and press the locking lever 3 (Fig.3)
downwards.

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: First of all, unlock the switch-on
lock by pressing the locking lever 7 (Fig. 4). Then,
keeping the locking lever depressed, activate the
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.
Warming of the machine leads to faster overload
shutdown.
WIth the setting wheel 9 (Fig. 2) you can steplessly
adjust the saw speed between 3600 and 6250 rpm.

Switching off: To switch off, release the switch
trigger 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.
