Pendulum action settings

The pendulum action can be adjusted using three different
settings, allowing the cutting speed, cutting capacity and the
cut itself to be optimally adapted to the material that you
want to cut.
You can also adjust the pendulum action during operation
using the adjusting lever 

(8)

.

Level 0

No pendulum action

Level 

Ⅰ

Low pendulum action

Level 

Ⅱ

High pendulum action

The optimum pendulum level for each application can be de-
termined by a practical test. Note the following recommend-
ations:
– Select a lower pendulum level or switch off the pendulum

action completely if you wish to produce a finer or cleaner
cutting edge.

– Switch off the pendulum action when machining thin ma-

terials (e.g. sheets).

– Work on hard materials (e.g. steel) with low pendulum ac-

tion.

– You can work on soft materials and saw wood in the direc-

tion of the grain using maximum pendulum action.

Adjusting the mitre/bevel angle (see figure H)

The base plate 

(9)

 can be swivelled to the right or left to

make mitre cuts up to 45°.
The extraction outlet 

(16)

 and anti-splinter guard 

(18)

 can-

not be used while mitre/bevel cuts are being made.
– Remove the extraction outlet 

(16)

 and the anti-splinter

guard 

(18)

.

– For mitre/bevel angle 0°, there is a pin in a corresponding

recess.

– Loosen the screw 

(23)

 with the hex key 

(24)

 until you can

slide the base plate 

(9)

 in towards the battery 

(1)

. Let the

pin slide into the guide groove.

– To adjust mitre/bevel angles, swivel the base plate 

(9)

 to

the required position according to the scale 

(25)

. Every

angle can be adjusted to 45° using a protractor.

– Retighten the screw 

(23)

.

Starting Operation

Inserting the battery
Note:

 The use of batteries unsuitable for your power tool can

lead to malfunctions or damage to the power tool.
Insert the charged battery 

(1)

 into the battery receptacle un-

til you feel it engage and it is securely locked in place.

Switching on the LED worklight

To switch the worklight 

(14)

 on or off, press the worklight

button 

(3)

.

u

Do not look directly into the worklight; it can blind
you.

Switching on/off

u

Make sure that you are able to press the On/Off switch
without releasing the handle.

To 

switch on

 the power tool, slide the on/off switch 

(7)

 for-

wards so that 

"I"

 appears on the switch.

To 

switch off

 the power tool, slide the on/off switch 

(7)

backwards so that 

"0"

 appears on the switch.

Restart protection

The restart protection feature prevents the power tool from
uncontrolled starting after the power supply to it has been
interrupted. Once the restart protection is active, the tem-
perature monitoring/overload protection indicator 

(6)

flashes continuously.
To restart the tool, set the on/off switch 

(7)

 to the off posi-

tion and then switch the power tool on again.

Note:

 Rapidly switching the power tool off and on again may

trigger the restart protection, meaning the power tool may
not start up even if the on/off switch 

(7)

 is pressed. Set the

on/off switch 

(7)

 to the off position and then switch the

power tool on again.

Preselect the stroke rate

You can also preselect the stroke rate and change it during
operation using the stroke rate preselection thumbwheel

(5)

.

The required stroke rate is dependent on the material and
the work conditions and can be determined using practical
tests.
It is recommended that you reduce the stroke rate when
placing the saw blade on the workpiece and when sawing
plastic and aluminium.
During prolonged periods of use at a low stroke rate, the
power tool may heat up significantly. Remove the saw blade
and let the power tool run at the maximum stroke rate for
around three minutes to cool down.

Temperature-dependent overload protection

In normal conditions of use, the power tool cannot be over-
loaded. If the power tool is overloaded or not kept within the
permitted battery temperature range, the speed is reduced
or the power tool switches off. At reduced speed, the power
tool will run again at full speed once the permitted battery
temperature is reached or the load is reduced. If it automat-
ically shuts down, switch the power tool off, allow the bat-
tery to cool down, then switch the power tool back on.

Temperature monitoring/overload protection indicator

The red temperature monitoring/overload protection indic-
ator 

(6)

 helps you to protect the battery against overheating

and the motor against overload.
If the temperature monitoring/overload protection indic-
ator 

(6)

 is lit up 

permanently in red

, the temperature of the

battery is too high and the power tool switches off automat-
ically.
Switch the power tool off and allow the battery to cool down
before you carry on working.
If the temperature monitoring/overload protection indic-
ator 

(6)

 is 

flashing

red

, then the power tool is blocked and

will switch off automatically.
