Starting Operation of the Power Tool
Observe correct mains voltage! The voltage
of the power source must agree with the
voltage specified on the nameplate of the
machine. Power tools marked with 230 V
can also be operated with 220 V.
Switching On and Off
To start the machine, press the On/Off switch 2.
To lock the On/Off switch 2, keep it depressed
and push the lock-on button 1 to the right or left.
To switch off the machine, release the On/Off
switch 2. When the On/Off switch 2 is locked,
press it first and then release it.
PST 700 PE/PST 700 PEL: After longer periods
of work at low stroke rate, the machine can heat
up considerably. Remove the saw blade from
the machine and allow the machine to cool
down by running it for approx. 3 minutes at max-
imum stroke rate.
Controling the Stroke Rate
(PST 700 PE/PST 700 PEL)
Increasing or reducing the pressure on the
On/Off switch 2 enables stepless stroke-rate
control of the switched-on machine.
When the On/Off switch 2 is locked, it is not
possible to reduce the stroke rate.
The required stroke rate is dependent on the
material and the working conditions and can be
determined by a practical trial.
Reducing the stroke rate is recommended when
the saw blade engages in the material as well as
when sawing plastic and aluminium.
Starting Opeation of the Laser Module
(PST 670 L/PST 700 PEL)
Do not point the laser beam at persons or
animals and do not look into the laser beam
yourself, not even from a large distance.
To switch the laser on, press the top of switch
13 ("on").
To switch the laser off, press the bottom of
switch 13 ("off").

The laser switches off automatically after an
operating period of approx. 10 minutes.

Working Advice

Laser Module (PST 670 L/PST 700 PEL)
Assembling the laser module 14 to the machine
is recommended when sawing alongside an al-
ready marked cutting line. Attach the laser mod-
ule onto the machine (see "Attaching/Removing
the Laser Module") and follow the marked cut-
ting line with the laser line while sawing.
When sawing under unfavourable conditions
(e.g. intense sun irradiation), the visibility of the
laser line can be improved when using the laser
viewing glasses 20 (accessory).
Plunge Cutting (see figures G–H)
Use only short saw blades for plunge cutting.
Plunge cutting is possible only with the mitre
angle set at 0°.
Place the machine with the front edge of the
base plate 5 on to the workpiece without the
saw blade 10 touching the workpiece and
Immediately switch the laser off again each
time after using. When handling the laser
module (separately or when mounted), one
can be blinded by the laser beam.
The laser module must be removed from the
power tool when used for stationary work
or when sawing from below a workpiece.
One can easily be blinded from the laser
beam when carrying out such work.
When working small or thin work pieces,
always use a sturdy support or a saw table
(accessory).
Do not use the laser viewing glasses as safe-
ty goggles. The laser viewing glasses are
used for improved visualisation of the laser
beam, but they do not protect against laser
radiation.
Do not use the laser viewing glasses as sun
glasses or in traffic. The laser viewing glass-
es do not afford complete UV protection and
reduce colour perception.
Plunge cuts may only be applied to soft
materials, such as wood, gypsum plaster
boards, etc.!
