Using the laser

 The laser enables you to make precision cuts with
your circular saw.

The laser light is generated by a laser diode. The
laser light is enlarged to form a line and is emitted
through the laser emission aperture. You can then
use this line as an optical marker for the sawing
line for precision cuts. Follow the laser safety
instructions.
 You can switch the laser ON and OFF with the
ON/OFF switch.
 The laser beam may be affected by deposits of
dust and chips. The emission aperture of the laser
beam must therefore be cleaned after each use.
 Always switch off the laser when not in use.
 Undo the screw for securing the saw blade by
turning it in clockwise direction with the Allen key
while at the same time holding on the opposite
side with another Allen key.
 Press the locking button (a) and use the lever to
raise the adjustable soleplate and hold.
 Remove the saw blade in a downwards direction.
 Clean the flange and insert the new saw blade.
Pay attention to the running direction (see arrow
on the housing and saw blade).

Tighten the screw to secure the saw blade, check
it runs true.
 Before you press the ON/OFF switch, make sure
that the saw blade is correctly fitted and that
moving parts run smoothly and the clamping
screws are lightened securely.
