8.8 Limiting the cutting depth (Fig. 3, 16)
• The cutting depth can be infinitely adjusted using
the screw (30). To do this loosen the knurled nut
(30a) on the screw (30). Turn the screw (30) in or
out to set the required cutting depth. Then re-tight-
en the knurled nut (30a) on the screw (30).
• Check the setting by completing a test cut.
8.9 Sawdust bag (Fig. 1/20)
The saw is equipped with a debris bag (21) for saw-
dust and chips.
Attach the dust bag (21) to the outlet opening (21a).
The debris bag (17) can be emptied by means of a
zipper at the bottom.
8.10 Changing the saw blade (Fig. 1, 2, 17, 18)
Remove the power plug!
Important! Wear safety gloves when changing
the saw blade. Risk of injury!
• Swing the machine head (4) upwards and lock with
the safety pin (32).
• Loosen the Philips screw (e) two turns.
• Press the unlocking lever (3). Fold the saw blade
guard (5) up sufficiently that the flange screw (34)
is free.
• Firmly press the saw shaft lock (33) and slowly
rotate the flange bolt (34) in clockwise direction.
The saw shaft lock (33) engages after no more
than one rotation.
Attention! When loosening the screw, the ma-
chine head lowers slightly.
• Now, using a little more force, slacken the flange
bolt (34) in the clockwise direction.
• Turn the flange screw (34) right out and remove
the external flange.
• Take the blade (6) off the inner flange and pull out
downwards.
• Carefully clean the flange screw (34), outer flange
and inner flange.
• Fit and fasten the new saw blade (6) in reverse
order.
• Important! The cutting angle of the teeth, in other
words the direction of rotation of the saw blade (6)
must coincide with the direction of the arrow on
the housing.
• Before continuing your work make sure that all
safety devices are in good working condition.
• Important! Every time that you change the saw
blade (6), check to see that it spins freely in the
table insert (10) in both perpendicular and 45° an-
gle settings.
• Important! The work to change and align the saw
blade (6) must be carried out correctly.
8.11 Using the laser & LED - light (Fig. 2, 3)
• To switch on: Press the on / off switch for laser
& LED (28) 1x to switch on the laser. Press 2x to

• To switch off: Move the ON/OFF switch of the la-
ser & LED (28) 3 times.
8.12 Adjusting the laser (Fig. 3)
If the laser (8) ceases to indicate the correct cutting
line, you can readjust the laser. To do so, open the
screws (g) and set the laser by moving sideways to
that the laser beam strikes the teeth of the saw blade
(6).
9. Transport (Fig. 1, 2)
• Tighten the set screw (9) in order to lock the ro-
tary table (17)
• Activate the release lever (3), press the machine
head (4) downwards and secure with the safety pin
(32). The saw is now locked in its bottom position.
• Fix the saw's drag function with the locking screw
for drag guide (20) in rear position.
• Carry the equipment by the fixed saw table (18).
• When reassembling the equipment proceed as de-
scribed under section 7.

10. Maintenance

m Warning! Prior to any adjustment, maintenance or
service work disconnect the mains power plug!
General maintenance measures
Wipe chips and dust off the machine from time to
time using a cloth. In order to extend the service life
of the tool, oil the rotary parts once monthly. Do not
oil the motor.
When cleaning the plastic do not use corrosive prod-
ucts.
Brush inspection
Check the 2 carbon brushes (42) after the first 50
operating hours with a new machine, or when new
brushes have been fitted. After carrying out the first
check, repeat the check every 10 operating hours.
If the carbon is worn to a length of 6 mm, or if the
spring or contact wire are burned or damaged, it is
necessary to replace both brushes. If the brushes
are found to be usable following removal, it is pos-
sible to reinstall them.
