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 locking bolt (23).
• Loosen the retaining screw (5a) of the cover using a
Philips screwdriver.
WARNING! Do not fully remove this screw.
• Fold the saw blade guard (5) upwards until the saw
blade guard (5) is above the flange screw (28).
• With one hand insert the Allen key (C) in the flange
screw (29).
• Hold the Allen key (C) and slowly close the saw
blade guard (5) until it touches the Allen key (C).
• Firmly press the saw shaft lock (30) and slowly ro-
tate the flange screw (28) in clockwise direction.
The saw shaft lock (30) engages after no more than
one rotation.
• Now, using a little more force, slacken the flange
screw (29) in the clockwise direction.
• Turn the flange screw (28) right out and remove the
outer flange (29).
• Take the blade (6) off the inner flange (31) and pull
out downwards.
• Carefully clean the flange screw (28), outer flange
(29) and inner flange (32).
• Fit and fasten the new saw blade (6) in reverse or-
der.
• 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 safe-
ty 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 ta-
ble insert (10) in both perpendicular and 45° angle
settings.
• Important! The work to change and align the saw
blade (6) must be carried out correctly.

8.12 Adjusting the laser (fig. 19-20)
If the laser (32) ceases to indicate the correct cutting
line, you can readjust the laser. To do so, open the
screws (32b) and remove the front cover (32a). Loos-
en the Philips head screws (E) and set the laser by
moving sideways until the laser beam strikes the teeth
of the saw blade (6).
After adjusting and tightening the laser, mount the
front cover by tightening both screws (32b) by hand.

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 us-
ing 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 products.
Cleaning the moving saw blade guard safety
device (5)
Always check the saw blade guard for debris before
using the machine.
Remove old sawdust and splinters using a brush or
similar tool.
Replacing the table insert
Danger!
• With a damaged table insert (10) there is a risk of
small parts getting stuck between table insert and
saw blade, blocking the saw blade.
Immediately replace damaged table inserts!
1. Remove screws at table insert. If required, turn ro-
tary table and incline saw head to be able to reach
the screws.
2. Remove table insert.
3. Install new table insert.
4. Tighten the screws at table insert.
Brush inspection
Check the carbon brushes 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 possible to
reinstall them.
