6 Operation

CAUTION
Observe nationally applicable regulations including,
for example, accident prevention regulations issued
by trade associations and regulations concerning the
general requirements to be met by workplaces on
construction sites.
6.1 Adjusting the cutting depth 2
1. Press the two depth adjustment buttons and hold
them in the pressed position.
2. Set the desired cutting depth according to the depth
scale.
3. Release the two depth adjustment buttons.
6.2 Slitting
CAUTION
When switching on, the machine must be in the start-
ing position. You may loose control of the machine if the
diamond discs are in contact with the material to be cut
when you switch the machine on.
1. Position the machine on the material in which the
slits are to be cut.
NOTE The cutting line pointer indicates the position
of the first diamond disc.
NOTE The working direction is indicated by the
cutting direction arrow.
2. Push the on/off switch to the side, press it in and
hold it in the pressed-in position.
3. Press the plunge movement lockbutton and hold it
in this position.
4. Apply reasonable pressure to the front grip of the
machine, causing the discs to plunge slowly into the
material to be cut until the preset cutting depth is
reached.
5. Guide the machine with both hands, applying reas-
onable pressure in the cutting direction.
NOTE Application of excessive pressure in the cut-
ting direction when slow cutting progress is made
may result in overheating and irreparable damage to
the diamond discs.
NOTE Application of excessive pressure in the cut-
ting direction when slow cutting progress is made
may cause the motor to stall.
6. Release the on/off switch if you wish to interrupt or
end the slitting operation.
7. DANGER After lifting the machine away from the
working surface, release the plunge movement
lockbutton. This will lock the parts of the machine
in their original starting position. Diamond cutting
discs that project from the machine present a risk of
injury.
Lift the machine away from the working surface
without pivoting or tilting it and then release the
plunge movement lockbutton.
6.3 Sharpening the diamond discs
CAUTION
Never hold the sharpening plate against the rotating
diamond cutting discs.
1. Lay the sharpening plate flat (not on its edge) on a
solid, flat surface (concrete) and secure it in position.
2. Set the machine to cut to a depth of 15 mm.
3. Hold the machine securely with both hands and
guide it towards the sharpening plate that is fixed in
position.
4. Make two to three cuts across the sharpening plate.

6.4 Working with the machine

Work in a downwards direction when making vertical
cuts.
Do not pivot or tilt the machine while guiding it.
NOTE
It is not possible to cut curves.
Select the right type of diamond disc for the material to
be cut.
If cutting performance drops, check whether the diamond
cutting discs are badly worn or if they need to be replaced
or sharpened.
