NOTE
If the diamond dry-cutting discs do not fit tightly, a
further 2 mm spacer disc must be fitted under the
washer.
wARNING
Risk of injuries due to cracking and breaking of
the diamond dry-cutting disc (bits of disc flying
around), caused by damaged, untrue running or
vibrating diamond dry-cutting discs.
Î
During the trial run of the machine, hold the
diamond dry-cutting discs away from your body
and do not touch or grip them.
Damaged, untrue running or vibrating diamond
dry-cutting discs must be replaced immediately.
•
Carry out a trial run of at least 30 seconds
without load.

Use an open-ended spanner size SQ13
to undo the hexagon nut (1) on the protective
hood (2).
•

Tighten the hexagon nut (1).
5.3 Connect dust extractor
•
Check the dust extractor to ensure that it is
working properly.
•
6
Push the dust extractor hose (3) firmly onto
the nozzle (2) of the protective hood (1).
NOTE
The nozzle (2) is designed to fit the suction hose
(3) of a MAKITA special dust extractor.
6
When the suction hose (3) is cold, a good deal
of effort is required to push it onto the nozzle (2) of
the diamond cutter.
5.4 Switch on the diamond cutter
and cut
•
7
Always hold the diamond cutter tightly with
both hands on the handles (2) / (6).
•
7
Position the front roller (1) on the wall – the
diamond dry-cutting discs must not touch the
wall.
•
7
Switch on the diamond cutter at the switch
(5) and wait until the working speed has been
reached – the green LED (3) lights up.
•
7
Plunge the diamond dry-cutting discs
uniformly into the wall – the green LED (3) must
not go out.
•
7
As soon as the rear roller (7) touches the
wall, the diamond cutter can be pushed in the
direction of the planned chase.

CAUTION
The diamond dry-cutting disc can become blunt or
damaged due to overheating. An overheated (blue
tarnished) diamond dry-cutting disc can usually no
longer be resharpened.
Î
The feed can only be as high as the diamond
dry-cutting disc can wear away the material.
Therefore, do not exert too large a force on the
diamond dry-cutting discs and avoid canting.
Note and follow the information and instructions
on handling diamond dry-cutting discs (see
page 74).
7
If the feed is too fast, the red LED (4) lights up.
Then, reduce the feed immediately until the green
LED (3) lights up again.
If this warning signal is ignored, i.e. the feed is not
reduced, the electronics switch off on overload.
DANGER
Risk of injury due to uncontrolled kickback of the
diamond cutter, caused by canting of the diamond
cutter in the cut chase.
Î
Always wait for the diamond dry-cutting discs to
stop completely before removing the diamond
cutter from the cut chase.
The cutting process can then be started and
continued as described above (see “Chap. 5.4
Switch on the diamond cutter and cut”).
