Dust Extraction

Dust developing while working can be harmful to
one's health, combustible or explosive.
The machine must be connected to a suitable extraction
system (vacuum cleaner). The vacuum cleaner must be
suitable for the material to be worked.
For extraction of carcinogenic, dry dusts that are par-
ticularly hazardous to one's health, a special vacuum
cleaner is to be used. The vacuum connection (1) fits a
vacuum hose with a diameter of 35 mm.
To ensure optimum dust extraction and prolong the
service life of the routing tool, clean the extraction
channels regularly.
Starting and Operation
Ensure that the voltage of the power supply matches
the information on the type plate of the power tool.
Tools with a rating of 230 V can also be connected to a
220 V/240 V supply.
Auxiliary Handle
The enclosed auxiliary handle (8) is to be fastened at
one of the two attachment points (bolt hole)(12) of the
retaining bracket (9) (see main figure).
It is to be used at all times for safety-technical reasons
and improves the handling of the machine.
Suspension Eyelet
The machine is equipped with a suspension eyelet (10)
for use with a balancer. Due to the weight relief,
fatigue-free working is enabled (e.g. on facades and
walls).
Adjusting the Depth-of-Cut
Loosen the adjustment knob (11). By turning the base
plate, the depth-of-cut or the thickness of material
removal respectively, can be removed within the range
of 0 – 3.5 mm (see main figure):
Turning in clockwise direction = increases the depth-
of-cut
Turning in counterclockwise direction = reduces the
depth-of-cut
The adjustment of the depth-of-cut depends on the
material to be removed and the grinding tool being
used. For extreme hard materials, perform several
work steps with reduced depth-of-cut.
Switching on and off
Press the unlocking lever (4) forward to release the on-
off switch lever (3). At the same time, press the on-off
switch lever (3) to start the machine operation and
release it to stop.
Continuous use
Press the unlocking lever (4) forward to release the on-
off switch lever (3). At the same time, press the on-off
switch lever (3) to the stop and press the unlocking
lever (4) completely forward.
To switch off continuous operotion, press and release
the on-off switch (3) again..

Electronic Motor Control

Starting current limiting
The electronically controlled smooth start takes care
that the machine starts without jerk. As a result of the
machine's reduced starting current, a 16 A fuse is suf-
ficient
Electronic speed pre-selection
The required speed can be pre-selected with the speed
selector thumbwheel (7) (also possible during opera-
tion).
Speed 1: 1000 rpm Speed 4: 1700 rpm
Speed 2: 1300 rpm Speed 5: 2000 rpm
Speed 3: 1500 rpm Speed 6: 2200 rpm
The required speed depends on the material being
machined and can be determined by trial (see applica-
tion table).
When putting a high load on the machine, always set
the speed selector thumbwheel (7) to the maximum
speed.
After long periods at low operating speed, run the drill
at high speed and without load for approx. 3 minutes,
in order to cool the machine down.
Constant-Electronic
The constant-electronic keeps the speed almost con-
stant at no-load and under load; this ensures constant
work feed and uniform material removal.
Electronic overload protection
In case that the machine is extremely overloaded, an
electronic overload protection protects the motor from
damage. In this case, the motor stops and restarts only
after the feeding pressure is reduced, res. after relief.
Temperature-dependent overload pro-
tection
To protect the motor from overheating at extreme per-
manent load, it is switched off by the protective elec-
tronic system when a critical temperature is reached.
After a cooling-down period of approx. 3 - 5 min., the
machine is again ready for use and can be fully loaded.
When the machine is warmed by use, the temperature-
dependent overload protection reacts earlier as a result.
