additives (chromate, wood preservative). Materials contain-
ing asbestos may only be machined by specialists.
– Use a dust extraction system that is suitable for the ma-
terial wherever possible.
– Provide good ventilation at the workplace.
– It is advisable to wear a P2 filter class breathing mask.
The regulations on the material being machined that apply in
the country of use must be observed.
u
Avoid dust accumulation at the workplace.
Dust can
easily ignite.
Operation
Start-Up
u
Pay attention to the mains voltage. The voltage of the
power source must match the voltage specified on the
rating plate of the power tool. Power tools marked
with 230 V can also be operated with 220 V.
u
Products that are only sold in AUS and NZ:
Use a resid-
ual current device (RCD) with a nominal residual current
of 30 mA or less.
When operating the power tool using a mobile generator that
does not have sufficient reserve capacity or an adequate
voltage control system with inrush current boost converter,
loss of performance or atypical behaviour may occur upon
switch-on.
Please check the suitability of the power generator you are
using, particularly with regard to the mains voltage and fre-
quency.
u
Hold the tool by the insulated gripping surfaces and
auxiliary handle only.
The application tool could come
into contact with hidden wiring or its own cord.
Con-
tact with live wires may make metal parts of the tool live,
posing a risk of electric shock.
Switching on/off
To
start
the power tool, push the on/off switch
(4)
forward.
To
lock
the on/off switch
(4)
in position, push the on/off
switch
(4)
forward and down until it clicks into place.
To
switch off
the power tool, release the on/off switch
(4)
;
or, if the switch is locked, briefly push the on/off switch
(4)
backward and down and then release it.
u
Always check abrasive tools before using them. The
abrasive tool must be fitted properly and be able to
move freely. Carry out a test run for at least one
minute with no load. Do not use abrasive tools that are
damaged, run untrue or vibrate during use.
Damaged
abrasive tools can burst apart and cause injuries.
Restart protection
The restart protection feature prevents the power tool from
uncontrolled starting after the power supply to it has been
interrupted.
To
restart
the tool, set the on/off switch
(4)
to the off posi-
tion and then switch the power tool on again.
Working advice
u
Pull the plug out of the socket before carrying out any
work on the power tool.
u
Exercise caution when cutting slots in structural walls;
see the "Information on structural design" section.
u
Clamp the workpiece if it is not secure under its own
weight.
u
Do not load the power tool so heavily that it comes to a
stop.
u
If the power tool has been subjected to a heavy load,
continue to run it at no-load for several minutes to
cool down the accessory.
u
Do not use the power tool with a cut-off stand.
u
Do not touch grinding and cutting discs until they have
cooled down.
The discs can become very hot while work-
ing.
Rough grinding
u
Never use cutting discs for rough grinding.
The best rough grinding results are achieved with a set angle
of 30° to 40°. Move the power tool back and forth with mod-
erate pressure. This will ensure that the workpiece does not
become too hot or discolour and that grooves are not
formed.
Flap Disc
With the flap disc (accessory), curved surfaces and profiles
can be worked. Flap discs have a considerably higher ser-
vice life, lower noise levels and lower sanding temperatures
than conventional sanding sheets.
Cutting Metal
u
Always use the protective guard for cutting (8) when
cutting bonded abrasives.
When carrying out abrasive cutting, use a moderate feed
that is suited to the material being machined. Do not exert
pressure on the cutting disc and do not tilt or swing the
power tool.
Do not attempt to reduce the speed of a cutting disc coming
to a stop by applying pressure from the side.
The power tool must always
work in an up-grinding mo-
tion. Otherwise, there is a
risk that it will be pushed
uncontrolled
out of the cut.
For best results when cut-
ting profiles and rectangular
tubing, start at the smallest
cross section.
Cutting stone
u
Provide sufficient dust extraction when cutting stone.
u
Wear a dust mask.
u
The power tool may be used only for dry cutting/grind-
ing.
