Do not touch grinding and cutting discs until they have cooled down. The discs can become very
l
hot while working.
Flap Disc
English
With the flap disc (accessory), curved surfaces and profiles can be worked. Flap discs have a consider-
ably higher service life, lower noise levels and lower sanding temperatures than conventional sanding
sheets.
Rough grinding
English
Never use cutting discs for rough grinding.
l
The best rough grinding results are achieved with a set angle of 30° to 40°. Move the power tool back
and forth with moderate pressure. This will ensure that the workpiece does not become too hot or dis-
colour and that grooves are not formed.
Cutting Metal
English
Always use the protective guard for cutting (6) when cutting with bonded abrasives.
l
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.
Information on structural design
Slots in load-bearing walls are subject to DIN 1053 part 1 or country-specific regulations. These regula-
tions must be observed under all circumstances. Seek advice from the responsible structural engineer,
architect or construction supervisor before starting work.

Maintenance and Service

Pull the plug out of the socket before carrying out any work on the power tool.
l
To ensure safe and efficient operation, always keep the power tool and the ventilation slots clean.
l
In extreme conditions, always use a dust extractor if possible. Blow out ventilation slots fre-
l
quently and install a residual current device (RCD) upstream. When machining metals, conductive
dust can settle inside the power tool, which can affect its protective insulation.
Store and handle the accessories carefully.
In order to avoid safety hazards, if the power supply cord needs to be replaced, this must be done by
3M or by an after-sales service centre that is authorised to repair 3M power tools.

The power tool must always work in an up-grinding motion. Otherwise, there
is a risk that it will be pushed uncontrolled out of the cut. For best results
when cutting profiles and rectangular tubing, start at the smallest cross sec-
tion.
