In extreme working conditions, conductive dust
WARNING:
can accumulate inside the machine housing when working
with metal. This can result in the protective insulation inthe
machine becoming degraded with a potential risk of an
electrical shock.
To avoid build-up of metal swarf inside the machine, we recommend to clear
the ventilation slots on a daily basis. Refer to Maintenance.
Cutting Metal
For cutting with bonded abrasives, always use a protection guard
type 1.
When cutting, work with moderate feed, adapted to the material being cut.
Do not exert pressure onto the cutting disc, tilt or oscillate the machine.
Do not reduce the speed of running down cutting discs by applying sideward
pressure.
The machine must always work in an upgrinding motion. Otherwise, the
danger exists of it being pushed uncontrolled out of the cut.
When cutting profiles and square bar, it is best to start at the smallest cross
section.
Rough Grinding
Never use a cutting disc for roughing.
Always use the guard type 27.
The best roughing results are achieved when setting the machine at an angle
of 30° to 40°. Move the machine back and forth with moderate pressure. In
this manner, the workpiece will not become too hot, does not discolour and
no grooves are formed.
Cutting Stone
The machine shall be used only for dry cutting. For cutting stone, it is
best to use a diamond cutting disc. Operate the machine only with additional
dust protection mask.
Working Advice
Exercise caution when cutting slots in structural walls.
Slots in structural walls are subject to the country-specific regulations.
These regulations are to be observed under all circumstances. Before
beginning work, consult the responsible structural engineer, architect or the
construction supervisor.
Using Flap Discs
WARNING: Metal dust build-up.
in metal applications can result in the increased potential
for electric shock. To reduce this risk, insert an RCD before
use and clean the ventilation slots daily by blowing dry
compressed air into the ventilation slots inaccordance with
the below maintenance instructions.
