INSTRUCTIONS FOR USE
Exercise caution when cutting slots in structural
walls; see Section "Information on Structures ".
Clamp the workpiece if it does not remain statio-
nary due to its own weight.
Do not strain the machine so heavily that it comes
to a standstill.
Grinding and cutting discs become very hot while
working; do not touch until they have cooled.
Rough Grinding
Never use a cutting disc for roughing.
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.
Flap Disc
With the flap disc (accessory), curved surfaces and
profiles can be worked. Flap discs have a considerably
higher service life, lower noise levels and lower
sanding temperatures than conventional sanding
sheets.
Cutting Metal
For cutting metal, always work with the protection
guard for cutting 7.
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.
For cutting stone, it is best to use a diamond cu-
tting disc. As a safety measure against jamming,
the cutting guide with dust extraction protection
guard must be used.
Operate the machine only with dust extraction
and additionally wear a dust protection mask. The
vacuum cleaner must be approved for the extraction
of masonry dust. STAYER provides suitable vacuum
cleaners and suction casing.
The machine must always work
in an up-grinding 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.
The machine may be used only
for dry cutting/grinding.
Switch on the machine and place
the front part of the cutting guide on
the workpiece.
Slide the machine with moderate
feed, adapted to the material to be
worked.

4_MAINTENANCE INSTRUCTIONS

Cleaning, maintaining, lubricating, sharpening
Before any work on the machine itself, pull the
mains plug.
For safe and proper working, always keep the ma-
chine and ventilation slots clean.
In extreme working conditions, conductive dust
can accumulate in the interior of the machine
when working with metal. The protective insula-
tion of the machine can be degraded. The use of
a stationary extraction system is recommended in
such cases as well as frequently blowing out the
ventilation slots and installing a residual current
device (RCD).
Please store and handle the accessory(-ies) carefully.
If the machine should fail despite the care taken in
manufacturing and testing procedures, repair should
be carried out by an after-sales service centre for
STAYER power tools.
