4.2. WORKING ADVICE
- Exercise caution when cutting slots in structural
walls; see Section "Information on Structures ".
- Clamp the workpiece if it does not remain stationary
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.
Cutting Metal
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.
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.
Cutting Stone
The machine may be used only for dry cutting/
grinding.
For cutting stone, it is best to use a diamond cutting
disc. 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.
For cutting expecially hard material, e. g., concrete
with high pebble content, the diamond cutting disc can
overheat and become damaged as a result. This is
clearly indicated by circular sparking, rotating with the
diamond cutting disc.
In this case, interrupt the cutting process and allow the
diamond cutting disc to cool by running the machine
for a short time at maximum speed with no load.
Noticeable decreasing work progress and circular
sparking are indications of a diamond cutting disc that
has become dull. Briefly cutting into abrasive material
(e. g. lime-sand brick) can resharpen the disc again.
Information on Structures
Slots in structural walls are subject to the Standard
DIN 1053 Part 1, or country-specific regulations.
Do not reduce the speed of running
down cutting discs by applying
sideward pressure.
The machine must always work in
an upgrinding
motion.
These regulations are to be observed under all
circumstances. Before beginning work, consult the
responsible structural engineer, architect or the
construction supervisor.
5_MAINTENANCE AND SERVICE
5.1. MAINTENANCE AND CLEANING
Before any work on the machine itself, pull the
mains plug.
For safe and proper working, always keep the
machine and ventilation slots clean.
In extreme working conditions, conductive dust
can accumulate in the interior of the machine when
working with metal. The protective insulation 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.
In all correspondence and spare parts order, please
always include article number given on the type plate
of the machine.
WARNING! Important instructions for connecting a
new 3- pin plug to the 2-wire cable.
The wires in the cable ar e coloured according to the
following code:
Do not connect the blue or brown wire to the earth
terminal of the plug. Important: If for any reason the
moulded plug is removed from the cable of this power
tool, it must be disposed of safely.
