Carry out a test run for at least one minute with no load.
Do not use damaged, out-of-centre or vibrating grinding
tools. Damaged grinding tools can burst and cause
injuries.
ON/ Off (SAB 900RPS)
For Start-up of power tool, push back the lock switch 10
and push the long switch 11, to disconnect the power
tool, release the long switch 11.

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.
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.
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.
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

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.

DISPOSAL
It is compulsory to subject electric tools, accessories
and packaging to a recovery process that respect the
environment.
For EU countries only:
Do not throw away electric tools!
In accordance with European Directive 2012/19/
UE on unserviceable electric and electronic
apparatus, after its transposition into national
