Do not press down on the cut-off machine
Always decide the cutting direction before posi‐
tioning the cut-off machine. After that, do not
change the cutting direction. Never push or hit
with the device into the cutting gap – do not let
the concrete cutter fall into the cutting depth –
risk of breakage!
Diamond abrasive cutting wheels: If cutting per‐
formance begins to deteriorate, check the sharp‐
ness of the diamond abrasive wheel, resharpen
as needed. To do this, briefly cut through abra‐
sive material, e. g., sandstone, aerated concrete
or asphalt.
At the end of the cut, the cut-off machine is no
longer supported by the abrasive wheel in the
cut. The user has to absorb the weight force –
risk of loss of control!
When cutting steel: glowing metal
particles may cause fires!
Keep water and sludge away from alive electrical
cables – risk of electric shock!
Drag the abrasive wheel into the workpiece – do
not push it into the material. Do not correct
severing cuts with the cut-off machine. Do not re-
cut – remove left webs or breaking edges (for
example, with a hammer).
When applying diamond abrasive wheels, take a
wet cut – for example, use the STIHL water con‐
nector.
Depending on the version, composite resin abra‐
sive cutting wheels are suitable only for dry cut‐
ting or only for wet cutting.
When using composite resin abrasive cutting
wheels which are suited for wet cuts only, take
such wet cuts only – for example, use the STIHL
water connector.
When using composite resin abrasive cutting
wheels which are suited for dry cuts only, take
such dry cuts only. If however composite resin
abrasive cutting wheels of this type become wet,
their cutting performance is reduced and they
become dull. If composite resin abrasive cutting
wheels of this type become wet while working
(e. g., due to puddles or water in pipes), do not
increase the cutting pressure, but continue work‐
ing with the same pressure – risk of breakage!
Use up such composite resin abrasive cutting
wheels immediately.

Cutquik cart
Clear a path for the Cutquik cart. If the Cutquik
cart is pushed over objects, the abrasive wheel
may become wedged in the cut and shatter!
2.13
Vibrations
Prolonged use of the power tool may result in
vibration-induced circulation problems in the
hands (whitefinger disease).
No general recommendation can be given for the
length of usage because it depends on several
factors.
The period of usage is prolonged by:
–
Hand protection (wearing warm gloves)
–
Work breaks
The period of usage is shortened by:
–
Any personal tendency to suffer from poor cir‐
culation (symptoms: frequently cold fingers,
tingling sensations).
–
Low outside temperatures.
–
The force with which the handles are held (a
tight grip restricts circulation).
Continual and regular users should monitor
closely the condition of their hands and fingers. If
any of the above symptoms appear (e.g. tingling
sensation in fingers), seek medical advice.
2.14
Maintenance and repairs
The machine must be serviced regularly. Do not
attempt any maintenance or repair work not
described in the Instruction Manual. All other
work should be carried out by a servicing dealer.
STIHL recommends that maintenance and repair
work be carried out only by authorized STIHL
dealers. STIHL dealers receive regular training
and are supplied with technical information.
Use only high-quality spare parts. Otherwise,
there may be a risk of accidents or damage to
the machine. Contact a servicing dealer if in
doubt.
STIHL recommends the use of genuine STIHL
spare parts. Such parts have been optimized for
the machine and the user's requirements.
Before starting any maintenance or repair work
and before cleaning the machine, always stop
the engine – risk of injury!
To reduce the risk of fire due to ignition outside
the cylinder, move the stop switch to STOP or 0
before turning the engine over on the starter with
the spark plug boot removed or the spark plug
unscrewed.
