Stihl GS 461, Instruction Manual

Page: 8 / 32

At the end of the cut, the concrete cutter is no
longer supported by the cutting attachment in the
cut. The user must bear the weight of the
machine – risk of loss of control!
Keep water and sludge away from alive electrical
cables – risk of electric shock!
2.11 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.
2.12 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! – Exception: adjust‐
ment of carburetor and idle speed.
To reduce the risk of fire due to ignition outside
the cylinder, move the slide control to STOP or 0
before turning the engine over on the starter with
the spark plug boot removed or the spark plug
unscrewed.
Do not service or store the machine near a
naked flame – risk of fire due to the fuel.
Check fuel cap regularly for tightness.
Use only spark plugs that are in perfect condition
and have been approved by STIHL – see "Speci‐
fications".
Inspect ignition lead (insulation in good condi‐
tion, secure connection).
Check that the muffler is in perfect working con‐
dition.
Do not use the machine if the muffler is damaged
or missing – risk of fire! – Hearing damage!
Never touch a hot muffler – risk of burns!
The condition of the antivibration elements influ‐
ences vibration behavior – inspect antivibration
elements periodically.
2.12.1
Switch off the engine
–
to check the chain tension
–
to retension the chain
–
to change chains
–
for remedying malfunctions
3 Sample Applications
Use diamond abrasive chain only with
water. Connect concrete cutter to
water supply network (min. 1.5 bar).
The water introduced is used to cool the dia‐
mond abrasive chain and rinse the cutting
attachment, and for binding dust.
After finishing work, run the concrete cutter for a
few seconds with water and at operating speed
to rinse the cutting attachment.
If the water pressure or water volume is too low,
this leads to significantly increased wear and
irreparable damage to the cutting attachment –
danger of breakage!
3.1 Objects to be cut
