Stihl GS 461 Instruction Manual page 9

Do not allow the guide bar to
–
become jammed
Always be aware that the object to
–
be cut may move and other factors
may cause the cut to close and jam
the diamond abrasive chain
The object to be cut must be
–
secured and supported so that the
cut remains open during and after
cutting
Do not twist the guide bar in the cut
–
Working – parting-off grinding
Ensure sufficient water supply to
diamond abrasive chain – do not allow
diamond abrasive chain to run dry.
Always wet cut – regardless of the
material to be cut.
The diamond abrasive chain must be
guided straight in the cut, without
wedging. Never exert lateral pressure on
the diamond abrasive chain.
Do not use for lateral grinding or
scrubbing.
Do not use the starting throttle position
for cutting. Engine speed cannot be
controlled with the throttle trigger in this
position.
GS 461
Check the work area. Avoid danger due
to damage to pipes and electric power
lines.
The machine must not be used in the
vicinity of flammable substances and
combustible gases.
Do not cut into pipes, metal tanks or
other containers if you are not sure that
they do not contain any volatile or
inflammable substances.
Never leave the machine unattended
with the engine running. Stop the engine
before leaving the machine unattended
(e. g. for breaks).
Work calmly and carefully – in daylight
conditions and only when visibility is
good. Do not endanger others – stay
alert at all times.
Make certain that all parts of your body
are well clear of the extended range of
travel of the diamond abrasive chain.
Only pull concrete cutter out of the
object being cut with the diamond
abrasive chain running.
Only use concrete cutter for cutting – not
for prying or shoveling away objects.
Always decide the cutting direction
before positioning the concrete cutter.
Do not change the cutting direction.
Never push or hit with the device into the
cutting gap – do not let the parting-off
grinder fall into the cutting depth – risk of
breakage!
If cutting performance begins to
deteriorate, check the sharpness of the
diamond abrasive chain, resharpen as
needed. To do this, briefly cut through
abrasive material, e. g., sandstone,
aerated concrete or asphalt.
When working at heights:
Always use a lift bucket
–
Never use the machine while
–
standing on a ladder
Never use the machine in unsteady
–
locations
Never cut above shoulder height
–
Never use the machine with one
–
hand
Begin cutting with the concrete cutter at
full throttle.
At the end of the cut, the concrete cutter
is no longer supported by the cutting
attachment in the cut. The machine's
weight must be borne by the user – risk
of loss of control!
Keep water and sludge away from alive
electrical cables – risk of electric shock!
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.
