Stihl GS 461 Instruction Manual page 6

English
If fumes or smoke are anticipated (e. g.,
when cutting composite materials), wear
respiratory protection.
Wear sturdy protective
gloves made of a resist-
ant material (e. g.
leather).
STIHL can supply a comprehensive
range of personal protective clothing
and equipment.
Transporting the machine
Always stop the engine and attach the
chain scabbard.
Carry the machine only by the top
handle – guide bar towards the rear –
with the hot muffler facing away from the
body.
Do not touch hot device parts, in
particular the muffler surface – risk of
burns!
In vehicles: Properly secure the machine
to prevent turnover, fuel spillage and
damage.
Refuelling
Petrol is an extremely
flammable fuel – keep
clear of naked flames and
fire – do not spill any fuel
– no smoking.
Switch off the engine before refuelling.
Never refuel the machine while the
engine is still hot – the fuel may spill over
– risk of fire!
4
Open the fuel filler cap carefully so that
any excess pressure is relieved
gradually and fuel does not splash out.
The machine may only be refuelled in a
well ventilated place. If fuel has been
spilled, clean immediately the engine-
driven device – prevent your clothes
from being contaminated with fuel,
otherwise change clothes at once.
Dust may collect on the engine unit,
especially around the carburetor. If dust
gets mixed with fuel – risk of fire!
Remove the dust from the engine unit
regularly.
Look out for leaks! Never
start the engine if fuel has
been spilled or is leaking
– Fatal burns may result!
Bayonet filler cap
Never use a tool to open or close the
bayonet filler cap. The cap can be
damaged and fuel may escape.
Secure the bayonet filler cap tightly after
refueling.
Diamond abrasive chain
The diamond abrasive chain, guide bar
and chain sprocket must match each
other and your concrete cutter.
Use only approved diamond abrasive
chains. If unauthorized chains are used,
aggressive cutting cannot be ruled out.
This may lead to uncontrolled and
exceedingly dangerous reaction forces
(kickback) in the machine – risk of fatal
injuries!
Only use diamond abrasive chain for the
specified materials, observe diamond
abrasive chain codes.
Always cut with water.
Before fitting used diamond abrasive
chains, check that they are not cracked,
chipped, check also that there are no
damaged or missing segments, signs of
overheating (discoloration).
Never use diamond abrasive chains that
are cracked or have chipped segments.
Contact your servicing dealer.
Before starting
Check that concrete cutter is properly
assembled and in good condition – refer
to appropriate chapters in the Instruction
Manual:
Check the fuel system for leaks,
–
especially the visible parts, e. g.,
filler cap, hose connections, manual
fuel pump (only in machines with a
manual fuel pump). In case of
leakage and damage, do not start
the engine – risk of fire! Have the
machine serviced by a servicing
dealer before using it.
