STIHL can supply a comprehensive
range of personal protective equipment.
Transporting the machine
Always stop the engine and attach the
chain scabbard.
Carry the machine only by the handlebar
– guide bar towards the rear – with the
hot muffler facing away from the body.
To avoid serious burn injuries, avoid
touching hot parts of the machine,
especially the surface of the muffler.
By vehicle: When transporting in a
vehicle, properly secure your machine to
prevent turnover, damage and fuel
spillage.
Refueling
Always shut off the engine before
refueling.
Do not fuel a hot engine – fuel may spill
and cause a fire!
Open the fuel cap carefully to allow any
pressure build-up in the tank to release
slowly and avoid fuel spillage.
Only refuel the machine in a well
ventilated place. If fuel has been spilled,
immediately clean the machine – do not
allow your clothes to be splashed with
fuel. If that happens, change your
clothes at once.
Dust may collect on the engine unit,
particularly around the carburetor. If dust
gets mixed with fuel – risk of fire. For this
reason, ensure that the dust is always
removed.
Bayonet-type fuel cap
Never use a tool to open or close the
bayonet-type fuel cap. This could
damage the cap and cause fuel to leak
out.
Close the bayonet-type fuel cap
carefully 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 behavior 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 User
Manual:
– Check the fuel system for leaks,
especially the visible parts, e. g.,
fuel 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 dealer
before commissioning
– Check operation of front hand guard
– Check the chain sprocket
– Sprocket nose moves easily
– Correctly mounted guide bar
Wear sturdy protective
gloves made of a resist-
ant material (e. g.
leather).
Gasoline is highly flam-
mable – keep away from
fire or flame – do not spill
any fuel – no smoking.
Check for fuel leakage!
Never start the engine if
fuel has been spilled or is
leaking – Fatal burns may
result!
