Fueling
Gasoline is an extremely
flammable fuel. Keep
clear of naked flames. Do
not spill any fuel – do not
smoke.
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.
Fuel your power tool only in well-
ventilated areas. If you spill fuel, wipe
the machine immediately – if fuel gets on
your clothing, change immediately.
Your power tool comes standard with
either a screw-type or bayonet-type fuel
cap.
After fueling, tighten
down the screw-type fuel
cap as securely as
possible.
Insert the fuel cap with
hinged grip (bayonet-type
cap) correctly in the
opening, turn it clockwise
as far as stop and fold the
grip down.
This reduces the risk of unit vibrations
causing the fuel cap to loosen or come
off and spill quantities of fuel.
To reduce the risk of serious or fatal
burn injuries, check for fuel leakage. If
fuel leak is found, do not start the
engine.

Before Starting
Check that your power tool is properly
assembled and in good condition – refer
to appropriate chapters in the instruction
manual.
Check the fuel system for leaks,
–
paying special attention to visible
parts such as the tank cap, hose
connections and the manual fuel
pump (on machines so equipped). If
there are any leaks or damage, do
not start the engine – risk of fire.
Have your machine repaired by a
servicing dealer before using it
again.
Engage the blade lock (if fitted).
–
Slide control / stop switch must
–
move easily to STOP or 0.
Smooth action of throttle trigger
–
lockout and throttle trigger – the
throttle trigger must return
automatically to the idle position.
Check that the spark plug boot is
–
secure – a loose boot may cause
arcing that could ignite leaking fuel-
air mixture and cause a fire.
Cutting blades securely mounted
–
and in good condition (clean, move
freely, not warped), properly
sharpened and thoroughly sprayed
with STIHL resin solvent (lubricant).
Check cutter guard (if fitted) for
–
damage.
Never attempt to modify the controls
–
or safety devices in any way.
Keep the handles dry and clean –
–
free from oil and dirt – for safe
control of the power tool.
To reduce the risk of accidents, operate
your power tool only if it is in a safe
condition.
Starting the Engine
Start the engine at least 3 meters from
the fueling spot, outdoors only.
Place the power tool on firm ground in
an open area. Make sure you have good
balance and secure footing. Hold the
power tool securely. The cutting blades
must be clear of the ground and all other
obstructions because they may begin to
run when the engine starts.
Your power tool is designed to be
operated by one person only. Do not
allow other persons in the work area –
even when starting.
To reduce the risk of injury, avoid
contact with the cutting blades.
Do not drop start the power tool – start
the engine as described in the
instruction manual.
Note that the cutting blades continue to
run for a short period after you let go of
the throttle trigger (flywheel effect).
Check idle speed setting: The cutting
blades must not move when the engine
is idling with the throttle trigger released.
Holding and Controlling the Power Tool
Always hold the power tool firmly with
both hands on the handles.
