2.3
Refueling
Gasoline is highly flammable – keep
away from fire or flame – do not spill
any fuel – no smoking.
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.
After refueling, close the fuel cap as
tightly as possible.
This helps reduce the risk of unit vibrations caus‐
ing an incorrectly tightened fuel cap to loosen or
come off and spill quantities of fuel.
Check for leaks. Do not start the engine if there
is a fuel leak – serious or fatal burns could result!
2.4
Before starting
Check that your power tool is properly assem‐
bled 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
using it
–
The stop switch must be easy to push
–
Check the rotary knob for warm start, throttle
trigger lockout, throttle trigger and set wheel
for smooth action – the throttle trigger must
return automatically to idle position. From the
warm start knob position
g
, it must return to
the run position
F
when the throttle trigger
lockout and throttle trigger are pressed simul‐
taneously
–
Check that the spark plug boot is secure – a
loose boot may cause sparking that could
ignite combustible fumes and cause a fire!
–
Cutting blades must be properly tightened and
in safe operating condition (clean, sharp, not
bent or warped), correctly mounted and thor‐
oughly sprayed with STIHL resin solvent (lubri‐
cant)
–
For machines with adjustable cutter bar: The
adjustment mechanism must be snapped into
the start position
–
For machines with a defined transport position
(cutter bar folded against the shaft): Never
start the machine in the transport position
–
Never attempt to modify the controls or safety
devices.
–
Keep the handles dry and clean – free from oil
and dirt – this is important for safe control of
the machine
–
Adjust carrying harness and handles in
accordance with body height. Observe the
chapter "Fitting the Harness"
To reduce the risk of personal injury, do not
operate your power tool if it is damaged or not
properly assembled!
To prepare for emergencies when using a har‐
ness: Practice setting down the machine quickly.
To avoid damage, do not throw the machine to
the ground when practicing.
2.5
Starting the engine
Start the engine at least 3 meters from the fuel‐
ing 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.
Avoid contact with the cutting blades – risk of
injury!
Do not drop-start the engine – start it as descri‐
bed in the User Manual. Note that the cutting
blades continue to run for a short period after
you let go of the throttle trigger (flywheel effect).
Check engine idling: The cutting blades must
remain at a standstill when the engine idles –
throttle trigger released.
Keep easily combustible materials (e.g., wood
chips, bark, dry grass, fuel) away from hot
exhaust gases and the hot muffler surface – risk
of fire!
