2 Safety Precautions and Working Techniques
– Dispose of residual chemicals and used con‐
tainers in accordance with local waste dis‐
posal regulations
2.6
Transporting the machine
Always stop the engine.
Transporting in a vehicle:
– Secure the machine against overturning, dam‐
age and fuel spillage
– The container must be empty and clean
2.7
Refueling
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.
Always remove the power tool from your back
and put it on the ground before refueling. Fuel
the unit only when it is standing securely on the
ground.
Open the fuel cap carefully to allow any pressure
build-up in the tank to release slowly and to pre‐
vent fuel spraying out.
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.
Check for fuel leakage! Never start
the engine if fuel has been spilled or
is leaking – Fatal burns may result!
Fuel cap
After fueling, tighten down the screw-
type fuel cap as securely 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.
2.8
Before starting
Check that your power tool is properly assem‐
bled and in good condition, especially if it has
been subjected to unusually high loads for which
it was not designed (e.g. heavy impact or a fall).
– Check the fuel system for leaks, especially the
visible parts, e. g., fuel cap, hose connections,
manual fuel pump (only in machines with a
0458-450-8721-C
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 setting lever must move easily to STOP or
0
– Throttle trigger must move freely and spring
back by itself to the idle position
– Check that the spark plug boot is secure – a
loose boot may cause sparking that could
ignite combustible fumes and cause a fire!
– Check the fuel system for leaks
– Check the condition and tightness of con‐
tainer, hose and metering unit
– Check condition of harness straps and replace
damaged or worn straps
To reduce the risk of accidents and personal
injury, do not operate your power tool if it is not
properly assembled and in good condition.
For emergencies: Practice quickly opening the
fastener on the waist belt (special accessory),
loosening the shoulder straps and setting down
the unit. To avoid damage, do not throw the unit
to the ground when practicing.
2.9
Starting the engine
Start the engine at least 3 meters from the fuel‐
ing spot, outdoors only.
Your power tool is designed to be operated by
one person only. Do not allow other persons in
the work area – even when starting.
Always proceed as described in the user manual.
Place the machine on level ground only, ensure
that you have a secure footing and hold the
machine securely.
If an assistant is required to put the power tool
on your back, make sure that
– the engine is running at idle speed
– the assistant is not standing in the area of the
exhaust outlet and breathing exhaust fumes
– the valve lever is closed
