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 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.
Check for fuel leakage! Never start
the engine if fuel has been spilled or
is leaking – Fatal burns may result!
2.4 Before starting
Check that your power tool is properly assem‐
bled and in good condition – refer to appropriate
chapters in the instructions for use.
– 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
– Functional drill brake
– Check the choke lever, throttle trigger and
throttle trigger lockout for smooth action -
throttle trigger must return automatically to idle
position. The choke lever must spring back
from the g and < positions to the run posi‐
tion F when the throttle trigger lockout and
throttle trigger are squeezed
– Check that the spark plug boot is secure – a
loose boot may cause arcing that could ignite
combustible fumes and cause a fire!
– Never attempt to modify the controls or safety
devices

2 Safety Precautions and Working Techniques
– Keep the handles dry and clean – free from oil
and dirt – this is important for safe control of
the machine
To reduce the risk of personal injury, do not
operate your power tool if it is damaged or not
properly assembled!
2.5 Starting the engine
Start the engine at least 3 meters from the fuel‐
ing spot, outdoors only.
Place the power tool on level ground, make sure
you have secure footing.
Engage the drill brake before starting. Otherwise,
the drilling tool may begin to run, causing the
user to lose control of the earth auger.
The machine is operated by a single person only
– do not allow any person to stay within the work‐
ing area – nor with starting.
To reduce the risk of injury, avoid contact with
the drilling tool.
Do not drop-start the engine – start it as descri‐
bed in the instructions for use.
Check idle speed setting: The drilling tool must
not rotate when the engine is idling with the throt‐
tle 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!
