Always use clean, fresh lead-free
petrol (maximum 60 days old).
Fill the tank with petrol.
Remove the tank cap.
n
Fill fuel tank. Never overfill!
n
Firmly close the petrol tank again.
n
Move the unit approx. 10 m
n
from the filling station/fuel
container before starting the
engine.
See instructions on mixing oil
and petrol
Age and/or incorrectly mixed fuel
are the main reasons for the unit
not running properly. Use fresh,
8
clean, lead-free petrol only.
Follow exactly the instructions for
the correct petrol/oil mixture.
Correctly mix two-stroke engine oil
and lead-free petrol, 1:40 (2.5 %).
Do not mix directly in the tank.

Operating manual

Starting the engine
Note:
The engine uses Advanced Starting
Technology™ (spring-supported
starting process) which significantly
reduces the energy expenditure
required to start the engine.
You must pull out the starter rope
until the engine starts by itself
(spring-supported). It is not
necessary to pull violently on the
rope – the pulled rope does not
resist greatly. Please note that this
method of starting theengine is quite
different (and much easier) from
what you are used to.
Mix petrol (gasoline) with oil.
n
Fill the tank with the mixture.
See instructions on mixing oil
and petrol.
Put the ignition switch in the
n
START [I] position (Fig. 9).
Tip:
If starting a unit which has not been
used for a long time (or brand new or
difficult to start), press the intake
pump 20 times.
Slowly and fully press the intake
n
pump (7) 10 times. The fuel must
be visible in the pump (Fig. 10). If
this is not the case, press a further
three times or until the fuel can be
seen.
On appliances with
a choke lever
Move the choke lever to position 1
n
(Fig. 10).
Place the unit on the ground,
n
actuate the choke and hold down
the lever. Pull the starter cord
three times in a controlled,
constant movement (Fig 11).
Operating instruction
Move the choke lever to position 2
n
(Fig. 10).
To start the engine, pull the starter
n
rope (8) in a controlled and
continuous movement 1–5
times (Fig. 11).
Press on the throttle to warm
n
up the engine for 15–30 seconds.
Note
At lower temperatures the engine
may require longer to warm up and
reach maximum speed.
The unit has warmed up adequately
when the engine accelerates without
faltering.
When the engine has warmed up,
n
move the choke lever to position 3
(Fig. 10). The unit is now ready
to use.
If the engine falters, move the
choke lever to position 2 (Fig. 10)
and leave the engine to warm
up longer.
If the engine does not start, repeat
steps 3–7.
Notes:
– It is not necessary to use the
choke to start a hot engine. Move
the switch to the On [I] position
and the choke lever to position 2.
– Move the choke lever to position
3 if the engine floods when
attempting to start it. Press the
throttle. Pull on the starter rope.
The engine must start after
3 (three) to 8 (eight) attempts.
On appliances without
a choke lever
Pull the starter rope in controlled
n
and continuous movement, until
the engine starts (Fig. 11).
NOTE: During the starting
process do not actuate the
throttle.
After starting the engine, wait
n
10–15 seconds before you
actuate the throttle.
Notes
If the engine fails to start repeat the
procedure.
