RECOMMENDED OIL GRADE
Use quality oil only, API classification TC (TSC-3) which
is offered for air-cooled two-stroke engines. Mix the oil
for two-stroke engines according to the instructions
on the container, 1:40 (2.5%).
RECOMMENDED PETROL GRADE
Always use clean, fresh lead-free petrol
(maximum 60 days old).
Minimum octane number: 91 ROZ
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 the
engine is quite different (and much easier) from what you
are used to.
1. Mix petrol (gasoline) with oil. Fill the tank with the mixture.
See instructions on mixing oil and petrol.
2. Put the ignition switch in the START (I) position (Fig. 17).
NOTE: On some models the switch is permanently in the
ON [I] position.
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.
3. Slowly and fully press the intake pump 10 times. The fuel
must be visible in the pump (Fig. 18). If this is not the
case, press a further three times or until the fuel can
be seen.
On appliances with a choke lever
4. Move the choke lever to position 1 (Fig. 18).
TIP: Note: Ensure that the choke has engaged
in position (1).
5. With the unit on the ground, press the throttle lock
and actuate the throttle. Hold down the throttle.
Pull the starter rope three times in a controlled and
continuous movement (Fig. 19).
6. Move the choke lever to position 2 (Fig. 18).
7. To start the engine, pull the starter rope in a controlled
and continuous movement 1–5 times (Fig. 19).
8. Press on the throttle to warm up the engine for 15–30
seconds.
NOTE: At lower temperatures the engine may require longer
to warm up and reach maximum speed.

OIL AND FUEL RECOMMENDATIONS
OPERATING MANUAL
INSTRUCTIONS FOR MIXING OIL AND PETROL
Age and/or incorrectly mixed fuel are the main reasons for
the unit not running properly. Use fresh, 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.
NOTE: The unit has warmed up adequately when the engine
accelerates without faltering.
9. When the engine has warmed up, move the choke lever
to position 3 (Fig. 18). The unit is now ready to use.
IF... the engine falters, move the choke lever to position 2
(Fig. 18) and leave the engine to warm up longer.
IF... the engine does not start, repeat steps 3–7.
IF... 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.
IF... Move the choke lever to position 3 if the engine
floods when attempting to start it. Press the throttle.
Pull forcefully on the starter rope. The engine must start
after 3 (three) to 8 (eight) attempts.
On appliances without a choke lever
1. Pull the starter rope in controlled and continuous
movement, unil the engine starts (Fig. 19).
NOTE: During the starting process do not actuate
the throttle.
2. After starting the engine, wait 10–15 seconds before
you actuate the throttle.
IF... the engine fails to start repeat the procedure.
SWITCHING OFF THE UNIT
1. Take your hand off the throttle (Fig. 17). Leave the
idling engine to cool down.
2. Move the switch (depending on model) to the OFF [0]
position and hold (depending on model) until the engine
is off (Fig. 17).
