12 – English
Petrol
• Use unleaded or quality
leaded petrol.
• The lowest recommended
octane rating is 90. If you
run the engine on a petrol
with a lower octane rating
than 90 so-called
"knocking" can occur.
This leads to an increased
engine temperature,
which can result in a
serious engine breakdown.
• When working at
continuous high revs a
higher octane rating is
recommended.
Two-stroke oil
• For the best results use Jonsered two-stroke oil. Mixing
ratio 1:50 (2%).
• If Jonsered two-stroke oil is not available you can se a high
quality two-stroke oil intended for air cooled engines.
Contact your dealer when selecting an oil.
Mixing ratio: 1:33 (3%).
• Never use two-stroke oil intended for water cooled
outboard motors, so-called outboard motor oil.
• Never use oil intended for four-stroke engines.
Mixture
• Always mix petrol and oil in a clean container intended for
petrol
• Always start by filling half the quantity of petrol required.
Then add the entire oil quantity. Mix (shake) the fuel
mixture. Fill the remaining quantity of petrol
• Mix (shake) the fuel mixture carefully before filling in the
machine's fuel tank.
• Do not mix fuel for more than approx. 2 months use.
• If the machine is not used for a long period of time, the
fuel tank should be emptied and cleaned.

Start and stop – Maintenance
Stopping
Air filter
The engine is stopped by
switching off the ignition.
Move the stop switch
backwards to the STOP
position.
The air filter must be
cleaned from dust and dirt
in order to avoid:
• Carburettor malfunctions.
• Starting problems.
• Engine power reduction.
• Unnecessary wear on the
engine parts.
• Abnormal fuel
consumption.
Cleaning/changing the air filter
Carburettor setting
In the carburettor, fuel is
mixed with air. When the
engine is test run at the
factory, the carburettor is
basically adjusted. A further
adjustment may be required,
according to climate and
altitude. The carburettor has
one adjustment possiblity:
T = Idle speed adjustment
screw ”IDLE”.
Clean the filter after every 25 hours or more regularly if
operating conditions are exceptionally dusty.
Dismantle the air filter cover and remove the air filter. Wash
in clean, warm soapy water.
Ensure that the filter is dry before refitting.
An air filter used for a long period of time can never be
cleaned completely. Therefore it is necessary to replace the
filter from time to time with a new filter. A damaged air filter
must always be replaced.
Spark plug
The condition of the spark
plug is affected by:
• An incorrect carburettor
setting.
• An incorrect fuel mixture
(too much oil).
• A dirty air filter.
These factors cause deposits
on the spark plug electrode
that may result in
malfunction or starting
difficulties.
0,5 mm
Adjustment (T) ”IDLE”
Check that the air filter is clean.
When the idle speed is correct, the cutter will not move.
If adjustment is required, close (clockwise) the T-screw, with
the engine running, until the cutter starts to move . Open
(counter-clockwise) the screw until the cutter stops. You have
reached the correct idle speed when the engine runs smoothly
in all positions well below the rpm when the cutter starts to
move.
If the cutter still moves after idle speed adjustment, contact
your service workshop.
If the machine is low on power, difficult to start or runs
poorly while idling always check the spark plug first.
If the spark plug is dirty, clean it and at the same time check
that the electrode gap is 0.5 mm. The spark plug should be
changed after about one month of operation or earlier if
necessary.
NOTE!
Always use the recommended type of spark plug. An incorrect
spark plug can damage the cylinder/piston.
WARNING!
When the engine is idling the cutter must
under no circumstances move.
