Two-stroke oil
• For the best results use JONSERED two-stroke oil,
which is especially developed for chain saws. Mixing
ratio 1:50 (2%).
• If JONSERED two-stroke oil is not available, you
may use another two-stroke oil of good quality that
is intended for air cooled engines. Contact your
dealer when selecting an oil. Mixing ratio 1:33 (3%)-
1:25 (4%).
• Never use two-stroke oil intended for water cooled
outboard motors, so-called, outboard oil.
• Never use oil intended for four-stroke engines.
Mixing
• Always mix the petrol and oil in a clean container
intended for fuel.
• Always start by filling half the amount of the petrol to
be used. Then add the entire amount of oil. Mix
(shake) the fuel mixture. Add the remaining amount
of petrol.
• Mix (shake) the fuel mixture thoroughly before filling
the saw’s fuel tank.
• Do not mix more than max. one month’s supply of
fuel.
• If the saw is not used for some time the fuel tank
should be emptied and cleaned.
Fuelling
1. Clean around the fuel cap.
2. Open the fuel cap slowly so that any excess
pressure is released.
3. Tighten the fuel cap carefully after fuelling.
Clean the fuel tank regularly. The fuel filter should be
changed at least once a year. Contamination in the
fuel tanks causes malfunction. Make sure the fuel is
well mixed by shaking the container before fuelling.
