Fuelmix

Gasoline

This engine is certified to

operate on unleaded
gasoline.

• Use good quality unleaded

gasoline.

• The lowest recommended

octane rating is 87. If you
run the engine on lower
octane rating than 87 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, which is

especially developed for chain saws. Mixing ratio 1:50 (2%).

• Never use two-stroke oil intended for water cooled outboard

engines, so-called, outboard oil.

• Never use oil intended for four-stroke engines.

FUEL HANDLING

Chain oil

• The chain lubrication

system is automatic. Always
use special chain oil with
good adhesive
characteristics.

• In countries where no

special chain oil is available,
EP 90 transmission oil can
be used.

• Never use waste oil. This

results in damage to the oil
pump, the bar and the
chain.

• It is important to use oil of

the right viscosity according
to the air temperature.

• In temperatures below 0

o

C

(32

o

F) some oils become

too viscous. This can
overload the oil pump and
result in damage to the oil
pump components.

• Contact your servicing

dealer when choosing chain
oil.

Always provide for good ventilation when
handling fuel.

!

IMPORTANT! The chain saw is equipped with a two-stroke
engine and must always been run using a mixture of gasoline
and two-stroke engine oil. It is important to accurately measure
the amount of oil to be mixed to ensure that the correct mixture
is obtained. When mixing small amounts of fuel, even small
inaccuracies can drastically affect the ratio of the mixture.

Mixing

• Always mix the gasoline

and oil in a clean container
intended for fuel.

• Always start by filling half

the amount of the gasoline
to be used. Then add the
entire amount of oil. Mix
(shake) the fuel mixture.
Add the remaining amount
of gasoline.

• 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.

• This engine is certified to

operate on unleaded
gasoline.
