Fuei and oii
The power plant of this chain saw is a
twostroke engine, that is run on a petrol-
and oil mixture of certain proportions
acc. to the table.
Do not use but a twostroke oil of high
quality, e.g. Husqvarna Twostroke Oil, that
is specially developed for chain saws.
NOTE!
No extra oil is needed in the petrol during
the running-in period of the chain saw.
' For lubricating the chain and guide bar
. we recommend a chain lubricating oil
with good adhesive properties.
During the wintertime at air temperatures
below 0°C (32°F) some types pf chain
lubricating oils are viscous. This can
cause overloading of the oil pump,
which can result in damage of the pump
drive and pump parts. Under cold
weather conditions it is therefore ne­
cessary to use a “wintergrade” oil which
stays fluent even when cold'.
Concerning the choice of oil and its suit­
ability at different air temperatures,
please refer to your Husqvarna dealer.
Always use quality chain oil. If not available use gear box oil type
EP 90.
C. Fit the chain around the drive sprocket and in the groove of the
bar. Start on the upper side of the guide bar.
Make sure that the cutting edges of the sawing teeth along the
top of the guide bar are facing towards the tip. Also check that
the drive links go down properly into the drive sprocket.
D. Tension the chain so it does not sag along the bottom of the
guide bar. Check that the chain and guide bar fit properly.
Fit the clutch cover and tighten the nut fingertight only.
Pull the chain a few turns around by hand and check that it
can move freely.
ALWAYS TOP UP WITH FUEL AND CHAIN LUBRICANT AT
THE SAME TIME.
NOTE!
On no account waste oil should be used as this can damage the
oil pump.
