Assembling guide bar and chain
A. Undo the guide bar nuts and remove
the clutch cover and
transport
packing
piece.
B. Place the guide bar into its rearmost
position.
Make sure that
the chain tensioning
stud is properly
in the hole in the guide
bar

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.
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.

E. Tension the chain while holding
up the bar tip. Do not tension
the chain stronger
than it can be pulled around
by hand.
Tighten
the guide bar nuts.
NOTE!
Do not forget to "run in" the chain and guide bar. Please see the
chain manufacturer's
recommendation.
CHECK THE CHAIN TENSION
FREQUENTLY
FOR OPTIMAL
PERFORMANCE
AND DURABIITY.
Fuel and oil
Fig, 4
The power plant of this chain saw is a
twostroke
engine, that is run on a petrol-
and oil mixture
of certain
proportions
ace. 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 O°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.
I
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.
Oil mixture:
Husqvarna
Twostroke
Oil 1:50
(270).
Ordinary
twostroke
oil 1:25
(47.)
Pre-mixed
oil 1:20
