MAINTENANCE
Cooling system
To obtain the lowest possible running temperature the saw is
equipped with a cooling system.
The cooling system
consists of:
1. Air intake on the starter
unit.
2. Air guide plate.
3. Fan blades on the
flywheel.
4. Cooling fins on the
cylinder.
5. Cylinder cowling
(supplies cold air over
the cylinder).
Clean the cooling system with a brush once a week, more often
in demanding conditions. A dirty or blocked cooling system
results in the saw overheating which causes damage to
piston and cylinder.
!
WARNING! The engine must not be running
when making adjustments.
Extra chain oil
The chain - bar can, under
EXTREME conditions, require
an increased amount of chain
oil. The extra flow should only
be engaged when the engine
is running and the chain
rotating. Push the lever to the
right, where it automatically
remains in the blocked
position. Press in the lever’s
button to reset.
Note: it is not necessary to
pump continuously.
When the extra oil flow has
been activated oil
consumption increases by 40-
80%, depending on the oil
pump’s basic setting.
Recommended settings:
Bar 24"-28": 0 turns from the closed position.
Bar 28"-34": 3/4 turns from the closed position.
Bar 34"-42": 1 1/2 turns from the closed position.
Bar 42" and longer: 1 3/4 turns from the closed position.
These recommendations apply to Husqvarna’s chain oil, for
other chain oil increase the oil flow by one step.
Adjustment of the oil pump
The oil pump is adjustable.
Adjustments are made by
turning the screw using a
screwdriver or combination
spanner.
The saw is supplied from the
factory set to 1 turn open.
Turning the screw clockwise
will reduce the oil flow and
turning the screw anti-
clockwise will increase the oil
flow.
