Husqvarna 55 Rancher Chainsaw Owners Manual

MAINTENANCE
Needle bearing lubrication
”Air Injection” centrifugal cleaning
Centrifugal cleaning means the following: All air to the
carburettor passes through the starter. Dirt and dust is
centrifuged out by the cooling fan.
The clutch drum is tted with one of the following drive
sprockets:
A   Spur sprocket (the chain sprocket is welded on the
drum)
B   Rim sprocket (replaceable)
IMPORTANT! In order to maintain operation of the centrifugal
cleaning system it must be regularly maintained.
Clean the air intake to the starter, the ns on the ywheel,
the space around the ywheel, inlet pipe and carburettor
compartment.
Both versions have a needle bearing on the drive shaft, which
has to be greased regularly (once a week).
CAUTION! Use only high quality bearing grease or engine oil.
Winter use
Cooling system
During cold weather and under powder snow conditions,
operating problems can arise due to:
Too low engine temperature.
Icing of the air lter and carburettor.
To keep the working temperature as low as possible the
machine is equipped with a cooling system.
Special measures are therefore often required:
Partly mask the air inlet on the starter to increase the
working temperature of the engine.
The cooling system consists of:

Air intake on the starter.
Air guide plate.
Preheat the intake air to the carburettor by removing the
seal between the cylinder and the carburettor space.
Fins on the ywheel.
Cooling ns on the cylinder.
Temperature 0°C (32°F) or colder:
Cylinder cover (directs cold air over the cylinder).

Twist the cover so that preheated air from the cylinder can
enter the carburettor space to prevent icing of the air lter,
etc., then t the rubber seal to the fuel pipe by the main air
intake.

Clean the cooling system with a brush once a week, more
often in demanding conditions. A dirty or blocked cooling
system results in the machine overheating which causes
damage to the piston and cylinder.
