Lubricating The Bar Tip Sprocket; Needle Bearing Lubrication; Cooling System; Air Injection" Centrifugal Cleaning - Husqvarna 440 e-series Owner's Manual

Lubricating the bar tip sprocket

Lubricate the bar tip sprocket each time you refuel. Use
the special grease gun and a good quality bearing grease.
(109)

Needle bearing lubrication

The clutch drum has a needle bearing on the output shaft.
This needle bearing must be lubricated regularly.
When lubricating, remove the clutch cover by loosening
the two bar nuts. Lay the saw on its side with the clutch
drum upwards.
Lubrication involves engine oil dripping into the centre of
the clutch drum as it rotates. (110)

Cooling system

To keep the working temperature as low as possible the
machine is equipped with a cooling system.
The cooling system consists of:
1 Air intake on the starter.
2 Air guide plate.
3 Fins on the flywheel.
4 Cooling fins on the cylinder.
5 Cylinder cover (directs cold air over the cylinder).
(111)
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.
"Air Injection" centrifugal
cleaning
Centrifugal cleaning means the following: All air to the
carburetor passes through the starter. Dirt and dust is
pushed out by the cooling fan. (112)
IMPORTANT! In order to maintain operation of the
centrifugal cleaning system it must be regularly
maintained. Clean the air intake to the starter, the fins on
the flywheel, the space around the flywheel, inlet pipe and
carburetor compartment.

MAINTENANCE

Winter use

Running problems can occur when using the machine in
the cold and snowy conditions caused by:
• Too low engine temperature.
• Icing of the air filter and carburetor.
Special measures are therefore often required:
• Partly mask the air inlet on the starter to increase the
working temperature of the engine.
Temperature -5° ° ° ° C (23° ° ° ° F) or colder:
For running the machine in cold weather or powder snow,
a special cover is available, which is mounted on the
starter housing. This reduces the intake of cold air and
prevents large amounts of snow from being sucked in.
(113)
NB! If the special winterising kit has been fitted or any
measures have been taken to increase the temperature
these changes must be reversed before the machine is
used in normal temperature conditions. Otherwise there
is a risk of overheating, resulting in severe damage to the
engine.
IMPORTANT! Any maintenance other than that described
in this manual must be carried out by your servicing
dealer (retailer).
