MAINTENANCE
36 – English
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).
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.
Note! The cooling system on a chain saw with catalytic
converter must be cleaned daily. This is particularly
important on chain saws with catalytic converters,
because the higher exhaust temperature requires
efficient cooling of the engine and the catalytic converter
unit.
”Dust Free” 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.
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.
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:
•
Preheat the intake air to the carburetor by using the
heat from the cylinder.
•
Partly mask the air inlet on the starter to increase the
working temperature of the engine.
Fitting the winterising kit (Optional
equipment)
Cut out a hole using a knife as shown.
Fit the winter cover (part no. 537 21 05-01) in the cylinder
cover.
Temperature 0
°
C (32
°
F) or colder:
Move the cover from position A to position B so that
preheated air from the cylinder can pass into the
carburettor compartment and prevent, e.g. the air filter
icing up again. When fitting the winter cover in position B
the centrifugal cleaning nozzle is blocked. This measure
requires the air filter to be cleaned more regularly.
Any maintenance other than that described in this
manual must be carried out by your servicing dealer
(retailer).
