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.
Below you will find some general maintenance instructions.
If you have more questions, contact your servicing dealer.
Daily maintenance
1. Check the throttle trigger
for smooth operation. If
any binding occurs, or if
engine fails to return to
idle, the saw should be
taken to your dealer,
before it is used again.
Also, be sure that the
trigger cannot be pulled
until the throttle trigger
lockout is depressed.
2. Clean the chain brake
and check its function
according to the
instructions. Make sure
that the chain catcher is
undamaged. Otherwise
replace it immediately.
3. Clean or replace the air
filter as necessary. Check
for damage or holes.
4. The bar should be turned
daily for more even wear.
Check the lubrication hole
in the bar, to be sure it is
not clogged. Clean the
bar groove, if the bar has
a sprocket tip, this should
be lubricated.
5. Check the function of the
oiler to be sure the bar
and chain receive proper
lubrication.
6. Sharpen the chain and
check its tension and
condition. Check the drive
sprocket for wear.
Replace if necessary.
7. Check the starter and
starter cord for wear or
damage. Clean the air
intake slots on the starter
housing.
8. Check for any loose nuts
and screws and retighten
if necessary.
9. Test the stop switch to be
sure it shuts off the
engine.

Centrifugal cleaning ”Air Injection”
Centrifugal cleaning means
the following:
All air to the carburetor is
carried through the starter.
Dirt and dust is centrifuged
away by the cooling fan.
IMPORTANT! In order to
keep the function of the
centrifugal cleaning, a
continous maintenance and
care must be made.
• Clean the air intake to the
starter, the fan wings of the
flywheel, the space around
the flywheel, inlet pipe and
carburetor space.
