MAINTENANCE
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 the air filter and the
area around the
carburettor. Replace the
air filter if necessary.
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 and lubricate
the bar sprocket tip.
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.
Cooling system
To obtain optimal 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.
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.
