CLEANING THE SPARK ARRESTING SI-
LENCER
The silencer is equipped with a spark arrester screen.
A faulty spark arrester screen can create a fire hazard.
Through normal use the screen becomes dirty and should
be inspected weekly and cleaned as required. Always keep
the silencer and spark arrester on your saw in good condition.
WARNING
Silencer surfaces are very hot during and after
operation of the chainsaw: keep all body parts away
from the silencer. Serious burns may occur if contact is
made with the silencer.
1.
Allow the silencer to cool.
2.
The spark arrester screen is retained by the deflector.
Remove the three nuts and screen retainer to access
the spark arrester screen.
3.
Replace the spark arrester screen if it is cracked or
otherwise deteriorated.
CHAIN BRAKE
Remove the clutch cover and clean the chain brake
components. Check wear on the brake band and replace
if worn or deformed. The band thickness should not be
less than 0.60 mm (0.024 in.), or worn halfway through.
Always keep the chain brake mechanism clean and
lightly lubricate the linkage.
Always test the chain brake performance after servicing
or cleaning. Refer to “Operation - Operating Chain Brake”
earlier in this manual for additional information.
Check and, if damaged, replace the chain catcher.
STORING THE CHAINSAW (1 MONTH
OR LONGER)
1.
Drain all fuel from tank into a container approved for petrol.
2.
Run the engine until it stops. This will remove all fuel-oil
mix which could become stale and leave varnish and gum
in the fuel system.
3.
Drain all bar and chain oil from tank into a container
approved for oil.
4.
Clean all foreign material from the saw.
5.
Store it in a well ventilated place that is inaccessible
to children.
NOTE:
Keep away from corrosive agents such as garden
chemicals and de-icing salts.
Abide by all regulations for the safe storage and handling of
petrol. Excess fuel should be used in other 2-cycle engine
powered equipment.
