Air Filter Cleaning
DO NOT clean the air filter in
gasoline or other flammable
solutions. Doing so can create a fire
hazard or harmful emissions.
DO NOT operate the saw without an
air filter. Dust and dirt will be drawn
directly into the engine and damage
it. Keep the air filter clean.
1) Remove the top cover by
unscrewing the fastening screw.
2) Lift out the air filter.
3) Clean the air filter in warm, soapy
water and rinse in clean water.
4) Allow the filter to air dry
completely.
5) Insert the air filter back into the
chainsaw. Replace the cover on the
chainsaw. Make sure the cover is
fitted securely and properly before
tightening the screw.
Fuel Filter Cleaning
NEVER use the saw without a fuel
filter. After 100 hours of use, the filter
should be cleaned or replaced, if
damaged.
Make sure the fuel tank is empty
before changing the filter.
1) Remove the fuel tank cap.
2) Bend a piece of soft wire.
3) Reach into the tank opening and
hook the fuel line. Carefully pull the
line towards the opening until you
can reach it with your fingers.
DO NOT pull the hose completely
out of the tank.
4) Lift the filter out of the tank.
5) Pull off the filter. If it is damaged,
discard and replace with a new one.
6) Insert a new filter. Place the filter
into the opening and push it into the
tank. Make sure it is situated in the
lower corner of the tank. If need be,
use a long screwdriver to
move the filter into the correct
position. Be careful not to damage the
filter.
7) Fill the tank with new fuel mixture.
Spark Plug
The spark plug must be cleaned or
replaced after every 20 hours of
service.
1) Make sure the ON/OFF switch is
turned off.
2) Remove the top cover by
unscrewing the fastener.
3) Remove the air filter.
4) Disconnect the ignition cable from
the spark plug by pulling and twisting
simultaneously.
5) Remove the spark plug by using a
spark plug wrench.
6) Clean the spark plug with a copper
wire brush. The electrode gap should
be 0.6mm.
7) Reconnect the ignition cable.
8) Replace the air filter.
9) Replace the top cover, make sure
the cover is securely fitted, and then
screw down the fastener.
Carburetor
The carburetor has already been
properly adjusted at the factory. If it
requires additional adjustment, take
the saw to an authorized service
dealer.
Chain Bar Maintenance
The chain bar needs to be regularly
lubricated and maintained in order for
it to work.
Tools for lubrication
A lube gun is recommended, but not
required, for applying grease to the
guide bar sprocket tip. The gun is
equipped with a needle nose tip,
which allows the grease to be
efficiently applied.
Lubricating the sprocket tip
The sprocket tip on your new saw
has been pre-lubricated in the
factory. It needs to be lubricated
properly otherwise it will perform
poorly, and possibly seize.
Lubrication is recommended once a
week or after 10 hours of use. Clean
the bar tip before lubrication.
The chain does not have to be
removed to lubricate the bar tip.
Lubrication is possible while
working, however the engine must
be turned off.
Warning: Wear work gloves when
handling the chain and bar.
1) Make sure the engine is off, with
the ON/OFF switch in the Off
position.
2) Clean the guide bar tip.
3) Using the lubrication gun, insert
the nose into the lubrication hole and
fill it with grease until it appears at
the edges of the tip.
4) Rotate the saw by hand. Add
additional lubrication until the entire
tip has been greased.
Many guide bar problems can be
avoided by properly maintaining the
bar and chain saw. Insufficient
lubrication or using a saw with a
chain that is too tight will cause the
bar to wear rapidly.
Maintaining the chain bar
The bar should be reversed after 8
hours of work to keep uniform wear.
Check the bar frequently for wear,
and if need be, remove burs and
square up the rails by using the flat
file.
1) Be sure the ON/OFF switch is Off.
2) Loosen the bar knob and remove
the cover.
3) Remove the chain and bar from
the saw.
