After the blades have been sharpened 3-4 times,
check the height of the depth limiter and if necessary
lower it with a flat file and then round off the front
corner (Fig. 24).
Chain tension
Check the chain tension frequently and adjust as
often as necessary to keep the chain snug on the bar,
but loose enough to be pulled around by hand. (see
also point 5.3)
Breaking in a new saw chain
A new chain and bar will need chain readjustment
after as few as 5 cuts. This is normal during the break-
in period, and the interval between future adjustments
will begin to lengthen quickly.
Notice:
Never have more than 3 links removed from a
loop of chain. This could cause damage to the
sprocket.
Chain lubrication
Always make sure the automatic oiler system is
working properly. Keep the oil tank filled with Chain,
Bar and Sprocket Oil.
Adequate lubrication of the bar and chain during
cutting operations is essential to minimize friction with
the guide bar.
Never starve the bar and chain of lubricating oil.
Running the saw dry or with too little oil will decrease
cutting efficiency, shorten saw chain life, cause
rapid dulling of chain, and lead to excessive wear of
bar from overheating. Too little oil is evidenced by
smoke or bar discoloration.
7.3 Storage
Notice:
Never put a chain saw into storage for longer
than 30 days without carrying out the following steps.
Storing a chain saw
Storing a chain saw for longer than 30 days requires
storage maintenance. Unless the storage instructions
are followed, fuel remaining in the carburetor will
evaporate, leaving gum-like deposits. This could lead
to difficult starting and result in costly repairs.
1.
Remove the fuel tank cap slowly to release any
pressure in tank. Carefully drain the fuel tank.
2.
Start the engine and let it run until the unit stops
to remove fuel from carburetor.
3.
Allow the engine to cool (approx. 5 minutes).
4.
Remove the spark plug (7.2.4).
5.
Pour 1 teaspoon of clean 2-cycle oil into the
combustion chamber. Pull starter rope slowly
several times to coat internal components.
Replace spark plug (Fig. 25).
Notice:
Store the unit in a dry place and away from
possible sources of ignition such as a furnace, gas
hot water heater, gas dryer, etc.
Puttig the saw back into operation
1.
Remove spark plug (see also point 7.2.4).
2.
Pull starter rope briskly to clear excess oil from
combustion chamber.
3.
Clean the spark plug and check that the electrode
gap is correct.
4.
Prepare unit for operation.
5.
Fill fuel tank with proper fuel / oil mixture. See
Fuel and Lubrication Section.
