Oil passages
Oil passages on the bar should be cleaned to en-
sure proper lubrication of the bar and chain during
operation.
Note: The condition of the oil passages can be
easily checked. If the passages are clear, the
chain will automatically give off a spray of oil
within seconds of starting the saw. Your saw is
equipped with an automatic oiler system.
Automatic chain lubrication.
The chain saw is equipped with an automatic oil
lubrication system with a toothed wheel drive. It
automatically supplies the bar and the chain with
the right quantity of oil. The moment the engine is
accelerated, the oil also starts to fl ow through the
bar plate more quickly as well.
The chain lubrication system has been set to its
perfect adjustment at the factory. If it requires
adjusting, take the saw to your nearest authorized
after-sales service outlet.
A setting screw for adjusting the chain lubrication
(Fig. 26/ Item A) is located on the underside of the
chain saw. Turning the screw counter-clockwise
increases the chain lubrication, turning it clockwi-
se decreases the chain lubrication.
To check the chain lubrication, hold the chain
saw, with the chain, over a piece of paper and run
it at full speed for a few seconds. You will be able
to judge the set amount of oil from the paper.
7.2.7 Chain maintenance
Chain sharpening
Chain sharpening requires special tools to ensure
that cutters are sharpened at the correct angle
and depth. For the inexperienced chain saw user,
we recommend that the saw chain be professio-
nally sharpened by the nearest professional Ser-
vice Center. If you feel comfortable sharpening
your own saw chain, special tools are available
from the professional Service Center.
Chain sharpening (Fig. 23)
Sharpen the chain using protective gloves and a
round fi le of ø3/16” (4.8mm).
Always sharpen the cutters only with outward
strokes (Fig. 23) observing the values given in
Fig. 22.
After sharpening, the cutting links must all have
the same width and length.
Note: A sharp chain produces well-defi ned chips.
When your chain starts to produce sawdust, it is
time to sharpen.
After the blades have been sharpened 3-4 times,
check the height of the depth limiter and if neces-
sary lower it with a fl at fi le 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.
Note: 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 fi lled 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 de-
crease cutting effi ciency, shorten saw chain life,
cause rapid dulling of chain, and lead to exces-
sive wear of bar from overheating. Too little oil is
evidenced by smoke or bar discoloration.
7.3 Storage
Note: Never put a chain saw into storage for
longer than 30 days without carrying out the fol-
lowing steps.
Storing a chain saw
Storing a chain saw for longer than 30 days re-
quires storage maintenance. Unless the storage
instructions are followed, fuel remaining in the
carburetor will evaporate, leaving gum-like depo-
sits. This could lead to diffi cult starting and result
in costly repairs.
1. Remove the fuel tank cap slowly to release
any pressure in tank. Carefully drain the fuel
tank.
