Checking chain lubrication
Breaking
in
the Oilomatic chain
Every new chain has to be broken
in
for about 2
to
3
minutes. Ample chain lubrication is essential during this
period. After breaking in, check chain tension and adjust
if
necessary.
Correct chain tension
The chain must always be slackened off after finishing
cutting work. A chain properly tensioned when
it
is warm
would, when the temperature drops, be subjected to such
great contraction stresses that the chain would break and
also damage the crankshaft and bearings.
The Oilomatic chain must, therefore, always be tensioned
(with the engine shut off) before you start cutting. Chain
tension is correct
in
the cold condition when the chain fits
snugly
on
the underside of the bar and can still be pulled
around the bar by hand - take care, the cutting edges are
very sharp.
Worn chain sprocket
When the chain saw is operated in extremely cold weather
a correctly cold-tensioned Oilomatic chain will begin to sag
noticeably as
it
warms
up
to normal operating temperature.
The chain must then be retensioned. However,
it
must
be
slackened off again immediately after you stop the saw.
This is necessary to avoid contraction stress which would
occur as the chain cools down
to
ambient temperature.
A new chain must be retensioned more frequently until it is
fully stretched.
Chain sprocket
The stress and strain
on
the chain sprocket are particularly
high.
If
the wear marks
on
the teeth are very pronounced
(about 0.5 mm/0.02 in), the sprocket should
be
replaced.
A worn sprocket reduces the service life of your saw chain.
Replace the chain sprocket with every second Oilomatic
chain. It is best to use two chains alternately with one
sprocket.
