Chain cold
Tension is correct when the chain fits
snugly against the underside of the bar
but can still be pulled along the bar by
hand. Retension if necessary – see
"Tensioning the Saw Chain".
Chain at operating temperature
The chain stretches and begins to sag.
The drive links must not come out of the
bar groove on the underside of the bar –
the chain may otherwise jump off the
bar. Retension the chain – see
"Tensioning the Saw Chain".
NOTICE
The chain contracts as it cools down. If it
is not slackened off, it can damage the
crankshaft and bearings.
After a long period of full-throttle
operation
After a long period of full-throttle
operation, allow engine to run for a while
at idle speed so that the heat in the
engine can be dissipated by flow of
cooling air. This protects engine-
mounted components (ignition,
carburetor) from thermal overload.
After finishing work
N
Slacken off the chain if you have
retensioned it at operating
temperature during work.
NOTICE
Always slacken off the chain again after
finishing work. The chain contracts as it
cools down. If it is not slackened off, it
can damage the crankshaft and
bearings.
Short-term storage
Wait for engine to cool down. Keep the
machine with a full tank of fuel in a dry
place, well away from sources of
ignition, until you need it again.
Long-term storage
See "Storing the machine"
Varying cutting lengths, types of wood
and working techniques require varying
quantities of oil.
Standard oil pump
The oil delivery rate can be adjusted as
needed using the adjusting screw (1)
(on the bottom of the machine).
Ematic setting (E), moderate oil delivery
rate –
N
Turn adjusting screw to "E" (Ematic
setting)
Increase oil delivery rate –
N
Turn the adjusting screw clockwise
Reduce oil delivery rate –
N
Turn the adjusting screw
counterclockwise
NOTICE
The saw chain must always be coated
with chain oil.
