English
the chain may otherwise jump off the
bar. Retension the chain – see
"Tensioning the Saw Chain".
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.
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"

Oil Quantity Control
Varying cutting lengths, types of wood
and working techniques require varying
quantities of oil.
Standard oil pump
1
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
The saw chain must always be
coated with chain oil.
Oil pump with increased delivery rate
(available option)
The oil pump with increased delivery
rate can be identified by the groove (2)
in the adjusting screw.
With this oil pump, in setting range a, the
oil tank can run empty before the fuel
tank, thus causing the saw chain to run
dry.
N in setting range a, fill the fuel tank
only half full or refill the oil tank
when the fuel tank is approximately
half empty
