pulled along the bar by hand. Retension if neces‐
sary – see "Tensioning the Saw Chain".
17.2.3 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 "Ten‐
sioning the Saw Chain".
NOTICE
The chain contracts as it cools down. If it is not
slackened off, it can damage the crankshaft and
bearings.
17.2.4 After a long period of full-throttle oper‐
ation
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 com‐
ponents (ignition, carburetor) from thermal over‐
load.
17.3 After finishing work
► 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.
17.3.1 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.
17.3.2 Long-term storage
See "Storing the machine"
18 Oil Quantity Control
Adjustable flow oil pump is a special option.
Different quantities of oil are required for different
bar lengths, types of wood and cutting techni‐
ques.

Use the adjusting screw (1) (on underside of
machine) to vary the oil feed rate as required.
Ematic position (E), medium oil flow rate –
► turn the adjusting screw to "E" (Ematic posi‐
tion).
To increase oil feed –
► turn the adjusting screw clockwise.
Turn reduce oil feed –
► turn the adjusting screw counterclockwise.
NOTICE
The chain must always be wetted with a film of

► Turn the guide bar over – every time you
sharpen the chain and every time you replace
the chain – this helps avoid one-sided wear,
especially at the nose and underside of the
bar.
► Regularly clean the oil inlet hole (1), the oil‐
way (2) and the bar groove (3)
► Measure the groove depth – with the scale on
the filing gauge (special accessory) – in the
area used most for cutting
