Oil Quantity Control - Stihl MS 261 Manual De Instrucciones

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".
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
Slacken off the chain if you have
N
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

Adjustable flow oil pump is a special
option.
Different quantities of oil are required for
different bar lengths, types of wood and
cutting techniques.

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"
N
(Ematic position).
To increase oil feed –
turn the adjusting screw clockwise.
N
Turn reduce oil feed –
turn the adjusting screw
N
counterclockwise.
The chain must always be wetted
with a film of lubricant.
