Taking Care Of The Guide Bar - Stihl MS 210 Manual De Instrucciones

English
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
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.

N
Turn the 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.
N Regularly clean the oil inlet hole (1),
the oilway (2) and the bar
groove (3).
N Measure the groove depth – with
the scale on the filing gauge (special
accessory) – in the area used most
for cutting.
