During Operation
Check chain tension frequently
A new chain has to be retensioned more
often than one that has been in use for
some time.
Chain cold
Tension is correct when the chain fits
snugly against the underside of the bar
and 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 – 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
gear shaft and bearings.
After Finishing Work
N Slacken off the chain if you have
retensioned it at operating
temperature during cutting work.
NOTICE
Always slacken off the chain after
finishing work. The chain contracts as it
cools down. If it is not slackened off, it
can damage the gear shaft and
bearings.
Storing for a long period
See chapter on "Storing the Machine"
For periods of 3 months or longer
N Remove the saw chain and guide
bar, clean them and spray with
corrosion inhibiting oil.
N If you use a biological chain and bar
lubricant, e.g. STIHL BioPlus,
completely fill the chain oil tank.
N If the KombiTool is removed from
the KombiEngine and stored
separately: Fit the protective cap on
the drive tube to avoid dirt getting
into the coupling.
N Store the machine in a dry, high or
locked location – out of the reach of
children and other unauthorized
persons.
