Operating Instructions

During Operation
Check level in chain oil tank.
N
Top up with chain oil when the "min"
N
mark is reached, or earlier – see
"Filling the Chain Oil Tank".
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".
The chain contracts as it cools down. If it
is not slackened off, it can damage the
drive shaft and bearings.

After Finishing Work
Disconnect the plug from the wall
N
outlet.
Slacken off the chain if you have
N
retensioned it at operating
temperature during cutting work.
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 drive shaft and
bearings.
Storing for a long period

Taking Care of the Guide Bar

2
1
Turn the bar over – every time you
N
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),
N
the oilway (2) and the bar
groove (3).
Measure the groove depth – with the
N
scale on the filing gauge (special
accessory) – in the area used most
for cutting.
