During operation
N Check level in chain oil tank.
N Top up with chain oil when the "min"
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".
NOTICE
The chain contracts as it cools down. If it
is not slackened off, it can damage the
drive shaft and bearings.
After finishing work
N Disconnect the plug from the wall
outlet.
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 drive shaft and
bearings.
Storing for a long period
See chapter on "Storing the Machine"
N Flip the bar – after each sharpening
and each time the chain is changed
– to avoid uneven wear, especially
at the sprocket nose and on the
bottom
N Periodically clean the oil inlet
hole (1), oil outlet channel (2) and
bar groove (3)
N Measure groove depth – using the
measuring tool on the file gauge
(special accessory) – in the area
with the greatest wear
