C Clearing the trunk and preparing your retreat
Remove any branches that
are in the way. To do this it is
best to work from the top
down and keep the trunk
between you and the chain
saw. Never limb above
shoulder height.
Remove any undergrowth
from the base of the tree and

We recommend that you use
a bar that is longer than the
diameter of the tree, so that
you can make the FELLING
CUT and DIRECTIONAL CUT
with single cutting stokes.
(See 
ÓTechnical dataÓ to find
out which lengths of bar are
recommended for your saw).
There are methods for felling
trees with a diameter larger
than the bar length. However
these methods involve a much
greater risk that the kickback
zone of the bar will come into
contact with the tree.

FUEL HANDLING
Chain oil
¥ The chain lubrication
system is automatic. Always
use special chain oil with
good adhesive
characteristics.
¥ In countries where no
special chain oil is available,
EP 90 transmission oil can
be used.
¥ Never use waste oil. This
results in damage to the oil
pump, the bar and the
chain.
¥ It is important to use oil of
the right viscosity according
to the air temperature.
¥ In temperatures below 0
oC
(32oF) some oils become
too viscous. This can
overload the oil pump...
