General Safety Precautions - Jonsered CS2156 Operator's Manual

4 Never use the chain saw above shoulder height and try
not to cut with the tip of the bar. Never use the chain saw
one-handed!
5 You must have a steady stance in order to have full control
over the chain saw. Never work standing on a ladder, in a
tree or where you do not have firm ground to stand on.
6 Always use a fast cutting speed, i.e. full throttle.
7 Take great care when you cut with the top edge of the bar,
i.e. when cutting from the underside of the object. This is
known as cutting on the push stroke. The chain tries to
push the chain saw back towards the user.

Unless the user resists this pushing force there is a risk
that the chain saw will move so far backwards that only the
kickback zone of the bar is in contact with the tree, which
will lead to a kickback.
Cutting with the bottom edge of the bar, i.e. from the top
of the object downwards, is known as cutting on the pull
stroke. In this case the chain saw pulls itself towards the
tree and the front edge of the chain saw body rests

SAFETY INSTRUCTIONS
naturally on the trunk when cutting. Cutting on the pull
stroke gives the operator better control over the chain saw
and the position of the kickback zone.
9 Follow the instructions on sharpening and maintaining
your bar and chain. When you replace the bar and chain
use only combinations that are recommended by us. See
instructions under the headings Cutting equipment and
Technical data.
WARNING! The risk of kickback is increased
!
if you use the wrong cutting equipment or a
chain that is not sharpened correctly. The
wrong combination of bar and chain can
increase the risk of kickback!
