SAFETY INSTRUCTIONS
•
Take great care when removing small branches and avoid
cutting bushes (i.e. cutting many small branches at the
same time). Small branches can be grabbed by the chain
and thrown back at you, causing serious injury.

•
Make sure you can move and stand safely. Check the area
around you for possible obstacles (roots, rocks, branches,
ditches, etc.) in case you have to move suddenly. Take
great care when working on sloping ground.

•
Take the utmost care when cutting through branches or logs
that are in tension. A log or branch that is in tension can
suddenly spring back into its natural position before or after
you cut it. If you stand on the wrong side or start cutting in
the wrong place it may strike you or your chain saw, so that
you lose control. Both situations could cause serious injury.

•
Before moving your chain saw switch off the engine and
lock the chain using the chain brake. Carry the chain saw
with the bar and chain pointing backwards. Fit a guard to
the bar before transporting the chain saw or carrying it for
any distance.

Basic cutting technique
General
•
Always use full throttle when cutting!
•
Reduce the speed to idle after every cut (running the
engine for too long at full throttle without any load, i.e.
without any resistance from the chain during cutting, can
lead to serious engine damage).

lead to serious engine damage).
•
Cutting from above = Cutting on the pull stroke.
•
Cutting from below = Cutting on the push stroke.
Cutting on the push stroke increases the risk of kickback. See
instructions under the heading How to avoid kickback.

consider before making a cut:
1
Make sure the cutting equipment will not jam in the cut.
2
Make sure the object you are cutting will not split.
3
Make sure the chain will not strike the ground or any other
object during or after cutting.

4
Is there a risk of kickback?
5
Do the conditions and surrounding terrain affect how
safely you can stand and move about?
safely you can stand and move about?
Two factors decide whether the chain will jam or the object
that you are cutting will split: the first is how the object is
supported before and after cutting, and the second is whether
it is in tension.
