■ Always hold the chainsaw with both hands when
operating the saw. Use a firm grip with thumbs and
fingers encircling the chainsaw handles. Right hand
must be on the rear handle and left hand on the front
handle.
■ Before starting the tool, make sure the saw chain is not
contacting any object.
■ Do not modify your tool in any way or use it to power
any attachments or devices not recommended by the
manufacturer for your saw.
■ There should be a first-aid kit containing large
wound dressings and a means to summon attention
(e.g., whistle) close to the operator. A larger more
comprehensive kit should be reasonably nearby.
■ The operator may be tempted to remove the helmet if
there is no danger of falling objects in the work area, but
remember the helmet, particularly with the mesh visor,
can help reduce the potential for injury to the face and
head if kickback occurs.
■ An incorrectly tensioned chain can jump off the guide
bar and could result in serious injury or fatality. The
length of chain depends on the temperature of the
chain and chain wear. Check the tension frequently.
■ You should get used to your new chainsaw by making
simple cuts on securely supported wood. Do this
whenever you have not operated the saw for some
time.
■ To reduce the risk of injury associated with contacting
moving parts, always stop the motor, apply chain brake,
remove the battery pack and make sure all moving
parts have come to a stop before:
cleaning or clearing a blockage
–
leaving the product unattended
–
installing or removing attachments
–
checking, maintenance or working on the machine
–
■ The size of the work area depends on the job being
performed as well as the size of the tree or work piece
involved. For example, felling a tree requires a larger
work area than making other cuts, i.e., bucking cuts,
etc. The operator needs to be aware and in control of
everything happening in this work area.
■ Do not cut with your body in line with the guide bar
and chain. If you do experience kickback this will help
prevent the chain coming into contact with your head
or body.
■ Do not use a back and forward sawing motion, let the
chain do the work, keep the chain sharp and don't try to
push the chain through the cut.
■ Do not put pressure on the saw at the end of the cut.
Be ready to take on the weight of the saw as it cuts free
from the wood. Failure to do so could result in possible
serious personal injury.
■ Do not stop the saw in the middle of a cutting operation.
Keep the saw running until it is already removed from
the cut.

PUSH AND PULL
See Fig. 3.
The reaction force is always opposite to the direction the
chain is moving. Thus, the operator must be ready to
control the tendency for the product to pull away (forward
motion) when cutting on the bottom edge of the bar and the
push backwards (towards the operator) when cutting along
the top edge.
SAW JAMMED IN THE CUT
Stop the chainsaw and make it safe. Do not try to force the
chain and bar out of the cut as this is likely to break the
chain which may swing back and strike the operator. This
situation normally occurs because the wood is incorrectly
supported and forcing the cut to close under compression
thereby pinching the blade. If adjusting the support does
not release the bar and chain, use wooden wedges or a
lever to open the cut and release the saw. Never try to start
the chainsaw when the guide bar is already in a cut or kerf.
