■ When sawing a branch that is under tension, expect it to
spring back. Once the tension in the wooden fibres is re-
leased, the branch can hit the operator and/or knock the
chainsaw out of his hands.
■ Be extremely careful when cutting brushwood and young
trees. The thin material can catch in the saw and fly in your
direction or knock you off balance.
Vibrations
m WARNING!
You can reduce the vibration risk, e.g. the risk of Raynaud's
phenomenon (circulatory problems), by taking regular breaks
during which you rub your hands together.
■ Always wear protective gloves and ensure your hands are
warm.
■ Make sure that the chain is always sharp.
■ Take regular work breaks.
Precautions against kickback
m WARNING!
Be aware of the danger of kickback when working with the
appliance. There is a risk of personal injury. You can avoid kick-
backs by being careful and using the correct sawing technique.
■ Contact with the tip of the rail can, in some cases, lead to
an unexpected rearwards reaction resulting in the guide rail
flying upwards towards the operator (fig. M).
■ Kickbacks can occur if the tip of the guide rail touches an
object or if the wood bends and the saw chain gets caught
in the cut.
■ If the saw chain jams in the upper edge of the guide rail, the
rail can kick back violently towards the operator (see fig. G).
■ If the saw chain jams in the lower edge of the guide rail, the
rail can jerk violently away from the operator (see fig. I).
■ Be extremely careful when reapplying the chain of the chain-
saw to a cut you have already begun.
■ Do not saw any branches or pieces of wood that can move
their position during sawing or in which the cut could close
during sawing.
■ Any such reaction can lead to you losing control over the saw
and possibly injuring yourself. Do not rely solely on the chain-
saw's built-in safety devices. As the user of a chainsaw, you
can take a number of measures to avoid accidents and injury.
A kickback is caused by incorrect use or misuse. It can be
avoided by taking proper precautions as given below.
■ Hold the saw firmly with both hands, with your thumb and
fingers around the handles of the chainsaw. Hold your body
and arms in a position in which you can withstand kickback
forces. If suitable measures are taken, the operator can control
the recoil forces. Never let go of the chainsaw (see fig. E).
■ Avoid an abnormal posture and do not saw over shoulder
height. This will prevent inadvertent contact with the tip of
the rail and allows a better control of the chainsaw in unex-
pected situations.
■ Always use the replacement rails and saw chains specified by
the manufacturer. Incorrect replacement rails and saw chains
can lead to a tearing of the saw chain and/or kickback.
■ Follow the manufacturer's instructions for sharpening and
maintenance of the saw chain. Setting the depth limiter too
low can increase the risk of kickback.
■ Do not saw with the tip of the blade. This can lead to a
kickback.
■ Make sure that there are no nails or pieces of metal in the
cutting area. Pay particular attention to nails and pieces
of iron in the area of the cut. Also be careful when cutting
hardwoods in which the chain could jam. This can lead to
a kickback.
■ Start the cut using full power and keep the chainsaw at top
speed while sawing.
■ Ensure that there are no objects on the ground that you can
trip over.
