Always hold the power saw with your right hand by the rear grip and with your left hand by the front grip. Holding the
power saw the other way round should never happen, as it increases the risk of injury.
Hold the power saw by the insulated grips only, as the chain may come into contact with a concealed wire or the chainsaw’s
power cord. The chain contacting a “live” wire may make metal parts become “live” and could give the operator an electric shock.
Wear eye protection. It is also recommended to use protective equipment for hearing, head, hands, legs and feet. Ade-
quate protective equipment will reduce personal injury by contact with waste or accidental contact with the chain.
Do not operate the power saw on a tree, ladder, from the roof or on any unstable support. Working with the power saw while
on the tree may result in injuries.
Always maintain a proper posture and work with the power saw standing on a still, safe, and level surface. A slippery or
unstable surface, e.g., a ladder, may result in a loss of balance or control of the chainsaw.
Exercise caution in terms of a kickback when cutting a tensioned branch. If the tension accumulated in the wood fi bres is
released, the branch may strike the operator or make him/her lose control of the power saw.
Take special care when cutting shrubs and saplings. Slim material can catch the chain and push the power saw towards the
operator or unbalance him/her.
Handle the chainsaw by the front handle, turned o ff and away from the body. Always put on the chain guide bar guard
when transporting or storing the power saw. Correct holding of the power saw reduces the likelihood of accidental contact with
moving parts of the power saw.
Observe the instructions for lubricating and tensioning the chain, and changing accessories. An improperly tensioned or
lubricated chain can break and increase the chance of kickback towards the operator.
Keep handles dry, clean, and free of grease and oil. The greasy or grease-coated handles are slippery and cause control loss
of the chainsaw.
Cut wood only. The use of the power saw for purposes other than the intended is not allowed. For example: do not cut
plastic, concrete, or non-wooden construction materials. Using the chainsaw for works other than the intended may result
in dangerous situations.
This power saw is not designed to fell trees. Using the power saw for other work than the intended may cause serious injuries
to the operator and bystanders.
Observe all instructions when removing jammed material, storing or servicing the power saw. Make sure that the power
switch is in the o ff position and that the battery is disconnected from the tool. Unexpected start-up of the power saw when
removing jammed material or servicing may result in serious injuries.
Causes and prevention of kickback towards the operator.
A kickback towards the operator may occur when the guide bar’s end is in contact with an object or the cut wood jams the power
saw in the kerf. In some cases, contact between the end of a guide bar and an object can cause a violent reaction driving the guide
bar up and towards the operator. Jam in the guide bar upper edge kerf can suddenly direct the guide bar towards the operator.
These reactions can result in a loss of control of the power saw, leading to serious injuries. Do not rely only on safety elements built
in the power saw. The power saw operator should take some steps to prevent accidents and injuries during work.
A kickback towards the operator is the result of improper use or incorrect operating procedures or conditions. This can be avoided
by taking the appropriate precautions listed below:
Keep a fi rm grip of both hands with thumbs and fi ngers closing around the chainsaw handles. The position of the body
and shoulders should allow withstanding forces arising during the kickback. If appropriate precautions are taken, the kick-
back forces can be controlled by the operator. Do not allow the power saw to move freely.
Do not reach too far and cut above shoulder height. This will help prevent unintentional contact with the end of the guide bar
and allow better control of the power saw during unexpected situations.
Use guide bar and chain substitutes only as speci fi ed by the manufacturer. Incorrect guide bar and chain substitutes may
cause chain breakage or kickback.
Observe the instructions given by the manufacturer regarding the chain sharpening and maintenance. Reducing the depth
of the chain guide bar slot can lead to an increased probability of kickback.
Other safety instructions
It is forbidden to expose the power saw to precipitation and use it in an atmosphere of increased humidity. It is also forbidden to
use the power saw in an atmosphere with an increased risk of fi re or explosion.
Avoid contact with grounded, conductive, and non-insulated objects such as pipes, radiators, or refrigerators during operation.
When not in use, store the power saw in a dry and closed room inaccessible to unauthorised persons.
Use the cutting chain adapted to the given load. Do not use cutting chains designed for light or heavy-duty work.
Always wear protective gloves when replacing, repairing, and adjusting the cutting chain.
Make sure that the power saw has been disconnected from the power supply during transport. Disconnect the mains-powered
power saws from the socket. In the case of the battery-powered power saws, disconnect their battery. A guide must be fi tted on
the cutting chain guide bar. Handle the power saw with the guide bar pointing back.
Do not handle the mains-powered power saw by its power cord. Do not disconnect the plug from the socket by pulling the power cord.
Avoid accidental starting of the power saw. When handling the power saw connected to the mains or with the battery connected,
keep your fi ngers away from the power switch.
Always wear suitable protective clothing adhering to the body.
