Safety

■

Do not work with the chain saw in a tree.

Risk of injury when operating in a tree.

■

Always make sure you are standing firmly

and only use the chain saw if you are

standing on firm, secure and level ground.

Slippery ground or unstable standing surfac-

es such as on a ladder can lead to a loss of

equilibrium or loss of control over the chain

saw.

■

When cutting a branch that is under ten-

sion, expect it to spring back. When the

tension in the wood fibres is released, the

branch under tension can hit the operator

and/or cause a loss of control over the chain

saw.

■

Take particular care when cutting under-

growth and young trees. The thin material

can get caught in the saw chain and hit you

or cause you to lose your balance.

■

Carry the chain saw at the front grip when

it is switched off, and have the saw chain

pointing away from your body. Always put

on the protective cover when transporting

or storing the chain saw. Careful handling

of the chain saw reduces the probability of in-

advertent contact with the running saw chain.

■

Follow the instructions for lubrication,

chain tensioning and changing accesso-

ries. An incorrectly tensioned or lubricated

chain can either tear or increase the risk of

kickback.

■

Keep the grips dry, clean and free from oil

and grease. Greasy, oily grips are slippery

and result in loss of control.

■

Only saw wood. Do not use the chain saw

for work for which it is not intended. Ex-

ample: Do not use the chain saw for saw-

ing plastic, masonry or construction ma-

terials that are not made of wood. Using

the chain saw for non-designated work can

lead to dangerous situations.

3.9 Causes and prevention of kickback (EN

60745 Part 2-13)

Kickback can occur if the tip of the chain bar

touches an object or if the wood bends and traps

the saw chain during cutting.

In many cases, contact with the tip of the bar can

lead to an unexpected, rearward reaction causing

the chain bar to be knocked upwards and to-

wards the operator.

If the saw chain is trapped on the top edge of the

chain bar, the bar can be forced rapidly back to-

wards the operator.

Each of these reactions can result in you losing

control of the saw, with the possibility of severe

injury. Do not rely entirely on the safety devices

installed on the chain saw. As user of a chain

saw, you should take various measures to be

able to work without accident and injury.

Kickback is the consequence of incorrect or faulty

use of the electric tool. It can also be prevented

by taking suitable precautions as described be-

low:

■

Hold the saw firmly with both hands, with

your thumb and fingers around the grips

of the chain saw. Hold your body and

arms in a position that allows you to with-

stand the kickback forces. If suitable mea-

sures are taken, the operator will be able to

control the kickback forces. Never release

the chain saw.

■

Avoid any abnormal posture, and do not

saw anything above shoulder height. This

will avoid inadvertent contact with the tip of

the bar, and allow better control of the chain

saw in unexpected situations.

■

Always use replacement bars and saw

chains prescribed by the manufacturer. In-

correct replacement bars and saw chains can

lead to the chain breaking and/or to kickback.

■

Comply with the instructions of the manu-

facturer for sharpening and maintaining

the saw chain. Depth limiters set too low in-

crease the tendency to kickback.

3.10 Safety instructions for the polemounted

pruner

3.10.1 Work instructions (13)

■

During pruning, lift the polemounted pruner

(13/1) to a maximum angle of 60° (13/2). At a

steeper angle, you inevitably get into the area

where cut-off branches can fall. Always stand

outside this area.

■

Plan an escape route in advance for getting

out of the way of falling branches. This es-

cape route must be free of obstacles such as

sawn-off branches or slippery places that

could hinder getting out of the way.

■

Keep a safe distance from bystanders, ani-

mals, objects or buildings, which is at least

approx. 2.5x the length of the branch to be

sawn off. If that is not possible, saw the

branch off piece by piece.
