- Secure round timber.

- When working on slopes, always work facing the

slope.

- For performing crosscuts the toothed ledge (Z,

Fig. 12) must be applied to the timber to be cut.

- Before performing a crosscut firmly apply the toothed

ledge to the timber, only then can the timber be cut

with the chain running. For this the electric chain

saw is lifted at the back handle and guided with the

tubular handle. The toothed ledge serves as a center

of rotation. Continue by slightly pressing down the

tubular handle and simultaneously pulling backwards

the electric chain saw. Apply the toothed ledge a little

bit deeper and once again lift the back handle.

- The sawing device must be running whenever you

remove the electric chain saw from the timber.

- When performing several cuts the electric chain saw

must be switched off in between.

- When the timber must be pierced for cutting

or longitudinal cuts are to be performed it is

urgently recommended to have these works

carried out by specially trained persons only

(high risk of kickbacks).

- For performing longitudinal cuts (Fig. 13) apply

the sawing device at an angle which is as small as

possible. Be very careful when carrying out this kind

of work because the toothed ledge cannot be used.

- When cutting with the bottom edge of the bar the

electric chain saw may be pushed in the direction

of the user if the chain is clamped. For this reason

use the top edge of the bar whenever possible. The

electric chain saw will then be pushed away from your

body. (Fig. 14)

- If the timber is not free of tension (Fig. 15), first cut

the pressure side (A). Then the crosscut can be

performed on the tension side (B). Thus clamping of

the bar is avoided.

- Be very careful when cutting splintery wood. Cut

pieces of wood may be pulled along (risk of injuries).

- Never use the electric chain saw for lifting up or

removing pieces of wood or other objects.

- When releasing the tension the electric chain saw

should be supported on the trunk (risk of kickbacks).

- Tension releasing works must be carried out by

trained persons. High risk of injuries.

- Be aware of branches under tension. Do not cut free

branches from below.

- Never perform tension releasing works standing on

the trunk.

- Do not use the electric chain saw for works in the

forest, i. e. for cutting down trees or carrying out

tension releasing works. The user’s mobility and

safety necessary for this kind of work are not

guaranteed due to the cable connection.

CAUTION:

Do not fell or debranch trees unless you are

specially trained for it! There is a high risk of

injury! Make sure to follow local regulations.

- Before cutting down a tree ensure that

a) only those persons are within the working range

which are actually involved in cutting down the tree

b) all persons involved in the felling have an

unhindered retreat route (the retreat path should

be about 45° diagonally and to the rear away from

the direction of fall). Be aware of the increased risk

of stumbling from electric cables!

c) the bottom part of the trunk is free from foreign

bodies, underbrush and branches. Make sure to

have a safe footing (risk of stumbling).

d) the next working place is at least 2 1/2 tree lengths

away. (Fig. 16) Before cutting down the tree

check the direction of fall and make sure that there

are neither other persons nor any objects within a

distance of 2 1/2 tree lengths. (Fig. 16)

Felling direction

= Danger zone

= Retreat path

- Judging the tree:

Direction of hanging - loose or dry branches - height

of the tree - natural hang over - is the tree rotten?

- Take into account the direction and the velocity of the

wind. If strong gusts are occuring, do not perform any

cutting down works.

- Cutting the roots:

Start with the strongest root. First perform the vertical

and then the horizontal cut.

- Notching the trunk (A, Fig. 17):

The notch determines the direction of fall and guides

the tree. The trunk is notched perpendicular to the

direction of fall and penetrates 1/3 -1/5 of the trunk

diameter. Perform the cut near the ground.

- When correcting the cut always do so over the whole

width of the notch.

- Cut down the tree (B, Fig. 18) above the bottom edge

of the notch (D). The cut must be exactly horizontal.

The distance between both cuts must be approx. 1/10

of the trunk diameter.

- The material between both cuts (C) serves as a

hinge. Never cut it through, otherwise the tree will fall

without any control. Insert felling wedges in the cut (B,

Fig. 18) in good time.

- Secure the cut only with wedges made of plastic or

aluminium. Do not use iron wedges.

- When cutting down a tree always stay sideways of the

falling tree.

- When withdrawing after having performed the cut

down be aware of falling branches.

- When working on a sloping ground the user of the

electric chain saw must stay above or sidewards of

the trunk to be cut or the already cut down tree.

- Be aware of trunks which may roll towards you.

Kickback

- When working with the electric chain saw dangerous

kickbacks may occur.

- Kickback occurs when the tip of the blade(especially

the top quarter) inadvertently comes into contact with

wood or other solid objects. (Fig. 19)

- In this case the electric chain saw is thrown without

any control and with high energy potentials in the

direction of the user (risk of injuries).

In order to prevent kickbacks follow the indicated

instructions:

- Never apply the end of the bar when starting to make

a cut. Always observe the end of the bar.

- Never use the bar end for sawing. Be careful when

continuing to cut.

- When starting to perform a cut the chain must be

running.

- Ensure that the chain is always sharpened correctly.

Pay special attention to the hight of the depth limiter

(for detailed information see the chap. “Sharpening

the saw chain”).

- Never cut several branches at the same time. When
