using a plumb line or a level.

• Branches growing (and therefore weight) only on one

side

• Surrounding trees or obstacles

Look out for destroyed or decayed parts of the tree.

If the trunk is decayed, it can suddenly break and fall on

you. Make sure there is su󰀩cient space for the falling

tree. Keep a distance of 2½ tree lengths to the next per-

son or other objects. The sound of the motor can drown

out warning cries.

Remove dirt, stones, loose bark, nails, brackets and wire

from the sawing area.

m Ensure you have a free escape route (Fig. A)

Position 1: Escape route

Position 2: Falling direction of the tree

Felling of large trees - only with relevant training

(from 15cm diameter)

The undercutting method is used for felling large trees.

For this, a wedge is cut out from the side of the tree ac-

cording to the required falling direction. After the drop-

ping cut has been made on the other side of the tree, it

will fall in the direction of the wedge cut.

m NOTICE

If the tree has large prop/buttress roots, these should be

removed before the wedge is cut. If the saw is used for

removing the prop/buttress roots, the saw-chain should

not touch the ground so the chain does not become

blunt.

Undercut and felling the tree (Fig. B-C)

• For the undercut, rst cut the upper part (Pos. 1) of

the wedge (Pos. 2). Cut 1/3 of the way into the tree.

Then saw the lower part (Pos. 3) of the wedge (Pos.

2). Now remove the wedge you have cut out.

• Afterwards, you can carry out the dropping cut on the

opposite side of the tree (Fig. 4). For this, start about

5cm above the middle of the cut. In this way, there is

enough wood between the dropping cut (Pos. 4) and

the wedge (Pos. 2) so that it functions as a hinge. This

hinge is designed to guide the tree in the right direc-

tion when falling.

m NOTICE

Before completing the dropping cut, if required, increase

the cut using wedges to control the direction of the fall.

Exclusively use wood or plastic wedges. Steel or iron

wedges can cause kickback and damage to the device.

• Be aware of signs that the tree is beginning to fall:

Cracking sounds, the dropping cut opening or move-

ment in the upper branches.

• When the tree begins to fall, stop the saw, put it down

and leave immediately via your escape route.

• To prevent injuries, do not cut partly felled trees with

your saw. Beware especially of partly felled trees

which are not supported. If a tree does not fall down

completely, remove the saw and help the process

along with a cable winch, a pulley or a towing vehicle.

Sawing a felled tree (log division)

The term „log division“ describes the cutting up of a

felled tree into logs of the desired length.

m CAUTION

Do not stand on the log you are currently cutting. The log

could roll away and you may lose your footing and con-

trol of the device. Do not carry out sawing work on slop-

ing ground.

Important notices

• Only ever saw one log or branch.

• Be careful when cutting split wood. You may be hit by

sharp pieces of wood.

• Cut small logs or branches on a sawhorse. When cut-

ting logs, no other person must hold on to the log. Do

not secure the log with your leg or foot.

• Do not use the saw in areas where logs, roots and

other parts of the tree are entangled. Pull the logs to

a free area and cut the freed logs rst.

Di󰀨erent cuts for log division (Fig. D)

m CAUTION

If the saw is jammed in a log, do not pull it out with force.

You may lose control of the device and su󰀨er severe in-

juries and/or damage the saw.

Stop the saw and drive a plastic or wooden wedge into

the cut until the saw can be pulled out easily. Restart the

saw and carefully continue with the cut. Never start the

saw when it is jammed in a log.

Topping (Fig. E, Pos. 1)

Topping starts at the upper side of the log where you

hold the saw against the log. Only use slight downwards

pressure for topping.

Undercut (Fig. E, Pos. 2)

Start the undercut on the underside of the log and hold

the top edge of the saw against the log. Only use slight

upwards pressure for the undercut. Hold the saw secure-

ly to control the device. The saw will push backwards (in

your direction).

m CAUTION

Never hold the saw the wrong way round for an under-

cut. You do not have control of the device in this position.

Always make the rst cut on the compression side of the

log. The compression side of the log is where the pres-

sure of the log‘s weight is concentrated.
