If two or more people are involved in the cutting and

felling, the distance between those who are felling

and cutting should be at least twice the height of the

tree to be felled. When felling trees, make sure that

other people are not put at risk, that supply lines are

not hit and that no material damage is caused. If a

tree comes in contact with a supply line, the supply

company has to be notied immediately.

Look for decay and rot. If the trunk is rotted, it may

suddenly collapse and fall on you. Make sure there is

enough space for the tree to fall safely. Keep a dis-

tance of 2 1/2 tree lengths from the nearest person or

other objects. Engine noise can drown out a warning

call.

Remove dirt, stones, loose bark, nails, staples, and

wire from the tree where you are going to cut.

Keep an escape route (Fig. A)

Before felling, an escape route has to be planned

and cleared, if necessary. The escape route should

lead diagonally away from the back of the falling tree

(Fig. A).

Item 1: Plan of emergency exits

Item 2: Position in which the tree falls

Felling of large trees - only with appropriate train-

ing (15 cm in diameter)

Fell large trees using the notch method. Here, a

wedge is laterally cut out of the tree according to the

desired direction of fall. After a cut has been made

on the case of the other side of the tree, the tree will

fall in the direction of the wedge.

Note: If the tree has large prop roots, they should be

removed before making the notch. If the saw is used

to remove the prop roots, the chain should not touch

the ground, to prevent it from becoming become

blunt.

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

• Saw a wedge with a depth of 1/3 of the tree diam-

eter at a right-angle to the falling direction. Make

the lower horizontal wedge cut rst (Fig. B, No. 1).

This will prevent the saw chain or the guide bar be-

coming jammed when the second wedge cut (Fig.

B, No. 2) is made. Now remove the excised wedge.

• Next, you can run the felling cut (Fig. B, Pos. 3) on

the opposite side of the tree. Do this at approxi-

mately 5 cm above the centre of the notch. Make

the dropping cut parallel to the horizontal wedge

cut. For the dropping cut (No. 3), saw only to a

depth so that a bridge (No. 4) (holding wood) re-

mains which can act as a hinge. The bridge pre-

vents the tree from turning and falling in the wrong

direction. Do not cut through the bridge.

Make sure your work-piece is rmly secured. Use

clamps to stop the work-piece slipping. This also

makes it easier to operate the chainsaw with both

hands. Kick-back causes the saw to behave uncon-

trollably and thus brings with a slack or blunt chain.

A poorly sharpened chain increases the risk of kick-

back. Never saw above shoulder height.

Operation - tips on chain saw use

Important Notes

• Use the device exclusively for sawing wood. Do

not cut metal, plastics, masonry, building material

that is not made of wood, etc.

• Turn off the engine when the saw comes into con-

tact with a foreign object. Inspect the saw and re-

pair it if necessary.

• Protect the chain from dirt and sand. Even a small

amount of dirt will quickly blunt a chain and in-

crease the risk of kickback.

• Start by cutting a few small logs, using the exercise

to get a feel for your device before you tackle more

difcult tasks.

• Press the casing of the chain saw against the log

when you start sawing.

• Allow the saw to work. Exert only slight downward

pressure.

• In order not to lose control of the device you should

lean towards the end of the incision so there is no

pressure on the saw.

Felling Trees – Only after appropriate training

Caution: Watch for broken or dead branches that

could fall during sawing and cause serious injury. Do

not saw near buildings or electrical wires if you do

not know in which direction the felled tree could fall.

Do not work at night since you will not be able to see

properly, or in rain, snow or storm, as it is difcult to

predict the direction in which the tree could fall.

• Plan your work in advance.

• The work area around the tree should be clear so

you have a rm foothold.

• The operator should always stand on the uphill

side of the terrain as the tree is expected to roll or

slide after felling.

• Check for broken or dead branches, which can fall

and cause serious injury.

The following conditions may affect the direction

in which a tree falls:

• Wind direction and speed.

• Lean of the tree. The inclination is not always vis-

ible due to uneven or sloping terrain. Determine

the lean of the tree using a solder or a spirit level.

• Branch growth (and hence weight) on one side

only.

• Surrounding trees and obstacles.
