Storage

3. Projecting pin (18/2) defines the correct posi-

tion of the quick-tension chain wheel. Make

sure it is correctly seated.

STORAGE

Thoroughly clean the chain saw after each use.

Store it in a dry, lockable place out of the reach

of children.

Carry out the following jobs before intervals in

work lasting for longer than 30 days:

1. Switch off the machine and disconnect the

mains plug.

2. Unscrew the oil tank cap.

3. Empty the oil tank.

4. Fill with some engine oil.

5. Run the chain saw with this for a short time in

order to flush the oil lines and oil pump.

6. Remove the saw chain and guide rail, clean it

and spray it with rust-proofing oil.

7. Thoroughly clean the chain saw and store it

in a dry place.

WORKING BEHAVIOUR AND WORKING

TECHNIQUE

Felling trees

Take the following measures before starting fel-

ling work.

■ Make sure that no other people, animals or

objects are in the danger area.

■ The safe distance from other workplaces or

objects should be at least 2% tree lengths.

■ Watch out for power lines and other people's

property. If necessary, notify the power sup-

ply company or the property owner.

■ Judge the falling direction of the tree.

Factors influencing the falling direction of the

tree:

■ Natural lean of the tree

■ Height of the tree

■ Branches growing on one side

■ Level ground or slope

■ Asymmetrical growth, wood damage

■ Wind direction and wind speed

■ Snow load

■ When working on a slope, always work uphill

of the tree to be felled.

■ Establish your escape route in advance, and

make sure that there are no obstacles in the

way. The escape route should be at an angle

of approx. 45° backwards from the falling di

rection (19).

■ The trunk must be free from growth, branches

and foreign bodies (e.g. dirt, stones, loose

bark, nails, staples, wire, etc.).

Make two undercuts and one back cut in order to

fell a tree.

1. During back cuts and cross-cuts, place the

bumper spike firmly against the wood to be

cut.

2. Saw the first undercut (20/C) horizontally,

then the second undercut at an angle of at

least 45° from above. This prevents the chain

saw becoming trapped when you make the

second undercut. The undercut must be as

close as possible to the ground and in the re-

quired felling direction (20/E). The depth of

the undercut should be about 1/4 of the dia-

meter of the trunk.

3. Cut the back cut (20/D) exactly horizontally

opposite to the undercut. The back cut must

be made 3-5 cm above the horizontal under-

cut.

4. Saw in the back cut (20/D) sufficiently deep

so that a bridge (20/F) of at least 1/10 the

trunk diameter remains between the undercut

(20/C) and the back cut (20/D). This bridge

prevents the tree from twisting and falling in

the wrong direction. The tree should start to

fall when the back cut (20/D) approaches the

bridge (20/F).

Courses in the use of chain saws and

techniques for felling trees are regularly

held by various forestry organisations.

DANGER!

Danger of injury due to inadequate tech-

nical knowledge!

Inadequate technical knowledge can re

sult in serious and even fatal injuries!

Only trained and experienced people are

allowed to fell trees and lop branches.

DANGER!

• Danger of fatal injury from splintered

wood!

Wood chips caught up in the chain can

lead to extremely serious and even fatal

injuries!

Remove loose chips and wood splinters

from the part to be sawn.
