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
H
Courses in the use of chain saws and
techniques for felling trees are regularly
held by various forestry organisations.
A
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.
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.
34
■ 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).
