m WARNING
Fumes from fuel and solvents can cause explosions.
After repairs and maintenance work, re-attach the
safety devices to the machine.
Ensure the machine is operational, in particular,
check the fuel system for leak-tightness.
Always clear the motor's cooling fins of contamina-
tion.
m DANGER
m The manufacturer of this equipment shall be not li-
able to the applicable Product Liability Act for dam-
ages arising in this device or this unit at:
• Installation and replacement of non-original spare
parts,
• Removal or alteration of safety components.
5.7 Operating instructions
m Important notices
Turn off the motor if the saw comes in contact
1)
with foreign objects. Check the saw and, if ap-
plicable, repair it.
Protect the chain from dirt and sand. Even small
2)
quantities of dirt can quickly make the chain
blunt and increase the risk of kickback.
Start by cutting up smaller logs to practise in or-
3)
der to get a feel for the device, before attempt-
ing difficult tasks.
Activate the throttle at maximum, before start-
4)
ing sawing.
5) Press the casing of the chainsaw against the log
when starting sawing.
Run the device at full throttle throughout the
6)
whole sawing process.
Let the saw do the work. Only use slight down-
7)
wards pressure.
8) Release the throttle as soon as you have fin-
ished your work so the motor runs idle. If you let
the machine run at full throttle without load, there
will be unnecessary wear and tear.
So that you do not lose control of the device
9)
after the chain exits the wood, you should not
apply any pressure to the saw towards the end
of the cut.
10) Turn off the device before putting it down.
Check after starting the idle setting. The cutting
11)
blade must be stationary during idling.

Felling trees - only with relevant training
m CAUTION
Watch out for broken or dead branches which may
fall down during sawing and which could cause se-
vere injuries. Do not saw close to buildings or power
lines if you do not know in which direction the felled
tree will fall. Do not work at night because you can
see less well, or during rain, snow and storms be-
cause the direction in which the tree will fall cannot
be anticipated.
• Plan your work with the chainsaw in advance.
• The working environment around the tree should
be cleared so you have secure footing.
• The machine operator should always be positioned
at a higher level in the working area because the
tree will probably roll or slide down after felling.
The following conditions can influence the tree's
falling direction:
• Wind direction and speed
• Leaning of the tree - The leaning direction cannot
always be recognised because of uneven or slop-
ing ground. Determine the leaning direction of the
tree 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 sufficient space
for the falling tree. Keep a distance of 2½ tree lengths
to the next person 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 according to the required falling direction. After
the dropping 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.
