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.
5.7 Operating instructions
m
Important notices
• Exclusively use the device for sawing wood. Do not
work on metal, plastic, masonry and building materials
which are not made of wood.
• Turn off the motor if the saw comes in contact with for-
eign objects. Check the saw and, if applicable, repair it.
• Protect the chain from dirt and sand. Even small quan-
tities of dirt can quickly make the chain blunt and in-
crease the risk of kickback.
• Start by cutting up smaller logs to practise in order
to get a feel for the device, before attempting difficult
tasks.
• Activate the throttle at maximum, before starting saw-
ing.
• Press the casing of the chainsaw against the log when
starting sawing.
• Run the device at full throttle throughout the whole
sawing process.
• Let the saw do the work. Only use slight downwards
pressure.
• Release the throttle as soon as you have finished 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 after the
chain exits the wood, you should not apply any pres-
sure to the saw towards the end of the cut.
• Turn off the device before putting it down.
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 severe in-
juries. 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 because 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.

• Watch out for broken or dead branches that may fall
down and cause severe injuries.
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 sloping
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 be-
come blunt.
Undercut and felling the tree (Fig. B-C)
• For the undercut, first 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
direction when falling.
m NOTICE
Before completing the dropping cut, if required, in-
crease the cut using wedges to control the direction
of the fall. Exclusively use wood or plastic wedges.
