- First press and then turn the oil adjustment screw (19) anti-
clockwise to increase chain lubrication.
9.5 Checking the chain brake
m WARNING
The chain brake must be checked before each use.
The chain brake brakes the saw chain immediately in the event
of kick-back.
• Make sure that the front hand guard (1) is free of dirt and
moves easily.
• Start the chainsaw as described under 9.1 and accelerate the
saw chain to full speed (full throttle).
• With the saw chain running, operate the front hand guard (1).
The chain brake must brake and lock the saw chain at max.
speed.
m WARNING
Increased engine speed for too long with the chain brake
locked will damage the engine and the chain drive.
If the saw chain (17) still moves, contact the customer service.
10. Basic working instructions for felling work
m WARNING
Danger of injury!
Sawing and felling work as well as all related work may only be
carried out by specially trained and briefed persons.
Note
Observe the country-specific regulations for felling work and
obtain information from the relevant authority.
• Make sure that no one can be harmed by the falling branches
and trees.
• Only the persons required for the felling work may be in the
work area.
• Keep the work area at the trunk clear and tidy so that opera-
tors have a safe standing area.
• Keep escape routes clear and tidy in order to be able to leave
the work area quickly.
• Do not carry out felling work in stronger wind conditions, bad
weather or poor visibility.
• Keep distances to the nearest workplace of at least 2 1/2 tree
lengths.
10.1 Use and handling
• Never start the device before the guide rail (16), saw chain
(17) and chain cover (22) are correctly fitted.
• Do not cut wood that is lying on the ground or try to cut roots
that are sticking out of the ground. In any case, make sure
the saw chain (17) does not come into contact with the soil,
otherwise the saw chain (17) will dull immediately.
• If you accidentally touch a solid object with the device, switch
off the engine immediately and inspect the device for any
damage.

• Maintain the device carefully. Check for misalignment or
binding of moving parts, breakage of parts and any other
condition that may affect the device's operation. Have dam-
aged parts repaired before using the device. Many accidents
are caused by poorly maintained devices.
• Keep cutting tools sharp and clean. Properly maintained cut-
ting tools with sharp cutting edges are less likely to bind and
are easier to control.
• If a blockage occurs between the material to be cut and the
saw chain, then switch it off immediately. Wait until the saw
chain has come to a standstill. Remove the spark plug con-
nector and put on cut-resistant gloves to remove the block-
age.
• If the guide rail (blade) has to be removed, follow the instruc-
tions as described in the chapter "Installation". After re-
moving the blockage and re-installation, a test run must be
carried out. If vibrations or mechanical noises are detected
during this process, stop work and contact an authorised
service centre. Should this hazard occur more often, we rec-
ommend training.
• Have the device serviced by qualified personnel. Only use
manufacturer's recommended original spare parts.
10.2 Creating the notch cut
Note
The fall notch determines the felling direction of the tree to be
felled.
Place the fall notch at right angles to the felling direction.
Saw as close to the ground as possible.
Support the chainsaw with the claw stop (15).
10.2.1
Determining the felling direction - with marks on
the device (fig. G)
The chainsaw is equipped with felling marks (35) which aid you
with the direction of the chainsaw.
Place the chainsaw against the trunk. The felling marks (35)
show you the probable felling direction of the tree.
10.2.2
Creating the notch cut (fig. H)
• First start with the cut of the fall notch A. The depth of the fall
notch should be approx. 1/4 of the tree diameter and have an
angle of 45°- 60°.
10.2.3
Checking the felling direction (fig. I)
Place the chainsaw with the guide rail (16) at the bottom of the
notch cut.
The felling marks (35) show the probable felling direction.
If necessary, recut the notch cut accordingly.
10.3 Carrying out the felling cut (fig. H)
• Place the felling cut B approx. 2-3 cm higher than the hori-
zontal cut of the fall notch A. Make sure that felling cut B is
carried out exactly horizontally.
• Leave approx. 1/10 of the tree diameter, the breaking strip C
before felling cut B. Breaking strip C guides the tree to the
ground like a hinge and secures it against premature falling.
