• If necessary, the chain lubrication can be increased or de-
creased by means of the oil adjustment screw (19).
• Use the slotted screwdriver (31) supplied to help:
- First press and then turn the oil adjustment screw (19)
clockwise to reduce chain lubrication.
- 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 branch-
es 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 op-
erators 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 lying on the ground or try to saw roots
protruding from the ground. In any case, make sure the saw
chain (17) does not come into contact with the soil, other-
wise 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 acci-
dents are caused by poorly maintained devices.
• Keep cutting tools sharp and clean. Properly maintained
cutting 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, 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 in-
structions 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 more occur often, we rec-
ommend a new 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.
