• Make another cut about 15 cm to the trunk from above.
• Keep sawing until the branch breaks off. There is now no longer a risk
of damaging the bark on the trunk.
• Finally, remove the remaining branch stump with a clean cut from
above along the trunk.
• To keep the damage to the tree to a minimum, we also recommend
sealing the cutting area with grafting wax.
Dangers from reactive forces
Reactive forces occur during the operation of the saw chain (31). The
forces that are to be applied to the wood act against the operator. They
occur when the moving saw chain (31) comes into contact with a solid
object such as a branch or is jammed. These forces can lead to a loss of
control and injuries.
Understanding how these forces occur can help you avoid the moment
of shock and loss of control.
This saw is designed so that the kick-back effects are not as noticeable as
with conventional chainsaws.
Nevertheless, always make Container you have a firm grip and secure
footing so that you can keep control of the tool in case of doubt.
The most common effects are:
• Kick-back
• Recoil
• Kick-back
Kick-back
Kick-back can occur if the running saw chain (31) strikes a solid object
on the upper quarter of the blade (32) or becomes jammed.
The cutting force of the saw chain (31) exerts a rotational force on the
saw in the opposite direction to the saw chain movement. This leads to
an upward movement of the blade (32).
Avoid kickback
The best protection is to avoid situations that lead to kickbacks.
• Always keep an eye on the position of the upper guide rail.
• Never let this point come into contact with an object. Do not cut any-
thing with it. Be particularly careful in the vicinity of wire fences and
when cutting small, hard branches that can jam the saw chain (31)
easily.
• Only cut one branch at a time.
Kick-back
Retraction occurs when the saw chain (31) suddenly becomes stuck on
the underside of the blade because it is jammed or hits a foreign object
in the wood. The saw chain (31) then pulls the saw forwards.
Retraction often occurs when the saw chain (31) is not running at full
speed when it comes into contact with the wood.
Avoiding retraction
Be aware of the forces and situations that can lead to the saw chain (31)
becoming jammed on the underside of the blade (32). Always start cut-
ting with the saw chain (31) running at full speed.
Recoil
Recoil occurs when the saw chain (31) suddenly becomes stuck on the
top of the blade because it is jammed or hits a foreign object in the wood.
The saw chain (31) can then suddenly push the saw towards the operator.
Recoil often occurs when the top of the blade is being used for cutting.

Avoiding recoil
Be aware of the forces and situations that can lead to the saw chain (31)
becoming jammed on the top of the blade. Do not cut more than one
branch at a time. Do not tilt the blade (32) to the side when pulling it out
of a cutting slit, as this could jam the saw chain (31).
13. Transport (Fig. 2/3)
If you want to transport the device, empty the fuel tank (see 10.3.1).
Clean coarse dirt from the device using a brush or a hand brush.
Always attach the protective cover (15a, 21 and 34) to the cutters when
not in use, during transport or storage.
The device must be secured against tipping and slipping during transport
in vehicles in order to prevent damage and injuries.
14. Maintenance
ATTENTION:
Always wear protective gloves during all work on and around the cutting tools.
Always attach the protective cover (21 and 34) to the cutters when not
in use, during transport or storage.
Always shut the engine down and remove the spark plug connector (6)
before carrying out any maintenance and cleaning work.
• Do not spray the device with water. This damages the engine.
• Clean the device with a cloth, hand brush, etc.
• Use a damp cloth to clean the plastic parts. Do not use cleaning
agents, solvents or sharp objects.
• When using the trimmer / grass trimmer (12), for technical reasons
wet grass and weeds wrap around the drive axle beneath the shield
(14) while working. Remove this, otherwise the engine will overheat
due to excessive friction. (Fig. 18)
Clean and maintain the device before storing it.
14.1 Regular checks
Note that the following information relates to normal use.
Under certain circumstances (longer daily work, heavy levels of dust,
etc.), shorten the intervals specified accordingly.
Before starting work, after filling the tank, after an impact or if dropped:
• Check the cutting tools for firm seating, general visual inspection for
cracks and damage.
• Replace damaged or blunt cutting tools immediately, even with hair-
line cracks.
• Sharpen the cutting tools (also if necessary).
Weekly check:
• Gear lubrication (also if necessary).
If necessary:
• Tighten the accessible fastening screws and nuts.
Excessive wear and damage to the device can be prevented if the speci-
fications in this user manual are adhered to.
