12.4.3 Cutting lawn edges
• Go into the cut at least at half throttle and always cut at full
throttle.
• Always keep the device vertical when guiding it.
• Apply feed force such that the engine speed does not drop
significantly. Do not press with great force!
• Do not select a feed speed greater than your normal walk-
ing speed.
• Do not push the blade into the ground.
• Only push the unit forward and do not pull it towards you.
• Always cut evenly to avoid multiple operations.
12.5 Working with the pole-mounted pruner (36)
12.5.1 Automatic saw chain lubrication - fine
adjustment (fig. 13).
Fill the oil tank (44) (see 9.5.3)!
The amount of oil can be reduced or increased with the adjust-
ing screw (73).
• Clockwise - the amount of oil is reduced (-)
• Counterclockwise - the amount of oil is increased (+)
12.5.2 Checking the automatic saw chain lubri-
cation
• Always ensure that automatic saw chain lubrication is work-
ing properly.
• Ensure that the oil tank is always filled (44).
• During sawing work, the guide bar (41) and the saw chain
(40) must always be oiled sufficiently in order to reduce fric-
tion on the guide bar (41).
• The blade (41) and the saw chain (40) must never be with-
out oil. If you use the saw dry or with too little oil, the cutting
performance reduces, the service life of the blade (41) is
reduced, the saw chain (40) becomes blunt quicker and the
blade (41) wears a great deal due to overheating. You can
see that there is too little oil if smoke is produced or the blade
(41) or saw chain (40) discolours.
• To check the saw chain lubrication, hold the chainsaw with
the saw chain (40) over a sheet of paper and give it full throt-
tle for a few seconds.
• The oil quantity can be checked on the paper. The saw chain
(40) must always fling a small amount of oil. After a few
seconds, a light oil trail must be visible.
12.5.3 Precautionary measures for the sawing
work
Never stand directly under the branch that you want to saw off!
Possible risk of injury caused by falling branches and catapult-
ing pieces of wood. In general, it is recommended to set the
pole-mounted pruner (36) at an angle of 60° to the branch.

Hold the device firmly with both hands during the cutting pro-
cess and always ensure that you are in a balanced position
and have secure footing.
• Never use the device with only one hand! The loss of control
of your tool can cause serious injury or death. Never work
on a ladder, a tree branch or other unstable surfaces.
• Do not saw strong branches in one cut, always in several
steps.
• Place the saw chain (40) on the branch to be cut.
• Apply light pressure to move the device, but do not overload
the engine.
Before cutting, clear the work area of obstructive branches and
undergrowth. Then, keep the area clean, on which branches
could fall after cutting and remove any obstacles there, if
necessary. Always keep the work area clear, remove the cut
branches immediately. Pay attention to your location, the wind
direction and the possible felling direction of the branches. Be
prepared for fallen branches to kick back. Place all other tools
and devices at a safe distance from the branches to be cut, but
not in the withdrawal area.
Always monitor the condition of the tree.
Look for rot and decay in the roots and branches. If they are
rotten inside, they can break off and fall unexpectedly while
cutting.
Also watch out for broken and dead branches that could come
loose due to the vibrations and fall on you.
For very thick or tough branches, first make a small cut beneath
the branch before working from top to bottom to prevent it
breaking off.
Basic cutting technique
Heavy branches break off easily when sawing and long strips
of bark break off from the trunk which causes lasting damage
to the tree. You can significantly reduce this risk with the follow-
ing cutting technique:
• First saw the branch about 10 cm away from the trunk on the
underside of the branch.
• 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 rec-
ommend sealing the cutting area with grafting wax.
Dangers from reactive forces
Reactive forces occur during the operation of the saw chain
(40). The forces that are to be applied to the wood act against
the operator. They occur when the moving saw chain (40)
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.
