• While using metal cutting tools, there is generally
a risk of recoil, when the tool hits a solid obstacle
(stones, trees, branches, etc.). Thereby, the tool is
hurled backwards against the rotating direction.
• To cut rank growth and brushwood, you "immerse" the
cutting blade from the top.
CAUTION: Be especially careful, when using this
working technique, because the further away the cutting
tool is from the ground, the higher is the risk that objects
to be cut and particles will be hurled sideways.
Angle adjustment
By swivelling the cutter head, the hedge trimmer can be
adjusted to the working conditions from +90° to -75°. Fig. 49.
• Warning! Adjust the angle only when the motor has
been turned off.
• Push both levers down and put the cutter head in the
required position. Fig. 48
• Release both levers until they click into place in the notch.
• Before use, check that the adjustment levers have
clicked into place properly. Fig. 49
Oil the blades and the angle adjustment each time before
starting work, with environmentally friendly lubricant.
Regularly oil the blades during working hours as well.
Warning! Oil the tool only when the motor has been
turned off.
CAUTION: Incorrect use and misuse can damage the
bush cutter and cause severe injuries because of pieces
hurled away.
To minimize the risk of accidents by use of the cutting
blade, take note of following points:
• Never cut shrubbery or wood whose diameter is larger
than 2 cm.
• Avoid contact with metal bodies, stones, etc.
• Periodically check the cutting blade for damages.
Never continue to use a damaged cutting blade.
• When the cutting blade becomes apparently blunt, it
must be sharpened according to instructions. When
the cutting blade is apparently out of balance, it must
be replaced.
Working with pole saw
Oiling of the chain and bar
It is recommended to use commercial chain oil.
Remove the oil tank cap. (Fig.54 / L)
Fill the chain oil tank (Fig.54 / M )) to 80% with chain oil.
Close Oil tank cap (Fig.54 / L)
Oil Supply Control
Always make sure the automatic oiler system is working
properly. Keep the oil tank filled with Chain, Bar and
Sprocket Oil.
Adequate lubrication of the bar and chain during cutting
operations is essential to minimize friction with the guide
bar.
Never starve the bar and chain of lubricating oil. Running
the saw dry or with too little oil will decrease cutting
efficiency, shorten saw chain life, cause rapid dulling
of chain, and lead to excessive wear of bar from
overheating. Too little oil is evidenced by smoke or bar
discoloration.
To check the saw chain lubrication, hold the chain saw
with the saw chain over a piece of paper and give a few
seconds of full throttle.
The oil quantity can be checked on the paper. The chain
must always be thrown off a small amount of oil. After a
few seconds, a light oil trail must be visible.

Fine adjustment Fig 61.
Use screw (R) to reduce or increase the amount of oil.
Clockwise - oil quantity is reduced (-)
Counterclockwise - oil quantity increases (+)
Precautions for Saw procedure
Never stand under the branch you want to saw. Use special
caution when working with branches under tension and
splintering wood. Possible risk of injury caused by falling
branches and catapulting pieces of wood. In general, it is
recommended to set the pruning saw at an angle of 60 ° to
the road.
Keep both hands well with the device during the cutting
process and pay you up to an equilibrium position and a
good level.
• Never try to use your tool with 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.
• Never cut with the upper edge or the tip of the cutter bar.
• Make sure that the chain tension is always correctly
adjusted.
• Practice for guiding the device slight pressure, but you do
not overload the motor.
Clear the work area before
branches and undergrowth.
a retreat area, far from the spot where the cut
branches fall on, and remove any obstacles there.
Keep the work area clean, remove the cut branches
immediately. Pay attention to your point, wind direction and
the possible direction of fall of the branches. Be prepared
that fallen branches can strike back. Place all other tools
and equipment at a safe distance from the branches to be
cut, but not in the retreat area.
Always observe 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 down
unexpectedly during cutting.
You could also attend by fractured and dead branches
out, which is solved by the shake and fall on you.
For very thick or heavy branches you first make a small
incision below the branch before you work from the top
down to avoid chipping.
Basic cutting technique
Heavy branches break off easily when sawing. They tear
long strips of bark away from the trunk, which damages
the tree sustainably. The following section technique can
