• Never replace the nylon line with a metal wire.
RISK OF INJURIES
Automatic thread trimming (Fig. 36)
The petrol cutting blade is delivered with a filled line
cassette. This line will wear out during work. To feed new
line, forcefully press the head of the line cassette onto the
ground while the engine is running at working speed.
The line is automatically fed due to centrifugal force.
The knife at the line guard will shorten the trimming line to
the correct length. Run the trim line approach cautiously
to an obstacle and cut with the tip of the line around the
obstacle.
Mowing with brush cutter and hedge trimmer
Use the cutting blade to comb through brushwood,
rank growth, young tree populations (trunk diameter of
maximum 2 cm), and high grass.
• The maximal diameter to cut depends on the wood's type,
age, moisture and hardness.
• Therefore cut very thick branches using branch shears to
your desired length before trimming the hedge.
• 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.
• Cut the hedge in trapezium shape.
• Stretch a guide over the complete length of the hedge
when you want to shorten the upper edge of the hedge
evenly.
• Trim in several passes if you have to cut down a large
portion of the hedge.
• To cut rank growth and brushwood, you "immerse"
the cutting blade from the top.
Best time for hedge trimming:
• Leaved hedge: June and October
• Conifer hedge: April and August
• Quickly growing hedge: from May and then every 6
weeks
Pay attention to breeding birds in the hedge. If so, put off
hedge trimming or leave this area out.
Angle adjustment
By swivelling the cutter head, the hedge trimmer can be
adjusted to the working conditions from +90° to -75°. Fig. 42.
• 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. 41
• Release both levers until they click into place in the notch.
• Before use, check that the adjustment levers have
clicked into place properly. Fig. 42
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: 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.
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.47 / L)
Fill the chain oil tank (Fig.47 / M )) to 80% with chain oil.
Close Oil tank cap (Fig.47 / L)
Oil Supply Control
Always make sure that the automatic oil system is
working properly. Always ensure the oil tank is full.
During sawing work, the guide and the chain must
always be sufficiently oiled to reduce friction with the
chain bar.
The chain bar and the chain must never be without oil. If
you operate the chain dry or with too little oil, the cutting
performance will decrease, the service life of the chain
bar will reduce, the chain will become blunt quickly and
the guide will wear rapidly owing to overheating. You can
detect a lack of oil from smoke development or the guide
changing colour.
To check the chain lubrication keep the chain on a
piece of paper and give full throttle for a few seconds.
On the paper the quantity of oil can be checked.The
saw chain must always throw off a little oil. After a few
seconds, a slight oil trace must be visible.
Make sure that there is always enough oil in the tank
because chain lubrication is always on.

You can reduce or increase the quantity of oil using the
screw (S).
Clockwise - oil quantity is reduced (-)
Anti-clockwise - oil quantity is increased (+)
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
