9. Working instructions

Working with brush cutter / grass trimmer
• When you work with the petrol brush cutter for the
first time, familiarize yourself with the operation
and control of the petrol cutting blade without run-
ning engine.
• The design of the petrol brush cutter allows for op-
eration only at the right side of the user's body.
• Keep the petrol brush cutter firmly with both hands
on the handles.
• Always make sure that the cutting tool continues to
rotate briefly after the throttle has been released.
• Always so that the cutting tool no longer turns in a
proper engine idle not press down the throttle.
• Always work with high speed so you have the best
cutting results.
• Poke when working on a stone or a tree, turn off
the engine and remove the spark plug then exam-
ine the petrol brush cutter for damage.
• Caution: Always be extra careful when working in
difficult terrain and slopes. Cut tall grass gradually
so as not to overload the unit.
• Always wear safety glasses and hearing protection
and a safety helmet.
• Use the cutting blade to comb through brushwood,
rank growth, young tree populations (trunk diam-
eter of maximum 2 cm), and high grass.
• 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 cut-
ting tool is from the ground, the higher is the risk that
objects to be cut and particles will be hurled side-
ways.
Mowing with grass trimmer
• Use the plastic line cassette for a clean cut also at
uneven edges, fencing posts, and trees.
• Carefully advance the trimming line to an obstacle,
and use the tip of the line to cut around the ob-
stacle. When the trimming line comes into contact
with stones, trees, and walls, the line wears out or
breaks off ahead of time.
• 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.
Working with hedge trimmer
• The hedge trimmer may be used only for cutting
hedges, bushes and shrubs
• Hold the hedge trimmer with both hands on a safe
distance from the body.
• 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.
• Due to its double sided knives the hedge trimmer
can be guided forward and backward or by oscillat-
ing movements from one to another side.
• At first cut the sides of the hedge and then the up-
per edge.
• Cut the hedge from the bottom up.
• 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.
• Remove unconditionally any foreign objects out of
the hedge (e.g. wires) as these can damage the
knives of the hedge trimmer.
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 lu-
bricant.
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.
