• 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 cas
-
sette 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 hedge trimmer
• Use the hedge trimmer to comb through brush-
wood, rank growth and young tree populations
• Hold the string trimmer at a safe distance away
from your body with two hands.
• 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.
• Thanks to the its double­sided cutting unit, the string
trimmer can be moved forward and backward or from
one side to the other swinging it back and forth.
• Cut the sides of the hedges first and then the top
edge.
• Cut the hedges from bottom to the top.
•
Cut the hedge in trapezium shape. This prevents the
lower hedge area from becoming bare due to insuf-
ficient light.
• 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.
• Make sure to remove any foreign objects from the
hedges (e.g. wire), since it may damage the cutting
unit of the hedge cutters.
• Attention! The blades are still running! Do not stop
the blades with your hand.
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
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.
• Hold the operating handle with your right hand and
the handle on the shaft with your left hand.
• 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.
• Move the device with a uniform curved movement
from left to right and back again. Then cut the next
section. Fig. 39
Attention: Always move the device back into the
original position before cutting the next path.
• 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 diameter
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. This chops the ma-
terial to be cut
• Attention! The cutting unit is still running! Do not
stop the cutting unit with your hand.
• Keep the cutting unit of the string trimmer away
from feet.
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.
