OPERATING MANUAL
HOLDING THE LAWN TRIMMER
Before using the unit, place yourself in the operating position
(Fig. 20). Check the following:
 The user is wearing eye protection and the correct
clothing.
 The shoulder belt has been set to the correct height.
 The handle bar has been set in such a way that you can
grip it with both hands without having to stretch out your
arms.
 The unit is below waist height.
 Hold the cutting attachment parallel to the ground
so that the vegetation to be cut can easily be reached
without the user having to bend forward.
ADJUSTING THE LENGTH OF THE TRIM LINE
You can release the trim line with the bump knob cutting
attachment without stopping the engine. To release more
line, tap the cutting attachment on the ground (Fig. 21) while
running the lawn trimmer at a higher speed.
NOTE: The trim line should always have the max. length.
The horter the trim line becomes, the more difficult
it is to release.
Each time the head is bumped, approx. 25 mm of cutting line
are released. If too much line is released, a blade in the
cutting attachment guard cuts the line back to the correct
length. It is best to bounce the bump head on bare ground
or hard earth. If you attempt to release the trim line in tall
grass, the engine may stall. Always keep the trim line fully
extended. The shorter the trim line is, the more difficult it is
to release.
NOTE: The line spool should not touch the ground during
operation (cutting process).
The line may break by:
 becoming entangled with foreign objects
 normal material fatigue
 attempting to cut thick-stalked weeds
 striking walls, garden fences, etc.
TIPS FOR BEST TRIM RESULTS
 Keep the cutting attachment parallel to the ground.
 Use only the tip of the line for cutting, especially along
walls. If more than the tip is used for cutting, the cutting
capacity is reduced and the engine may overload.
 Cut grass which is taller than 20 cm from the top down
in small stages to prevent premature wear of the line and
engine resistance.
 If possible, cut from left to right. Cutting to the right
improves the cutting capacity of the unit. Grass clippings
are then ejected by the user.
 Slowly move the lawn trimmer at the required height
in and out of the cutting area. Walk either forwards
and backwards or from side to side. Better results are
achieved by cutting shorter pieces.
 Cut dry grass and weeds only.
The service life of the cutting line depends on the following:
 on following the previous cutting tips;
 on the vegetation which is to be cut;
 where it is cut.
For example, a line wears out more quickly if it is cutting
against a house wall than around a tree.
DECORATIVE CUTTING
You will receive a decorative cut if you cut all vegetation
around trees, posts, fences, etc.
Rotate the whole unit until you are holding the cutting
attachment at an angle of 30° to the ground. (Fig. 22).
WORKING WITH THE CUTTING BLADE
Before operating the unit, please place it in the operating
position (Fig. 20). See “Holding the lawn trimmer.”
Tips for working with the cutting blade:
Cut rhythmically:
 Stand firmly but comfortably on the ground.
 Before you start cutting, set the unit to full speed. At full
speed the blade has maximum cutting force and will
therefore not jam so easily, stick or cause blade impacts
which may result in serious injury to the user or other
persons.

When cutting, move the upper part of your body from
right to left.
 Always release the throttle and reduce the engine
to no load when you are not cutting.
 Rotate the unit in the same direction in which the blade
is cutting. This promotes cutting.
 Move one or two steps to the next trimming area after
swinging back the unit and stand firmly again.
 The blade features a second cutting side which can
be used by removing the blade, turning it round and
reinstalling it.
Follow these instructions to prevent vegetation from
wrapping itself around the blade:
 Cut at full speed.
 Swing from right to left into the vegetation which
is to be cut (Fig. 23).
 When swinging back, avoid vegetation which has
just been cut.
