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:
 Follow the previous cutting tips;
 for 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).
Caution: Before performing any work on the unit:
– Switch off the engine.
– Wait until all moving parts have come to standstill;
the engine must have cooled down.
– Remove spark-plug terminal from the engine to prevent
the engine from starting unintentionally.
Have all repairs carried out by a repair shop only.
At the end of the season have the unit inspected and
serviced by a specialist company.
Installing the cutting line
Always use a replacement cutting line which has a diameter
of 2.41 mm and a maximum length of 4.5 m. If using
a cutting line which has a length other than the one
indicated, the engine may overheat or misfire.
Note: The line can be installed on a spool which has either
been removed from or is mounted on the unit.
1. Remove any residual line from the spool (Fig. 25).
– Turn the bump knob (1) anti-clockwise (in direction of
arrow on the spool) until both ends of the line have
disappeared in the spool housing (Fig. 25a).

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.
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.
