Read and understand the
Examine other parts of the trimmer head and clean if
it is necessary.
To trim the grass
1. Hold the trimmer head immediately above the
ground at an angle. Do not push the trimmer line
into the grass. (Fig. 34)
2. Decrease the length of the trimmer line by 10-12
cm / 4-4.75 in.
3. Decrease the engine speed to decrease the risk of
damage to plants.
4. Use 80 % throttle when you cut grass near objects.
(Fig. 35)
To cut the grass
1. Make sure that the trimmer line is parallel to the
ground when you cut the grass. (Fig. 36)
2. Do not push the trimmer head to the ground. This
can cause damage to the product.
3. Move the product from side to side when you cut
grass. Use full speed. (Fig. 37)
To clear grass with a grass blade
1. Grass blades and grass cutters must not be used on
woody stems.
2. A grass blade is used for all types of tall or coarse
grass.
3. The grass is cut down with a sideways, swinging
movement, where the movement from right-to-left
is the clearing stoke and the movement from left-to-
right is the return stoke. Let the left-hand side of the
blade (between 8 and 12 o'clock) do the cutting.
4. if the blade is angled to the left when clearing grass,
the grass will collect in a line, which makes it easier
to collect, e.g. by raking.
5. Try to work rhythmically. Stand firmly with your feet
apart. Move forward after the return stoke and stand
firmly again.
6. Let the support cup rest lightly against the ground. It
is used to protect the blade from hitting the ground.
7. Reduce the risk of material wrapping around the
blade by always work at full throttle and avoid the
previously cut material during the return stoke.
8. Stop the engine, unclip the harness and place the
machine on the ground before you start to collect the
cut material.
