4. Use full throttle when you move the product from

side to side (Picture 39) to cut grass. Make sure that

the grass trimmer line is parallel to the ground.

TTo 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.
