•

Large stems must be cut from two sides. First determine 
which direction the stem will fall. Make the first cut on the 
felling side. Then finish cutting the stem from the other 
side. Adjust the cutting pressure to match the size of the 
stem and the hardness of the wood. Small stems require 
more pressure, while large stems require less pressure.

•

If the stems are tightly packed, adapt your walking pace to 
suit.

•

If the blade jams in a stem, never jerk the machine free. If 
you do this the blade, bevel gear, shaft or handlebar may 
be damaged. Release the handles, grip the shaft with 
both hands and gently pull the machine free.

•

Thin stems and brush are mown down. Work with a 
sawing movement, swinging sideways.

•

Try to cut several stems in a single sawing movement.

•

With groups of hardwood stems, first clear around the 
group. Start by cutting the stems high up around the 
outside of the group to avoid jamming. Then cut the stems 
to the required height. Now try to reach in with the blade 
and cut from the centre of the group. If it is still difficult to 
gain access, cut the stems high up and let them fall. This 
will reduce the risk of jamming.

•

Grass blades and grass cutters must not be used on 
woody stems.

•

A grass blade is used for all types of tall or coarse grass.

•

The grass is cut down with a sideways, swinging 
movement, where the movement from right-to-left is the 
clearing stroke and the movement from left-to-right is the 
return stroke. Let the left-hand side of the blade (between 
8 and 12 o’clock) do the cutting.

•

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.

•

Try to work rhythmically. Stand firmly with your feet apart. 
Move forward after the return stroke and stand firmly 
again.

•

Let the support cup rest lightly against the ground. It is 
used to protect the blade from hitting the ground.

•

Reduce the risk of material wrapping around the blade by 
following these instructions: 

1

Always work at full throttle.

2

Avoid the previously cut material during the return 
stroke.

•

Stop the engine, unclip the harness and place the 
machine on the ground before you start to collect the cut 
material.

•

Hold the trimmer head just above the ground at an angle. 
It is the end of the cord that does the work. Let the cord 
work at its own pace. Never press the cord into the area 
to be cut.

•

The cord can easily remove grass and weeds up against 
walls, fences, trees and borders, however it can also 
damage sensitive bark on trees and bushes, and damage 
fence posts.

•

Reduce the risk of damaging plants by shortening the 
cord to 10-12 cm and reducing the engine speed.
