WORKING TECHNIQUES
Grass clearing using a grass blade
•
Grass blades and grass cutters must not be used on
woody stems.
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.

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.

material.

Grass trimming with a trimmer head
Trimming
•
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.

Clearing
•
The clearing technique removes all unwanted vegetation.
Keep the trimmer head just above the ground and tilt it. Let
the end of the cord strike the ground around trees, posts,
statues and the like. CAUTION! This technique increases
the wear on the cord.

•
The cord wears quicker and must be fed forward more
often when working against stones, brick, concrete, metal
fences, etc., than when coming into contact with trees and
wooden fences.

•
When trimming and clearing you should use less than full
throttle so that the cord lasts longer and to reduce the
wear on the trimmer head.

Cutting
•
The trimmer is ideal for cutting grass that is difficult to
reach using a normal lawn mower. Keep the cord parallel
to the ground when cutting. Avoid pressing the trimmer
head against the ground as this can ruin the lawn and
damage the tool.

•
Do not allow the trimmer head to constantly come into
contact with the ground during normal cutting. Constant
contact of this type can cause damage and wear to the
trimmer head.

!
WARNING! Machines fitted with saw blades
or grass blades can be thrown violently to
the side when the blade comes into contact
with a fixed object. This is called blade
thrust. A blade thrust can be violent enough
to cause the machine and/or operator to be
propelled in any direction, and possibly lose
control of the machine. Blade thrust can
occur without warning if the machine snags,
stalls or binds. Blade thrust is more likely to
occur in areas where it is difficult to see the
material being cut.

Avoid cutting with the area of the blade
between the 12 o'clock and 3 o'clock
positions. Because of the speed of rotation
of the blade, blade thrust can occur if you
attempt to cut thick stems with this area of
the blade.
