WORKING TECHNIQUES

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.

Sweeping

The fan effect of the rotating cord can be used for quick 
and easy clearing up. Hold the cord parallel to and above 
the area to be swept and move the tool to and fro.

When cutting and sweeping you should use full throttle to 
obtain the best results.
