WORK TECHNIQUES
Basic working techniques
Always slow the engine to idle speed after each working opera-
tion. Long periods at full throttle without any load on the engine
can lead to serious engine damage. It is recommended that the
engine not be operated for longer than 1 minute at full throttle
with no load.
Grass trimming using a trimmer head
Hold the trimmer head just above the ground at an angle. It is the
end of the trimmer line that does the work. Let the trimmer line
work at its own pace. Never press the trimmer line into the area to
be cut.
The trimmer line can easily remove grass and weeds up against
walls, fences, trees and borders, however it can also damage sen-
sitive bark on trees and bushes, and damage fence posts.
WORK TECHNIQUES
Reduce the risk of damaging plants by shortening the trimmer
line to 4-4 1/2 inches (10-12 cm) and reducing the engine speed.
When trimming you should use less than full throttle so that the
trimmer line lasts longer and to reduce the wear on the trimmer
head.
Clearing
The clearing technique removes all unwanted vegetation. Keep
the trimmer head just above the ground and tilt it. Let the end
of the trimmer line strike the ground around trees, posts, statues
and the like. CAUTION! This technique increases the wear on
the trimmer line.
The trimmer line wears quicker and must be fed forward more
often when working against stones, brick, concrete, metal fenc-
es, etc., than when coming into contact with trees and wooden
fences.
