Grass trimming with a trimmer head
„ Trimming
● 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 sensitive bark on trees
and bushes, and damage fence posts.
● Reduce the risk of damaging plants by shortening
the trimmer line to 10-12 cm (4-4,75 in) 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. IMPORTANT: 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 fences, etc., than when
coming into contact with trees and wooden fences.
„ Cutting
● The trimmer is ideal for cutting grass that is difficult
to reach using a normal lawn mower. Keep the
trimmer line parallel to the ground when cutting.
Avoid pressing the trimmer head against the ground
as this can ruin the lawn and damage the tool.
The life span of the machine can be reduced and the
risk of accidents can increase if machine maintenance
is not carried out correctly and if service and/or repairs
are not carried out professionally. If you need further
information, please contact your nearest authorized
service dealer.
Unit/Maintenance Safety
Disconnect the spark plug before performing
maintenance, except carburetor adjustments.
a
WARNING:
The complete clutch, clutch cover,
and shaft must be fitted before the machine is
started, otherwise parts could come loose and
cause personal injury.
● 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 line can be used for
quick and easy clearing up. Hold the trimmer line
parallel to and above the area to be swept and
move the tool back and forth.
● When cutting and sweeping you should use full
throttle to obtain the best results.
a WARNING:
machine nor anyone else may attempt to remove
the cut material while the engine is running or
the trimmer line is rotating, as this can result in
serious injury. Stop the engine and trimmer head
and disconnect lead from spark plug before you
remove material that has wound around the drive
shaft as otherwise there is a risk of injury. The
bevel gear can get hot during use and may remain
so for a while afterwards. Allow time to cool. You
could get burned if you touch it.
a WARNING:
Always wear eye protection. Never lean over the
cutting attachment guard. Stones, rubbish, etc.
can be thrown up into the eyes causing blindness
or serious injury.
a
WARNING:
at a distance. Children, animals, onlookers
and helpers should be kept outside the safety
zone of 15 meters (50 feet). Stop the machine
immediately if anyone approaches.

MAINTENANCE

Carburetor
„ Function
The carburetor governs the engine's speed via
the throttle control. Air and fuel are mixed in the
carburetor.
The T-screw regulates the throttle setting at idle
speed. If the T-screw is turned clockwise this gives a
higher idle speed; turning it counterclockwise gives a
lower idle speed.
„ Basic setting
The basic carburetor settings are adjusted during
testing at the factory. Fine adjustment should be
carried out by a trained technician.
