Two types of cutting blades can be used for cutting, grass
cutting blade and brush knife. Never use grass cutting
blades to cut brushwood.
Grass cutting blade:
▪ A grass cutting blade is used to cut all kinds of tall
weeds;
▪ The grass is cut by swinging the brush cutter from side
to side like a scythe (scything motion), where the motion
from right to left is the cutting stage and the motion from
left to right is the return stroke. Avoid previously cut
green waste during the return stroke;
▪ If the blade is tilted to the left when brushing, the grass
builds up in a line, which makes it easier to catch;
▪ Let the support cup touch the floor gently. It is used to
protect the blade from touching the floor.
Brush knife:
▪ A brush knife is used to cut/trim brushwood, shrubs or
wild vegetation with a maximum diameter of 12mm;
▪ When you cut the brushwood or shrubs, place the blade
very close to the soil (as if cutting with a scythe);
▪ Cut wild vegetation from top to bottom by layers, keeping
the blade at a level below the user's waist. However,
when bigger the distance between the blade and the
ground, bigger the risk of flying particles. For this reason,
the user shall have extra attention when performing this
way;
▪ Always operate the brush cutter with the trigger fully
pressed to avoid the accumulation of debris in the blade
tip;
▪ Avoid contact of the blade with hard objects (rocks,
stones, tree trunks). Otherwise, the brush cutter may be
thrown violently in the opposite direction to the rotation
of the blade. You risk what's called kickout or blade
thrust. Kickout can be violent enough to make you lose
the control of the brush cutter.
Kickout may occur without warning. Blade kickout/thrust is
more likely to occur in areas where it is difficult to see the
material to be cut.
Blade thrust may also occur if you try to cut down
small trees, shrubs or bushes with a diameter greater
than that recommended by the manufacturer.
The mowing head with nylon line is used for cutting grass,
weeds or lawn.
Make sure that the nylon line is still firm and evenly rolled-
up in the reel, otherwise, the brush cutter will produce
harmful vibrations.
Only use mowing heads and nylon lines that have the
characteristics and dimensions recommended by the
manufacturer.
Never use wires or ropes instead of nylon line.
Otherwise, accidents and injuries may occur.
The length of the nylon line is also important. A longer line
requires more motor power than a shorter line with the
same diameter.
Make sure that the blade inside of the protective cover is
still intact and sharpened. The blade will cut the nylon line
to the correct length.
When the nylon line is worn out or cracks:
1. Place the mowing head on the floor and press gently the
spring in the inside to allow the nylon line to slide out;
2. The length of the cutting nylon line is defined by the
maximum length allowed for the blade.
