Using cutting blades
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
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.
Using the mowing head with nylon line
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.
