łIt is believed that a condition called Reynaud’s phenomenon, which
affects the fingers of certain individuals may be brought about by
exposure to vibration and cold, loss of color and numbness in the
fingers. The following precautions are strongly recommended
because the minimum exposure which might trigger the ailment is
unknown. Keep your body warm, especially the head, neck, feet,
ankles, hands and wrists. Maintain good blood circulation by
performing vigorous arm exercises during frequent work breaks and
also by not smoking. Limit the hours of operation. Try to fill each day
with jobs where operating the brush cutter or other hand-held power
equipment is not required.
If you experience discomfort, redness and swelling of the fingers
followed by whitening and loss of feeling, consult your physician
before further exposing yourself to cold and vibration.
łAlways wear ear protection, loud noise for long time can make
hearing debase even lost hearing.
łTotal face and head protection must be wearing to prevent damage
from plummet or branch.
łWear no-slip heavy duty work gloves to improve your grip on the
brush cutter handle. Gloves also reduce the transmission of machine
vibration to your hands
łWARNING: The cutter area is still dangerous while the machine is
coasting to a stop.

WARNING
DANGER
CUTTING WITH A NYLON HEAD
TRIMMING:
This is feeding the trimmer carefully into
the material you wish to cut. Tilt the head
slowly to direct debris away from you. If
cutting up to a barrier such as fence, wall
or tree, approach from an angle where
any debris ricocheting off the barrier will
fly away from you, Move the line head
slowly until the grass is cut right up the
barrier, but do not jam (overfeed) the line
into the barrier. If trimming up to a wire
mesh or chain linked fence be careful to
feed only up to wire. If you go to far the
line will snap off around the wire.
Use only quality nylon monofilament
line of the diameter 2 mm. Never
use wire or wore-reinforced line in
place of nylon trimmer line. Load
your nylon line cutting head only
with ny n trimmer
lo
WARNING DANGER
Use extreme caution when operating
over bare spots and gravel, because
the line can throw small rock
particles at high speeds. Debris
shields on the unit cannot stop
objects which bounce or ricochet off
hard surfaces.
WARNING DANGER
The proper debris shield must be in
place on the unit when nylon
cutting line is used, The cutting line
can flap around if too much line is
exposed. Always use the plastic
debris shield with cut-off knife
when using nylon cutting heads.

Trimming can be done to cut through
weed stems one at a time. Place the
trimmer line head near the bottom of the
weed-never high up which could cause
the weed to chatter and catch the line.
Rather than cut the weed right through,
just use the very end of the line to wear
through the stem slowly.
WARNING DANGER
Don’ttouseasteelbladeforedgingorscalping.
SCALPING AND ENGING:
Both of these are done with the line head
tilted at a steep angle Scalping is removing
top growth leaving the earth bear.
Edging is trimming the grass back where it
has spread over a sidewalk or drive way.
During both edging and scalping, hold the
unit a steep angle and in a position
where the debris, and any dislodging dirt
and stones, will not come back towards
you even if it ricochets off the hard surface.
Although the picture shows how to edge and
scalp every operator must find for himself
the angles which suits his body size and
cutting situation.
