RULES FOR SAFE OPERATION
WARNING DANGER
All models trinuners and brushcutters can
throw
small stone , metal or small objects as well
as the material being cut. Read these”Rules
for Safe Operation”With care.
Follow the instructions in your operator’s
manual.
WARNING DANGER
In addition to head, eye, face and ear
protectors shoes to protect your feet
improve your footing on slippery surfaces.
Do not wear ties, jewelry, or loose, dangling
clothing which could be caught in the unit.
Do not wear open-toed footwear, or go bare
foot or bare legged. In certain situations you
must wear total face and head protection.
Pay attention not to kick back and blade
thrust.
Read the operator’s manual carefully. Be thoroughly
familiar with the controls and proper use of the unit.
Know how to stop the unit and shut off the engine.
Know how to unhook a harnessed unit quickly.
Never allow anyone to use the unit without proper
inslruction.Be sure the operator wears the foot, leg,
eye, face and hearing protection. Do not rely on the
debris shield on the unit to protect your eyes from
ricocheting or thrown objects. Keep the area clear of
bystanders, children and pets. Never allow children
to oper ate or play with the unit.
Do not allow anyone to enter the operating
DANGER ZONE with you. The danger zone the
danger zone wear eye protection from thrown
objects. If the unit must be used where there are
unprotected people, operate at a low throttle speed
to reduce the risk of thrown objects.
Move the stop switch to “stop” position when the
engine idles, insure it reliable before cutting. Only
may continue to operate the unit when stop switch
is in good condition.
Routines for checking that the cutting attachment
stops turning when the engine idles.
11
CUTTING WITH A BLADE
SCYTIITNG WEEDS. This is cutting by swinging the
blade in a level arc. It can quickly clear areas of field
grass and weeds. Scything should not be used to cut
large, tough weeds or woody growths.
NOTE
Do not use a brush blade to cut trees which
exceed a diameter of 112 to 3/4 inches.
Scything can be done in both directions, or just in
one way which results in the debris being thrown
away from you.
That is using the side of the blade that it is rotating
away from you. Tilt down the blade slightly on
this same side .You will be hit by some debris if you
scythe in both directions.
SAWING This must be done with a saw blade when
the weeds are too thick and strong for scything.
If kickback occurs, the blade may be dull, or the
material so thick and hard that you should use a saw
blade instead of the brush blade.
Growth up to 3-inches in diameter, which is too thick
for scything, may be cut by sawing. Sawing requires
judgement on your part whether to cut on the side
where the blade pulls away from you but throws
back the debris ,or on the side where the debris
is thrown away from you but the reaction is push
which could become a kickout(blade thrust).
Always cut on the side of the tree which will cause
the tree to fall away from the unit. A kickout or
bind may result if the tree falls toward the unit and
pinches the blade.
Do not force the blade to cut. Do not change the
angle of cut after into the wood. Avoid using any
pressure or leverage which could cause the blade
to bind or crack.
