non which affects the fingers of certain individuals may be
brought about by exposure to vibration and cold. Expo-
sure to vibration and cold may cause tingling and burning,
followed by loss of colour and numbness in the fingers.
The following precautions are strongly recommended be-
cause the minimum exposure which might trigger the ail-
ment is unknown.

For safe use of your product
WARNING
Remove foreign objects and obstructions before working with the
product
Before starting work, check the area where you will be working and re-
move any small stones and empty cans likely to ricochet off the cutting
attachment, as well as any pieces of string or wire that might become
twisted around the cutting attachment.
An accident or serious injury can occur if foreign objects ricochet off the cut-
ting attachment or wire and other materials twisted round the product spring
off it.
Do not hold the cutting attachment up when working with the product
Do not hold the cutting attachment up while you work. You must not work with the cutting attachments raised above
knee level.
Raising the cutting attachment above knee level bringsthe plane of rotation closer to the face, and any objects that flyoff the
cutting attachments could cause an accident or serious injury.
Turn off the engine immediately if anything goes wrong
In the following situations, turn off the engine immediately and ensure that the cutting attachments have stopped be-
fore checking each area of the product. Replace any damaged parts.
If the cutting attachment hits a rock, tree, post, or other such obstruction while you work.
If the product suddenly starts to vibrate abnormally.
Continuing to use parts when they are damaged could lead to an accident or serious injury.
Kickback
The phenomenon that occurs if the trimmer blade
comes into contact with a tree, post, rock or other hard
object while rotating at high speed and reacts by recoil-
ing powerfully and instantaneously is known as kick-
back.
Causing kickback can result in a loss of control overthe
product and is highly dangerous.
In particular, if the front-right quadrant of the trimmer
blade (B) strikes a shrub or other such object, the trim-
mer blade will cause the product to recoil sharply back-
wards to the right.
To prevent kickback, do not trim from left to right. Be
careful to ensure that the trimmer blade does not strike
any hard objects.
When trimming, ensure that the object you are cutting
meets the portion of the blade 1/3 in from thefront edge
on the left-hand side (A).
Failure to do so could cause an injury or fatal accident.

12
For safe use of your product
Precautions concerning the cutting attachment
1.With metal blade
2.With nylon line cutting head
DANGER
Always stop the engine when a cutting attachment jam occurs. Do not attempt to remove an object causing a jam if the
engine is running. Severe injury can occur if a jam is removed and the cutting attachment suddenly starts.
WARNING
Use correct blades
Serious injury may result from the improper use of
blades.
Read and comply with all safety instructions listed in
this manual.
The 3 cutter blade is designed especially to cut weeds
and grass. To avoid injury due to kickback or blade frac-
ture, do not use the 3 cutter blade to cut brush or trees.
Use only cutting attachments recommended by KIOR-
ITZ CORPORATION.
Damaged or shattered blades can cause accidents and se-
rious injury.
Inspect blade before use
Pieces from a cracked metal blade can fly off during oper-
ation. Inspect metal blades for cracks before each use.
Discard cracked blades no matter how small the crack.
Cracked blades can be the result of the misuse or improp-
er sharpening.
Damaged or shattered blades can cause accidents and se-
rious injury.
Reaction forces
Be sure you understand the reaction forces of push and
pull, and kickback described in this manual, and how
these forces may affect your balance in the operation of a
unit.
Failure to do so could cause an injury or fatal accident.
WARNING
Use correct cutting attachment
Serious injury may result from the improper use of cut-
ting attachment.
Read and comply with all safety instructions listed in
this manual.
Use only cutting attachments recommended by KIOR-
ITZ CORPORATION.
Use only nylon line cutting head. Do not use any type of
metal blade.
Failure to do so could lead to an accident or serious injury.
Excessive nylon line beyond cut off knife could fly off
when the nylon line cutting head starts rotating after ad-
justment of nylon line length.
Failure to do so could lead to an accident or injury.
Do not trim near cars or pedestrians
Use extreme caution when operating over bare spots and
gravel, because the line can throw small rock particles at
high speeds. The shield on the unit cannot stop objects
which bounce or ricochet off hard surfaces.
Failure to do so could lead to an accident or serious injury.
Avoid wire
Do not trim in any area where there are broken strands of
fencing wire. Remove the broken pieces of wire, or give the
area wide berth. Wear proper safety protection. Do not cut
where you cannot see what the cutting device is cutting.
Failure to do so could lead to an accident or serious injury.
CAUTION
Use only flexible, non-metallic line recommended by KIORITZ CORPORATION.
