EYE PROTECTION
HEARING AND EAR PROTECTION
Prolonged exposure to loud noise can cause impairment
or loss of hearing.
The operator must wear eye protection not only against
objects thrown by the unit, but also because eye
infections can be caused by airborne dust, seeds and
pollen.
Wear a suitable hearing protective device such as
earmuffs or earplugs to protect against objectionable or
uncomfortable loud noises.
Prescription glasses may be worn under the safety
goggles.
Eye protection should also be worn by persons in the
risk zone which extends beyond the danger zone.
Hearing protectors
Safety goggles
Head and face protection
Shoulder harness
Trim-fitting clothes
Safety gloves
Sturdy shoes or boots
Long trousers
PROTECTIVE CLOTHING
ADDITIONAL PROTECTION
Hay fever (Rhinitis) sufferers may wear disposable
masks to help reduce the intake of allergenic particles.
Choose trousers, shirts and jackets that fit trimly and
have no strings, frills or dangling straps which could
catch on the unit or the underbrush. Do not wear ties,
loose clothing or jewellery. Keep clothing buttoned or
zipped up and shirt tails tucked in. Secure hair so it is
above shoulder length.
The wearing of gloves offers some protection against
contact with skin irritants such as poison ivy. Soft
leather work gloves may also improve your grip.

Do not raise the cutting attachment above knee height.
If raised higher, the cutting attachment will be more
directly in line with your face. Thrown objects may hit
your face and eyes.
Do not allow anyone to enter the operating DANGER
ZONE with you. The danger zone is an area of 15 m in
radius.
Insist that persons in the RISK ZONE beyond the
danger zone wear eye protection to protect them from
thrown objects. If the unit must be used where there are
unprotected people, operate at a low throttle speed to
reduce the risk.
Wear the recommended protective gear.
Never operate the unit without the proper guards,
shoulder harness and other protective devices.

Painful or numb fingers?
See your doctor immediatelty!
VIBRATION AND COLD
REPETITIVE STRESS INJURIES
It is believed that a condition called Raynaud’s Phenom-
enon which affects the fingers of certain individuals may
be brought about by exposure to vibration and cold.
Exposure to vibration and cold may cause tingling and
burning, followed by loss of colour and numbness in the
fingers.
It is believed that over-using the muscles and tendons of
the fingers, hands, arms and shoulders may cause
soreness, swelling, numbness, weakness and extreme
pain to the areas just mentioned. Certain repetitive hand
activities may put you at a high risk for developing a
repetitive stress injury (RSI).
The following precautions are strongly recommended
because the minimum exposure which might trigger the
ailment is unknown.
To reduce the risk of RSI, do the following:
• Avoid using your wrist in a bent, extended or twisted
position.
• Keep your body warm, especially the head and neck,
• Take periodic breaks to minimize repetition and rest
your hands. Reduce the speed and force in which
you do the repetitive movement.
feet and ankles, and hands and wrists.
• Maintain good blood circulation by performing
vigorous arm exercises during frequent work breaks,
and also by not smoking.
• Do exercises to strengthen hand and arm muscles.
• See a doctor if you feel tingling, numbness or pain in
your fingers, hands, wrists or arms. The sooner RSI
is diagnosed, the more likely permanent nerve and
muscle damage can be prevented.
• Limit the number of hours of operation.
Try to fill each day with jobs where operating the
trimmer 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 exposing yourself
further to cold and vibration.

SCYTHING WEEDS. This is cutting by swinging the
cutting attachment 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.
If a sapling or shrub binds the cutting attachment, do not
use the cutting attachment as a lever to free the bind,
because this will cause cutting attachment failure.
Instead, shut off the engine and push the sapling or
shrub to free the blades.
Do not use a cracked or damaged blade.

Anticlockwise rotation
Pull
Kickback
Push
KICKBACK. This may occur when the moving blade at
the front of the blade circle contacts strong brush or
trees. The force that occurs pushes the entire unit and
blade violently away in an arc. Kickback is a danger to a
bystander and also a jolting force to the operator.
REACTION FORCES
WARNING
DANGER
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.
PUSH. The operator may feel the unit push toward him
when he tries to cut the object on right. If he cannot hold
the blade in the cut, a kickback may occur when the
blade is pushed out to where the teeth at the outside
furthest point from the operator are cutting. The blade
will “kickback” sideways.
PULL. The opposite of push. When object on left, the
operator may feel the unit pull away. Although this pull
type of cutting may cause sawdust to be thrown back at
the operator, it is recommended for sawing off heavy
brush because the cutting is smoother and more stable
than when the unit pushes.

RULES FOR SAFE OPERATION
(WITH NYLON LINE CUTTING HEAD)
The basic cutting actions pictured are:
Trimming, scything, scalping and lawn edging.
These actions are as follows:
SCYTHING: This is the cutting or mowing of large
grassy areas by sweeping or swinging the trimmer in a
level arc. Use a smooth, easy motion. Do not try to hack
or chop down the grass. Tilt the line head or line disc to
direct the debris away from you on the scything stroke.
Then return without cutting grass for another stroke. If
you are well protected and do not care whether some
debris is thrown in your direction, you may scythe in
both directions.
TRIMMING: This is feeding the trimmer carefully into the
material you wish to cut. Tilt the head slightly to direct
the debris away from you. If cutting up to a barrier such
as a fence, wall or tree, approach from an angle where
any debris ricocheting off the barrier will fly away from
you. Move the line head or line disc slowly until the
grass is cut right up to the barrier, but do not jam
(overfeed) the line into the barrier. If trimming up to wire
mesh or chain link fencing, be careful to feed only up to
the wire. If you go too far, the line will snap off around
the wire.
Trimming can be done to cut through weed stems one at
a time. Place the nylon line cutter 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.
Debris
Cut on this side
Nylon line head or disc
rotates anticlockwise.
The knife will be on the
left side of the shield.
Scalping
Edging
SCALPING AND EDGING: Both of these are done with
the line head or line disc tilted at a steep angle. Scalping
is removing top growth, leaving the earth bare. Edging is
trimming the grass back where it has spread over a
pavement or driveway. During both edging and scalping,
hold the unit at a steep angle in a position where the
debris, and any dislodged dirt and stone, will not come
back towards you even if it ricochets off the hard
surface.
For nearly all cutting, it is good to tilt the nylon cutter so
that contact is made on the part of line circle where the
line is moving away from you and the shield (See
appropriate picture). This results in the debris being
thrown away from you.
Tilting the head to the wrong side will shoot the debris
toward you. If the nylon line cutter is held flat to the
ground so that cutting occurs on the whole line circle,
debris will be thrown at you, drag will slow the engine,
and you will use up a lot of line.
Although the pictures show how to edge and scalp,
every operator must find for himself the angles which
suit his body size and cutting situation.
WARNING
DANGER
USE ONLY FLEXIBLE, NON-METALLIC LINE
RECOMMENDED BY KIORITZ CORPORATION.

Line pushed into wire
fencing will snap off.
Do not trim near cars or pedestrians.
Do not push the line into tough weeds, trees, or wire
fences. Pushing the line into chicken wire, chain link
fencing or thick brush can result in snapped-off line
ends being hurled back at the operator. The proper way
is to cut right up to a barrier, such as any of those
mentioned, but never run the line into or through the
obstruction. Do not cut closely to obstruction or barrier.
WARNING
DANGER
USE EXTREME CAUTION WHEN OPERATING
OVER BARE SPOTS AND GRAVEL, BECAUSE

RICOCHET OFF HARD SURFACES.
WARNING
DANGER
Always wear proper eye protection against thrown
objects. Objects can bounce up at you from the ground
under the shield, or ricochet off any nearby hard
surface.
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. INJURY CAN OCCUR IF A
JAM IS REMOVED AND THE CUTTING
Do not trim at high speed near roadways when there is
traffic, or in places where there are pedestrians. If you
must trim where people are in the zone of risk use a
much lower or reduced speed, by using a partial trigger
setting. Do not use full throttle.

CARBURETTOR ADJUSTMENT
COOLING SYSTEM MAINTENANCE
IMPORTANT
WARNING
DANGER
To maintain proper engine operating temperature,
cooling air must pass freely through the cylinder
fin area. This flow of air carries combustion heat
away from the engine.
WHEN CARBURETTOR ADJUSTMENT IS
COMPLETED, CUTTING ATTACHMENT SHOULD
NOT MOVE AT IDLE, OTHERWISE SERIOUS
PERSONAL INJURY MAY RESULT.
Overheating and engine seizure can occur when:
Every unit is test run at the factory and the carburettor is
fine tuned for maximum performance.
Before adjusting carburettor, clean or replace air filter, start
engine and run several minutes to bring it to operating
temperature.
• Air intakes are blocked, preventing cooling air
from reaching the cylinder,
or
To adjust the carburettor proceed as follow:
1. Trun the low speed mixture adjuster (L) and high
speed mixture adjuster (H) anticlockwise to stop.
2. Start engine and turn “idle” speed adjustment screw
(T) clockwise until the cutting attachment begins to
turn, then turn the screw (T) anticlockwise until the
cutting attachment stops turning. Turn screw (T)
anticlockwise an additional 1/4 turn.
3. Accelerate to full throttle for 2 to 3 seconds to clear
excess fuel from engine then return to idle. Accelerate
to full throttle to check for smooth transition from idle to
full throttle.
• Dust and grass build up on the out side of the
cylinder. This build-up insulates the engine and
prevents the heat from leaving.
Removal of cooling passage blockages or
cleaning of cylinder fins is considered “Normal
Maintenance”. Any resultant failure attributed to
lack of maintenance is not warranted.
•
•
Remove dust and dirt from between fins.
Before each use, remove accumulated debris from
bottom engine intake grille located between the fuel
tank and starter.
CAUTION
When starting, idle speed adjuster (T) should be
adjusted not to rotate the cutting attachment.
When there is some trouble with the carburettor,
contact your dealer.

CHECKING THE BLADE
•
•
•
Use only the blade designated for this model by the
manufacturer.
•
•
When the cutting blade becomes dull due to wear
reverse it for further use.
When a crack is noticed on the blade, do not use it
but replace with a new one.
When chip or bend occurs on the blade, vibration will
increase.
Replace with a new one.
Ensure that the blade is correctly fitted in accordance
with the instructions.
•
When filing the blade file 3 cutting edges evenly
using a flat file as shown in the illustration.
Otherwise, the balance will be lost and vibration will
increase.

CHECKING THE NYLON LINE CUTTING
ATTACHMENT
(1) Make sure each periphery of the 2 retaining pawls of
housing spreads almost fully up to the outer periphery
of the respective cover window.
(4) Inspect cover and tap knob for wear.
When slot appears on bottom of the tap knob or when
slot appears on cover bottom close to outlet for Nylon
line, replace them with new parts without fail.
(2) Check mount of cutting head on trimmer and tighten if
it is loose.
(5) Check the cutting head for crack or chip.
Replace parts that show any crack or chip with new
ones without fail.
(3) Check the cutter head for deflection or abnormal noise
rotating it by hand.
Deflection or abnormal noise can cause abnormal
vibration to occur or mount to trimmer to loosen during
rotation which is dangerous.
