GENERAL SAFETY RULES

WARNING:

READ AND UNDERSTAND ALL INSTRUCTIONS.

Failure to follow all instructions listed below may result in

electric shock, fire and/or serious personal injury.

READ ALL INSTRUCTIONS

 For safe operation, read and understand all instructions

before using this product. Follow all safety instructions.

Failure to follow all safety instructions listed below, can

result in serious personal injury.

 Do not allow children or untrained individuals to use this

unit.

 Do not start or operate the engine in a confined space,

building, near open windows, or in other unventilated

space where dangerous carbon monoxide fumes can

collect. Carbon monoxide, a colorless, odorless, and

extremely dangerous gas, can cause unconsciousness

or death.

 Clear the work area before each use. Remove all objects

such as rocks, broken glass, nails, wire, or loose string

which can be thrown or become entangled in the cutting

line or blade.

 Always wear eye protection with side shields marked to

comply with ANSI Z87.1 along with hearing protection

when operating this equipment. Failure to do so could

result in objects being thrown into your eyes and other

possible serious injuries.

 Wear heavy, long pants, long sleeves, boots, and gloves.

Do not wear loose fitting clothing, short pants, sandals,

or go barefoot. Do not wear jewelry of any kind.

 Heavy protective clothing may increase operator fatigue,

which could lead to heat stroke. During weather that is

hot and humid, heavy work should be scheduled for early

morning or late afternoon hours when temperatures are

cooler.

 Never operate this unit on the operator’s left side.

 Secure long hair above shoulder level to prevent

entanglement in moving parts.

 Keep all bystanders, children, and pets at least

50 ft. away. Bystanders should be encouraged to wear

eye protection. If you are approached, stop the engine

and cutting attachment. In the case of bladed units, there

is the added risk of injury to bystanders from being struck

with the moving blade in the event of a blade thrust or

other unexpected reaction of the saw.

 Do not operate this unit when you are tired, ill, upset, or

under the influence of alcohol, drugs, or medication.

 Do not operate in poor lighting.

 Keep firm footing and balance. Do not overreach.

Overreaching can result in loss of balance or exposure

to hot surfaces.

  Do not use on a ladder, rooftop, tree, or other unstable

support. Stable footing on a solid surface enables better

control of the unit in unexpected situations.

 Keep all parts of your body away from any moving part.

 To avoid hot surfaces, never operate the unit with the

bottom of the engine above waist level.

 Do not touch area around the muffler or cylinder of the

unit, these parts get hot from operation. Contact with hot

surfaces could result in possible serious personal injury.

 Always stop the engine and remove the spark plug wire

before making any adjustments or repairs except for

carburetor adjustments.

 Inspect the unit before each use for loose fasteners, fuel

leaks, etc. Replace any damaged parts before use.

 Never use blades, flailing devices, wire, or rope on trim-

mer attachment. Never use flailing devices, wire, or rope

on any attachment.

 The cutting attachment should never rotate at idle during

normal use. The cutting attachment may rotate at idle

during carburetor adjustments.

 It has been reported that vibrations from hand-held tools

may contribute to a condition called Raynaud’s Syndrome

in certain individuals. Symptoms may include tingling,

numbness, and blanching of the fingers, usually apparent

upon exposure to cold. Hereditary factors, exposure to

cold and dampness, diet, smoking, and work practices

are all thought to contribute to the development of these

symptoms. It is presently unknown what, if any, vibrations

or extent of exposure may contribute to the condition.

There are measures that can be taken by the operator to

possibly reduce the effects of vibration:

a) Keep your body warm in cold weather. When operating

the unit wear gloves to keep hands and wrists warm.

It is reported that cold weather is a major factor

contributing to Raynaud’s Syndrome.

b) After each period of operation, exercise to increase

blood circulation.

c) Take frequent work breaks. Limit the amount of

exposure per day.

d) Keep the tool well maintained, fasteners tightened,

and worn parts replaced.

If you experience any of the symptoms of this condition,

immediately discontinue use and see your physician about

these symptoms.

 Store fuel in a container approved for gasoline.

 Wipe up any fuel spillage. Move 30 ft. away from refueling

site before starting engine. Slowly remove the fuel cap

after stopping engine. Do not smoke when refueling.

 Stop the engine and allow to cool before refueling or

storing the unit.

3 — English

SPECIFIC SAFETY RULES

 Inspect before use. Replace damaged parts. Make sure

fasteners are in place and secure. Check for fuel leaks.

 Replace string head if cracked, chipped, or damaged

in any way. Be sure the string head or blade is properly

installed and securely fastened. Failure to do so can cause

serious injury.

 Make sure all guards, straps, deflectors, and handles are

properly and securely attached.

 Use only recommended or equivalent replacement line in

the cutting head. Do not use any other cutting attachment.

To install any other type of replacement line or cutting

head to this string trimmer can result in serious personal

injury. Never use, for example, wire or wire-rope, which

can break off and become a dangerous projectile.

 Never operate unit without the grass deflector in place

and in good condition.

 Maintain a firm grip on both handles while trimming. Keep

string head below waist level. Never cut with the string

head located over 30 in. or more above the ground.

 This product is intended for infrequent use by homeowners

and other occasional users for such general applications

as trimming light and heavy vegetation, etc. It is not

intended for prolonged use. Prolonged periods of

operation can cause circulatory problems in the

user’s hands due to vibration. For such use, it may be

appropriate to use a product having an anti-vibration

feature.

 Save these instructions. Refer to them frequently and use

them to instruct others who may use this tool. If you loan

someone this tool, loan them these instructions also.

GENERAL SAFETY RULES

 Allow the engine to cool; empty the fuel tank, and secure

the unit from moving before transporting in a vehicle.

 Wear your protective equipment and observe all safety

instructions. For units equipped with a clutch, be sure

the cutting attachment stops turning when the engine

idles. When the unit is turned off make sure the cutting

attachment has stopped before the unit is set down.

 We recommend taking your equipment to a qualified

service center for repair, as service performed by

inexperienced or unqualified persons may damage the

equipment, create unsafe conditions, injury to user and/

or void your warranty.

OPERATING THE TRIMMER

See Figure 9.

WARNING:

Engine housing can become hot during trimmer operation.

Do not rest or place your arm, hand, or any body part

against the engine housing during trimmer operation.

Only hold the trimmer as shown in figure 9 with all body

parts clear of engine housing. Extended contact with

the engine housing can result in burns or other injuries.

WARNING:

Always position the unit on the operator’s right side. The

use of the unit on the operator’s left side will expose the

user to hot surfaces and can result in possible burn injury.

WARNING:

To avoid burns from hot surfaces, never operate unit with

the bottom of the engine above waist level.

Hold the trimmer with your right hand on the rear handle

and your left hand on the front handle. Keep a firm grip with

both hands while in operation. Trimmer should be held at a

comfortable position with the rear handle about hip height.

Cut tall grass from the top down. This will prevent grass from

wrapping around the shaft housing and string head which

could cause damage from overheating. If grass becomes

wrapped around the string head, STOP THE ENGINE,

disconnect the spark plug wire, and remove the grass.

WARNING:

Always hold the string trimmer away from the body

keeping clearance between the body and the product.

Any contact with the housing or string trimmer cutting

OPERATION

CUTTING TIPS

See Figures 9 - 11.

 Avoid hot surfaces by always keeping the tool away from

your body. (Proper operating position shown in figure 9.)

 Keep the trimmer tilted toward the area being cut; this is

the best cutting area.

 The curved shaft trimmer cuts when passing the unit from

right to left. The straight shaft trimmer cuts when passing

the unit from left to right. This will avoid throwing debris at

the operator. Avoid cutting in the dangerous area shown

in illustration.

 Use the tip of line to do the cutting; do not force string

head into uncut grass.

 Wire and picket fences cause extra line wear, even

breakage. Stone and brick walls, curbs, and wood may

wear line rapidly.

 Avoid trees and shrubs. Tree bark, wood moldings, siding,

and fence posts can easily be damaged by the line.

TO ADVANCE THE CUTTING LINE

Line advance is controlled by tapping the string head on

grass while running engine at full throttle.

 Run engine at full throttle.

 Tap the bump knob on ground to advance line. The line

advances each time the knob is tapped. Do not hold the

knob on the ground.

NOTE: The line trimming cut-off blade on the grass deflector

will cut the line to the correct length.

NOTE: If the line is worn too short you may not be able to

advance the line by tapping it on the ground. If so, stop the

engine and manually advance the line.

To advance the cutting line manually:

Stop the engine and disconnect the spark plug wire.

 Push the bump knob down while pulling on line(s) to

manually advance the line.

GRASS DEFLECTOR LINE TRIMMING CUT-OFF

BLADE

See Figure 12.

The trimmer is equipped with a line trimming cut-off blade

on the grass deflector. For best cutting, advance line until it

is trimmed to length by the cut-off blade. Advance the line

whenever you hear the engine running faster than normal,

or when trimming efficiency diminishes. This will maintain

best performance and keep the line long enough to advance

properly.

 Position camshaft by pulling the starter grip and rope just

until the deep hole in the camshaft gear is located at the

6 o’clock position as shown.

 Place the feeler gauge under each rocker arm and measure

the gap. The gap should be between .004 in. (0.10 mm)

and .006 in. (0.15 mm) for both rocker arms.

NOTE: Use a standard automotive feeler gauge. The

.004 in. (0.10 mm) feeler gauge should slide between

the rocker arm and valve stem with a slight amount of

resistance but without binding. The 0.006 in. (0.15 mm)

feeler gage should not slide between the rocker arms and

the cam lobes — it should be held tight.

 If the valve clearance is not between .004 in. (0.10 mm)

and .006 in. (0.15 mm), the clearance should be adjusted

as follows:

 Reinstall the air filter.

NOTE: Make sure the filter is seated properly inside the

cover. Installing the filter incorrectly will allow dirt to enter

the engine, causing rapid engine wear.

 Replace the air filter cover by placing the slots on the air

filter cover over the tabs on the housing, then push the

cover down until it latches securely in place.

FUEL CAP, TANK, AND LINES

toxique peut causer une perte de conscience et être mortel.

 Déblayer la zone de travail avant chaque utilisation. La

débarrasser de tous les objets tels que cailloux, verre brisé,

clous, fils métalliques, cordes, etc. risquant d’être projetés

ou de se prendre dans la ligne de coupe ou la lame.

 Toujours porter une protection oculaire avec écrans latéraux

certifiée conforme à la norme ANSI Z87.1 ainsi qu’un

protection auditive lors de l’utilisation de ce produit.Si

cette précaution n’est pas prise, des objets peuvent être

projetés dans les yeux et causer des lésions graves.

 Porter des pantalons longs, manches longues, des

chaussures de travail et des gants épais. Ne pas porter

de vêtements amples, bijoux, shorts, sandales et ne pas

travailler pieds nus. Ne porter aucun bijou.

 Le fait de porter des vêtements de protection lourds peut

augmenter la fatigue de l’utilisateur, ce qui pourrait entraîner

un coup de chaleur. Si le temps est chaud et humide,

effectuer les gros travaux le matin ou en fin d’après-midi,

alors qu’il fait plus frais.

 Ne jamais utiliser cet outil en le tenant du côté gauche.

 Attacher les cheveux longs pour les maintenir au-dessus

des épaules, afin qu’ils ne se prennent pas dans les pièces

en mouvement.

 Garder les badauds, enfants et visiteurs à une distance de 15

m (50 pi). Recommander aux personnes présente de porter

une protection oculaire. Si quelqu’un s’approche pendant

l’utilisation de l’outil, arrêter le moteur et l’accessoire de

coupe. Le risque de blessure est accru si on utilise un outil

à lames. En effet, les personnes se trouvant à proximité

risquent d’être heurtés par une lame en marche advenant

qu’elle ricoche, ou à la suite de toute autre réaction

inattendue de la scie.

 Ne pas utiliser cet outil en état de fatigue, si l’on est souffrant

ou contrarié, ou sous l’influence de l’alcool, de drogues

ou de médicaments.

 Ne pas travailler sous un éclairage insuffisant.

 Se tenir bien campé et en équilibre. Ne pas travailler hors

de portée. Le travail hors de portée risque de faire perdre

l’équilibre ou de causer un contact avec les pièces brûlantes.

 Ne pas utiliser sur une échelle, un toit, dans un arbre ou

sur toute surface instable. Une bonne tenue et un bon

équilibre permettent de mieux contrôler l’outil en cas de

situation imprévue.

 Garder toutes les parties du corps à l’écart des pièces en

doit jamais tourner au ralenti. La rotation au ralenti est

toutefois permise lors du réglage du carburateur.

 Il a été rapporté que, chez certaines personnes, les

vibrations produites par les outils à main motorisés peuvent

contribuer au développement d’une affection appelée

syndrome de Raynaud. Les symptômes peuvent inclure des

picotements, l’insensibilisation et le blanchissement des

doigts et sont habituellement provoqués par l’exposition

au froid. L’hérédité, l’exposition au froid et à l’humidité,

le régime alimentaire, la fumée et les habitudes de travail

sont tous des facteurs considérés comme contribuant au

développement de ces symptômes. Il n’existe actuellement

aucune preuve qu’un certain type de vibration ou le degré

d’exposition contribue réellement au développement de

cette affectation. Certaines mesures, susceptibles de réduire

les effets des vibrations, peuvent être prises par l’opérateur :

a) Garder le corps au chaud par temps froid. Pendant

l’utilisation, porter des gants afin de tenir les mains et

les poignets au chaud. Il a été établi que le froid est

l’une des principales causes du symptôme de Raynaud.

b) Après chaque période d’utilisation, faire des exercices

pour accroître la circulation.
