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.

 Never start or run the engine in a closed or poorly venti-

lated area; breathing exhaust fumes can kill.

 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.

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

Do not wear loose tting clothing, short pants, sandals,

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

 Heavy protective clothing may increase operator fa-

tigue, 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 tem-

peratures are cooler.

 Product users on United States Forest Service land,

and in some states, must comply with re prevention

regulations. This product is equipped with a spark arres-

tor; however, other user requirements may apply. Check

with your federal, state, or local authorities.

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

 Secure long hair above shoulder level to prevent en-

tanglement 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 be-

ing 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, or under

the inuence of alcohol, drugs, or medication.

 Do not operate in poor lighting.

 Keep rm footing and balance. Do not overreach. Over-

reaching can result in loss of balance or exposure to hot

surfaces.

 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 mufer 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.

 The cutting attachment should never rotate at idle dur-

ing 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 in-

clude tingling, numbness, and blanching of the ngers,

usually apparent upon exposure to cold. Hereditary

factors, exposure to cold and dampness, diet, smok-

ing, 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 condi-

tion, immediately discontinue use and see your physi-

cian about these symptoms.

 Mix and store fuel in a container approved for gasoline.

 Mix fuel outdoors where there are no sparks or ames.

Wipe up any fuel spillage. Move 30 ft. away from refu-

eling site before starting engine. Slowly remove the fuel

cap after stopping engine. Do not smoke when refuel-

ing.

 Stop the engine and allow to cool before refueling or

storing the unit.

 Allow the engine to cool; empty the fuel tank into a

container approved for fuel 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.

Operating the Trimmer

Operating the trimmer differs, depending on whether you are

using the curved shaft trimmer or the straight shaft trimmer.

WARNING:

Engine housing may 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

trimmers as shown in Figure 9 and 10 with all

body parts clear of engine housing. Extended

contact with the engine housing can result in

burns or other injuries.

Cutting Tips

See Figures 12 and 13.

1. Avoid hot surfaces by always keeping the tool away

from your body. (Proper operating position is shown in

Figures 9 and 10.)

2. Keep the trimmer tilted toward the area being cut; this

is the best cutting area.

3. 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 gures 12 and 13.

4. Use the tip of string to do the cutting; do not force

string head into uncut grass.

5. Wire and picket fences cause extra string wear, even

breakage. Stone and brick walls, curbs and wood may

wear string rapidly.

6. Avoid trees and shrubs. Tree bark, wood moldings, sid-

ing and fence posts can easily be damaged by the string.

Line advance is controlled by tapping the string head on

grass while running engine at full throttle.

 Run engine at full throttle.

 Tap the 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 deector

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 knob in while pulling on line(s) to manually
