SAFETY NOTICE: Exposure to vibra- tions through prolonged use of gaso-

line powered hand tools could cause blood vessel or nerve damage in the

fingers, hands, and joints of people

prone to circulation disorders or ab- normal swellings. Prolonged use in

cold weather has been linked to blood vessel damage in otherwise healthy

people. If symptoms occur such as

numbness, pain, loss of strength, change in skin color or texture, or loss of feeling in the fingers, hands, or joints, discontinue the use of this tool

and seek medical attention. An anti- vibration system does not guarantee

the avoidance of these problems. Us- ers who operate power tools on a con- tinual and regular basis must monitor

closely their physical condition and the condition of this tool.

SPECIAL NOTICE: This unit is

equipped with a temperature limiting

muffler and spark arresting screen

which meets the requirements of Cali- fornia Codes 4442 and 4443. All U.S. forest land and the states of California,

Idaho, Maine, Minnesota, New Jersey, Oregon, and Washington require by law that many internal combustion en-

gines be equipped with a spark arrest-

ing screen. If you operate in a locale

where such regulations exist, you are

legally responsible for maintaining the

operating condition of these parts.

obtained by mixing 3.2 ounces of oil with 1 gallon of unleaded gasoline.

Included with this trimmer is a 3.2

ounce container of oil. Pour the entire contents of this container into 1 gallon

of gasoline to achieve the proper fuel

mixture. DO NOT USE automotive oil or boat oil. These oils will cause engine

damage, When mixing fuel, follow

instructions printed on container,

Once oil is added to gasoline, shake container momentarily to assure that the fuel is thoroughly mixed. Always read and follow the safety rules relating to fuel before fueling your unit.

STARTING A FLOODED ENGINE

Flooded engines can be started by

placing the choke lever in the OFF CHOKE position; then, pull the rope to clear the engine of excess fuel. This could require pulling the starter handle many times depending on hew badly

the unit is flooded,

If the unit still doesn't start, refer to TROUBLESHOOTING TABLE or call

1-800-235-5878. OPERATING INSTRUCTIONS

It is recommended that the engine

not be operated for longer than 1 minute at full throttle.

OPERATING POSITION

ALWAYS WEAR:

Eye Protection

Long

Heavy Shoe_

Cut fi'om your right to your left.

To stop engine:

• Release the throttle trigger.

• Push and release the engine ON/ STOP switch.

TRIMMER LINE ADVANCE The trimmer line will advance approxi-

mately 2 inches (5 cm) each time the

bottom of the trimmer head is tapped on the ground with the engine running at full throttle.

The most efficient line length is the

maximum length allowed by the line

limiter. Always keep the shield in place when

the tool is being operated. To advance line:

• Operate the engine at full throttle,

• Hold the trimmer head parallel to and above the grassy area,

• Tap the bottom of the trimmer head lightly on the ground one time, Ap-

proximately 2 inches (5 cm) of line will be advanced with each tap,

To advance line, tap bottom of trimmer

head on ground one time.

dl_ WARNING: Always wear eye

protection, Never lean over the trim-

mer head, Rocks or debris can rico- chet or be thrown into eyes and face

and cause blindness or other serious

injury.

When operating unit, stand as shown and check for the following:

• Wear eye protection and heavy clothing,

• Hold trigger handle with right hand and assist handle with left hand.

• Keep unit below waist level.

• Cut only from your right to your left to ensure debris is thrown away from

you. Without bending over, keep line

near and parallel to the ground and not crowded into material being cut.

Do not run the engine at a higher

speed than necessary. The cutting

line will cut efficiently when the engine is run at less than full throttle. At lower

speeds, there is less engine noise and vibration. The cutting line will last

longer and will be less likely to "weld"

onto the spool. Always release the throttle trigger and

allow the engine to return to idle speed when not cutting.

Always tap the trimmer head on a grassy area. Tapping on surfaces such as concrete or asphalt can cause ex-

cessive wear to the trimmer head,

If the line is worn down to 2 inches (5

cm) or less, more than one tap will be

required to obtain the most efficient line length.

_WARNING: Use only 0,065 inch

(1,65 mm) diameter line. Other sizes

and shapes of line will not advance

properly and will result in improper

cutting head function or can cause se-

rious injury. Do not use other materials

such as wire, string, rope, etc. Wire can break off during cutting and be-

come a dangerous missile that can cause serious injury.

CUTTING METHODS

_LWARNING: Use minimum speed and do not crowd the line when

cutting around hard objects (rock, gravel, fence posts, etc.), which can

damage the trimmer head, become entangled in the line, or be thrown causing a serious hazard.

• The tip of the line does the cutting.

You will achieve the best perform-

ance and minimum line wear by not crowding the line into the cutting area. The right and wrong ways are

shown below,

Tip of the Line I Line Crowded Into

Does Tl_eCutling Work Area

Right -':_&_ Wro -"

• The line will easily remove grass and weeds from around walls,

fences, trees and flower beds, but it

also can cut the tender bark of trees or shrubs and scar fences. To help

avoid damage especially to delicate vegetation or trees with tender bark,

shorten line to 4-5 inches (10-13 cm) and use at less than full throttle.

• For trimming or scalping, use less

than full throttle to increase line life

and decrease head wear, especially:

• During light duty cutting.

• Near objects around which the line

can wrap such as small posts,

trees or fence wire.

• For mowing or sweeping, use full

throttle for a good clean job.

TRIMMING - Hold the bottom of the trimmer head about 3 inches (8 cm)

above the ground and at an angle. Al-

low only the tip of the line to make contact. Do not force trimmer line into work area.

Trimming

SCALPING - The scalping technique

removes unwanted vegetationdown to the ground, Hold the bottom of the trimmer head about 3 inches (8 cm) above the ground and at an angle• Al-

low the tip of the line to strike the ground around trees, posts, monu-

ments, etc. This technique increases

line wear.

Scalping

• )

MOWING - Your trimmer is ideal for

mowing in places conventional lawn

mowers cannot reach. In the mowing

position, keep the line parallel to the ground. Avoid pressing the head into the ground as this can scalp the ground and damage the tool.

SWEEPING - The fanning action of the rotating line can be used for a quick and easy clean up. Keep the

line parallel to and above the sudaces

being swept and move the tool from

side to side.
