KNOW YOUR TRIMMER

READ THIS OPERATOR'SMANUAL AND SAFETY RULES BEFORE OPERATING YOUR UNIT. Compare the illustrations with your unit to familiarize yourself with the loca- tion of the various controls and adjustments. Save this manual for future refer- ence.

ON/STOP SWITCH

The STOP switch is used to stop engine. Press and hold switch to stop engine.

PRIMER BULB

The primer bulb removes air from the fuel lines and fills them with fuel. This

allows you to start the engine with few- er pulls on the starter rope. Activate

the primer bulb by pressing it and

BEFORE STARTING ENGINE WARNING:Be sure to read the fuel

information in the safety rules before you begin. If you do not understand the safety rules, do not attempt to fuel your unit. Call 1-800-235-5878.

FUELING ENGINE

This engine is certified to operate on unleaded gasoline. Before operation, gasoline must be mixed with a good quality 2-cycle air-cooled engine oil. We recommend Craftsman brand oil. Mix gasoline and oil at a ratio of 40:1 (A 40:1 ratio is obtained by mixing 3.2 ounces of oil with 1 gallon of unleaded

gasoline). DO NOT USE automotive oil or boat oil. These oils will cause

engine damage. When mixing fuel, follow instructions printed on container.

allowing it to return to its original form.

CHOKE

The choke helps to supply fuel to the carburetor during starting. This allows you to start a cold engine. Activate the choke by moving choke lever to the Full position. After the engine has started, move the choke to the Off position.

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.

IMPORTANT

Experience indicates that alcohol blended fuels (called gasohol or using ethanol or methanol) can attract mois- ture which leads to separation and formation of acids during storage. Acidic gas can damage the fuel sys- tem of an engine while in storage.

To avoid engine problems, empty the fuel system before storage for 30 days or longer. Drain the gas tank, start the engine and let it run until the fuel lines and carburetor are empty. Use fresh fuel next season.

NOTE: If engine dies with the choke lever at the Off Choke position, move the choke lever to Half Choke and pull the rope until engine runs.

STARTING A WARM ENGINE

???Move the choke lever to the Half Choke position.

???Squeeze and hold the throttle trigger. Keep throttle trigger fully squeezed until the engine runs smoothly.

???Pull starter rope sharply until engine runs, but no more than 5 pulls.

???Allow engine to run 15 seconds, then move the choke lever to Off Choke.

NOTE: If engine has not started, pull starter rope 5 more pulls. If engine still does not run, it is probably flooded.

DIFFICULT STARTING OR

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 how badly the unit is flooded.

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

OPERATING INSTRUCTIONS

OPERATING POSITION

To advance line, tap bottom of trimmer head on ground one time.

Llrnplei_e rg_hUs.linet t?? "_

H_??;gY _t_s __

Cut from your right to your left.

Bring the engine to cutting speed be- fore entering the material to be 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.

If the trimmer head does not turn when the engine is in operation, make sure the drive shaft housing is properly seated in engine shroud.

Always release the throttle trigger and allow the engine to return to idle speed when not cutting.

To stop engine:

???Release the throttle trigger.

???Push and hold down the on/stop switch until the engine has stopped completely.

TRIMMER LINE ADVANCE

The trimmer line will advance approxi- mately 2 in. (5 cm) each time the bot- tom 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 in. (5 cm) of line will be advanced with each tap.

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.

Ifthe line is worn down to 2 in. (5 cm) or less, more than one tap will be re- quired to obtain the most efficient line length.

WARNING;Use only .080" (2 mm) diameter line. Other sizes of line will

not advance properly and can cause serious injury. Do not use other materi- als 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

WARNING: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 seri- ous 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.

???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 dam-

age especially to delicate vegetation or trees with tender bark, shorten line

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

SCALPING - The scalping technique removes unwanted vegetation. Hold the bottom of the trimmer head about 3

in. (8 cm) above the ground and at an angle. Allow the tip of the line to strike the ground around trees, posts, monu- ments, etc. This technique increases line wear.

Scalping

EDGING - Your unit can be used for

edging sidewalks, patios, driveways, etc. While edging, allow the tip of the line to make contact. Do not force line. Take extra caution while edging as objects can be thrown by trimmer line.

CARBURETOR ADJUSTMENT WARNING:The trimmer head will be spinning during most of this procedure. Wear your protective equipment and observe all safety precautions. After making mixture adjustments, recheck idle speed.

Carburetor adjustment is critical and if done improperly can permanently

damage the engine as well as the car- buretor. If you require further assis- tance or are unsure about performing this procedure, call our customer as- sistance help line at 1-800-235-5878. Old fuel, a dirty air filter, a dirty fuel fil- ter, or flooding may give the impres- sion of an improperly adjusted carbu- retor. Check these conditions before adjusting the carburetor.

The carburetor has been carefully set at the factory. Adjustments may be necessary if you notice any of the fol- lowing conditions:

???Engine will not idle. See "Idle Speed" under adjusting procedure.

???Engine dies or hesitates instead of accelerating. See "Acceleration Check" under adjusting procedure.

???Loss of cutting power. See "Mixture Adjustment" under adjusting procedure.

There are two adjustment screws on the carburetor.

When making carburetor preset adjust- ments, do not force plastic limiter caps beyond stops or damage will occur.

If carburetor presets are not needed, proceed to "Adjusting Procedure, Idle Speed."

To adjust presets:

???Turn mixture screw counterclockwise until it stops.

???Turn the idle speed screw clockwise

until it stops. Now turn counterclock- wise 4-1/2 turns.

???Start motor, cut grass for 3 minutes, and proceed to the adjustment section. If engine does not start, refer to troubleshooting chart or call 1-800-235-5878.

???If engine performance is acceptable at the preset positions, no further adjustment is necessary.

ADJUSTING PROCEDURE

Idle Speed

Allow engine to idle. Adjust speed until engine runs without stalling.

???Turn clockwise to increase engine speed if engine stalls or dies.

???Turn counterclockwise to decrease

speed.

No further adjustments are necessary if performance is satisfactory.

Mixture Adjustment "H"

DO NOT operate engine at full throttle for prolonged periods while making ad- justments. Damage to the engine can occur. Extend line to the length allow by the line limiter and cut some grass. Based on performance while cutting, turn the mixture adjustment in

1/16-turn increments as follows:

Prepare unit for storage at end of sea- son or if it will not be used for 30 days or more.

WARNING:

???Allow engine to cool, and secure the unit before storing or transporting.

???Store unit and fuel in a well venti- lated area where fuel vapors cannot
