C. STARTING INSTRUCTIONS

1. HOW FUEL INJECTION STARTING TM WORKS

FUEL INJECTION STARTINGTMprovides a

quick, start feature by. injecting a precise

amount of fuel .directly into the. carburetor

manifold which provides a rich fuel mix for the

first few seconds of operation.

INJECTOR BuI-r ON

CARBURETOR

FUEL INJECTIONSTARTING DEVICE (PATENT PENDING)

Figure 6

DRAIN

- . • Each-time the injector button is pressed and

-.+.:_- ---released, fuel is forced'from'the fuel tank to '- the accumulator c:hamber.

• The accumulator chamber provides a sec- ondary fuel supply until the carburetor can obtain fuel through the primary line

• When the accumulator chamber isfull, fuel is injected into the carburetor manifold to

provide a rich mixture for starting.

Excess fuel escapes through a drain to

prevent the engine from flooding if the

injector button is pressed too many times. As a result, a few drops of fuel may appear on the ground during the starting procedure.

The number of injections required will depend on temperature conditions and the

time elapsed since the engine was last started.

2. STARTING PROCEDURE

3. IMPORTANT POINTS TO REMEMBER

a. Extenda minimumof4inchesoflinefromthe

cutting head to providethe correctload on the engine.

b. Stand in the operating position, and place

the cutting head on the ground. Figure 9. This insures that fuel will flow into the in-

jector pump.

c. Move the ignition switch to the "ON" posi-

tion. Figure 7.

d. Grip the rear handle with your right hand,

squeezing and keeping the throttle trigger

fully depressed until the engine runs

smoothly.

e. Press the injector button down fully allow-

ing the button to return completely after each pressing. Follow conditions and injec-

tions listed.

Conditions

I First Starting Out-of-Box [ - [ Above 30°F Temperature_

-- First starting/engine cold

-- Restarting/engine hot

{Below 30°F Temperature ]

-- (See "Cold Weather Starting", this page.)

f. Continue pressing and releasing the injector but-

ton untilfuel drips out of the bottom of the unit. [CAUTION: ] If more than a drop ortwo of fuel

spills onthe ground moveunit away toanother area for starting to avoid creating a fire hazard.

g. Pull starter rope quickly and sharply until

engine starts.

NOTE: If engine attempts to start but dies

or does not start after 5 (five) pulls, press

injector one more time and pull starter

rope again.

h. The engine will run roughly when first

started. It is important to keep the throttle trigger fully depressed until the engine runs smoothly (10 seconds or less)

i. If theengine starts but the cutting head does

not tum with the throttle trigger depressed, make sure the drive shaft housing is properly seated in the engine shroud. See "Ddve Shaft Housing",page 5.

Required Injections

3-4

0-1

a. If the engine starts to die immediately after

starting, keep throttle trigger depressed and press injector button once with fore- finger to give unit additional fuel.

b. If the engine is stopped momentarily (less

than 5 minutes), it probably will not require an injection.

c. If unit runs out of fuel or is drained for stor-

age "First Starting" procedure may be re- quired because the system will be dry.

d. After starting and engine runs smoothly,

keep unit running at half speed until engine is warmed up to proper idle.

e Usinggasoline orfuelmix over2 months old

will cause the engine to bedifficult or impos-

sible to start!

4. COLD WEATHER STARTING

(Below 30 ° F)

a. Follow "Starting Procedure" through step

"d", then as below.

b. Press injector button down fully six (6}

times allowing the button to return com- pletely after each pressing.

c. Pull starter rope quickly and sharply until

unit starts. Keep trigger fully depressed.

d. If unit does not start in four pulls or attempts

to start but dies, press injector button an

additional four times.

e. Continue pulling starter rope four pulls.

If unit fails to start, repeat step d., above.

f. It is important not to release trigger until

unit runs smoothly.

g. Once unit has started, immediately press

injector button two additional times to keep unit running until it warms up.

h. in extremely cold weather, it will be very

difficult to flood the unit, so if the unit

doesn't start-quickly, do not hesitate to

press injector button for additional fuel.

i. For starting warm engine in cold tempera-

tures, press injector button once before

starting.

OPERATING INSTRUCTIONS

For maximum performance and efficiency:

1. Always accelerate the engine to the desired speed before cutting.

2, Never operate the engine at a higher speed

than necessary.

3. Always release the trigger and allow the en-

gine to return to idle speed when not cutting.

ENGINE ADJUSTMENTS

1. CARBURETOR ADJUSTMENTS

The carburetorhasbeen carefully adjusted atthe factory.

Dueto changesin altitude and operating conditions, your carburetor may require adjusting. To make the adjust- ment follow the procedure below very carefully:

a. PREPARATION

1.) Use fresh fuel mix with proper gasoline/ oil ratio. See "Fuel Mixture", page 7.

2.)

Make sure the cutting line extends at least

4 inches toprovide correct load on engine.

3.)

Remove air filter ( Figure 10) and place under spark plug wire for safe keeping_

4.)

Turn both tow speed and high speed mixture screws clockwise _ untilfullyclosed, but do not overtighten. Figure 10.Unscrew beth

mixture screws one full turn counterclockwise

IDLE SPEED ADJUSTMENT 1 .,)Turn Idle Speed Screw clockwise

until it stops. Do not overtighten. Open screw one full turn counterclockwise.

2.) Start the engine and cut grass for 3 min- utes to warm up engine.

3.) Allow engine to idle.

4. ) AdjustIdleSpeed Screw untilengine continues

to run withoutstalling and without the cutting

head turning.

Turn screw clockwise _ to increase

Turn screw counterclockwise -_k'.,_to slow

l CAUTION: JHigh and low speed mixture settings

are highly critical adjustments. If setincorrectly per- manent damage will occur to the engine, Both the

low speed mix and the high speed mix screws

should be in the range of 3/4 to 1-1/4turns open.

- engine speed if engine Stalls; engine down if cutting head

continues toturn.

4. Make sure the cutting head stops turning

when the throttle trigger is released and the engine runs at idle speed, For correction,

refer to "Carburetor Adjustments," below_

5. Stop engine by moving the ignition switch to

the "OFF" position (Figure 8).

C. LOW SPEED MIXTURE ADJUSTMENT

1.) Allow engine to =die.

2.) Turn Low Speed Mixture Screw clock- wise _ slowly. Note the position at which the engine speed is increased.

3.) Turn the screw slowly countercfockwise. JP.,_. Note the position at which the speed is reduced.

4.) Set the screw mid-way between these two extreme :positions.

d. IDLE SPEED ADJUSTMENT

1.) Allow engine to idle.

2.) Adjust the Idle Speed Screw until the engine idles as fast as possible without

the cutting head or blade turning

E-CAUTION:] Do not operate engine at full throttle

for prolonged periods while making high speed adjustments as damage to the engine can occur.

e. HIGH SPEED MIXTURE ADJUSTMENT

1 ) Support the shaft so that the cutting head

is off the ground and will not contact anv

object.
