The primer system only pushes fuel 

through the carburetor. Repeatedly 

pressing the primer bulb will not flood 

the engine with fuel.

CAUTION!
Do not pull the recoil starter to the 

end of the rope travel. Pulling the 

recoil starter to the end of the rope 

travel can damage the starter.

Place suction intake and strainer 

1. 

in the water to be pumped prior to 

starting engine. 
Set throttle control lever to the half 

2. 

open position. See Figure 3.

Press the primer bulb until fuel can 

3. 

be seen flowing in the transparent 

return tube. See Figure 4.

WARNING!
Do not run engine in an 

enclosed area. Exhaust gas con-

tains carbon monoxide, an odorless 

and deadly poison.

If the engine fails to start after several 

attempts with the choke in the closed 

position, the engine may be flooded 

with fuel. If flooding is suspected, move 

the choke lever to the open position 

and repeatedly pull the recoil starter 

to remove excess fuel and start the 

engine. If the engine still fails to start, 

refer to the troubleshooting section of 

this manual.

Set the choke lever to the CLOSED 

4. 

position if the engine is cold.
While holding the pump handle 

5. 

firmly with your left hand, use your 

other hand to slowly pull the recoil 

starter handle until resistance is 

felt, then pull quickly to start the 

engine. See Figure 6

When the engine starts, slowly 

6. 

move the choke lever to the 

"OPEN" position. See Figure 7. (If 

the engine stops after the initial 

start, close the choke and restart.)

Repeat the appropriate procedures for starting a warm or cold engine.

1. 

If the engine fails to start, follow the procedures in “Starting a Flooded 

2. 

Engine”.

Do not start or run the pump without 

priming the pump with water. Serious 

damage to the pump seals will occur 

when the pump is run dry.

When the engine starts, gradu-

7. 

ally move the throttle control 

lever back to the idle position 

(counterclockwise).

After the engine starts, allow the 

8. 

engine to warm up at idle 2 or 3 

minutes before operating the unit.
Place throttle lever (D) in half throt-

9. 

tle position until pump begins to 

pump water. Then move lever to full 

throttle.

Open the choke, put the throttle trigger in the full throttle position, then clear excess fuel from the combustion chamber by 

1. 

cranking the engine several times.
If the engine still fails to start or fire, refer to the troubleshooting flow chart at the end of this manual.
