Step 4. Start the Engine to Power the Pump
1. Make sure a water supply is connected and primed.
Note: Running the pump dry will cause damage and void the warranty.
2. To prevent accidental spraying, engage the safety latch on the spray gun trigger by rotating it to the
locked position.
3. Follow these instructions for starting the engine:
a) To start a cold engine, move the choke lever to the close position. To restart a warm engine,
leave the choke lever in the open position. The choke lever opens and closes the choke valve
in the carburetor. The close position enriches the fuel mixture for starting a cold engine. The
open position provides the correct fuel mixture for operation after starting, and for restarting a
warm engine.
b) Move the throttle lever away from the SLOW position, about 1/3 of the way toward the FAST
position. The throttle controls the engine speed. Moving the throttle lever in one direction or
the other makes the engine run faster or slower.
