1.Prepare the Fluid

a.Prepare the fluid according to the fluid manufacturer'srecommendations.

b.Place the pump or accessory suction tube into the fluid container.

2.Starting the Sprayer

a.Open the bypass valve to make startup easier. In the open position, the valve lever is parallel to the body of the valve. Refer to Fig 8. Close the filter drain valve.

b.Turn the pressure control knob counterclock- wise until all spring tension is relieved. You will be able to feel it. The sprayer is now set at the lowest pressure setting. Turning the knob fur- ther will cause it to fall off.

c.Open the fuel shutoff valve to a vertical posi- tion. See Fig 8.

d.If the engine is cold, close the choke by turning the lever in the direction of the arrow. See Fig 9.

e.Brace one foot against the frame and gently pull the starter rope until you feel it engage, then continue pulling all the way out and let it recoil slowly into the starter. Then, holding the starter rope firmly, rapidly pull the rope to start the engine. If it does not start after one or two attempts, open the choke a little more. If the engine floods, open the choke all the way and continue pulling the rope.

r--~----WARNING ------- .

Always hold the starter rope firmly while pulling or recoiling it to reduce the chance of being hit and injured by the rope or of jamming and damaging the starter assembly.
