How to Flush

WARNING

SKIN INJECTION HAZARD

Follow the Pressure Relief Procedure Warning on page 10. Remove the spray tip before flushing.

1.Engage the gun safety latch. Remove the spray tip from the gun.

2.Pour enough clean, compatible solvent to fill the pump and hoses into a large, grounded metal pail.

3.Place the suction tube into the pail or tilt the sprayer back (it will support itself) and place the pail under the pump. Then tilt the sprayer forward to lower the pump into the pail.

4.Turn the pressure control knob counterclockwise 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 further will remove it. Tighten the knob locknut to set. See Fig 5.

5.Open the bypass valve. The valve lever will be parallel to the body of the valve. See Fig 5.

6.Attach fuel hose from tank to engine.

7.Close the choke by moving the choke lever. See Fig 5.

CAUTION

The bypass valve must be opened when starting the sprayer to prevent damaging the starter.
