How to Flush

------------WARNING----------~

Follow the Pressure Relief Procedure Warning on page 2 or B. Then remove the spray tip before flushing.

1.Be sure the gun safety latch is engaged, and there is no spray tip in the gun.

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

3.Place the accessory 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 cause it to fall off. Tighten the knob locknut to set. See Fig 5.

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

5.Storage.

Water-base paint: flush with water, then mineral spirits and leave the pump, hose and gun filled with mineral spirits to prevent corrosion. Follow the

Pressure Relief Procedure Warning on page 2 or

B.

Oil-base paint: flush with mineral spirits. Follow the Pressure Relief Procedure Warning on page 2 or B.

6.Startup after storage.

Before using water-base paint, flush out mineral spirits with soapy water and then a clean water flush.

When using oil-base paint, flush out the mineral spirits with the fluid to be sprayed and the sprayer is ready to use.

6.Open the fuel shutoff valve by screwing it out as far as it will go. See Fig 5.

7.Turn the choke off by turning the lever so it is horizontal. See Fig 6.

B.Brace one foot against the frame and gently pull the starter rope out until you feel it engage, then con- tinue pulling all the way out and let it recoil slowly into the starter. Then, holding the starter rope firm- ly, 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.

---------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.

9.After the engine is warm, gradually open the choke lever and close the bypass valve. See Fig 5 and 6.
