5.Reduce the air motor regulator pressure and open the air motor valve.

6.Adjust air motor regulator until the pump starts.

7.Cycle the pump slowly until all air is pushed out and the pump and hoses are fully primed.

8.Release the gun/valve trigger and lock the trigger safety. The pump should stall against pressure.

To reduce the risk of fluid injection, do not use your hand or fingers to cover the bleed hole on the under- side of the bleed valve body (P) when priming the pump. Use the handle or a crescent wrench to open and close the bleed plug. Keep your hands away from the bleed hole.

9.If the pump fails to prime properly, open the pump bleed valve (P) slightly. Use the bleed hole, on the underside of the valve, as a priming valve until the fluid appears at the hole. Close the plug.

Always use lowest possible fluid pressure to bleed air out of pump.

FIG. 11

When changing fluid containers with the hose and gun/valve already primed, open the pump bleed

valve (P), to help prime the pump and vent air before it enters the hose. Close the valve when all air is eliminated.

CAUTION

Do not allow the pump to run dry. It will quickly accel- erate to a high speed, causing damage. If your pump is running too fast, stop it immediately and check the fluid supply. If the container is empty and air has been pumped into the lines, refill the container and prime the pump and the lines, or flush and leave it filled with a compatible solvent. Eliminate all air from the fluid system.

10.With the pump and lines primed, and with adequate air pressure and volume supplied, the pump will start and stop as you open and close the gun/valve. In a circulating system, the pump will speed up or slow down on demand, until the air supply is shut off.

11.Use the air motor regulator (see FIG. 10) to control the pump speed and the fluid pressure. Always use the lowest air pressure necessary to get the desired results. Higher pressures cause premature tip/noz- zle and pump wear.
