Shutdown and Care

Operation

Slowly open the pump air regulator (10b) until the pump starts. Run the pump slowly until fluid comes from the drain valve (6). Close the drain valve and continue to run the pump until all the air is pushed out of the fluid lines. Release the gun trigger and lock the safety latch; the pump will stall against the pressure.

With the pump and lines primed, and with adequate air pressure and volume supplied, the pump will start and stop as the spray gun is triggered and released.

Relieve the pressure, then install the spray tip in the gun.

Never allow the pump to run dry of the fluid being pumped. A dry pump will quickly accelerate to a high speed, possibly damaging itself. If your pump acceler- ates quickly, or is running too fast, stop it immediately and check the fluid supply. If the supply container is empty and air has been pumped into the lines, refill the supply container and prime the pump and lines with fluid, being sure to eliminate all air from the fluid sys- tem, or flush the pump as described in Shutdown and Care, at right.

Use the pump air regulator (10b) to control the pump speed and fluid pressure. On models with a fluid pressure regulator (29), use it for more precise control of pressure at the gun. Always use the lowest pressure necessary to achieve the desired results. Higher pressures waste fluid and cause premature wear of the pump packings and spray tip.

Keep the packing nut/wet-cup filled with Graco Throat Seal Liquid (TSL) to help prolong the packing life. Check the tightness of the packing nut weekly. The packing nut should be tight enough to prevent leakage

±no tighter. Always relieve the pressure before adjusting the packing nut.

WARNING

To reduce the risk of serious injury whenever you are instructed to relieve pressure, always follow the Pressure Relief Procedure on page 8.

Relieve the pressure whenever you shut off the pump. Stop the pump at the bottom of its stroke to keep fluid from drying on the exposed displacement rod and damaging the throat packings.

Always flush the pump with a compatible solvent before the fluid can dry on the displacement rod, and at the end of each day. Relieve pressure after flushing.
