NOTE: Do not install the spray tip yet!
2.Open the
3.Hold a metal part of the spray gun firmly to the side of a grounded metal pail and trigger the gun.
4.Slowly open the air regulator until the pump starts.
5.Allow the pump to cycle slowly until all the air is pushed out of the fluid lines.
6.Release the gun trigger and lock the trigger safety; the pump will stall against the pressure.
7.With the pump and lines primed, and with ade- quate air pressure and volume supplied, the pump will start and stop as the spray gun is triggered and released.
WARNING
To reduce the risk of serious injury whenever you are instructed to relieve pressure, always follow the Pressure Relief Procedure on page 14.
8.Relieve the pressure, then install the spray tip in the gun.
9.Use the air regulator to control the pump speed and fluid pressure. 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.
CAUTION
Do not allow the pump to run dry. It will quickly accelerate 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 con- tainer and prime the pump and the lines, or flush and leave it filled with a compatible solvent. Eliminate all air from the fluid system.
