Operation

Starting and Adjusting the Pump

See Fig. 2 on page 7. Be sure the air regulator (E) and bleed-type master air valve (D) are closed. Do not install the spray tip yet!

Connect a suction hose (N) to the pump’s fluid inlet. Hold a metal part of the spray gun (M) firmly to the side of a grounded metal pail and hold the trigger open. Then open the pump’s bleed-type master air valve (D). Now slowly open the air regulator until the pump starts, about 40 psi (0.3 MPa, 3 bar).

Cycle the pump slowly until all the air is pushed out and the pump and hoses are fully primed. Release the spray gun trigger and lock the trigger safety. The pump should stall against pressure when the trigger is re- leased.

WARNING

To reduce the risk of serious injury whenever you are instructed to relieve pressure, always follow the Pressure Relief Procedure on page 9.

Relieve the pressure. Install the spray tip as explained in your separate gun manual.

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 opened and closed. In a circu- lating system, the pump will run continuously and will speed up or slow down as supply demands until the air supply is shut off.

Use an adequately sized air regulator (E) to control the pump speed and the fluid pressure. Always use the lowest air pressure necessary to get the desired re- sults. Higher pressures waste fluid and cause prema- ture wear of the pump packings and spray tip.

WARNING

COMPONENT RUPTURE HAZARD To reduce the risk of overpressurizing

your system, which could cause compo- nent rupture and serious injury, never

exceed the Maximum Air Input Pressure marked on the pump. Refer to the Technical Data on page 20.

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.

A pump runaway valve (B), which shuts off the air supply to the pump if the pump accelerates beyond the pre-set speed, is available. See Fig. 2 on page
