Know Your Controls Know Your Controls The ON/OFF power switch controls the main power to your sprayer. The power button is illuminated when ON. The Pressure Control knob increases or decreases the pressure and flow of the paint. The Prime/Spray Valve directs the fluid to either the Drain Tube or the hose and gun. It is used to prime the sprayer, which means to evacuate the air out of the pump, hose, and gun. Your gun will not spray if there is air in the system.
Grounding Instructions Grounding Instructions (Oil-Based or Flammable Materials) Fluid hoses: Use only electrically conductive hoses with a maximum of 300 ft. (91 m) combined hose length to ensure grounding continuity. The equipment must be grounded to reduce the risk of static sparking. A static spark can cause fumes to ignite or explode. A good ground provides an escape wire for the electric current. Spray gun: Grounded through connection to a properly grounded fluid hose and pump.
Grounding Instructions To maintain ground continuity when sprayer is flushed or pressure is relieved: hold metal part of spray gun firmly to the side of a grounded metal pail then trigger the gun.
Setup Setup Assemble Your Sprayer 1. 2. Connect airless hose to airless hose connection (P) on sprayer. Use wrench to tighten securely. Connect the other end of the hose to the gun. Use two wrenches to tighten securely to gun (see image below). NOTE: It is important to use two wrenches when connecting the hose to the gun, both for ease of installation and to ensure a tight connection. If hose is already connected, make sure connections are tight.
