Grounding Grounding grounding continuity. The equipment must be grounded to reduce the risk of static sparking and electric shock. An electric or static spark can cause fumes to ignite or explode. An improper ground can cause electric shock. A good ground provides an escape wire for the electric current.
Pressure Relief Procedure Pressure Relief Procedure Engage the trigger lock. Follow the Pressure Relief Procedure whenever you see this symbol. This equipment stays pressurized until ti25196a pressure is manually relieved. To help prevent serious injury from pressurized Turn pressure control to the lowest fluid, such as skin injection, splashed fluid setting.

Setup 11. Place fluid intake with drain tube in a grounded metal pail partially filled with flushing fluid. See Grounding, page 8. ti24640a NOTE: New sprayers are shipped with storage fluid that must be flushed out with mineral spirits prior to using the sprayer. ti25291a Check flushing fluid for compatibility with material that is to be sprayed.
Startup/Prime Startup/Prime Increase pressure 1/2 turn to start motor. Allow paint to circulate through sprayer until paint flows out the drain tube. Perform Pressure Relief Procedure, page 9. Turn pressure control to lowest pressure. 15 s ti25292a ti25287a Turn prime valve horizontal. Disengage the trigger lock.

Startup/Prime Hold gun against a grounded metal waste pail. Trigger gun until paint appears. High-pressure spray is able to inject toxins into the body and cause serious bodily injury. Do not stop leaks with hand or rag. Inspect for leaks. If leaks occur, perform Pressure Relief Procedure, page 9, then tighten all fittings and repeat Startup procedure.
Operation Operation Spray Tip Installation 3. Screw assembly onto gun. Tighten. 1. Perform Pressure Relief Procedure, page 9. 2. Use spray tip (A) to insert ™ OneSeal (B) into tip guard (C). ti24652a Spray Spray test pattern. Adjust pressure to eliminate heavy edges.
Operation Clear Tip Clog Engage the trigger lock. Return Spray Tip to original position. Disengage the trigger lock and continue spraying. Release the trigger. Engage the trigger lock. Rotate Spray Tip. Disengage the trigger lock. Trigger gun at waste area to clear clog.
Operation Cleanup Perform Pressure Relief Procedure, page 9. Remove tip guard and Spray Tip. For additional information, see separate gun manual. ti24709a Place fluid intake in a flushing fluid. Use water for water base paint and mineral spirits for oil-based paint. Place drain tube in a waste pail.
