BOX 1441 MINNEAPOLIS, MN 55440–1441 MOVING PARTS HAZARD SAFETY WARNINGS HIGH PRESSURE FLUID CAN CAUSE SERIOUS INJURY. FOR PROFESSIONAL USE ONLY. OBSERVE ALL WARNINGS. Read And Understand All Instruction Manuals Before Operating Equipment. The air motor piston (located behind the air motor shield) also moveswhen air is supplied to the motor. NEVER operate the pump with the air motor shield removed. Before servicing the pump, follow the Pressure Relief Procedure below to prevent the pump from starting accidentally. TipGuard (only on spray guns) ALWAYS have the tip guard in place on the spray gun while spraying. Thetip guard alerts you to the fluid injection hazard and helps reduce, but does not prevent, the risk of accidentally placing your fingers or any partof your body close to the spray tip. Spray Tip/Nozzle Safety Use extreme caution when cleaning or changing spray tips/nozzles. If the spray tip/nozzle clogs while spraying/dispensing, engage the gun/valvesafety latch immediately. ALWAYS follow the Pressure Relief Procedure and then remove the spray tip/nozzle to clean it. NEVER wipe off build–up around the spray tip/nozzle until pressure isfully relieved and the gun/valve safety latch is engaged. Pressure Relief Procedure To reduce the risk of serious bodily injury, including fluid injection, splashing in the eyes or on the skin, or injury from moving parts, always follow this procedure whenever you shut of f the pump, when checking or servicing any part of the spray/dispensing system, when installing, cleaning or changing spray tips/nozzles, andwhenever you stop spraying/dispensing. 1. Engage the gun/valve safety latch. 2. Shut off the air to the pump. 3. Close the bleed–type master air valve (required in your system). 4. Disengage the safety latch. 5. Hold a metal part of the gun/valve firmly to the side of agrounded metal pail, and trigger the gun/valve to relieve pressure. 6. Engage the gun/valve safety latch. 7. Open the drain valve and/or the pump bleeder valve (requiredin your system), having a container ready to catch the drainage. 8. Leave the drain valve open until you are ready to spray/dispense again. If you suspect that the spray tip/nozzle or hose is completely clogged, or that pressure has not been fully relieved after followingthe steps above, VERY SLOWLY loosen the tip guard retaining nut, nozzle, or hose end coupling and relieve pressure gradually, then loosen completely. Now clear the tip/nozzle or hose. KEEP HANDS AND FINGERS AWAY FROM THE PRIMING PISTON DURING OPERATION AND WHENEVER THE PUMP IS CHARGED WITH AIR to reduce the risk of injury! On the pump downstroke thepriming piston extends beyond the intake cylinder to pull the material intothe pump. The priming piston works under extreme force. During operation and whenever the pump is charged with air, the priming piston canseverely injure or amputate a hand or finger, or break a tool, caught between it and the intake cylinder. Always follow the Pressure Relief Procedure, below, before checking, clearing, cleaning, flushing or servicing any part of the pump. FLUID INJECTION HAZARD General Safety This equipment generates very high fluid pressure. Spray from the gun/ valve, leaks or ruptured components can inject fluid through your skinand into your body and cause extremely serious bodily injury, includingthe need for amputation. Also, fluid injected or splashed into the eyes or on the skin can cause serious damage. NEVER point the gun/valve at anyone or at any part of the body. NEVER put hand or fingers over the spray tip/nozzle, or over the bleeder valvehole. ALWAYS follow the Pressure Relief Procedure, right, before cleaning or...
