				EQUIPMENT MISUSE HAZARD   
					General Safety   
					System Pressure   
					Any misuse of the spray/dispensing equipment or accessories, such as   
					The 10:1 Bulldog Pump develops 1000 psi (70 bar) MAXIMUM WORK   
					- 
					- 
					overpressurizing, modifying parts, using incompatible chemicals and flu   
					ids, or using worn or damaged parts, can cause them to rupture and result   
					in fluid injection, splashing in the eyes or on the skin, or other serious bod   
					ily injury, or fire, explosion or property damage.   
					- 
					ING PRESSURE at 100 psi (7 bar) air pressure. The 20:1 King Pump de   
					velops 1800 psi (124 bar) MAXIMUM WORKING PRESSURE at 90 psi   
					(6 bar) air pressure. Never exceed these pressures.   
					- 
					Be sure that all spray/dispensing equipment and accessories are rated to   
					withstand the maximum working pressure of the pump. DO NOT exceed   
					the maximum working pressure of any component or accessory used in   
					the system.   
					NEVER alter or modify any part of this equipment; doing so could cause it   
					to malfunction.   
					Fluid Compatibility   
					BE SURE that all fluids and solvents used are chemically compatible with   
					the wetted parts shown in the TECHNICAL DATA on the back cover Al-   
					ways read the manufacturer   
					this pump.   
					CHECK all spray/dispensing equipment regularly and repair or replace   
					worn or damaged parts immediately   
					. 
					. 
					Always wear protective eyewear, gloves, clothing and respirator as rec   
					ommended by the fluid and solvent manufacturer   
					- 
					’s literature before using fluid or solvent in   
					. 
					HOSE SAFETY   
					High pressure fluid in the hoses can be very dangerous. If the hose devel   
					ops a leak, split or rupture due to any kind of wear, damage or misuse, the   
					high pressure spray emitted from it can cause a fluid injection injury or   
					other serious bodily injury or property damage.   
					- 
					HANDLE AND ROUTE HOSES CAREFULLY. Do not pull on hoses to   
					move equipment. Do not use fluids which are not compatible with the in   
					- 
					- 
					ner tube and cover of the hose. DO NOT expose Graco hoses to tem   
					peratures above 82_   
					C 
					(180_ F) or below –40_   
					C 
					(–40_ F).   
					ALL FLUID HOSES USED WITH A FLEXING MOTION MUST HAVE   
					SPRING GUARDS ON BOTH ENDS! The spring guards help protect   
					the hose from kinks or bends at or close to the coupling which can result   
					in hose rupture.   
					Hose Grounding Continuity   
					Proper hose grounding continuity is essential to maintaining a grounded   
					spray system. Check the electrical resistance of your air and fluid hoses   
					at least once a week. If your hose does not have a tag on it which speci   
					- 
					TIGHTEN all fluid connections securely before each use. High pressure   
					fluid can dislodge a loose coupling or allow high pressure spray to be   
					emitted from the coupling.   
					fies the maximum electrical resistance, contact the hose supplier or   
					manufacturer for the maximum resistance limits. Use a resistance meter   
					in the appropriate range for your hose to check the resistance. If the resis   
					tance exceeds the recommended limits, replace it immediately. An un   
					- 
					- 
					NEVER use a damaged hose. Before each use, check the entire hose for   
					cuts, leaks, abrasion, bulging cover, or damage or movement of the hose   
					couplings. If any of these conditions exist, replace the hose immediately   
					grounded or poorly grounded hose can make your system hazardous.   
					Also, read FIRE OR EXPLOSION HAZARD, below   
					. 
					. 
					DO NOT try to recouple high pressure hose or mend it with tape or any   
					other device. A repaired hose cannot safely contain the high pressure   
					fluid.   
					FIRE OR EXPLOSION HAZARD   
					Static electricity is created by the flow of fluid through the pump and hose.   
					If every part of the spray/dispensing equipment is not properly grounded,   
					sparking may occur, and the system may become hazardous. Sparking   
					may also occur when plugging in or unplugging a power supply cord.   
					Sparks can ignite fumes from solvents and the fluid being sprayed, dust   
					Grounding   
					To reduce the risk of static sparking, ground the pump, object being   
					sprayed, and all other spray/dispensing equipment used or located in the   
					spray/dispensing area. CHECK your local electrical code for detailed   
					grounding instructions for your area and type of equipment. BE SURE to   
					ground all of this spray/dispensing equipment:   
					particles and other flammable substances, whether you are spraying/dis   
					pensing indoors or outdoors, and can cause a fire or explosion and seri   
					ous bodily injury and property damage. Do not plug in or unplug any   
					power supply cords in the spray/dispensing area when there is any

					tem for proper grounding. Do not use the system again until the problem   
					has been identified and corrected.   
					5. Spray gun/dispensing valve: grounding is obtained through con-   
					nection to a properly grounded fluid hose and pump.   
					To ground the pump:   
					6. Fluid supply container: according to your local code.   
					7. Object being sprayed: according to your local code.   
					To ground the pump, loosen the grounding lug locknut (W) and   
					washer (X). Insert one end of a 1.5 mm@ (12 ga) minimum ground   
					wire (Y) into the slot in lug (Z) and tighten the locknut securely. See   
					Fig 1. Connect the other end of the wire to a true earth ground. See   
					ACCESSORIES on page 16 to order a ground wire and clamp.   
					8. All solvent pails used when flushing, according to your local code.   
					Use only metal pails, which are conductive, placed on a grounded   
					surface. Do not place the pail on a nonconductive surface, such as   
					Y 
					paper or cardboard, which interrupts the grounding continuity   
					.

					To maintain grounding continuity when flushing or relieving pres-   
					sure, always hold a metal part of the gun/valve firmly to the side of a   
					grounded metal pail, then trigger the gun/valve.   
					Z 
					Flushing Safety   
					Before flushing, be sure the entire system and flushing pails are properly   
					grounded. Refer to Grounding, above. Follow the Pressure Relief   
					Procedure on page 2, and remove the spray tip/nozzle from the   
					gun/valve. Always use the lowest possible fluid pressure, and maintain   
					firm metal–to–metal contact between the gun/valve and the pail during   
					flushing to reduce the risk of fluid injection injury , static sparking and   
					splashing.

					WARNING   
					Two accessories are required in your system: a   
					bleed–type master air valve (D) and a fluid drain   
					valve (H). These accessories help reduce the risk of   
					serious bodily injury including fluid injection, splash   
					ing in the eyes or on the skin, and injury from moving   
					parts if you are adjusting or repairing the pump.   
					See pages 16–18 for accessories available from Graco.   
					Be sure all accessories are properly sized to withstand   
					the pressures in the system.   
					- 
					The Typical Installation shown above is only a guide to   
					selecting and installing required and optional accesso-   
					ries. For assistance in designing a system to suit your   
					particular needs, contact your Graco representative.   
					The bleed–type master air valve relieves air trapped   
					between this valve and the pump after the air is shut   
					Trapped air can cause the pump to cycle unex-   
					pectedly. Locate the valve close to the pump.   
					off.   
					The Dimensional Drawing on page 19 provides neces-   
					sary measurements for mounting the pump. If you use an   
					accessory ram (J), as shown in the T ypical Installation,   
					refer to the separate ram manual for mounting dimension   
					requirements.   
					The fluid drain valve assists in relieving fluid pres-   
					sure in the displacement pump, hose and spray gun;   
					triggering the spray gun to relieve pressure may not   
					be sufficient.   
					System Accessories   
					Install the air line accessories in the order shown in the   
					Typical Installation. Working upstream from the pump air   
					inlet, install a pump runaway valve (F) to shut off the air to   
					the pump if the pump accelerates beyond the pread-   
					justed setting. A pump which runs too fast can be seri-   
					ously damaged.   
					Install a fluid drain valve (H) close to the pump fluid outlet.   
					Then connect a grounded fluid supply hose (L). Be-   
					tween the fluid supply hose (L) and the gun/dispensing   
					valve (K), install a whip hose (M) for greater flexibility   
					. 
					NOTE: To use the optional fluid outlet at the base of the   
					Next, install an air line lubricator (E) for automatic air mo   
					- 
					air motor, connect a riser tube between the stan   
					dard outlet and the optional outlet.   
					- 
					tor lubrication, a bleed–type master air valve (D) to re-   
					lieve air trapped between the valve and the pump, an air   
					regulator (C) to control pump speed, and an air line filter   
					(B) to remove harmful dirt and moisture from the com-   
					pressed air supply. Install a second bleed valve (G) on   
					the pump air line to isolate the accessories for servicing.   
					GROUNDING   
					WARNING   
					Before operating the pump, ground the system as   
					explained under FIRE OR EXPLOSION HAZARD   
					and Grounding on page 3.   
					Be sure the pump air line (A) is properly grounded, and is   
					large enough to supply an adequate volume of air to the   
					motor. An air–powered ram (J) requires a separate   
					grounded air supply line (N).

				OPERATION   
					Starting and Adjusting the Pump   
					WARNING   
					1. Make sure the air regulator (C), drain valve (H), and   
					pump bleeder valve (4) are closed.   
					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 pro   
					cedure whenever you shut of f the pump, when   
					checking or servicing any part of the spray/dis-   
					pensing system, when installing, cleaning or   
					changing spray tips/nozzles, and whenever you   
					stop spraying/dispensing.   
					2. Open the bleed–type master air valve (D).   
					- 
					3. Hold a metal part of the gun/valve firmly to the side of   
					a 
					grounded metal pail, and trigger the gun/valve.   
					4. Slowly open the air regulator (C) until the pump starts   
					running slowly and smoothly (about 20 psi [1.4 bar]).   
					Cycle the pump slowly until all the air is purged from   
					the pump and lines.   
					1. Engage the gun/valve safety latch.   
					2. Shut off the air to the pump.   
					3. Close the bleed–type master air valve (re-   
					quired in your system).   
					5. If the pump is not priming properly, open the bleeder   
					valve (4) slightly. Do not open it all the way; the han   
					- 
					4. Disengage the gun/valve safety latch.   
					dle can come off. Cover the bleeder valve hole with   
					something other than your hand or fingers and   
					use it as a priming valve until the fluid appears at the   
					bleeder hole. Close the bleeder valve.   
					5. Hold a metal part of the gun/valve firmly to the   
					side of a grounded 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 (required in your system), having a con-   
					tainer ready to catch the drainage.   
					WARNING   
					To reduce the risk of fluid injection, DO NOT use   
					your hand or fingers to cover the bleeder hole when   
					priming the pump.   
					8. Leave the drain valve open until you are ready   
					to dispense again.   
					If you suspect that the spray tip/nozzle or hose is   
					completely clogged, or that pressure has not been   
					fully relieved after following the 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.   
					6. Release the trigger and engage the safety latch. The   
					pump will stall against pressure.   
					7. In a direct supply system, the pump will start and stop   
					as the gun/valve is opened and closed. In a circulat   
					- 
					ing system, it will run continuously and speed up or   
					slow down as the system demands. Always use the   
					lowest pressure necessary to obtain the desired re   
					- 
					WARNING   
					sults.   
					Moving parts can pinch or amputate your fingers or   
					other body parts. When the pump is operating, the   
					priming piston (located at the pump intake) and the   
					air motor piston (located behind the air motor shield)   
					move. Therefore, NEVER operate the pump with   
					the air motor shield removed, and keep your fingers   
					and hands away from the priming piston.   
					WARNING   
					To reduce the risk of serious bodily injury, including   
					fluid injection and splashing in the eyes or on the   
					skin, and property damage, never exceed the maxi   
					mum air and fluid working pressure of the lowest   
					rated component in your system. See EQUIPMENT   
					MISUSE HAZARD, System Pressure, on page 3.   
					- 
					Before attempting to clear an obstruction from the   
					priming piston or service the pump, follow the Pres   
					- 
					sure Relief Procedure Warning above to prevent   
					the pump from starting accidentally   
					. 
					Never allow the pump to run dry of the fluid being   
					pumped. A dry pump will quickly accelerate to a high   
					speed, possibly damaging itself. If your pump acceler-   
					ates quickly, or is running too fast, stop it immediately and   
					check the fluid supply. If the supply container is empty   
					and air has been pumped into the lines, prime the pump   
					and the lines with fluid, or flush the pump and leave it filled   
					with a compatible solvent. Be sure to eliminate all air from   
					the fluid system.   
					Flush the Pump Before Using   
					This pump was tested with lightweight motor oil which   
					was left in to protect the pump parts. o prevent contami-   
					T 
					nation of the fluid being pumped, flush the pump with a   
					compatible solvent before using it. If the pump is being   
					used to supply a circulating system, allow the solvent to   
					circulate until the pump and lines are thoroughly flushed.   
					Keep the packing nut/wet–cup (21) one–half full with   
					Graco Throat Seal Liquid (TSL), to help prevent the fluid   
					being pumped from drying on the displacement rod and   
					damaging the packings.   
					NOTE: A pump runaway valve (F) can be installed on   
					the air line to automatically shut off the pump if it   
					starts to run too fast.
