EQUIPMENT MISUSE HAZARD
General Safety
Any misuse of the spray/dispensing equipment or accessories, such as 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.
NEVER alter or modify any part of this equipment; doing so could cause it to malfunction.
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.
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.
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.
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.
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. 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 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 chance of igniting fumes still in the air.
If you experience any static sparking or even a slight shock while using this equipment, STOP SPRAYING IMMEDIATELY. Check the entire sys- tem for proper grounding. Do not use the system again until the problem has been identified and corrected.
To ground the pump:
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.

System Pressure
The 10:1 Bulldog Pump develops 1000 psi (70 bar) MAXIMUM WORK- 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.
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’s literature before using fluid or solvent in this pump.
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
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- 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- grounded or poorly grounded hose can make your system hazardous. Also, read FIRE OR EXPLOSION HAZARD, below.
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:
1. | Pump: use a ground wire and clamp. See Fig 1. |
2. | Air hoses: use only grounded air hoses. |
3. | Fluid hoses: use only grounded fluid hoses. |
4. | Air compressor: follow manufacturer’s recommendations. |
5. | Spray gun/dispensing valve: grounding is obtained through con- |
| nection to a properly grounded fluid hose and pump. |
6. | Fluid supply container: according to your local code. |
7. | Object being sprayed: according to your local code. |
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 |
| paper or cardboard, which interrupts the grounding continuity. |
9. | 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. |
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
