Warnings Warnings The following warnings are for the setup, use, grounding, maintenance, and repair of this equipment. The exclamation point symbol alerts you to a general warning and the hazard symbols refer to procedure-specific risks. When these symbols appear in the body of this manual or on warning labels, refer back to these Warnings. Product-specific hazard symbols and warnings not covered in this section may appear throughout the body of this manual where applicable.
Warnings WARNING WARNING FIRE AND EXPLOSION HAZARD Flammable fumes, such as solvent and paint fumes, in work area can ignite or explode. To help prevent fire and explosion: • Do not spray flammable or combustible materials near an open flame or sources of ignition such as cigarettes, motors, and electrical equipment. For X5 and X7 models: only use water-based or mineral spirit-type materials with a flash point greater than 100° F (38° C).
Warnings WARNING WARNING EQUIPMENT MISUSE HAZARD Misuse can cause death or serious injury. • • Do not operate the unit when fatigued or under the influence of drugs or alcohol. Do not exceed the maximum working pressure or temperature rating of the lowest rated system component. See Technical Data in all equipment manuals. • Use fluids and solvents that are compatible with equipment wetted parts. See Technical Data in all equipment manuals. Read fluid and solvent manufacturer’s warnings.
Warnings WARNING WARNING TOXIC FLUID OR FUMES HAZARD Toxic fluids or fumes can cause serious injury or death if splashed in the eyes or on skin, inhaled, or swallowed. • Read MSDSs to know the specific hazards of the fluids you are using. • Store hazardous fluid in approved containers, and dispose of it according to applicable guidelines.

Grounding and Electrical Requirements Grounding and Electrical Requirements Fluid supply container: follow local code. Sprayer must be grounded. Grounding reduces the risk of static and electric shock by providing an escape wire for electrical current due to static build up or in the event of a short circuit. • • Grounding the metal pail: connect a ground wire to the pail by clamping one end to pail and other end to ground such as a water pipe.
Operation Operation See Operation manual for basic information on sprayer setup, flushing, and storage. 2. Move Prime/Spray valve to PRIME to relieve pressure. Trigger Lock Always engage the trigger lock when you stop spraying to prevent the gun from being triggered accidentally by hand or if dropped or bumped. ti9346a ti13961a A20 Only 3. Hold gun firmly to side of pail. Trigger the gun to relieve pressure. ti8908a ti8909a Trigger Locked Trigger Unlocked ti9207a Pressure Relief Procedure 4.
General Repair Information General Repair Information Flammable materials spilled on hot, bare, motor could cause fire or explosion. To reduce risk of burns, fire or explosion, do not operate sprayer with cover removed. • Keep all screws, nuts, washers, gaskets, and electrical fittings removed during repair procedures. These parts usually are not provided with replacement kits. • Test repairs after problems are corrected.
Basic Troubleshooting Basic Troubleshooting Check everything in this Basic Troubleshooting table before you bring the sprayer to a Graco/MAGNUM authorized service center. Problem Power switch is on and sprayer is plugged in, but motor does not run, and pump does not cycle. Cause Solution Pressure is set at zero pressure. Turn pressure control knob clockwise to increase pressure setting. Motor or control is damaged. Take sprayer to Graco/MAGNUM authorized service center.
Basic Troubleshooting Problem Pump does not prime. Cause Solution Prime/Spray Valve is in SPRAY posi- Move Prime/Spray Valve to PRIME tion. position. Inlet screen is clogged or suction tube is not immersed in fluid. Clean debris off inlet screen and make sure suction tube is immersed in fluid. Pump was not primed with flushing fluid. Remove suction tube from paint. Prime pump with water or solvent-based flushing fluid, see Operation manual. Inlet valve check ball is stuck.
Basic Troubleshooting Problem Pump cycles but does not build up pressure. Pump cycles, but paint only dribbles or spurts when spray gun is triggered. 332694A Cause Solution Pump is not primed. Prime pump. Inlet screen is clogged. Clean debris off inlet screen and make sure suction tube is immersed in fluid. Suction tube is not immersed in paint. Make sure suction tube is immersed in paint. Suction tube is leaking. Tighten suction tube connection. Inspect for cracks or vacuum leaks.
Basic Troubleshooting Problem Cause Pressure is set at maximum but can- Reversible spray tip is in UNCLOG not achieve a good spray pattern. position. Spray tip is too large for sprayer. Solution Rotate arrow-shaped handle on spray tip so it points forward in SPRAY position, see Operation manual. Select smaller spray tip. Spray tip is worn beyond capability of Replace spray tip. sprayer. Extension cord is too long or not heavy enough gauge. Replace extension cord.
Basic Troubleshooting Problem Cause Fan pattern varies dramatically while Pressure control switch is worn and causing excessive pressure variaspraying. tion. OR Solution Take sprayer to Graco/MAGNUM authorized service center. Sprayer does not turn on promptly when resuming spraying. Cannot trigger spray gun. Spray gun trigger lock is locked. Rotate trigger safety lever to unlock trigger lock, page 13. Paint is coming out of pressure control switch. Pressure control switch is worn.
Advanced Troubleshooting Advanced Troubleshooting See Basic Troubleshooting first, page 15 for problems that are more easily remedied. Motor Does Not Operate Specific Problem Basic mechanical problems. 20 Cause Solution Paint is frozen or hardened in pump. See Basic Troubleshooting, page 15. Gears are damaged. Remove motor enclosure and rotate motor fan to check for bad gears. If gears bind or slip, remove pump cover and replace failed gears. See List of Kits, page 30.
Advanced Troubleshooting Specific Problem Basic electrical problems. Cause Solution Motor overheated. Allow motor to cool for 45 minutes. Retry. Electrical outlet is damaged. Reset building circuit breaker or replace fuse. Try another outlet. Check electric supply with volt meter. Meter must read 220/240 VAC. If voltage is too high, do not plug sprayer in until outlet is corrected. Control board leads are improperly fastened, improperly mated, or corroded. Replace any loose terminals.
