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 symbol refers to procedure-specific risk. Refer back to these warnings. Additional, product-specific warnings may be found throughout the body of this manual where applicable.

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:

• Use equipment only in well ventilated area.

• Eliminate all ignition sources; such as pilot lights, cigarettes, portable electric lamps, and plastic drop cloths (potential static arc).

• Keep work area free of debris, including solvent, rags and gasoline.

• Do not plug or unplug power cords, or turn power or light switches on or off when flammable fumes are present.

• Ground all equipment in the work area. See Grounding instructions.

• Use only grounded hoses.

• Hold gun firmly to side of grounded pail when triggering into pail.

• If there is static sparking or you feel a shock, stop operation immediately. Do not use equipment until you identify and correct the problem.

• Keep a working fire extinguisher in the work area.

PRESSURIZED EQUIPMENT HAZARD

Fluid from the gun/dispense valve, leaks, or ruptured components can splash in the eyes or on skin and cause serious injury.

• Follow Pressure Relief Procedure in this manual, when you stop spraying and before cleaning, checking, or servicing equipment.

• Tighten all fluid connections before operating the equipment.

• Check hoses, tubes, and couplings daily. Replace worn or damaged parts immediately.

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. For complete information about your material, request MSDS forms from distributor or retailer.

• Check equipment daily. Repair or replace worn or damaged parts immediately with genuine manufacturer’s replacement parts only.

• Do not alter or modify equipment.

• Use equipment only for its intended purpose. Call your distributor for information.

• Route hoses and cables away from traffic areas, sharp edges, moving parts, and hot surfaces.

• Do not kink or over bend hoses or use hoses to pull equipment.

• Keep children and animals away from work area.

• Comply with all applicable safety regulations.

Warnings

WARNING

MOVING PARTS HAZARD

Moving parts can pinch or amputate fingers and other body parts.

• Keep clear of moving parts.

• Do not operate equipment with protective guards or covers removed.

• Pressurized equipment can start without warning. Before checking, moving, or servicing equipment,

follow the Pressure Relief Procedure in this manual. Disconnect power or air supply.

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 MSDS’s 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.

• Always wear impervious gloves when spraying or cleaning equipment.

PERSONAL PROTECTIVE EQUIPMENT

You must wear appropriate protective equipment when operating, servicing, or when in the operating area of the equipment to help protect you from serious injury, including eye injury, inhalation of toxic fumes, burns, and hearing loss. This equipment includes but is not limited to:

• Protective eyewear

• Clothing and respirator as recommended by the fluid and solvent manufacturer

•Gloves

• Hearing protection

Repair

• To service the pump assembly, see manual

311211.

• To service the air motor, see manual 311238.

• To service the hydraulic motor, see manual

308330.

Hydraulic power supply: follow manufacturer’s recommendations.

Surge tank: use a ground wire and clamp.

Spray gun: ground through a connection to a properly

grounded fluid hose and pump.

Fluid supply container: follow local code.

Grounding

The equipment must be grounded. Grounding reduces the risk of static and electric shock by providing an escape wire for the electrical current due to static build up or in the event of a short circuit.

Pump: Use the ground screw (Z) and lockwasher on the motor to attach ground wire 244524 (Y). Tighten the screw securely. Connect the other end of the ground wire to a true earth ground. See F

IG. 1.

Object being sprayed: follow local code.

Solvent pails used when flushing: follow local code.

Use only conductive metal pails, placed on a grounded surface. Do not place the pail on a nonconductive surface, such as paper or cardboard, which interrupts grounding continuity.

To maintain grounding continuity when flushing or relieving pressure: hold metal part of the spray gun

firmly to the side of a grounded metal pail, then trigger the gun.

Pressure Relief Procedure

1. Engage trigger lock.

2. Air-Powered Pumps only: Close the bleed-type master air valve.

Z Y

TI8250a

FIG. 1

Air and fluid hoses: use only electrically conductive

hoses with a maximum of 500 ft. (150 m) combined hose length to ensure grounding continuity. Check the electrical resistance of hoses. If total resistance to ground exceeds 29 megohms, replace hose immediately.

Air compressor: follow manufacturer’s recommendations.

6 311690M

Hydraulic-Powered Pumps only: Close the hydraulic

supply line valve first, then the return line valve.

3. Disengage the trigger lock.

4. Hold a metal part of the gun firmly to a grounded metal pail. Trigger the gun to relieve pressure.

5. Engage the trigger lock.

6. Open all fluid drain valves in the system, having a waste container ready to catch drainage. Leave drain valve(s) open until you are ready to spray again.

7. If you suspect the spray tip or hose is clogged or that pressure has not been fully relieved after following the steps above, VERY SLOWLY loosen tip

Repair

guard retaining nut or hose end coupling to relieve pressure gradually, then loosen completely. Clear

hose or tip obstruction.

CAUTION

Hydraulic-Powered Pumps only: When shutting down the hydraulic system, always shut off the hydraulic supply line shutoff valve first, and then the return line shutoff valve to prevent overpressurizing the motor or its seals. When starting the hydraulic system, open the return line shutoff valve first.

Disconnect the Lower

To disconnect the lower, follow the procedure on this page. See pages 8-11 for procedures to repair lower. To disconnect pump from an electric circulation assembly, EPXXXX, see manual 311594.

In stand or wall-mounted installations, you do not have to remove the entire pump from its mounting.

1. Relieve the pressure, see Pressure Relief Procedure page 6.

3. Insert the collars (G) into the coupling nut (K). Tighten the coupling nut onto the piston rod (H) and torque to 90-100 ft-lb (122-135 N•m).

4. Flush and test the pump before reinstalling it in the system. Connect hoses and flush the pump. While it is pressurized, check for smooth operation and leaks. Adjust or repair as necessary before reinstalling in the system. Reconnect the pump ground wire before operating.

NXT Pump

Torque to 90-100 ft-lb (122-135 N•m).

Torque to 50-60 ft-lb (68-81 N•m).

Apply anti-seize lubricant.

2. Disconnect the hoses from the lower and plug the ends to prevent fluid contamination.

3. Loosen the coupling nut (K) and remove the collars (G). Remove the coupling nut from the piston rod (H). Unscrew the locknuts (B) from the tie rods (C). Pull the lower (D) off the motor (E). See F F

IG. 3.

IG. 2 and

Reconnect the Lower

If the coupling rod (F) and tie rods (C) have been disassembled from the motor, see Reassemble the Coupling Rod and Tie Rods to the Motor on page 8.

1. Assemble the coupling nut (K) to the piston rod (H).

2. Orient the lower (D) to the motor (E). Position the lower on the tie rods (C). Lubricate the threads of the tie rods. Screw the tie rod locknuts (B) onto the tie rods. Tighten the locknuts and torque to 50-55 ft-lb (68-75 N•m).
