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 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.
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.
Installation Installation Grounding 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. The equipment must be grounded.
Installation Accessories Install the following accessories in the order shown in FIG. 2 and FIG. 3, using adapters as necessary. Hydraulic-Powered Pumps For typical installation, see FIG. 3 on page 11. Hydraulic Power Supply Air-Powered Pumps CAUTION The hydraulic power supply must be kept clean at all to avoid damage to the motor and hydraulic power supply. For typical installation, see FIG. 2 on page 10. Accessory Air Control Kits are available for the NXT Air Motor.
Installation Hydraulic Return Line • • • For Viscount I Plus motors, the hydraulic outlet on the motor is 7/8 in., 37° flare. Use a minimum 5/8 in. (16 mm) ID hydraulic return line (J). For Viscount II motors, use a minimum 22 mm (7/8 in.) ID return line (J). The motor has a 1 in. npt(f) hydraulic oil return fitting. Fluid Line • Fluid filter: with a 60 mesh (250 micron) stainless steel element to filter particles from the fluid as it leaves the pump.

Operation Operation Pressure Relief Procedure Pump Operation 1. Engage trigger lock. • 2. Air-Powered Pumps only: Close the bleed-type master air valve. Hydraulic-Powered Pumps only: Shut off the hydraulic supply line valve (S) first, then the return line valve (R). 3. Disengage the trigger lock. CAUTION Do not allow the pump to run quickly for a long period of time as this may damage the packings. • In a direct-supply system, the pump starts when the gun is opened, and stops when the gun is closed.
Maintenance Maintenance Preventive Maintenance Schedule The operating conditions of your particular system determine how often maintenance is required. Establish a preventive maintenance schedule by recording when and what kind of maintenance is needed, and then determine a regular schedule for checking your system. Your maintenance schedule should include the following: Excessive Leaking at Throat If you see excessive leaking at the throat, tighten the packing nut (21), see FIG. 4.
Troubleshooting Troubleshooting 1. Relieve the pressure. 2. Check all possible problems and solutions before disassembling pump. PROBLEM Pump output low on both strokes. Pump output low on only one stroke. Pump operates erratically. CAUSE SOLUTION Restricted air or hydraulic supply lines. Clear any obstructions; be sure all shutoff valve are open; increase pressure, but do not exceed maximum working pressure. Exhausted fluid supply. Refill and reprime pump. Clogged fluid outlet line, valves, etc.
Repair Repair • To service the lower, see manual 311690. • To service the air motor, see manual 311238. • To service the Viscount I Plus hydraulic motor, see manual 308330. • To service the Viscount II hydraulic motor, see manual 308048. Disconnect the Lower tie rods. Tighten the locknuts and torque to 50-55 ft-lb (68-75 N•m). 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.
Repair 4. Align the lower (D) with the tie rods (C) and loosely install the tie rod locknuts (B). Viscount I Plus Pump Shown E 5. Insert the collars (G) and screw the coupling nut (K) onto the coupling rod (F) and torque to 90-100 ft-lb (122-135 N•m). A 6. For Viscount I Plus pumps, torque the holding the adapter plate (J) to the motor (E) to 15-17 ft-lb (20-23 N•m). For Viscount I Plus and Viscount II pumps, torque the tie rod locknuts (B) to 50-55 ft-lb (68-75 N•m).
