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.
Isocyanate Conditions Isocyanate Conditions To prevent exposing ISO to moisture: • Spraying materials containing isocyanates creates potentially harmful mists, vapors, and atomized particulates. • Read material manufacturer’s warnings and material MSDS to know specific hazards and precautions related to isocyanates. • Prevent inhalation of isocyanate mists, vapors, and atomized particulates by providing sufficient ventilation in the work area.

Pressure Relief Procedure Pressure Relief Procedure Trapped air can cause the pump to cycle unexpectedly, which could result in serious injury from splashing or moving parts. 1. Select Park on Pump Control Switch if available, or turn off. Flushing Flush equipment only in a well-ventilated area. Do not spray flammable fluids. Do not turn on heaters while flushing with flammable solvents. • Flush with a fluid that is compatible with the fluid being dispensed and the equipment wetted parts.
Repair Repair a. Remove upper ball cage (12), spring (11), ball (10), o-ring (8) and seat (9). b. Press lower ball (10) off seat (9) from fluid inlet and drain the inlet housing (7). c. Remove o-ring (8), lower ball cage (12), spring (11), ball (10), seat (9), and o-ring (8). Required Tools • • • • • • • • • Large vise Set of adjustable wrenches O-ring pick 1/2 in. bit socket Rubber mallet Torque wrench 2 in. and 3 in.
Repair Pump Disassembly 7. Remove inlet housing (6) from main cylinder (3). Remove crossover tube (4) and o-rings (2). 1. Relieve pressure and flush system. See Pressure Relief Procedure and Flushing, page 7. 2 2. Remove inlet hose and drain inlet housing (7). 2 3. Horizontally clamp pump on outlet housing (7) in vise, use 1/2 in. hex bit socket to loosen all four tie bolts (5) from inlet housing (6). 15 21 clamp here 3 clamp here 21 6 4 r_257891_3a0019_7h 6 8.
Repair 12. Remove throat retainer (19). 16 or 25 19 17 or 26 7 18 20 r_257891_3a0019_10h 13. Use screwdriver and carefully press bearing (16 or 25) and u-cup (17 or 26) out of outlet housing (7). NOTICE To prevent damage to seals, carefully press seals with a screwdriver. 14. If o-ring (20) is leaking, remove throat cartridge (18) and o-ring (20). 15. Clamp flats on seal end of displacement rod (15) in vise. Remove piston retainer (14), bearing (16), and u-cup (17).
Repair Pump Assembly NOTICE To prevent cross-contamination of the equipment’s wetted parts, never interchange component A (isocyanate) and component B (resin) parts. NOTICE To prevent damage to seals always use piston assembly tool (PT) and rod installation tool (RT) from repair kit when assembling the piston seals and displacement rod. NOTE: Piston assembly tool is NOT needed for 10cc-15cc pump sizes. 5.
Repair 7. If the throat cartridge (18) was removed, install o-ring (20) on throat cartridge (18) and lubricate with grease. Apply anti-seize lubricant to throat cartridge (18) threads and install in outlet housing (7). Fully tighten throat cartridge (18) with a wrench. 8. Apply grease to u-cup (17 or 26) and set in throat cartridge (18); ensure u-cup springs face throat cartridge. Set bearing (16 or 25) on top of u-cup (17 or 26). 2 4 2 1 1 3 r_257891_3a0019_15h 16.
Repair 20. Install displacement rod (15) in main cylinder (3) and throat cartridge (18). Gently tap displacement rod with a rubber mallet until piston is flush or below the surface of the main cylinder. 23. Lubricate tie bolt (5) threads and install. Tighten tie bolts evenly in a star pattern until they are flush with the inlet housing (6). 24. Tighten tie bolts (5) evenly in a star pattern to the outlet housing (7).
