Check solvent cup to be sure it is 1/3 full. 2. Check catalyst and material levels. 3. Inspect material spray tip and O-ring and replace if necessary. 4. Inspect catalyst tip assembly and replace O-rings (if applicable). 5. Inspect tip pin O-rings on front of gun head and replace if nicked or worn. 6. Assemble catalyst tip and material tip onto gun. 7. Lubricate threads on retaining ring and assemble onto gun. 8. Inspect hose assemblies and connections for leaks and wear and tear. Replace if necessary. Do not wait until hose is so worn that it may burst. 9. Check roving quantity. 10. Inspect and replace as necessary: · Chopper blades · Anvil sleeve · Cutter head bearing · Idler bearing 11. Inspect and adjust as necessary: · Cutter head to anvil sleeve tension · Idler bearing to anvil sleeve tension · Check chopper position for most efficient disbursement of chop into spray pattern 12. Oil cutter assembly air motor with MVP oil as necessary (normally 2-3 drops daily depending on usage). PREPARATION AND PRIMING OF “NEW” SYSTEM 1. Be sure all air regulators are turned completely to the left, shutting off air to the components. 2. Slowly open main air. 3. Prime empty catalyst line: · Disengage catalyst pump · Open ball valve on catalyst manifold (if applicable) · Eliminate air pockets by manually hand pumping the catalyst 5-10 short strokes (2-3 in.). After eliminating air pockets, and while continuing to hand pump, close ball valve on catalyst manifold. · Pull and hold trigger on gun while hand pumping catalyst pump with short strokes until there is a solid, steady catalyst flow from the head of the gun. This will ensure that all air is purged from the line. Release trigger. · Continue to hand pump the catalyst with short strokes until catalyst is fully primed and pressurized (generally within 5 additional strokes or less) NOTE: Do NOT engage slave pump until material pump has been primed. 4. Material Pump: (be sure catalyst pump is disengaged) Place a container or bucket under pump valve to catch material while priming. Open ball valve located on bottom of filter assembly on pump. Bring up pressure on material pump gauge just enough to cause stroking of pump. After a smooth flow of material is flowing from valve, close the valve. Once pump is primed, it will stall (stop stroking), and the air may be increased to operating pressures. Generally 30 - 50 psi, depending on output and transfer efficiency desired. 5. Engage slave pump. PREPARATION AND PRIMING OF PREVIOUSLY USED SYSTEM 1. Slowly open main air. 2. Disengage slave pump. 3. Material Pump: (be sure catalyst pump is disengaged) Place a container or bucket under pump valve to catch material while priming. Open ball valve located on bottom of filter assembly on pump. Bring up pressure on material pump gauge just enough to cause stroking of pump. After a smooth flow of material is flowing from valve, close the valve. Once pump is primed, it will stall (stop stroking), and the air may be increased to operating pressures. Generally 30 - 50 psi, depending on output and transfer efficiency desired. 4. Catalyst Slave Pump: · Open ball valve of catalyst manifold (if applicable). · Eliminate air pockets by manually hand pumping the catalyst 5-10 short strokes (2-3 in. strokes each time). While continuing to hand pump, close ball valve on catalyst manifold and continue with short strokes until system is fully primed and pressurized. You should feel a strong resistance in the pump stroke when system is properly primed (generally within 5 additional strokes or less). Engage catalyst pump. AIR PRESSURES 1. Air requirement recommendations: · A minimum of 100 psi on main air. · 15 - 20 CFM for gelcoat systems 2. Material pump: 30 - 50 psi 3. Catalyst Atomizing Air: Catalyst atomizing air should be balanced generally between a range of 15 25 psi. It should be low enough to reduce catalyst over-spray and high enough to atomize catalyst efficiently. This allows user to attain and operate under optimum efficiency. TESTING SPRAY PATTERN Testing of your spray pattern should be performed away from original part. Use paper or cardboard to check the following: · Spray pattern width and output · Catalization · Spray pattern definition (fingers and tails): · Adjust as necessary with the “MVP Air Assist” adjustment screw to give the finest pattern available by eliminating fingers and tails. After completion of the above procedures, you may now confidently use your MVP system Chapter Shut-Down Procedures 1. Trigger gun until pump shaft is in the full down position (at bottom of stroke position). 2. Engage gun trigger lock. 3. Relieving pressures: 2 · Close main air valve to system. · Purge excess air from system by relieving air from the bottom of the air filter or water trap. · Catalyst pressure: “Dump” or relieve catalyst pressure at catalyst manifold (if applicable) by opening catalyst ball valve. Pressure will immediately be relieved. Close the ball valve at once to avoid draining of catalyst from catalyst line. · Material pressure: Place a container under material ball valve at bottom of fluid filter assembly to catch material flow when relieving pressure. Slowly open material ball valve to relieve pressure. Remember - the pump is under extreme pressure. Use the utmost caution when opening the valve to avoid injury or being sprayed with material. Once material pressure is relieved, close ball valve. NOTE: When cleaning gun with solvents, avoid geting solvent in exhause port of “air trigger” gun by covering port with thumb or finger, and pointing gun downward while cleaning. 4. Remove catalyst and material tip assemblies from head of gun and clean thoroughly. 5. Thoroughly clean diffuser cavity in front of gun head. 6. Inspect entire gun and equipment for over spray and clean. System is now “shut-down” and ready for the next start-up Chapter 3 ATC Gun Instructions FEATURES OF THE AT SERIES ACTUATED GUNS There is basically one adjustment on the gun. This is the air refinement adjustment. All adjustments of needles, etc. have been taken out of ht egun. The AT series guns are “air trigger” guns. Air is moved into two chambers in which are located two pistons. The air moves the pistons forward or backward depending on the position of the trigger, e.g. on or off. These air pistons in turn are attached to the needle assemblies. This actuation is what opens and closes the valves. The response is instantaneous. There is no lead or lag of catalyst spraying without resin or vice-versa. The seat, diffuser, and packing arrangement are built into a cartridge assembly for service, adjustment or replacement. The cartridge is removed from the front of the gun. The catalyst valve is the same unique, patented design as on our previous guns. It is also removable from the front of the gun. The air valve for triggering the gun is a 4-way air valve that works the same as the catalyst valve. A rod spool design with the three O-rings opens and closes the air passages to the pistons. The AT series guns are the most advanced state of the art guns introduced to the composites industry. This series features low maintenance, few adjustments and superb quality. The gun will help give you a superior finished product along with few problems, and a long life of service provided you do not soak the gun in acetone. Additional benefits will be seen as the needles are kept out of the spraying atmosphere and enclosed inside the gun. The air section and the fluid section of the gun are separate, avoiding the possibility of fluid in the air section. The guns are light weight, well balanced and feature the patented air assisted airless design. BASIC TROUBLE SHOOTING GUIDE FOR “AT” GUNS Problem Air leaking from exhaust port on back handle while trigger is OFF position. Possible Cause(s) O-ring material worn or cut. Recommended Solution Replace O-rings. O-rings on catalyst piston worn or cut. O-rings on trigger valve worn or cut.

Remember, the orifice tip is brittle . . . it should never be dropped . . . or probed with a sharp metal object. The following steps should be taken to keep the tip clean and ready for use: STEP 1 Immediately after spraying submerge spray tip in solvent until film or coating dissolves completely. STEP 2 Blow out tip with compressed air. STEP 3 Use pointed wooden stick to remove any particles that are left. STEP 4 Inspect carefully through magnifying glass or microscope. Repeat steps 1-3 if necessary. NOTE: All tips have been paint-spray tested. Some orifices are extremely small and barely visible. Check with Step 4.

Chapter 7 Cautions and Warnings AIRLESS EQUIPMENT SAFETY Injection Hazard • DO NOT POINT THE GUN AT ANY PERSON • NEVER LOOK AT THE GUN FROM THE FRONT (NOZZLE END) • NEVER trigger an airless gun while it is aimed at a person. The hydraulic pressure may inject fluid into the flesh, causing injury or death. If the fluid penetrates the skill it WILL cause serious injury. Clothing, such as gloves will NOT provide protection. The system is capable of fluid pressure high enough to cause a LETHAL INJECTION. • TREAT THE APPLICATOR AS YOU WOULD A LOADED WEAPON. Before applying pressure to the system, ALWAYS: • • • • Follow the manufacturer’s operating instructions and maximum pressure recommendations. Secure the trigger in the OFF position and check all pressure connections. Use grounded, high pressure fluid lines. Check that the pump is properly grounded. Before disassembly of ANY part of the pressure system (including the applicator or its nozzle) ALWAYS: • Shut the pump OFF. • Discharge the residual fluid and pressure from the applicator. • Secure the trigger in the OFF position. Follow these same three procedures anytime that operation is discontinued. Do NOT undertake any of the following until pressure is relieved from the entire system: • Loosen or remove the nozzle. • Disassemble any part of the applicator. • Loosen or disconnect any fluid line fittings. • Disassemble any part of the pump. Be sure that the power to the pump is OFF before undertaking ANY repair, maintenance or adjustment. If it is necessary to adjust or clean the nozzle on site, be sure that it is aimed away from all personnel so that it may discharge safely if there is residual pressure in the system. Do NOT use any replacement part that does not meet the manufacturer’s specifications. Correct packing or valve seal leaks IMMEDIATELY. Frequently check the condition of all pressurized components, especailly fluid lines. Replace worn lines and parts before they fail. If nozzle clogging occurs frequently, use a fluid filter with proper mesh size. PUMPING SYSTEM SAFETY INSTRUCTIONS Use MVP replacement parts to assure compatible pressure rating. Read ALL warning and safety instructions carefully before operation of this unit. Heed all warnings. WARNING Never allow any part of the human body to come in front of, or in direct contact with, the material outlet. Accidental operation of the pump could cause an injection into the flesh. If injection occurs, medical aid must be immediately obtained from a physician. Component Rupture: This unit is capable of producing high fluid pressure as stated on the pump model plate. To avoid component rupture, and possible injury, do not exceed 75 cycles per minute or operate at an air inlet pressure greater than 150 PSI (10 bar). Servicing: Before servicing, cleaning or removing any component, ALWAYS disconnect or shut off power source and carefully relieve all fluid pressure from the system. CAUTION: When pumping, flushing or recirculating volatile solvents, the area must be adequately ventilated. CAUTION: Materials and solvent being pumped must be compatible with the parts of the pump that becomes wetted when in contact with material or solvent. Wetted parts consist of the following: stainless steel, copper, brass, steel, gray iron, leather, teflon and vellumoid. CAUTION: Keep solvents away from heat, sparks and open flames. Keep containers closed when not in use. Prevent Static Sparking: If static sparking occurs, fire or explosion could result. The pump, dispensing valve, and containers must be grounded when handling flammable fluids shuch as solvents, paints, lacquers, etc., and wherever discharge of static electricity is a hazard. Use grounded hoses (static wire) and be sure the object being serviced is grounded if it can produce a static charge. Continuity (a good static wire connection) of a hose can be checked by using an ohmmeter. Place one prove on one hose fitting and the other probe on the other hose fitting, continuity or proper grounding through hose is good when a reading is obtained on the ohmmeter. Air and Lube Requirements: Excessive air pressure will shorten the life of the pump. Do not operate pump above recommended maximum air pressure. If necessary, an air regulator should be installed to maintain the desired pressure when the pump is in operation. Filtered and oiled air will allow the pump to operate more efficiently and yield a longer life to operating parts and mechanisms. Keep oiler supplied with MVP Pump Motor Oil. A filter capable of filtering particles larger than 50 microns should be used with an oiler. Maintenance: If the pump is to be inoperative for a lengthy period of time (even for a few hours) disconnect air and relieve all pressure from system. Periodically flush pump with a solvent that is compatible with the material being pumped. Pour a little throat seal lubricant into the solvent cup to keep upper packings pliable and to keep material drag-thru soft. Material drag-thru that is allowed to harden, will scour the piston rod. This will create excessive leakage and rapid packing wear. Disassembly should be done on a clean work bench with clean cloths to keep parts clean. If replacement parts are necessary, consult Parts List for identification. Before assembling, lubricate parts where required. When assembling O-rings, or parts adjacent to O-rings, care must be excercised to prevent damage to O-ring and O-ring groove surfaces.
