INTRODUCTION Your new Airlessco or ALLPRO airless series paint sprayers are designed to meet the demands of the professional painting contractor as well as the homeowner. The famous Airlessco slow-stroking stainless steel piston pump delivers extra long life for the piston, packings, valve seats and balls. The patented Triple-Life packing system is externally adjustable, extending packing life and reducing repacking costs. Its large high-torque electric motor runs slower reducing heat.
WARNINGS MEDICAL ALERT - Airless Spray Wounds If any fluid appears to penetrate your skin, get EMERGENCY MEDICAL CARE AT ONCE. DO NOT TREAT AS A SIMPLE CUT. Tell the doctor exactly what fluid was injected. Have him read the following "NOTE TO PHYSICIAN". WARNING HIGH PRESSURE SPRAY CAN CAUSE EXTREMELY SERIOUS INJURY. OBSERVE ALL WARNINGS. THIS SPRAYER IS FOR PROFESSIONAL USE ONLY.
WARNINGS - CONTINUED HOSES GROUNDING Tighten all fluid connections securely before each use. High pressure fluid can dislodge a loose coupling or allow high pressure spray to be emitted from the coupling and result in an injection injury or serious bodily injury. Use only hose that has a spring guard. The spring guard helps protect the hose from kinks or other damage which could result in hose rupture and cause an injection injury.
WARNINGS - CONTINUED AVOID COMPONENT RUPTURE This sprayer operates at 3000 psi (205 bar). ALWAYS be sure that all components and accessories have a maximum working pressure of at least 3000 psi to avoid rupture which can result in serious bodily injury including injection and property damage. NEVER leave a pressurized sprayer unattended to avoid accidental operation of it which could result in serious bodily injury.
FLUSHING 1. NEW SPRAYER 5. STORAGE Your unit was factory tested in an oil solution which was left in the pump. Before using oil-base paint, flush with mineral spirits only. Before using water-base paint flush with mineral spirits, followed by soapy water, then a clean water flush. 2. CHANGING COLORS Flush with a compatible solvent such as mineral spirits or water. 3. CHANGING FROM WATER-BASE TO OIL-BASE PAINT Flush with soapy water, then mineral spirits. 4.
SETTING UP 1. CONNECT THE HOSE AND GUN a. Remove the plastic cap plug from the outlet and screw a conductive or grounded 3000 psi spray hose onto fluid outlet. b. Connect an airless spray gun to the other end of the hose, but do not install the spray tip yet! NOTE: Do not use thread sealer on swivel unions as they are made to self seal. 2. FILL THE PACKING NUT/WET CUP FIG. 5 Fill the Packing Nut/Wet Cup with 5 drops of Airlessco Throat Seal Oil (TSO). 3.
STARTING UP 2. PREPARE THE MATERIAL a. Prepare the material according to the material manufacturer's recommendations. b. Place the suction tube into the material container. 3. STARTING THE SPRAYER a. Prime/PR Valve must be "OPEN" in the priming position. b. When you have ensured that the gun safety latch is engaged, attach tip and safety guard. c. Turn the engine ON/OFF switch to the "ON" position. d. Turn Pressure Control Knob clockwise to prime the pump. e.
PRESSURE RELIEF PROCEDURE ! IMPORTANT! TO AVOID POSSIBLE SERIOUS BODY INJURY, ALWAYS FOLLOW THIS PROCEDURE WHENEVER THE SPRAYER IS SHUT OFF, WHEN CHECKING IT, WHEN INSTALLING, CHANGING OR CLEANING TIPS, WHENEVER YOU STOP SPRAYING, OR WHEN YOU ARE INSTRUCTED TO RELIEVE THE PRESSURE. 1. Engage the gun safety latch. Refer to the separate instruction manual provided with your gun on its safety features and how to engage safety latch. 4.
AIRLESS SPRAY GUN OPERATION SPRAY Attach spray gun to airless unit and tighten fittings securely. Set the gun safety latch. (Also may be called gun safety lock, or trigger lock) FIG. 7 GUN SAFETY LATCH IN LOCKED POSITION GUN SAFETY LATCH * The gun safety latch should always be set when the gun is not being triggered.

AIRLESS SPRAY TROUBLESHOOTING DEFECTS CAUSE CORRECTION Coarse spray Low pressure Increase the pressure Excessive fogging (overspray) High pressure Material too thin Reduce the pressure to satisfactory pattern distrabution Use less thinner Patten too wide Spray angle too large Use smaller spray angle tip Pattern too narrow Spray angle too small Use larger spray angle tip (if coverage is OK, try tip in same nozzle group) too much material Nozzle too large Material too thin Pressure too high U
TIP SELECTION GUIDE Spray tip selection is based on paint viscosity, paint type, & job needs. For light viscosities (thin paints), use a smaller tip; heavier (thicker paints), use a larger tip size. Spray tip size is based on how many gallons of paint per minute can be sprayed through the tip. Do not use a tip larger than maximum pump flow rate or capacity the sprayer can accommodate. Pump flow rate is measured in gallons per minute (GPM).
REGULAR MAINTENANCE 1. Always stop the pump at the bottom of its stroke when you take a break or at the end of the day. This helps keep material from drying on the rod, damaging the packings. 2. Keep the displacement pump packing nut/wet cup 1/3 full of Airlessco Throat Seal Oil at all times. The TSO helps protect the packings and rod. 3. Lubricate Connecting Rod Pin every 3 months. 4. Inspect the packing nut daily. Your paint pump has Airlessco's patented "Triple Life Packing System".
