INTRODUCTION The SL1500 sprayer is the choice of the high volume contractors that need a machine that can pump extremely heavy materials like wallboard mud and waterproofing coatings. Their most popular application is spraying a skim coat of wallboard mud to give a Level 5 finish using the supplied size 627 REV-TIP. Utilizing the proven SL pump platform in conjuction with an oversized bottom mounted foot valve, it delivers unprecedented suction.
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 GROUNDING HOSES 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 Oil-base paint: Flush with mineral spirits.
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 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".
