Warnings Warnings The following warnings are for the setup, use, maintenance, and repair of this equipment. The exclamation point symbol alerts you to a general warning and the hazard symbols refer to procedure-specific risks. When these symbols appear in the body of this manual or on warning labels, refer back to these Warnings. Product-specific hazard symbols and warnings not covered in this section may appear throughout the body of this manual where applicable.
Warnings WARNING WARNING FIRE AND EXPLOSION HAZARD Flammable fumes, such as solvent and paint fumes, in work area can ignite or explode. To help prevent fire and explosion: • Sprayer generates sparks. Do not spray or flush with flammable liquids. • Use only water-based or oil-based (mineral spirit-type) materials with a flash point greater than 100° F (38° C). • Keep spray area well-ventilated. Keep a good supply of fresh air moving through the area.
Warnings WARNING WARNING EQUIPMENT MISUSE HAZARD Misuse can cause death or serious injury. • Always wear appropriate gloves, eye protection, and a respirator or mask when painting. • Do not operate or spray near children. Keep children away from equipment at all times. • Do not overreach or stand on an unstable support. Keep effective footing and balance at all times. • Stay alert and watch what you are doing. • Do not operate the unit when fatigued or under the influence of drugs or alcohol.

Using Electrical Cords Using Electrical Cords Grounding and Electrical Requirements Sprayer must be grounded. Grounding reduces the risk of static and electric shock by providing an escape wire for electrical current due to static build up or in the event of a short circuit. This 120 Vac sprayer requires a 120 Vac, 60 Hz, 15A circuit with a grounding receptacle. ti3509a Never use an outlet that is not grounded or an adapter.
Common Procedures Common Procedures Trigger Lock Follow the Pressure Relief Procedure whenever you see this symbol. Pressure Relief Procedure Always engage the trigger lock when you stop spraying to prevent the sprayer from being triggered accidentally by hand, or if dropped or bumped. Do not operate or spray near children. Do not aim the sprayer at, or spray any person or animal. Keep hands and other body parts away from the discharge.
Common Procedures Reversible Spray Tip • Thin materials sprayed at high pressure settings may cause the sprayer to enter an operational mode designed to protect it from overheating. This mode is noticeable by the sprayer sounding like it is slowing down and will result in a poor spray pattern. To exit this mode, turn pressure control knob down to lowest pressure setting that results in an acceptable spray pattern. • If spraying in low pressure range, there may not be enough pressure to clear the plug.
Overheating Protection Overheating Protection The motor has a built-in feature to protect itself from overuse. If the motor stops, the thermal switch has tripped. Do not return sprayer to store. The motor will operate normally after cooling for 20-30 minutes. For best results, do not spray more than one cup of water through the tip while cleaning. If more flushing is needed, remove the tip from the sprayer. Sprayer Setup 2. Put prime/spray valve to UP position, then hold trigger in for 10 seconds.
Starting a New Job (or Refilling the Material Cup) Starting a New Job (or Refilling the Material Cup) 1. Engage trigger lock and put prime/spray valve UP to release pressure. ti16700a ti18912a ti14994a If sprayer fails to prime, try one of the steps below: 1. Use the Pump Armor storage/startup tool to clean the inlet valve fitting. See Storage, page 17. ti14999a 2. Install material cup liner, fill with material, and thread onto sprayer. ti15474a ti19536a 2. Clean air vent holes.
Choosing the Correct Tip Choosing the Correct Tip Selecting Tip Hole Size • Tips come in a variety of hole sizes for spraying a range of fluids. The sprayer includes a 0.015 in. (0.38 mm) tip for use in most spraying applications. Use the table below to determine the range of recommended tip hole sizes for each fluid type. • Consider coating and surface to be sprayed. Make sure to use the best tip hole size for the coating and best fan width for that surface.
Install Spray Tip/Guard Assembly (if not installed) Getting Started with Basic Techniques Install Spray Tip/Guard Assembly (if not installed) Use a piece of scrap cardboard to practice these basic spraying techniques before you begin spraying the surface. • This equipment stays pressurized until pressure is manually relieved.
Unclogging Spray Tip/Guard Assembly Aiming Sprayer 3. Aim spray tip of sprayer at bottom edge of previous stroke, overlapping each stroke by half. Aim sprayer at waste area, disengage trigger lock, and put prime/spray valve DOWN to spray position. Pull trigger to clear clog. ti16701a ti18913a ti18917a ti18918a ti14782a ti18925a 4. Spray Pattern Quality A good spray pattern is evenly distributed as it hits the surface.
Shutdown and Cleaning Shutdown and Cleaning 3. Remove flexible suction tube as shown below. The motor has a built-in feature to protect itself from overuse. If the motor stops, the thermal switch has tripped. Do not return sprayer to store. The motor will operate normally after cooling for 20-30 minutes. For best results, do not spray more than one cup of water through the tip while cleaning. If more flushing is needed, remove the tip from the sprayer.
Shutdown and Cleaning 8. Disconnect trigger lock and trigger sprayer for approximately 15 seconds. Engage trigger lock. ti16716a ti18913a 9. 13. Engage trigger lock and put prime/spray valve UP to release pressure. ti18912a Discard contaminated fluid and refill with appropriate flushing fluid. 10. Disengage trigger lock, reverse spray tip to UNCLOG position, and pull trigger for 5 seconds to prime sprayer.
Storage Cleaning Sprayer Exterior • 3. Hold sprayer upside-down over a waste container. Wipe paint off outside of sprayer using a soft cloth moistened with water or flushing fluid. Do NOT submerge the sprayer. Do NOT use solvents with a flash point greater than 100° F (38° C). ti19424a 4. Insert Pump Armor nozzle over material inlet and push firmly until it stops. Squeeze cleaning bottle until Pump Armor flows out drain tube. ti18922a Storage ti18066a ti16700a 5.
