Warnings
WARNINGS
Pressurized Equipment Hazard
Compressed air can inject in skin. Air tubing rupture can cause injury if disconnected while under pressure. To reduce risk of injury:
• Never exceed maximum working pressure of any attachment.
• Do not direct airstream at body.
• Follow Pressure Relief Procedure
, page 7 whenever you are instructed to relieve pressure, stop
spraying, service equipment, install or clean spray nozzle or disconnect or connect hose.
Cleaning Solvent Hazard with Plastic Parts
Use only compatible water-based solvents to clean plastic structural or pressure-containing parts. Many solvents can degrade plastic parts to the point where they could fail. Such failure could cause serious injury or property damage. See Technical Data
on page 34 of this instruction manual and in all other
equipment manuals. Read fluid and solvent manufacturer’s warnings.
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.
Personal Protective Equipment
Wear appropriate protective equipment when operating, servicing or when in the operating area of this equipment to help protect yourself from serious injury, including eye injury, inhalation of toxic fumes, burns and hearing loss. This equipment includes, but is not limited to:
• protective eye wear
• clothing and respirator as recommended by fluid and solvent manufacturer
• hearing protection
• gloves
CAUTION
Water or material remaining in unit when temperatures are below freezing can damage pump and/or delay startup.
To insure water and material are completely drained out of unit:
• remove hose from material outlet,
• tip sprayer forward 45° to allow material (water) to flow out of pump inlet.
Before adding material or starting unit in cold weather, circulate warm water through pump.

Grounding and Electric Requirements
The sprayer must be grounded. Grounding reduces the risk of electrical shock by providing an escape wire for the electrical current.
WARNING ti4292a
• The sprayer cord includes a grounding wire with an appropriate grounding prong.
K
Ground ti4295a ti4000a
A ti4294a
• The plug must be plugged into an outlet that is properly installed and grounded in accordance with all local codes and ordinances.
• Do not modify plug! If it will not fit in outlet, have grounded outlet installed by a qualified electrician.
ti4296a
• Sprayer model electric require-
Extension Cords
• Only use an extension cord with an undamaged 3-prong plug.
• For up to 100 ft (30.48 m) cord, use 3-wire, 12 AWG (2.5 mm

Preparation
Auxiliary Air Compressor
• Use Auxiliary Air Hookup Kit 287328 when additional atomization air is necessary.
CAUTION
Attaching auxiliary air to sprayer without using the
Auxiliary Air Hookup Kit will damage sprayer.
Generators
7500 W (7.5 KW) minimum.
Tips for Using Generators
• Before running sprayer, make sure it is at room temperature. This will reduce startup current.
• Run generator at full throttle.
Hose Lengths
• The system comes with a twin line hose set consisting of a 1 in. ID x 25 ft (25 mm x 7.6 m) material hose and a 3/8 in. ID air hose. Additional hose sections can be added. Total final length of hose used should not exceed 100 feet in length.
CAUTION
Sprayer air hose fitting can get hot! Allow sprayer to cool down 5 minutes before removing air hose.
