Warnings

WARNINGS

SKIN INJECTION HAZARD

High-pressure fluid from gun, hose leaks, or ruptured components will pierce skin. This may look like just a cut, but it is a serious injury that can result in amputation. Get immediate surgical treatment.

• Do not point gun at anyone or at any part of the body.

• Do not put your hand over the spray tip.

• Do not stop or deflect leaks with your hand, body, glove, or rag.

• Do not spray without tip guard and trigger guard installed.

• Engage trigger lock when not spraying.

• Follow Pressure Relief Procedure in this manual, when you stop spraying and before cleaning,

checking, or servicing equipment.

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.

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

Read warnings, page 3.

• The sprayer cord includes a grounding wire with an appro-

priate grounding prong.

• The plug must be plugged into an outlet that is properly installed and grounded in accordance with all local codes

and ordinances.

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

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.
