PRESSURIZED EQUIPMENT HAZARD

Fluid from the equipment, leaks, or ruptured compon ents can splash in the eyes o r on skin and cause se rious injury.

• Follow the Pressure Relief Procedure when you stop spraying/dispensing and before cleaning, checking, or servicing equipment.

• Tighten all fluid connections before operating the equipment.

• Check hoses, tubes, and couplings daily. Replace worn or dama ged parts immediately.

• Handle and route hoses and tubes carefully. Keep the hoses and tubes away fr om moving parts and hot surfaces. Do not use the hoses to pull equipment. Do not expose Graco hoses to temperatures above 180°F (82°C) or below -40°F (-40°C).

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:

• Use equipment only in well ventilated area.

• Eliminate all ignition sources; such as pilot lights, cigarettes, portable electric lamps, and plastic drop cloths (potential static arc).

• Keep work area free of debris, including solvent, rags and gasoline .

• Do not plug or unplug power cords, or turn powe r or light switches on or off wh en flammable fumes are present.

• Ground all equipment in the work area. See Grounding instructions.

• Use only grounded hoses.

Setup

NOTICE

This equipment is compatible with most water-based materials. See the wetted parts in the Technical Specifications section and your fluid and solvent manufacturer’s compatibility information.

Prepare the operator

All persons who operate the system should be trained in the safe, efficient operation of all system components as well as the proper handling of the chemical coating. At a minimum, all operators should thoroughly read the safety, installation and operation sections of t his manual and the component manuals.

Setup

Prepare the site

To prevent hazardous concentrations of toxic and/or flammable vapors, spray only in a properly ventilated spray booth. Never operate the spray gun unless ventilation fans are operating. Check and follow all of the national, state and local codes re garding air exhaust velocity requirements.

1. Use a minimum 5 HP (3.7 kW) air compressor for efficient operation.

2. Clear obstacles and debris that could cause an unsafe operating environment.

3. Bring an air line from your compressed air supply to the pressure pot location. Be sure the air is dry and filtered. Install a bleed-type master air valve upstream from the pressure pot. When it is closed and the pressure pot air regulator (33) is opened, the bleed-type master air valve relieves all air pres sure to the equipment components.

4. Ventilate the spray booth.
