Isocyanate Hazard

Isocyanate Hazard

Spraying materials containing isocyanates creates potentially harmful mists, vapors, and atomized par- ticulates.

Read material manufacturer’s warnings and material MSDS to know specific hazards and precautions related to isocyanates.

Prevent inhalation of isocyanate mists, vapors, and atomized particulates by providing sufficient ventila- tion in the work area. If sufficient ventilation is not available, a supplied-air respirator is required for everyone in the work area.

To prevent contact with isocyanates, appropriate per- sonal protective equipment, including chemically impermeable gloves, boots, aprons, and goggles, is also required for everyone in the work area.

Keep A and B

Components

Separate

CAUTION

To prevent cross-contamination of the gun’s wetted parts, do not interchange A component (isocyanate) and B component (resin) parts. The gun is shipped with the A side on the left. The fluid manifold, fluid housing, check valve cartridge, and mix module are marked on the A side.

Grounding

WARNING

Read warnings, page 10.

Check your local electrical code and proportioner man- ual for detailed grounding instructions.

Ground the spray gun through connection to a Graco-approved grounded fluid supply hose.

Piston Safety Lock

Engage piston safety lock whenever you stop spray- ing, to avoid accidental triggering.

WARNING

Read warnings, page 9.

To engage piston safety lock: push knob in and turn clockwise. When engaged, piston safety lock allows some purge rod movement but shuts off fluid flow and gun cannot spray. To disengage piston safety lock:

TI3850a

push knob in and turn counterclockwise until it pops out.

TI3849a

Loss of Air Pressure

In event of loss of air pressure while gun is triggered, gun will continue to spray. To shut off gun, do one of the following:

Push hard or hit end of safety lock, to engage piston safety lock.

TI4022a

Close fluid valves A and B.

TI3837a
