Graco Inc. 295533 ユーザーズマニュアル

Check your local electrical code and propor-
tioner manual for detailed grounding instruc-
tions.

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

1. Inspect coupling block gaskets for damage 

and wear. Replace if necessary.

2. With gaskets in place, fit coupling block to 

gun block.

3. Insert coupling block mounting screw and 

tighten securely with 5/16 in. nut driver.

To prevent accidental gun operation, always 
disconnect air supply before servicing gun or 
anytime gun is not in use.

Spraying materials containing isocyanates 
creates potentially harmful mists, vapors, 
and atomized particulates.

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 provid-
ing sufficient ventilation in the work area. If 
sufficient ventilation is not available, a sup-
plied-air respirator is required for everyone in 
the work area.

To prevent contact with isocyanates, appro-
priate personal protective equipment, includ-
ing chemically impermeable gloves, boots, 
aprons, and goggles, is also required for 
everyone in the work area.

To prevent cross-contamination of the gun’s 
wetted parts, do not interchange A compo-
nent (isocyanate) and B component (resin) 
parts. The gun is shipped with the A side on 
the left.
