Setup

WARNING

If you supply your own hoses and spray gun, be sure the hoses are electrically conductive, that the gun has a tip guard, and that each part is rated for at least 3000 psi (210 bar, 21 MPa) Working Pres- sure. This is to reduce the risk of serious injury caused by static sparking, fluid injection or over- pressurization and rupture of the hose or gun.

CAUTION

To avoid damaging the pressure control, which may result in poor equipment performance and compo- nent damage, follow these precautions:

1.Always use a nylon spray hose at least 50 ft. (15 m) long.

2.Never use a wire braid hose as it is too rigid to act as a pulsation dampener.

3.Never install any shutoff device between the filter and the hose. See Fig. 2.

1.Connect the hose (74) and gun (67) and screw it onto the outlet nipple (28). Don't use thread sealant, and don't install the spray tip yet!

2.Fill the wet±cup (102). Pry off the wet-cup seal. Fill the cup 1/3 full with Graco Throat Seal Liquid (TSL), supplied. Install the wet-cup seal.

3.Plug in the sprayer. Be sure the ON/OFF switch

(52)is OFF. Plug the cord into a grounded outlet at least 20 feet away from the spray area.

WARNING

FIRE AND EXPLOSION HAZARD

Proper electrical grounding is essential to reduce the risk of fire or explosion which can result in serious injury and property damage. Also read FIRE OR EXPLOSION HAZARD on page 2

4.Flush the pump to remove the lightweight oil which was left in to protect pump parts after fac- tory testing. See page 12.

5.Prepare the paint according to the manufacturer's recommendations. Remove any paint skin. Strain the paint through a fine nylon mesh bag (available at most paint dealers) to remove particles that could clog the spray tip. This is an important step toward trouble-free paint spraying.
