Grounding
1. Pump: See F
IG
. 2. Verify that the ground screw
(MS) is attached and tightened securely to the air
motor. Connect the other end of the ground wire (M)
to a true earth ground.
2. Pump fluid hoses: use only electrically conductive
fluid hoses. Check electrical resistance of hoses. If
total resistance to ground exceeds 25 megohms,
replace hose immediately. Genuine Graco hoses
are conductive.
3. Air compressor: follow manufacturer's recommen-
dations.
4. Spray gun: ground through connection to a properly
grounded fluid hose and pump.
5. Fluid supply container: follow your local code.
6. Object being sprayed: follow your local code.
7. Solvent pails used when flushing: follow your local
code. Use only metal pails, which are conductive,
placed on a grounded surface. Do not place the pail
on a nonconductive surface, such as paper or card-
board, which interrupts the grounding continuity.
8. To maintain grounding continuity when flushing or
relieving pressure, hold a metal part of the spray
gun firmly to the side of a grounded metal pail, then
trigger the gun.
Setup
1. If it is necessary to filter the material at the pump
fluid outlet, install optional Fluid Outlet Filter Kit
16V583. See Accessories, page 25, for parts.
a. Use a wrench to hold the pump fluid outlet fitting
in place and a second wrench on the drain valve
tee fitting. Remove drain valve tee fitting (G).
b. Place fluid filter (401) in a vise. Apply thread
sealant on threads and install fittings as shown.
2. See F
IG
. 1. Attach end of fluid hose (J) to pump out-
let (L), or filter, and tighten.
3. Attach other end of fluid hose (J) to reducing nipple
and whip hose (K). Attach whip hose to gun and
tighten.
4. Close bleed type master air valve (C). Connect air
supply hose to air inlet.
5. Verify that suction hose fittings are tight.
6. Flush before using. See page 10.
7. Prime before using. See page 11.
The equipment and flush pail must be grounded to
reduce the risk of static sparking. Static sparking can
cause fumes to ignite or explode. Grounding provides
an escape wire for the electric current.
