dations.

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.

Install the Muffler

The muffler (C, F . 2) is shipped loose. Screw the muf-
IG
fler into the muffler port before installing the pump.

Air and Fluid Hoses

See F . 2. Be sure all air hoses (A, P) and fluid hoses
IG
(R, U) are properly sized and pressure-rated for your
system. Use only electrically conductive hoses. Fluid
hoses must have spring guards on both ends. Use a
swivel (S) between the fluid hose (R) and the gun (T) to
allow easier gun movement.
