dations.
4. Spray gun: ground through connection to a prop-
erly grounded fluid hose and pump.

the fluid supply container.

placed on a grounded surface. Do not place the
pail on a nonconductive surface, such as paper or
cardboard, which interrupts the grounding continu-

relieving pressure, hold a metal part of the spray
gun firmly to the side of a grounded metal pail,
then trigger the gun.
