through connection to a properly grounded fluid

hose and pump.

D Object being sprayed: Follow the local code.

D All solvent pails used when flushing: Follow the

local code. Use only metal pails, which are conduc-

tive. Do not place the pail on a nonconductive

surface, such as paper or cardboard, which inter-

rupts the grounding continuity.

To maintain grounding continuity when flushing or

relieving pressure, always hold a metal part of the gun

firmly to the side of a grounded metal pail, then trigger

the gun.
