and tighten the locknut securely. See Fig. 1. Con-
nect the other end of the wire to a true earth
ground. Order Part No. 237569, Ground Wire and

dations.
4. Spray gun: grounding is obtained through connec-

place the pail on a nonconductive surface, such as
paper or cardboard, which interrupts the grounding
continuity.

relieving pressure , always hold a metal part of the
spray gun firmly to the side of a grounded metal
