Before operating the pump, ground the
system as explained below. Also read
the section FIRE AND EXPLOSION
HAZARD on page 5.
1. King Pumps: use a ground wire and clamp. See
Fig. 1. Remove the ground screw (Z) and insert
through eye of ring terminal at the end of ground
wire (Y). Fasten ground screw back onto pump
and tighten securely. Connect the other end of the
wire to a true earth ground. Order Part No. 222011
Ground Wire and Clamp.
All Other Pumps: use a ground wire and clamp.
See Fig. 2. Loosen the grounding lug locknut (W)
and washer (X). Insert one end of a 1.5 mm@ (12
ga) minimum ground wire (Y) into the slot in lug (Z)
and tighten the locknut securely. Connect the other
end of the wire to a true earth ground. Order Part

m) combined hose length to ensure grounding
continuity. Check the electrical resistance of your
hoses at least once a week. If the total resistance
to ground exceeds 29 megohms, replace the hose
immediately.
NOTE: Use a meter that is capable of measuring
resistance at this level.

placed on a grounded surface. Do not place the
pail on a nonconductive surface, such as paper or
cardboard, which interrupts the grounding continu-
ity.
relieving pressure, hold a metal part of the spray
gun firmly to the side of a grounded metal pail,
then trigger the gun.
