PRESSURE RELIEF PROCEDURE
OPERATING INSTRUCTIONS
Follow all instructions above, be sure that fittings at pump outlet and at gun are tight. Use two wrench to
tighten the maing fitting.
Fill the packing nut with oil to help prolong the packing life.
• Turn on the air to the pump (fig.1), but the position of this valve must to be ‘’close air’’.
• Check that the A, B and C valves are in position ‘’1’’ before open the air valve.
The pump must be connected to ground with a ground wire which is supplied with the
pump (4 mm
2
of section and a clamp).
SPRAY GUN: Obtain grounding through connection to a properly grounded fluid
hose and pump.
OBJECT BEING SPRAYED: Use ground wire and clamp.
AIR COMPRESOR: Follow air compressor manufacturer’s recommendations.
Use
ONLY METAL PAILS
, which are conductive. Do not place the pail on a non-
conductive surface, such as paper or cardboard, which interrupts the grounding
continuity
.

FIRE HAZARD
Static electricity is created by the high velocity flow of fluid through the pump and hose. If every
part of spray equipment is not properly grounded, sparking may occur, and the system may become
hazardous. Check the entire system for positive grounding.
GROUNDING
Before starting to work the pump must be connected to ground:
