Gun Setup Gun Setup Gun Setup Chec klist See Fig. 11 to locate the elect rostatic gun contro ls. Figure 11 Electrosta tic Gun Controls 1. Turn OFF (O) the ES O n-Off switch (J). 2. Shut off the ai r bleed valve t o the gun. 3. Check g un resistance. See Test Gun Resistan ce, page 32 .
Gun Set up To reduce the risk of a skin in- jection injury, alway s follow the Pressure Relief Proce dure, page 27 , before rem oving or installing the spra y tip, air cap, or tip guar d. 11. The fluid outpu t and pattern widt h depend on the size of the sp ray tip, t he fluid viscosity, and the fluid pr essure.
Gun Setup 19. Check that the ES i ndicator ( K) [Hz indicat or on Smart guns] is li t. See the following table. Table 2 . LED Indi cator Colors Indicator Color Description Green When spraying, the indicat or should remai n green, indicat ing sufficient air pr essure to the alternato r turbine.
Gun Set up Grounding When operating t he electro static gun, any ungrounded object s in the spray area (peop le, containers, tools, etc.) can become elect rically charged. Improper grounding ca n result in stati c sparking, which can cause a fire, explo sion, or electric shock.
Gun Setup • The floor of the spray area: must be electricall y conductiv e and grounde d. Do not cover the floor with cardboar d or any non-conductive mat erial which would in terrupt grounding continuity • Flammabl e liquids i n the spray ar ea: must be kept in approved, grounded contai ners.
