WARNING
Proper electrical grounding of every part of your
system is essential. For your safety , read the
warning section, FIRE, EXPLOSION, OR
ELECTROSTATIC SHOCK HAZARD , on page
3. Ground the system as explained there. Then
check
your system as explained below
.
1. Completely turn off the air and fluid supplies to the
gun.
2. Have a qualified electrician check the electrical
grounding
continuity of the spray gun and air hose.
a. With the
electrically conductive air hose con-
nected and properly grounded, use a
megohmmeter to measure the resistance
between the gun manifold and a true earth
ground.
Use an applied voltage of 500 minimum
to
1000 volts maximum.
b. If the resistance is greater than 2 megohms*,
check the tightness of the ground connections,
and be sure the air supply hose ground wire is
connected to a true earth ground. If the resis-
tance is still greater than 2 megohms*, replace
the
air supply hose.
* If you are using the red colored hose, resis-
tance
should not exceed 100 ohms.

Install the Fabric Cover (See Fig 8 )
1. Install a fabric cover over the front of the gun and
slide
it back to
cover the exposed tubing and hoses at
the back of the manifold. See ACCESSORIES

2. Cut
a small slit in the cover and route the two exhaust
tubes
outside the robot
arm or reciprocator
. This en

ables
you to monitor the exhaust tubes
for the pres

ence of any paint or solvent. See Check for Fluid
Leakage
on
page 12. Strap down the exhaust tubes
to
prevent them from moving around.
