Operation
7. Open all fluid drain valves (N) in the system. Have a
waste container ready to catch drainage. Leave
drain valves open until ready to spray again.
8. If the spray tip or line is clogged, or if the pressure
has not been fully relieved:
a. Very slowly loosen the tip retaining nut (23) or
the fluid line clamp (AC) to gradually relieve
pressure. See F
IG
b. Remove the tip retaining nut (23) or the fluid line
clamp (AC) completely.
c. Clear the obstruction in the line or tip.
Start and Adjust the Equipment
To avoid injury from pressurized fluid, such as
splashing fluid and moving parts:
•
Do not put your hand in front of the spray tip.
•
Keep fingers away from moving parts, such as the
needle (19).
•
Do not exceed the maximum fluid pressure rating.
See Technical Specifications, page 22.
1. Confirm that the equipment is properly grounded.
See Grounding, page 6.
2. Check the spray tip (22) before operating the
equipment. See Check the Spray Tip, page 9.
3. Check and tighten the tip retaining nut (23) before
operating the equipment. Replace worn or
damaged parts as needed.

. 6.
4. Check and tighten all air and fluid connections
before operating the equipment. Replace worn or
damaged parts as needed.
NOTICE
Firmly tighten all connections to avoid air or fluid
leaks. Air or fluid leaks may damage equipment
parts.
5. Set the timer (S) so that the gun will start spraying
before meeting the workpiece (V) and stop spraying
just after the workpiece has passed.
6. Set the actuating air to a minimum of 50 psi (325
kPa, 3.4 bar). Do not exceed 200 psi (1.4 MPa,
14 bar)
7. Start the pump. See your separate pump manual.
8. Adjust the pump speed and pressure to modify
atomization.
NOTE: Use the lowest pump speed and pressure
necessary for the desired results. Higher speed or
pressure may not improve the spray pattern and
will cause premature tip wear and pump wear.
NOTICE
To prevent equipment damage, do not increase
pump pressure to increase spray coverage. Instead,
use a larger spray tip.
NOTE: The spray tip orifice size and angle determine
coverage and pattern. See Adjust the Spray Pattern,
page 8, and Adjust the Spray Coverage, page 8.
