Operation
Adjust Spray Pattern
1. To adjust the spray pattern direction with fan tips,
orient the slot in the tip horizontally for a horizontal
pattern and vertically for a vertical pattern. See
Fig. 7.
2. Start the pump. Adjust the fluid pressure until the
spray is completely atomized. Use the lowest
pressure necessary to get the desired results.
Higher pressure may not improve the spray pattern
and will cause premature tip wear and pump wear.
3. The spray tip orifice and spray pattern angle
determines the coverage and size of pattern.
When more coverage is needed, follow the Pres-
sure Relief Procedure on page 9, and install a
larger spray tip rather than increasing fluid pres-
sure.

Adjust a Streaming Tip
Select a tip which will supply a stream at the required
flow rate at the lowest pressure.
Apply the Fluid
Adjust the system control device, if it is automatic, so
the gun starts spraying just before meeting the work-
piece and stops as soon as the workpiece has passed.
Keep the gun a consistent distance, 8 to 10 inches
(200 to 250 mm), from the surface of the object being
sprayed.
Clean the Spray Gun and System Daily
WARNING
INJECTION HAZARD
To reduce the risk of an injection injury
or splashing fluid in the eyes or on the
skin:
D Follow the Pressure Relief Procedure on page
9 before cleaning, removing, or installing a
spray tip and whenever you are instructed to
relieve pressure.
D Do not wipe fluid buildup off the gun or spray tip
until pressure is relieved.
CAUTION
To avoid damaging the gun:
D Never immerse the gun in solvent as this could
damage packings and allow solvent in the air
passages.
D Do not use metal tools to clean holes in the spray
tip.
CAUTION
This gun is not adjustable. To ensure proper shutoff,
screw the piston cap (18) onto the housing (1) until it
bottoms out.
NOTE: Clean the front of the tip frequently during the
day to help reduce buildup.
1. Relieve the pressure as instructed on page 9.
2. Clean the outside of the gun with a soft cloth
dampened with compatible solvent.
3. To avoid damaging the spray tip, clean it with a
compatible solvent and soft brush.
4. If using the internal filter and/or an in-line filter,
remove and clean it thoroughly in a compatible
solvent.
5. Clean the system’s fluid filter and air line filter.
