Operation
WARNING
To reduce the risk of serious injury,
whenever you are instructed to relieve
pressure, follow the Pressure Relief
Procedure on page 4.
SKIN INJECTION HAZARD
Adjust the Spray Pattern
1. To adjust the spray pattern, relieve the pressure.
Engage the safety latch and loosen the tip guard
retaining nut. Turn the spray tip so the groove is
horizontal for a horizontal spray pattern, and
vertical for a vertical pattern. Tighten the nut.
2. The spray tip orifice size and spray angle deter-
mines the coverage and size of pattern. When
more coverage is needed, use a larger spray tip
rather than increasing fluid pressure.
WARNING
To reduce the risk of a fluid injection
injury, never use the gun with the tip
guard or trigger guard removed.
SKIN INJECTION HAZARD
CAUTION
Openings in the tip guard are designed to reduce
paint buildup on the guard while spraying. Any
damage to the sharp edges of the openings causes
paint to collect at that area. To reduce the risk of
damage, never hang the gun by the tip guard.
Cleaning and Clearing the Spray Tip
Clean off the front of the tip frequently during the day’s
operation and at the end of the work day. Always
relieve the pressure and use a solvent soaked brush
to clean the spray tip and to keep fluid buildup from
drying and clogging the spray tip.
If the spray tip clogs while spraying, release the spray
gun trigger, engage the trigger safety, shut off the
pump, and relieve the pressure. Then, remove the air
spray tip and blow out the obstruction with air from the
front of the spray tip, or let the spray tip and gun
nozzle soak long enough to dissolve the obstruction. If
the obstruction will not dissolve, jar it out by tapping
the back of the spray gun against a flat surface.
CAUTION
Never soak the entire gun in solvent. Prolonged
exposure to solvent can ruin the packings.
Flushing the Gun
WARNING
Before flushing, be sure the entire sys-
tem and flushing pails are properly
grounded. Refer to Grounding on page
4. Relieve the pressure and remove the spray
tip from the gun. Always use the lowest possible
fluid pressure, and maintain firm metal-to-metal
contact between the gun and the pail during flush-
ing to reduce the risk of a fluid injection injury,
static sparking, and splashing.
SKIN INJECTION HAZARD
Relieve the pressure, remove the spray tip, and then
flush the gun and spray system with a compatible
solvent. Always flush the gun before the fluid being
sprayed can dry in it.
