Graco Inc 208008 Adjust the Spray Pattern, Cleaning and Clearing the Spray Tip, Flushing the Gun

Operation

WARNING

SKIN INJECTION HAZARD

To reduce the risk of serious injury, whenever you are instructed to relieve pressure, follow the Pressure Relief

Procedure on page 4.

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

SKIN INJECTION HAZARD

To reduce the risk of a fluid injection injury, never use the gun with the tip guard or trigger guard removed.

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

SKIN INJECTION HAZARD

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.

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.
