Operation

Before Each Use

Check the Spray Tip
Before each use, check the spray tip (22) before
operating the equipment:
• Clean the spray tip as needed. See Clean the
Spray Tip, page 13.
• Adjust the spray tip as needed. See Adjust the
Spray Tip, page 8.
• Replace worn or damaged parts as needed.
Tighten Connections
Before each use, check and tighten all air and fluid
connections before operating the equipment. Replace
worn or damaged parts as needed.
NOTICE
Firmly tighten all fasteners and connections to avoid
air or fluid leaks. Air or fluid leaks may damage
equipment parts.
Lubricate the Equipment
1. Before each day of operation, lubricate the
exposed portion of the needle (19) and the air
piston (16). Use a lubricant compatible with the
fluid being dispensed.
NOTICE
Do not over-lubricate the equipment. Lubricant could
contaminate your fluid supply or other equipment.
Excessive lubrication can also cause the equipment
to malfunction.
2. After lubricating, cover the exposed portions or the
needle (19) and air piston (16) with a piece of plastic
to prevent fluid build-up on these parts.
NOTICE
Fluid buildup on equipment parts could damage the
fluid section. To prevent fluid buildup on equipment
parts, cover exposed equipment parts with a piece of
plastic.

Pressure Relief Procedure

Follow the Pressure Relief Procedure
whenever you see this symbol.
This equipment stays pressurized until pressure is
manually relieved. To help prevent serious injury from
pressurized fluid, such as splashing fluid and moving
parts, follow the Pressure Relief Procedure when
you stop spraying and before cleaning, checking, or
servicing the equipment.
1. Shut off power to the pump (C).
2. Close the bleed-type air valve (E).
3. Close the fluid shutoff valve (Y).
4. Hold a metal part of the gun firmly to a grounded
metal pail. See F . 6.
