Wagner SprayTech 0295001 7

WARNING

Always spray at minimum pressure with the gun nozzle tip removed when using mineral spirits or any other solvent to clean the pump, hose, or gun. Static electricity buildup may result in a fire or explosion in the presence of flammable vapors.

Maintaining the Fluid Section

Servicing the fluid section includes replacing the T-lip packings, the piston, and valve parts that show signs of wear.

NOTE: If any parts are difficult to disassemble, soak them in an appropriate solvent until the paint softens.

Flushing the Unit

Flush the unit with the solvent appropriate to the material being used after daily use (use solvents at room temperature). The unit should then be flushed again with mineral spirits.

For long term storage, flush the unit with an appropriate oil before storing.

1.Follow the pressure relief procedure found earlier in this manual.

2. Turn the PRIME/SPRAY valve to SPRAY to bleed off any pressure remaining in the pump.

3. Remove the gun tip and
clean with a solution
appropriate to the type of
material being sprayed.	PRIME/SPRAY Valve

4.	Remove the material
	container and replace it with a container of solvent
	appropriate to the type of material being sprayed.
5.	Check to be sure the pressure control knob is turned fully
	counterclockwise to its lowest setting.
6.	Turn the power switch to ON.
7.	Trigger the spray gun into a waste container until solvent
	comes out and the pump, hose, and gun are clean.

Removing the Fluid Section

1.Using a flat blade screwdriver, pry the retaining ring out of the bottom of the inlet valve housing and remove the suction set assembly.

2.Unscrew the fluid hose from the fluid section assembly.

3.Loosen and turn the return line fitting away from the fluid section assembly.

4.Unscrew the 6 screws holding the cover to the front of the pump housing and remove the cover.

5.Pull the retaining clip from the yoke and pin.

6.Push the pin out of the piston and yoke. Use the short end of a hex wrench if necessary.

7.Loosen the locknut at the top of the fluid section assembly.

8.Unscrew the fluid section assembly from the pump.

Maintenance

Daily Maintenance

Perform the following procedures daily.

Filling the Packing Nut Reservoirs With Oil

Maintaining the T-lip Packings

Removing the T-lip Packings

1.Place the wrench flats of the inlet valve housing into a vise and unscrew the fluid section from the inlet valve housing.

2.Unscrew the packing nut from the fluid section.

NOTE: When removing the piston, keep the piston from falling or the piston may be damaged.

3.Push the piston out through the lower end of the fluid section. Tap the top of the piston with a rubber mallet if necessary.

Before you start to spray each day, squirt a lubricant such as hydraulic oil into the slots in the upper pump housing. Household oil and cooking oil also work when hydraulic oil is not available.

NOTE: Do not apply so much that it overflows and drips into the paint.

This lubricant keeps the piston seals pliant, minimizing paint bypass and piston wear. If the unit is operated several hours a day, lubricate approximately every 4 hours.

4. Remove the upper and

lower spacers from the fluid

section.

5. Push the T-lip packings out

of the fluid section with a

screwdriver. To push out

the upper seal, insert the

screwdriver through the

lower end of the fluid

section. To push out the
