Maintenance

Shutdown

1. Relieve Pressure, page 7.

2. Clean the tip and gun as recommended in the sepa-

rate Gun Manual supplied with the gun.

3. If spraying water-based material or a material that

could harden in the sprayer overnight, flush the

sprayer after use. See Flushing, page 8.

Storage

Short Term

1. Flush sprayer with compatible solvent before stor-

ing, then fill the pump and hoses with an oil based

solvent such as mineral spirits.

• For oil base paint: flush with mineral spirits

• For water-base paint: flush with water, then min-

eral spirits and leave the pump, hose and gun

filled with mineral spirits.

Long Term

For longer storage, use Graco Pump Armor or mineral

spirits. Shut off sprayer, Relieve Pressure, page 7, and

make sure prime/pressure relief valve is left open.

Start Up After Storage

Before using water-base paint, flush sprayer with soapy

water and then a clean water flush. When using oil-base

paint, flush out the mineral spirits with the material to be

sprayed.

NOTE: Always store unit indoors.

Maintenance

Daily Maintenance

1. Keep the displacement pump packing nut/wet cup

lubricated with Airlessco TSO (Throat Seal Oil) at all

times. The TSO helps protect the rod and packings.

2. Inspect the packing nut daily. If seepage of paint into

the packing nut and/or movement of the piston

upward is found (while not spraying), the packing

nut should be tightened just enough to stop leakage.

Overtightening will damage the packings and

reduce the packing life.

Electric Motor Maintenance

Lubrication

The motor is supplied with pre-lubricated ball bearings,

lubricated for the life of the bearing.

Motor Brushes

Motor brushes need periodic inspection and replace-

ment as wear indicates. Standard brushes have an ini-

tial length of 1” and should be replaced when they are

worn to a length of 1/2”. Brush wear is greatly influenced

by individual application and it is recommended that

brush wear be checked at early intervals of operation in

order to determine future required inspection.

To change the brushes:

1. Unplug the machine.

2. Remove the cover over the motor, if applicable.

3. Open the two covers at the rear of the motor.

4. Disconnect the brush wire.

5. Pull out the wire.

6. Push the brush retainer clip in and withdraw.

7. Remove the worn brushes.

8. Install new brushes in the reverse order.

To increase brush life, new brushes (Part #331778 for

110 volt) need to have a run in period. After changing

brushes, set the machine for spraying. With a bucket of

Pump Conditioner and water, a 50’ 1/4” airless hose, air-

less gun and tip on unit, open the prime/pressure relief

valve and switch on. The pump will now prime. With

pump running in the prime mode, turn the pressure con-

trol knob to high pressure. (The pump has to cycle fast

with no pressure in the pump). Run the pump for 20 min-

utes and the brushes will be run in.
