WARNING

GROUNDING

This product must be grounded. In the event of an electrical short circuit, grounding reduces the risk of

electric shock by providing an escape wire for the electric current. This product is equipped with a cord

having a grounding wire with an appropriate grounding plug. The plug must be plugged into an outlet that

is properly installed and grounded in accordance with all local codes and ordinances.

• Improper installation of the grounding plug is able to result in a risk of electric shock.

• When repair or replacement of the cord or plug is required, do not connect the grounding wire to either

flat blade terminal.

• The wire with insulation having an outer surface that is green with or without yellow stripes is the

grounding wire.

• Check with a qualified electrician or serviceman when the grounding instructions are not completely

understood, or when in doubt as to whether the product is properly grounded.

• Do not modify the plug provided; if it does not fit the outlet, have the proper outlet installed by a

qualified electrician.

• This product is for use on a nominal 120V circuit and has a grounding plug similar to the plug

illustrated in the figure below.

• Only connect the product to an outlet having the same configuration as the plug.

• Do not use an adapter with this product.

Extension Cords:

• Use only a 3-wire extension cord that has a 3-blade grounding plug and a 3-slot receptacle that

accepts the plug on the product.

• Make sure your extension cord is not damaged. If an extension cord is necessary, use 12 AWG

(2.5 mm2) minimum to carry the current that the product draws.

• An undersized cord results in a drop in line voltage and loss of power and overheating.

Operation

10 3A1182B

Adjusting the Pressure

When adjusting the pressure, turn the Pressure Control

Knob clockwise to increase pressure and counterclock-

wise to decrease pressure. Always use the lowest pres-

sure necessary to completely atomize the material. If

more coverage is needed, use a larger tip rather than

increasing the pressure.

NOTE: Operating the sprayer at higher pressure than

needed wastes material, causes early tip wear, and

shortens sprayer life.

NOTE: Check the spray pattern. The tip size and angle

determines the pattern width and flow rate.

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.

4. For long tern shutdown or storage, 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 or Graco or Airlessco

Pump Armor.

• 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 or Airlessco Pump Armor.

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.

• To reduce the risk of injection, never hold your

hand, body, fingers or hand in a rag in front of the

spray tip when cleaning or checking for a cleared

tip. Always point the gun toward the ground or into

a waste container when checking to see if the tip is

cleared or when using a self cleaning tip.

• When you spray into the paint bucket, always use

the lowest spray pressure and maintain firm metal

to metal contact between the gun and container.

• To stop the unit in an emergency, turn the engine

off. Then relieve the fluid pressure in the pump and

hose. See Pressure Relief Procedure, page 7
