General Description

This airless sprayer is a precision power tool used for spraying
many types of materials.  Read and follow this Owner’s
Manual carefully for proper operating instructions,
maintenance, and safety information.

Operation

This equipment produces a fluid stream at extremely high

pressure.  Read and understand the warnings in the

Safety Precautions section at the front of this manual

before operating this equipment.

Setup

Perform the following procedure before plugging in the power
cord of an electric sprayer.

1. Ensure that the siphon tube and the return hose are

attached and secure.

2. Using a wrench, attach a minimum of 50’ of 1/4” nylon

airless spray hose to the outlet fitting on the sprayer.
Tighten securely.

3. Attach an airless spray gun to the spray hose.  Using two

wrenches (one on the gun and one on the hose), tighten
securely.

Make sure all airless hoses and spray guns are electrically

grounded and rated at or above the maximum operating

pressure range of the airless sprayer. 

4. Make sure the pressure control knob is turned fully

counterclockwise to its lowest pressure setting.

5. Make sure the ON/OFF switch is in its OFF position.
6. Fill the oil cup with approximately one tablespoon of

separating oil (P/N 0279920).

Never operate unit for more than ten seconds without

fluid.  Operating this unit without fluid will cause

unnecessary wear to the packings.

7. Make sure the electrical service is 120V, 15 amp

minimum.

8. Plug the power cord into a properly grounded outlet at

least 25’ from the spray area.

Always use a minimum 12 gauge, three-wire extension

cord with a grounded plug.  Never remove the third prong

or use an adapter.

Preparing a New Sprayer

If this sprayer is new, it is shipped with test fluid in the fluid
section to prevent corrosion during shipment and storage.
This fluid must be cleaned out of the system thoroughly with
mineral spirits before spraying paint.

Always keep the trigger lock on the spray gun in the

locked position while preparing the system.

1. Place the siphon tube into a container of mineral spirits.
2. Place the return hose into a metal waste container.
3. Set the pressure to minimum by turning the pressure

control knob fully counterclockwise.

4. Move the PRIME/SPRAY valve down to

the PRIME position.

5. Turn on the unit by moving the ON/OFF

switch to the ON position.

6. Allow the sprayer to run for 15–30 seconds

to flush the test fluid out through the return
hose and into the waste container.

7. Turn off the unit by moving the ON/OFF switch to the OFF

position.

Preparing to Paint

Before painting, it is important to make sure that the fluid in the
system is compatible with the paint that is going to be used.

Always keep the trigger lock on the spray gun in the

locked position while preparing the system.

1. Place the siphon tube into a container of the appropriate

solvent.  Examples of the appropriate solvent are water for
latex paint or mineral spirits for oil-based paints.

2. Place the return hose into a metal waste container.
3. Set the pressure to minimum by turning the pressure

control knob fully counterclockwise.

4. Move the PRIME/SPRAY valve down to

the PRIME position.

5. Turn on the sprayer by moving the ON/OFF switch to the

ON position.

6. Allow the sprayer to run for 15–30 seconds to flush the old

solvent out through the return hose and into the metal
waste container.

NOTE: Hold the return hose in the waste

container when moving the

PRIME/SPRAY valve to PRIME in

case the sprayer is pressurized.

CAUTION

NOTE: Incompatible fluids and paint may cause the

valves to become stuck closed, which would

require disassembly and cleaning of the

sprayer’s fluid section.
