General Description

This airless sprayer is a precision power tool used for spraying
many types of materials. Read and follow this instruction
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 starting the engine of a
gas-powered sprayer.

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

attached and secure.

2. Attach the supplied grounding cable to a grounded object.
3. Using a wrench, attach a minimum of 50’ of 1/4” nylon

airless spray hose to the outlet fitting on the filter
assembly. Tighten securely.

4. 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.

5. Turn the pressure control knob fully counterclockwise to

its lowest pressure setting.

6. Make sure the sprayer ON/OFF switch is in the OFF position.
7. Fill the fluid section 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.

8. Check the engine oil level. The gasoline engine oil level

is determined by the manufacturer. Refer to the engine
manufacturer's service manual (supplied).

9. Close the fuel shut-off lever and fill the gas tank with

gasoline. Use only high quality, unleaded gasoline.

Preparing a New Sprayer

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

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

that has a flash point of 60ºC (140ºF) or above.

2. Place the return hose into a metal waste container.
3. Turn the pressure control knob fully counterclockwise to

its lowest pressure setting.

4. Move the PRIME/SPRAY valve to the PRIME position.
5. Move the engine ON/OFF switch to the ON position.
6. Start the engine:

a. Open the fuel valve

lever.

b. Move the throttle

lever away from the
gas tank.

c. Close the engine

choke lever.

d. Holding the frame

with one hand, pull
the starter rope
rapidly and firmly. Continue to hold the rope as you let it
return. Pull and return the rope until the engine starts.

7. Turn on the sprayer by moving

the sprayer ON/OFF switch to
the ON position.

8. Slowly turn the pressure control

knob clockwise to increase the
pressure until fluid starts to
come out of the return hose.
Use only enough pressure to
keep the fluid coming out.

9. Allow the sprayer to run for

15–30 seconds to flush the test fluid out through the
return hose and into the waste container.

10. Turn the pressure control knob fully counterclockwise to

its lowest setting.

11. Turn off the sprayer by moving the sprayer 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 for the material being sprayed (refer to
recommendations of the material manufacturer). An
example of the appropriate solvent is water for latex paint.

2. Place the return hose into a metal waste container.
3. Turn the pressure control knob fully counterclockwise to

its lowest pressure setting.

4. Move the PRIME/SPRAY valve to the PRIME position.

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.
