Airless Paint Systems

General Safety Information (Cont.)

● Paints and solvents containing

HALOGENATED HYDROCARBONS can

react explosively with aluminum. Do

not use halogenated hydrocarbons

with this equipment. Consult the

paint or solvent product label or

Material Safety Data Sheets (MSDS)

to help determine if it contains

halogenated hydrocarbons.

● Do not use fuels to clean this

equipment.

3.CHANGING FROM WATER-BASED TO OIL-BASED PAINT: Flush with soapy water, then mineral spirits.

4.CHANGING FROM OIL-BASED TO WATER-BASED PAINT: Flush with mineral spirits, followed by soapy water, then a clean water flush.

5.STORAGE: Always relieve pressure (See pressure relief procedure on page 3) prior to storage or when machine is unattended. Follow the storage procedure based on the kind of paint you used:

● Keep spraying area well ventilated.

Keep doors and windows open.

● Remove all ignition sources (i.e.

Static electricity, pilot lights,

cigarettes and electrical arcing).

● Oil-based paint: Flush with mineral

spirits.

● Water-based paint: Flush with

water, then mineral spirits. Leave

the pump, hose and gun filled with

Low Pressure

High Pressure

● Airless spraying can cause static

electricity. Always ground the

pump and spraying surface.

● Do not use solvents containing

halogenated hydrocarbons.

Keep hose away

! CAUTION from sharp objects. Bursting hoses may cause injury. Examine hoses regularly and replace if damaged.

●Check hoses for weak or worn condition before each use, making certain that all connections are secure.

Pre-Operation

FLUSHING

1.NEW SPRAYER: Your sprayer was

factory tested in an oil solution which was left in the pump. Before using oil- based paint, flush with mineral spirits only.Before using water-based paint flush with mineral spirits, followed by soapy water, then a clean water flush.

2.CHANGING COLORS: Flush with a compatible solvent such as mineral spirits or water.

mineral spirits.

● For longer term storage use a 50/50

mixture of mineral spirits and motor

oil. Always ensure that there is no

pressure in the unit, and close the

prime/pressure relief valve for

storage.

Never leave pump

! WARNING unattended while it

is under pressure!

6. START UP AFTER STORAGE: Before using water-base paint, flush with soapy water and then a clean water flush. Before using oil-based paint, flush out the mineral spirits with the material to be sprayed.

HOW TO FLUSH

IMPORTANT COMPONENTS

●Prime/Pressure Relief Valve (Prime/PR Valve, Figure 1). Used to relieve pressure from gun, hose and tip and to prime the unit when in OPEN position.

●Pressure Control Knob (Figure 2). Used to adjust pressure. Turn clockwise to increase pressure and counterclockwise to decrease it.

●Choke Lever, Fuel Valve, and

PROCEDURE

1.Be sure the gun safety lock is engaged and there is no spray tip in the gun.

2.Pour enough clean, compatible solvent into a large,

empty metal pail to fill the pump and hoses.

3.Place the suction tube into the pail or place the pail under the pump.

4.Turn the pressure control knob to low pressure. Refer to Fig. 2.
