This sprayer operates at 3000 psi (205 bar). 

ALWAYS 

be 

sure that all components and accessories have a maximum 

working pressure of at least 3000 psi to avoid rupture 

which can result in serious bodily injury including injection 

and property damage.

NEVER 

leave a pressurized sprayer unattended to avoid 

accidental operation of it which could result in serious 

bodily injury.

ALWAYS 

follow the 

PRESSURE RELIEF PROCEDURE 

whenever you stop spraying and before adjusting, 

removing or repairing any part of the sprayer.

NEVER 

alter or modify any part of the equipment to avoid 

possible component rupture which could result in serious 

bodily injury and property damage.

NEVER 

use weak or damaged or non-conductive paint 

hose. Do not allow kinking or crushing of hoses or allow it 

to vibrate against rough or sharp or hot surfaces. Before 

each use, check hoses for damage and wear and ensure 

all fluid connections are secure.

REPLACE 

any damaged hose. 

NEVER 

use tape or any 

device to mend the hose.

NEVER 

attempt to stop any leakage in the line or fittings 

with your hand or any part of the body. Turn off the unit 

and release pressure by following 

PRESSURE RELIEF 

PROCEDURE.

ALWAYS 

use approved high pressure fittings and 

replacement parts.

ALWAYS 

ensure fire extinquishing equipment is readily 

available and properly maintained.

IMPORTANT: 

 United States Government safety standards 

have been adopted under the Occupational Safety & Health 

Act.  These  standards,  particularly  the  General  Standards, 

Part 1910, & the Construction Standards, part 1926 should 

be consulted.

 

 

      

WHEN SPRAYING & CLEANING WITH FLAMMABLE PAINTS OR THINNERS:

1.  When spraying with flammable liquids, the unit must be located a minimum of 25 feet away from the spraying area in  

 

a well ventilated area. Ventilation must be sufficient enough to prevent the accumulation of vapors.

2.  To eliminate electrostatic discharge, ground the spray unit, paint bucket and spraying object. Use only high    

 

pressure airless hoses approved for 3000 psi which is conductive.

3.   Remove spray tip before cleaning gun and hose. Make contact of gun with bucket and spray without the tip in a well  

 

ventilated area, into the grounded steel bucket.

4.   Never use high pressure in the cleaning process. 

USE MINIMUM PRESSURE.

5.   Do not smoke in spraying/cleaning area.

Reduce the risk of injection injury, static sparking or 

splashing by following the specific cleaning procedure on 

page 5.  

ALWAYS 

follow the 

PRESSURE RELIEF PROCEDURE

 

on page 8. 

ALWAYS 

remove the spray tip before flushing. Hold a 

metal part of the gun firmly to the side of a metal pail and 

use the lowest possible fluid pressure during flushing.

NEVER 

use cleaning solvents with flash points below 140 

degress F. Some of these are: acetone, benzene, ether, 

gasoline, naphtha. Consult your supplier to be sure.

NEVER SMOKE IN THE SPRAYING/CLEANING AREA.

ALWAYS 

be sure all equipment and objects being sprayed 

are properly grounded. 

ALWAYS 

ground sprayer, paint bucket and object being 

sprayed. See "grounding" on page 3 for detailed grounding 

information. Vapors created when spraying can be ignited 

by sparks. To reduce the risk of fire, always locate the 

sprayer at least 20 feet (6 m.) away from the spray area. 

DO NOT

 plug in or unplug any electrical cords in the spray 

area, which can create sparks, when there is any chance of 

igniting vapors still in the air. Follow the coating & solvent 

manufacturers safety warnings and precautions.

Use only conductive fluid hoses for airless applications. Be 

sure gun is grounded through hose connections. Check 

ground continuity in hose & equipment. Overall (end to 

end) resistance of unpressurized hose must not exceed 29 

megohms for any coupled length or combination of hose 

length. Use only high pressure airless hoses with static 

wire approved for 3000 psi.

WARNING

: Do not use halogenated solvents in this system. 

The prime valve, 2 gun manifold and most airless guns have 

aluminum parts and may explode. Cleaning agents, coatings, 

paints or adhesives may contain halogenated hydrocarbon 

solvents.  DON"T  TAKE  CHANCES!  Consult  your  material 

suppliers  to  be  sure.  Some  of  the  most  common  of  these 

solvents  are:  Carbontetrachloride,  Chlorobenzene,  Dichlo-

roethane,  Dichloroethyl  Ether,  Ethylbromide,  Ethylchloride, 

Tethrachloethane. Alternate valves and guns are available if 

you need to use these solvents.
