WARNINGS

FOR PROFESSIONAL USE ONLY. OBSERVE ALL WARNINGS.

Read and understand all instruction manuals, tags,

and warning labels before operating equipment.

EQUIPMENT MISUSE HAZARD

General Safety

Any misuse of the spray equipment or accessories, such
as over pressurizing, modifying parts, using incompatible
chemicals and fluids, or using worn or damaged parts,
can cause them to rupture and result in serious bodily
injury, fire, explosion or property damage.

NEVER point the spray gun at anyone or at any part of
the body. NEVER put hand or fingers over the spray noz-
zle.

ALWAYS follow the Pressure Relief Procedure, at right,
before cleaning or removing the fluid nozzle or servicing
any system equipment.

NEVER try to stop or deflect leaks with your hand or
body.

NEVER alter or modify any part of this equipment; doing
so could cause it to malfunction.

CHECK all spray equipment regularly and repair or
replace worn or damaged parts immediately.

System Pressure

This gun has a 

MAXIMUM WORKING FLUID PRES-

SURE of 300 psi (21 bar), a MAXIMUM WORKING AIR
PRESSURE of 100 psi (7 bar) and a MAXIMUM OPER-
ATING AIR PRESSURE of 15 psi (1.05 bar). NEVER ex-
ceed the maximum working pressure of the gun or any
other component or accessory used in the system.

Fluid Compatibility

BE SURE all fluids and solvents used are chemically
compatible with the “Wetted Parts” shown in the TECH-
NICAL DATA 
on the back cover. Always read the fluid
and solvent manufacturer’s literature before using the
fluid or solvent in this gun.

Pressure Relief Procedure

To reduce the risk of serious bodily injury, including
splashing in the eyes or on the skin or injury from moving
parts, always follow this procedure when shutting off the
system, when checking or servicing any part of the spray
system, when installing, cleaning or changing fluid noz-
zles, and whenever you stop spraying.

1.

Turn off the air and fluid supply to the gun.

2.

Trigger the gun into a grounded metal waste con-
tainer to relieve air and fluid pressure.

HOSE SAFETY

TIGHTEN all fluid connections securely before each use.

NEVER use a damaged hose. Before each use, check
the entire hose for cuts, leaks, abrasion, bulging cover, or
damage or movement of the hose couplings. If any of
these conditions exist, replace the hose immediately.

HANDLE AND ROUTE HOSES CAREFULLY. Do not
pull on hoses to move equipment. Do not use fluids or sol-
vents which are not compatible with the inner tube and
cover of the hose.

IMPORTANT

United States Government safety standards have been adopted under the Occupational Safety and Health Act. These stan-

dards––particularly the General Standards, Part 1910 and the Construction Standards, Part 1926––should be consulted.
