SAFETY WARNINGS

FOR PROFESSIONAL USE ONLY. OBSERVE ALL WARNINGS

Read and understand all instruction manuals before operating equipment.

EQUIPMENT MISUSE HAZARD

General  Safety

Any misuse of the equipment or accessories, such as
overpressurizing, modifying parts, using incompatible
chemicals and fluids, or using worn or damaged parts,
can cause them to rupture and result in serious bodily in-
jury, including splashing in the eyes or on the skin, fire,
explosion or property damage.

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

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

System Pressure

The 

MAXIMUM WORKING PRESSURE of the agitator

is 100 psi (7 bar). Over-pressurizing the agitator or ac-
cessories could cause a part to rupture. To reduce the
risk of serious bodily injury, including splashing in the
eyes or on the skin, and property damage, NEVER ex-
ceed the maximum air and fluid working pressure of any
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 page. Always read the fluid
and solvent manufacturer’s literature before using the
fluid or solvent with this agitator.

FIRE OR EXPLOSION HAZARD

All electrically conductive objects or devices

 in the

spray area MUST be properly grounded.

When operating the system, any ungrounded objects in
the spray area can become electrically charged. Arcing
may occur if these objects then come in contact or close
to ground. Arcing of sufficient energy levels can ignite the
fluid being sprayed, fumes from solvents, dust particles,
and other flammable substances. This can cause a fire,
explosion, or electrostatic shock and result in serious
bodily injury and property damage.

To ground the agitator,

 remove the grounding screw

(A) and lockwasher (B). See Fig 1. Secure the ground
wire terminal (C) to the agitator with the screw and lock-
washer. Connect the other end of the ground wire to a
true earth ground. See page ACCESSORIES to order a
ground wire and clamp.

MOVING PARTS HAZARD

The rotating helix of the agitator can pinch or amputate
your fingers or other body parts and can cause splashing
in the eyes or on the skin. To reduce this risk, always shut
off the agitator and disconnect the air line before check-
ing or repairing any part of the agitator.

IMPORTANT

United States Government safety standards have been
adopted under the Occupational Safety and Health Act.
These standards – particularly the General Standards,
Part 1910, and the Construction Standards, Part 1926 –
should be consulted.
