Warnings
The following warnings are for the setup, use, grounding, maintenance, and repair of this equipment. The
exclamation point symbol alerts you to a general warning and the hazard symbols refer to procedure-specific risks.
When these symbols appear in the body of this manual or on warning labels, refer back to these Warnings.
Product-specific hazard symbols and warnings not covered in this section may appear throughout the body of this
manual where applicable.
WARNING
FIRE AND EXPLOSION HAZARD
Flammable fumes, such as solvent and paint fumes, in work area can ignite or explode. Paint or
solvent flowing through the equipment can cause static sparking. To help prevent fire and explosion:
•Use equipment only in well-ventilated area.
•Eliminate all ignition sources, such as pilot lights, cigarettes, portable electric lamps, and plastic drop
cloths (potential static sparking).
•Ground all equipment in the work area. See Grounding instructions.
•Never spray or flush solvent at high pressure.
•Keep work area free of debris, including solvent, rags and gasoline.
•Do not plug or unplug power cords, or turn power or light switches on or off when flammable fumes
are present.
•Use only grounded hoses.
•Hold gun firmly to side of grounded pail when triggering into pail. Do not use pail liners unless they
are anti-static or conductive.
•Stop operation immediately if static sparking occurs or you feel a shock. Do not use equipment until
you identify and correct the problem.
•Keep a working fire extinguisher in the work area.
FIRE AND EXPLOSION HAZARD
Static charge may build up on plastic parts during cleaning and could discharge and ignite flammable
vapors. To help prevent fire and explosion:
•Clean plastic parts only in well-ventilated area.
•Do not clean with a dry cloth.
•Do not operate electrostatic guns in equipment work area.
Warnings
4 3A9126A
SKIN INJECTION HAZARD
High-pressure fluid from gun, hose leaks, or ruptured components will pierce skin. This may look like
just a cut, but it is a serious injury that can result in amputation. Get immediate surgical treatment.
•Do not spray without tip guard and trigger guard installed.
•Engage trigger lock when not spraying.
•Do not point gun at anyone or at any part of the body.
•Do not put your hand over the spray tip.
•Do not stop or deflect leaks with your hand, body, glove, or rag.
•Follow the Pressure Relief Procedure when you stop spraying and before cleaning, checking, or
servicing equipment.
•Tighten all fluid connections before operating the equipment.
•Check hoses and couplings daily. Replace worn or damaged parts immediately.
MOVING PARTS HAZARD
Moving parts can pinch, cut or amputate fingers and other body parts.
•Keep clear of moving parts.
•Do not operate equipment with protective guards or covers removed.
•Equipment can start without warning. Before checking, moving, or servicing equipment, follow the
Pressure Relief Procedure and disconnect all power sources.
EQUIPMENT MISUSE HAZARD
Misuse can cause death or serious injury.
•Do not operate the unit when fatigued or under the influence of drugs or alcohol.
•Do not exceed the maximum working pressure or temperature rating of the lowest rated system
component. See Technical Specifications in all equipment manuals.
•Use fluids and solvents that are compatible with equipment wetted parts. See Technical
Specifications in all equipment manuals. Read fluid and solvent manufacturer’s warnings. For
complete information about your material, request Safety Data Sheets (SDSs) from distributor or
retailer.
•Do not leave the work area while equipment is energized or under pressure.
•Turn off all equipment and follow the Pressure Relief Procedure when equipment is not in use.
•Check equipment daily. Repair or replace worn or damaged parts immediately with genuine
manufacturer’s replacement parts only.
•Do not alter or modify equipment. Alterations or modifications may void agency approvals and create
safety hazards.
•Make sure all equipment is rated and approved for the environment in which you are using it.
•Use equipment only for its intended purpose. Call your distributor for information.
•Route hoses and cables away from traffic areas, sharp edges, moving parts, and hot surfaces.
•Do not kink or over bend hoses or use hoses to pull equipment.
•Keep children and animals away from work area.
•Comply with all applicable safety regulations.

TOXIC FLUID OR FUMES HAZARD
Toxic fluids or fumes can cause serious injury or death if splashed in the eyes or on skin, inhaled, or
swallowed.
•Read Safety Data Sheets (SDSs) to know the specific hazards of the fluids you are using.
•Store hazardous fluid in approved containers, and dispose of it according to applicable guidelines.
PERSONAL PROTECTIVE EQUIPMENT
Wear appropriate protective equipment when in the work area to help prevent serious injury, including
eye injury, hearing loss, inhalation of toxic fumes, and burns. Protective equipment includes but is not
limited to:

Overview
3A9126A 7
Overview
This manual modifies the procedures in a King or
Contractor King sprayer manual. Follow all
modified procedures listed here, but consult the
primary sprayer manual for everything else.
The zinc circulation kit is designed to modify a King
or Contractor King sprayer, allowing the sprayer to
circulate viscous material containing zinc at a
continual rate while the spray gun is not in
operation. This helps prevent settlement of mixed
material while lessening the chance of clogging
and jamming within the sprayer and hoses.
A sprayer equipped with an installed zinc
circulation kit should not be operated at greater
than 4,500 psi, even if the sprayer is capable of
exceeding this pressure.
To avoid injury from component rupture when
using a sprayer equipped with a zinc circulation
kit, do not operate sprayer at greater than 4,500
psi.
Pressure Relief Procedure
8 3A9126A
Pressure Relief Procedure
Follow the Pressure Relief Procedure whenever
you see this symbol.
1. Engage gun trigger lock.
2. Close bleed type master air valve (B).
3. Disengage gun trigger lock.
4. Hold a metal part of the gun firmly against a
grounded metal pail. Trigger the gun until pressure
is relieved.
NOTE: If fluid does not flow from gun, see Flush,
page 11.
5. Engage trigger lock.
This equipment stays pressurized until pressure is
manually relieved. To help prevent serious injury from
pressurized fluid, such as skin injection, splashing
fluid and moving parts, follow the Flush when you
stop spraying and before cleaning, checking, or
servicing equipment.
Pressure Relief Procedure
3A9126A 9
6. Drain fluid. To drain fluid, slowly open all fluid drain
valves, including fluid drain/purge valve (J), in
system into a waste pail. If there is a return tube,
open return line ball valve. Close valve after fluid is
drained.
7. If you suspect the spray tip or hose is clogged or
that pressure has not been fully relieved.
a. VERY SLOWLY loosen tip guard retaining nut
or hose end coupling to relieve pressure
gradually.
b. Loosen nut or coupling completely.
c. Clear hose or tip obstruction.
