INJECTION HAZARD
Spray from the gun, leaks or ruptured components can inject fluid into your body and cause ex -
tremely serious injury , including the need for amputation. Fluid splashed in the eyes or on the skin
can also cause serious injury .
 Fluid injected into the skin might look like just a cut, but it is a serious injury . Get immediate
medical attention.

Do not point the gun at anyone or at any part of the body .

Do not put your hand or fingers over the spray tip.
 Do not stop or deflect leaks with your hand, body , glove or rag.
 Do not “blow back” fluid; this is not an air spray system.
 Always have the tip guard and the trigger guard on the gun when spraying.
 Check the gun dif fuser operation weekly . Refer to the gun manual.
 Be sure the gun trigger safety operates before spraying.
 Lock the gun trigger safety when you stop spraying.
 Follow the Pressure Relief Procedure on page 5 if the spray tip clogs and before cleaning,
checking or servicing the equipment.
T ighten all fluid connections before operating the equipment.
 Check the hoses, tubes, and couplings daily . Replace worn or damaged parts immediately . Do
not repair high pressure couplings; you must replace the entire hose.
 Fluid hoses must have spring guards on both ends, to help protect them from rupture caused by
kinks or bends near the couplings.
WARNING
WARNING
TOXIC FLUID HAZARD
Hazardous fluid or toxic fumes can cause serious injury or death if splashed in the eyes or on the
skin, inhaled, or swallowed.
 Know the specific hazards of the fluid you are using.
 Store hazardous fluid in an approved container . Dispose of hazardous fluid according to all local,
state and national guidelines.
 Always wear protective eyewear , gloves, clothing and respirator as recommended by the fluid
and solvent manufacturer .

FIRE AND EXPLOSION HAZARD
Improper grounding, poor ventilation, open flames or sparks can cause a hazardous condition and
result in a fire or explosion and serious injury
.

Ground the equipment and the object being sprayed. Refer to Grounding on page 5.
 If there is any static sparking or you feel an electric shock while using this equipment, stop
spraying immediately . Do not use the equipment until you identify and correct the problem.
 Provide fresh air ventilation to avoid the buildup of flammable fumes from solvents or the fluid
being sprayed.
 Keep the spray area free of debris, including solvent, rags, and gasoline.

Installation
Grounding
T o reduce the risk of static sparking, ground the pump
and all other spray equipment used or located in the
spray area. Check your local electrical code for de -
tailed grounding instructions for your area and type of
equipment. Be sure to ground all of this spray equip -
ment.
1.
Pump: use a ground wire and clamp (Fig 1).
2. Air hoses: use only electrically conductive air
hoses.
3.
Fluid hoses: use only electrically conductive fluid
hoses.
4.
Air compressor: follow manufacturer ’ s recommen -
dations.
5.
Spray gun or dispensing valve: grounding is ob -
tained through connection to a properly grounded
fluid hose and pump.
6. Object being sprayed: according to your local
code.
7.
Fluid supply container: according to your local
code.
8.
All solvent pails used when flushing , according to
local code. Use only metal pails , which are con -
ductive, placed on a grounded surface. Do not
place the pail on a non-conductive surface such as
paper or cardboard, which interrupts the grounding
continuity.

INJECTION HAZARD
The system pressure must be manually
relieved to prevent the system from
starting or spraying accidentally . Fluid
under high pressure can be injected through the
skin and cause serious injury . T o reduce the risk of
an injury from injection, splashing fluid, or moving
parts, follow the Pressure Relief Procedure
whenever you:
 are instructed to relieve the pressure,
 stop spraying,
 check or service any of the system equipment,
 or install or clean the spray tip.
WARNING
Pressure Relief Procedure
1. Engage the spray gun or dispensing valve safety
latch.
2. T urn of f the air to the motor .
3. Close the bleed-type master air valve (required).
4. Disengage the safety latch. Hold a metal part of
the gun or valve firmly to a grounded metal pail.
T rigger the gun or valve to relieve pressure.
5. Engage the safety latch.
6. Open the pressure drain valve. Leave the pressure
drain valve open until you are ready to spray
again.
If you suspect that the spray tip or hose is completely
clogged, or that pressure has not been fully relieved
after following the steps above , VER Y SLOWL Y loos -
en the tip guard retaining nut or hose end coupling to
relieve pressure gradually , then loosen completely .
Now clear the tip or hose obstruction.
Flushing
Before flushing, be sure the entire system and flushing
pails are properly grounded. Refer to Grounding , at
the left. Follow the preceding Pressure Relief Proce -
dure
and 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 flush -
ing.
