WARNING
INJECTION HAZARD
Spray from the gun, hose leaks, or ruptured components can inject fluid into your body and cause an
extremely serious injury, including the need for amputation. Splashing fluid in the eyes or on the skin
can also cause a serious injury.
DFluid injected into the skin might look like just a cut, but it is a serious injury. Get immediate medi-
cal attention.
DDo not point the gun at anyone or at any part of the body.
DDo not put your hand or fingers over the gun nozzle.
DDo not stop or deflect leaks with your hand, body, glove or rag.
DDo not “blow back” fluid; this is not an air spray system.
DBe sure the gun trigger safety operates before dispensing.
DLock the gun trigger safety when you stop dispensing.
DFollow the Pressure Relief Procedure on page 5 if the gun nozzle clogs and before cleaning,
checking or servicing the equipment.
DTighten all fluid connections before operating the equipment.
DCheck the hoses, tubes, and couplings daily. Replace worn, damaged, or loose parts immediately.
Permanently coupled hoses cannot be repaired; replace the entire hose.
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.
DKnow the specific hazards of the fluid you are using.
DStore hazardous fluid in an approved container. Dispose of hazardous fluid according to all local,
state and national guidelines.
DAlways wear protective eyewear, gloves, clothing and respirator as recommended by the fluid and
solvent manufacturer.

Installation
Grounding
WARNING
FIRE AND EXPLOSION HAZARD
Before operating the pump, ground the
system as explained below. Also read
the section FIRE AND EXPLOSION
HAZARD on page 3.
1. Pump: use a ground wire and clamp as shown in
your separate pump manual.
2. Fluid hoses: use only electrically conductive fluid
hoses with a maximum of 500 feet (150 m) com-
bined hose length to ensure grounding continuity.
Check the electrical resistance of your fluid hoses
at least once a week. If your hose does not have a
tag on it which specifies the maximum electrical
resistance, contact the hose supplier or manufac-
turer for the maximum resistance limits. If the hose
resistance exceeds the recommended limits,
replace it immediately.
3. Air compressors and hydraulic power supplies:
ground the equipment according to the manufac-
turer’s recommendations.
4. Flow gun: ground through connection to a properly
grounded fluid hose and pump.
5. Fluid supply container: Ground according to your
local code.
6. Flammable liquids in the dispensing area: must be
kept in approved, grounded containers. Do not
store more than the quantity needed for one shift.
7. Solvent pails used when flushing: follow your local
code. Use only metal pails, which are conductive,
placed on a grounded surface. Do not place the
pail on a nonconductive surface, such as paper or
cardboard, which interrupts the grounding continu-
ity.
8. To maintain grounding continuity when flushing or
relieving pressure, hold a metal part of the gun
firmly to the side of a grounded metal pail, then
trigger the gun.

Operation
Pressure Relief Procedure
WARNING
INJECTION HAZARD
The system pressure must be manually
relieved to prevent the system from
starting or dispensing accidentally. Fluid
under high pressure can be injected through the
skin and cause serious injury. To reduce the risk of
an injury from injection, splashing fluid, or moving
parts, follow the Pressure Relief Procedure
whenever you:
Dare instructed to relieve the pressure,
Dstop dispensing,
Dcheck or service any of the system equipment,
Dor install or clean the nozzle.
1. Fully release the gun trigger. Press the red button
to lock the trigger safety. See Fig. 1.
2. Shut off the fluid supply pump.
3. Hold a metal part of the gun firmly to the side of a
grounded metal pail. Press the silver button to
unlock the trigger safety. Trigger the gun to relieve
pressure.
4. Open the pump drain valve to help relieve pres-
sure in the pump, hose, and gun. Triggering the
gun to relieve pressure may not be sufficient. Have
a container ready to catch the drainage.
5. Leave the drain valve open until you are ready to
dispense again.
6. Fully release the gun trigger and lock the trigger
safety.

To dispense material, unlock the trigger safety, then
fully squeeze the trigger. Flow begins with the slightest
pressure and continues until the trigger is released.
NOTE: A minimum of 1 pint (0.5 liters) of material
must be dispensed from the gun to remove all air from
the system. If the air is not completely removed, slow
shutoff may occur.
Adjust the pump to the minimum speed necessary to
deliver the material at a satisfactory rate, or adjust the
fluid/mastic regulator.
Lubrication and Care
Keep the gun clean, and oil the exposed portion of the
needle with a light, high grade machine oil daily.
