Safety Information & Warnings
Before operating The MG Spray Gun, personnel should fully
understand the contents, recommendations, and safety notes
contained in this manual.
Failure to follow these guidelines may result in severe bodily injury
or damage to equipment and property.
The safety guidelines outlined in this manual are not intended to be
all inclusive. A certain degree of knowledge of general industrial
safety practices as used in the spray applied coatings and foam
industry are required to insure operator safety.
Aluminum Parts Hazard
Do Not Use 1,1,1-Trichloroethane, Methylene Chloride, or other
halogenated hydrocarbon solvents, or fluids containing these
solvents in the MG Gun. These solvents are capable of causing a
serious chemical reaction, and possible rupture when used in
pressurized aluminum equipment.
Personal Protection
The operator and personnel in the vicinity of this equipment must
ensure their personal safety by wearing:
Protective eyewear
Protective clothing and gloves
Protective breathing apparatus, supplied fresh air system, or
approved respirator.
Injection Hazard:
This equipment operates at high fluid pressure and is capable of
injecting chemicals into skin.
Do not place hands or fingers in area of spray pattern.
Never point spray gun in the direction of other personnel.
Close material supply valves before leaving spray gun
unattended.
Relieve all pressure before servicing or cleaning this
equipment. If chemicals have pierced skin, get immediate
medical attention.
Chemical Materials and Fumes: Read and understand Material
Safety Data Sheet (MSDS) provided by chemical manufacturer.

GENERAL OPERATION OVERVIEW
GUN SAFETY DEVICES:
The MG Gun has two methods of putting the gun in the safe mode.
# 1. Air Valve:
Gun will not trigger without air pressure to the air cylinder.
To engage air valve safety, turn air valve handle clockwise.
Air needle valve will vent air contained in gun handle and air
cylinder.
# 2. Material Shut Off Valves:
Gun will not dispense material with A & B manual valves
closed.
To engage manual valve safety, turn manual valves
clockwise until closed.
Hose Orientation:
With gun pointing away from operator, Acomponent hose and
manual valve is on operators left. Bcomponent hose and manual
valve is on operator’s right.
Air Hose Connection:
Insure that air valve at rear of air Cylinder is in the closed/safe
position.
Air hose is connected by inserting male quick disconnect fitting
located at end of air whip hose into female quick disconnect air
fitting located in heated hose bundle. When gun is not in use, keep
air fitting free of debris.
Coupling Block:
The A & B material whip hoses are connected to the gun head by
the coupling block bolt.
Insure that the two coupling block o-rings are in place.
Material Shut Off Valves:
The A & B manual valves control the on/off flow of material to the
gun. Open valves 2 turns when spraying.
Do not open manual valve unless the gun is connected, or the
coupling block material ports are directed into a suitable container.

Important Tips for Operation
Air cap and mating front face of gun must be very clean and free of
nicks.
Air cap bolts must be greased and tightened with wrench until tight.
Consult your material supplier for the proper cleaning and flushing
solvent to use.
Ensure that cleaning solvents do not cause swelling of o-rings.
Do not soak o-rings or mix module in solvent. Solvent may be used
for cleaning, and then dried off.
Air cap clean off air should remain on whenever manual valves are
open.
Do not submerge entire gun in cleaning solvent. O-Ring damage
will result.
Lubricate air line inlet daily, 2-3 drops of air tool oil only.
Apply light coat of grease or wax to exterior of gun daily to prevent
overspray build up.

Initial Gun Start Up
Install Coupling block / Whip hose assembly to heated hose set:
1. Attach Coupling block / whip hose assembly to existing hose
assembly using either adapter fittings, or adapter blocks. See page
8. Check to see that A & B material shut off valves are closed.
2. Turn on hose heat and machine heaters. Set temperature, and
allow machine to reach spray temperature.
3. Pressurize equipment, bleed air from coupling block/ whip hose
assembly into suitable waste container. Equalize A and B
component pressure gauges at correct spray pressure.
Assemble MG spray gun:
1. Check to see that basket filters and coupling block o-rings are in
place.
2. Apply light coat of grease or wax to gun to prevent overspray from
sticking.
3. Attach gun to coupling block using 5/16” nut driver.
4. Plug in air supply whip hose, open air / safety valve at rear of gun.
5. Open pattern air valve ¼ - ½ turn.
6. Slowly open A & B material shutoff valves 1 ½ turns. Check for
material mist in pattern or leakage at air cap.
Gun is now ready to spray. Aim off target, spray off target until good
pattern develops.
