Operating Instructions for Undercoating/Rustproofing Pro Gun

(Model: UCpro and UCPro Plus)

Professional Undercoating and Rustproofing gun designed to apply protective coatings such as waterborne and

solvent based under coatings, noise dampening coatings ,thermal insulation, bed liners, rust prevention oils ,

underneath cars , trucks , trailers , RV’s, buses etc. and to spray wax based cavity coatings inside doors, beams,

rocker panels and other cavities. This gun allows for pressure to build up inside the tank. This pressure will assure that

the cavity coating will be atomized at the tip of the wand and provide total coverage of the rustproofing inside the cavity.

This allmetal gun was built for industrial use by body shops, car dealers and undercoating professionals.

•Die cast aluminum body

•Aluminum tank

•Stainless steel needle

•Tank capacity: 1 liter

•Air consumption: 7-10 CMF

•Working pressure: 60-90 psi

1. Spraying heavier coatings:

This gun builds up airpressure inside the tank. That allows for the application of thicker coatings i.e.

undercoatings, bed liners, sound dampening, rust proofing,fire retardants, etc.

You can apply these coatings directly out of the gun with the spray cap (FIG.1 #5)and spray head

(FIG.1 #6) installed. Different textures can be obtained by changing the airpressure, product flow

(FIG.1 #3)and/or air atomizer (FIG.1 #2)settings.

In general, air pressure to the gun should be around 60 psi.

Optimal airpressure level will differ depending on the viscosity of the product to be sprayed. Keep in mind

that the viscosity might fluctuate depending on the ambient temperature.

As you open the product control knob (FIG.1 #3), the application will become more and more textured.

An optional wand (item BS-39) isavailable to spray heavier coatings in hard to reach places i.e. around

mufflers and behind exhaust pipes. This wand isNOT supplied with the gun model UCPro but isincluded

with model UCPro Plus. To install this wand, unscrew the spray cap (FIG.1 #5)and screw the wand onto

the spray head (FIG.1 #6).

NOTE:

1) The wands supplied with this gun (FIG.1 #10 AND #11)are rust proofing wands developed for the

application of thinner coatings i.e. cavity wax and rust fighting oils. The inside diameter of these

wands is too small to spray heavy coatings. Only use the Undercoating wand BS-39 for this purpose.

2) Some bed liners are mixed with rubber pellets or silica crystals to make the coating more slip

resistant. These coating cannot be applied with this gun.

2. SprayingRust Proofing:

To spray Rust proofing such as Cavity Coating and rust fighting oils, remove the spray cap (FIG.1 #5)

and connect the Quick Coupling Connector (FIG.1 #9)supplied with the gun.

To spray directly out of the gun, install the rust proofing spray tip (FIG.1 #8).

Remove this spray tip by pushing the release ring on the Quick Connector backwards and holding your

hand in front of the spray tip. Connect the wands by pushing the male fitting into the Quick Connector.

Wand Cleaning:

Upon finishing the rust proofing task, purge left over product from the wands by pulling the trigger

halfway. Rinse wand with solvent /water to dissolve product left inside the wands. Always check the

MSDS and tech sheets supplied with the product sprayed to make sure you are using an appropriate

cleaner.

3. Setting the air regulator on top of the tank:

This gun was designed to apply both solvent based and water based coatings. When spraying solvent

based coatings make sure that the air regulator (FIG.1 #7)iscompletely closed. Depending on the brand

of waterborne product you are using, you might have some premature drying of the coating at the nozzle

of the gun. This could interrupt the spraying process. In this case, open the airregulator slightly to reduce

pressure in the tank.

When refilling the tank, use this regulator to release the pressure in the tank and make unscrewing

easier.

IMPORTANT!

When spraying cleaning solvents with the gun, ALWAYS close the Air Control Knob (FIG.1 #2)and the air

regulator (FIG.1 #7)first. Atomized solvents are extremely flammable. Properly dispose of cleaning

solvents as per local regulations.

4. WARNINGS

Please read carefully and follow the instructions listed in this section.

Before using the spray gun, read the operating instructions and follow them thoroughly.

Before carrying out any type of maintenance or repair operation, ask information from your retailer or from

a specifically trained technician otherwise your warranty will automatically be voided.

Always disconnect the spray gun from the air supply when stored or before starting any maintenance or

cleaning activity.

When selecting and before using the product to be sprayed with the gun, verify that it is in fact compatible

with the work environment and the individual safety devices employed, according to the product safety

sheet.

While operating the spray gun, wear the appropriate safety garments and devices (gloves, safety glasses,

masks, overalls, etc.) according to the instructions listed in the product safety sheet. The use of safety

protection glasses is always recommended.

Hang the gun on the special hook when it is not being used, so as to guarantee its vertical position. Never

tilt the spray gun at an angle greater than 45°, either while operating it or while not in use, in order to

avoid fouling of the spray gun’s ducts.

Keep the safety valve FIG.1 #7 clean and assure that itis not blocked.

DANGER OF FIRE OR EXPLOSION

Do not use solvents and/or halocarbon based detergents (1.1.1 Ethyl trichloride, Methylchloride, etc.)

since they could rust galvanized parts causing explosive chemical reactions.

Never use acidic or alkaline substances for cleaning (basics, paint-removers, etc.) Do not smoke or

produce sparks: this could cause

re.

Always be sure that the painting equipment is grounded correctly.

HEALTH SAFETY EQUIPMENT AND PRECAUTION

Use the spray gun only in well ventilated areas.

Always wear suitable protective gloves and goggles as well as specific breathing

lters/masks.

Use special clothing to protect the body from contact with toxic vapors, solvents or with the products in

use.

The use of paint products containing organic solvents can cause intoxication due to the toxic fumes

they emit. In every case, it is necessary to read the technical sheets for the products before use.

WARNINGS CONCERNING IMPROPER USE

After cleaning, maintenance and/or repairs and, in any case, before using the spray gun, make sure

nuts and bolts are

rmly secured in their housings.

Never direct the jet towards people or animals. Never exceed the rated air pressure (120 PSI).

Before disassembly and cleaning, make sure that the spray gun has been disconnected from the air

supply unit. Do not clean the parts with abrasive brushes or sand paper.

GENERAL RISK

The product must be not used if it has been subjected to potential damage following an impact or a fall

which may have compromised its resistance, in particular regarding endurance, adjustment or

pressure parts.

Negative effects may not be immediately visible in terms of fractures, cracks or other similar effects. If

any of the said events occur do not use the product, but have inspections and testing carried out on it

before putting it back in service.

If you have any doubts please contact the salesman before using the product.

Check periodically the wear and tear of the threads in order to avoid accidental detachment of parts

like for example the tank or the product’s adjusting knobs.

5. Operating the Spray Gun

The air supply should be equipped with a pressure regulator,

lter and shut off valve.

Always disconnect the air supply before storing, cleaning or doing any maintenance on the gun or

unscrewing the tank.

Secure the tank

rmly before connecting the gun to the air supply.

Release the air pressure from the tank before opening by opening the safety valve (FIG.1 #7).

Do not tilt more than 45°, use spray wands in difficult to reach areas.

At the end of application, disconnect the air supply andhang the spray gun on the special hook.

Depending on the products used, there may be danger of fire; avoid smoking and open flames while

spraying potentially flammable products.

Danger of ejection of the adjustment knobs: do not exceed the specified adjustment limits.(FIG.2&3)

6. Adjustments

Adjusting ofthe product flow (Fig. 2)

Turn product control knob (Fig.2 #3)clockwise to gradually

decrease the

ow of product. Turn counter-

clockwise to increase

product

ow.

During this adjustment, do not exceed the maximum extension

for the product control knob. The knob is spring loaded and will

eject when turned out too far.

Knob will travel 9mm between closed and completely open position.

Adjusting product atomization (Fig. 3)

Turning control knob (Fig.3 #2)clockwise will close the air passage

gradually and reduce atomization resulting in a rougher texture.

Turn control knob (Fig.3 #2)counterclockwise to open the air passage

gradually. This will increase atomization and result in a smoother

finish

Never close knob (Fig.3 #2)completely during applications.

During this adjustment, do not unscrew the control knob (Fig.3 #2)

pastthe black gasket. This knob is spring loaded and will eject if

unscrewed completely. Knob will travel 8mmbetween closed and

completely open position.

Combined Adjustment

Even rougher or smoother textures can be obtained by adjusting both

knobs at the same time. Less product and more atomization gives a

smoother

nish, more product and less atomization will produce a

more textured

nish.

7. Troubleshooting

8. Cleaning

1) Disconnect the spray gun from the air supply.

2) Empty out the product from the spray gun.

3) Pour into the tank the necessary amount of cleaner (usually ½ liter) suitable for cleaning the product

being used.

4) Close the tank and connect the spray gun again.

5) Spray the cleaner, directing the jet into a special container.

Make sure that the air-regulator (Fig.3 #2) is completely closed to avoid atomization of the

cleaner which may lead to pollution of the nearby environments.

Do not immerse the spray gun completely into the solvent, but rather clean it with a soft brush or

a cloth

9. Maintenance

1) In case the product leaks out around the needle packing, in front of the trigger (Fig.1 #4), clean the

fouled parts immediately.

2) Turn the packing screw clockwise to hermetically seal the packing. This will prevent the product from

leaking again. Make sure that the needle remains free to move.

3) Whenever necessary, lubricate the needle at the packing screw.

4) Occasionally, lubricate the air valve rod.

When the spraying job is finished or during a break, hang the spray gun on the special hook

5) Never use force. Using improper tools such as pipe wrench, gas torch, etc. will void any warranty. In

many cases proper repairs can only be carried out with the aid of special tools. In such cases, limit

yourself to establishing the cause of the problem and leave the repairs to the service department.

We will refuse to accept liability for faulty functioning spray gun if it is disassembled by the customer
