MicroFlex Spray Gun

DO NOT OPERATE SPRAY GUNS WITHOUT PERSONAL SAFETY EQUIPMENT





The AirVerter

®


TM

Spray Gun is a precision instrument. It requires meticulous care and maintenance to achieve its outstanding results.

The MicroFlex uses "micro" fittings and tiny air and fluid passages to spray small amounts of material. Consequently, the MicroFlex must be faithfully cleaned and maintained.

The MicroFlex requires extremely little fluid and air pressure and requires precise adjustment.

These adjustments, while not able to be adequately described in this manual, are second nature to trained technicians.

Smith Eastern Corporation warrants to the Purchaser that the AirVerter

®


TM

MF-3100 Spray Gun is free from defects in material or workmanship under normal use and service for a period of twelve (12) months from the date of purchase.

Should any failure appear during this period, Smith Eastern shall, if given prompt written notice by the Purchaser, correct such nonconformity by repair or replacement of the nonconforming part, F.O.B. Smith Eastern’s repair facility. Repair parts are warranted for ninety (90) days from the date of shipment, but repairs or replacements to original equipment shall not renew or extend the warranty period of such equipment.

Equipment and parts furnished by Smith Eastern but manufactured by others shall be limited to the warranty offered by the manufacturer thereof. Smith Eastern reserves the right to limit this warranty in cases of misuse or abuse. Any modifications to spray guns or recommended procedures will void the warranty.

The foregoing warranty is exclusive and in lieu of other warranties of quality or performance, expressed, implied or statutory, including any warranties of merchantability or of fitness for a particular purpose.

DO NOT OPERATE AIRVERTER SPRAY GUNS WITHOUT USING PROPER

PERSONAL SAFETY EQUIPMENT INCLUDING RESPIRATOR, GOGGLES

AND SAFETY CLOTHING.

OBSERVE ALL PRECAUTIONS RELATED TO SPRAYING.

THIS EQUIPMENT IS OPERATED USING PRESSURIZED AIR. ALWAYS

DISCONNECT SPRAY GUN FROM AIR AND FLUID HOSES AND

DEPRESSURIZE SYSTEM PRIOR TO DISASSEMBLY OR MAINTENANCE.






1. Air Compressor that will hold a minimum of

20 PSI at the gun. Important: Position a pressure gauge at the end of your air hose next to the gun to be assured of the PSI required to satisfactorily spray your coating.

2. High Pressure Air Hose: a. Air hose lengths up to 50 feet

MUST have an I.D. of 3/8 inch.

b. Air hose lengths greater than 50 feet MUST have an I.D. of 1/2 inch.

3. Pressure Pot or Diaphragm Pump - Be certain to follow manufacturer's instructions to ensure proper use.

Using A Remote Pressure Pot or Diaphragm Pump

1. Attach the fluid hose from your pressure pot to the Fluid Fitting (DT-3113).

2. Attach the air source to the base of the

Metering Valve (AV-175).

.

1. Before you use your paint, make certain it is properly mixed. This is particularly true of multi-component paints. Use a paint shaker, rotary mixer, or paint paddle to achieve a homogeneous mixture. We recommend splitting your paint into two parts; the top will typically be lighter and the bottom will be heavier. Completely stir the bottom half of the paint and slowly add small amounts of the top half into the heavier bottom.

2. Strain your paint to remove impurities. Use a cone strainer, or a 100-mesh nylon bag or equivalent strainer.

3. Thin your paint according to the manufacturer’s specifications.

4. Needle packings (BCR-043) are preset at the factory and self adjusting. Replace packing cartridge when necessary.

1. Air pressure forces paint from the paint container into the fluid chamber of the gun and out through the nozzle where the flow of air breaks the paint stream into tiny particles (atomization), creating the spray.

a. Needle position controls the amount of paint flowing through the fluid nozzle.

b. Trigger action controls needle position.

c. The Fluid Control Knob (DT-3012) at the rear of the spray gun controls trigger action. Turning to the right will reduce fluid flow; turning to the left increases flow.

2. Regulate the air entering the gun by using the Metering Valve (AV-175). Adjust the air until you have the desired atomization. Too much air or fluid pressure will cause the gun to spray improperly and will create unnecessary overspray! You need only a small amount of air as you are atomizing only a small amount of paint.

3. Align the Flexible Extension (MF-008) to the desired position.

4. If you are having problems with the operation of your paint gun, check the

Trouble Shooting Guide at the end of the manual for possible causes and solutions.

Spray gun performance is directly related to how well it is cleaned after each use.

This is particularly true for the small orifices in the MicroFlex.

WARNING!

Always de-pressurize system prior to any maintenance or disassembly procedure.

Disconnect all air and fluid hoses prior to performing any maintenance operation.

1. Run or pump solvent through the gun to completely remove paint from the fluid chamber. Flush passages thoroughly, as brushes or other devices will not reach most parts of the fluid chamber. Note: The

Fluid Hose provided is not designed for repeated detachment and reattachment to the Hose Barb or Spray Head. If flushing with solvent cannot clear a clogged Fluid

Hose, replace the Fluid Hose.

2. Unscrew the Connector Stud (using knob

DT-014) to detach the Spray Head

Assembly from the Handle (DT-3300) and set the Spray Head Assembly aside.

3. Wipe the Handle and Needle (DT-3007) clean with solvent and a clean soft cloth.

Use caution to avoid damaging or bending the needle. Re-lubricate the needle with

Vaseline.

4. Unscrew the Pattern Control Ring (AV-101) from the Spray Head Assembly to separate the Adapter Collar (MF-002) from the Spray

Head Assembly exposing the Fluid Hose

(MF-010).

5. With the wrench provided, remove the

Needle Seat (MF-3006) from the Spray

Head Assembly. Use caution to avoid damaging or bending the Hose Barb (MF-

012). Be careful not to lose the Anti-

Friction Washers (MF-003).

6. Unscrew the Hose Barb from the Needle

Seat. Clean the Needle Seat with brush provided.

7. Unscrew the MicroFlex Air Cap (MF-202 or

MF-203) and clean with solvent ensuring all passages are absolutely clean.

8. Unscrew the MicroFlex Spray Head (MF-

200) from the Flexible Extension (MF-008).

9. Clean the MicroFlex Spray Head (MF-200) with solvent ensuring all passages are clean and free of obstructions. Use caution to avoid damaging or bending the fluid nozzle tip.

10. Use the round brush supplied to clean

Needle Packings (BCR-043).

11. Inspect to make certain that all paint residue has been removed from the fluid chambers in the Spray Head Assembly.

12. Wipe all parts dry with a clean cloth before reassembling.

Important! If using a gun washer, remove the needle from the handle and insert into the Needle Packings. This ensures solvent will pass through the Fluid Hose.






1. Screw the Spray Head into the Flexible

Extension and attach the Air Cap to the

Spray Head.

2. Attach the Fluid Hose and Hose Barb to the

Needle Seat.

3. Remember to place the larger of the two

Anti-Friction Washers between the Spray

Head (DT-3403) and the Adapter Collar

(MF-002)

4. Reattach the Needle Seat to the Spray

Head.

5. Replace the MicroFlex Adapter Collar,

Rigid Extension, Flexible Extension, Anti-

Friction Washers and Pattern Control Ring on the Spray Head Assembly observing that the Fluid Hose inside the Adapter

Collar is not kinked.

6. Carefully align the spray head and handle and insert the needle into the Packing Nut.

7. Tighten the connector stud.






1. Clean all paint residue from the pressure pot or pump.

2. All fluid passages must be clean and free of obstructions.

3. All gauges and valves must be clean and in proper working order.

1. Use Vaseline or a non-silicone grease to lubricate the gun.

2. Lubricate all threaded connections for ease of maintenance.

3. Lubricate the needle where it passes through the needle packing.

4. DO NOT allow lubricant to get into areas where paint may come into contact with lubricant.
