MPFHVLP SPRAY GUN

Setup

•Set shop air pressure regulator (not supplied) according to paint manufacturer’s recommendation. See maximum air and fluid pressures on cover.

•Make sure no air restrictions, such as low-volume cheater- valves, obstruct the air flow. If an air adjusting valve is desired, use a SHARPE Air Adjusting Valve 24AAV (part no. 2210), 36AAV-HOV (part no. 3310) or HOV (part no. U04410).

•Install a shutoff valve (not supplied) downstream of the air regulator to shut off gun air.

•Install an inline air filter (not supplied) to clean and dry the air supply to the gun.

1.Turn off air and fluid supply.

2.Connect a clean, dry, filtered air supply to gun air inlet (2).

3.Connect fluid supply line to gun fluid inlet (A).

4.If this is first time using the equipment, flush the spray gun.

Flushing

WARNING

Read warnings, page 2.

Flush before using the equipment, before changing colors, and when you are done spraying. Use solvent that is compatible with gun wetted parts and fluid that will be sprayed. Flush at lowest possible pressure.

Refer to Compliant Cleaning Methods, page 4, to com- ply with air quality laws if applicable.

1.Follow Pressure Relief Procedure.

2.Connect solvent supply to gun fluid inlet.

3.Spray into grounded metal waste container until equipment is clean.

4.Follow Pressure Relief Procedure.

Operation

Pressure Relief Procedure

WARNING

Follow Pressure Relief Procedure when you stop spraying and before cleaning, checking, or servicing equipment. Read warnings, page 2.

1.Turn off gun air and fluid supply.

2.Trigger the gun to relieve pressure.

Spraying

CAUTION

Excessive atomizing air pressure can increase over-spray, reduce transfer efficiency, result in a poor quality finish from dry spray.

Regulatory agencies in certain states prohibit the operation of a spray gun above 10 psi (69 kPa, .7 bar) atomizing air cap pressure.

1.Slowly adjust gun air pressure while fully triggering the gun until you have the desired atomization.

2.Adjust the pattern size and shape with the spray width adjustment knob (11). Turn knob clockwise to reduce pattern size and counterclockwise to increase it.

See Troubleshooting guide if you experience an irregular pattern.

3.Fluid control knob (7) is factory set for maximum needle trig- ger travel and material flow. To decrease needle/trigger travel and decrease fluid flow, turn knob clockwise.
