Operation

Daily Startup

1.Verify that the air needle valve (54) is closed.

2.Connect the air line quick disconnect cou- pler (55) to the transfer pump.

3.Turn on the main air supply.

4.Slowly open the air needle valve until the transfer pump runs slowly.

5.Use the air needle valve to control the pump speed.

Caution

Never allow the pump to run dry. A dry pump will quickly accelerate to a high speed and can damage the pump. If the pump acceler- ates quickly or starts running too fast, stop it immediately and check the fluid supply. If the supply container is empty or air has been pumped into the lines, refill the container; prime the pump and the lines with fluid, or flush and leave it filled with a compatible sol- vent. Be sure to eliminate all air from the fluid system.

Do not attempt to operate pump unless it is securely mounted in a drum.

Daily Shutdown

1.Disconnect the air line quick disconnect coupler (55).

2.When air pressure is bled off, close the air needle valve (54).

Corrosion Protection for Pump

Caution

Water or moist air can cause your pump to corrode. To help prevent corrosion, NEVER leave the pump filled with water or air. After normal flushing, flush the pump again with mineral spirits solvent (also called white spirit) or oil-based solvent, relieve pressure, and leave the mineral spirits solvent (also

called white spirit) in the pump. Be sure to follow to the Pressure Relief Procedure on

page 13.

Lubrication

If you are not using an accessory air line lubri- cator, manually lubricate the motor daily. Dis- connect the air regulator, place about 15 drops of light machine oil in the pump air inlet, recon- nect the regulator and turn on the air supply to dispense oil into the motor.
