Pressure Relief Procedure

Operation

Clearing Obstructions

The system pressure must be manually relieved to pre- vent the system from starting accidentally, which could cause moving parts to pinch or amputate your fingers. To reduce the risk for injury, always follow this proce- dure whenever you:

•are instructed to relieve the pressure

•check or service any part of the pump or system.

1.Shut off main air supply.

2.Close the air regulator and bleed-type master air valve.

3.Loosen a fluid fitting near the pump outlet to relieve fluid pressure.

KEEP YOUR FINGERS AND HANDS AWAY FROM THE PRIMING PISTON! The priming piston, located at the pump intake, could pinch or amputate your fin- gers as it moves into the intake cylinder.

1.Always relieve pressure, page 5, before attempting to clear any obstructions.

2.Disconnect Air Hose. Grip 1-3/4 inch hex in the cen- ter of the piston to unscrew it.

Startup

Reference numbers and letters in parentheses in the text refer to the callouts in the FIG. 2.

1.Turn on the main air supply.

2.Open Air Valve (E) and slowly open the Air Regula- tor (B) until the pump is running smoothly. Always use the lowest pressure necessary to deliver lubri- cant at the desired quantity.

CAUTION

Do not let the pump run dry. A dry pump quickly speeds up and may damage itself. If the pump is run- ning erratically or speeds up suddenly, relieve pump pressure following Pressure Relief Procedure (page 5) and change the lubricant drum. Use an Air Runaway Valve (D) to shut off the pump automatically when the drum is empty.

3.Shut off the pump and relieve pressure, page 5, when the pump is not in use.
