Operation
Pressure Relief Procedure
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.
Startup
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.
3. Shut off the pump and relieve pressure, page 5,
when the pump is not in use.
Clearing Obstructions
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.
Removing Inductor Plate from Drum
FIG. 3
1. Relieve pressure, page 5.
2. Lift pump off inductor plate.
3. Insert the release bar (15) into the neck of the plate
and position it so that by applying leverage, the vac-
uum seal which formed beneath the plate, is broken.
4. Remove the plate.
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.

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.
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.
