Operation

Pressure Relief Procedure

Follow the Pressure Relief Procedure whenever
you see this symbol.
This equipment stays pressurized until pressure is
manually relieved. To help prevent serious injury from
pressurized fluid, such as skin injection, splashing
fluid and moving parts, follow the Pressure Relief
Procedure when you stop dispensing and before
cleaning, checking, or servicing the equipment.
1. Close the bleed-type master air valve (F, F
page 6) (required in the system).
2. Relieve pressure in system using two wrenches
working in opposite directions on the pump outlet
(E) and lubrication line fitting (G) to slowly loosen
the fitting until it is loose and no more lubricant or
air is leaking out of the fitting (F

Pump

Start Up

1. Verify reservoir is filled with lubricant and system
has been primed (see Prime, page 9).
2. Turn on the lubrication controller (J) power switch.
3. Program the lubrication controller to actuate the
solenoid valve (C).
NOTE: See the lubrication controller instruction
manual included with the system for these instruc-
tions.
4. Open air regulators and master air valves.
NOTE: Never allow the pump to run dry of the material
being the pumped.
NOTICE
Running the pump dry will cause an air lock. To pre-
vent an air lock, do not run the pump without lubricant.
Always refill the pump before it is empty.
At the start of a the pump cycle:
a. The air solenoid (C) supplies air to the pump air
inlet (P).
b. On the pump forward stroke, lubricant is dis-
pensed to all the injectors.
c. The pump is supplied with air through the air
inlet (R).
d. The pump makes a return stroke, venting the
system pressure back to the pump and reset-
ting all of the injector.
