Pump
Start Up
1. Verify reservoir is filled with lubricant and system
has been primed (see Prime System, 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.
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.
Low Level Switch
As grease is dispensed, the follower plate (22) travels
down the reservoir. When it gets close to the low level
switch
(lls)
the magnet (28) on the bottom of the fol

Shut Down
To shut down the system:
a. Close the bleed-type master air valve (F, page
6).
b. Turn off electrical supply to the lubrication con
