DESCRIPTION
The chassis lube pump is electrically operated and used in a
progressive type centralized lubrication system. The pump
consists of a pump housing, electric gear motor, a timer and
a plastic reservoir with stirring paddle. The high operating
pressure allows the pump to supply lubricant up to NLGI #2
grease. NOTE: Pump element especially designed for
Hammer Paste Lubricant.
MOUNTING THE PUMP
Select an easily accessible place of installation which
allows access to the timer and lubricant reservoir filler fitting.
The pump must be mounted vertically on an even surface by
means of three bolts.
TO FILL RESERVOIR
Fill the reservoir through the grease fitting located at the
base of the reservoir, using a hand operated grease pump.
Refill reservoir when grease reaches MIN mark located on
the reservoir. Fill the reservoir up to the MAX mark located
on the reservoir.
TO PRIME SYSTEM
Pump & Supply Line: After reservoir has been filled with
recommended lubricant, loosen the supply line fitting.
Operate the pump until lubricant flows from outlet, then
tighten fitting.
Feed Lines: Pre-fill each feed line with lubricant before
connecting to outlet of divider valve and bearing.

Manual Lube Kit is required.
The wiring for the remote light
used on the 103 pump must
be changed for the new Model

TIMER OPERATION
The "Off" timer begins accumulating time when the ignition
switch closes. When the "Off" timer reaches the preset
value, the pump will turn on. The pump remains activated
for the period of time that is preset on the "On" timer.
When the ignition switch opens, the "Off" timer will retain its
accumulated time for a period of five days. When the ignition
switch closes during the five day period, the "Off" timer will
resume timing from the accumulated time it reached prior to
the ignition switch opening. If ignition switch is not closed
before the end of five day period, timer will begin with an "On"
period.
Remove Sealing Plug (item 22) to access manual lube
switch or to view the system LEDs.
1. The LED marked "battery" lights when power is applied to
the PC board.
2. The LED marked "motor" lights when pumping lubricant.
3. Depressing pushbutton for 2 seconds will initiate a manual
lube event.
4. "Off" time rotary switch, factory set to 3.75 minutes.
5. "On" time rotary switch, factory set to 30 minutes.
NOTE: Do not change settings of "Off" or "On" time rotary
switches.
