Operation – Electronic Meter
Never operate the meter with the black plastic
cover removed. The cover protects the meter from
damage due to impact. Meters are factory sealed
to keep moisture and dirt out. See the Service
section before you service the meter.
CAUTION
To prevent line contamination, which can cause
equipment malfunction or damage, flush the lines
before you install this equipment in the system.
CAUTION
To Activate the Digital Display
Press the RESET key pad to clear the meter before
you start a new dispense cycle. This is the best way
to activate the meter, because it also clears the
quantity of the last dispense cycle.
The digital display can also be activated by pressing
the TOTAL key pad or by running fluid through the me-
ter. See Fig. 1.
NOTE: The digital display of the meter goes blank
after approximately two minutes of non-use.
Function of TOTAL
When the digital display is blank, press and release the
TOTAL key pad to display the quantity of the last dis-
pense cycle. See Fig. 2.
To see the accumulated total of fluid dispensed
through the meter, press and hold the TOTAL key pad.
The accumulated total is shown in gallons for the
gallon/quart/pint meter, and in liters for liter meter. The
meter can accumulate a running total of up to 19999
gallons (or liters) dispensed before returning to zero.
See Fig. 3.
Function of RESET
Press the RESET key pad to clear the quantity of the
last dispense cycle and return the digital display to all
zeros. See Fig. 1.
To Change the Measurement Units
(gallon/quart/pint meter only)
The meter is factory-set to dispense in quarts. To
change the measurement units, press and hold the
RESET key pad until the measurement unit on the
right side of the digital display is flashing. Then press
the TOTAL key pad until the desired measurement unit
is shown. Release both key pads. See Fig. 4.
To be sure the proper amount of fluid is dispensed,
always use the same measurement unit for a par-
ticular fluid.Units should be changed only by autho-
rized employees.
CAUTION
For Maximum Dispensing Accuracy
(gallon/quart/pint meter only)
Set the meter to dispense in pints or quarts when dis-
pensing 1 gallon or less.
Always press the RESET key pad to clear the meter
before a new dispense cycle.

WARNING
To reduce the risk of fluid injection, always grasp
the nozzle housing (B) from the threaded end, not
from the front, when you adjust the nozzle.
To prevent line contamination, which can cause
equipment malfunction or damage, flush the lines
before you install this equipment in the system.
CAUTION
If you are not using a Hi-Flow nozzle, remove the cap
(A) from the tube. See Fig. 5.
To dispense from the Hi-Flow nozzle (B), turn the
knurled sleeve clockwise until it is open. Trigger the
valve. See Fig. 5.
When the dispense cycle is completed, release the
trigger, and close the nozzle by screwing the knurled
sleeve fully counterclockwise. See Fig. 5.
For electronic metered valves, press the RESET key
pad on the meter to clear it before the next dispense
cycle. See Fig. 1.
Trigger the dispense valve. Lubricant begins to flow
with the slightest movement of the trigger and contin-
ues to flow until the trigger is released.
When you dispense lightweight fluids, such as auto-
matic transmission fluid, increase the free play of the
dispense valve trigger. This reduces the flow and re-
duces splashing of the fluid. To adjust the trigger free
play, loosen the adjusting screw locknut (C). Back the
screw (D) out until the desired flow is achieved, then
tighten the locknut securely. See Fig. 6.
To lock the control valve in the open position, engage
the trigger latching pin in the latch (E). See Fig. 6. To
release the latch, squeeze and release the trigger.
