• Know and follow all safety precautions when handling petroleum fuels.
• Ensure that all equipment operators have access to adequate instructions
concerning safe operating and maintenance procedures.
Observe all safety precautions concerning safe handling of petroleum fuels.
To ensure safe operation, all remote dispensing systems must
be properly grounded. Proper grounding means a continuous
metal-to-metal contact from one component to the next, including tank, bung, pump,
dispenser, filter, hose and nozzle. Care should be taken to ensure proper grounding
during initial installation and after any service or repair procedures.
To prevent physical injury or property damage, observe
precautions against fire or explosion when dispensing fuel. Do
not operate the system in the presence of any source of ignition including running or

device. A spark can ignite fuel vapors.
Observe precautions against electrical shock when operating the
system. Serious or fatal
shock can result from operating electrical equipment in damp
or wet locations.
Observe precautions against electrical shock when servicing the
pump. Always disconnect power before repairing or servicing.
Never apply electrical power
to the system when any of the coverplates are removed.
Avoid prolonged skin contact with petroleum fuels. Use
protective goggles, gloves and aprons in case of splashing or
spills. Change saturated clothing and wash skin promptly with soap and water.
This dispenser is designed for use only with thin viscosity
petroleum fuels such as diesel and kerosene. Do not use this
dispenser for dispensing any other fluids other than those for which it was designed.
To do so may damage system components and will void the warranty.
This pump shall not be used for pumping fuel
or other liquids into aircraft.
An upstream, in-line mesh strainer must always be installed
when operating this meter; otherwise, particles may enter the
meter chamber and disrupt the smooth operation of the oval gears.

does not register the quantity on the container, adjust the meter by
performing the following:
a. Remove cabinet top cover. Gain access to the recessed calibration screw
by removing the 4 screws and calibration screw cover on back of meter (see
Figure 12).
b. Using the 5 mm hex L-wrench (provided) with the meter, adjust the
calibration screw as required.
NOTE: The calibration screw setting may have been adjusted at the factory. The
gasoline setting is approximately fully closed (turn clockwise). Do not overtighten
the screw against the seat.
c. If the meter registered less than the quantity in the container, turn the
calibration screw clockwise. If the meter display reads more than the
amount in the container, turn the calibration screw counterclockwise.
Empty the calibration container and repeat steps 2 to 4 until the meter
registers the quantity in the container.
Reinstall the plate, (4) screws and the O-ring seal if removed. Tighten (4)
screws to 42-46 lb-in (4.75-5.20 Nm) torque. Replace cabinet top.
