Normal operation for liquid cooled pumps:
1. Check oil reservoir daily and fill as required.
2. When the pump is in operation, check the oiler to
insure flow of oil to the pump.
3. Do not operate the pump faster than recommended
rpm.
4. If an in-line 12 volt circulating pump is used,
make sure it is turned on.
5. Always monitor the water temperature gauge.
6. To operate the suction valve on top of the pump,
move the handle in the appropriate direction for
either vacuum or pressure. Center it for neutral.
7. We recommend periodic cleaning of your pump.
To do this, remove the suction line from the pump.
Move the suction valve to neutral, run the pump at
an idle, and pour into the pump intake one pint of
diesel fuel. Allow the pump to run a short time,
move the suction valve to vacuum, and blow our
the diesel fuel and dirt. Move the suction valve to
neutral and pour in a pint of oil. Allow the pump to
run a short time before reassembling.
8. We recommend checking vane wear every twelve
months. A new vane is nearly flush with the rotor.
Measure the wear and if is over 1/4" we
recommend
recommend replacing vanes. It’s good to always keep
a spare set of vanes on hand for emergencies.
