TROUBLESHOOTING / MAINTENANCE
If there is no pressure indication in the Master / Test
Instrument even after considerable pumping action of the
handle, check the following:
Ensure that the connections between the pump, the
hose end and the Test / Master Instrument(s) are
tight and then retry pumping.
Check that the Release Valve is closed.
Check whether the Pressure / Vacuum selector is left
half way in between pressure side & vacuum side. If
so, push it firmly in place (either vacuum or pressure
side) as needed.
Chances are there that one of the seals in the PHP is leaking
and needs to be replaced, if the applied pressure still cannot
be obtained.
If functionality of Hand Pump is not normal, please do not
Continue Pumping.
