TEST SETUP
Slowly apply pressurized air.
NOTE: If pressure rises quickly within a few
strokes of pump, inlet valve is likely clogged.
Refer to
INLET CHECK VALVE TEST
in this sub-
section.
When pressure has reached 2.8 kPa - 7.6 kPa
(.4 PSI - 1.1 PSI) the pressure relief valve should
open preventing a further increase in pressure.
When valve opens, pressure must drop at pump
gauge.
If pressure increases above specification or gauge
does not drop to zero, replace outlet valve.
Install a
SMALL HOSE PINCHER (P/N 295 000 076)
near outlet valve.

NOTE: To validate outlet hose, connection and
valve altogether, a test cap (P/N 293 000 105) or
an equivalent hand made plug (such as a capped
vent hose) can be installed to the outlet nipple of
the valve.
