11. The Isolation valve may be closed if
desired to maintain pressure in the item
under test, but it must be remembered
that if this is done, the pump will not
automatically keep the pressure
topped up.
To release hydraulic pressure:
Make sure the drain hose is directed into a
suitable container or back to the reservoir and
open the pressure let down valve. Liquid will be
discharged along the drain hose.
When releasing hydraulic pressure, it is
important to do so slowly to prevent possible
damage to the hydraulic pressure gauge.
TROUBLE SHOOTING GUIDE ALL AHP MODELS.
Pump will not start:
Check the mains air supply.
Check the regulated air pressure is
available via the air pressure gauge,
mounted on the air regulator.
Check the air valve is turned ON.
If the pump will still not actuate it will
require inspection.
Pump will not build up pressure:
Insufficient air pressure causing the
pump to stall.
Pressure release valve, not closed.
Close to build up pressure.
Insufficient hydraulic fluid, available
from the reservoir.
Tube connections loose in system,
check and rectify.
Strainer in pump suction blocked,
check and clean if necessary.
Loss of pressure may also be caused by
one of two reasons, the hydraulic
check valves have developed a leak,
or the fluid is bleeding past the seals in
the hydraulic cylinder. Get the unit
serviced or repaired.
Pump not running properly:
If the pump appears to be short
stroking and running too fast without
pumping properly, it usually indicates
that the air check assembly is not
working as it should be. Get the unit
repaired/serviced.
Should the pump commence to run
erratically and in a jerky manner after a
period of time it is usually an indication
that a seizing action is taking place in
the hydraulic piston/cylinder assembly.
Foreign matter such as dirt, grit or
chemicals that do not have sufficient

ATDP216,
lubrication qualities being present in
the fluid supply usually causes this. If
the hydraulic piston and cylinder have
not been damaged a thorough
cleaning will normally solve this. The
unit may require service or repair.
For maximum volume of flow, make
sure that a sufficient flow of air is
supplied to the pump. Using a smaller
pipe than the "Air In" port of the pump
will not allow it to run at its full rated
capacity. Long runs of relatively small
pipe supplying air to the pump will
have the same effect.
If an excessive amount of oil or water is
coming through the pump air exhaust,
check the following.
A) The lubricating unit on the air supply
is delivering too much oil. Adjust to
about one drop of oil for every 20
strokes of the pump.
B) The filtering unit in the air supply is
not functioning correctly. The bowl
should be cleaned periodically to
ensure delivery of clean air to the
pump.
C) The fluid being pumped may be
leaking past the seals in the hydraulic
cylinder into the air motor. The unit will
require inspection and repair.
SERVICING
The pack is designed for long and trouble free
service, in a rugged environment with a
minimum of servicing. Regular servicing is
confined to:
Topping up the air lubricator.
Regular draining of the air filter bowl.
Occasional cleaning of the air filter
bowl using warm soapy water only.
WARNING: shut off the air supply before
removing the air filter bowl.
