If the pump is mounted vertically,
disassemble it and place it in a
horizontal position on the floor.
Place the treadle at the “PUMP” side.
There is a flat pushbutton beneath the
treadle.
Use one hand to press the “RELEASE”
side of the treadle while pressing the
pushbutton under the “PUMP” side with
your other hand (fig.10, page 13).
Maintain the pressure on the “RELEASE”
side and the “PUMP” pushbutton for
about 15 seconds.
The pump should now work correctly. If you still
have problems, repeat the above mentioned
procedure.
6.3 AHP1120R/AHP1121R/AHP1122R (Hand
Pendant Operation).
The AHP pump is extremely simple to use:
To activate the pump press the button
marked “PUMP” on the hand pendant
(Fig. 16).The pump will start to deliver
pressurized oil and thereby cause the
connected cylinder to advance.
When the button is released, the pump
stops but the pressure is maintained on
the oil side so that the connected
cylinder holds the load in the position it
has reached.
To return the pressure to zero and
hence retract the cylinder to its starting
position,
press the button marked
“RELEASE” (Fig 16).

7 - MAINTENANCE
The routine maintenance work described
below must be performed exclusively by a
skilled technician who has a thorough
knowledge of the pump and its operation and
who has read this manual completely.
Maintenance must be carried out with
maximum caution to avoid possible accidents.
This chapter describes the only maintenance
procedures permitted. Execution of any
unauthorised maintenance work will
automatically invalidate the warranty and free
the manufacturer from all liability.
7.1 - Checking connections
Check the hydraulic and pneumatic
connections once a week. Ensure that the
connections on the pump are screwed down
tightly and show no signs of breakage, cracks
or other damage. Ensure that the hoses are not
damaged in any way (cuts, abrasion, cracks,
etc.).
7.2 - Cleaning the air filter
There is an air filter inside the air inlet
connection (Fig 12).
Use a slotted tip screwdriver of the
appropriate size to unscrew the filter
from the air inlet connection until it is
extracted.
Clean the filter with compressed air
and then refit and screw it into position.
Do not over-tighten the filter or
damage may ensue.
