7.3.1 - Checking the hydraulic oil on the 2,5
Litre pump (AHP1120/AHP1120R)
Periodically check that the pump contains the
correct quantity of hydraulic oil by checking
the level on the sight glass (Fig 13). If the oil
level, with cylinder retracted, is below minimum
(E, Fig 13a), refill using the recommended types
of oil.
7.3.2 - Checking the hydraulic oil on the 5/10
Litre pump (AHP1121(R)/ 1122(R)/ 1141/ 1142)
Periodically check the oil level, which must be
between the two notches on the oil cap
dipstick (F in Fig 13b).
7.4 - Hydraulic oil change
Change the oil at intervals of 250 duty hours.
This operation must be performed when the
cylinder is fully retracted: USE ONLY HI-FORCE
HFO46 OIL for your AHP Pump.
If the pump is mounted vertically,
disassemble it and position it
horizontally.
Use a slotted tip screwdriver to remove
the filler plug (Fig 1).
Empty the pump of oil by turning it
upside down over a suitable container.
Allow all the oil to flow into the
container and then fill the pump with
the quantity and type of new oil
specified above.
Clean the filler opening with a clean
cloth and refit the plug, pressing it fully
down or, if necessary, to the partially
inserted breather position.
7.5 - Troubleshooting
The chart below describes the possible issues
that could occur during operation of the
pump, together with an indication of the
appropriate corrective action. If the prescribed
action fails to solve the problem, contact the
