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 prevent 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 - Connections checking
Check the hydraulic and pneumatic connections once a week. Ensure that the couplings 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.10, page 3).
l Use a slotted tip screwdriver of the appropriate size to unscrew the filter from the air inlet connection until it is
extracted.
l Clean the filter with compressed air and then refit and screw it into position. Do not over-tighten the filter or damage
may ensue.
l Reconnect the air line quick coupler after binding the thread with Teflon tape.
If the air filter is excessively contaminated or damaged, it must be renewed. Order a new filter from the manufacturer,
referring to the list of spare parts at the end of this manual.
7.3.1 - Checking the hydraulic oil on the 2,5 Lt. pump.
Periodically check that the pump contains the correct quantity of hydraulic oil by checking the level on the sight glass
(fig.11a, page 3). If the oil level, with cylinder closed, is below minimum (E, fig.11a), refill using the reccomended types
of oil on page 14.
7.3.2 - Checking the hydraulic oil on the 5 Lt. pump.
Periodically check the oil level, which must be between the two notches on the oil cap dipstick (F in fig.11b, page 3).
If the oil level, with cylinder closed, is below minimum, refill using the reccomended types of oil on page 14.
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:
l If the pump is mounted vertically, disassemble it and position it horizontally.
l Use a slotted tip screwdriver to remove the filler plug (fig.12, page 13).
l Empty the pump of oil by turning it upside down over a suitable container.
l Allow all the oil to flow into the container and then fill the pump with the quantity and type of new oil specified on
page 14.
l 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.
