5. MAINTENANCE
Regular routine maintenance should be carried out as follows:
– Lubricate pivot pins (21) of the pedal (23) with drops of oil, to avoid seizure after intensive
use.
– Check oil level in the reservoir (39) (at least every 6 months) and top up if necessary
(refer to point 5.1).
– Eliminate air bubbles or residuals inside the hydraulic circuit (as described in point 5.2).
Non-routine maintenance may be:
– To replace the high pressure hose (refer to point 5.3).
5.1) Oil top up
(Ref. to Fig. 5)
– Raise the end of the pump to help air expulsion and to ease fi lling the reservoir.
– Release the pedal (23) from the latch (13) to more easily reach the reservoir cap (16).
– Unscrew the reservoir cap and top up the oil level until the hole is reached.
– Replace the cap (16).
Always use clean recommended oil, see § 1.
Do not use old or recycled oil.
Do not use hydraulic brake fl uid.
Pumps in the insulated version contain oil with a
high insulating power, do not pollute it with other
types of oil!

!
Ensure that disposal of used oil is in accordance
with current legislation.
5.2) Purge air bubbles or residuals
To purge air from the system proceed as follows:
– Keep the foot pump in a horizontal position at one metre above the connected head.
– Remove the reservoir cap (16).
– Operate the pedal (23) until dies or blades are almost closed.
– Release the oil pressure by pressing the pressure release pedal (63).
– Repeat this operation at least 10 times.
– Fit and retighten the reservoir cap (16).
To purge residuals from the system proceed as follows:
– Keep the foot pump in a horizontal position.
– Disconnect the head from the unit.
– Operate the pedal (23) several times and at the same time keep the pressure release
pedal (63) depressed.
This operation rapidly forces oil through the hydraulic circuits and removes any residual
to the reservoir vent.
