5. MAINTENANCE
Air in the hydraulic circuit may aff ect the performance of the tool; e.g: no lower blade advancedment,
slow advancement of the lower die; lower blade pulsating.
In this case proceed as follows:
5.1) To purge air bubbles from hydraulic circuit
a – Hold tool upright position in a vice with handles open (Fig. 4).
b – By an hexagonal 2,5 mm key, remove screw (67) and main handle (04) to expose oil reservoir
(03).
c – Remove reservoir cap (01).
d – Operate three or four times the moveable handle (59), to advanced the ram (39).
e – Depress pressure release pin (75) until ram is fully retracted.
f – Repeat points (d - e) at least fi ve times, to ensure all air bubbles in the hydraulic circuit are into
the reservoir.
g – Remove all air from reservoir.
If the oil level is low, top up as directed in § 5.2.
h – Fit reservoir cap (01).
i – Assemble main handle (04) and holding screw (67).
If the tool continues to malfunction return the tool for service/repair as detailed in § 2.
5.2) Oil top up
Every six months check the oil level in the reservoir. If necessary, top up the oil level to the top lip
of the reservoir and remove all air from reservoir, see § 5.1, points a, b, c and e, fi nally, complete
with operations h and i.
Always use clean recommended oil, see § 1.
Do not use old or recycled oil.
Do not use hydraulic brake fl uid.
Upon its replacement, dispose of used oil strictly conforming with what prescribed by the
relevant norms specifi cally applyling.
