4. MAINTENANCE (Ref. to Fig. 3)
Air in the hydraulic circuit may affect the performance of the tool; e.g. no lower die advancement,
slow advancement of the lower die; lower die pulsating.
In this case proceed as follows:
4.1) To purge air bubbles from hydraulic circuit
a – Hold tool upright in a vice with handles open (Fig. 3).
b – Using a 2.5mm hexagonal allen key, remove screw (11) and main handle (1) to expose oil reservoir
(13).
c – Remove reservoir cap (12).
d – Operate the movable handle three or four times (10), to advance the ram (3).
e – Depress pressure release pin (8) until ram is fully retracted.
f – Repeat points (d - e) at least five times, to ensure all air bubbles in the hydraulic circuit are purged
into the reservoir.
g – If the oil level is low, top up as directed in § 4.2.
h – Remove all air from reservoir and fit cap (12).
i – Assemble main handle (1), and holding screw (11).
If the tool continues to malfunction return the tool for service/repair as detailed in § 5.
4.2) Oil top up
Every six months check the oil level in the reservoir. If necessary, top up the oil level to the upper lip
of the reservoir and remove all air from the reservoir, see 4.1, points a, b, c, e, g, h and i.
Always use clean recommended oil, see § 1.
Do not use old or recycled oil.
Do not use hydraulic brake fluid.
Ensure that disposal of used oil is in accordance with current legislation.
