4. MAINTENANCE
Air in the hydraulic circuit may affect the performance of the tool; e.g. no advancement, slow ad-
vancement or pulsation.
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. 13).
b – Unscrew the main handle (7) from the body (5) to expose the rubber oil reservoir (10).
c – Remove reservoir cap (11).
d – Operate moveable handle (6) several times, in order to advance the ram (3).
e – Press the pressure release lever (8) to retract the ram (3), discharge oil pressure from the circuit
and return all oil to the reservoir.
f – Repeat points (d - e) five times, to ensure all air bubbles in the hydraulic circuit are purged into
the reservoir.
g – Remove all air from reservoir.
If the oil level is low, top up as directed in paragraph 4.2.
h – Fit reservoir cap (11).
i – Assemble main handle (7) to tool body.
If the tool continues to malfunction, return the tool to Cembre 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 top lip
of the reservoir and remove all air from the reservoir, see 4.1, points a, b, c, and e, finally, complete
with operations h and i.
