3.3) Head rotation
For ease of operation, the tool head can rotate through 90°.
Warning: Do not attempt to turn the head if the hydraulic circuit is pressurised.
4. MAINTENANCE
Air in the hydraulic circuit may affect the performance of the tool; e.g: no advancement or slow
advancement of the lower blade; lower blade 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. 2).
b – Unscrew the main handle (03) from the body (12) to expose the rubber oil reservoir (02).
c – Remove reservoir cap (01).
d – Operate moveable handle, several times, in order to advance the ram (14).
e – Press the pressure release lever (58) to retract the ram (14), 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 – If the oil level is low, top up as directed in § 4.2.
h – Remove all air from reservoir (02) and fit cap (01).
i – Assemble main handle (03) to tool body.
If the tool continues to malfunction return the tool for service/repair as detailed in § 6.
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 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.
