BLOCKING SETTING
The Hydom 4GB hydraulic power pack is delivered from the factory
configured without locking.
To configure other options, you will need to open or close tap A
and/or tap B with a 4mm Allen wrench. The taps are located next to
the speed throttles (see page 4). Caution: do not confuse locking
adjusters (4mm) with speed adjusters (2.5mm).
• Red plug side tap → Selects the locking of circuit B.
• Green plug side tap → Selects the blocking of circuit A.
• Tap closed → Tighten until it stops.
• Tap open → Once the tap is tightened, unscrew it by one and a half turns.
WARNING: When loosening the selectors, avoid
loosening more than 2 turns, as this could cause oil
leakage and render the equipment unusable.
