8.1 Releasing pressure in the accumulators for
hydraulic suspension
When disassembling the components and pipings
in the hydraulic suspension, release pressure in
the accumulators beforehand in the method
described below.
1. Perform vehicle height increasing operation of the
crane in on-rubber operation configuration. After
the suspension is extended to its stroke end, lock
the suspension.
2. Extend the outrigger jacks to make the 6 wheels
clear of the ground.
3. After setting the outrigger extension/retraction
selector to the neutral, press the suspension free
switch.
[NOTICE]
Before proceeding to the next step, wait at least
20 seconds after you press the switch.
4. Loosen the pipes (2 places) connected to the
extension port of suspension valve carefully and
slowly. If no pressure remains, you can remove
the clasps. If pressure remains, repeat the step 3..
