Safety Rules
Accumulators
DANGER!
Be especially careful when working on
the accumulators!
Accumulators are under high pressure!
With valve-controlled accumulators – as for example
on the Autopilot, Auto-Contour and on the concave
adjustment – first slacken off the short-circuit bolt
before carrying out any repair work on the accumula-
tor. This is necessary to relieve the hydraulic pressure.
The accumulators on the radial spreader and on the
standard spreader do not allow relieving the hydraulic
pressure using a valve. The unit in question must be
moved to a position where the hydraulic pressure is as
low as possible. However, residual oil pressure in the
lines cannot be excluded.
Relieving the Auto-Contour accumulator
Relieve the oil pressure from accumulator (D).
This is done as follows:
Slacken off lock nut and back off screw (S) slightly
until the oil pressure has been relieved. Then tighten
screw (S) again up to the stop and tighten lock nut.

Relieving the Autopilot accumulator
Relieve the oil pressure from accumulator (D).
This is done as follows:
Slacken off lock nut and back off screw (S) slightly
until the oil pressure has been relieved. Then tighten
screw (S) again up to the stop and tighten lock nut.
