mulators (1) that contain nitrogen.
The filling pressure at 20 °C (68 °F) is 50 bar
(725 psi).
• Have the filling pressure checked, and if nec-
essary corrected, by
Manitowoc Crane Care or
an authorised GROVE dealer or an author-
ised specialist workshop.

Risk of accidents due to incorrect inspection
