Risk of accidents if maintenance work is not carried out!
Have the maintenance work on the main boom locking system performed
regularly by
Manitowoc Crane Care or an authorised GROVE dealer.
This prevents the complete unlocking of a telescopic section in Emergency
operation/Emergency program mode, which could cause serious accidents
and damage to the truck crane.
