PREFACE:
These operating instructions are designed to fa- miliarize the operator with the machine
and its designated use.
- The operating instructions contain important in- formation on how to operate the machine
safely, properly and with maximum efficiency. Observing these instructions helps to prevent
hazardous situations, to reduce repair costs and downtimes and to increase the
reliability and service life of the machine. - The operating instructions must be supplemented by the respective national rules and
regulations for accident prevention and environmental protec- tion. - The operating instructions must always be avail- able in the driver’s cab of the machine.
The operating instructions must be read and put into practice by any person in charge of
carrying out work with or on the machine, such as
▪ operation, including setting-up, troubleshoot- ing in the course of work, care,
evacuation of production waste and disposal of fuels and consumables,
▪ maintenance (inspection, servicing, repair) and / or
▪ transport.
- In addition to the operating instructions and the mandatory rules and regulations for
accident pre- vention and environmental protection in the user’s country and at the place where the
machine is to be used, the generally recognized technical rules for safe and proper working must be
observed ¹ - The operating instructions are directed to the con- struction-machine specialist. They cannot
provide basic know-how. This can be acquired, for exam- ple, in several days’ instruction by
a qualified Terex O&K mechanic or by attending an Terex O&K training course for
operators or main- tenance personnel. - The Terex O&K after-sales service will be pleased to deal with any queries you may
have after reading through the operating instructions. - All Terex O&K operating manuals are issued in German and then translated. Even a good
transla- tion may give rise to questions which Terex O&K will be pleased to answer. - The operating instructions are not work instruc- tions for carrying out major repairs. Such
work is willingly done for you by the Terex O&K after- sales service. - The documentation relating to the machine is listed according to scope, quantity and language in
the shipping note of the machine or in the cov- ering letter if supplied separately. The operating
instructions and spare-parts list are marked with the serial number of the machine. - On taking receipt of the consignment, please check that the documentation i complete and
in the language requested by you.
