Introduction
Introduction
PREFACE
- These operating instructions are designed to familiarize the operator with the machine and its designated use. The instruction manual contains important information 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 instruction manual must be supplemented by the respective national rules and regulations for accident prevention and environmental protection. The operating instructions must always be available in the operator’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, troubleshooting 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 prevention 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 construction- machine specialist. They cannot provide basic know-how.
- This can be acquired, for example, in several days’ instruction by a qualified Terex O&K mechanic or by attending an Terex O&K training course for operators or maintenance 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.
- Complies with VDMA recommendation “Operating instructions” All Terex O&K operating manuals are issued in German and then translated. Even a good translation may give rise to questions which Terex O&K will be pleased to answer. The operating instructions are not work instructions for carrying out major repairs. Such work is willingly done for you by the Terex O&K aftersales 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 covering 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 is complete and in the language requested by you.
