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 protection. The operating instructions must always be available 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

They cannot provide basic know-how.
- This can be acquired, for example, in several days’ instruction by a qualified GERMANY Germany mechanic or by attending an Terex-Germany training course for operators or maintenance personnel. The Terex-Germany after-sales service will be pleased to deal with any queries you may have after reading through the operating instructions. 1 Complies with VDMA recommendation “Operating instructions” All Terex Germany operating manuals are issued in German and then translated.
- Even a good translation may give rise to questions which Terex Germany 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 Germany 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 covering letter if supplied separately. The operating instructions and spare-parts list are marked with the serial number of the machine.
