z This engine is built exclusively for purpose according to the scope of delivery - defined by the equip- ment manufacturer (use for the intended purpose). Any use abo- ve and beyond this is considered improper use. The manufacturer will not be liable for damages resulting from this. The user bears the sole risk. z Use for the intended purpose also includes ob- servance of the operating, maintenance and re- pair instructions specified by the manufacturer. The engine may only be used, maintained and repaired by persons who are familiar with it and instructed in the dangers.

The pertinent rules for the prevention of acci- dents and other generally recognised safety and industrial medicine rules must be observed. z When the engine is running there is a danger of injury caused by: rotating / hot parts in engines with external ignition (high electri- cal voltage), avoid touching at all costs! z Unauthorised modifications to the engine exclu- de manufacturer liability for resulting damages. z Equally, manipulations to the injection and cont- rol system can affect the engine's performance and the exhaust characteristics. Compliance with legal environmental regulations will no lon- ger be guaranteed in this case.

z Do not modify, obstruct the cooling air flow area to the fan, unhindered cooling air supply must be guaranteed. The manufacturer will accept no liability for da- mages resulting from this. z Only DEUTZ original parts may be used when carrying out maintenance/repair work on the en- gine. These have been designed especially for your engine and ensure a trouble-free operation. Failure to observe this will void the warranty ! Maintenance/cleaning work on the engine may only be carried out when the engine is not run- ning and has cooled down. When doing this, make sure that the electrical systems are switched off (remove ilgnition key).

The specifications for accident prevention with electrical systems (e.g. -VDE-0100/-0101/-0104/ -0105 Electrical measures against dangerous touch voltages) must be observed. Cover all electrical components tightly when cleaning with liquids. z Do not work on the fuel system when the engine is running - Danger to life . Wait for the pressure to drop after the engine co- mes to a standstill (in engines with DEUTZ Com- mon Rail about 5 minutes, otherwise 1 minute) because the system is under high pressure Dan- ger to life . During the first trial run do not stand in the dan- ger area of the engine. In case of leaks danger due to high pressure - Danger to life .

Go to the workshop ilmmediately in case of leaks. Make sure the engine is not started acciden- tally during repairs when working on the fuel system - Danger to life . Caution This symbol indicates a danger to the component / engine. The appropriate instructions must be followed otherwi- se the component / engine may be de- stroyed. Danger This symbol is used for all safety in- structions which, if not observed, pre- sent a direct danger to life and limb for the person involved. Observe these carefully. Also pass on the safety in- structions to your operating personnel. Furthermore, the legislation for "gene- ral regulations for safety and the pre- vention of accidents" must be observed.
