MAN MBE900 Operator's Guide (EN)

MBE 900 OPERATOR'S GUIDE To the Operator personnel to provide prompt preventive maintenance and skilled engine repairs. This guide contains instructions on the safe operation and preventive maintenance of your Detroit Diesel MBE 900 engine. Maintenance instructions cover routine engine services such as lube oil and filter changes in enough detail to permit self-servicing if desired. The information and specifications in this publication are based on the information in effect at the time of approval for printing. Contact an authorized Detroit Diesel service outlet for information on the latest revision. The right is reserved to make changes at any time without obligation.

The operator should become familiar with the contents of this guide before operating the engine or carrying out maintenance procedures. Power-driven equipment is only as safe as the person operating the controls. You are urged, as the operator of this diesel engine, to keep fingers and clothing away from the revolving belts, drive shafts, etc. on engine installation. NOTICE: Coolant must be inhibited with the recommended Supplemental Coolant Additives (SCA) listed in this guide. In addition, the engine can be equipped with a coolant filter/inhibitor system as an installed option or as an after-sale item.

Failure to check and maintain SCA levels at required concentrations will result in severe damage corrosion to the engine cooling system and related components. Throughout this guide CAUTIONS regarding personal safety and NOTICES regarding engine performance or service life will appear. To avoid personal injury and ensure long engine service life, always heed these instructions. Whenever possible, it will benefit you to rely on an authorized Detroit Diesel service outlet for all your service needs from maintenance to major parts replacement.
