5 / 629 E Printed in Germany • Modifications, which serve the technical improvements, are reserved.
Design
• Air-cooled single-cylinder 4-stroke Diesel engine.
• Vertical cylinder.
• Light alloy diecast cylinder crankcase.
• Light alloy cylinder head.
• Forged crankshaft
• Light alloy piston for low free forces of gravity.
• Labrication by pressurised circulation of oil, fine screen filtering in main flow.
• Valve control by rocker, push-rods and tappets.
Characteristics
• Direct injection.
• Compression 1:22. Good cold start performance.
• Fuel orientated mixture preparation. Result: excellent exhaust quality.
• Speed regulation by spring-loaded governor.
Proportionality < 5% at 3000 / 3600 r.p.m.
• The control cover houses the governor, the entire valve drive, the injector pump drive
and the automatic decompression system and oil pump.
• Oil drain on both (narrow) sides of the engine. This gives free access of at least one drain
position for almost all installations.
• Dry air filter with paper cartridge and integrated pre-cleaner.
• Cooling fan and AC generator incorporated in the flywheel (not sensitive to dust).
• 4 seperate engine feet permit mounting on uneven foundations.
Differences of level of up to 1 mm can be corrected.
• Exhaust outlet flexible as regards both position and direction of exit.

To achieve the engines maximum life, it is essential that the engine gets serviced meticulously at regular intervals.
During your first installation please make sure that easy accessibility of service and operating points is assured.
The easier the accessibility is, the sooner and more conscientous the engine will be maintened.
Please convince yourself personally that all serve and operation points are easily accessible before delivering your machine to the customer.
Starter-switchboard-instruments incl. LED-display are mounted to the engine or will be delivered upon request as swithboard-instruments with cable (2m) loose. The engine is started and controlled from thisinstrument box. Instrument box and cable harness are part of the additional equipment and supplied according to the number of
electrical safety features which are required. If the engine has to be started at temperatures below - 15 °C, engine must be fitted with a pre-heating system (glow plug) (additional equipment). Further additional equipments include automatic start and stop, remote control etc.Please ask for drawings and wirings diagrams.
