Page 12: Starting Precautions
STARTING PRECAUTIONS Starting any engine can be dangerous in the hands of inex- perienced people. Before attempting to start any engine, the operator should be fully conversant with starting procedure and controls. - Ensure that the batteries are in serviceable condition and correctly connected. -
Page 13: Starting With Emergency El-Starter
STARTING WITH EMERGENCY EL-STARTER (If fitted) Engine with twin electric starting system. Some users require twin electric starting system. The second starting system, with its own battery, is totally separated from the main starting system. The second starter is located in the rear end of the flywheel housing. -
Page 14: Starting With Spring Starter
STARTING WITH SPRING STARTER (If fitted) The spring loading is fully energised by twelve revolutions of the winding handle. When restarting a hot engine, the starter need only be partly energised. When required, the starter can be unwound without discharging the stored-up energy into the engine flywheel. -

Page 16: Routine Maintenance
ROUTINE MAINTENANCE The engine has passed the Life Boat Engine Test Programme before delivery. Still however the engine is not completely run in. It is recommended to operate the engine moderately during the first hours after it has been put into service. Full speed only for short periods during the first 15-20 hours. -

TIGHTENING SEQUENCES FOR CYLINDER HEAD BOLTS, CRANKCASE DOOR BOLTS AND END COVER NUTS. CHECK OF LUBRICATION OIL LEVEL The lubrication oil level should always be checked before starting. The level should never be allowed to fall below lower mark. Note that the marks indicate correct level when the engine has appr. -
Page 20: Lubrication Oil Change
LUBRICATION OIL CHANGE The oil change should be done when the engine is warm. Remove the oil filler cap, see Fig. 1, position 15, and pump up the oil by means of the sump oil drain pump. Remove the crankcase ventilation hose and undo the filler plug (which also contains the capsize valve) on the top of the valve cover. -
Page 21: Priming The Fuel System
PRIMING THE FUEL SYSTEM The fuel system has to be primed before initial starting, after fuel filter change, if the fuel system has been disconnected, or if the engine has run out of fuel and stops. Start the priming at the water separator. 1. -
Page 22: To Drain The Coolant
TO DRAIN THE COOLANT. Remove the filler cap on header tank. Drain the coolant through tap or plug hole in front of the crankcase, see Fig.10. Close the tap securely after draining. Refill the system with correct water/anti freeze mixture. Let the engine idle for 20-30 minutes with the filler cap off and top up. -
Page 23: Idling Speed Adjustment
IDLING SPEED ADJUSTMENT Start the engine and run until normal operating temperature is reached. Correct idling speed is 950-1000 RPM and is factory set before despatch. Adjustment should only be carried out after consulting SABB MOTOR A.S The idling speed is adjusted with the adjusting screw "A". see Fig. -
Page 24: Alternator Belt Tension
ALTERNATOR BELT TENSION. It is important that the belt tension is checked after an overhaul or when new belt is fitted. New belt tension: A force of 3-3,5 kg to deflect belt 3,5 mm Checking and adjustment at service intervals: A force of 2,2-2,4 kg to deflect belt 3,5 mm CHECK AND CHANGE OF ENGINE HEATER The engine heater is shown on Fig.1, position 4. -

Page 28: Stop Solenoid Description
STOP SOLENOID DESCRIPTION. The stop solenoid has two coils, one for pull and one for hold. When the stop button is pressed, both the pull and hold coil are energised and the plunger retracts. As soon as it "BOTTOMS", the internal switch disconnects the high current winding, and the plunger is kept retracted by the hold coil. -
Page 29: Important
IMPORTANT! If the stop solenoid for any reason has been dismantled, it should be refitted in following way: Move the lever "A" by hand until it rests against the screw "C". Press the stop solenoid plunger fully until it "BOTTOMS". Secure the screw "D"... -
