Re-grease with same type of grease*. Lubricate the steering and control wires with engine oil.
TROUBLE SHOOTING SCHEDULE Problem Procedure Engine will not start. • • • • Fuel tank empty. Spark Plug defective. Spark Plug connection defective. Dirt in carburettor or fuel pipe. Starter does not pull round engine. • • • • • • • Battery flat. Bad contact between cable and battery terminal. Lift lever for cutting unit in wrong position. Main fuse blown. The fuse is placed in front of the battery, under the battery cover. Ignition lock faulty. Gear shift/hydrostat pedal not in neutral.
STORAGE Winter storage At the end of the season the machine should immediately be put in order for storage, also if it is going to stand idle for more than 30 days. Fuel which is left to stand for long periods (30 days or more) can leave tacky deposits which can block the carburettor and interfere with the engine. Fuel stabiliser is an acceptable alternative to avoid tacky deposits during storage. If alkylate petrol (Aspen) is used stabiliser is not necessary since this fuel is stable.
