The starter motor requires very little attention beyond keeping the commutator clean and free from oil, brush dust, etc, as with the dynamo. Although the starter will turn the engine over, however stiff, the working life of the motor can be increased by turning the engine over by hand for two or three revoloutions, as this will considerably diminish the load for starting, especially in cold weather.
If the starter pinion jams when operating the starting motor switch, it can be released usually by turning the squared end of the starter shaft by means of a spanner. To obtain access to this squared end, withdraw the metal cap protecting it.
IMPORTANT Never use the starting motor to propel the car as it causes too great a strain upon the battery and starting motor. Also should the engine fail to start at the first attempt, don't press the starter switch until the engine is still, or the starter pinion or teeth with witch it meshes on the flywheel may be damaged.
