It is advisable to rotate the motor shaft at least once a month, if it is done manually, it should be at least five turns, causing the shaft to be in a different position from the previous one. If the engine has a device that locks the axle, it must be removed before turning the axle, and then replaced again before carrying the engine.
Vertical motors can be stored in an upright or horizontal position. For open-rolling motors stored for more than six months, bearings must be relubricated prior to operation. If the engine is stored for more than two years, it is recommended to replace the bearings or to remove, wash, inspect and re-lubricate the bearings.
In the case of oil lubricated bearing, the motor must always be stored in its original operating position and with oil in the bearings. The oil level must be respected, always at the middle of the level display. During the storage period the shaft locking device must be removed and the shaft rotated by hand so that the oil recirculates and keeps the bearing in good condition.
