WINTER OPERATION
If the scooter is used in winter too, take care to drive slowly and to use brakes carefully on slippery
roads. If all–year–round oil, such as Mobiloil Special, is not used, fill up with winter oil (SAE
30) – at any rate when the temperature drops below 40° F. To economise on weight, the scooter
batteries are correspondingly small. In winter, therefore, they need special attention. The power
required for starting in winter is many times that needed in summer.
Before starting on cold mornings, we recommend rocking the scooter a few times in 3rd gear
so as to free the engine and opening and closing the throttle quickly two or three times. Then
use the starter with the throttle closed, opening the throttle only a little when the starter is turning
the engine. We recommend, when the temperatures are very low, that the Bowden cables be
lubricated with a thin oil, such as MobilFluid 200, to prevent them from freezing solid.
SUMMER OPERATION
During operation in hot summer or in tropical countries, the carburettor inspection door on the
right–hand rear cowling and the seat should be opened after every stop for the sake of efficient
ventilation and cooling. Acid level in the batteries should be checked every week and, if necessary,
fresh distilled water should be added.
