Checking the filter box
- It is important to maintain and clean the filter properly,
to ensure the proper operation of the vehicle.
- It is also very important that none of the hoses
from the filter box to the carburettor or to the drainage
box is disconnected, anbd that no holes are
made in the filter box, since this would alter the
carburation and thus adversely affect the life and
duration of the engine.
