Filler/level plug
(3) Breather
The breather installed on the upper side of transmission is designed to relieve the pressure gen-
erated inside the transmission during the operation of the vehicle. Therefore, it is desirable to
always keep the breather clean so that it can perform satisfactorily all the time.
(4) Inspection of oil system
Air under pressure condenses into moisture in some degree depending on changes in atmospheric
temperature and atmospheric pressure.
Air under pressure in the air tank should be relieved once or more a week. Especially, in cold
weather, relieve the air every day so that rust, foreign substances, or moisture may not enter the
air pipe.
The entry of foreign substances into the air pipe will cause not only damage or malfunction to the
range change and splitter cylinder seal but also harm to the brake system.

vehicle on a level ground and allow some length
of time to pass, then open the level plug for
check and fill the tank as required.
