35) CHECK AND SUPPLYING AXLE OIL
(1) Move the machine to flat ground.
(2) Open the axle air breather to relieve internal air
pressure.
(3) Remove the plug and check the oil amount.
It is normal if the oil level is at the hole of the
plug.
Provide fill & level plug with O-ring and
install it.
When checking the oil level, press the park-
ing brake switch and fix front and rear
frames using the safety lock bar.
As the machine is hot after operation, wait
until the oil temperature has dropped.
Set the plug of planetary gear in parallel to
the ground.
