CHANGING FRONT AXLE OIL.

• Oils, filters, coolant, and the battery are considered spe-
cial waste and must be collected and disposed of
according to all anti-pollution regulations in force.
Perform this operation with the machine positioned on level ground and
at operating temperature, so that the oil becomes fluid and can be easily
drained, which facilitates the elimination of any suspended solid
particles.

in a container with suitable capacity. While the oil flows out,
remove plug (1). Use a 17 mm wrench.
2. Once the oil has been drained, reinstall plug (2) and pour oil of the
prescribed type through hole (1), until the level corresponding to
the lower edge of the hole itself is reached.
