TER
DANGER
• Soon after the machine has been stopped the hydraulic oil
is very hot; let it cool down until it reaches a temperature of
40-45°C before changing it.
• The hydraulic system is pressurized; after stopping the en-
gine, move the control levers more than once in all direc-
tions to release the residual pressure.
• Oils, filters, coolants and batteries are considered special
waste and must be collected and disposed of according to
the anti-pollution regulations in force.
This operation must be carried out every time the hydraulic sys-
tem oil filter is changed.
The filter can be reached by opening the engine hood; to change
it, proceed as follows:
1- Unscrew the filter holder (1) and remove the used filter. Use a
22 mm spanner.
2 - Install a new filter with the relevant gasket after cleaning the
disassembled parts and the inside of the filter holder (1).
• After changing the filter, let the engine idle for 2-3 minutes.
