MAINTENANCE – HYDRAULICS

Changing Hydraulic Oil

It is recommended that the machines

hydraulic oil is warm.This will enable

the oil to flow more easily.

Return all Hydraulic Cylinders to their

closed position to return as much

hydraulic oil back to the tank as

possible.

•

Turn engine off.

•

Remove the drain plug (Use a

27mmspanner) at the base of

the tank and drain to an

external container large enough

to hold all the oil.

(Hydraulic

Tank Capacity:450 litres.)

•

Refill the tank until the oil is

between the Min. and max.

marks on the tank gauge

(Item

c).

•

Run the machine and operate

hydraulic equipment to circulate

oil.

•

Stop the machine and top up

the hydraulic system.
