Changing the Hydraulic Oil Return Filter for the
Variable Pump*
The hydraulic oil return filter with service indicator is located
at the rear right hand side of the tractor below the cabin.
ATTENTION
The hydraulic oil return filter must be replaced
if the pressure at the service indicator (1) rises
to 3 bar pressure when the engine is at idling
speed and the implement variable pump is
running when equipment (for example spiral-
bladed lawn mower) is installed.
- Relieve any pressure in the hydraulic system by
turning the implement off.
- Loosen the hydraulic oil return filter (2) with a filter
wrench.
ATTENTION
Observe the instructions for handling fuels
and lubricants.
