Hydraulic System
Maintenance
WARNING
Hydraulic fluid escaping under pressure can
penetrate skin and cause injury.
• Make sure that all hydraulic-fluid hoses and
lines are in good condition and all hydraulic
connections and fittings are tight before
applying pressure to the hydraulic system.
• Keep your body and hands away from pin-hole
leaks or nozzles that eject high-pressure
hydraulic fluid.
• Use cardboard or paper to find hydraulic leaks.
• Safely relieve all pressure in the hydraulic system
before performing any work on the hydraulic
system.
• Get immediate medical help if fluid is injected
into the skin.
Servicing the Hydraulic
System
Service Interval: Every 500 hours
Note: Keep water away from electrical components. Use a
dry cloth or brush to clean such areas.
This procedure is best carried out when the hydraulic fluid is
warm (not hot). Lower the cutting units to the ground and
drain the hydraulic system.
1. Remove the hydraulic tank drain plug and let the oil
flow into the drain pain.
2. When the oil stops, install the drain plug with a new
seal.
3. Remove the oil tank suction flange to gain access to
the suction strainer.
4. Unscrew and remove the strainer and clean with
paraffin or petrol before installing.
5. Install the return line oil filter element.
6. Install the transmission oil filter element.
7. Fill the hydraulic tank with fresh, clean hydraulic fluid
of the recommended grade.
8. Run the machine and operate all hydraulic systems until
the hydraulic fluid is warm.
9. Check the fluid level and top up as necessary to the
upper mark on the sight-level gauge.

1. Temperature switch
1. Turn the ignition key to the ignition on position I.
2. Disconnect the red/yellow wire terminal from the
hydraulic-tank-temperature switch.
3. Touch the metal terminal of the wire onto a suitable
earth point, ensuring that the metal surfaces make
good contact.
The horn sounds and the hydraulic-fluid-temperature-warning
light illuminates to confirm correct operation. If necessary,
make repairs before operating the mower.
