MAINTENANCE
WARNING : PREVENT ACCIDENTS - When carrying out maintenance procedures it is essential that:
- The engine is switched off and the ignition key removed.
- The parking brake is applied.
- There is no pressure in the hydraulic system.
- The cutterheads are fully down on the ground.
- The safety precautions in this manual have been read and understood.
WARNING : PREVENT ACCIDENTS - Stored energy devices and systems are used on the T424 mower.
It is essential that this stored energy is safely dissipated before maintenance or other service or operations
are performed on these devices and systems on the machine.
Dissipate stored energy as described below:
Hydraulics:
Transmission System - Ensure that the machine is on level ground, engage the parking brake and switch the
engine off. Depress the forward and reverse travel pedals alternatively several times.
Cutterhead Lift System - Lower the cutterheads to the ground and switch the engine off. Raise and lower
the lift levers several times leaving them in the 'down/float' position.
Cutterhead Drive System - Lower the cutterheads to the ground with the cutterhead drive switch in the 'off'
position and switch the engine off.
Wing Cutterhead Springs - Lower the wing cutterheads to the ground.
Operator Platform Gas Spring - Raise the platform fully.
IMPORTANT: PREVENT DAMAGE: Regular maintenance is essential for the continued safe oper-
ation of the machine. Correct servicing will prolong the working life of the machine and
safeguard the "Hayter Warranty". Always fit genuine 'Hayter service parts' as these are
accurately matched to the required duty.
Dirt and contamination are the enemies of any hydraulic system. When carrying out maintenance
procedures on the hydraulic system always ensure that the work area and the components are
thoroughly clean before, during and after refitting. Ensure that all open hydraulic lines and ports, etc. are
plugged during maintenance procedures.
The recommended service intervals are based on normal operating conditions. Severe or unusual
conditions will necessitate shorter service intervals.
ALWAYS grease pivot points immediately after pressure washing or steam cleaning, refer - EVERY 50
HOURS, GREASE PIVOT POINTS.
WARNING: PREVENT ACCIDENTS - The engine, transmission oil and hydraulic systems will be hot
after machine use. Allow the systems to cool before working on the machine, particularly before work-
ing on the engine or when changing oil or oil filters.
