Check electrical system:
Inspect all electrical connections and cables and
replace any which are damaged or corroded. Spray
a good quality water inhibitor onto exposed
connections to prevent moisture ingress.
Check rear wheel alignment:
To prevent excessive tyre wear and ensure safe
machine operation, the rear wheels must be
correctly aligned to 'toe - in' by 3 mm (.12˝) - 8
mm (.31˝).
Set the rear wheels in the straight ahead position.
Measure and compare the distance between the
front sidewalls and the rear sidewalls at the wheel
centre height. The distance between the front
sidewalls must be set 3 - 8 mm less than the
distance between the rear sidewalls.
To adjust the alignment of the rear wheels, first
back off the left hand and right hand locknuts on
the track rod assembly. (Left hand locknut is a left
hand thread). Rotate the track rod to achieve the
correct 'toe - in' as described above and tighten the
locknuts securely.
Check the engine overheat warning system:
Turn the ignition key to the 'ignition on' position
'I'. Disconnect the red/grey wire terminal from the
engine temperature switch and touch the metal
terminal of this wire onto a suitable earth point,
ensuring that the metal surfaces make good
contact. The horn will sound and the engine
coolant temperature warning light will illuminate
to confirm correct operation. If the system is faulty,
make repairs before operating the mower.
Check the hydraulic oil overheat warning
system:
Turn the ignition key to the 'ignition on' position
'I'. Disconnect the red/blue wire terminal from
the hydraulic tank temperature switch and touch
the metal terminal of the wire onto a suitable earth
point, ensuring that the metal surfaces make good
contact. The horn will sound and the hydraulic oil
temperature warning light will illuminate to
confirm correct operation. If the system is faulty,
make repairs before operating the mower.
