6.3.10 MAINTENANCE OF STEERING
6.3.10
Regularly check that there is not excessive looseness between the cogged steering segment and the steering wheel
pinion. If higher looseness is identified, it is necessary to limit it. Procedure for limiting (adjusting) looseness:
►
Lift the hood.
►
Loosen nut M12 (
1
) on the bolt of the eccentric.
►
Place a suitable wrench on to the hexagon of the eccentric (
2
) and turn it until looseness is limited to a minimum.
►
Tighten nut M12 (
1
) using a torque of
35 - 45 Nm
.
Neglecting this maintenance may result in damage to steering components.
6.3.11 CHECKING AND ADJUSTING THE TRAVEL DRIVE BELT
Regularly check the condition and tension of the travel drive belt. As soon as the belt starts to slip through or even produce an
odour, it is necessary to tension or replace it.
►
Take off the mowing deck cover ( 6.3.7a).
6.3.11
►
By tightening the nut on the bolt, set the spring to a length of
55 ± 1 mm
.
Do not over-tension the belt above this level, this will reduce its lifetime and may also cause damage to the transmission!
6.3.12 REPLACING BELTS
Replacing drive belts is a relatively demanding operation, which needs to performed by an authorised service centre.
6.3.13 REPLACING WHEELS
Before replacing one of the wheels, park the machine on a horizontal and rigid surface, turn off the engine and remove the key from
the ignition. Perform the replacement as follows:
6.3.13
►
Lift the machine using an appropriate jack on the side where you will perform the replacement. Locate the jack
under a solid part of the frame or on the arm of the transmission. Using a wooden block, secure the machine to
prevent it rolling off.
CAUTION
– when lifting the machine on the left side, take care not to lift it too high. The side
discharge cover on the right side of the mowing deck could be damaged.
►
Remove the protective cover (
1
) from the wheel (only the front wheels).
►
Using a suitable screwdriver remove the retaining ring (
2
) and remove the washer (
3
).
When reattaching the wheel proceed in the reverse sequence to its removal. Before attaching the wheel clean all parts and lightly
grease the shaft with a plastic lubricant. Especially for wheels on the rear axle this
lubrication is essential for the subsequent
removal of the wheel. In the event that lubrication is not performed the subsequent attachment may be very difficult.
When attaching the rear wheel pay attention to the mutual alignment of the pin on the shaft and the groove on the wheel.
6.3.14 REPAIRING A TYRE PUNCTURE
The machine is equipped with tubeless tyres. In the event of a puncture have it repaired at a specialised tyre repair shop or at an
authorised Seco machine service centre.
6.3.15 MAINTENANCE OF THE HYDROSTATIC TRANSMISSION
For the reliable operation of the transmission it is necessary to maintain the correct oil level. The filling opening of the transmission
is shown in figure
6.3.15. Details are included in the manual of the manufacturer that supplied the machine part.
In the event of problems with the transmission immediately seek the help of an authorised service centre, there is a risk of serious
damage.
