Maintenance
5.12 Tracks
• Track wear can vary according to work and ground conditions.
☞ We recommend checking track wear and tension once a day.
☞ Park the machine on firm, level and horizontal ground to check and perform mainte-
nance.
Raising the machine with the stabilizer blade and the attachment does not
provide adequate safety for work that has to be performed under a raised
machine.
Caution, danger.
☞ Do not allow anyone to stay in the risk zone.
☞ Firmly support the machine with chocks or suitable brackets. Do not dam-
age any parts of the machine as you support it.
Checking the track tension of the rubber tracks
☞ Place the machine on firm, level and horizontal ground.
☞ Raise the machine evenly and horizontally by means of the boom and the stabilizer
blade.
☞ Slowly and carefully actuate the control levers.
☞ The rubber track has a mark B as shown in Fig. 295.
☞ Place the machine so that mark B of the rubber track is between the drive pinion C and
the track tension roller D.
☞ Stop the engine.
☞ Raise the control lever base.
☞ Remove the ignition key and carry it with you.
☞ Use suitable auxiliary means to support the machine.
• Standard play between the shoulder of the sliding block and the contact area of the
second support roller of the drive pinion is 20 – 25 mm (0.78 – 0.98 in).
☞ Set the tension as follows if it is not in accordance with the rated value – see Adjust-
ing track tension on page 5-34.
