12.TRACK CHAINS - Checking the sag

WARNING Fluid under pressure; to release the tension of the track chain, follow the procedures in the "Operation and Maintenance Manual".

C

If the sagging of the track chains in section Cincluded between the support roller and the idler exceeds 30 - 40 mm (1 3/16 - 1 5/8 in).

3÷4 cm MAX. DANGER Fluid under pressure. Do not reduce the tension of the track chain by loosening pressure relief valve VS. Do not remove the grease fitting installed on adjusting valve VR.

13.BRAKE SYSTEM -

Operating check

Pump grease into grease fitting I indicated of valve VR of the adjustment cylinder, until the normal tension of the track chain is obtained.

To increase sag, discharge grease from the cylinder, loosening slightly adjustment valve VR and backing the machine up a few yards, if necessary.

Retighten valve VR.

I. Grease fitting; VR. Track chain tension adjustment valve; VS. Pressure relief valve.

Note – The track chain tension must be somewhat lesser in muddy, very wet terrains and when sand, gravel, snow and ice are present.

Check the correct operation of the brake system doing a series of tests with machine at maximum speed descending a slope. When the brake pedal is depressed, the machine must come to a stop after a braking distance that should be sufficiently short and so as to ensure an adequate operational safety.
