WARNING
If compressed air, high-pressure water, or steam hits your body directly or dirt is scattered by the com-
pressed air, high-pressure water, or steam, there is a danger of personal injury. Always wear protective
equipment such as protective eyeglasses and dust mask.
1.
Open hydraulic tank inspection cover (1).
2.
Check the front face of radiator for clogging.
If it is heavily clogged, remove cover (2) from the back of
the operator's seat, and clean it with compressed air, etc.
METHOD FOR CHECKING AND ADJUSTING TRACK TENSION
The wear of the pins and bushings of the undercarriage depends on the working condition and soil conditions.
Check the track tension occasionally and keep it at the standard level.
Perform check and adjustment on a level and firm ground.
METHOD OF CHECKING
1.
Drive the machine forward on a flat place, and stop without
applying the brake.
2.
Place a straight bar between the carrier roller and idler as
shown in the figure.
When clearance (a) between the bar and grouser is 20 to
30 mm at the center, the tension is in the standard range.
If the track tension is not in the standard range, adjust it.
