Komatsu Galeo PC27MR-2 Operation & Maintence Manual page 139

OPERATION
Always maintain the rubber shoes at the proper tension to prevent them from coming off.
If the tension is low, the rubber shoes will come off under the following conditions.
Even if the tension is correct, be extremely careful when carrying out operations.
1. Avoid operating the steering when traveling over curbs, rocks,
or places where there is a big difference in height (more than
approx. 20 cm (8 in)). When traveling over such objects,
always
travel at right angles to the object.
2. When traveling in reverse up a slope, do not turn when moving
from flat ground onto the slope.
If it is necessary to turn on slopes, be sure to turn gradually.
3. Avoid traveling along the edge of slopes or on rough ground
with the track on one side raised (with the machine tilting at an
angle of more than approx. 10°) and with the track on the other
side on flat ground. To avoid damage to the rubber shoes and
road liners, travel with the tracks on both sides on
flat ground.
4. If the machine is operated as explained in 1 to 3 above, the
rubber shoes is slackened. Do not steer the machine in the
positions shown in the figure.
