Accidents can be prevented by knowing beforehand conditions that may cause a hazard when performing operation and maintenance.
This loader is a machine with independent transmission, moving on chains or wheels. Driving in forward direction, the loader can load or dig material using its attachments intended for loading operations (i.e. bucket).
This KOMATSU machine is designed to be used mainly for the following work:
? Digging work
? Smoothing
? Pushing work
? Loading work
For details of the operating procedure, see “Work possible using wheel loader (3-135)”.
