34 EXCAVATOR OPERATION
EXCAVATOR OPERATION
RUNNING-IN OF THE NEW EXCAVATOR
The operation and care of the new excavator influences
its life span. Your new excavator has been carefully
checked and tested before leaving the factory. In spite of
this, all movable components must run-in during the first
50 work hours. Do not work with full rpm's and full loads
during this period. It is most important to run-in your
excavator properly in order to achieve its full performance
and longevity. During the running-in, the following points
should be adhered to in all cases.
B
Do not Work with Full Engine Rpm's or
Full Loads during the First 50 Working
Hours
A
Let the engine warm up sufficiently in the cold season.
A
Do not let the engine rev-up more than necessary.
B
Oil Change in the Run-in Stage
The lubrication oil plays a specific and important role
during the run-in phase of the excavator. The numerous
movable parts are not yet run-in, so many fine metal
particles are generated and cause damage and shorten
the life of many components. Pay attention to the oil-
change intervals and complete them sooner than later.
See "REGULAR CHECKS AND MAINTENANCE WORK"
section for more details on the oil-change intervals.
