EXCAVATOR OPERATION
CONTROL OBSERVATIONS DURING
OPERATION
Stop the Engine immediately if:
Sudden increase or decrease in engine
rpm's occurs.
Sudden abnormal noises occur.
Exhaust gases turn suddenly very dark.
Make following control observations during
operation to be sure that everything
functions normally.
RUNNING-IN OF THE NEW
EXCAVATOR
The operation and care of the new excavator
infl uences 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 fi rst 50 work hours. Do not work with
full engine 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.
Do not Work with Full Engine
Rpm's or Full Loads during the
First 50 Working Hours
Let the engine warm up suffi ciently in
the cold season.
Do not let the engine rev-up more than
necessary.
Oil Change in the Run-in Stage
The lubrication oil plays a specifi c and
important role during the run-in phase of the
excavator. The numerous movable parts are
not yet run-in, so many fi ne metal particles
are generated and cause damage and
shorten the lifetime of many components.
Pay attention to the oil-change intervals
and complete them sooner than later.
See the subject "REGULAR CHECKS AND
MAINTENANCE WORK" for more details on
the oil-change intervals.
