machine should be used carefully and should not used with excessive load and high
intensity work. The first 50 hours of the break-in period, only 80% of the work load is
allowed. The use of the machine during the break-in period affects the service life of
the machine.
After the first 50 hours of operation, the machine should be serviced for the first time
according to the inspection and maintenance chart, and the relevant fluids and filters
should be replaced. At the same time, check the contamination level of the hydraulic
oil, the value of which should not be greater than NAS9 level. Otherwise, replace the
hydraulic oil.
When the hydraulic system is not working, the engine should not be allowed to run at
high speed.
Only when the hydraulic oil temperature is over 20 degrees Celsius, the work device
can be operated.
