Operation
General principle
This machine can only be operated by those qualified, experienced operator with excavator operating
certificate, who is allowed to inspect and maintain this machine. Pay attention to:
z
Read carefully and command this book before the starting or the first operation of machine.
z
This book should be placed accessible for the convenience of timely replacement or supplement when
it is lost, damaged or unable to read.
z
Careful check should be done before starting this machine. Use and operate it strictly according to the
safety procedure.
z
Immediate high-speed running is avoided for the engine started at low temperature. The normal
working temperature for oil is 50℃~80℃, if it is below 25℃, warm-up running should be done so
that the oil temperature can be raised to the required one for the operation.
z
While the machine is transferred out of factory, there has been long-term rustproof and anti-freeze
fluid in the radiator, which should be drained out totally to protect the machine from rust if the
machine is stopped for a long time.
z
Winter-use lubricant and diesel fuel should be used in cold winter. The brand is according to this
book. For the cold-start of engine, please refer to operating manual of diesel engine and this book.
z
When a refill is needed for the loss of hydraulic oil, make sure to use the identified clean hydraulic oil.
Oil of different brand is forbidden.
z
Pay attention to the cleanliness of hydraulic oil at any time. If it is aging, bad or not clean enough, be
sure to replace it at once with the new oil. Normally a replacement happens after the running -in of
new machine.
z
The key parts of hydraulic system have been sealed by lead. During the warrant period, the seal can’t
be opened privately by the customer, or it won’t be guaranteed.
z
Before the delivery, the machine has been checked and adjusted strictly. But proper running-in must
be gone through will using the machine, so that all parts can run in very well and the life span of the
machine can be lengthen. The running-in period is 100 hours. For the first 50 hours, only L working
mode namely weak excavating mode is allowed, also the engine power is limited within 80% of full
load to run the machine. During this period, overdue idling is avoided, and all indicating meters
should be checked. The machine should be maintained everyday to avoid of the oil leakage. At the
first 50 hours or working in mud, pins should be lubricated once every 8 hours. After 50 hours, the
torque of tighten parts should be checked and the maintenance be made for the machine. After 50
hours, new lubricant should be added for the diesel engine.
