TO HANDLE A NEW
EXCAVATOR
All DOOSAN Daewoo excavators are inspected and adjusted
before leaving the factory. However, it is required that the
operator follow these steps during the initial break-in period.
Failure to follow these steps may result in damage to the
equipment or reduced performance.
If machine is used at full load before it is broken in, it may affect
the life cycle and safe running operations. This could lead to
problems later.
NOTE: 1. Check daily for leakage of coolant, fuel, engine
oil and hydraulic oil.
2. Inspect all lubricants daily, add appropriate
lubricants as required.

gauges from time to time.
