New Machine Break-in
NOTE:
The machine has been thoroughly tested and adjusted before shipment. However, initial operation of
the machine under severe conditions can adversely affect the performance of the machine or shorten
the machine life. SANY recommends a break-in period of 100 service hours for a new machine.
Properly breaking in a new machine is crucial for long service life, allowing time for internal engine
parts to break in properly. Make sure the machine is in normal working condition before proceeding
with break-in. Contact a SANY dealer for details on breaking in the engine.
1. Start and run the engine at a low idle until it reaches proper operating temperatures. Do not move the controls
or the throttle.
2. Avoid operating the machine under heavy loads or at high speeds during the break-in period. Operate as much
as possible in the 1/2 to 3/4 throttle or load range. Do not operate this machine with a full load during the
break-in period.
3. Avoid sudden starts, movements, or stops.
4. Monitor the instruments frequently, especially the engine oil pressure and coolant temperature. Shut down the
machine at the first indication of an abnormal reading.
5. Avoid running the engine at idle for long periods of time. Manage engine power to allow acceleration to
governed speed when conditions require more power. Do not over-rev the engine.
6. Always allow the engine to cool before shutting it off.
7. After shutting off the engine, check the fluid levels.
NOTICE!
This machine has undergone thorough adjustment and testing before delivery. Allow the
machine to operate in medium-duty applications to break in the engine and hydraulic system.
Failure to properly break in a new machine may shorten the service life of the machine.
