New Machine Break-In
1. Start the engine and run at low idle until it reaches proper operating temperatures. Do not move the controls.
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 engine coolant temperature. Shut
down the machine at the first indication of an abnormal reading.
5. Avoid running the engine at high idle for long periods of time.
6. Manage engine power to allow acceleration to governed speed when conditions require more power. Do not
over-rev the engine.
7. Always allow the engine to cool before shutting it off.
8. After shutting off the engine, check the engine fluid levels.
NOTICE!
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
new 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
by allowing time for internal engine parts to break-in. Make sure the machine is in normal
working condition before proceeding with the break-in.
