Warm-up Operation
Perform the following warm-up steps:
1. After starting the engine, adjust the throttle control lever so the engine runs unloaded at about 1/4 throttle for 5
minutes.
2. Adjust the throttle control lever so the engine runs at 1/2 throttle, then slowly operate the bucket for 5 minutes.
3. Adjust the throttle control lever so the engine runs at a high rpm, then operate the boom, arm, and bucket for 5
to 10 minutes.
Repeat all movements several times to complete the warm-up process. Check the gauges and indicators for normal
operating readings after the warm-up process.
New Machine Break-in
1. Start and run the engine and run 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, except in an emergency.
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.
WARNING!
• In case of emergency, irregular engine operation, or other faults, turn the key switch to OFF
or press the emergency stop switch to stop the engine.
• Do not operate the machine immediately after starting the engine. Insufficient warm-up of
the machine and hydraulic oil may cause slow control response or abrupt movement
during operation, resulting in serious accidents. Warm-up is especially necessary in cold
areas.
Failure to follow these warnings could result in death or serious injury.
NOTICE!
Your machine has been thoroughly tested and adjusted before shipment. However, initial
operation of the machine under severe conditions can adversely affect the performance of a
machine or shorten its life. SANY recommends that you allow a break in period of 100 service
hours for a new machine.
