Remark
Your Komatsu machine has been thoroughly adjusted and tested before shipment from the factory. However,

Make sure that you fully understand the content of this manual, and pay careful attention to the following points when
breaking in the machine.
• Run the engine at idle for 15 seconds after starting it. During this time, do not operate the control levers or fuel control
dial.
• Idle the engine for five minutes after starting it up.
• Avoid operation with heavy loads or at high speeds.
• Immediately after starting the engine, avoid sudden starts, sudden acceleration, unnecessary sudden stops, and sudden
changes in direction.
