Usually, the new excavator needs some time to trial running, which is called the breaking-in period.The purpose of the breaking-in period is to prevent abrasion in the early phase and prolong the machine’s life. Good maintenance in the breaking-in period is very important, which can lay solid foundation for the machine to perform well in the future.

The speed of the engine in the breaking-in period should be reduced to 30%, and the loads should be reduced to 20%-30%. The engine should be set in idle running with low speed for 3-5 minutes and started to work with loads when the temperature of the cooling water increases to 40℃. The preparation before starting the engine, the technique requirements when the engine is operating and other operating guidelines should be strictly followed as specified.The excavators in the breaking-in period should dig soft soil and the amount should not exceed 50% of the bucket capacity. Later, the loading amount can be increased but should not exceed 75% of the bucket capacity and the operating speed should be reduced.Pay attentions to the conditions of the digger excavator parts and check the temperature of the bearings, gears and other connections. Find the reasons and solve the problems when malfunctions are found.

Except checking the parts, lubrication is also very important. Check the lubricating oil and hydraulic oil, clean and replace if necessary.As an eligible operator, he or she should know well about the conditions of the Sany excavator and master the operating guidelines in the breaking-in period as soon as possible.
