挖掘機的基本操作，確認挖掘機周圍無障礙物，和學開車一個道理，先觀察好周圍車況；上車后先鳴笛，起到警示路人的作用；

The basic operation of an excavator is to confirm that there are no obstacles around the excavator, and to learn how to drive, first observe the condition of the surrounding vehicles; After getting on the car, honking the horn first serves as a warning to pedestrians and also serves as a safety warning for He Zha;

確認儀表上無報警，車輛無異常情況；將切斷閥旋到ON啟動；其具體操作分為四個動作：大臂、小臂、鏟斗、旋轉， 有的小機器還有一個推鏟。

Confirm that there are no alarms on the instrument panel and that the vehicle has no abnormal conditions; Turn the shut-off valve to ON to start; The specific operation is divided into four actions: boom, forearm, bucket, rotation, and some small machines also have a push shovel.

挖掘機的注意事項：

Precautions for excavators:

1、挖掘機行走時，工作裝置應盡量折疊，靠近機身中心，以保持穩定性；主減速器應放在后面，以保護主減速器。盡量避免穿越樹樁、石塊等障礙物，防止軌道扭曲；如需穿越障礙物，應保證軌道中心在障礙物上。

1. When the excavator is walking, the working device should be folded as close as possible to the center of the body to maintain stability; The main reducer should be placed at the back to protect it. Try to avoid crossing obstacles such as tree stumps and stones to prevent track distortion; If crossing obstacles, ensure that the center of the track is on the obstacle.

2、通過土墩時，一定要用工作裝置支撐底盤，防止車輛劇烈搖晃甚傾翻。避免在陡坡上長時間怠速，否則會因油位角的變化而導致潤滑不良。

2. When passing through earthen mounds, it is necessary to support the chassis with a working device to prevent the vehicle from violently shaking or even tipping over. Avoid idling for a long time on steep slopes, otherwise poor lubrication may occur due to changes in the oil level angle.

3、作業時，要確認履帶的前后方向，避免造成傾翻或撞擊。

3. When doing homework, it is important to confirm the front and rear directions of the tracks to avoid tipping or impact.
