1、停放不隨意，更好將挖掘機加長臂停放于干燥的室內；條件所限只能停放于室外時，應選擇堅實平坦的地面，盡量避免潮濕、鹽堿、多粉塵等惡劣的環境，有條件的話，找幾塊布料將裸露在外的油缸進行遮蓋。
1. Do not park at will. It is better to park the excavator with extended arm in a dry room; When conditions are limited to parking outdoors, solid and flat ground shall be selected to avoid harsh environment such as humidity, saline-alkali and dust. If conditions permit, several pieces of cloth shall be used to cover the exposed oil cylinder.
2、防銹要上心，停放時，盡可能的把裸露在外的油缸收回去，防止外物磕碰和潮濕的雨雪天氣對油缸的腐蝕，進而造成破壞或生銹。如果場地有限，油缸不能完全收縮回去，可以在裸露的油缸活塞桿表面涂抹一層黃油，防止生銹。
2. Take care to prevent rust. When parking, take back the exposed oil cylinder as much as possible to prevent damage or rust caused by collision of foreign objects and corrosion of the oil cylinder in wet rain and snow. If the site is limited and the oil cylinder cannot be fully retracted, a layer of grease can be applied on the surface of the exposed oil cylinder piston rod to prevent rust.
3、保存好體力，蓄電池在寒冷的環境下容易虧電，如果條件允許的話拆下蓄電池放到室內存放。
3. Keep your physical strength well. The battery is easy to lose power in cold environment. If conditions permit, remove the battery and store it indoors.
4、注意防盜喔，工程設備停放于室外時，一定要檢查、清空工程設備內的貴重物品，防止物品丟失被盜。
4. Pay attention to anti-theft. When the engineering equipment is parked outdoors, it is necessary to check and empty the valuables in the engineering equipment to prevent loss and theft.
為挖掘機加長臂可以配合操縱工作臂油缸及挖掘斗油缸的伸縮作業，可使挖掘斗的活動范圍擴大一倍以上，讓挖掘機加長臂可以挖得更深，更遠，正是因為挖掘機加長臂的開創性意義重大，很多大型工程已經慢慢開始引用挖掘機加長臂了，所以挖掘機加長臂廠家也在不斷改進加長臂，可以使得更好地方便我們使用，在其他類似的工程施工中也是具有非常好的借鑒意義。
The extension arm of the excavator can cooperate with the telescopic operation of the operating arm oil cylinder and the bucket oil cylinder, which can expand the scope of the bucket more than twice, so that the extension arm of the excavator can dig deeper and farther. It is precisely because the pioneering significance of the extension arm of the excavator is significant, and many large projects have slowly begun to use the extension arm of the excavator, so the extension arm manufacturers of the excavator are also constantly improving the extension arm, It can make it easier for us to use in other similar projects.
