1、 Prevent engine idling

即使是在空转，液压泵内还是会有油在循环并消耗燃料。在日常装车或挖掘过程中，中途可以较长时间停机的时候，尽量不要开着伸缩臂挖机怠速等待，要劳逸结合、更加省油，这是伸缩臂挖机省油诀窍之一。

Even at idle, there will still be oil in the hydraulic pump circulating and consuming fuel. In the daily loading or excavation process, when the machine can be stopped for a long time in the middle, try not to wait at idle speed with the telescopic boom excavator, and combine work and rest to save more fuel. This is one of the fuel saving tips of the telescopic boom excavator.

二， 防止重载失压

2、 Prevent heavy load voltage loss

当挖掘的沙土或石块负荷过重时，即使拉动操纵杆作业机械也无动作，而陷入失压状态。一口气吃不了大胖子这个道理大家都清楚，一铲子不了的问题，可以分为两下来，否则既费机子，又耗油，就得不偿失了。

When the excavated sand or stone is overloaded, the operating machinery will not move even if the joystick is pulled, and will fall into the state of pressure loss. We all know that the problem that can't be solved with one shovel can be solved in two ways. Otherwise, it will cost more money and fuel.

三，降低发动机转速

3、 Reduce engine speed

虽然降低发动机转速会影响作业量，但却可以大幅降低燃耗，提升燃耗效率。当然，前提是不会致使干活效率太低，那样的话，可能引起雇主的反感而失去到手的活儿。

Although reducing the engine speed will affect the work volume, it can significantly reduce fuel consumption and improve fuel consumption efficiency. Of course, the premise is that the work efficiency will not be too low. In that case, the employer may be disgusted and lose the job.

四，减小回旋角度

4、 Decrease the swing angle

伸缩臂挖机省油诀窍之减小回旋角度，减小在向自卸卡车装载时的回旋角度可以缩短作业周期，增加单位时间内的作业量，从而提升燃耗效率。这也是 有效的一种省油方法，很多机手在进行装车作业，很多时候往往想不到这点，因而多花了一部分冤枉的油钱。

The key to fuel saving of telescopic excavator is to reduce the swing angle and reduce the swing angle when loading to the dump truck, which can shorten the operation cycle, increase the work volume per unit time, and improve the fuel consumption efficiency. This is also an effective way to save fuel. Many operators are carrying out loading operations, and often do not expect this, so they spend a part of the unjustified fuel money.
