Compact excavator Maintenance Techniques

Compact excavator is widely used in engineer construction, where accidents may happen if notices are not paid enough. When the digger is working, none of the people should climb the machine or pass any items. Maintenance should not be done when the machine is working, which may cause unnecessary accidents. The hydraulic system, electric control system should not be adjusted casually and the operation should be done as specified. When discharging, the digger should start to work after the dump truck stopped stably. The digger should not collide with any parts of the dump truck when discharging and the bucket should not pass over the cab of the dump truck. The bucket should not be used to crush big and hard objects, which should be removed first.

The fuel oil should be chosen according to the ambient temperature, different bands and specifications should be matched with different working conditions, which is very important to keep the compact excavator in highly efficient. The fuel oil should not mix with any impurities, dust or water, all of which may cause serious abrasion to the fuel pump. The fuel tank should be fully filled to avoid any water producing in the interior of the tank.

Lubricant can reduce abrasion to the machine surface. It is very important to keep the lubricant clean and purified, otherwise, the lubrication will not work. Dust, sand, water and other impurities should not mix with lubricant. The filter can prevent the impurities entering fuel oil or other parts, thus it is very necessary to change the filter regularly and keep it clean. All of the above guidelines are very important and effective to keep the compact excavator in a good condition and make the maximum profits for the customers. If you want to maintain your machine well, just follow these guidelines.
