Small excavators should be parked on solid, flat ground when working. Outriggers should be mounted on small tires. If the weather is cold and the mini excavator is down for a long time, please drain the engine coolant.
The wheelbase of the track of the small excavator on the ground is always greater than the wheelbase, so the forward working stability is good, and the lateral working should be avoided as much as possible; the digging point should be close to the machine to improve the stability; the digging point should be far away from the machine, which will cause the center of gravity Moving forward, the operation is unstable; lateral excavation is not as stable as forward excavation. If the digging point is far from the center of the fuselage, the machine will be more unstable. Therefore, an appropriate distance should be kept between the excavation point and the center of the machine body to balance the work.
During the dragging operation of the small excavator, when the shovel is full, do not continue to shovel to prevent overloading. When dragging ditches, ditches, foundation pits, etc., the distance between the machine and the excavation slope should be determined in consultation with the construction personnel according to the depth, soil quality, slope, etc.
Using the bucket of a small excavator to dig rocks will cause great damage to the machine and should be avoided; when excavation is required, the position of the body should be adjusted according to the direction of the rock cracks so that the bucket can be smoothly shoveled in for excavation; insert the rock gap, use the stick and Use the digging force of the bucket to excavate (note that the bucket teeth slip); the unbroken rock should be broken first, and then excavated with the bucket.
