Small excavator instruction manual

According to the instruction manual of the small excavator, the bucket should not eat the soil too deeply each time when excavating, and do not lift the bucket too hard to avoid damaging the machine or causing an overturning accident. When the bucket falls, be careful not to impact the tracks and frame. Carefully check the hoses of the cooling system for aging and breakage. If there are any problems, replace them in time because these places are more likely to have problems in winter.

The wheelbase of the small excavator track on the ground is always greater than the wheelbase, so forward working stability is good, and sideways operation should be avoided as much as possible; the excavation point should be kept close to the machine to improve stability; if the excavation point is far away from the machine, it will cause Because the center of gravity moves forward, the operation will be unstable; lateral excavation is less stable than forward excavation. If the excavation point is far away from the center of the machine body, the machine will be more unstable. Therefore, the excavation point and the center of the machine body should be kept at an appropriate distance to ensure balanced operation. Efficient.

When backhoeing, you must wait until the boom stops before shoveling to prevent the bucket handle and the two sides of the boom groove from colliding with each other.

When carrying out hoisting operations with a small excavator, you should confirm the conditions around the hoisting site. The operation method should be micro-operation mode, and the movements should be slow and balanced; use high-strength hooks and wire ropes, and try to use special hoisting devices when hoisting; and make correct adjustments. The position of the bucket should be adjusted to prevent the steel wire rope from slipping; the length of the hanging rope should be appropriate. If it is too long, the hanging object will swing larger and it is difficult to control accurately; the bucket position should be adjusted correctly to prevent the steel wire rope from slipping; construction workers should try not to get close to the hoisting items to prevent danger due to improper operation.

The mini excavator is a multi-purpose earth and stone construction machine. It is mainly used for earth and stone excavation, loading, farmland water conservancy construction, and land leveling, slope repair, crushing, demolition, trenching and other operations. Therefore, it is used in road construction such as highways and railways. It has been widely used in bridge construction, new socialist countryside construction, urban construction, airports, ports and water conservancy construction.
