During excavator operation, prevent the base from collapsing and falling stones above, avoid the collision between the bucket and the car compartment, and prohibit the bucket with materials from passing through the cab of the car or above the personnel. In addition, excavators shall not be allowed to operate on soft ground or swamp and in an environment exceeding the allowable water depth.
Before moving the machine, it must be clear whether the direction to travel is consistent with the travel operation pedal or lever. During long-distance walking, rest for 5min every 20min to avoid damaging the walking motor. When walking, pay attention to avoid large obstacles such as large round stones, and it is forbidden to cross the slope with a slope greater than 15 ° to prevent the machine from rollover.
Before excavation, clearly understand whether there are underground facilities or cultural relics in the excavated section. During operation, pay attention to overhead facilities such as bridges and keep a safe distance from high-voltage wires. In order to prevent collapse caused by "undercutting" during operation, avoid hollowing out the soil under the machine.
In cold weather, park the machine on a hard ground to avoid the track freezing with the ground. If the track freezes with the ground, use the boom to support the ground to lift the track, and then move the machine carefully.
