When walking through the mound, the working device must be used to support the chassis to prevent the vehicle from violent shaking or even tipping over.Avoid engine turning over steep slope for long periods of time, otherwise the change of solid oil level Angle will lead to poor lubrication.The long distance driving of the machine will cause the internal rotating temperature of the roller and the final drive to be too high.Lower oil viscosity, poor lubrication.Therefore, should often stop cooling, extend the lower half life.Do not dig under the driving force of walking, otherwise overload will lead to early wear or damage of the main reducer, rail and other external parts of the car.When going uphill, the wheels should be driven backward to increase the adhesion of the grounding runway.When going downhill, the drive wheel should tighten up the track in front to prevent the car body from sliding forward under the action of gravity and causing parking hazards.Keep working devices in front of you to ensure safety when walking on slopes.After parking, gently insert the bucket into the ground and place the block under the track.When walking and turning on steep slopes, slow down, turn left when turning left, and turn right when turning right to reduce the risk of turning on slopes.
