3. Safety precautions when loader operation
1. Before starting, you should observe whether there are obstacles and pedestrians in front and behind the machine. , lift the bucket about 500 mm above the ground and sound the horn before starting. During driving, high speed gear should be selected depending on the road conditions. Lifting, lowering and flipping the bucket during driving is strictly prohibited;
2. Low speed gear should be selected during operation. When walking, try to avoid lifting the bucket too high. Different shoveling methods should be used according to different soil qualities, and the shovel should be inserted from the front as much as possible to prevent the bucket from being stressed on one side. When operating on a loose and uneven site, the lifting rod can be placed in a floating position to allow the bucket to operate on a flat surface;
3. The driving road should be flat, and it is not allowed to operate on a site with an inclination exceeding the specified limit. The transportation distance It should not be too large. When the bucket is transported with a full load, the bucket should be kept in a low position;
4. When operating on loose and uneven sites, the bucket arm can be placed in a floating position to advance the bucket smoothly. If the propulsion resistance is too great, the shovel arm can be slightly raised. When loading, the bucket should be inserted from the front at low speed to prevent the bucket from being stressed on one side;
5. When unloading soil onto the transport vehicle, the shovel should be moved slowly. The bucket should be at a suitable height, and the forward and return positions must not collide with the car;
6. Always pay attention to the sound of the machine parts, and stop the car immediately if any abnormal response is found to eliminate the fault. When the engine cannot run and traction is required, each steering cylinder should be kept free to move;
7. When shoveling soil (materials), it is not allowed to increase the accelerator and plunge the bucket into the soil (materials) at high speed. Load materials in a pile, use low-speed insertion to place the bottom of the bucket parallel to the ground, then lower the shovel arm, gradually increase the engine speed along the ground to dig forward, and at the same time reel in soil (material) to reduce the resistance encountered by the bucket;
8. When unloading, apply the clutch pedal to brake so that the bucket flips forward without touching the carriage. Unloading should be slow to reduce the impact on the carriage. After the shovel arm moves up or down to the maximum limit, the joystick should be quickly returned to the neutral position to avoid making noise and causing malfunctions of various parts under the action of the safety valve;
9. When walking and turning, you should try your best to When turning slowly, use the brake pedal to slow down, and rolling downhill is strictly prohibited.
