How to use the automatic BU-tap-to-ground function of the A40DCGUZ350B01 Brush Cutter to release the trimming line? Posted by : admin / Posted on : May 23,2025

When using the A40DCGUZ350B01 Brush Cutter, the automatic BU ground-knocking function is a very practical design that helps users easily release the trimming line and ensures that the device always maintains the best cutting effect during use.

1. Make sure the device is turned off
Before starting the operation, make sure that the A40DCGUZ350B01 Brush Cutter is completely turned off. Avoid accidentally starting the device during operation, causing unnecessary injuries or damage to the device.

2. Adjust the handle angle
Use the handle lock knob to adjust the handle to a comfortable operating angle. This ensures that the operator can maintain good control and balance when tapping the ground, and release the trimming line more effectively.

3. Prepare to tap the ground
Aim the trimming head part of the device at the ground and make sure that the trimming head is perpendicular to the ground. This ensures that when tapping the ground, the force can be evenly transferred to the trimming line to achieve the best release effect.

4. Perform the tapping action
Gently but forcefully tap the trimming head part on the ground. During the tapping process, you can feel the trimming line being gradually released. A certain force and frequency are required to ensure that the trimming line can be fully released, but at the same time, excessive tapping should be avoided to avoid damage to the equipment.

5. Check the release of the trimming line
After tapping the ground, check the release of the trimming line. If the trimming line has been fully released, you can start using the equipment for trimming. If the trimming line is not released enough, repeat the above tapping action until the trimming line reaches the required length.
