6. Precautions
1. This tool is designed for 21V lithium battery models; it must be used with a 21V lithium battery of the corresponding specification. Mixing batteries with incorrect voltage is prohibited to prevent damage to the motor and circuits.
2. It is strictly prohibited to use a maximum torque of 50 N·m to tighten the screws forcibly, to prevent bolt breakage, thread stripping, or damage to the internal gears and movement structure.
3. Work is prohibited in rainy conditions, damp waterlogged areas, or flammable and explosive environments to prevent electrical leakage and short circuits that could cause equipment failure and safety incidents.
4. Before replacing the sleeve, performing maintenance, or storing tools, it is essential to disconnect the battery power supply. Avoid operating with electricity to prevent accidental activation of the equipment that may cause personal injury.
5. Do not touch the ratchet rotating head during operation. It is recommended to wear protective equipment to prevent injury from iron filings and rotating parts.
6. Avoid prolonged continuous idle operation; running without load can lead to motor overheating and wear. Intermittent shutdown for heat dissipation can effectively extend the motor's service life.
7. After completing the assignment, promptly clean the oil and dust from the device surface, and store it in a dry and well-ventilated place. If not used for a long time, remove the battery and store it separately.
8. If the device exhibits abnormal noises, stuttering, excessive heat generation, or reduced performance, it must be stopped immediately. Forceful operation is prohibited. Non-professionals should not disassemble or modify the device without authorization to avoid losing warranty coverage.
