6. Precautions
1. This product isBrushless bare device version, without battery or chargerPlease use a 21V Dewei interface lithium battery by yourself; confirm the compatible battery model before placing your order.
2. When performing the task, do not forcefully turn the screw beyond the 50 N·m limit torque to prevent thread stripping, breakage of the screw, or damage to the internal gears of the tool.
3. Use only in dry, dry-cleaned environments, and away from water accumulation or flammable/explosive conditions to prevent electrical leakage and short circuits that could cause safety hazards.
4. Before replacing the sleeve or maintenance tools, be sure to disconnect the battery power supply to avoid operating while energized and prevent injury from accidental activation.
5. During the task, do not touch the rotating parts of the ratchet; wear protective equipment to avoid personal injury caused by debris or rotating components.
6. Avoid prolonged continuous idle operation to prevent brushless motors from overheating due to continuous no-load operation, which may affect the motor’s service life.
7. After completing the assignment, promptly clean the oil and dust from the device body, and store it in a dry and well-ventilated place. If left unused for a long time, remove the battery and store it separately.
8. If the device produces abnormal noises, stalls, or excessive heat, it must be stopped immediately. Forced operation is prohibited. Non-professionals should not disassemble or modify the device without authorization.
