症状

A sound V20 battery is fully seated, the direction button is fully forward or reverse, and the tool gives no motor sound, LED response, or chuck motion. The dead state persists when the tool is held still.
The battery stays physically latched, but the motor, LED, or both cut out and return when the tool or battery is moved through ordinary working orientation.
已裝入充電電池包，但扳機無工作燈、motor聲音或鐵砧動作。
A compatible V20 battery starts onto the tool rails but binds before reaching the normal seated and latched position.
THE DRILL/DRIVER WILL NOT START WITH A VERIFIED BATTERY
The motor can be heard running, but the chuck remains still, pauses independently, or free-spins without transmitting normal drive in either fully selected speed range.
拆除battery並且夾頭空置時，轉動套筒會令主軸同motor自由轉動，而唔係提供足夠鎖力用手緊或鬆夾頭。
With the battery removed, the clutch collar is physically stuck, cracked, excessively loose, or unable to align a numbered setting or drill mode with the index mark.
扳機回彈同motor停止，但LED保持亮起超過大約20秒。
motor同鐵砧正常運行，但LED冇正確照亮即時工作區。
A room-temperature V20 battery is fully seated in a powered approved charger, but normal charging does not begin or the pack never reaches a completed-charge indication.
With the chuck stopped and battery removed, the top selector cannot be moved fully into range 1 or range 2, even after the chuck is turned by hand to align the gears.
工具完全死機 - 無LED或MOTOR
The direction selector is centered, but the trigger still depresses enough to start the motor or the center position cannot reliably prevent activation.
With the battery removed, the keyless chuck sleeve or jaws remain seized, or a clamped bit cannot be released by normal hand rotation.
The chuck still rotates, but a new mechanical grind, knock, scrape, tight spot, or severe vibration remains with the bit removed and is not ordinary motor or brake sound.
The included compatible charger shows no status light and will not begin charging a sound pack.
The chuck jaws open and close normally, but a straight compatible bit rotates or pulls out during moderate drilling or driving.
The collar moves normally, but the clutch ratchets before a suitable fastener reaches normal depth at appropriate settings, or it audibly slips when drill mode is correctly selected.
The drill sounds and rotates normally with no load, does not stall, overheat, slip, or vibrate abnormally, yet a corrected drilling or fastening task progresses much more slowly than expected.
