症状

The motor can be heard, but the front output remains still in both directions with the bit removed.
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.
Motor sound is present, but the anvil and installed bit remain stationary.
The cap will not close, the primer is split or stuck, or the oil-level indicator is cracked, clouded, or leaking.
The cool dry pack has a visibly cracked, missing, loose or distorted rail, release button, latch feature or molded support, whether or not insertion has been attempted.
垫子转动时出现异常驱动接触噪音
充电器在插入或移除battery时摇晃、滑动、从screws上抬起或拉开，尽管后部钥匙孔槽和外壳可见完好。
A compatible V20 battery starts onto the tool rails but binds before reaching the normal seated and latched position.
A straight bit or the empty chuck shows repeatable side-to-side runout at low no-load speed after the bit has been centered and tightened correctly.
battery保持物理卡扣，但motor、LED或两者在工具或battery移动至正常工作姿态时断电并恢复。
The chuck jaws open and close normally, but a straight compatible bit rotates or pulls out during moderate drilling or driving.
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 collar moves and holds a low numbered setting, but the clutch does not ratchet before a test fastener is overdriven in suitable scrap material.
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 direction selector is centered, but the trigger still depresses enough to start the motor or the center position cannot reliably prevent activation.
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.
With the battery removed and the chuck empty, turning the sleeve rotates the spindle and motor freely instead of providing enough lock to tighten or loosen the chuck by hand.
With the battery removed, the keyless chuck sleeve or jaws remain seized, or a clamped bit cannot be released by normal hand rotation.
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.
可听到motor运转声，但卡盘保持静止、独立暂停或空转，未在任一选定速度档传递正常驱动。
