Common symptoms
- A charged, latched battery and normal trigger command produce no chuck rotation.
- The battery will not slide fully into the handle, stay retained, or release normally.
- The pack will not charge, or the charger light stays off or shows an abnormal red pattern.
- The cool drill begins to run, then stops during a brief no-load test or light work.
- The trigger binds, fails to return, starts unpredictably, or no-load speed surges.
- Forward or reverse will not engage, or the center position will not lock the trigger.
- The collar will not align or hold, or screwdriving clutch cut-off is absent or premature.
- The chuck sleeve will not turn enough to move the jaws or admit a normal straight bit.
- The chuck opens and closes, but the bit slips, pulls out, or ejects during normal work.
