Symptoms

THE DRILL WILL NOT START WITH A CHARGED KNOWN-GOOD BATTERY
The drill works at no load but stalls, slows severely, or stops during drilling or driving.
The trigger binds, the drill runs on, or no-load speed jumps instead of varying smoothly.
The front work light stays dark during trigger use or remains on abnormally afterward.
Il grilletto si blocca, il trapano continua a girare o la velocità a vuoto salta invece di variare dolcemente.
The forward/reverse lever binds, commands the wrong direction, or center lock fails.
The motor can be heard, but the front output remains still in both directions with the bit removed.
The motor runs normally, but the LED is dead, dim, or intermittent with trigger use.
The bit passed initial insertion, but backs out, falls free, or loses drive while the chuck body stays secure.
The trigger returns normally and power drops, but the anvil repeatedly coasts instead of stopping promptly.
The bit rotates, but no impact pulses begin when a correct fastener provides normal resistance.
The tool or pack smokes, leaks, swells, smells burned, overheats severely, or exposes wiring.
Il trapano non dà risposta di motor, mandrino o luce da lavoro con un battery carico e funzionante.
The chuck coasts much longer than normal after the trigger is released.
A bit that appears clamped slips in use or visibly wobbles in a no-load test.
ניתן לשמוע את motor, אך הצ'אק נשאר במקום או מסתובב רק מדי פעם.
החבילה לא משלימה טעינה או מספקת זמן ריצה קצר באופן חריג.
Il battery non scorre, blocca, rilascia o rimane sicuro nell'impugnatura.
The collar pulls, but the bit will not come out, or a short/broken piece is recessed in the chuck.
The direction lever will not reach forward, reverse, or center lock, or the selected position does not hold.
