Symptoms

Bezpieczne proste wiertło i czysta praca nie eliminują głośnego dźwięku lub drgań bez obciążenia.
WORKLIGHT COMES ON, BUT THE MOTOR WILL NOT START
A bit that appears clamped slips in use or visibly wobbles in a no-load test.
המקדח/מקדח לא יתחיל עם BATTERY מאומת
The chuck jaws open and close normally, but a straight compatible bit rotates or pulls out during moderate drilling or driving.
Il grilletto si blocca, il trapano continua a girare o la velocità a vuoto salta invece di variare dolcemente.
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 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.
Il battery non scorre, blocca, rilascia o rimane sicuro nell'impugnatura.
The forward/reverse lever binds, commands the wrong direction, or center lock fails.
החבילה לא משלימה טעינה או מספקת זמן ריצה קצר באופן חריג.
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.
A compatible V20 battery starts onto the tool rails but binds before reaching the normal seated and latched position.
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.
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.
ה-battery נשאר נעול פיזית, אך motor, LED או שניהם נכבים וחוזרים כאשר הכלי או battery זזים בכיוון עבודה רגיל.
כאשר battery מוסר והמצמד ריק, סיבוב השרוול מסובב את הציר ו-motor בחופשיות במקום לספק נעילה מספקת להדק או לשחרר את המצמד ביד.
ניתן לשמוע את motor פועל, אך הצ'אק נשאר במקום, עוצר באופן עצמאי או מסתובב חופשי ללא העברת הנעה תקינה בכל טווח מהירות נבחר.
