BLACK+DECKER LD120VA Repair Manual

Symptoms

A charged, latched battery and normal trigger command produce no chuck rotation.
Trigger binds, fails to return, changes speed erratically, or does not stop the drive.
The tool, pack, or charger becomes unusually hot, or protection repeatedly stops operation.
BATTERY WILL NOT CHARGE
A secure straight bit and clear work do not eliminate harsh no-load sound or vibration.
A straight bit stays clamped but rotates off-center, or the chuck body has visible play.
Chuck clicks while tightening
The chuck opens and closes, but the bit slips, pulls out, or ejects during normal work.
The cool drill begins to run, then stops during a brief no-load test or light work.
The drill runs steadily but drills slowly or cannot drive a normal fastener with correct setup.
The motor can be heard, but the front output remains still in both directions with the bit removed.
A charged pack is installed, but the trigger produces no worklight, motor sound, or anvil movement.
Charger green LED stays on
The external structure is visibly cracked, loose, crushed, melted, or missing material even if the saw still runs.
The trigger returns normally and power drops, but the anvil repeatedly coasts instead of stopping promptly.
A straight bit traces a visible circle at no load instead of rotating on a stable centerline.
The 360-degree dust port is jammed or loose, or a compatible hose/coupler will not stay attached.
WORKLIGHT COMES ON, BUT THE MOTOR WILL NOT START
The bit jams, the motor stalls, or the drill twists sharply in the hands during work.
The bar is bent or cracked, chain links or cutters are broken, or the guide-bar scabbard is split, missing, or will not stay on.
