A charged, latched battery and normal lock-off and trigger command produce no blade stroke.
BATTERY WILL NOT CHARGE
The battery will not slide fully into the handle, stay retained, or release normally.
BATTERY WILL NOT SEAT, LATCH, OR RELEASE
Battery repeatedly overheats or protection-stops during light use
Trigger binds, fails to return, changes speed erratically, or does not stop the drive.
BATTERY SEATS BUT WILL NOT STAY LATCHED
Battery or charger feels warm
A charged, latched battery and normal trigger command produce no chuck rotation.
Chuck clicks while tightening
The chuck opens and closes, but the bit slips, pulls out, or ejects during normal work.
The tool, pack, or charger becomes unusually hot, or protection repeatedly stops operation.
Smoke, flame, arcing, liquid, damaged cord, battery damage, or exposed structure is present.
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.
Clamp lever will not travel
The drill runs steadily but drills slowly or cannot drive a normal fastener with correct setup.
With the clamp lever working, a correct blade will not enter fully or fails the hand tug-check.
The motor can be heard, but the front output remains still in both directions with the bit removed.
The trigger returns normally and power drops, but the anvil repeatedly coasts instead of stopping promptly.
