BLACK+DECKER BDCR20C Repair Manual

Symptoms

The blade strokes steadily but cuts slowly, stalls easily, or needs excessive feed force.
The drill runs steadily but drills slowly or cannot drive a normal fastener with correct setup.
The blade leaves the line, flexes excessively, bends, or breaks during an otherwise controlled cut.
The clamp lever opens normally, but the installed blade remains trapped in the front clamp.
The Clean Base has no status response or cannot pass charge to the robot.
The 200-series robot is awake nearby, but the iRobot app cannot add or connect to it.
The robot moves, but one wheel makes repeatable noise or feels rough through rotation.
The chuck opens and closes, but the bit slips, pulls out, or ejects during normal work.
The running saw jumps, vibrates against the work, snags, or kicks backward or sideways.
The battery will not insert fully, click into place, remain retained, or release normally.
The robot charges fully, but ends early with low battery, repeatedly recharges, or cannot reach the Home Base before Error 46.
The robot drives and sprays, but the cleaning head lacks its normal scrubbing vibration with a wet pad.
The robot is charged but cannot drive off the Home Base when a job begins after clearance and placement are proven.
The shoe will not pivot freely, is bent or loose, or will not sit firmly against the work.
The tank is filled to the top and installed flat, but the red sweep or Error 37 still says to fill it.
The robot refuses charge because the pack temperature is outside normal range.
The tool-free blade-clamp release lever will not reach full open or close securely.
The charger will not begin or complete charging, or its green light does not behave normally.
The trigger binds, fails to return, starts unpredictably, or no-load speed surges.
A genuine m Series pad is fully seated in both tracks, but the robot refuses to run or selects the wrong pad state.
