Symptoms

Trigger binds, fails to return, changes speed erratically, or does not stop the drive.
The trigger returns normally and power drops, but the anvil repeatedly coasts instead of stopping promptly.
The blade turns steadily, but wood cuts slowly, burns, or needs heavy feed pressure.
The saw or pack smokes, leaks, sparks, melts, smells burned, swells, vents, or hisses.
The external structure is visibly cracked, loose, crushed, melted, or missing material even if the saw still runs.
The motor can be heard, but the front output remains still in both directions with the bit removed.
The direction lever will not reach forward, reverse, or center lock, or the selected position does not hold.
The front hand guard, front or rear handle, main housing, ribbed bumper, fastener, battery well, or another external part is cracked, loose, or missing.
The guide bar cannot be withdrawn from the kerf, the chain is trapped, or the workpiece closes on the saw.
The lithium battery or charger shows abnormal heat, swelling, cracking, electrolyte, hissing, odor, sparks, or smoke.
The saw makes new grinding, clacking, rattling, or strong vibration during no-load running or cutting.
