FM-13: The Saw Or Gearcase Becomes Abnormally Hot Or Smells Hot Without Smoke Or Sparks

The housing, gearcase, battery interface, or motor area heats unusually fast or gives a hot mechanical/electrical odor, but there is no visible smoke, spark, melting, or liquid.

• Vents are blocked by sawdust or the saw is being forced
• Dull, dirty, wrong, or deeply set blade is overloading the motor
• Blade, guard, bearing, or gear drive is dragging
• Battery, motor, electronic module, bearing, or gearcase is failing

1. After correction, one controlled light cut produces normal temperature rise only, with free blade/guard movement and no hot odor.

1. Release the trigger, keep control until the blade stops and guard closes, remove the battery, and let the saw cool in a dry noncombustible area.
2. - Inspect for smoke, sparks, melting, liquid, battery damage, or worsening odor - route those conditions immediately to FM-06 or FM-14.
3. Clean the vents with dry air, correct blade depth and work support, and replace any dull, dirty, damaged, or wrong blade.
4. With the battery removed, hand-turn the blade and check the lower guard for free motion without scrape or drag.
5. - Use a known-good pack for one light supported scrap cut - if rapid heat or hot odor returns, stop and request authorized motor, electronic, bearing, and gea
