FM-21: 零度切割唔係材料嘅直角

斜角指針設為零，鞋板睇落平，但完成嘅切割持續唔係工作面嘅90度。

• Zero-degree shoe calibration is out of adjustment
• Bevel lever is not fully locked or shoe moves during the cut
• Blade is bent, loose, or side-loaded
• Shoe is bent, dirty, or not resting flat on the work

1. An actual zero-bevel scrap cut measures square through the material and the locked setting repeats.

1. Release the trigger, wait for a full stop, remove the battery, set bevel to zero, and clean the shoe/blade reference surfaces.
2. Confirm a straight correctly clamped blade, a flat undamaged shoe, and a bevel lever that locks without movement.
3. Retract the lower guard with the battery removed, place the saw on its blade side, and compare the blade plate - not a tooth - to an accurate square agains
4. Adjust only the accessible 90-degree calibration screw by the official procedure, relock the bevel lever, and return the guard to normal operation.
5. - Make and square-check an actual supported scrap cut - if the setting will not calibrate or hold, stop and route the shoe, quadrant, pivot, and spindle align
