FM-22: 斜角无法设置、锁定、保持或正确读取

底板无法按预期范围倾斜，斜角杆无法夹紧，切割时角度滑动，或指针/刻度盘无法提供可重复角度。

• Sawdust is packed at the pivot, quadrant, pointer, or lever
• Lever is loose, stripped, cracked, or incorrectly positioned
• Shoe, pivot, quadrant, or pointer is bent or worn
• Zero calibration or angle reading is being confused with a general locking failure

1. The shoe sets within its range, locks firmly without movement, and produces a repeatable verified bevel angle.

1. Remove the battery and set the saw on a stable surface before touching the bevel lever or shoe.
2. Clean the exposed pivot, quadrant, pointer, and lever dry, then inspect for cracks, bend, missing hardware, or a lever that cannot clamp.
3. Loosen the lever counterclockwise, tilt the shoe to the desired marked angle within 0-57 degrees, and retighten the lever clockwise firmly.
4. - Check for movement by hand and confirm the angle with a gauge or a controlled scrap cut - use FM-21 only for a zero-degree calibration error.
5. If the shoe cannot move, lock, hold, or read repeatably, keep the saw out of service for authorized lever, pivot, quadrant, pointer, and shoe repair.
