High-quality carbon brushes made from material designed for the C8FSE C8FSHE Slide Compound Miter Saw 999-021 Improved motor performance: worn brushes can cause poor motor operation, but replacing them can resolve intermittent motor issues and restore electrical braking Common spare part: carbon brushes are the most frequently replaced power tool component due to wear from friction and use Check for motor damage: when replacing the brushes, inspect the armature for burns, cracks or other damage that could indicate a larger motor problem Use scenarios - Routine maintenance in a woodworking shop to keep the C8FSE/C8FSHE saw operating smoothly - After signs of intermittent motor behavior or reduced braking during cutting tasks - On job sites during scheduled maintenance to ensure reliable cutting performance
