10 Winter Sawing Tips
BLADE CORNER
1. Lower blade hook angles work better in frozen and partially frozen logs. Consider running 9°, Turbo 7, Turbo 747, or 4° blades 2. Narrow blade widths can have less resistance and effectively clean out frozen sawdust. Consider running 1-1/4" wide blades 3. Pay attention to partially frozen logs as the outside of the log freezes and thaws first 4. Keep feed rates up and consistent to reduce sawdust freezing on material 5. Monitor blade guides to ensure they are tight and level 6. Switch drive and idle side blade wheel belts 7. Check the blade guide arm to ensure it is tight 8. Use proper or slightly higher blade tension 9. Monitor drive belt tension to ensure it is tight 10. Use windshield washer fluid in blade water lubrication tank while sawing in 32° or below temperatures

Tips from the Saw Filers Corner If you are maintaining your own sawmill blades with Wood-Mizer blade sharpeners and tooth setters, here are a few tips from our ReSharp® blade sharpening specialists to ensure you receive consistent, sharp, and accurate blades with each sharpening. First make sure your blade maintenance equipment is cleaned thoroughly and inspect all electrical cords for damage. Second, inspect the blade for any teeth damage and begin with as clean of blade as possible by lubricating the blade before removing from your sawmill equipment to eliminate any pitch build-up or wash the blade before installing on your maintenance equipment.
WINTER SAWING FAQ
HELPFUL BLADE MAINTENANCE TOOLS Red Layout Dye (Part # 057791) is used to mark the profile of a blade on the tooth face, gullet, and back to ensure proper grinding depth and indexing while resharpening. Blade Profile Gauge (Part # 109064) includes a total of 15 profiles to determine the correct blade profile before sharpening. Tooth Setter Gauge (Part # 060490) is used to measure tooth set quickly and accurately for the best quality control.
