Carriage Track, Wiper & Scrapers
See Figure 3-3.
1. Clean the upper and lower track rails to remove any sawdust and sap buildup every eight
hours of operation. Lubricate the lower track rail by wiping it with Dexron III ATF.
NOTE: If the top rail is not factory painted, apply a rust inhibitor such as Sherwin-Williams
P.D.R.P #710 when the sawmill is not in use. Use a clean, dry cloth and a light lubricant
such as WD-40 to remove the protection coat before operating the sawmill.
2. Remove sawdust from the upper cam housings. Loosen the thumb screws on the upper
cam housing covers and open. Brush any sawdust buildup from the housings.
3. Check the track scrapers as needed. Make sure the scrapers fit firmly against the rail. If a
track scraper needs to be adjusted, loosen the thumb screw, push the scraper downward
until it fits firmly against the rail, and retighten the thumb screw.
4. Clean and lubricate the track wiper every twenty-five hours of operation. Unbolt the wiper,
remove it from the sawmill, and remove any sawdust buildup. Soak the felt wiper with
Dexron III transmission fluid, 10W30 motor oil or 3-in-1 turbine oil. Replace the wiper.
CAUTION!
Reinstall the wiper so that it lightly touches the
track rail. If the wiper presses too firmly against the rail, it
can cause the power feed to bind.
