5.4 Carriage Track, Wiper & Scrapers
Properly maintaining the sawmill carriage track is critical in preventing corrosion that can
cause pitting and scaling on the rail surfaces. Pitted and scaled surfaces can, in turn,
cause rough cuts or jerky power feed movement.
See Figure 5-3.
1. Clean track rails to remove any sawdust and sap buildup every eight hours of operation.
Use a light-grade sandpaper or emery cloth to sand off any rust or other adhering parti-
cles from the rails.
CAUTION! Keep track rails free of rust. Formation of rust
on the track rail in the areas where the cam bearings roll
can cause rapid deterioration of the track rail's surface.
Lubricate the rails by wiping them with Dexron III ATF transmission fluid, 10W30 motor
oil, or 3-in-1 turbine oil. Oil lubrication will help protect the rails from corrosive elements
such as acid rain and/or moisture from nearby bodies of saltwater (if applicable). This
lubrication is essential to maintain the integrity of the track rails and track rollers and to
achieve long service life.
2. Remove sawdust from the track roller housings and lubricate the felt track wiper every
twenty-five hours of operation.
Remove the track roller housing covers and brush any sawdust buildup from the hous-
ings.
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 screw, push the scraper downward until it
fits firmly against the rail, and retighten the thumb screw.
Clean and lubricate the upper 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.
CAUTION! Reinstall the track 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.
