Sawdust Removal
1.
Remove the excess sawdust from the blade wheel housings and sawdust chute every blade change.
2.
Remove all sawdust and debris from around the velocity fuse valves every 8 hours of operation. The valves
are located at the bottom of the log loader cylinders. Remove sawdust buildup as necessary from the battery
box lid and top rail cover.Remove sawdust buildup as necessary from the rail cover.
Failure to remove sawdust buildup from the battery box lid and/or track rail cover could result in damage to
these parts when the saw head is lowered to its lowest position.

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 3-3.
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 particles 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 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.
Clean and lubricate the upper track wiper every twenty-five hours of operation. Unbolt the wiper, remove
itfrom 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.
