WARNING! Keep clear of exiting sawdust. Keep hands, feet and any other
objects away from the sawdust chute when operating sawmill. Failure to follow
this may result in serious injury.
WARNING! Ensure the steel fingers inside the sawdust chute are in place
before operating the sawmill. The steel fingers have been designed to help
prevent a broken blade or some other object from becoming a projectile and
exiting the sawdust chute. Failure to have these fingers in place may result in
serious injury.
Remove sawdust buildup from rope feed pulleys and up/down chain sprockets as necessary.
3.4 Carriage Track, Wiper & Scrapers
WARNING! Before performing service near moving parts such as blades, pul-
leys, motors, belts and chains, first turn the key switch to the OFF (#0) position
and remove the key. Failure to follow this may result in serious injury or death.
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 feed movement.
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. Lubrication will help pro-
tect 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.
Clean and lubricate the felt track wipers. Unbolt the middle track cover and idle track wipers,
remove from the sawmill and remove any sawdust buildup. Soak the felt wiper with Dexron III
transmission fluid.
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 screw.
