Carriage Track, Wiper & Scrapers
WARNING!
Before performing service near moving parts
such as blades, pulleys, motors, belts and chains, first turn
the key switch to the OFF (#0) position and remove the key.
If the key is turned on and moving parts activated, serious
injury may result.
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 5-5.
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. 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.
Clean and lubricate the felt track wiper. Unbolt the middle track cover, remove from the
sawmill and remove any sawdust buildup. Soak the felt wiper with Dexron III transmission
fluid.
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.
LT30 Super Rev. H3.00+ & LT40 Super Rev. H4.00+ only:
Soak the lower felt wipers
with Dexron III transmission fluid. Apply oil to both wipers through the access holes in the
wiper housings.
