4.
Make sure the blade screw in the top center of the C-frame is 1/16" (1.5 mm) below the bottom of the blade. If
not, loosen the nut and adjust the screw as necessary. Check the screw every blade change. Failing to main-
tain this adjustment will lead to early blade breakage.
3.3
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.
3.
Remove sawdust buildup as necessary from the battery box lid and top rail cover.
CAUTION!
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.
3.4
Carriage Track, Wiper & Scrapers
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.
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.
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.
