3.2 Blade Guides
1. Check the rollers for performance and wear every blade change. Make sure the rollers
are clean and spinning freely. If not, rebuild them. Replace any rollers which have worn
smooth or have become cone shaped. See The LT40S/M DH Parts manual for blade
guide rebuild kits and complete roller assemblies.
See Figure 3-1.
2. 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 maintain 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 top rail cover.
CAUTION! Failure to remove sawdust buildup from track
rail cover could result in damage to these parts when the
saw head is lowered to its lowest position.
4. As required, remove sawdust buildup from the power feed belt housing. Turn the control
panel key switch to OFF (0) and remove the key. Disassemble the power feed belt cover
and remove sawdust buildup in and around the power feed belt and pulleys. Replace the
power feed belt cover.
