Blade Guides
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.
1.
For mills equipped with greaseable blade guides, lubricate the blade guide rollers every
four hours of operation. Use one squeeze of a NLGI No. 2 grade lithium grease from a
grease gun to lubricate the bearings and remove any sawdust.
See Figure 5-1.
CAUTION!
Do not over-grease the blade guide bearings.
Over-greasing will push the seals out of the bearings caus-
ing premature failure.
2.
Check the rollers for performance and wear every blade change. Make sure the rollers
are clean and spinning freely. If not, replace them. Replace any rollers which have worn
smooth or have become cone shaped.
EZ-Glide Guide Blocks
3.
Inspect the blocks at every blade change for damage or wear. If the block housing is bent
or damaged, replace the block assembly. Also, replace the block assemblies before the
blocks are worn to a point the blade may contact the block housing.
4.
Check the guide blocks are properly spaced from the blade every 25 hours of operation.
Use the provided shim or a feeler gauge to check the blocks are adjusted .008” - .010”
from the blade.
