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.
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.
2.
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 lower step or housing.
3.
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.
4.
As the blocks wear, the front inside corner will wear more than the body of the block.
When the corner wears far enough, sawing performance will be affected even if the body
of the block is adjusted properly to the blade. At this point, the block should be replaced.
If you have access to the appropriate equipment, you can grind or mill the blocks to a new
flat surface and reuse them. It is recommended you develop a routine schedule for
replacing the blade guide blocks based on your sawing conditions and experience.
To adjust the top block down, loosen the clamp bolt and mounting bolt. Turn the adjust-
ment bolt clockwise. Retighten the mounting bolt and clamp bolt.
To adjust the bottom block up, loosen the clamp bolt and mounting bolt. Use the provided
adjustment tool to turn the adjustment screw clockwise. Retighten the mounting bolt and
clamp bolt.
IMPORTANT!
The blocks should be parallel to the blade.
for instructions about checking and adjusting the assembly level
with the blade.
