GUIDE BLADE SHIMMING
AND ROTATION
continued
5.
The guide blade can be rotated once so the whole
face of the blade can be used to increase its life.
When it is time to rotate the blade, remove it and
turn it end for end, and place it back in its seat. The
same face should be used for the entire life of the
blade. Use the steps above to shim the guide blade
to the correct gap. When the whole face of the
blade is worn and it cannot be shimmed any more,
replace it with a new one.
6.
If a gap greater than 0.030" (0.76 mm) still exists
with a new guide blade and a full set of shims, the
Saber Tip will need to be replaced. Refer to the Cut-
ting Blade Rotation procedure in this section.
7.
When the gap is correct, apply the correct torque
to all of the guide blade bolts. Refer to the BLS
shear Blade Bolt Torque Chart of page 5-10 of this
manual for the proper torque values.
EXAMPLE
Recorded
Gaps 0.035”
0.040”
0.045”
Smallest Gap
0.035”
Minus Desired Gap
0.010”
Shim Amount Needed
0.025”
For this example, one of the 0.024” (0.61 mm)
thick shim would be used achieve the desired
guide blade gap.
