SHEAR JAW
Measuring Primary / Secondary Blade Gap and Shimming
Note: Removing and handling blades can be hazardous if done incorrectly.
Stay at least 75 ft. (23 m) when moving.
1. Cycle the tool until the upper jaw blade begins to overlap the lower jaw blade.
2. Measure the blade gap. If the gap is larger than 0.4 mm, add shims between the guide blade and blade seat until the
gap is 0.4 mm.
Measuring Guide Blade Gap and Shimming
Note: Removing and handling blades can be hazardous if done incorrectly.
Stay at least 75 ft. (23 m) when moving.
1. Slowly close the jaws until the tip blade meets the guide blade.
2. Measure the gap between the tip blade and guide blade. This gap should never exceed 0.4 mm.
3. If the gap is larger than 0.4 mm, remove the guide blade and insert shims until the gap is within 0.4 mm.
4. If you are unable to shim the blade within the 0.4 mm gap measurement, you must rotate the blade.
Measuring Cross Blade Gap and Shimming
Note: Removing and handling blades can be hazardous if done incorrectly.
Stay at least 75 ft. (23 m) when moving.
1. Slowly close the jaws until the tip blade meets the cross blade.
2. Measure the gap between the tip blade and cross blade. This gap should never exceed 0.4 mm
3. If the gap is larger than 0.4 mm, remove the cross blade and insert shims until the gap is within 0.4 mm.
4. If you are unable to shim the blade within the 0.4 mm gap measurement, you must rotate the blade.
Primary/Secondary Blade Rotation
Each shear jaw blade has four edges. Each time you rotate the blade, use a different edge until all the edges are
worn to .25” radius.
