The upper jaw has two areas that must be built up so that they are flush with the upper blades, shown in Figure 31.

Lower Jaw
The lower jaw has a number of places that must be built up if worn, as shown in Figure 32. Pay particular attention to
the areas around the lower and guide blades, as those areas must be flush with the blade. Use the included guide blade
build up template to ensure the build up profile is correct. The lower shear must be grounded when welding to prevent
the possibility of electric shock.

Hardsurfacing Recommendations
Some attachments have hardsurfacing instead wear bars or plates. Hardsurfacing must be inspected and maintained.
For hardsurfacing, LaBounty recommends;
•
Amalloy 814H or equivalent
If you have questions about what hardsurface material to use, contact LaBounty Customer Service at 1-(800) 522-
5059.
•
Always use hardsurfacing weld material with a chromium content of less than 0.10% and a severe impact-
resistance rating, to prevent cracking.
•
Apply hardsurfacing directly on top of build up welds. Do not apply hardsurfacing to parent material.
•
Remove paint from the area before hardsurfacing.
