Daily Maintenance Checks
Perform the following daily maintenance checks to keep
the equipment in good operating condition.
• Ensure proper pivot group adjustment.
• Check blades, guide block and piercing tip for
excess wear. Rotate or replace as needed.
• Inspect jaw for wear, including the chin where the
piercing tip meets the lower jaw. Perform build-up
and hard-surfacing as needed.
Piercing Tip
Proper maintenance of the piercing tip boosts productiv-
ity and prevents material jams. Inspect the piercing tip
daily for wear and perform maintenance every 20-40
hours, depending on the application.
Slowly cycle the shear until the piercing tip is flush with
the top edge of the chin.
Check the gap with a tape measure. Acceptable gap is
1/4” – 3/8” (6 - 9.5 mm)
Check the condition of the piercing tip with a straight
edge or square. Check the profile along the blades.
If the piercing tip is only slightly worn, it can be built up
following the build-up and hard-surfacing procedure in
this manual. When the tip is severely worn, it must be
replaced.
Piercing Tip Replacement
Important:
Remove the upper secondary blade and up-
per wear plate during this procedure to prevent damage.
Preheat the tip area to 350° F (177° C), six to eight inch-
es around the tip. Maintain this temperature throughout
the procedure. Do not exceed 400° F interpass tempera-
ture.
Air arc to remove the piercing tip. Clean the pocket and
chamfer the perimeter at ½” x 45° angles.
Position and tack the new piercing tip in place, square
with the blades and new wear plate.
