Grabber Blade Replacement
The grabber blade will need to be replaced if it is damaged due to a machine or operator error. It should
be replaced anytime the blade is nicked, bent or damaged in any manner. Damage to the grabber blade
usually occurs because the path of the grabber blade is obstructed, the grabber assembly is not properly
adjusted, or the screws are loosened or not properly torqued.
Parts Needed for Repair:
• Grabber Blade
•
Four (4) M3x6mm flat head slotted screws

Remove the four M3x6mm flat head screws on the bottom of the grabber blade and throw them
away. It is recommended that you do not reuse the screws.

position, starting all four screws loose. Tighten them to the torque specifications when all of the
screws are started.
3. Loosen the four M3x6mm button head screws on the back of the lower trap assembly.
4. With the machine tuned off, move the grabber blade by hand between the upper and lower trap
assemblies and check the horizontal and vertical alignment.
