Troubleshooting & Repair
4.Using leather work gloves to protect your hands from sharp edges, carefully rotate the rotor counterclock- wise until the first worn hammer is at the top position.
5.Before proceeding, note the assembly sequence of the hammer, spacer, spacer tube, and hardware. Hammers and spacers must be reassembled in the same order to ensure proper rotor balance, shredding efficiency, and safety. See Figure 20 for correct posi- tion of parts.
6.See Figure 20. Using a 5/16” Allen wrench, remove the socket head capscrew (A), lockwasher (B), flat washer (C), and spacer tube (D), being careful to catch the parts as the capscrew is removed.
7.Wipe the hammer and spacer tube clean, and inspect for excessive wear.
•If the spacer tube has light grooves worn into it, the tube may be reused by flipping its position over when reinstalling it.
