• Remove round cover plate from behind belt guard.
• Remove the top plate.
• Remove shredder hopper.
• Turn rotor assembly until hammer rod is facing up.
• Turn hammer rod until small end of groove pin is facing up.
• Drive the groove pin from the hammer rod with a punch.
• Remove hammer rod through access hole on side of machine.
• Reverse hammers and reinstall with spacers on hammer rod.
• Replace old groove pin with new groove pin.

NOTE: Be sure the hammers and spacers are reinstalled in exactly the order in which they were removed.
Refer to the rotor assembly drawing for the correct order.
