TOOLING INSTALLATION AND REPLACEMENT
Check diamonds for wear periodically, as they may be worn flush with the holder lugs.
1. Move the counterbalancing weights to the upper weight baskets.
2. Using the flop handle, tilt machine back so that the caster wheel rests on the floor.
3. Clean mounting surface on both the diamond and holder. On 2” or 3” diameter diamond,
push into the hole and twist slightly to be certain it is securely in place.
4. Grasp machine handle and lower machine to the floor slowly so that all diamonds are
resting on the floor. Make certain none have fallen or loosened while lowering the machine
to the floor.
ACCESSING THE DRIVE PLATE, DRIVE KEY, AND GREASE
SEAL
• Remove tool plate and coupling by removing two 3/4” bolts (Figure 15).
• Remove the drive plate by removing 1-7/16” lock nut (Figure 16).
Replacing a Damaged Key
If the drive plate won’t spin, the key is likely damaged. Complete the above steps to gain
access to the key and check for damage (Figure 17). Replace if damaged or contact NFE
