Make sure the lip on the spindle is engaged with the notch on
the shaft. Open the front access door and hand tighten the 2
lock nuts and bevel washer on the bottom of the draw bar as
shown in picture. Ensure the bevel washer is put on the draw

WaRninG
The cutter is extremely sharp. Use caution when handling or working
with the cutter.
1. Place the cutter head and spacers onto the spindle. Place the
tool as close to the bottom of the spindle as possible.
2. Attach the keyed washer on the spindle, making sure the
washer engages the grooves on the spindle.
WaRninG
Always place the keyed washer on the spindle before threading on
the nut. The keyed washer prevents the nut from loosening when the
spindle turns in a counterclockwise direction.
3. Be sure that the top retaining nut and top spacer are in
firm contact.
Caution
There must be no gap between the bottom of the retaining nut
and the top of the uppermost spacer. Any gap that exists during
operation could result in significant damage to the spindle.
4. Attach and tighten the nut with all threads engaged using the
provided spindle nut wrench.
5. Disengage the spindle lock as explained in 4.2 Step 6.
Caution
The cutter should be positioned on the spindle so that the cut is
performed from underneath the surface of the workpiece.
WaRninG
After installing or replacing cutters and before operating the
machine, carefully check to ensure that the direction of the cutter
and keyed washer is correct, and that the spindle rings are directly
underneath the spindle nut and securely tightened.
