1. Use the shaft wrench and collet wrench to
remove the bit on the pre-drill or router
assemblies. See photo.
When loosening the collet, it may tighten up,
crack again and continue.
2. Inspect and clean collet assembly.
3. Insert the new bit into the assembly.
4. Before tightening the collet assembly, adjust
the bit depth. Bottom out the bit and pull the bit up about 1.4''.
5. Lightly tighten and torque to correct value. For torque values, Collet Torque Values
Note: Make sure the arbor is not bottomed out in the back of the motor. If it is the arbor
will not tighten and will damage the collet or other machine parts.
