After lockout tagout and access has been obtained to the assemblies, follow these instructions to
remove and replace the router bit or the pre-drill bit.
FIGURE 3-21.
Removing Pre-Drill or Router Bit.
1.
Use a 17 mm shaft wrench and a 3/8 “collet wrench to remove the bit on the pre-drill
or router assemblies.See Figure below.
2.
Lightly attach collet assembly on to drill.
3.
Insert the new bit into the assembly.
4.
Before tightening the collet assembly, adjust the bit depth. Set the router bit to
1 3/4 “and the drill bit to 2.0” from the base of the collet nut to the tip of the bit. If
available, use the Router Bit Depth Gauge (PN 432 C) to set the depth of the drill.
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.
5.
Tighten the collet assembly.
