Thickness Stop
The thickness stop stops the cutterhead assembly at
To use the thickness stop:
1.Rotate the thickness stop knob to the desired setting (Figure 16).

Figure 16. Thickness Stop Knob.
2.Plane the board, pass by pass, lowering the cutterhead with each pass until the cutterhead assembly reaches the thickness stop and no longer lowers.
Note: The thickness stop should only be used for approximate measurements. If pre- cise workpiece thicknesses are needed, use calipers to ensure your workpieces meet your standards.
Cutterhead Elevation Scale
The cutterhead elevation scale displays the dis- tance between the cutterhead knives (at their lowest points) and the platen. This represents the workpiece thickness produced after the planing pass is made (Figure 17).

Example: If you need to plane a board down to 9⁄16", simply make multiple passes (no greater than the maximum depth-of-cut) until the cutterhead elevation scale reads 9⁄16". A final pass at this set- ting will create a 9⁄16" thick workpiece.
Note: The cutterhead elevation scale does not provide a precise measurement and should only be used for approximate measurements. If precise workpiece thicknesses are needed, use calipers to ensure your workpieces meet your standards.
Elevation Lock
To ensure that the cutterhead assembly does not move during planing, the Model G0689 is equipped with an elevation lock.
To use the elevation lock, set the cutterhead assembly to the desired elevation, then lower the elevation lock lever. To release the lock, lift the lever (Figure 18).
