Setting Upper Blade
Guide Height
When cutting, the blade guides must always be
positioned so they just clear (no more than
1
⁄4")
the workpiece. The guide post, shown in Figure
64, allows the upper blade guide assembly to be
quickly adjusted for height.
To adjust height of upper blade guides:
1. DISCONNECT MACHINE FROM POWER!
2. Loosen guide post lock knob.
3. Use guide post elevation handwheel to adjust
height of guide post so that blade guide
assembly just clears (no more than
1
⁄4")
workpiece.
4. Retighten lock knob to secure setting.
