If the Cut-Off Wheel (56) does not cut all the way through the workpiece, raise the Saw and release the Trigger Lock/Switch (103). Unplug the unit. Wait until the unit comes to a full stop. Remove the workpiece. Set the depth adjustment to a deeper setting (see Setting Depth Adjustment on page 12). After adjusting the depth, bring the Saw all the way down to make sure the Cut-Off Wheel (56) doesn’t contact the Base (13). If it does contact any part of the Base (13), re- adjust the depth so it doesn’t.

5.Repeat the cutting process starting with number 1 above.
