Changing Blades

To remove the blade, ensure the power is discon- nected and:

1.Loosen tension on the blade by turning the tension control knob.

2.Remove the table insert and table pin.

3.Remove the fence and front fence rail.

4.Adjust upper guide bearings and lower guide blocks away from the blade.

5.Open the upper and lower wheel covers and slide the blade off both wheels. Use caution, the blades are sharp!

6.Maneuver the blade through the table slot then turn it 90û to move the blade between the fence rail and the table.

To replace the blade, ensure that the power is dis- connected and:

1.Slide the blade behind the fence rail and through the table slot, ensuring that the teeth are pointing down toward the table.

If the teeth will not point downward in any ori- entation, the blade is inside out. See Figure 10 for typical blade geometry. Put on heavy gloves, remove the blade, and twist it until it is right side out. Re-install the blade.

2.Slip the blade through the upper and lower guides and mount over the upper and lower wheels.

3.Apply tension to the blade by turning the tension control knob. Refer to blade ten- sioning instructions earlier in this section.

4.Rotate the upper wheel manually and check blade tracking.

5.Adjust the upper guide bearings and lower guide blocks as described earlier in this section.

6.Close the wheel covers. Turn the yellow guard locking knobs to lock them shut.

7.Replace the table insert and table pin, being sure not to use excessive force.

8.Replace the fence rail and fence.

Use extreme caution when replacing blades. Teeth are dangerously sharp and coiled blades are prone to spring when released from their packaging. Use gloves and safety glasses or goggles whenever handling blades. Failure to do so could result in seri- ous personal injury.
