!WARNING To avoid injury, do not use a blade larger or smaller than 812"

diameter and 5/8" arbor. The blade’s maximum plate thickness is 0.070".

To reduce risk of injury, use saw blade rated 5600/min (RpM) or greater.

1.Carefully handle the new blade. Check that the rotation arrow on the blade matches the rotation arrow on the lower guard. Slide the blade up and between the sides of the chip deflector and over the arbor shaft. Move the blade so its arbor hole goes around the support ring of the inner washer (see figures 3 and 4).

2.Place the outer washer over the arbor shaft and finger-tighten the blade bolt (counterclockwise). Check that the blade remained on the inner washer’s support ring.

3.Rotate the blade slowly while pressing the arbor lock until it fully seats into its lock position.

4.Using the 5mm hex key, firmly tighten the blade bolt counterclockwise. NOTE: This bolt has left- hand threads. Do not over tighten.

5.Be sure the arbor lock is released so the blade turns freely.

6.Place the 5mm hex key back in storage area.

7.Raise the blade bolt cover plate and screw into place using the provided hex wrench.

After installing a new blade, make sure the blade does not interfere with the table insert at 0° and 45° bevel

positions. lower the blade into the blade slot and check for any contact with the base or turntable structure. If the blade contacts base or table, seek authorized service.
