Installing 12" Blade

!WARNING To avoid injury, do not use a blade larger or smaller than 12"

diameter and 1" arbor. The blade’s maximum plate thickness is 0.100".

! WARNING

To reduce risk of injury, use saw

 

blade rated 4300/min (RpM) or

greater.

 

1.Follow all “Moving Guard Assembly” and “Remov- ing Blade” steps.

2.Carefully handle the new blade. Check that the rotation arrow on the blade matches the rotation arrow on the upper guard (see Figure 5). 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 Figure 6).
