Moving Guard Assembly
1. Position the saw in the UP position and at 0°

hand from the pivot post and allow the link
assembly to hang. The link knob will stay on
the link.

5. Slide the cover plate down and out from the
rear screw. Rotate the cover plate and lower
guard counterclockwise around the front

and the lower guard assem bly will be held out
of the way (see Figure 4).

Carefully grab the blade. Slide the blade away
from the inner washer and off the arbor shaft,
then down and away from the saw. Leave the
inner washer on the arbor shaft (see Fig. 5).
