1. Position the saw in the UP position and at 0°
bevel. If in the DOWN position, press down
slightly on the
the head assembly lock pin (item 43, page 9); then
allow the saw head to come up (see Figure 3).
2. Unscrew the link knob (item 28, page 9) by hand
from the pivot post and allow the link assembly to
hang. The link knob will stay on the link.
3. Loosen front cover plate screw two turns using the
6/4mm hex key. Do not remove screw. A 4mm hex
key may be used as an alternate.
4. Loosen rear plate screw six full turns using the
6/4mm hex key. Do not remove screw.
5. Slide the cover plate down and out from the rear
screw. Rotate the cover plate and lower guard
counterclockwise around the front screw. While
holding the lower guard up against the upper
guard, move the link so its round hole can go over
the rear screw – let go and the lower guard assem-
bly will be held out of the way (see Figure 4).
