Moving Guard Assembly
1. Position the saw in the UP position and at 0°
bevel. If in the DOWN position, press down
slightly on the saw head assembly and pull
out the head assembly lock pin (item 43,
page 12); then allow the saw head to come
up (see Figure 3).
2. Unscrew the link knob (item 28, page 11) 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 al-
ternate.
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).
Removing Blade
1.Press and hold the arbor lock (red button on
opposite side of upper guard – item 42, page
12). Rotate the blade slowly while pressing
the arbor lock until it fully seats into its lock
position.
2.Using the 6/4mm hex key, loosen the blade
bolt by firmly turning it clockwise. NOTE:
This bolt has left-hand threads.
3. Remove the blade bolt and outer washer.
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).
