Removing and Installing Blades
Blade tips can cause personal injury.
REMOVING BLADE
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.
2.
Rotate Lower Blade Guard until there is a clear
access to the Blade Bolt (Fig. 4).
3.
Press and hold the arbor lock (red button on oppo-
site 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.
4.
Using the 6/4mm hex key, loosen the blade bolt by
firmly turning it clockwise. NOTE: This bolt has left-
hand threads.
5.
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).
INSTALLING 12" (305mm) BLADE
12" diameter and 1" (25.4mm) arbor. The blade's
maximum plate thickness is 0.100" (2.54mm).
(RPM) or greater.
1.
Follow all "Moving Guard Assembly" and "Removing
Blade" steps.
2.
Carefully handle the new blade. Check that the rota-
tion 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 Fig. 4 and
5).
3.
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.
4.
Rotate the blade slowly while pressing the arbor lock
until it fully seats into its lock position.
5.
Using the 6/4mm hex key, firmly tighten the blade
bolt counterclockwise. NOTE: This bolt has left-
hand threads. Do not over tighten. A 6mm hex key
may be used as an alternate.
