MOUNTING EXTENSION WINGS
1. Mount the cast iron extension wings using six
1/2-13 x 1-1/4 hex head screws and six 1/2 lock wash-
ers. (These are shipped already inserted into the holes.)
See Figure 2. Have an assistant hold the wing up to
the table, and insert the screws and washers. Finger
tighten only.
NOTE: If an assistant is not available, hold the wing in
vertical position up to the saw table, insert the middle
screw and lock washer finger tight, then pivot the wing
to level position. Insert the other two screws.
2. It is important that the front edge of wing is flush
with front edge of saw table. See Figure 3.
3. Level the extension wing with the table across
its entire width, using a straight edge and hammer
with block of wood (or rubber mallet). See Figure 4.
As each area of the wing becomes flush with the table,
tighten the screw under that area. Continue until all
screws are fully tightened.
4. Repeat for the other wing.
INSTALLING BLADE
NOTE: The blade must be mounted first before rails
can be adjusted. To install or replace a blade, pro-
ceed as follows:
CAUTION: Use care when handling or
working around sharp saw blade.
1. Disconnect machine from power source.
2. Remove table insert, then remove arbor nut and
collar.
3. Install blade, making sure the cutting teeth at
the top of the blade point toward the front of the saw.
4. Slide the collar on to the arbor and start the ar-
bor nut on the threads. (NOTE: right hand threads -
turn clockwise to tighten). Snug the arbor nut against
the collar and blade with the provided arbor wrench,
while holding blade with thumb and finger tips.
5. Wedge a block of wood between the blade and
table to prevent blade rotation, then tighten the arbor
nut securely with the wrench. See Figure 5.
