ASSEMBLY
INSTALLING THE BLAdE
See Figure 23 - 24.
The blade and blade wrenches are located on the side of
the saw in the storage area. Twist the knob counterclockwise
to remove it.
 Remove the blade and two blade wrenches.
 Loosen the height adjusting handwheel lock knob and
turn the handwheel clockwise to raise the blade arbor.
 Place the new blade on the arbor shaft (blade teeth must
point down toward the front of the saw to work properly).
 Place the blade washer and the blade nut over the arbor
shaft. Be sure the dome side of the blade washer faces
out from the blade and that all items are snug against
the arbor housing. Make sure the blade nut is securely
tightened. Do not overtighten.
 Using the open end blade wrench, place the flat open
end into the flats on the arbor shaft.
 Insert the closed end of the other blade wrench over the
hex nut. Holding both wrenches firmly, push the closed
end wrench to the back of the machine. Make sure the
blade nut is securely tightened. Do not overtighten.
 Rotate the blade by hand to make sure it turns freely.
 Lower the saw blade and install the throat plate.
