Installing Blade (Fig. G, H, I)
1. Install a 10 in. blade with a 5/8 in. arbour making sure the
rotation arrow on the blade matches the clockwise rotation
arrow on the upper guard, and the blade teeth are pointing
downward.
2. Place the blade collar (6) against the blade and on the
arbour. Thread the arbour bolt (4) onto the arbour in a
counterclockwise direction. (Fig. G) IMPORTANT: Make
sure the flats of the blade collars are engaged with the
flats on the arbour shaft. Also, the flat side of the blade
collar must be placed against the blade.
3. Place the blade wrench on the arbour bolt.
4. Press the arbour lock (5), holding it in firmly while turning
the blade counterclockwise. When arbour lock engages,
continue to press it in while tightening the arbour bolt
securely. (Fig. H)
5. Rotate the cover plate (3) back to its original position until
the slot in the cover plate engages with the cover plate
screw (2). While holding the lower blade guard, tighten the
screw with a Phillips screwdriver. (Fig. G)
NOTE: The lower blade guard must be raised to the upright
position to access the cover plate screw.
6. Lower the blade guard (1) and verify that the operation of
the guard does not bind or stick.
7. Be sure the arbour lock is released so the blade turns freely.
WARNING
• To avoid injury, never use the saw without
the cover plate secure in place. It keeps the arbour bolt
from falling out if it accidentally loosens, and helps
prevent the spinning blade from coming off the saw.
• Make sure the collars are clean and properly arranged.
Lower the blade into the table and check for any contact
with the metal base or the turn table.

2. Lower the cutting arm and lock in position.
3. Using a square, lay the heel of the square against the blade,
and the rule agaist the fence(2) as shown. Check to see if
the fence is 90° to the blade.

locking bolts. CAUTION: If the saw has not been used
recently, recheck blade squareness to the fence and
readjust if needed.

piece. Readjust if
