Assembly
Disconnect plug from power
source before performing any as-
sembly, adjustment or repair to avoid possible injury.
1. The miter saw is equipped with a lock pin used
to lock the miter saw in the lowered position. To
release, push the handle down slightly and pull
the lock pin to its full out position and rotate 90°.
NOTE: If there is difficulty in pulling the lock pin
out, you may need to adjust the depth stop bolt
so the handle can be pushed down.
2. Loosen, but do not remove, both cover plate
screws (front and rear). (Figure 1)
3. Lift the lower guard and the cover plate so the
blade bolt is exposed (Figure 1).
4. Remove blade bolt by pressing the arbor lock
(Item #39 on page 9) while turning bolt clockwise
using the (multi purpose tool model 4410) or
(multi purpose “L” wrench model 4310).
NOTE: The blade bolt has left hand threading.
5. Remove the blade bolt, outer washer and the
blade. Do not remove inner washer (Figure 2).
6. Install 10" blade onto the arbor shaft (Figure 3).
NOTE: Make sure the rotation arrow on the
blade matches the clockwise rotation arrow on
the lower guard.
To avoid injury, do not use a
blade larger or smaller than 10"
diameter and 5/8" arbor. Smaller blades will not cut
workpiece all the way through and larger blades will
cut into table and/or blade guards.
To reduce risk of injury, use saw
blade rated 4800/min (RpM) or
greater.
7. Replace the outer washer in it’s proper orientation
and tighten blade bolt finger tight.
8. Press the arbor lock and tighten blade bolt
securely, but do not overtighten.
9. Rotate cover plate to its original position and
tighten both cover plate screws.
Never use saw without cover
plate securely in place. Lower
guard will not function properly.
10. Be sure the arbor lock is released so the blade
turns freely.
After installing a new blade,
make sure the blade does not in-
terfere with the table insert at the 0° and 45°
bevel positions. Lower the blade into the table slot
and check for any contact with the base or turn table
structure. If blade contacts base or table, seek au-
thorized service.
