Assembly
Installation And Removal Of The Blade
Disconnect plug from power source
before performing any assembly,
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 #40 on page 9) while turning bolt clockwise
using the multi purpose tool.
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.
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 tight-
en 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 interfere
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 autho-
rized service.
