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.

screws (front and rear). (Figure 1)

blade bolt is exposed (Figure 1).

workpiece all the way through and larger blades will
cut into table and/or blade guards.
