bolt (4). (Fig. F)

holding it in rmly while turning the

blade wrench counterclockwise.

Continue to press the arbor lock

button while tightening the arbor

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. F)

NOTE: The lower blade guard must

be raised to the upright position to

access the cover plate screw.

6. Lower the blade guard (1) back to

its original position. (Fig. F)

and up several times to conrm the

lower blade guard operates without

released so the blade turns freely

● To avoid injury, never use the

saw without the cover plate

secure in place. It keeps the

arbor 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 saw table.
