guard installation & removal
the guard may need to be removed from the
spreader in order to make room to properly adjust
the position of the spreader. the guard is secured
in place with a mounting screw (see
figure 72).
remove the mounting screw to pull the guard off
of the spreader.
When re-installing the guard, the mounting screw
must be left loose enough that the guard can
freely pivot up and down, but not so loose that
there is side-to-side play when pivoting.

testing guard for correct operation
after installing the blade guard, you must verify
that it functions correctly before making a cut. to
test the blade guard operation, lift up the front end
about 4" then release it.
• if the blade guard freely drops down against
the table surface, then it is functioning cor-
rectly and is ready for operation.
• if the blade guard remains in the position
where you released it, or it does not drop
down against the surface of the table, then
the mounting screw is too tight. loosen it a
little and repeat this test until the guard func-
tions correctly.
• if the blade guard feels loose and easily
moves back and forth as you raise it, then the
mounting screw is too loose. tighten it a little
and repeat this test until the guard functions
correctly.
