AUTOMATIC SHUT-OFF
When the band saw is in the horizontal position, the saw
should shut itself off automatically. After a completed
cut has been made, and the saw is in the down or
horizontal position, the shut-off bracket (B) Fig. 14 will
contact the toggle switch (A) and push it to the down
position, turning off the power. IMPORTANT: THE
SHUT-OFF BRACKET (B) SHOULD NOT REST ON OR
BE SUPPORTED BY THE TOGGLE SWITCH (A).
The downward travel of the saw should be adjusted to
just trip the toggle switch at its lowest position. To adjust
the downward travel of the saw arm, loosen lock nut (C)
Fig. 15, and turn the stop screw (D) in or out until the
correct adjustment is made; then tighten lock nut (C).
