LOCKING SWITCH IN “OFF” POSITION

IMPORTANT: When the machine is not in use, the switch should be locked in the “OFF” position to prevent unauthorized use, using a padlock with a 3/16" diameter shackle through the holes at (B) FIg. 13.

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).

ADJUSTING BLADE TENSION

DISCONNECT MACHINE FROM

POWER SOURCE.

1.Turn blade tension handwheel (A) Fig. 16, clockwise to increase or counterclockwise to decrease blade tension. Correct tension is obtained when the blade is just tight enough that no slippage occurs between the blade and the wheels.

2.When the machine is not in use, release the blade tension.
