(c) Operations:

1 Reversing Switch:
Motor turning is controlled by the reversing switch
(Vide the Figure in the right). When the high-low speed
change lever (Vide P21, 22) is placed at the high gear
position and the switch is on FOR, the motor turns
clockwise. When the switch is on REV, the motor turns
counterclockwise. When the switch is on OFF, then the
power source is cut off.
Note: When the high speed change lever is placed at the
low gear position, then, it is just on the opposite.
2 Chucking of Tool Shank and Dismantling:
First the spindle must be raised up to its maximum
height. The thread of draw bar is right turn. When the
screw is turned clockwise, it is for locking of tool shank,
and vice-versa. To take out the tool shank, the drawbar
must be turned from three to five rounds. Then, use a
soft mallet to hit lightly on the drawbar until the tool
shank comes off totally.
Note: According to Spindle Braking, brake the spindle to
a full stop and the tool shank may easily come off or
chuck on.
