10. Move the spindle ON/OFF lever to the OFF
(middle) position, as shown in Figure 33.
8. Set the spindle speed to 40 RPM. You may
have to manually rock the chuck back-and-
forth to make the gears mesh.
a. Turn the two-speed motor switch to the
LOW position.
b. Move the spindle range lever so that
the indicator points to the upper line on
the right—this is the low range for this
motor speed (see Figure 31).
c. Rotate the spindle speed lever so that
the indicator points to the "A".
9. To allow the carriage to move freely when
the handwheel is rotated, disengage the
half nut lever, put the feed control lever
in disengaged position, and make sure the
carriage lock is loose (see Figure 32).
DO NOT use the jog button to help mesh the
gears when changing spindle speeds or range.
This could damage the gears and connected
components.
