Gearbox Levers

NOTICE
NEVER attempt to shift a lever while the lathe is run-
ning! And when shifting a lever, NEVER force it. If the
lever will not engage, rotate the chuck by hand while
keeping light pressure on the lever. As the chuck
rotates it aligns the gears and the lever will engage.
The two levers (Figure 40) at the bottom of the
headstock change the feed rate or the number of threads
cut per-inch. The left-hand lever engages in alpha
positions A, B, C, D, and E; and the right-hand lever
engages in numeric positions 1, 2, 3, 4, 5, 6, 7, and 8.
Use the feed rate chart shown in Figure 41 to position
the quick change gearbox levers.

Feed Rate Chart

The far left column in the feed rate chart (Figure 41)
shows which change gears must be installed so the chart
will be applicable.
For example: Using the metric chart to make a 0.158mm
per revolution longitudinal cut, refer to the row that has
this symbol: .
Then put the left-hand lever in the C position, and the
right-hand lever in the 4 position.
To perform a facing cut, use the chart the same way but
refer to the row that has this symbol:
Note: When either of the two selector levers are left in
the down position, the drive train is disengaged and is in
neutral.
