NOTICE
To prevent damage to gearbox components,
NEVER move levers while lathe is running,
and NEVER force any lever when shifting. If
lever will not engage, rotate chuck by hand
while keeping light pressure on lever. As
chuck rotates it aligns gears and lever will
engage.
3.
Position lever pins in the gearbox holes indi-
cated on chart.
— Pull knurled knob out which releases lever
pin from hole.
— Lower lever below gearbox and slide it
directly under desired hole.
— While pulling knurled knob out, raise lever
so that pin is directly over hole, then
release knob to seat pin (see Figure 67 for
an example).
