Model G0746/G0749 (Mfg. Since 3/13)
the handwheels shown in
figure 69 allow the
operator to manually move the cutting tool.
carriage Handwheel
the carriage handwheel moves the carriage left
or right along the bed. it has a graduated dial with
0.005" increments. one full revolution moves the
carriage 0.55".
cross Slide Handwheel
the cross slide handwheel moves the tool toward
and away from the work. adjust the position of
the graduated scale by loosening the thumb
knob, holding the handwheel with one hand and
turning the dial with the other, then tightening the
thumb knob. the cross slide handwheel has a
direct-read graduated dial, which shows the total
amount of material removed from the diameter
of the workpiece. the dial has 0.004" (0.01mm)
increments, and one full revolution moves the
slide 0.200". rotate the dial collar 180° to read in
metric units.
compound Rest Handwheel
the compound rest handwheel moves the cutting
tool linearly along the set angle of the compound
rest. adjust the position of the graduated scale
in a similar manner with the handwheel and dial.
the compound rest angle is set by hand-rotating
it and securing in place with four hex nuts. the
compound rest has an indirect-read graduated
dial with 0.002" (0.05mm) increments. one full
revolution of the handwheel moves the slide
0.200".

Use the micrometer stop as a guide to help judge
when to stop carriage movement.
The micrometer stop on this lathe will
NOT automatically stop the carriage during
threading operations when the carriage
is engaged with the leadscrew! failure to
heed this notice could result in the carriage
crashing and causing severe machine or
property damage.
