If the threading or general carriage feed is
required, the carriage lock (see
Figure 91
) must
be disengaged. If the cross feed will be used for
facing, the carriage lock should be engaged and
the cross feed gib lock screw (see
Figure 91
)
should be loose. If it is tight, loosen the cross feed
gib lock using a 3mm hex wrench.
To engage the power feed:
1.
Make sure the spindle is
OFF
and has come
to a complete stop.
2.
Shift the headstock feed direction lever to
engage the leadscrew or feed rod. Sometimes
you need to slightly rotate the handwheel of
the component you are trying to engage, so
that the gears can mesh.
NEVER shift the headstock feed direction lever
on the headstock while the spindle is turning,
or damage will occur to the headstock gearing.
3.
Push down on the feed ON/OFF lever (see
Figure 91
) on the front of the apron to
engage power feed for either the carriage or
the cross slide.
4.
Push the feed selection knob in to select
carriage feed, or pull the feed selection knob
out to select cross feed.
5.
Adjust the feed clutch knob, shown in
Figure 92
, to set at which point the feed
clutch will slip to avoid feed system overload.
— Tighten the feed clutch knob completely
to seat the clutch. Next, count how many
turns it takes to back it off completely.
Then tighten the knob
1
⁄
3
of the distance
that was backed-off. If the clutch slips
too easily at this conservative setting, the
knob can be tightened further. But keep
in mind that when the knob is completely
tight, the feed clutch is overridden
and will not slip in the event of a feed
system overload, resulting in feed system
damage.
To use the apron feed direction knob during
lathe operations:
1.
Pull up on the feed ON/OFF lever to
disengage the apron feed system.
2.
Push in or pull out the apron feed direction
knob to change the direction of the current
feed selected.
3.
Push down on the feed ON/OFF lever to
resume the feed operation in the opposite
direction.
