Feed Selection Feed Lever
Never move the feed rate lever while machine
is running.
The Model G4015Z Lathe/Mill has 2 feed control
levers which must be engaged in order to use the
powerfeed or threading feature.The
Feed Rate
Lever , shown in Figure 18 , controls internal
gears that change the feed rate by a factor of 2.
Turning the lever to position “I” will cause the
Lead Screw to turn at twice the rate as when it is
in position “II”. When this lever is straight up, the
gearing is in neutral and no power feed is avail-
able.
Important:
Do not force any lever on the machine. If the
lever will not engage, rotate the chuck
by hand
while keeping light pressure on the selector. As
the chuck rotates it aligns the gear teeth inside
the selector box and the selector will engage.
Figure 18. Feed Lever indicated by arrow.
While the Lead Screw can be placed in neutral
with the feed selection lever, another lever allows
the power feeding feature of the lathe to be
turned on and off. When turned to the left, as in
Figure 18 , the Feed Lever connects power to the
Lead Screw , providing power to the apron. When
turned to the right, the apron can be fed manual-
ly and the hand crank no longer turns by itself.
The apron cannot be moved manually unless the
Feed Rate Lever is in neutral or the Feed Lever is
turned to the right. Please see the caution below.
The crank handle turns
whenever the power feed
feature is used. Do not
rest your hand on it or
allow clothing to come
near it before engaging
feed lever or while it is
turning.
