The relevant terms
NO.
Term
A
Depth controlling and fixing lever.
B
Main dial
C
Clutch adjusting block
D
Depth-setting ring
E
Feed trip lever
F
Depth reference point.
Preset the depth of the power-feed:
a. Rotate the feed trip lever counter clockwise as shown in picture E till The drill bit
contact the work piece. (At this moment, B and C shown in the pictures move
simultaneously. That’s the depth is zero when the bit is contacting the work piece and
the dial is also at the zero position. )
b. Release the fixing lever of the main dial. That’s to release A shown in the picture.
c. Rotate the depth setting ring as shown in picture D, referring to the depth point on the
ring. To set the drilling depth is to adjust and align the gauge on the ring as shown in
the picture B.
d. Clamp the fixing lever of the main dial. That’s to clamp A shown in the picture.
e. Release the feed trip lever as shown in the picture E.
f. Rotate the feed trip lever a little bit counter clockwise, as shown in the picture E.
g. Turn the spindle switch to “SPDL. FOR”.
h. Pull the feed trip lever backwards as shown in the picture E, The spindle will feed at the
chosen rate and stop

in the picture.
d. Clamp A, as shown in the picture.
e. Release E, as shown in the picture.
f. Rotate E in the picture a little bit counter clockwise.
g. Turn the spindle switch to SPDL. FOR
h. Pull the feed trip lever as shown in the picture E backwards.
Precaution
a. Auto feed will move only after the feed rate is set up.
b. Auto feed is used only in drilling, not in threading.
