SPINDLE OPERATION
Refer to Figures 6 and 7, pages 8 and 10.
Palmgren mill drill is equipped with
spindle fine feed handwheel and spin-
dle depth lockdown handle.
Engage fine feed handwheel (Fig. 6,
Ref. No. 36) by rotating pinion knob
clockwise (Fig. 6, Ref. No. 39) until tight.
Disengage fine feed by loosening pin-
ion knob.
Spindle depth can be locked into position
by tightening quill lock handle (Fig. 7,
Ref. No. 56). Bring spindle down to
desired position and tighten quill lock
handle to hold spindle position.
DEPTH STOP
Refer to Figures 6 and 7, pages 8 and 10.
Repeated operations where depth of cut
is consistent are made easier by using
depth scale (Fig. 6, Ref. No. 44) and
depth setting knob (Fig. 7, Ref. No. 61).
Depth of cut is shown on depth scale
and indicated by depth indicator
(Fig. 6, Ref. No. 45).
Depth of cut is set by rotating depth
setting knob until desired depth is
obtained.
HANDWHEEL SCALES
Refer to Figure 8, page 12.
The cross feed handwheel and right-
hand longitudinal handwheel are
equipped with graduated collars.
One full rotation of handwheel moves
table .100”. Handwheel scales are grad-
uated in .001”.
Scales are used when precise movement
of table is required.
Scales can be zeroed by loosening dial
screw (Ref. No. 5) and rotating lead
screw dial (Ref. No. 4) until zero marks
are aligned.
Tighten dial screw.
TABLE STOP BLOCKS
Refer to Figure 8, page 12.
Longitudinal travel can be limited to
make repeated operations easier by
using the table stop blocks (Ref. No. 27).
Table stop blocks are positioned to con-
tact table stop bracket (Ref. No. 21) lim-
iting table travel.
Adjust stop blocks by loosening socket
head bolts (Ref. No. 26) and moving
stop blocks to desired position. Secure
socket head bolts.
TABLE LOCKS
Refer to Figure 8, page 12.
Mill drill table can be locked into position
using table lock handles (Ref. Nos. 32 and
41).
Longitudinal position is secured by tight-
ening lock handles on front of saddle.
Cross feed position is secured by tighten-
ing lock handles on right side of saddle.
REMOVE ARBOR

turned off and is dis-
connected from power source before
removing arbor.
1. Loosen draw bar with one or two
turns.
2. Tap draw bar top with mallet to free
