Maintenance
Do not attempt
under any circum-
stances, to service, repair, dismatle, or
disassemble any mechanical or electrical
components without physically discon-
necting all powr sources.
Refer to Figures 5, 6, 7 and 8.
Keep all moving parts and surfaces
clean of dirt, metal chips, etc. Keep a
light coating of oil on all exposed sur-
faces, including table top and slots, all
dovetail way surfaces, lead screws, rack
and column.
Replace worn V-belts.
Check electrical connections and replace
any worn or frayed wires or line cords.
Replace worn way cover.
Replace work lamp bulb with maximum
40 watt bulb only.
GIB ADJUSTMENT
Refer to Figures 5 and 8, pages 6 and
12.
Palmgren mill drill is equipped with
adjustable gibs (See Figure 5) on longi-
tudinal and cross feed that eliminate
excess play in table as dovetail ways
wear over time.
Rotating gib adjustment bolts (Ref. No.
43) clockwise tightens dovetail ways.
Adjust gib bolts until a slight drag is felt
when moving the table with hand-
wheels. Loosen bolts if table is too tight.
REPLACE RETURN SPRING
Refer to Figure 6 and 7, pages 8 and 10.
Return spring may wear after extended
use and will need replacement. If spindle
does not return to full up position when
released, then replace return spring.
Spring is under ten-
sion and may tend
to twist forcefully when relaxed.
To replace return spring, push spindle
to fully up position and lock it in place
by tightening quill lock handle
(Fig. 7, Ref. No. 56).
Loosen spring cover bolt (Fig. 6, Ref. No.
11) slowly and carefully rotate spring
and cover clockwise to relax spring ten-
sion.
Remove spring cover bolt and washers
(Fig. 6, Ref. No. 11, 12 and 13). When
tension is released, rotate spring and
cover clockwise to release spring from
mounting screw.
Remove spring and cover. Place new
spring over pinion shaft and slide slot at
end of spring over mounting screw
(Fig. 6, Ref. No. 24). Press spring and
cover against head casting.
Replace washer and spring cover knob.
Rotate cover counterclockwise to tension
spring. Rotate cover approximately
three full turns and tighten cover knob.
Release quill lock handle.
Test spring tension by pulling down on
crank handle (Fig. 6, Ref. No. 38). Adjust
spring tension as needed.
Overtightening spring causes quill
to return with excessive force dam-
aging quill and rubber bumper
(Figure 7, Ref. Nos. 4 and 9).
Lubrication
Refer to Figures 6, 7 and 8, pages 8, 10
and 12.
Use medium weight, non-detergent oil.
DAILY:
1. Apply five to six drops of oil on
splines at the top of spindle (Fig. 7,
Ref. No. 2).
2. Be sure cross feed lead screw (Fig. 8,
Ref. No. 12) is clean of dirt and metal
chips. Oil if necessary.
WEEKLY:
1. Oil cross feed lead screw (Fig. 8, Ref.
No. 12).
2. Oil dovetail ways (Fig. 8, Ref. No. 11).
MONTHLY:
1. Oil handwheel bearings through oil
fittings (Fig. 8, Ref. No. 11).
2. Oil gear rack on back of quill where
pinion shaft (Fig. 6, Ref. No. 25)
engages quill (Fig. 7, Ref. No. 4).
3. Oil depth stop lead screw (Fig. 7, Ref.
No. 61).
4. Apply bearing grease to rack (Fig. 8,
Ref. No. 14) and pinion shaft (Fig. 6,
Ref. No. 25). Remove pinion knob
and handle base (Fig. 6, Ref. Nos. 39
and 40) to expose pinion shaft.
5. Grease longitudinal lead screw (Fig. 8,
Ref. No. 25).
