Assembly
1. Screw plastic knob (A, Fig. 1)onto handle shaft
(B, Fig. 1). Screw handle shaft intodownfeed
hub (C, Fig. 1) and tighten. Flatspot on shaft
accommodates a combination or adjustable
wrench. Note: Handle shafts are already
installed into hub on JMD-18PFN.
2. Repeat for other two shaft assemblies.
3. Slide crank (A, Fig. 2) onto shaft andtighten set
screw (B, Fig. 2). Be sure set screw seats on flat
part of shaft.
4. Insert handle (C, Fig. 2) into crank and tighten.
5. Slide handwheel (A, Fig. 3) onto table
handwheel shaft and tighten set screw. Insert
handle (B, Fig. 3) intohandwheel and tighten.
6. Repeat for two remainingtable handwheels.
Installation
1. The location for the mill/drill should be well lit,
dry, and have room enough to allow the headto
rotate 3600.
Fig. 1
Fig. 2
~.
2. Place nylon slings with a load rating exceeding
the weight of the mill/drill around the head so
that the sling will not damage any parts when
tensioned. See Fig.4.
3. Carefully lift the mill/drillto a sturdy stand or work
bench. For best performance, through bolt the
mill/drill to a benchor stand.
4. Before bolting the mill/drillto a bench or stand,
the unit must be level in both directions. Place a
level on the table in both directions.
5. If the table is not level, shim under the low corner
(s) untilleve!. Tighten the fastening bolts.
Check for level again. Adjust as necessary until

the mill/drill is level after the fastening hardware
has been tightened.
Lubrication
Lubricate all ball oilers on the machine once daily
with 20W machine oil.
The spindle bearings are permanentlysealed and
require no lubrication.
Electrical Connections
CURRENT CARRYING PRONGS
w
e
Before making any electrical connections, make sure
the power source available is compatible with the
machine. Also, press the Off switchon the front of
the machine before connecting to the power source.
The JMO-15 is rated at 115/230Vand comes from
the factory prewired at 115V. This mill/drillcomes
with a plug designed for use on a circuitwith an
outlet that looks like (A) in Fig. 5. The JMO-15has a
grounding prong as illustratedin (B). A temporary
adapter (C) may be usedto connect the plugto a
two pole receptacle (0) if a properly grounded outlet
is not available. The temporary adapter should only
be used until a qualified electriciancan install a
properly grounded outlet. The green colored plug
must be securely fastened to the cover platescrew.
To switch the JMO-15 to 230V operation:
1. Disconnectthe machine from the power
source.
2. Removethe junction box cover on the motor.
3. Change the wires according to the diagram on
the inside of the junction box cover.
