9.0 Lubrication
Lubricate ball oilers (A, Fig. 4) by the X/Y-axis
hand wheels, the oiler at the raising/lowering
crank handle, and the oiler on front of the bed
once daily with Mobil DTE® Oil Heavy Medium.
Lubricate the ways (B, Fig. 4) once daily with
Mobil DTE® Oil Heavy Medium.
If the head does not rise or lower smoothly,
apply Mobilith AW2 to the rack, and Mobil DTE®
Oil Heavy Medium to the column.
If the feed handles do not turn smoothly, apply
Mobilith AW2 to the cross and longitudinal lead
screws (C, Fig. 4). Access the cross lead screw
by moving the table forward and removing the
way cover.
The spindle bearings are permanently sealed
and require no lubrication.
10.0 Electrical Connections
A qualified electrician must
make all electrical connections. Make sure
the Mill-Drill is properly grounded. Failure to
comply may cause serious injury.
Before making any electrical connections, make
sure the power source available is compatible
with the machine. Also, turn the machine OFF
using the buttons or switch at the front of the
machine before connecting to the power source.
The JMD Mill/Drills are rated at 115/230V and
come from the factory prewired at 115V. The
JMD-15 comes with a plug designed for use on
a circuit with an outlet that looks like the one in
Fig. 5, and has a grounding prong as illustrated
in Fig. 5. The JMD-18 and JMD-18PFN are not
provided with a plug.
To switch the Mill/Drill to 230V operation:
1. Disconnect machine from power source.
2. Remove junction box cover on the motor.
3. Change the wires according to the diagram
on the inside of the junction box cover, and
reinstall junction box cover.
4. Replace thermal relay with one rated for
230V operation (see parts list).
5. Change power plug to one rated for 230V
and the appropriate amperage for your
machine, or hard wire the power cord to the
service panel (make sure a disconnect is
available for the operator).
