Assembly

1.Screw rubber handles (A, Fig. 1) onto handle shaft (B, Fig. 1). Screw handle shaft into downfeed hub (C, Fig. 1) and tighten. Flat spot 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 (D, Fig. 2) onto shaft and tighten set screw (E, Fig. 2). Be sure set screw seats on flat part of shaft.

4.Thread handle (F, Fig. 2) into crank and tighten.

5.Slide handwheel (G, Fig. 3) onto table handwheel shaft and tighten set screw. Insert handle (H, Fig. 3) into handwheel and tighten.

6.Repeat for two remaining table hand wheels.

Installation

WARNING

Machine is heavy! Use an appropriate lifting device and use extreme caution when moving the machine to its final location. Failure to comply may cause serious injury!

1.The location for the mill/drill should be well lit, dry, and have room enough to allow the head to rotate 360°.

2.Open the belt cover and thread the lifting hook into the head. There is a threaded hole found between the column and the spindle pulley.

3.Carefully lift the mill/drill with properly rated equipment to a sturdy stand or work bench. For best performance, through bolt the mill/drill to a bench or stand.

4.Remove the lifting hook.

5.Before bolting the mill/drill to a bench or stand, the unit must be level in both directions. Place a level on the table in both directions.

6.If the table is not level, shim under the low corner(s) until level. Tighten the fastening

bolts. Check for level again. Adjust as necessary until the mill/drill is level after the fastening hardware has been tightened.

7

Lubrication

Lubricate ball oilers (A, Fig. 4) found by the X/Y- axis hand wheels, the oiler found by the raising/lowering crank handle, and the oiler on the 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 raise, 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.

Electrical Connections

WARNING

A qualified electrician must make all electrical connections!

Failure to comply may cause serious injury!

Before making any electrical connections, make sure the power source available is compatible with the machine. Also, press the “Off” button on the front of the machine before connecting to the power source.

The JMD-15 is rated at 115/230V and comes from the factory prewired at 115V. This mill/drill comes with a plug designed for use on a circuit with an outlet that looks like (A, Fig. 5). The JMD-15 has a grounding prong as illustrated in (A, Fig. 5).

To switch the JMD-15 to 230V operation:

1.Disconnect the machine from the power source.

2.Remove the junction box cover on the motor.

3.Change the wires according to the diagram on the inside of the junction box cover, and replace the junction box cover.

4.Change the plug to one that is rated 230V or hard wire the power cord.

The JMD-18/18PFN is rated at 230V only. Again, be sure the power source is compatible with the mill/drill before connecting to the power source. Make sure the mill/drill is properly grounded.

Controls

Longitudinal Hand Wheels: (X-axis) (A, Fig. 6)

Located on either side of the table. Moves table side to side.

Cross Feed Hand Wheel: (Y-axis) (B, Fig. 6)

Located on the front of the base. Moves table toward, or away from the column.

Adjustable Table Stops: (C, Fig. 6)

Located on table front. Adjust to stop table at any setting along the longitudinal axis.

Table Locks: (D & E, Fig. 6)

Longitudinal table locks are located on front of the table. Cross-feed table locks are located on the right side under the table. Turn clockwise to lock.

Depth Stop:

JMD-15: (K, Fig. 8) located on the left side. Set nuts for desired depth stop.

JMD-18: (F, Fig. 7) located in the front. Push in the button on the front of the quick adjust stop and move to desired position.

JMD-18PFN: Set the depth stop on the power down feed assembly to desired depth for repetitive drilling to the same depth, see “Power Feed Operation” on page 12.

Downfeed Handles: (G, Fig. 7)

Located on the right side of the head casting. Counter-clockwise movement advances the quill toward the table. Return spring retracts the handles. Note: the knob (I, Fig. 7) must be loose for the downfeed handles to work.

Fine Feed Hand Wheel: (H, Fig. 7)

Located on the front of the head casting. To activate, tighten the knob (I Fig. 7) and turn the power feed speed range dial (J, Fig. 7) to zero.
