1.This machine is designed and intended for use by properly trained and experienced personnel only. If you are not familiar with the proper safe use of mill/drills, do not use this machine until proper training and knowledge has been obtained.

2.Keep guards in place. Safety guards must be kept in place and in working order.

3.Remove adjusting keys and wrenches.

Before turning on machine, check to see that any adjusting wrenches are removed from the tool.

4.Reduce the risk of unintentional starting.

Make sure switch is in the OFF position before plugging in the tool.

6.Use the right tool. Do not force a tool or attachment to do a job for which it was not designed.

7.Maintain tools with care. Keep tools sharp and clean for best and safest performance. Follow instructions for lubrication and changing accessories.

8.Always disconnect the tool from the power source before adjusting or servicing.

9.Check for damaged parts. Check for alignment of moving parts, breakage of parts, mounting, and any other condition that may affect the tools operation. A guard or any part that is damaged should be repaired or replaced.

10.Turn power off. Never leave a tool unattended. Do not leave a tool until it comes to a complete stop.

11.Keep work area clean. Cluttered areas and benches invite accidents.

12.Do not use in a dangerous environment.

Do not use power tools in damp or wet locations, or expose them to rain. Keep work area well lighted.

13.Keep children and visitors away. All visitors should be kept a safe distance from the work area.

15.Wear proper apparel. Loose clothing, gloves, neckties, rings, bracelets, or other jewelry may get caught in moving parts. Non-slip footwear is recommended. Wear protective hair covering to contain long hair. Do not wear any type of glove.

16.Always use safety glasses. Every day glasses only have impact resistant lenses; they are not safety glasses.

17.Do not overreach. Keep proper footing and balance at all times.

19.Do not perform any set-up work while machine is operating.

20.Read and understand all warnings posted on the machine.

21.This manual is intended to familiarize you with the technical aspects of this mill/drill.

It is not, nor was it intended to be, a training manual.

22.Failure to comply with all of these warnings may result in serious injury.

23.Some dust created by power sanding, sawing, grinding, drilling and other construction activities contains chemicals known to cause cancer, birth defects or other reproductive harm. Some examples of these chemicals are:

•Lead from lead based paint

•crystalline silica from bricks and cement and other masonry products, and

•arsenic and chromium from chemicallytreated lumber.

Your risk from those exposures varies, depending on how often you do this type of work. To reduce your exposure to these chemicals: work in a well ventilated area, and work with approved safety equipment, such as those dust masks that are specifically designed to filter out microscopic particles

Tools Needed for Assembly

8” Adjustable Wrench or 1/4” to 1-1/4” Combination Wrench Set

(JMD-18 shown with optional CS-18 stand)

(JMD-18/18PFN only)

7.0 Assembly

1.Screw rubber handles (A, Fig. 1) onto handle rod (B, Fig. 1). Screw handle rod into downfeed hub (C, Fig. 1) and tighten. Flat spot on rod accommodates a combination or adjustable wrench. Note: Handle shafts are already installed into hub on JMD-18PFN.

2.Repeat for other two rod 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.

7.Install spindle guard assembly (Figure 3a).

8.0 Installation

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.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.

3.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.

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. 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 mill/drill 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.

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 230V, or hard wire the power cord.

Make sure the mill/drill is properly grounded.
