Read and follow these simple rules for best results and full benefits from your machine. Used properly, JET machinery is among the best in design and safety. However, any machine used improperly can be rendered inefficient and unsafe. It is mandatory that those who use our products be properly trained in how to use them correctly. They should read and understand the Operating Instructions and Parts Manual as well as all labels affixed to the machine. Failure to follow all of these warnings can cause serious injuries.

3.1 Machinery General Safety Warnings

1. Always wear protective eye wear when operating machinery. Eye wear shall be impact resistant, protective safety glasses with side shields which comply with ANSI Z87.1 specifications. Use of eye wear which does not comply with ANSI Z87.1 specifications could result in severe injury from breakage of eye protection.

2. Wear proper apparel. No loose clothing or jewelry which can get caught in moving parts. Contain long hair. Rubber soled footwear is recommended for best footing.

3. Do not overreach. Failure to maintain proper working position can cause you to fall into the machine or cause your clothing to get caught — pulling you into the machine.

4. Keep guards in place and in proper working order. Do not operate the machine with guards removed.

5. Avoid dangerous working environments. Do not use stationary machine tools in wet or damp locations, or in an explosive environment. Keep work areas clean and well lit. Special electrics should be used when working on flammable materials.

6. Avoid accidental starts by being sure the start switch is “OFF” before plugging in the machine.

7. Machinery must be anchored to the floor.

8. Never leave the machine running while unattended. Machine shall be shut off whenever it is not in operation.

9. Disconnect electrical power before servicing. Whenever changing accessories or general maintenance is done on the machine, electrical power to the machine must be disconnected before work is done.

10. Maintain all machine tools with care. Follow all maintenance instructions for lubricating and the changing of accessories. No attempt shall be made to modify or have makeshift repairs done to the machine. This not only voids the warranty but also renders the machine unsafe.

11. Secure work. Use clamps or a vise to hold work, when practical. It is safer than using your hands and it frees both hands to operate the machine.

12. Never brush away chips while the machine is in operation.

13. Keep work area clean. Cluttered areas invite accidents.

14. Remove adjusting keys and wrenches before turning machine on.

15. Use the right tool. Don’t force a tool or attachment to do a job for which it was not designed.

16. Use only recommended accessories and follow manufacturer’s instructions pertaining to them.

17. Keep hands in sight and clear of all moving parts and cutting surfaces.

18. All visitors should be kept a safe distance from the work area. Make workshop completely

safe by using padlocks, master switches, or by removing starter keys.

19. Know the tool you are using; its application, limitations, and potential hazards.

3.2 General Electrical Cautions

This machine must be grounded in accordance with the National Electrical Code and local codes and ordinances. This work should be done by a qualified electrician. The machine must be grounded to protect the user from electrical shock.

Caution: For circuits which are far away from the electrical service box, the wire size must be increased in

order to deliver ample voltage to the motor. To minimize power losses and to prevent motor overheating and burnout, the use of wire sizes for branch circuits or electrical extension cords according to the following table is

recommended:

Conductor Length

0 – 50 Ft. No. 14 No. 14

3.3 Safety Instructions for Drill Presses

1. All work shall be secured using either clamps or a vise to the drill press table. It is unsafe to use your hands to hold any workpiece being drilled.

2. Drill press head and table shall be securely locked to the column before operating the drill press. This must always be checked prior to starting the machine.

3. Always use the correct tooling. Tooling shall always be maintained and properly sharpened. All tooling must be run at the proper speeds and feeds as they apply to the job. Use only recommended accessories and follow those manufacturer’s instructions pertaining to them. Tooling shall not be forced into any workpiece but fed according to the proper specifications. Failure to follow these instructions will not only ruin the tooling as well as the machine, but can cause serious injury.

4. Never brush away shavings or chips while the machine is in operation. All clean up should be done after the machine is stopped.

5. Keep hands in sight. Do not put hands or fingers around, on, or below any rotating cutting tools. Leather safety gloves should be used when handling any sharp objects or cutting tools. See Figure 1A.

6. Always use protective eyewear when operating, servicing or adjusting machinery. Eyewear shall be impact resistant, protective safety glasses with side shields complying with ANSI Z87.1 specifications. Use of eye wear which does not comply with ANSI Z87.1 specifications could result in severe injury from breakage of eye protection. See Figure 1B.

7. When drilling in material which causes dust, a dust mask shall be worn. See Figure 1C.

8. Avoid contact with coolant, especially guarding the eyes.

9. Non-slip footwear and safety shoes are recommended. See Figure 1D.

10. Wear ear protectors (plugs or muffs) during extended periods of operation. See Figure 1E.

4.0 Specifications

The JET Model J-1600R is a powerful and versatile radial arm drill press. The drill head is mounted on an arm and can slide along the arm to position the spindle over the work piece. The arm itself can be rotated on its support column to allow centering the spindle over the work piece.

Drilling can be performed manually or with power feed assistance. In addition, parameters of RPM, power feed rate and drilling depth can be pre-set by the operator, using controls conveniently positioned on the drill head. The drill has an automatic tool ejector, and hydraulic head and column clamping system.

The power train gears and spline shaft are made of high quality heat-treated and ground nickel chrome steel, offering greater strength and smoothness to high-torque loads. The spindle is of case hardened steel and supported by dual row taper roller and thrust ball bearings at the nose, with thrust and radial axis bearings at the top. The frame is made of Meehanite® and high-tensile strength cast iron.

A precision machined box table allows convenient positioning and clamping of smaller work pieces. The box table can be removed from the base to allow larger workpieces to be clamped on the base itself. Both table and base have multiple T-slots for clamping set-ups.

performed only by a licensed electrician who is familiar with national and local electrical codes. This machine must be properly grounded to help prevent electrical shock and possible fatal injury.

Model J-1600R radial drills are tested before shipping for all functions and circuits under electrical power specified for the machine and motors. The only hook-up requirement should be for correct connection to an appropriate cutout on an appropriate service branch.

Where the following instructions do not agree with local electrical codes and procedures, the applicable codes and procedures should be followed, exclusively.

Wiring diagram

A wiring diagram for the drill press is found inside the door of the electrical cabinet. A similar diagram is shown in back of this manual. This diagram is for reference by your licensed installing or servicing electrician.

All three motors on the J-1600R are 3-phase motors of the same voltage value. All control circuits are 110 volt circuits. The motor’s circuit is

NOT fused. Thus, fuses for each leg of the 3phase service branch must be supplied by the installing electrician. If a service disconnect with

a fuse for each leg of the 3-phase branch is not supplied, then none of the motors are protected from electrical faults.

In addition to using a licensed electrician for connection to the drill press service branch, the servicing of components and circuits inside the control box should be serviced only by a qualified electrician. This includes fuse replacement, if required. If any of these fuses, upon replacement, should continue to fail at short service intervals, the electrician should be asked to check all machine components for excessive loads, short circuits or other failures.

Electrical branch service

The machine is wired for either a 230V or 460V, 3phase service branch. The cable supplying the drill press will be tagged with the voltage at which the machine was tested and corresponding to the customer's order.

If the tag has been lost, it will be necessary for you to open the electrical cabinet on the rear of the drill press and examine the connections on the transformer found inside the box. The transformer can be connected to either a 230 or 460 volt source and its taps are labeled for voltage. By locating the source tap on the transformer you will be able to determine the branch voltage required.

A service disconnect is recommended. The use of fuses or circuit breakers for each of the voltage supply wires is required. Use fuses or circuit breakers which are appropriate to the voltage for the motor system delivered.

A positive cut-out/lock-out lever or rocker switch should be located on the outside of the service disconnect to allow the machine operator to disconnect from the branch circuit when working with tooling on the machine.

It is recommended that the 230 volt Drill Press be

connected to a dedicated 25 amp circuit with a 25 amp circuit breaker or time delay fuse. Connect the

460 volt drill press to a dedicated, 15 amp circuit

with 15 amp circuit breaker or time delay fuse.

Local codes take precedence over recommendations.

Connecting br anc h to drill p ress

1. Disconnect service branch to machine by moving lever or rocker switch on cutout box to OFF.

2. Connect the green wire (or green with white trace) to the branch ground.

3. Connect the remaining three wires in the cable (labeled R, S and T) to the three power lines in the branch.

4. Turn power to the machine ON at the cutout box.

5. Turn coolant switch (See Figure 10) to ON position.

Make sure there is coola nt

in flood coolant system before operating pump. Failure to comply may cause damage to pump.

6. Observe rotation through glass atop pump. The shaft should be rotating in direction of arrow cast into pump assembly. If shaft is rotating wrong direction, the power leads need to be switched. Correct as follows:

7. Disconnect power to machine by turning it off at cutout box.

8. Reverse any two of the power lead

connections, R, S or T.

9. Repeat steps 4, 5, and 6, above, and you should observe pump shaft turning in proper direction. Electrical service to machine is now complete.

8. Re-establish power to machine, and the drill is ready to use.

8.1 Clamping workpieces

To load/unload heavier workpieces, unlock arm and rotate it out of the way. Lift the workpiece with slings or other properly rated lifting equipment.

Both the box table and base surface are slotted to accept a suitably sized T-slot clamp. Before beginning any work on the drill press, anchor the work piece, and box table if used, to be certain that workpiece and/or box table will not move when tool enters workpiece.

If box table will not be used, simply remove the nuts at the base, and move table off using proper lifting equipment.

Failure to properly anchor

workpiece and box table could result in damage to machine, damage to workpiece, a nd severe injury to machine operator. Never work on drill press without clamping the materials using a T-slot system set-up.

8.2 Tool insertion

The Model J-1600R uses a No. 5 Morse taper in the spindle to secure tooling. Any drill, milling cutter, or tool holder with an MT-5 can be inserted into the quill.

The first step in removing or

inserting any tooling is to be absolutely certain

the machine cannot be accidentally started during the insertion or removal operation. The

only way to be certain of this fact is to disconnect power to machine. The service box should have a cut-out switch or lever on the outside of the box. Position switch or lever in the OFF position before

inserting or removing tooling.

To insert tooling:

1. Verify that machine is disconnected from power.

2. Be certain the spindle is clean, free from oil, and ready to accept the shank of any tooling.

3. Check the shank of tooling to be certain the tooling is free from dirt, nicks or burrs. If nicks or burrs are discovered, file or stone the shank until it is smooth.

4. Pull the tooling ejection handle out to be

certain the tooling can be inserted. See Figure

10.

5. Be certain quill is in full UP position.

6. Slide shank of tooling into spindle until it seats.

7. Use a soft-faced mallet (such as lead, plastic, brass, etc.) to give the tooling a sharp tap on its tip. This will secure the tooling in the taper.

To remove tooling:

9. Verify that machine is disconnected from power.

10. Place a wood block under the tooling in spindle, to prevent it being damaged should it fall out during the removal process.

11. Use the feed levers to lower quill enough to allow tooling ejection handle to be pushed fully

inward.

12. While using leather gloves to hold the tooling and prevent it from falling loosely out of the spindle taper, use the feed levers to give the quill a sharp upward stroke against the top of its travel and the tooling will be released from the taper in the spindle.

13. Remove tooling and pull tooling ejection

handle out to allow new tooling to be inserted.

8.3 Tool positioning over workpi ece

After workpiece has been clamped to base or table, position the tooling over workpiece, using any or all of the following methods:

1. Adjusting height of arm on support column.

2. Moving drill head along arm.

3. Rotating column upon which arm and head are attached.

8.4 Unlocking arm and column

mechanisms

A motorized locking system is used to lock the head to the arm, the arm to the column, and the column to the base.

The buttons which control the locks are located in

center of drill head handw heel (see Figure 10).

Press and hold UNLOCK (green) button until arrow (Figure 11) points to “B”. Release button. Clamping device is now disengaged. When locking, press and hold LOCK (red) button until arrow points to “A”. Clamping device is now re-engaged.

NOTE: When you push UNLOCK, all of the locks are disengaged. When you push LOCK, all of the

locks are engaged.

Always be certain the locks

are engaged before using drill press. Pull on arm handle and try to rotate handwheel at front of head, before star ti ng spindle. Fai l ure to have all locks secure may result in damage to tooling, damage to workpiece, and possible injury to operator.
