Warnings

1. Read and understand the entire owner's manual before attempting assembly or operation.

2. Read and understand warnings posted on the machine and in this manual. Failure to comply with all of these warnings may cause serious injury.

3. Replace warning labels if they become obscured or removed.

4. This drill press is designed and intended for use by properly trained and experienced personnel only. If you are not familiar with the proper and safe operation of a drill press, do not use until proper training and knowledge have been obtained.

5. Do not use this drill press for other than its intended use. If used for other purposes, Walter Meier

(Manufacturing), Inc., disclaims any real or implied warranty and holds itself harmless from any injury that may result from that use.

6. Keep guards in place and in working order when the machine is in use. If removed for maintenance purposes, use extreme caution and replace the guards immediately.

7. Remove adjusting keys and wrenches. Form habit of checking to see that keys and adjusting wrenches are removed from tool before turning it on.

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

9. Do not use in dangerous environment. Don't use power tools in damp or wet locations, or expose them to rain. Keep work area well lighted.

10. Keep children away. All visitors should be kept safe distance from work area.

11. Make workshop kid proof with padlocks, master switches, or by removing starter keys.

12. Don't force tool. It will do the job better and safer at the rate for which it was designed.

13. Use the right tool. Don’t force a tool or attachment to do a job for which it was not designed. The right tool will do the job better and more safely at the rate for which it was designed.

14. Use proper extension cord. Make sure your extension cord is in good condition. When using an extension cord, be sure to use one heavy enough to carry the current your product will draw. An undersized cord will cause a drop in line voltage resulting in loss of power and overheating. Table 1 shows the correct size to use depending on cord length and nameplate ampere rating. If in doubt, use the next heavier gage. The smaller the gage number, the heavier the cord.

15. Wear proper apparel. Do not wear loose clothing, gloves, neckties, rings, bracelets, or other jewelry which may get caught in moving parts. Nonslip footwear is recommended. Wear protective hair covering to contain long hair.

16. Always use safety glasses. Also use face or dust mask if cutting operation is dusty. Everyday eyeglasses only have impact resistant lenses, they are NOT safety glasses.

17. Secure work. Make sure the work piece is securely attached or clamped to the table. Never use your hand to hold the work piece.

18. Don't overreach. Keep proper footing and balance at all times.

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

20. Disconnect tools before servicing; when changing accessories, such as blades, bits, cutters, and the like.

21. Reduce the risk of unintentional starting. Make sure switch is in off position before plugging in.

22. Use recommended accessories. Consult the owner's manual for recommended accessories. The use of improper accessories may cause risk of injury to persons.

23. Never stand on tool. Serious injury could occur if the tool is tipped or if the cutting tool is unintentionally contacted.

4

24. Check for damaged parts. Before further use of the tool, a guard or other part that is damaged should be carefully checked to determine that it will operate properly and perform its intended function - check for alignment of moving parts, binding of moving parts, breakage of parts, mounting, and any other conditions that may affect its operation.

25. A guard or other part that is damaged should be properly repaired or replaced.

26. Do not leave tool running unattended. Turn power off. Don't leave tool until it comes to a complete stop.

27. Some dust created by power sanding, sawing, grinding, drilling and other construction activities contain 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, cement and other masonry products.

• Arsenic and chromium from chemically treated lumber.

Your risk of exposure 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 face or dust masks that are specifically designed to filter out microscopic particles.

28. Make certain the switch is in the OFF position before connecting the machine to the power supply.

29. Make certain the machine is properly grounded.

30. Give your work undivided attention. Looking around, carrying on a conversation and “horse-play” are careless acts that can result in serious injury.

31. The operator should not wear gloves when operating the machine.

32. All doors should be closed, all panels replaced and other safety guards should be in place prior to the machine being started or operated.

33. Be sure the drill bit is not in contact with the work piece when the motor is started. The motor should be started and up to full speed before bringing the drill bit into contact with the work piece.

34. Keep your hands away from the drilling area.

35. The drill press must be stopped and the electrical supply must be cut off before any drill bit replacement or machine adjustment is done, or before any attempt is made to change the drive belts or before any periodic service or maintenance is performed on the drill press.

36. Remove loose items and unnecessary work pieces from the area before starting the machine.

37. The work piece must be securely clamped before the drill bit comes in contact with the work piece.

38. The drill press must be stopped and the electrical supply cut off or machine unplugged before reaching into the drilling area.

39. Wear eye protection.

40. Do not remove jammed pieces until motor has stopped.

41. Hold workpiece firmly against table.

Drilling Recommendations

Speeds for Drilling

The speed of a drill is usually measured in terms of the rate at which the outer periphery of the tool moves in relation to the work being drilled.

The common term for this is Surface Feet per

Minute (SFM). The relationship of SFM is expressed in the following formulas:

SFM

=

0 .

26

×

RPM

×

Drill Diameter ( in Inches )

RPM

=

3 .

8

×

Drill

SFM

Diameter ( in Inches )

In general, the higher the speed the shorter the drill life. Operating at the low end of the speed range for a particular material will result in longer life. The most efficient speed for operating a drill depends on many variables:

1. Composition and hardness of material.

2. Depth of the hole.

3. Efficiency of the cutting fluid.

4. Type and condition of the drilling machine.

5. Desired quality of the hole.

6. Difficulty of set-up.

Indication of Extreme Speeds and Feeds

A drill that splits up the web is evidence of too much feed or insufficient tip clearance at the center as a result of improper grinding. The rapid wearing away of the extreme outer corners of the cutting edges indicates that the speed is too high. A drill chipping or breaking out at the cutting edges indicates that either the feed is too heavy or the drill has been ground with too much tip clearance.

Speeds for High Speed Steel Drills

4. Remove belt. (With speed control setting at the highest speed, the belt should be loose enough to remove.)

5. Install the replacement belt. Install the head cover.

6. Connect electrical power to the drill press.

7. Operate the drill press to verify correct operation.

Adjustments

Table Adjustment

The table can be raised or lowered to accommodate the height of the component being drilled (refer to Figure 9). To raise or lower the table, loosen the lock handle. Then use the hand crank to move the table to the desired height. Then retighten the lock handle.

Figure 9 – Table Adjustment

Head Adjustment

Change the radial position of the drill head only if the drill press base is secured to the floor. Swinging the drill head without the base being secured to the floor will cause the drill press to become unstable and tip over resulting in injury and/or damage to the machine.

The radial position of the drill head can be changed to accommodate the drilling of a hole that may be offset from the center of the table.

Reposition the drill head by loosening the locking handles and swinging the drill head to the desired position. Then retighten the locking handles.

Wiring Diagrams

Refer to Figure 5 for wiring information. The drive motor is115/230 volt single phase or

Referring to Figure 12:

If 230V, single-phase operation is desired, the following instructions must be followed:

1. Disconnect the machine from the power source.

2. The JET drill press motor has four numbered leads that are factory connected for 115V operation, as shown in (A). For

230V operation reconnect the leads as shown in (B).

3. The 115V attachment plug (C), supplied with the drill press, must be replaced with a UL listed plug suitable for 230V operation (D).

Contact your local Authorized JET Service

Center or qualified electrician for proper procedures to install the plug. The drill press must comply with all local and national codes after the 230-volt plug is installed.

4. The drill press with a 230-volt plug should only be connected to an outlet having the same configuration as shown in (D). No adapter is available nor should be used with the 230-volt plug.

Permanently Connected Tools

Models J-A3816, J-A5816 and J-A5818 drill presses that are intended for permanent connection should be connected to a grounded metal permanent wiring system or to a system having an equipment-grounding conductor.

Grounding Instructions

This tool must be grounded while in use to protect the operator from electric shock.

In the event of a malfunction or breakdown, grounding provides a path of least resistance for electric current to reduce the risk of electric shock. This tool is equipped with an electric cord having an equipment-grounding conductor and a grounding plug. The plug must be plugged into a matching outlet that is properly installed and grounded in accordance with all local codes and ordinances.

Do not modify the plug provided. If it will not fit the outlet, have the proper outlet installed by a qualified electrician.

Improper connection of the equipmentgrounding conductor can result in a risk of electric shock. The conductor, with insulation having an outer surface that is green with or without yellow stripes, is the equipmentgrounding conductor. If repair or replacement of the electric cord or plug is necessary, do not connect the equipment-grounding conductor to a live terminal.

Check with a qualified electrician or service personnel if the grounding instructions are not completely understood, or if in doubt as to whether the tool is properly grounded. Use only three wire extension cords that have three-prong grounding plugs and three-pole receptacles that accept the tool’s plug.

Repair or replace a damaged or worn cord immediately.

Extension Cords

Make sure your extension cord is in good condition. When using an extension cord, be sure to use one heavy enough to carry the current your machine will draw. An undersized cord will cause a drop in the line voltage resulting in power loss and overheating. The table following shows the correct size to use depending on the cord length and name plate ampere rating. If in doubt, use the next heavier gauge. Remember, the smaller the gauge number, the heavier the cord.

12

The drill press with a 230-volt plug should only be connected to an outlet having the same configuration (D, Fig. 12). No adapter is available or should be used with the 230-volt plug.

Important: In all cases (115 or 230 volts), make certain the receptacle in question is properly grounded. If you are not sure, have a registered electrician check the receptacle.
