1.0 IMPORTANT SAFETY

INSTRUCTIONS

WARNING – To reduce risk of injury:

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

2. Read and understand the 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 wood lathe 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 wood lathe, do not use it until the proper training and knowledge have been obtained.

5. Do not use this lathe for other than its intended use. If used for other purposes, JET disclaims any real or implied warranty and holds itself harmless from any injury that may result from that use.

6. Always wear ANSI Z87.1 approved safety glasses or face shield while using this drum sander. (Everyday eyeglasses only have impact resistant lenses; they are not safety glasses.)

7. Make certain the machine is properly grounded.

8. Before operating the machine, remove tie, rings, watches, other jewelry, and roll sleeves up past the elbows. Remove all loose clothing and confine long hair. Do not wear gloves.

9. Keep the floor around the machine clean and free of scrap material, oil and grease.

10. Keep machine guards in place at all times when the machine is in use. If removed for maintenance purposes, use extreme caution and replace the guards immediately.

11. Do not over reach. Maintain a balanced stance at all times, so that you do not fall or lean against rotating parts.

12. Make all machine adjustments or maintenance with the machine unplugged from the power source.

13. Use the right tool. Do not force a tool or attachment to do a job that it was not designed to do.

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

15. Give your work undivided attention. Looking around, carrying on a conversation and "horseplay" are careless acts that can result in serious injury.

16. Keep visitors a safe distance from the work area. Keep children away.

17. Make your workshop child proof with padlocks, master switches or by removing starter keys.

18. Maintain a balanced stance at all times so that you do not fall onto moving parts. Do not overreach or use excessive force to perform any machine operation.

19. Use recommended accessories; improper accessories may be hazardous.

20. Do not operate this lathe while under the influence of drugs, alcohol or any medication.

21. Keep tools sharp and clean for safe and best performance. Dull tools can grab in the workpiece and be jerked from the operator's hands, causing serious injury.

22. Check the condition of the stock to be turned. Make sure it is free of knots, warpage, checked ends, improperly made or cured glue joints and other conditions which can cause it to be thrown out of the lathe.

23. Securely fasten spur and live centers to the material being used.

24. Check centers and tapers in the headstock and tailstock to be sure they are free of dirt or rust, and oil lightly before inserting centers.

25. Test each set-up by revolving the workpiece by hand to ensure it clears the tool rest and bed. Check the setup at the lowest speed before increasing to operating speed.

26. Use the correct cutting tool for the operation to be performed and keep all tools sharp.

27. Use low speeds for roughing and for long or large diameter work. If vibration occurs, stop the machine and correct the cause.

28. When sanding, remove the tool rest from the machine, apply light pressure and use a slow speed to avoid heat buildup.

29. When turning large diameter pieces, such as bowls, always operate the lathe at low speeds. See speed recommendation chart in sect.

12.0.

30. Do not attempt to engage the spindle lock pin until the spindle has stopped. If leaving the machine area, turn lathe off and wait until the spindle stops rotating before departing.

31. Make no adjustments except speed changes with the spindle rotating, and always disconnect the machine from the power source when performing maintenance to avoid accidental starting or electrical shock.

32. Provide for adequate space surrounding work area and non-glare, overhead lighting.

33. When stopping the lathe, never grab the workpiece or faceplate to slow it down. Let the work coast to a stop.

34. Use only JET factory authorized replacement parts and accessories; otherwise, the warranty and guarantee are null and void.

35. 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 (sect. 6.3) shows 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.

), and insert it

6.0 Electrical connections

Electrical connections must

be made by a qualified electrician in compliance with all relevant codes. This machine must be properly grounded to help prevent electrical shock and possible fatal injury.

The JWL-1640EVS lathe requires 115-volt singlephase input. It is equipped with a power inverter, located between the power cord and the drive motor. The inverter takes the 115V 1-phase input from the power cord and converts it to the 230V 3phase output required by the drive motor.

The lathe comes with a plug designed for use on a circuit with a grounded outlet that looks similar to the one pictured in A, Figure 6-1.

Before connecting to power source, be sure switch is in off position.

It is recommended that the lathe be connected to a dedicated 15 amp circuit with a circuit breaker or fuse. If connected to a circuit protected by fuses, use time delay fuse marked “D”. Local codes take precedence over recommendations.

6.1 GROUNDING INSTRUCTIONS

This tool must be grounded. 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 inserted into an appropriate outlet that is properly installed and grounded in accordance with all local codes and ordinances.

Improper connection of the

equipment-grounding conductor can result in a risk of electric shock. Check with a qualified electrician or service person if you are in doubt as to whether the outlet is properly grounded. Do not modify the plug provided with the tool – if it will not fit the outlet, have a proper outlet installed by a qualified electrician.

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

Use only 3-wire extension cords that have 3-prong grounding plugs and 3-pole receptacles that accept the tool's plug.

Repair or replace damaged or worn cord immediately.

6.2 115V operation

As received from the factory, your JWL-1640EVS is ready to run at 115-volt operation. This tool is intended for use on a circuit that has an outlet that looks like the one illustrated in A, Figure 6-1. An adapter, shown in B, may be used to connect this plug to a 2-pole receptacle as shown in B if a properly grounded outlet is not available. The temporary adapter should be used only until a properly grounded outlet can be installed by a qualified electrician. The green-colored rigid ear, lug, and the like, extending from the adapter must be connected to a permanent ground such as a properly grounded outlet box. Note: In Canada, the

use of a temporary adaptor is not permitted by the Canadian Electrical Code, C22.1.

Figure 6-1: grounding

IMPORTANT: The JWL-1640EVS Lathe cannot be run on a GFCI circuit.

A lightning strike or power

surge may cause inverter failure. When lathe is not in use, disconnect power plug, or have a 3or 4-pole disconnect installed on the power side.

6.3 Extension cords

The use of extension cords is discouraged; try to position equipment within reach of the power source. If an extension cord becomes necessary, be sure it is 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 recommended size to use depending on cord length and nameplate ampere rating. If in doubt, use the next heavier gauge. The smaller the gauge number, the heavier the cord.

Figure 7-1: headstock movement

7.2 Tailstock movement

To slide tailstock, push locking handle (C, Figure 7-

3) down toward bed. Push handle up to lock tailstock in position.

To move quill, loosen handle (D) and rotate handwheel (E).

Make sure tailstock is locked

to bed (C) and quill is tightened (D) before turning a spindle on the lathe.

7.0 Adjustments

7.1 Headstock movement

Push handle (A, Figure 7-1) downward to unlock. Headstock will slide freely along length of bed. Push handle up to lock.

Always lock headstock in

position before operating lathe.

Figure 7-3: tailstock movement

7.3 Removing items from bed

To remove headstock, tailstock or toolrest base from bed, unscrew and remove either of the studs (see O, Figure 5-6). Unlock the item and slide it off bed. After remounting these items on the lathe, reinstall studs.

For most turning operations, except outboard turning, the headstock is positioned at the left end of bed, and the tailstock moved to accommodate the workpiece.

7.4 Cam tightness

The clamping mechanisms of headstock, tailstock and tool rest base are pre-set by the manufacturer, and should not require adjustment.

If one of them does not tighten properly against the bed when the locking handle is tightened, adjust it as follows. (Figure 7-4 uses tailstock as example.)

Figure 7-4: cam adjustment

1. Remove stud from end of lathe bed, and slide tailstock off.

2. Turn tailstock on its side, and tighten lock nut (F, Figure 7-4) to increase cam pressure, or loosen the nut to relieve cam pressure.

3. Mount tailstock on bed and lock it to verify adjustment. Repeat as needed.

4. Reinstall stud.

when the headstock is at the opposite end. See Figure 7-6.

Make sure the clamp bushings (K) are pulled apart sufficiently to accept tool rest post.

Figure 7-6: optional tool rest extension

7.7 Locking handles

Locking handles, such as H-Figure 7-5, are adjustable. Simply lift out on handle, rotate it on the pin, then release it, making sure it seats itself on the pin.

7.5 Tool rest

See Figure 7-5.

7.8 Spindle indexing

See Figure 7-7.

Indexing is used to create evenly spaced features in a workpiece, while keeping the lathe spindle locked; for example, when cutting flutes on a spindle blank with a hand-held router, while the spindle blank is secured between lathe centers.

The JWL-1640EVS lathe provides 36 indexing positions at 10-degree increments.
