14. Make certain the switch is in the OFF position before connecting the machine to the power supply. 1.0 IMPORTANT SAFETY INSTRUCTIONS 15. Give your work undivided attention. Looking around, carrying on a conversation and "horseplay" are careless acts that can result in serious injury. WARNING – To reduce risk of injury: 16. Keep visitors a safe distance from the work area. Keep children away. 1. Read and understand the entire owner’s manual before attempting assembly or operation. 2.
0. When sanding, remove the tool rest from the machine, apply light pressure and use a slow speed to avoid heat buildup. 35. When stopping the lathe, never grab the workpiece or faceplate to slow it down. Let the work coast to a stop. 31. When turning large diameter pieces, such as bowls, always operate the lathe at low speeds. See speed recommendation chart in sect. 12.0. 36. Use only JET factory authorized replacement parts and accessories; otherwise, the warranty and guarantee are null and void. 37.

5.0 Setup and assembly The Lathe must be disconnected from power during assembly. 5.
5.4.1 Hoist lifting method 1. The guard (part no. 719002) is optional and purchased separately. See our website for information. Position straps around lathe bed. IMPORTANT: Do not place straps around spindle, near levers, knobs or other parts that can be damaged when lifting. 2. Position lathe onto legs and secure with screws and washers (HP001/2/3, Figure 5-3) using 6mm hex key. 3. Tighten screws firmly. 1. Loosen set screw on outer collar (shown in Figure 5-4) with 4mm hex key.
The bed extension can be mounted to the upper or lower holes of the lathe at tailstock end, and lower holes at headstock end. Mounting in upper holes increases spindle length capacity of lathe. Mounting extension to lower holes allows use of tool support during outboard turning. 1. Install comparator spur center into guard bracket, by lifting up on plunger and inserting comparator spur center until its point is about even with the point of the spur center in the headstock spindle. See Figure 5-7.
6.0 Electrical connections 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. Electrical connections must be made by a qualified electrician in compliance with all relevant codes.
7.0 Adjustments 6. 7.1 Headstock movement Always engage locking handle (A) before operating lathe. 7.1.1 Sliding Rotate knob (B) clockwise until it engages the threads. 7.2 Tailstock movement Push handle (A, Figure 7-1) downward to unlock. Headstock will slide freely along length of bed. Push handle up to lock. To slide tailstock, push locking handle (C, Figure 73) down toward bed. Push handle up to lock tailstock in position. Always lock headstock in position before operating lathe.
Make sure the clamp bushings (K) are pulled apart sufficiently to accept tool rest post. 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. Figure 7-6 7.7 Locking handles Locking handles, such as H, Figure 7-5, are adjustable.
To remove a live center: 4. Back off tailstock and remove workpiece from lathe. 5. Loosen quill lock handle (M). 6. Rotate handwheel counterclockwise to retract quill all the way, until live center comes out. Hold the center while doing this to prevent it from falling. Figure 7-7: index pin 7.9 Spur center: Installing/removing The spur center is installed into the headstock spindle. The center should first be mounted to your workpiece, and then installed into the spindle. See section 9.4. 1.
4. If centers do not align, unlock headstock and pivot it slightly. There should be enough “play” in headstock to adjust for this alignment. Lock headstock when finished. 7.15 Speed Range Adjustment (JWL1840EVS only) See Figure 7-13. Figure 7-11: spindle lock and face plate 1. Disconnect lathe from power source. 2. To change speed range, open access door on headstock. 3. Loosen pivot lock handle (A, Figure 7-13) and lift up tension handle (B) to raise motor.
8.0 Operating controls Forward/Reverse (F) See Figures 8-1,8-2. JWL-1840EVS: Switch can be moved while lathe is running. Machine will slow to a stop, then reverse direction. On/off switch (C): Pull to start lathe, push to stop. The safety key (C1) can be removed to prevent unauthorized use of lathe. The safety key must be inserted to restart the lathe. JWL-1840DVR: In normal mode, forward/reverse switch can be moved while lathe is running. Machine will slow to a stop, then reverse direction.
Main switch (G): Turn on to activate DVR controls. 1. Mode-selection switch (H): Select normal mode or education mode. Education mode provides additional features which are explained below. Level your machine; use the leveling feet to help reduce vibration. 2. Check bearings; adjust only if endplay exists. 3. Check belt; it should be snug but not overly tight. 4. Bed ways; keep clean, use steel wool to remove any rust spots, and apply paste wax to prevent buildup of rust and finishes. 5.
9.4 Stock Selection Stock for spindles should be straight grained and free of checks, cracks, knots and other defects. It should be cut 1/8" to 1/4" larger than the finished diameter and may require additional length so the ends can be removed later. Larger stock should have the corners removed to produce an octagon making the piece easier to rough down to a cylinder. 1. With a combination square, or plastic center finder for round stock, locate and mark center on each end of the workpiece.
Figure 9-5 9.5 Cutting Techniques Figure 9-4 4. Make sure headstock is locked to lathe bed. 5. Clean tapered end of spur center and inside of headstock spindle. 6. 9.5.1 Roughing Out 1. Insert tapered end of spur center (with the attached workpiece) into headstock spindle. Begin with a large roughing gouge. Place the tool on the tool rest with the heel of the tool on the surface to be cut. 2. 7.
9.5.2 Beads 1. Make a parting cut for what is to be a bead to the desired depth. Place the parting tool on the tool support and move tool forward to make the full bevel of the tool come into contact with the workpiece. Gently raise handle to make cut to the appropriate depth. 2. Repeat for other side of the bead. 3. Using a small skew or spindle gouge, start in the center between the two cuts and cut down each side to form the bead. Roll the tool in direction of cut. Figure 9-8 9.5.3 Coves 1.
9.6.1 Mounting Stock 9.6.2 Faceplate or Chuck? Use of a face plate is the most common method for holding a block of wood for turning bowls and plates: While faceplates are the simplest, most reliable method of holding a block of wood for turning, chucks can also be used. As there are dozens of chucks to choose from, the woodturner should first consider all the different types of turning that will be done, and read reports or discuss with other turners who own chucks before making a decision. 1.
10. Finish turning the outside of bowl with 1/2" or 3/8" bowl gouge. Leave additional material at base of bowl for support while turning interior. This will be removed later. other gouges. Most average sized bowl work can be accomplished with a 3/8" or 1/2" bowl gouge. A 1/4" bowl gouge is best suited for smaller bowls and light finishing cuts. Larger 3/4" and 1" bowl gouges are only used for extremely large pieces. Large domed scrapers can also be used to help clean up the interior surfaces of bowls.
9.7.3 Sanding and Finishing 1. Remove the tool support and adjust lathe speed to approximately 500 RPM. Higher speeds can build friction while sanding and cause heat check in some woods. 2. Begin with fine sandpaper (120 grit) and progress through each grit, using only light pressure. Coarser sandpaper tends to leave deep scratches that are hard to eliminate. Use power-sanding techniques to avoid concentric sanding marks around your finished piece.
or take the headstock to an authorized service center. 10.0 User-maintenance 1. Disconnect lathe from power source. 2. Loosen pivot lock handle (A, Figure 9-12) and lift up tension handle (B) to raise motor. 3. Tighten pivot lock handle (A) to secure motor in raised position. 10.1 General procedures 4. Slip belt off pulleys.
