Warning

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 the warning labels if they become obscured or removed.

4. This jointer 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 jointer, do not use until proper training and knowledge have been obtained.

5. Do not use this jointer 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 approved safety glasses/face shields while using this jointer. Everyday eyeglasses only have impact resistant lenses; they are not safety glasses.

7. Before operating this jointer, remove tie, rings, watches and other jewelry, and roll sleeves up past the elbows. Remove all loose clothing and confine long hair. Non-slip footwear or anti-skid floor strips are recommended. Do not wear gloves.

8. Wear ear protectors (plugs or muffs) during extended periods of operation.

9. Do not operate this machine while tired or under the influence of drugs, alcohol or any medication.

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

11. Make certain the machine is properly grounded.

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

13. Remove adjusting keys and wrenches. Form a habit of checking to see that keys and adjusting wrenches are removed from the machine before turning it on.

14. Keep safety 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.

15. Make sure the jointer is firmly secured to the stand or a bench before use.

16. Check damaged parts. Before further use of the machine, 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. A guard or other part that is damaged should be properly repaired or replaced.

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

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

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

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

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

22. Maintain a balanced stance at all times so that you do not fall or lean against the knives or other moving parts. Do not overreach or use excessive force to perform any machine operation.

23. Use the right tool at the correct speed and feed rate. Do not force a tool or attachment to do a job for which it was not designed. The right tool will do the job better and safer.

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

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

26. Turn off the machine and disconnect from power before cleaning. Use a brush or compressed air to remove chips or debris — do not use your hands.

27. Do not stand on the machine. Serious injury could occur if the machine tips over.

28. Never leave the machine running unattended. Turn the power off and do not leave the machine until it comes to a complete stop.

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

2. Set packing material and shipping cartons to the side. Do not discard until machine has been set up and is running properly.

3. Clean all rust protected surfaces (bed, fence, etc.) with kerosene or diesel oil.

Do not use gasoline, paint thinner, mineral spirits, etc. These may damage painted surfaces.

Cutterhead knives are dangerously sharp!

Use extreme caution when cleaning.

4. Apply a thin layer of paste wax to the bright surfaces of the fence and tables to prevent rust.

Installing Bed to Stand

1. Use an assistant or hoist mechanism to place bed assembly on top of stand. Be sure identification label on the bed faces the same direction as the label on the stand (Fig. 1).

2. Line up two holes in top of stand with holes in bed assembly by viewing through access door in stand.

3. Attach bed assembly to stand with two 3/8" lock bolts and lock washers (Fig.

2). Hand tighten only at this time.

4. Line up third hole in stand with hole in bed assembly by viewing through dust chute.

5. Install third 3/8" lock bolt and lock washer through dust chute to secure bed to stand.

6. Tighten all three mounting bolts with 14mm wrench.

Figure 1

Figure 2

Installing Pedestal Switch (JWJ8HH only)

Referring to Figure 3:

1. The switch may be installed in either high position or low position to suit the operator. Slide the connection plug through the opening (A) and secure the pedestal switch using two 5/16”x3” screws (C) and 5/16” flat washers (B).

2. Connect the plug from the pedestal switch to the motor plug inside the cabinet.

Figure 3

Installing Handwheels

1. Remove protective tape from shaft, and remove screw and washer.

2. Press handwheel (A, Fig. 4) onto shaft, aligning the keyway with the key. If necessary, use a hammer with a block of wood to tap the handwheel completely onto the shaft.

3. Re-install screw and washer (B, Fig. 4).

4. Mount handle (C, Fig. 4) onto handwheel.

Assembling Knife-Setting Gauge (JWJ-8CS only)

Place the two bases (A, Fig. 5) onto each end of the bar (B, Fig. 5). Snap the four Erings (C, Fig. 4) into the grooves on the bar as shown, one E-ring on each side of a base.

Installing V-Belts

1. Disconnect the machine from the power source, unplug.

2. Remove the lock knob (A, Fig. 6) and belt guard (B, Fig. 6).

Figure 4

Figure 5

3. Place v-belts onto cutterhead pulley grooves and through opening in stand.

4. Pull v-belts down and place onto motor pulley (Fig. 7). If necessary, loosen the mounting screws (A, Fig. 7) and slightly lift motor. Re-tighten the screws when belt is placed.

5. Check to make sure that motor pulley and cutterhead pulley are vertically aligned and the v-belt does not contact the sides of the opening in the base. If the pulleys are not aligned, loosen the screws (A, Fig. 7) on the motor base and slide the motor until the belt is aligned. Re-tighten screws.

6. The v-belt is properly tensioned when finger pressure on the belt half way between the two pulleys causes 1/2" deflection. If the belt is too loose, loosen the lower screws (B, Fig. 7) on the mounting plate and push down on the plate. When belt tension is correct, re-tighten screws.

7. After two hours of operation, check belt tension again. Re-tension if necessary.

8. Re-install belt guard and lock knob.

Figure 6

Figure 7

Installing Cutterhead Guard

The cutterhead guard has a spring tension mechanism which must be properly tensioned when installing the cutterhead guard on the machine.

To install the cutterhead guard:

1. Insert a small hex wrench, or similar object, into the pin on the guard tension mechanism (Figure 8-1).

2. Twist the hex wrench and pin clockwise, as shown in Figure 8-2, and hold them there.

3. Lower the shaft of the guard into the hole on the jointer’s rabbeting ledge. See Figure 8-3. The guard should be lowered into the hole far enough that the groove in the guard’s shaft will mate with the shaft of the set screw (Figure 8-3).

4. After the guard has been inserted into the hole, let go of the guard with your left hand - the guard will swing toward the fence.

Figure 8-1

5. Completely tighten the set screw (Figure 8-3), while continuing to hold the hex wrench and pin with your right hand.

6. When the guard is secured, remove the hex wrench from the pin. Slightly loosen the set screw (Figure 8-3) until the pin snaps back against the rabbeting ledge.

7. Re-tighten the set screw (Figure 8-3).

Installing Access Door

Install access door by placing bottom of panel into access in stand and fastening by turning latch (Fig. 9).

If the access door latch needs adjustment:

1. Remove the access door from the stand.

2. Loosen the hex lock nut (A, Fig. 9). Rotate the latch a quarter turn clockwise to tighten and counterclockwise to loosen.

Figure 8-2

Figure 8-3

3. Tighten the lock nut (A, Fig. 9).

4. Re-install the access door.
