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 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 bare 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. Before turning on machine, remove all extra equipment such as keys, wrenches, scrap, stock, and cleaning rags away from the machine.
30. Always use a hold-down or push block when surfacing stock less than 12″ inches long, or 3 inches wide, or 3 inches thick.
31. Do not perform jointing operations on material shorter than 8″, narrower than 3/4″ or less than 1/4″ thick.
32. The hands must never be closer than 3 inches to the cutterhead (see Figure).
33. Never apply pressure to stock directly over the cutterhead. This may result in the stock tipping into the cutterhead along with the operator’s fingers. Position hands away from extreme ends of stock, and push through with a smooth, even motion. Never back workpiece toward the infeed table.
34. To avoid kickback, the grain must run in the same direction you are cutting. Before attempting to joint or plane, each work piece must be carefully examined for stock condition and grain orientation.
35. When working with a swirl grain wood or burls, making it necessary to plane against the grain, use a lesser depth of cut and a slow rate of feed.
36. Move the hands in an alternate motion from back to front as the work continues through the cut. Never pass the hands directly over the cutter knife. As one hand approaches the knives remove it from the stock in an arc motion and place it back on the stock in a position beyond the cutter knife.
37. At all times hold the stock firmly.

For assembly convenience, the item letter designators used throughout the Assemblysection are the same as those used to identify shipping content and hardware.

8.1 Attach support to planer
Attach fence support (E, Figure 8-1) to planer with two M6x16 socket head bolts, flat washers and lock washers.
Insert locking plate assembly (H) into support.
Position plate so that pins are against bottom edge of support.
Secure plate in position with fence sliding handle and spacer (G, Figure 8-1). 8.2 Install dust chute and filter bag
Slide the dust chute onto the end of the chip exhaust. Tighten the pan head screw. See Figure 8-2.

Open the zipper on the bottom of the bag, place the spring inside of the filter bag arm.
Slide the arm with the spring over the dust exhaust port.
Close the zipper. See Figure 8-3.

8.3 Install fence and bracket to planer

Attach fence (B, Figure 8-4) to fence bracket assembly (D) with two M6x20 socket head bolts.
Slide fence and bracket over and onto dovetails of support (E) and locking plate (H, Figure 8-1) Continue to slide fence forward so that the fence is over the planer tables. At this position the edge of the blade guard will rest against the fence, and the entire width of the cutter head is covered. Secure bracket in position with fence sliding handle (G, Figure 8-1).
Insert fence tilting handle with spacer (C, Figure 8-4) through right link and thread into left link.
See Figure 8-5:
Make sure limit plate (A, Figure 8-5) is resting in slot of block (B). Position fence against shaft (D) and lock fence in position with fence tilting handle.
Place a combination square against face of fence and table surface. The fence and table must be at 90° to each other. If not, loosen tilting handle (C, Figure 8-4), loosen hex nut (C, Figure 8-5) and turn shaft (D, Figure 8-5) with a screw driver until fence is square. Secure in position by tightening hex nut (C, Figure 8-5).
Use a bevel gauge or protractor to check 45° inward and outward limit stops. The 45° inward stop (E, Figure 8-5) is the hex head bolt located beneath the shaft. The 45° outward stop is located at the top of the fence.
If adjustment is needed, loosen hex nut, turn hex head bolt to proper position and secure in place with hex nut.

8.4 Mounting brackets
The jointer weighs approximately 72 lbs. when completely assembled. The jointer must be installed in a place with ample lighting and correct power supply.
Make sure there is plenty of room for moving the workpiece through the entire cut. There must be enough room that neither operator nor bystanders will have to stand in line with the wood while using the tool.
Jointer can be installed on a workbench using the provided mounting brackets (A, Figure 8-6).
Secure with bolts, lock washers and hex nuts (not supplied).
The jointer must be bolted to a firm, level surface. Make sure the jointer does not rock and the tables are level.

Operating controls

WARNING Disconnect machine from power source before making any adjustments. Failure to comply may cause serious injury.

Refer to Figure 9-1.
The operating positions of the On-Off switch are located on the front of your jointer.
Push the switch up to turn jointer on and push down to turn the unit off.
The switch has a removable key that allows the unit to be locked in the OFF position.
To activate locking mechanism:
Push the switch (A) to OFF position.
Pull switch key (B).
To deactivate locking mechanism:
Insert and press switch key in the slot on switch.

Adjustments

10.1 Table positioning/depth of cut
The outfeed table (the left hand one when facing the machine) is set to be level with the knives at the highest point in their revolution.
The infeed and outfeed tables are preset at the factory to be aligned with the cutterhead.
Rotate the knob beneath the infeed table (#2, Figure 10-1) to raise or lower the infeed table for desired depth of cut, according to the scale on the front of the table.

10.2 Fence positioning
10.2.1 Forward and back

1. Turn machine OFF.

2. Loosen the fence sliding handle (#1, Figure 10-2).
   Note : The handles are spring-loaded: if you find it necessary to reposition a handle, pull it outwards, turn the handle to the new position, and release it.

3. Slide the fence to the desired position. The fence can be positioned over the blade so that only the desired width of the blade is exposed. Make sure the exposed width matches that of the workpiece.

4. Tighten the fence sliding handle so that the fence is secure.

10.2.2 Bevel angles
The fence can be positioned to joint the wood at any angle from 45° inward to 45° outward.
When “beveling” – cutting the entire edge of a work piece to an angle – several passes may be required due to the depth of cut needed.
“Chamfering” refers to removing only the corner of the edge of the workpiece. Normally a chamfer is made in one pass, so a 1/8 in. (3mm) depth of cut is made.

1. Turn machine OFF.
2. Turn the fence tilt handle counterclockwise to loosen it.
3. Manually tilt the fence to desired angle inward or outward. If you have set up the machine as described in sect. 8.0, the fence will hit the stops inward or outward at 45° and measurement should not be necessary (Figure 10-2). However, it is advisable to confirm the settings with a machinist square, or similar angle gauge before commencing.

10.3 Replacing/rotating knife inserts

WARNING Knife inserts are extremely sharp. Use caution when cleaning or changing. Failure to comply may cause serious injury.
Disconnect jointer from power source/unplug.
The knife inserts on the model JJ-6HHBT are four-sided. When dull, simply remove each insert, rotate it 90° for a fresh edge, and re-install it.
Use the provided star point screwdriver to remove the knife insert screw. See Figure 10-4.
It is advisable to rotate all inserts at the same time to maintain consistent cutting. However, if one or more knife inserts develops a nick, rotate only those inserts affected.
Each knife insert has etched numerals to keep track of the rotations.

IMPORTANT : When removing or rotating inserts, clean saw dust from the screw, the insert, and the cutterhead platform. Dust accumulation between these elements can prevent the insert from seating properly, and may affect the quality of the cut.
Before installing each screw, lightly coat the screw threads with machine oil and wipe off any excess.
Securely tighten each screw which holds the knife inserts before operating the planer. Knife inserts should be torqued to approximately 50 to 55 inch- pounds.
WARNING Make sure all knife insert screws are tightened securely. Loose inserts can be propelled at high speed from a rotating cutterhead, causing injury.

Basic Operation

Note: The Figures are general in nature and may not show your particular jointer model.

11.1 Operating precautions

• Always use sharp cutter knives.
• The jointer fence must securely be locked before machine use.
• Check workpiece for foreign objects (nails, screws) and for loose knots.
• Feed with thicker workpiece end at the front, hollow side downward.
• Plane the stock with the grain, if possible.
• Support long workpieces with roller stands or an assistant.
• Use push block(s) or push stick if possible to keep hands away from cutting area.

11.2 Correct operating position
The operator must be positioned offset to the infeed table, as shown in Figure 11-1.

11.3 Hand placement
WARNING Never pass hands directly over the cutterhead.
At the start of the cut, the left hand holds the workpiece firmly against the infeed table and fence while the right hand pushes the workpiece in a smooth, even motion toward the cutterhead.
After the cut is under way, the new surface rests firmly on the outfeed table. The left hand is transferred to the outfeed side and presses down on this part of the workpiece, at the same time maintaining flat contact of workpiece with fence. The right hand presses the workpiece forward, and before the right hand reaches the cutterhead it should be moved to the work on the outfeed table.
It is strongly recommended that the provided push block and push stick be used whenever possible. See Figure 11-2. These are mandatory when jointing smaller stock.

11.4 Surfacing
The purpose of surfacing (see Figure 11-2) on a jointer is to produce one flat surface. The other side can then be milled to precise, final dimensions on a thickness planer resulting in a board that is smooth and flat on both sides and each side parallel to the other.

• If the wood to be jointed is cupped or bowed, place the concave side down, and take light cuts until the surface is flat.
• Never surface pieces shorter than 12 inches or thinner than 3/8 inch without the use of a special work holding fixture.
• Never surface pieces thinner than 3 inches without the use of a push block.
• Cuts of approximately 1/16″ or less at a time are recommended, which provides for better control over the material being surfaced.
  More passes can then be made to reach the desired depth.

11.5 Direction of grain
Avoid feeding work into the jointer against the grain (Figure 11-3). This may result in chipped and splintered edges.

Feed with the grain to obtain a smooth surface, as shown in Figure 11-4.

11.6 Edge jointing
Jointing (or edging) is the process of creating a finished, flat edge surface that is suitable for joinery or finishing (Figure 11-5). It is also a necessary step prior to ripping stock to width on a table saw.

Never edge a board that is less than 3 inches wide, less than 1/4 inch thick, or 12 inches long, without using a push block.
When edging wood wider than 3 inches lap the fingers over the top of the wood, extending them back over the fence such that they will act as a stop for the hands in the event of a kickback.

CAUTION When workpiece is twice the length of the jointer infeed or outfeed table use an infeed or outfeed support.
To edge a board:

1. Make sure the fence is set to 90°. Double check it with a square.
2. Inspect stock for soundness and grain direction. If the board is bowed (curved), place the concave edge down on the infeed table.
3. Set infeed table for a cut of approximately 1/16 inch.
4. Hold the stock firmly against the fence and table, feed the stock slowly and evenly over the cutterhead, as shown in Figure 11-5.

11.7 Beveling
Beveling an edge is the same operation as edge jointing, except that the fence is tilted to a specified angle.
Make certain material being beveled is over 12 inches long, more than 1/4 inch thick and 1 inch wide.
To bevel:

1. Use a bevel gauge to determine the desired angle. Then set the fence to the same angle.

2. Inspect stock for soundness and grain direction.

3. Set the infeed table for a cut of approximately 1/16.

4. If the board is bowed (curved), place the concave edge down on the infeed table.

5. Feed the stock through the cutterhead, making sure the face of the stock is completely flat against the fence and the edge is making solid contact on the infeed and outfeed tables (Figure 11-6).
   For wood wider than 3 inches – hold with fingers close together near the top of the stock, lapping over the board and extending over the fence.
   For wood less than 3 inches wide – use beveled push blocks and apply pressure toward the fence. Keep fingers near top of push block.

6. Several passes may be required to achieve full bevel.

User-maintenance

12.1 Cutterhead care

WARNING Blades are extremely sharp!
Use caution when cleaning or changing.
Failure to comply may cause serious injury!
The condition of the knife inserts will affect the precision of the cut. Observe the quality of the cut that the machine produces to check the condition of the knives. Dull knives will tear, rather than cut the wood fibers and produce a fuzzy appearance.
When gum and pitch collect on the knife inserts, carefully remove with a strong solvent. Failure to remove gum and pitch build up may result in excessive friction, blade wear and overheating.
When knife inserts become dull, rotate them.
After three rotations, replace them.

12.2 Lubrication
The cutterhead ball bearings are lifetime lubricated and need no further care.
12.3 Belt replacement (drive/fan)

1. Disconnect jointer from power source; unplug.
2. Lay the jointer on its side so that the switch is facing upward. See Figure 12-1.
3. Remove the two screws that hold the belt cover in place and remove cover situated at the end of the cutter head.
4. Remove the four screws that hold the bottom cover on and remove cover.
5. Remove the fan belt (B, Figure 12-1) from the cutter head pulley first, then the drive belt. Pull the belt towards you and turn the belt at the same time until it rolls off the pulleys.
6. Install new drive belt, then fan belt, by rolling them onto the pulleys while turning the belts. Make sure belts seat fully in groves of both pulleys.
7. Reinstall covers.

Troubleshooting
