3.0 Safety warnings

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 woodworking Jointer-Planer 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 woodworking jointer or planer, do not use until proper training and knowledge have been obtained.

5. Do not use this machine for other than it s intended use. If used for ot her pu rposes, JET d isclaim s any rea l or implied warranty and holds itself harmless from any injury that may result from that use.

6. Always wear approved safety glasses/face shield while using this woodworking jointer-planer. NOTE: Everyday eyeglasses only have impact resistant lenses; they are not safety glasses.

7. Before operating this woodworking jointer-planer, remove tie, rings, watches and other jewelry, and roll sleeves up past the elbows. D o not wear loose clothing. C onfine long hair. Non-slip footw ear or anti-skid floor strips are recommended. Do not wear gloves.

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

9. 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 oth er 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.

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

11. Make certain the switch is in the OFF position before connecting the machine to the power source.

12. Make certain the machine is properly grounded.

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

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

15. 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.

16. Make sure the jointer-planer is firmly secured to the floor or bench before use.

17. 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 m oving parts, breakage of parts, mounting a nd any other conditions that may affect its operation. A guard or other part that is damaged should be properly repaired or replaced.

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

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

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

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

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

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

24. 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 more safely.

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

26. Maintain tools with care. Keep cutters sharp and clean for the best and safest performance. Follow instructions for lubricating, and changing accessories.

27. Make sure the workpiece is sec urely attached or clamped to the table. Never use your hand to hold t he workpiece.

28. Turn off the machine before cleani ng. Use a brush or com pressed air to remove chips or debris — do not use your hands.

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

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

31. Before turning on machine, remove all extra equipment such as keys, wrenches, scrap, stock, and cleaning rags away from the machine.

Jointer operation

32. Always use a hold-down or push block when surfacing stock less than 12" inches long, or 3 inches wide, or 3 inches thick.

33. Do not perform jointing operations on material shorter than 8", n a rrower than 3/4" or less than 1/4" thick.

34. The hands must never be closer than 3 i nches to the cutterhead (see Fi gur e at right).

35. Never app ly pressure to stock directly over the cutterhead. Thi s may result in the stock tipping into the cutterhead along with the operator's fingers. Position hands away f rom extreme ends of stock, and p ush through with a smooth, even motion. Never back workpiece toward the infeed table.

36. To avoid kickback, the grain must run in the same direction you are cutting. Before attempting to joint or plane, each workpiece must be carefully examined for stock condition and grain orientation.

37. 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.

38. 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.

39. At all times hold the stock firmly against the table and fence.

Planer ope r a t i on

40. Keep hands outside the machine. NEVER reach under the guards to try to clear stock that stops feeding. Do not cl ear chi ps and s awdust wit h hands; use a bru sh. Do not have any part of t he hands under that part of the board t hat is over the table when starting a cut; the inf eed roll will engage the board and forc e it down against t he table causing a pinching acti on.

41. Check stock conditi on. Do not pl ane boards with l oose knots or with nai ls or any f orei gn materi al on its surfac e. Knife impact on t hese objects can cau se the kniv es to be pulled out and cause them t o shatter against the chipbreaker or pressure bar. Twisted, warped, or in wind stock should first be jointed on one surface before attempting to plane a parall el surf ac e on the planer. Serious stock flaws cannot be removed by use of a planer alone.

42. T o avoid kickbac ks, use this machine f or single board surfaci ng only. Never make cuts deeper t han 1/8 inch (3mm).

Familiariz e y our self with the following safety noti c es used in this manual:

This means that if precautions are not heeded, it may result in minor injury and/or

possible machine damage.

This means that if prec autions are not heede d, i t may result i n serious i njur y or possi bly

even death.

10.0 Adjustments

10.1 Table and knife adjustments

For accurat e jointi ng, at least thr ee thi ngs m ust be true:

1. Infeed and outfeed tables must be coplanar.

2. Knives or knife inserts must be set in the

cutterhead so that the highest point of their ar c is level with the outfeed table.

3. On the standard cutterhead, knives must be

parallel with the outfeed table across the entire length of the knives.

These alignments are explained below.

Disconnect machine from power source b efore making any adjust ments. Failure to compl y may cause seri ou s injury.

10.2 Coplanar alignment

Definit io n of c op la na r

When the infeed tabl e is set to the same level as the outfeed tabl e and all points on the t ables lie in the same plane, thus forming a "perfect" flat surface, the t ables are said to be coplanar.

Figure 8

For optim um perform ance of the j ointer , the i nfeed and outfeed tables must be coplanar. If they are not, the fi nished workpiec e may have a slight taper or twist across its jointed width or length.

Determining if t abl es are coplanar

The tables hav e been set coplanar at the factory, but they should be double-checked by the operator. Also, as the machine undergoes use, the tables should be checked occasionally and adjusted if necessary.

The procedure described below uses a steel straight edge to set the tables, which should be accurate enough for most purposes.

Important: The t ables must be locked i n position when performing the following test.

Refer to Figures 8 and 9:

1. Disconnect jointer from power source.

2. Loosen the lock knob (A) and slide the

cutterhead guard ( B , C) to clear the table.

3. Slide the fence assembly back (H, E) as far as

it will go, or remove it from the machine entirely.

4. Rotate the cutterhead to avoid knife

interference.

Figure 9

5. Place a st raight edge (D) ac ross the back of the outfeed table (F ) and ext ending over t he infeed table (G). Note the position of the infeed table

(G). Note the position of the straight edge in Figure 8 with respect to the fence (H).

6. Raise the infeed table (G) until it contacts the straight edge (D).

The straight edge should lie level across both tables. Move the straight edge to the front of the outfeed tabl e as shown i n Fi gure 9 and perf orm t he same test .

If the straight edge does not lie level, the front or back of one of the tabl es must be adjusted t o make the tables coplanar. Proceed as described in Performing t he c oplanar alignm ent (following page).

Performing the coplanar alignment

If alignment is required as determined in the previous section, proceed as follows:

Disconnect machine from

power source before making any adjustmen ts. Failure to comply may cause serious injury.

1. Disconnect power from machine.

2. Unlock both cabinet lock handles (A2,Fig. 10).

3. Raise the table (D) fully upright. Adjustment is performed by means of four

setscrews (B

) that adjust the t abl e pitch and ti lt at

the back (towards the fence) and two hex cap screws (A

) that adjust the table toward the fr ont.

Adjustment c an consist of a front adjust ment, rear adjustment or (more probable) a combination of both.

Rear adjustment

Tools requir ed – 13mm wrench, 4mm hex wrench

1. With a 13mm wrench, loosen three hex cap

screws (B
