25. Mai ntain tools with care. K eep knives sharp and clea n for the best and saf est performance. Foll ow

instructions for lubricating and changing accessories.

26. Turn off the mac hine before cl eaning. Use a brush or compressed air to remov e c hi ps or debris — do

not use your hands.

27. Do not stand on the machine. Serious i nj ur y c ould oc c ur if the mac hine tips over.

28. Never leave the machine r unning unatt ended. Turn the power off and do not leave t he machine until

the cutterhead c omes to a complete stop.

29. Remove loose items and unnecessary work pieces from the area bef or e starting the machine.

30. Nev er surface stoc k less than 12 inc hes long, or 3 inches wide, or 3 inc hes thick wit hout a hold- down

or push block.

31. When working on the jointer, follow the 3-inch

radius rule. The hands must never be closer than 3 inches to the cutt er head. See Figure A.

32. Use ext ra care in the location of the jointer in the

shop. Position the jointer so that potential kicked back stock will strike a wall and not endanger other persons in t he ar ea.

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. Follow the 3-inch rule. Position hands away from extreme ends of stock, and push through with a smooth, even motion.

34. “Pull -out ” and the danger of ki ck ed back stock can

occur when the work piece has knots, holes, or foreign materials such as nails. It can also occur when the stock is fed against the grain on the jointer. T he grain shoul d run in the sam e directi on you are cutting.

35. It is good practice to move the hands in an

alternate motion from back to front as the work continues through the cut. Nev er pass t he hands directly over the cutter knife. As one hand approaches the kniv es, rem ove it from the stoc k in an arc motion and pl ace it back on the stock in a position beyond t he cutter knife. See Figure B. At all times hold the stock firmly.

or operation! Failure t o co mpl y may cause seri ou s injury.

Assembly

Tools need for assembly:

10mm hex wrench (provi ded) 10-12mm combi nation wrench (provided) forklift or hoist with straps cross-point screwdriver

1. Remove top and sides of crat e from around

the machine.

2. Remove the dust hood and the fence

assembly from the skid. Reach into the stand and remov e the screws securing the stand to the skid.

3. Raise the jointer off the skid with lifting

straps. The straps should be suitable to lift 762 pounds of weight, and shoul d be plac ed under the base casti ng as shown in Figure

1. Do not lift the j ointer under t he infeed and outfeed tabl es.

4. The jointer should be placed on a sturdy,

level floor in a dry area, with sufficient lighting and v entilation. Leave enough room around the machine for loading and offloading stock and routine maintenance work. The mac hine can be f urther stabi lized by bolting it to the floor using lag screws through the holes on the i nsi de of the stand.

5. This machine is equipped with noise-

reducing table lips. The work site should, however, be one which minimizes reverberant sound from walls, ceilings and other equipment.

6. Exposed met al ar eas of the jointer, i ncl uding

the table and fence surfaces, have been factory coated wit h a prot ectant. This should be removed wit h a soft clot h dampened wit h a solvent such as mineral spirits or kerosene. Do not use ga soline, acetone or lacquer thinner , and do not use an abrasive pad. Do not let solvent contact the plastic parts of the machine, as it may damage them.

Figure 1

Fence Installation

1. Use an assistant to help place the fence

assembly on top the table, aligning the holes in the fence assembly with the holes in the table base, as shown in Fi gur e 2.

2. Use the two socket head cap screws and

two lock washers (Figure 2), and tighten securely with a 10mm hex wrench.

Figure 2

Switch Arm

The arm (Figure 3) on which the push button switch is l oc ated is shipped in the down posi tion. The arm should be pivot ed to upright positi on as shown. Tighten the two screws with a 10mm wrench.

Dust Hood

Before attaching the dust hood, make sure the hole in the dust c hute is concealed by the dust chute cover, as shown in Figure 4.

Mount the dust hood to the jointer stand using the seven 1/ 4 x 1/2 hex cap screws and seven 1/4 lock washers (Figur e 5) .

It is recom mended that a dust coll ection system of at least 800 CFM be connect ed to the jointer’s dust hood, via a 6-inc h diam eter hose.

Grounding Instructions

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.

Figure 3

Figure 4

This machine must be grounded. Grounding provides a path of least resi stance to hel p divert current away from the operator in case of electrical malfunction.

Make sure the voltage of your power supply matches the specif ications on the m otor plate of the machine.

Open the junction box (Figure 6) and connect the wires accordi ng t o the di agram on t he inside of the juncti on box c over. A simi lar diagram can be found at the back of this manual . The green wire (ground) m ust be pr operl y gr ounded.

The Model 1285 may be fitted with an appropriate plug, or be “hard-wired” to an electric al panel. If hard-wired to a panel, mak e sure a disconnect is available for the operator.

Figure 5

Figure 6

If the jointer is to be hard-wired, make sure the fuses have been r emoved or the breakers hav e been tripped i n the circuit t o which the saw will be connected. Place a warning placard on the fuse holder or ci rcuit breaker to prev ent it being turned on while the machine is being wired. Always follow proper Lock-Out/Tag-Out procedures when per forming any wiring on thi s machine.

Voltage Conversion

The Model 1285 Jointer is wired for 1-phase, 230 volt only; or 3-phase, 230/460 v olt. The 3phase model i s pre-wired at the f actory for 230 volt. However, if you wish to convert your 3phase joint er from 230 volt t o 460 volt, proceed as follows:

1. Disconnect machine from power source.

2. Remove cover fr om junction box, and open

the side door on the stand.

3. Change the wires in the junction box by

following the diagram on the inside of the junction box cover, or the di agram found at the back of this manual.

4. Replace the 230 volt contactor (see Figure

7) with the 460 volt contactor (stock no. PJ1285-109). The 460 volt contactor is available through your authorized Powermatic distributor, or by calling 1-800274-6848.

5. If you are using a plug on the joi nter’s power

cord, install an appr opr iate 460 volt plug.

6. After wiring f or the new volt age, turn on the

machine and observe the rotation of the cutterhead; it should be clockwise when viewed from the front of machine. If it rotates counterclockwise, disconnect jointer from power source and switch any two of the three wires at t he junc tion box.

7. Close junction box and r ec onnec t power.

Extens ion cords

The use of an extension cord is not recommended, but if one is necessary make sure the cord rati ng i s suit able f or t he amperage listed on the machine’s motor plate. An undersized cord will cause a drop in line voltage resulting in loss of power and overheating.

Figure 7

Use the chart in Fi gure 8 as a general guide in choosing the cor rect size cord. If in doubt, use the next heavi er gauge. The smaller t he gauge number, the heavier the cord.

Figure 8

Adjustments

Disconnect jointer from

power supply before makin g ad ju st ments.

Drive Belt Tension

To check the tension of t he drive belts:

1. Rem ove the thr ee cap nuts and fl at washers

on the pulley cover with a 9/ 16 wrench, and remove the guard to expose the belts and pulleys. S ee Figure 9.

NOTE: The hex nuts and flat washers on the threaded rods (A, Figure 9) should be left in place; they keep t he pulley cover from bending as it is being ti ghtened back into place with the cap nuts.

2. There should be a small amount of

deflection in the belt when pressing it midway between the pul leys with moderate finger pressure (Figure 10).

3. If the belts need ti ght ening, loosen the l ower

hex nut (A, Figure 11) on the motor base with a 19mm wrench.

Figure 9

4. Turn the top hex nut (B, Figure 11)

clockwise until proper tension is achiev ed.

5. Retighten lower hex nut (A, Figure 11). NOTE: The belts should be inspected again

after the first f ew times the machine is used, as the belts may stretch slightly during the “breaking-in” process.

Setting Outfeed Table Height

For accurate work in most jointing operations, the outfeed tabl e must be exactly level with the knives/insert s at thei r highest poi nt of rev olution. The outfeed table on t he Model 1285 has been pre-set at the factory to the proper height in relation to t he cutterhead. Howev er, the level of the outf eed table should be checked i n case of slight misadjustment during shipping. Outfeed table height should also be inspected after resetting or replac ing knives/inserts.

1. The outfeed table has a stop screw (A,

Figure 12) whic h, when contact ing the edge of the table as shown, will ensure the outfeed tabl e is at the proper height . Loosen the handwheel (C, Figure 12) and raise the outfeed tabl e adjustment arm (D, Figure 12) until thi s stop screw (A, Fi gure 12) contact s the edge of the table as shown.

Figure 10

Figure 11

Figure 12

2. Place a straight edge on the outfeed table

and extending over the cutterhead, as shown in Figure 13.

3. Rock the cut terhead slightly so that a knife

tip contacts the st raight edge. If the knif e tip just contacts the straight edge without moving the straight edge, then the outfeed table is at the pr oper height. If the knife tip pushes up the straight edge, the outfeed table is too low. If the knife tip does not contact the str aight edge, the outfeed tabl e is too high.

4. To raise the height of the outfeed table,

loosen the hex nut (B, Fi gure 12) and rotate the stop scre w (A, Figure 12) cl ockwise. To lower the height of the outfeed table, rotat e the stop screw (A, Figure 12) counter clockwise.

5. When the outfeed table is level with the

knives, tighten the hex nut (B, Figure 12) and firmly tighten the handwheel (C, Figure

12).

After the outfeed table has been set, it should not be changed except f or speci al operations.

As a final check of the outf eed tabl e adjustment , turn on the jointer and run a scrap piece of wood slowly over the knives for 6 to 8 inches; the wood should rest firmly on both tables, as shown in Fi gure 14, with no open space under the finished cut.

If the outfeed table is too high, the finished surf ace of the workpiece will be curved (Figure

15).

Figure 13

Figure 14

Figure 15

If the outf eed tabl e i s too l o w, the workpiece wil l be gouged at the end of the cut (Fi gur e 16) .

Make further changes to the stop screw if necessary to ensure the outfeed table is level with the knives/inserts.

Figure 16

Setting Infeed T able Height (Depth of Cut)

1. To set t he cutting depth, loosen handwheel

(A, Figure 17) by turning counterclockwise.

2. Move table adjustment arm (B, Figure 17)

up or down to raise or lower infeed table. The pointer (C, Figur e 17) shows the depth of cut on the adjoining scale.

3. Tighten handwheel securely (A, Figure 17). The stop screw (D, Figure 17) on the infeed

table should be set so that when it cont acts the table, t he infeed table will be ex actly level with the knives (wit h the scale pointer at zero). The setting of this stop screw has bee n made at the factory, but should be checked by the operat or before using the jointer. It should also be checked occasionally as the machine receives use.

Use the same procedure as for the outfeed table, placing the straightedge across outfeed table, cutterhead and infeed table. Loosen the hex nut (E, Figure 17) and adjust t he stop screw (D, Figure 17) as necessary. When finished, retighten hex nut (E, Figure 17).

If the infeed t abl e is lev el wit h the kniv es but the scale pointer (C, Figure 17) appears to be off, loosen the scale poi nter with a screwdriv er and adjust it as needed unti l it reads zero. Ret ighten the screw.

Replacing and Setting Knives (Straight Cutterhead)

Figure 17

Jointer knives are very

sharp. Use care and proceed slowly when working with or around the cu t t erhead .

After a period of use, dull knives should be reground or repl aced. Remove the pul ley cover at the rear of the machine – this will allow you to rotate the cutt erhead by using the belts.

To remove a knife:

1. Disconnect machine from power source.

2. Back the f ence away f rom the cutt erhead as

far as it will go. Lower infeed and outfeed tables.

3. Tur n the six gib screws (Figure 18) into t he

gib with a 10mm wrench. A s the pressure of the gib is released, the two springs in the cutterhead slot wil l c ause the k nife to rise.

4. Carefully remove the knife from the

cutterhead.
