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. 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 other 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 machine is properly grounded.

12. With the exception of feed rate adjustment, make all machine adjustments or maintenance with the

machine disconnected from the power source. A machine under repair should be RED TAGGED to show it should not be used until the maintenance is complete.

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. Check damaged parts. Before further use of the machine, a guard or other part that is damaged

Installation and Assembly

Tools Required for Installation:

Forklift or hoist, with lifting straps 4mm hex wrench (provided) 22mm combination wrench (provided)

Remove any straps or boards holding the planer to the pallet. Place straps under the four lifting hooks at front and back to raise the planer off the pallet and move it to location.

Make sure the straps will not

damage buttons or levers on the front of the planer.

The planer should be installed on a solid foundation, preferably a concrete floor. The machine area should be clean, dry, well ventilated, and well lit. Since planers can create noise problems, the site selection should be one which minimizes reverberant sound from walls, ceilings and other equipment. Electricals should be installed so that they are protected from damage and exposure. Be sure to properly ground the machine.

Lower the leveling screws, and place the four foot pads beneath the leveling screws. See Figure 1. Lower the machine slowly onto the foot pads. The screws can be turned as necessary until the planer table is level. Tighten the hex nuts against the base to secure the screw settings.

Exposed metal parts have been coated with a rust preventative. This should be removed with a soft cloth moistened with kerosene or a good commercial cleaner/degreaser. Do not use an abrasive pad, and do not get solvents near plastic parts or painted areas.

Figure 1

Dust Hood

Use a 4mm hex wrench to mount the dust hood to the planer with eight M6 x 12 button head socket screws, eight M6 lock washers and eight M6 flat washers, as shown in Figure 2.

It is strongly recommended that a dust collection system be used with this machine. It should be of sufficient volume for this size planer. If a dust collector is not used, the user is cautioned against the health hazard and the limitations in the OSHA regulation for employee or student exposure to dust particles.

Figure 2

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.

This machine must be grounded. In the event of a malfunction or breakdown, grounding provides a path of least resistance for electric current to reduce the risk of electric shock.

Improper connection of the equipmentgrounding conductor can result in a risk of electric shock. The conductor with insulation having an outer surface that is green with or without yellow stripes, is the equipmentgrounding conductor. If repair or replacement of the electric cord or plug is necessary, do not connect the equipment-grounding conductor to a live terminal.

Check with a qualified electrician or service personnel if the grounding instructions are not completely understood, or if in doubt as to whether the tool is properly grounded.

Repair or replace a damaged or worn cord immediately.

Make sure the voltage of your power supply matches the specifications on the motor plate of the Planer. The machine should be connected to a dedicated circuit.

The use of an extension cord is not recommended for the WP2510 Planer.

230 Volt Operation

The Planer is factory wired for 230 volt, but can be converted to 460 volt if so desired (see “Converting From 230 Volt to 460 Volt”). You may either install a plug or “hard-wire” the Planer directly to a control panel.

If you are connecting a plug, use a proper UL/CSA listed 3-pole, 4-wire grounding plug suitable for 230 volt operation.

If the Planer is to be hard-wired to a panel, make sure a disconnect is available for the operator.

During hard-wiring of the Planer, make sure the fuses have been removed or the breakers have been tripped in the circuit to which the Planer will be connected. Place a warning placard on the fuse holder or circuit breaker to prevent it being turned on while the machine is being wired.

Converting from 230 Volt to 460 Volt

Consult the diagrams on pages 54 and 55 for specific information on the following changes.

1. Disconnect machine from power source.

2. Change the lead connections to the main motor and to the table hoist motor.

3. Replace the RA-30 (230V) overload relay with the provided RA-30E (460V) overload relay.

4. Switch the “R” wire on the transformer from the 230V to the 460V terminal.

5. If using a plug, install a proper UL/CSA listed plug suitable for 460V operation.

Test Run

After wiring has been completed, confirm that the wires have been connected properly:

1. Connect machine to power source and press the “Main Motor” button for just an instant, then press the Stop button.

2. The cutterhead should rotate clockwise as viewed from the handwheel side of the machine. If cutterhead rotation is incorrect,

disconnect machine from power source

and switch any two of the three wires at "R,S,T" (see “Electrical Connections”, pages 54 and 55).

3. Re-connect machine to power source.

Controller Set-Up

To program settings in the Controller for table movement, refer to the section beginnning on page 20.

Adjustments

Depth of Cut

Depth of cut is adjusted by raising or lowering the table using the elevating handwheel or the push buttons for rough positioning; or the keypad on the Controller. The Controller is used for very precise positioning and for remembering your settings (for more information on the Controller see the section beginning on page

20).

To move the table with the elevating handwheel (Figure 3), push the handwheel in to engage the sprocket on the table elevating mechanism. One revolution of the handwheel equals 1/32” change in table height. Use the scale or digital readout to determine distance from the cutterhead.

Figure 3

Feed Rate

The planer is equipped with selectable feed rate rollers that feed stock at 20, 25 or 30 feet per minute. To adjust speed, rotate the lever shown in Figure 4.

IMPORTANT: Change feed rate only while the machine is running.

Belt Tension

1. Disconnect machine from power source.

2. Remove the lower rear panel and use the four hex nuts on the motor mount to adjust belt tension. See Figure 5. Adjust motor plate up or down until correct belt tension is achieved. To lower the motor plate, loosen lower nuts and tighten upper nuts. To raise the motor plate, do the opposite.

3. Correct tension is obtained when there is approximately 1/4” deflection in the center span of the belt using light finger pressure.

4. Re-tighten hex nuts and install lower rear panel.

Figure 4

Opening Hood

To open the hood for access to the cutterhead, remove the two shoulder screws (Figure 4).

NOTE: The planer has a limit switch which prevents operation while the hood is open.

Knife Inserts

Knife inserts are extremely

sharp. Use caution when working with or around the cutterhead.

The knife inserts are four-sided. When dull, simply remove each insert, rotate it, and reinstall it. To maintain quality of cut, replace or rotate all inserts at the same time.

If one or more knife inserts develops a nick, rotate only those inserts that are affected.

An air-operated screwdriver has been provided to speed up the setting of inserts and to ensure the proper torque to seat the inserts securely in the cutterhead. Assemble the regulator valve (Figure 6) and connect it to the air supply and to the air-operated screwdriver. The valve can be mounted to a surface using screws (not provided) through the slots in the bracket. Pull up the knob and rotate to adjust pressure; push the knob down to secure the setting.

Figure 5

Figure 6

1. Disconnect machine from power source.

2. Remove the top left side panel so that you can rotate the cutterhead using the belts.

3. To remove a knife insert, unscrew the flat head screw with a spline screwdriver, or the air-operated screwdriver using one of the provided T-20 spline bits. If the screw will not budge, place the hole of the breaker rod (A, Figure 7) over a spline bit (B, Figure 7) and lightly tap the breaker rod counterclockwise with a hammer to break loose the screw.

4. Remove the flat head screw, and remove the knife insert.

5. Carefully wipe clean the insert seat on the cutterhead and install the new knife insert (or rotate the present one).

6. The knife insert should be “pre-set” and then given a final tightening. Install the flat head screw, and turn the screw until the knife insert is snug. To pre-set, you may use one of the spline screwdrivers provided, or use the air-operated screwdriver set at 45 psi.

7. When finished pre-setting the knife insert, set the air operated screwdriver to 85 psi, and fully tighten the screw.

Figure 7

8. Repeat for all knife inserts.

Make sure all knife inserts

are secure in the cutterhead. Failure to comply may allow knife inserts to loosen and be flung from the machine during operation.

The Planer’s Feed System

(Figure 8)

1. Anti-Kickback Fingers

2. Infeed Roller

3. Chipbreaker

4. Cutterhead

5. Pressure Bar

6. Outfeed Rollers

Anti-Kickback Fingers

Anti-kickback fingers help prevent stock from being thrown from the machine. These fingers operate by gravity and should be inspected for pitch or gum buildup before each day’s use. The fingers must operate freely and move independently for correct operation.

Infeed Roller

The function of the infeed roller is to feed the material into the machine. It is a corrugated, sectional roller with approximately 1/4” independent movement of each section to accomodate multiple board surfacing.

Figure 8

To provide proper drive, the infeed roller should be set so that the bottom of its arc is 1/16” below the arc of the cutterhead knife inserts. The infeed roller is under spring tension and this tension must be sufficient to feed the stock uniformly through the planer without slipping but should not be so tight that it causes damage to the boards. The tension should be equal at both ends of the roller.

To adjust the infeed roller:

1. Disconnect machine from power source.

2. Place a dial gauge under a knife insert in the cutterhead. (Figure 9 shows a Bed and Feed Roll Gauge – accessory #2230002 – which can be purchased from your dealer. )

If a dial gauge is not available, use a finished block of wood with notches cut out for the table rollers, in conjunction with a feeler gauge. See Figure 10 for an example of a wood block you can make and use as a gauge.

3. Raise the table with the handwheel until the gauge contacts a knife insert at the apex of its curve. Zero the gauge at that position.

Figure 9

4. Move the gauge to the extreme left side of the infeed roller and check the measurement. It should be 1/16” below the knife measurement.

5. If it is not 1/16”, correct by loosening the hex nut (A, Figure 11) and turning the adjustment screw (B, Figure 11) with a hex wrench.

6. Move the gauge to the extreme opposite end of the infeed roller and check. Make necessary adjustments. Tighten hex nuts (A, Figure 11) when finished.

IMPORTANT: The setting on both sides of the infeed roller must be the same to avoid skewing of the material as it is fed through the machine.

Chipbreaker

The chipbreaker (C, Figure 11) is a sectionalized type made of spring-loaded sections mounted on a bar, which complements the sectional infeed roller. The functions of the chipbreaker are to break chips into small pieces, help avoid splintering of the wood, help avoid board bounce on thinner boards, to direct the flow of chips out of the machine, and to permit multiple board surfacing.

Figure 10

User-made Gauge Block

The chipbreaker has been factory set at 1/32” below the cutting arc of the knives, and has been spring-tensioned properly.

Figure 11

A chipbreaker set too low or

with excessive tension may prevent stock from feeding into the machine.

Pressure Bar

Most planing problems can be traced to improper setting of the pressure bar. Its function is to hold down the material after it passes under the cutterhead and throughout the remainder of the cut. Its basic setting is to be in line with the arc of the cutterhead knives.

If it is too high, a shallow “clip” will occur at each end of the board. If it is too low, stock will not feed through.

Use a gauge to set the full length of the pressure bar to be .000-.001” (.02mm) below the arc of the cutterhead. Figure 11 shows the height adjustment screw (D) and the spring tension adjustment screw (E) for the pressure bar. This initial setup is a starting point and final adjustment may have to be made during a test cut.

Outfeed Rollers

The two outfeed rollers are of smooth, one-piece construction to help avoid marring the finished surface of the material being cut. Their function is to continue to feed the material through the machine after it leaves the infeed roller. The correct free position setting is 1/32” (.8mm) below the arc of the cutterhead knives.

Use a gauge, such as a bed and feed roll gauge or wood gauge block, to check the outfeed rollers in the same manner as the infeed roller.

Adjust as necessary using the screws (F, Figure

11). When finished adjusting, tighten the hex

nuts on the screws (F, Figure 11).

Table Rollers

The Planer has two table rollers which help reduce friction of the stock on the table as it feeds through the machine. It is not possible to give exact height setting of the table rollers because each type of wood behaves differently. As a general rule, however, the table rollers should be set high when planing rough stock, and set low for finish cuts.

The planer is equipped with a quick-set table roller adjustment. With a single lever, you can raise the rollers from their finishing board height to a roughing board height. See Figure 12. The range is 0.00 to 0.05”.

To adjust the height of the table rollers, loosen the lock handle (Figure 12) and turn the quickset lever. Re-tighten the lock handle to lock the setting.

Figure 12

The table rollers are adjusted at the factory. If they should need further or “fine” adjustment:

1. Disconnect machine from power source.

2. Loosen lock handle and position the quickset lever (Figure 12) to zero.

3. Use a dial gauge (not provided) to find the distance from table top to the apex of the table roller. Zero the gauge at this position.

4. Place the gauge over the extreme right side of the table roller and find the high point of the table roller arc. The gauge should still read zero.

5. If the gauge reading is greater or less than zero, reach beneath the table with a wrench and loosen the hex nut (C, Figure 13) which is above the cam (D, Figure 13) near the end of the roller that needs adjusting. Rotate the hex cap screw (E, Figure 13) until the gauge reads zero.

6. Repeat the process for the left side of the table roller, and then recheck the right side. It is important that both ends of the table rollers be the same height to help prevent skewing of the board as it feeds through the machine.

7. Re-tighten the hex nuts (C, Figure 13) on both ends of the table roller.

8. Repeat the procedure for the second table roller.

Table Adjustments

The planer table is raised and lowered by twin screws supported on bearings, and is guided by machined surfaces on the side panels. The fitup to prevent the table from rocking is controlled by gibs. See Figure 14. These gibs should be adjusted individually using the three gib screws provided so that the ways are lightly contacting on all four surfaces. The gibs should be tight enough to prevent rocking or movement of the table when the planer is in operation.

Figure 13

To perform accurate planing the table must be parallel with the cutterhead. Lack of parallelism results in a taper over the width of the board. To check parallelism do the following:

1. Place a gauge on the table and contacting a knife insert at the apex of its arc, Do this at each end of the cutterhead and compare the measurements.

2. If the table is not parallel to the cutterhead, place the gauge at the end that needs to be raised.

Figure 14

3. Loosen the three socket head cap screws (A, Figure 15) beneath the table.

4. Place a rod-like object (such as a hex wrench) into one of the open holes (B, Figure 15) and turn the shaft (C, Figure 15) to raise the table until the gauge reads the proper measurement. Or, the same effect can be achieved by lowering the other side of the table.

5. Re-tighten the socket head cap screws (A, Figure 15).

Test Cutting and Troubleshooting

Using a piece of semi-finished stock, set up for a 1/16” (1.59mm) deep cut with the quick-set table roller setting at zero. Start the machine and, standing to one side of the table, begin feeding the stock into the machine.

Never stand directly behind

stock or allow anyone else to do so, and do not bend down to see how stock is feeding. Should a kickback occur, serious or fatal injury could result.

The infeed roller should take the material and force it under the chipbreaker and cutterhead. If the material feeds through effortlessly, examine the finished cut carefully for imperfections.

Learning to read a board for imperfections will save hours in adjusting a planer to operate properly.

Following are some problems that may arise and their probable remedies. The illustrations are exaggerated for clarity. (Pages 37-39 also contain Troubleshooting remedies).

Feed Restriction

This is caused either by the table rollers being set too low for roughing operations or from a low pressure bar. About 90 percent of the time, the pressure bar is too low. As the sharp edge of the knife inserts wear, you must compensate for this wear by slightly raising the pressure bar an equal amount on each side. Your first indication of knife wear is hesitation in feed of the material through the machine after it leaves the corrugated infeed roller on its way out of the machine. Disconnect machine from power and adjust the pressure bar accordingly. The material will free up and feed through smoothly when the planer is restarted.

Never attempt pressure bar

adjustment while the machine is connected to power.
