ADDITIONAL SPECIFIC SAFETY RULES

POWER SOURCE

This saw is equipped with a 15-amp motor for use with a 120-volt, 60-HZ alternating current.

For voltage, the wiring in a shop is as important as the motor’s rating. A line intended only for lights may not be able to properly carry the current needed for a power tool motor; wire that is heavy enough for a short distance may be too light for a greater distance; and a line that can support one power tool may not be able to support two or three. A separate electrical circuit should be used for your machines. This circuit should not be less than #12 wire and should be protected with a 20-amp time lag fuse and/or circuit breaker. If an extension cord is used, use only 3-wire extension cords which have 3-prong grounding-type plugs and matching receptacle which will accept the machine’s plug. Before connecting the machine to the power line, make sure the switch(es) is in the “OFF” position and be sure that the electric current is of the same characteristics as indicated on the machine. A substantial voltage drop will cause a loss of power and overheat the motor. It may also damage the machine.

DANGER: DO NOT expose the machine to rain or operate the machine in damp locations.

GROUNDING INSTRUCTIONS

DANGER: This machine must be grounded while in use to protect the operator from electric shock.

All grounded, cord-connected machines:
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. This machine is equipped with an electric cord having an equipment-grounding conductor and a grounding plug.
The plug must be plugged into a matching outlet that is properly installed and grounded in accordance with all local codes and ordinances.
DO NOT modify the plug provided – if it will not fit the outlet, have the proper outlet installed by a qualified electrician.
Improper connection of the equipment-grounding conductor can result in risk of electric shock. The conductor with insulation having an outer surface that is green with or without yellow stripes is the equipment-grounding 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 machine is properly grounded.
Use ONLY 3-wire extension cords that have 3-prong grounding type plugs and matching 3-conductor receptacles that accept the machine’s plug.
Repair or replace damaged or worn cord immediately

DANGER: In all cases, make certain that the receptacle in question is properly grounded. If you are not sure, have a qualified electrician check the receptacle.

EXTENSION CORDS

DANGER: NEVER use a damaged extension cord. Check extension cords before each use. If damaged, replace immediately.
Touching the damaged area could cause electrical shock resulting in serious injury.

CAUTION: KEEP the extension cord clear of the work area. Position the cord so it will not get caught on lumber, tools or other obstructions

WARNING: Use proper extension cords. Make sure your extension cord is a 3-wire extension cord which has a 3-prong grounding type plug and matching receptacle which will accept the machine’s plug. When using an extension cord, be sure to use one heavy enough to carry the current of the machine. An undersized cord will cause a drop in line voltage, resulting in loss of power and overheating. The table below shows the maximum gauge to use depending on the cord length. If in doubt, use the next heavier gauge. The smaller the gauge number, the heavier the cord. ONLY round, jacketed cords listed by Underwriter’s Laboratories (UL) should be used.

** Ampere rating (on tool data label)

12A- 16A

Cord Length| Wire Size
25′| 14 AWG
50′| 12 AWG
** Used on 12 gauge – 20 amp circuit

NOTE: AWG = American Wire Gauge

HOW TO FASTEN THE PLANER TO A SUPPORTING SURFACE

CAUTION: Before operation, secure the planer to the supporting surface. Four holes (two of which are shown at A Figure 9) are provided for this purpose.
CAUTION: Operate the planer on a flat, level surface.

Four attachment holes are provided for mounting the planer to a stand or work surface. These holes are located under the in-feed and out-feed tables as shown in Figure 9

OPERATION

OPERATIONAL CONTROLS AND ADJUSTMENTS

How to Start and Stop the Planer

To turn the planer “ON”, lift the paddle F9 . To turn the tool “OFF”, push the paddle down ,as shown in Figure 10.

IMPORTANT: When the machine is not in use, the switch should be locked in the “OFF” position (Figure 11) to prevent unauthorized use. Place a padlock A with a 1/4 inch (6.3mm) diameter shackle through the hole on the left side of the switch cover and through the hole in the switch paddle. Lock the padlock. See Figure 12.
OPERATION

WARNING: Ensure that the lock prevents the switch from being turned on.

How to Use the Cutterhead Lock

The cutterhead lock PC4 Figure 13 helps to eliminate snipe in the board that is being planed. Snipe can also be eliminated by butting boards end to end and feeding them through the planer. Long boards should ALWAYS be supported, when feeding them through the planer to help eliminate snipe.
OPERATION

NOTE: To lock the cutterhead, turn handle clockwise.
To unlock, turn handle counterclockwise.

How to Adjust the Head Assembly

The head assembly contains the cutterhead, feed rollers, chip deflector and motor. Raising and lowering the head assembly controls the depth of cut.

To adjust the head assembly, unlock the cutterhead lock handle PC4 Figure 13. Turn the cutterhead height adjusting handle clockwise to raise or counter-clockwise to lower the cutterhead. One revolution of handle PC3 Figure 14 will move the cutterhead up or down 1/16 inch (1.6mm).

How to Use the Material Removal Gauge

See Figure 15
OPERATION

Your planer is equipped with a material removal gauge A . It is used to indicate the amount of wood that will be removed in one pass with the carriage set at its current height. The material removal gauge reads across the entire width of the planer head.

Slide approximately 3 inches of the workpiece B under the carriage.
Be sure that the workpiece is lying flat against the table of the planer. If the workpiece is inserted at an angle, the reading may be inaccurate.
Lower the carriage on the workpiece until the material removal bar engages the wood. You will see the red arrow A moving up the scale to indicate the amount to be removed with the carriage at that height.
Adjust the carriage height until the desired depth of cut appears on the gauge.
Note this depth as you may have to back the cutterhead off the board to allow you to remove it. Once this is done. Pull the material out from under the carriage and reset the cutterhead to the desired depth.
Turn the unit on and feed your material into the cutter head.

NOTE: DO NOT exceed the recommended depth of cut for various widths of material, shown in the “RECOMMENDED DEPTH OF CUT” section below.

WARNING: DO NOT turn the unit “ON” with the workpiece in position.

RECOMMENDED DEPTH OF CUT

NOTE: One revolution of the cutterhead height adjusting handle will move the cutterhead up or down 1/16 inch (1.6mm).

You can make a 1/8 inch (3.2mm) depth-of-cut in soft woods up to 6 inch (152mm) wide and in hard woods up to 4 inch (102mm) wide. (Figure 16)
OPERATION

For 6 inch (152mm) through 13 inch (330mm) wide soft wood, use a maximum depth-of-cut of 1/16 inch (1.6mm). For 6 inch (152mm) through 13 inch (330mm) wide hard wood, use a maximum depth-of-cut of 3/64 inch (1.2mm) (Figure 16).

IMPORTANT: A shallow depth-of-cut will produce a better finish.

How to Use the Depth Stop

Your planer is equipped with a depth stop dial F6 as shown in Figure 17 for repetitive planing. Any thickness between 1/8 inch and 1 1/4 inch can be selected using the scale on the depth stop. Detents are provided at 1/8 inch, 1/4 inch, 1/2 inch, 3/4 inch, 1 inch, and 1 1/4 inch.
OPERATION

To set the minimum depth to which the cutterhead can travel with the depth stop:

Check to see that the cutterhead is set above 1 1/4 inch before trying to set the depth stop.
Make sure dial F7 is unlocked by rotating the locking knob B counterclockwise.
Turn the dial F7 to the desired thickness setting so that it aligns with the indicator line A as shown in Figure 17.
Lock the gauge in place by turning the locking knob B clockwise, as shown in Figure 17.
Plane the workpiece at desired increments until the correct final thickness is achieved.

NOTE: DO NOT use force to lower the carriage below the level that the depth stop indicates. This will result in permanent damage to the height adjustment system on your planer.

How to Use the Adjustable Indexing Ring

The cutterhead height adjusting handle has an adjustment ring A Figure 18. The Adjustable Index Ring is best utilized after the initial cut has been made. To use the adjustment ring to make fine adjustments:
OPERATION

Once the initial cut has been made and fine tuning is required, measure the thickness of a planed board.
Set the ring A Figure 18 to align the zero with the arrow B.
Rotate the handle to the desired depth of cut, as indicated on the ring. Each indicator on the ring is equivalent to 1/128 inch (.2mm) for making minute cuts.
Plane the workpiece and then repeat this process until you approach the final desired thickness.

OPERATION

Follow these few steps to achieve the best results.

True One Face – Feed one face of the board over a jointer, making thin cuts with each pass, until the entire surface is flat.
Plane to Thickness – Place the side you just surfaced in STEP 1 face down and feed the board through the planer, plane until this side is flat. Then plane both sides of the board until you are satisfied with the thickness, making thin cuts, alternating sides with each pass. If, during the planing operation, you notice the board twisting, warping or bowing, repeat STEP 1 and true one face.
When planing long stock, provide additional support to the in-feed and out feed end of the workpiece.
ALWAYS engage the cutterhead lock before planing. Plane with the grain ONLY, and keep table clean. Occasionally, wax the table surface to reduce friction.
Cross-cut the workpiece to its final length.

NOTE: Feed the wood through the planer at different places on the table to help eliminate uneven wear of the knives.

Proper Planing Techniques

Lower the carriage to the desired height for your first pass.
Turn the unit on and feed the material into the feed rollers.
Examine the finished cut and adjust the carriage to the appropriate height for your next pass.
Feed workpieces through alternating areas of the planer for even blade wear – not just through the center of the machine. One way to do this is to start with the workpiece on the left for the first pass, in the middle on the next and on the right side for third pass – and then repeat.

NOTE: Flip the board over between each pass.

WARNING: DO NOT turn the unit on with the workpiece inserted under cutterhead. Wait until the roller and cutterhead are up to full speed before feeding your material into the machine.

For best results, plane both sides of the workpiece to reach desired thickness. For example, if you need to remove 1/8 inch from your workpiece, remove 1/16 inch from each side. This not only allows the workpiece to dry with an even moisture content, it also produces finer cuts.

WARNING: Plane ONLY wood that is free from foreign objects, with no loose knots and as few tight knots as possible. DO NOT plane wood that is severely warped, twisted, knotted or bowed.

WARNING: DO NOT place your body between the rear of the planer and a stationary object while material is feeding. Serious injury could result.

Minimum/Maximum Width/Height/Depth

NOTE: ALWAYS plane in the direction of the grain. Support the workpiece adequately at all times. Planing material less than 3/4 inch wide is not recommended. If you must plane narrow material, group several pieces together and plane them as one wide workpiece whenever possible. The maximum depth of cut your planer can take in one pass is 1/8 inch (on material less than 6 inch wide). NEVER attempt to modify your planer to take a deeper cut. Follow the recommended depth/width of cut guidelines shown in Figure 16 for best results.

Snipe
Snipe is a depression made when an unsupported end of your material drops toward the floor, causing the opposite end to lift up into the cutter head.

To Avoid Snipe
Feed the workpiece into the planer so it is level and remains flat against the table at all times.
Keep the workpiece level throughout planing operation by receiving or “catching” it from the rear of the planer. If you are planing material that is especially long, the use of additional material support is recommended.

Twisted, Cupped and Bowed Wood
If both sides of your material are very rough or if the material is cupped, bowed or twisted, your planer may not produce the desired result.
Ideally, you should have at least one flat surface/face on your material before you plane. Your thickness planer will work best with material that has been run through a jointer to produce one flat surface. If you DO NOT have at least one flat surface or a jointer, see the following recommendations.

To Plane Twisted Wood
WARNING: Twisted wood may jam your planer. If a jam occurs, turn the power “OFF”, disconnect the power supply and raise the cutterhead to release the workpiece from the cutter.

If your material is ONLY slightly twisted, plane both sides alternating from one to the other until the desired thickness is reached.

To Plane Cupped Wood
To obtain the best possible results with cupped wood, rip the material down the middle and plane it as two separate pieces. Ripping the material reduces the severity of the cup and allows the machine to deliver better results. Understand that you will have to remove more material on cupped wood to achieve the desired thickness than you would on a normal board. If ripping the material is not an option, plane one side of the material until flat, then plane the opposite side until it is also flat. Start with the cupped portion of the board facing down.

NOTE: DO NOT flip the board back and forth between each pass as recommended by the general planing directions.

To Plane Bowed Wood
The feed rollers and cutter head in your planer will push the bow out of the material as it feeds. However, when the material exits the planer, the pressure of the rollers and cutterhead will release allowing the wood to spring back into a bowed formation. To properly remove the bow, use a jointer.

MAINTENANCE/ADJUSTMENT

WARNING: To reduce the risk of injury, turn unit off and disconnect the machine from power source before installing and removing accessories, before adjusting or when making repairs. An accidental start-up can cause injury.

WARNING: Wear gloves when you remove the knives for sharpening or replacement. The knives in this planer are very sharp.

WARNING: Disconnect the machine from the power source.

WARNING: The knives are sharp. Be careful when removing, handling, or installing knives.

HOW TO CHECK, ADJUST, CLEAN AND REPLACE KNIVES

The knives supplied with your planer are double edged and reversible so that you can turn the knives end-for-end when one edge becomes dull or chipped. To change the knives see Figures 19 – 22.
MAINTENANCE/ADJUSTMENT

Raise the cuter head assembly to 4 inch (102mm) on the “Scale and Pointer”.
Remove the screws A . Pull the dust deflector or dust collection attatchment – whichever is installed – B straight out.
Insert the supplied wrench PC5 into the hex hole. Rotate the cutterhead until the cutterhead lock engages.
Remove the seven screws E and use magnetic end of the wrench to remove the hold-down bar F .
Place the magnetized end of the wrench PC5 at the center of the knife. Lift the wrench until the knife H separates from the pins. Remove the knife.
Repeat steps 3 through 5 to remove the other two knives. Press down the cutterhead lock release and usethe supplied wrench PC5 to rotate the cutterhead until the lock engages and the next knife is in position to be removed.
IMPORTANT: After removing all knives fromcutterhead, carefully set them aside. Using a cloth rag and isopropyl alcohol, clean the cutterhead, knives and hold-down bars free of gum, tar and pitch residue. Take special care to clean the cutterhead under the knife area and the cutterhead radius in front of the knife area.
Doing this will increase the life of your planer.
Take this time also to clean the rollers I Figure 23.
Your unit is equipped with double-edged knives. If the second edge of the knife has not been used, rotate the knife 180 degrees and replace on the cutterhead.
Replace the knives if both sides have been used.
Attach the hold-down bar F Figure 21 that you removed in S TEP 4. Tighten all fasteners securely.
Depress the cutterhead lock release and rotate the cutterhead to the next empty position until the cutterhead lock engages.
Repeat steps 9 through 11 to replace the other knives.
Reattach the dust deflector or dust collection port.

How to Adjust the In-Feed and Out-Feed Tables

Your unit has been factory set to eliminate snipe. If your unit loses its adjustment and causes snipe, you can adjust the in-feed and outfeed tables to minimize this condition.

Raise the cutter head.
Place a dime A Figure 24 at each end of the Wear Table (in-feed and out-feed).
Place a straight edge B across the two dimes. Extend the straight edge past the edges of the in-feed and outfeed tables.
If your tables are properly adjusted, the straight edge will touch both of the dimes and both the edges of the tables.
If your table needs adjustment, loosen the lock nuts D Figure 25 on the table height-adjustment screws C .

Adjust the screws up or down to achieve the desired table height.
Make sure that both height-adjustment screws contact the bottom of the table after adjustment.
Re-tighten lock nuts.

How to Calibrate the Depth Adjustment Scale

The depth adjustment scale A Figure 26 on your planer is set at the factory. However, with extended use, the depth adjustment scale could show an incorrect measurement. To check the depth adjustment scale, plane a piece of scrap wood, noting the measurement on the depth adjustment scale. Measure the finished thickness of the workpiece. When measuring the thickness, measure away from the ends. Beware of snipe. Measuring the snipe could result in inaccurate measurements. If the thickness of the workpiece does not match the reading on the depth adjustment scale, loosen the two screws B on the red indicator. Adjust the pointer up or down until its reading matches the finished thickness of the workpiece. Securely retighten the screws.
MAINTENANCE/ADJUSTMENT

Wear Table and In-Feed/ Out-Feed Table Maintenance

Keep the table clean and free from oil, grease, and pitch. Treat the table with paste wax to help maintain its smooth finish.

Circuit Breaker Reset Button

Your planer is equipped with an 18 amp circuit breaker. If your planer becomes overloaded and stops operating, turn off the planer, let the unit sit for 2 minutes and press the reset button F10 as shown in Figure 27 before you resume working.
MAINTENANCE/ADJUSTMENT

WARNING: To prevent the planer from starting unexpectedly if power is interrupted by a circuit breaker trip, make sure the switch is in the “OFF” position before restoring power.

NOTE: Circuit breaker overload is often the result of dull knives.
Change your knives on a regular basis to avoid tripping your breaker. Check your knives before re-setting the circuit breaker and continuing to plane.

Brush Change
Your planer is equipped with brush caps C Figure 28 that are external to the motor. If your brushes need to be replaced, begin by acquiring a new set from a RIDGID® service center or a dealer authorized to service RIDGID® products. Use ONLY identical RIDGID® brushes.
MAINTENANCE/ADJUSTMENT

Replacing the Drive Belt

Drive belts are available at extra cost at RIDGID® authorized service centers. Replacement of the drive belt should be performed by qualified service personnel.

Keep Machine Clean
Periodically blow out all air passages with dry compressed air. All plastic parts should be cleaned with a soft damp cloth.
NEVER use solvents to clean plastic parts. They could possibly dissolve or otherwise damage the material.

WARNING: Wear certified safety equipment for eye, hearing and respiratory protection while using compressed air.

Lubrication

Apply household floor paste wax to the machine table, extension table or other work surface weekly. Or use a commercially available protective product designed for this purpose. Follow the manufacturer’s instructions for use and safety.
