INSPECT TOOL CORDS PERIODICALLY. If damaged, have repaired by a qualified service technician at an authorized service facility. 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. Repair or replace a damaged or worn cord immediately. Stay constantly aware of cord location and keep it well away from the rotating blade.
INSPECT EXTENSION CORDS PERIODICALLY and replace if damaged.
POLARIZED PLUGS. To reduce the risk of electric shock, this tool has a polarized plug (one blade is wider than the other). This plug will fit in a polarized outlet only one way. If the plug does not fit fully in the outlet, reverse the plug. If it still does not fit, contact a qualified electrician to install the proper outlet. Do not change the plug in any way.
KEEP TOOL DRY, CLEAN, AND FREE FROM OIL AND
GREASE. Always use a clean cloth when cleaning. Never use brake fluids, gasoline, petroleum-based products, or any solvents to clean tool.
STAY ALERT AND EXERCISE CONTROL. Watch what you are doing and use common sense. Do not operate tool when you are tired. Do not rush.
DO NOT USE TOOL IF SWITCH DOES NOT TURN IT
ON AND OFF. Have defective switches replaced by an authorized service center.
USE ONLY CORRECT BLADES. Do not use blades with incorrect size holes. Never use blade washers or blade bolts that are defective or incorrect. The maximum blade capacity of the saw is 12 in.
BEFORE MAKING A CUT, BE SURE ALL ADJUST-
MENTS ARE SECURE.
BE SURE BLADE PATH IS FREE OF NAILS. Inspect for and remove all nails from lumber before cutting.
NEVER TOUCH BLADE or other moving parts during use.
NEVER START A TOOL WHEN ANY ROTATING
COMPONENT IS IN CONTACT WITH THE WORKPIECE.

ELECTRICAL
DOUBLE INSULATION
Double insulation is a concept in safety in electric power tools, which eliminates the need for the usual three-wire grounded power cord. All exposed metal parts are isolated from the internal metal motor components with protecting insulation. Double insulated tools do not need to be grounded.
WARNING:
The double insulated system is intended to protect the user from shock resulting from a break in the tool’s internal wiring. Observe all normal safety precautions to avoid electrical shock.
NOTE: Servicing of a product with double insulation requires extreme care and knowledge of the system and should be performed only by a qualified service technician. For service, we suggest you return the tool to your nearest authorized service center for repair. Always use original factory replacement parts when servicing.
ELECTRICAL CONNECTION
This tool has a precision-built electric motor. It should be connected to a
power supply that is 120 volts, 60 Hz, AC
only (normal household current). Do not operate this tool on direct current (DC). A substantial voltage drop will cause a loss of power and the motor will overheat. If the tool does not operate when plugged into an outlet, double-check the power supply.
EXTENSION CORDS
When using a power tool at a considerable distance from a power source, be sure to use an extension cord that has the capacity to handle the current the product will draw. An undersized cord will cause a drop in line voltage, resulting in overheating and loss of power. Use the chart to determine the minimum wire size required in an extension cord. Only round jacketed cords listed by Underwriter’s Laboratories
(UL) should be used.
When working outdoors with a product, use an extension cord that is designed for outside use. This type of cord is designated with “WA” on the cord’s jacket.
Before using any extension cord, inspect it for loose or exposed wires and cut or worn insulation.

The saw base has eight mounting holes: four large bolt holes (B) and four small screw holes (A). If using bolts, they should be of sufficient length to accommodate the saw base, lock washers, hex nuts, and the thickness of the workbench or other mounting surface. Tighten all four bolts or screws securely. Do not use screws if mounting to a leg stand.
The hole pattern for mounting to a workbench is shown in figure 8. Carefully check the workbench after mounting to make sure that no movement can occur during use. If any tipping, sliding, or walking is noted, secure the workbench to the floor before operating.

ASSEMBLY
NOTE: Many of the illustrations in this manual show only portions of the compound miter saw. This is intentional so that we can clearly show points being made in the illustrations.
Never operate the saw without all guards securely in place and in good operating condition.
LOCKING / UNLOCKING THE SAW ARM
See Figure 9.
When locking and unlocking the saw arm, it is not necessary to loosen the depth control knob.
To unlock and raise the saw arm:
Firmly grasp the “D” handle and apply downward pressure while at the same time pulling the depth guide out and away from the saw housing.
Turn the guide to the right until the flat of the guide is facing up.
Release the guide and slowly raise the saw arm.
To relock the saw arm:
Firmly grasp the “D” handle and apply downward pressure while at the same time pulling the depth guide out and away from the saw housing.
Turn the guide to the left until the hole in the guide is positioned over the lock pin.
Release the guide allowing the lock pin to align with the hole in the guide.
Check that the slide lock knob is locked in place by turning the knob clockwise.
USING THE DEPTH GUIDE
See Figure 10.
When used, the depth guide limits the downward travel of the blade when cutting dadoes and other non-through cuts.
Make a mark on the lock pin with a pencil for use with the scale on the guide. “A” on the guide represents the saw blade teeth being level with the miter table. Each mark on the depth guide is approximately 1/4 in. Always make a practice cut on scrap wood. With the flat side of the guide facing up, the saw can be used without any interference from the guide.
To use the depth guide:
If the saw is in storage or transport position, unlock the saw arm.
Position the depth guide by turning until it engages the internal locking mechanism.
Loosen the depth control knob (turn knob counter-
clockwise).
Determine the desired depth of cut, set the guide to that mark, and retighten the depth control knob (turn knob clockwise).
NOTE: To override the depth setting, pull the depth gauge out and away from the saw housing and turn the guide until the flat of the guide is facing up.

INSTALLING THE DUST BAG
See Figure 11.
Squeeze the metal clips on the dust bag, then slide the metal ring over the end of the dust guide. Position the metal ring so it is between the two molded rings on the dust guide. Release the dust bag clips.
Snap the frame onto the slide bar by squeezing the dust bag frame, then pushing it down over the slide bar.
Insert the dust guide inside the exhaust port in the upper blade guard.
Slip the dust bag over the frame with the zipper facing down.
NOTE: For efficient operation, empty the dust bag before it is half full. This will permit better air flow through the bag.
INSTALLING THE WORK CLAMP
See Figure 12.
WARNING:
In some operations, the work clamp assembly may interfere with the operation of the blade guard assembly. Always make sure there is no interference with the blade guard prior to beginning any cutting operation to reduce the risk of serious personal injury.
The work clamp provides greater control by clamping the workpiece to the miter table. It also helps to prevent the workpiece from creeping toward the saw blade. This is very helpful when cutting compound miters. Depending on the cutting operation and the size of the workpiece, it may be necessary to use a C-clamp instead of the work clamp to secure the workpiece prior to making the cut. The work clamp can be installed and used on either side of the blade.
To install the work clamp:
Place the work clamp shaft in one of the holes located behind the sliding miter fence.
NOTE: Align the pin on the work clamp shaft with the slot in the hole.
Rotate the knob on the work clamp to move it up or down as needed.
NOTE: The work clamp has a quick release lever that makes positioning of the work clamp effortless. Push the button on the side of the work clamp to quickly release the workpiece.

ASSEMBLY
DANGER:
Laser radiation. Avoid direct eye contact with light source.
ALIGNING THE LASER GUIDE LINE
See Figure 14.
The laser guide will generate a laser line on the work surface when the saw blade is spinning. The laser line will appear as a broken line on the workpiece when the blade assembly is in the uppermost position and the motor switch is activated.
This broken line will let you see your mark and your laser guide line at the same time, and will assist you in lining up your mark for more accurate cutting of the workpiece.
Align the laser line and your mark with the blade at the uppermost position. Once both lines are in alignment, do not move the workpiece until after you have finished cutting.
As the blade assembly is lowered toward the workpiece, the broken line will become solid.
Follow the directions below for using the laser guide:
Removing the Mark:
Position the laser line on the left edge of your mark on the work surface in order to remove the mark.
To Cut the Mark:
Position the laser line near or over your mark on the work surface in order to cut the mark.
To Leave the Mark:
Position the laser line near the right edge of your mark on the work surface in order to leave the mark.
After you have become familiar with using the laser guide, you will be able to remove, cut, or leave your mark on the work surface. Practice will teach you the correct position for aligning the laser line with your mark. To adjust the position of the laser line, see the Adjustments section of this manual.

WARNING:
Do not allow familiarity with tools to make you careless. Remember that a careless fraction of a second is sufficient to inflict severe injury.
WARNING:
Do not start the compound miter saw without checking for interference between the blade and the miter fence. Damage could result to the blade if it strikes the miter fence during operation of the saw.
WARNING:
Always wear safety goggles or safety glasses with side shields when operating tools. Failure to do so could result in objects being thrown into your eyes resulting in possible serious injury.
CUTTING WITH YOUR SLIDING COMPOUND
MITER SAW
WARNING:
Do not use any attachments or accessories not recommended by the manufacturer of this tool.
The use of attachments or accessories not recommended can result in serious personal injury.
APPLICATIONS
You may use this tool to cut only wood or plastic as listed below:
Cross cutting miters, joints, etc. for picture frames, moldings, door casings, and fine joinery.
Bevel and compound cutting
Cross cutting wide workpieces.
NOTE: The blade provided is fine for most wood cutting operations, but for fine joinery cuts or cutting plastic, use one of the accessory blades available from the RIDGID dealer.
WARNING:
When using a work clamp or C-clamp to secure the workpiece, clamp workpiece on one side of the blade only. The workpiece must remain free on one side of the blade to prevent the blade from binding in workpiece. The workpiece binding the blade will cause motor stalling and kickback. This situation could cause an accident resulting in possible serious personal injury.
WARNING:
To avoid serious personal injury, always tighten the miter lock lever and the bevel lock lever securely before making a cut. Failure to do so could result in movement of the control arm or miter table while making a cut.
WARNING:
Before starting any cutting operation, clamp or bolt the miter saw to a workbench. Never operate the miter saw on the floor or in a crouched position.
Failure to heed this warning can result in serious personal injury.
WARNING:
Do not try to cut narrow pieces using the sliding feature. Failure to heed this warning could result in serious personal injury.
WARNING:
To avoid serious personal injury, keep your hands outside the no hands zone, at least 3 in. from blade.
Never perform any cutting operation freehand (without holding workpiece against the fence). The blade could grab the workpiece if it slips or twists.

OPERATION
TO COMPOUND MITER CUT
See Figure 38.
A compound miter cut is a cut made using a miter angle and a bevel angle at the same time. This type of cut is used to make picture frames, cut molding, make boxes with sloping sides, and for certain roof framing cuts.
To make this type of cut the control arm on the miter table must be rotated to the correct angle and the saw arm must be tilted to the correct bevel angle. Care should always be taken when making compound miter setups due to the interaction of the two angle settings.
Adjustments of miter and bevel settings are interdependent with one another. Each time you adjust the miter setting you change the effect of the bevel setting. Also, each time you adjust the bevel setting you change the effect of the miter setting.
It may take several settings to obtain the desired cut. The first angle setting should be checked after setting the second angle, since adjusting the second angle affects the first.
Once the two correct settings for a particular cut have been obtained, always make a test cut in scrap material before making a finish cut in good material.
NOTE: It may be necessary to adjust or remove the sliding miter fence to insure proper clearance prior to making the cut.
Make sure the slide lock knob is tightened securely.
Raise saw arm to its full height.
Lift the miter lock lever to unlock. Rotate the miter table until the pointer aligns with the desired angle on the miter scale.
NOTE: You can quickly locate 0°, 15°, 22.5°, 31.6°, 45°, and 60° left or right by spinning the miter thumbwheel up.
The lock plate will seat itself in one of the positive stop notches, located in the miter table base.
Push the miter lock lever down to lock the miter table.
Lift the bevel lock lever and move the saw arm to the left or right to the desired bevel angle.
Once the saw arm has been set at the desired angle, securely tighten the bevel lock lever.
Place the workpiece flat on the miter table with one edge securely against the fence. If the board is warped, place the convex side against the fen ce. If the concave edge of a board is placed against the fence, the board could collapse on the blade at the end of the cut, jamming the blade . See Figures 47 - 48.

OPERATION
ROUGH CUTTING A DADO
See Figures 42 - 43.
Using a wood chisel and the depth guide, it is possible to make a rough dado cut. The marks on the depth guide are to be used for reference only. Always make a practice cut on scrap wood.
To make the cut:
Unlock the slide lock knob.
Raise the saw arm to its full height.
Using the marks on the depth guide, set the blade to the correct cutting depth.
With the saw off, pull the saw arm forward. Turn the saw on (let blade reach maximum speed), then push the blade down on top of the workpiece then back toward the rear of the saw to make a cut.
Cut two outside grooves in the workpiece.
Using a wood chisel, remove the material between the two outside grooves.
USING AN AUXILIARY FENCE
See Figure 44.
Certain unusual cuts may benefit from a thicker miter fence
(auxiliary fence) due to the size and position of the workpiece.
The holes provided in the miter fence are there for just this purpose. The miter fence holes are used to secure the auxiliary fence which requires a piece of wood 1/2 in. thick,
4-1/4 in. high, and 23 in. long to make.
NOTE: The auxiliary fence can only be used when the bevel is set at 0˚. When making a bevel cut, the auxiliary fence
MUST be removed.
To attach the auxiliary fence to the saw:
Place the wood against the miter fence and mark the hole location from behind the fence using a pencil.
Drill holes through the wood then countersink the holes on the front of the wood.
Secure the wood to the miter fence using flat head screws.
With the miter table set at 0˚, make a complete cut through the auxiliary fence to create the blade slot.
NOTE: Check for interference between the auxiliary fence and the lower blade guard. Correct any interference before proceeding.

OPERATION
CUTTING CROWN MOLDING
The compound miter saw does an excellent job of cutting crown molding. In general, compound miter saws do a better job of cutting crown molding than any other tool made.
In order to fit properly, crown molding must be compound mitered with extreme accuracy.
The two contact surfaces on a piece of crown molding that fit flat against the ceiling and the wall of a room are at angles that, when added together, equal exactly 90
°
. Most crown molding has a top rear angle (the section that fits flat against the ceiling) of 52
°
and a bottom rear angle (the section that fits flat against the wall) of 38
°
.
LAYING MOLDING FLAT ON THE MITER
TABLE
See Figure 45.
To use this method for accurately cutting crown molding for a 90
°
inside or outside corner, lay the molding with its broad back surface flat on the miter table and against the fence.
When setting the bevel and miter angles for compound miters, remember that the settings are interdependent; changing one angle changes the other angle as well.
Keep in mind that the angles for crown molding are very precise and difficult to set. Since it is very easy for these angles to shift, all settings should first be tested on scrap molding. Also most walls do not have angles of exactly 90
°
; therefore, you will need to fine tune your settings.
When cutting crown molding by this method, the bevel angle should be set at 33.85
° . The miter angle should be set at
31.6
° either right or left, depending on the desired cut for the application. See the chart below for correct angle settings and correct positioning of crown molding on miter table.
The settings in the chart below can be used for cutting All
Standard (U.S.) crown molding with 52
°
and 38
° angles. The crown molding is placed flat on the miter table using the compound features of your miter saw.

MAKING A CROWN MOLDING SUPPORT JIG
See Figure 46.
A crown molding support jig will need to be made when cutting crown molding with no required bevel setting. The support jig holds the crown molding in place during the cutting operation. When using this method, the saw can be quickly adjusted for corners that are not 90
°
square.
NOTE: A separate support jig must be made for different widths.
To make a support jig:
Using a piece of wood 1/2 in. thick, 4-1/4 in. high, and
23 in. long, place the wood on the miter table against the miter fence.
From the back side of the saw, use a pencil to mark the wood through the holes in the miter fences.
Drill holes through the wood then countersink the holes to accept flat head screws.
Attach the wood to the fence using the flat head screws.
Place a piece of crown molding firmly against the miter table and the wood. Mark the height of the molding with a pencil.
Remove the screws and the wood from the miter fence then cut the wood to this width.
Using small nails and glue, attach a piece of wood
(1/2 in. thick x 1-1/2 in. wide x 23-1/2 or 28 in. long) to the top of the wood.
NOTE: Keep nails away from the area around the blade cutting path.
Securely reattach the support jig to the miter fence.
Make a full 45° left miter cut and a 45° right miter cut through the completed support jig.
34
USING A CROWN MOLDING SUPPORT JIG
Place the crown molding upside down on the miter table with the bottom of the molding against the wood fence.
Use the chart on this and the previous page to select the proper miter angle.
Lift the miter lock lever and position the miter table to the desired setting. Push the miter lock lever down to securely tighten the miter table.
Make sure the slide lock knob is tightened securely.
Slowly lower the blade into and through the molding.
Release the switch trigger and allow the saw blade to stop rotating before raising the blade out of workpiece and removing the workpiece from the miter table.
