Safety
! WARNING “READ ALL INSTRUCTIONS” — Failure to follow the SAFETY RULES identified by BULLET (●) symbol listed BELOW and other safety precautions, may result in serious person-
al injury.
General Safety Rules
For Bench Top Tools
Work Area
●Keep work area clean and well lit. Cluttered benches and dark areas invite accidents.
●Do not operate power tools in explosive atmospheres, such as in the presence of flammable liquids, gases or dust. Power tools create sparks which may ignite the dust or fumes.
●Keep bystanders, children and visitors away while operating a power tool. Distractions can cause you to lose control.
●Store idle tools out of reach of children and other untrained persons. Tools are dangerous in the hands of untrained users.
●Do not leave tool running unattended, turn power off. Do not leave tool until it comes to a complete stop.
●MAKE WORKSHOP CHILDPROOF with pad lock, master switches, or by removing starter keys.
Electrical Safety
●Before plugging in the tool, be certain the outlet voltage supplied is compatible with the voltage marked on the nameplate within 10%. An outlet voltage incompatible with that specified on the nameplate can result in serious hazards and damage to the tool.
●Double insulated tools are equipped with 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 a polarized outlet. Do not change the plug in any way. Double insulation eliminates the need for the three wire grounded power cord and grounded power supply.
●Avoid body contact with grounded surfaces such as pipes, radiators, ranges and refrigerators. There is an increased risk of electric shock if your body is grounded.
●Do not expose power tools to rain or wet conditions. Water entering a power tool will increase the risk of electric shock.
●Do not abuse the cord. Never use the cord to carry the tools or pull the plug from an outlet. Keep cord away from heat, oil, sharp edges or moving parts. Replace damaged cords immediately. Damaged cords increase the risk of electric shock.
●When operating a power tool outside, use an outdoor extension cord marked “W-A” or “W”. These cords are rated for outdoor use and reduce the risk of electric shock.
Personal Safety
●Stay alert, watch what you are doing and use common sense when operating a power tool. A moment of inattention or use of drugs, alcohol or medication while operating power tools can be dangerous.
●Dress properly. Do not wear loose clothing or jewelry. Contain long hair. Keep your hair, clothing and gloves away from moving parts. Loose clothes, jewelry or long hair can be caught in moving parts. Roll long sleeves above elbows. Rubber gloves and non-skid footwear are recommended when working outdoors.
●Avoid accidental starting. Be sure switch is “OFF” before plugging in. Carrying tools with your finger on the switch or plugging in tools that have the switch “ON” invites accidents.
●Remove adjusting keys or wrenches before turning the tool “ON”. A wrench or a key that is left attached to a rotating part of the tool will be thrown.
●Do not overreach, keep proper footing and balance at all times. Proper footing and balance enables better control of the tool in unexpected situations.
●Do not stand on tool or its stand. Serious injury may occur if the tool is tipped or if the cutting tool is accidentally contacted. Do not store materials on or near the tool such that it is necessary to stand on the tool or its stand to reach them.

Safety
! WARNING “READ ALL INSTRUCTIONS” — Failure to follow the SAFETY RULES identified by BULLET (●) symbol listed BELOW and other safety precautions, may result in serious person-
al injury.
●Use safety equipment. Always wear safety goggles. Dust mask, safety shoes, hard hat or hearing protection must be used for appropriate conditions. Everyday eyeglasses only have impact resistant lenses, they are NOT safety glasses.
Tool Use and Care
●Use clamps or other practical way to secure and support the workpiece to a stable platform. Holding the work by hand or against your body is unstable. It allows for work to shift, causes binding of the tool and loss of control.
●Do not force tool. Use the correct tool for your application. The correct tool will do the job better and safer at the rate for which it is designed. Do not use the tool for purpose not intended - for example; do not use the miter saw for slicing meats.
●Do not use tool if switch does not turn it “ON” or “OFF”. Any tool that cannot be controlled with the switch is dangerous.
●Disconnect the plug from the power source before making any adjustments or changing accessories. Such preventive safety measures reduce the risk of starting the tool accidentally.
●Keep cutting tools sharp and clean. Properly maintained tools, with sharp cutting edges, are less likely to bind and easier to control. When mounting saw blades be certain that the arrow on the blade matches the direction of the arrow marked on the tool and that the teeth are also pointing in the same direction.
●Inspect guards before using a tool. Keep guards in place. Check moving parts for binding or any other condition that may affect the normal operation or safety features of the tool. If damaged, have tool serviced before using the tool. Many accidents are caused by poorly maintained tools.
●Do not alter or misuse tool. Any alteration or modification is a misuse and may result in serious personal injury.
●The use of any other accessories not specified in this manual may create a hazard.
Accessories that may be suitable for one type of tool, may become hazardous when used on an inappropriate tool.
Service
●Tool service must be performed only by qualified repair personnel. Service or maintenance performed by unqualified personnel may result in misplacing internal wires and components which could cause serious hazard.
●When servicing a tool, use only identical replacement parts. Follow instructions in the Maintenance section of this manual. Use of unauthorized parts or failure to follow Maintenance Instructions may create a hazard.
Safety Rules
For Miter Saws
●Use clamps to support workpiece whenever possible. If supporting the workpiece by hand, you must always keep hand outside of “No Hand” area as marked with a symbol on the base. Do not use this saw to cut pieces that are too small to be securely clamped.
Your hand if placed inside the “No Hands” region can easily slip or be pulled into the blade.
●Do not reach in back of the saw blade behind the fence with either hand to hold down or support the workpiece, remove wood scraps, or for any other reason. The proximity of the spinning saw blade to your hand may not be obvious and you may be seriously injured.
●Never cross your hand over intended line of cutting. Supporting the workpiece “cross handed” i.e. holding the left side of the workpiece with your right hand is very dangerous.
●Always disconnect the power cord from the power source before making any adjustments or attaching any accessories. You may unintentionally start the saw, leading to serious personal injury.
●Miter saws are intended to cut wood or woodlike products, they cannot be used with abrasive cutoff wheels for cutting ferrous material such as bars, rods, studs, etc. However, if cutting materials like aluminum or other non-ferrous metals, use only saw blades specifically recommended for nonferrous metal cutting. Cutting ferrous materials causes excessive sparking and will damage the lower guard and will overload the motor. (NOTE: S-B Power Tool Company does not offer 12” metal cutting blades.)

Safety
! WARNING “READ ALL INSTRUCTIONS” — Failure to follow the SAFETY RULES identified by BULLET (●) symbol listed BELOW and other safety precautions, may result in serious person-
al injury.
●Inspect your workpiece before cutting. If workpiece is bowed or warped, clamp it with the outside bowed face toward the fence. Always make certain that there is no gap between the workpiece, fence and table along the line of the cut. Bent or warped workpieces can twist or rock and may cause binding on the spinning saw blade while cutting. Also, make sure there are no nails or foreign objects in the workpiece.
●Do not use the saw until the table is clear of all tools, wood scraps, etc., except the workpiece. Small debris or loose pieces of wood or other objects that contact the revolving blade can be thrown with high speed at the operator.
●Do not feed workpiece into the blade or cut “freehand” in any way. Workpiece must be stationary and clamped or braced by your hand. Saw must be fed through the workpiece smoothly and at a rate which will not overload the saw’s motor.
●Cut only one workpiece at a time. Multiple workpieces cannot be adequately clamped or braced and may bind on the blade or shift during cutting.
●Be certain the miter saw is mounted or placed on a level, firm work surface before using. A level and firm work surface reduces the risk of the miter saw becoming unstable.
●Plan your work. Provide adequate support accessories such as tables, saw horses, table extension, etc. for workpieces wider or longer than the table top (see page 20). Workpieces longer or wider than the miter saw table can tip if not securely supported. If the cutoff piece or workpiece tips it can lift the lower guard or be thrown by the spinning blade.
●Do not use another person as a substitute for a table extension or as additional support. Unstable support for the workpiece can cause the blade to bind or the workpiece to shift during the cutting operation pulling you and the helper into the spinning blade.
●The cutoff piece must not be jammed against or pressured by any other means against the spinning saw blade. If confined, i.e. using length stops, it could get wedged against the blade and thrown violently.
●Always use a clamp or a fixture designed to properly support round material such as dowel rods, or tubing. Rods have a tendency to roll while being cut, causing the blade to “bite” and pull the work with your hand into the blade.
●When cutting irregularly shaped work-
pieces, plan your work so it will not slip and pinch the blade and be torn from your hand.
A piece of molding, for example, must lie flat or be held by a fixture or jig that will not let it twist, rock or slip while being cut.
●Let the blade reach full speed before contacting the workpiece. This will help avoid thrown workpieces.
●If the workpiece or blade becomes jammed or bogged down, turn miter saw “OFF” by releasing switch. Wait for all moving parts to stop and unplug the miter saw, then work to free the jammed material. Continued sawing with jammed workpiece could cause loss of control or damage to miter saw.
●Braking action of the saw causes the saw head to jerk downward. Be ready for this reaction when making an incomplete cut or when releasing the switch before the head is completely in the down position.
●After finishing the cut, release the switch, hold the saw arm down and wait for blade to stop before removing work or cutoff piece. If blade does not stop within five (5) seconds, unplug the saw and follow the instructions in the Troubleshooting section.
REACHING WITH YOUR HAND UNDER A COASTING BLADE IS DANGEROUS!
●There are additional safety instructions for particular operations of the saw in the operating section. Read the rest of the manual for safe operation.
●For slide action cutting, first PULL saw head assembly away from the fence, until blade clears the workpiece or to its maximum extension if blade cannot clear the workpiece. Make certain the clamp does not interfere with the guard and head assembly. Second, turn saw “ON” and lower the saw to the table. Then PUSH saw through the workpiece. Release the switch and wait for the blade to completely stop before raising the head assembly and removing the workpiece.
Never “pullcut” since blade may climb the workpiece causing KICKBACK.
●For chop action cutting, slide the head assembly to the rear as far as it will go and tighten slide lock knob. Then turn the saw “ON” and lower the head assembly to make the cut. Release the switch and wait for the blade to completely stop before raising the head assembly and removing the workpiece.
Failure to tighten the slide lock knob can cause the blade to suddenly climb up on the top of the workpiece and force itself toward you.

Double Insulated Tools |
Extension Cords |
Double insulation is a design concept used in electric power tools which eliminates the need for the three wire grounded power cord and grounded power supply system. It is a recognized and approved system by Underwriter’s Laboratories, CSA and Federal OSHA authorities.
●Servicing of a tool with double insulation requires care and knowledge of the system and should be performed only by a qualified service technician.
●Replace damaged cords immediately. Use of damaged cords can shock, burn or electrocute.
●If an extension cord is necessary, a cord with adequate size conductors should be used to prevent excessive voltage drop, loss of power or overheating. The table shows the correct size to use, depending on cord length and nameplate amperage rating of tool. If in doubt, use the next heavier gauge. Always use U.L. and CSA listed extension cords.
●WHEN SERVICING, USE ONLY IDENTICAL REPLACEMENT PARTS.
●POLARIZED PLUGS. Your tool is equipped with 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. To reduce the risk of electrical shock, do not change the plug in any way.

Electrical Requirements
1.Connect this saw to a 120V, 15-amp branch circuit with a 15-amp time delay fuse or circuit breaker. Using the wrong size fuse can damage the motor.
2.Fuses may “blow” or circuit breakers may trip frequently if motor is overloaded. Overloading can occur if you feed the blade into the workpiece too rapidly or start and stop too often in a short time.
3.Most motor troubles may be traced to loose or incorrect connections, overload, low voltage (such as small size wire in the supply circuit or too overly long supply circuit wire). Always check the connections, the load and the supply circuit whenever motor does not work well.
Electric Brake
Your saw is equipped with an automatic electric brake which is designed to stop the blade from spinning in about five (5) seconds after you release the trigger switch. It is useful when making certain cuts in wood where a coasting blade would result in a wide, imprecise cut.
! WARNING |
When electrical power is lost due to |
blown fuse or other causes, the |
motor will gradually slow down and the braking action is initiated ONLY by the release of the trigger switch.
The electric blade brake of your miter saw has been designed for highest degree of reliability, but unexpected circumstances such as contamination on the commutator and brushes or failure of motor’s components can cause the brake not to activate. If this condition occurs, turn the saw “ON” and “OFF” four to five times without contacting the workpiece. If the tool operates but the brake does not consistently stop the blade in about five (5) seconds, DO NOT use saw and have it serviced immediately.
The brake action of this saw is not intended as a safety feature.
Remember to let the saw blade come to a complete stop before raising the blade from the workpiece. As always the guard system is your best protection against unintentional contact with a spinning saw blade. NEVER wedge open or defeat the closing action of the lower guard.

2.Position dust chute/bag so that it does not interfere with the tool during the cutting operation for all
miter/bevel settings. Make sure dust bag does not interfere with the slide rails during slide cutting.
3.The dust bag requires emptying when full of sawdust. Empty it frequently and after completion of sawing. Carefully remove dust bag from dust
elbow. Empty dust bag in proper trash bin by unzipping the bag. Be extremely careful of dust disposed, materials in fine particle form may be explosive. Do not throw sawdust on an open fire. Spontaneous combustion, may in time, result from mixture of oil or water with dust particles.
Note: The dust port also accepts a standard 1-1/4" vacuum tube for dust collection.
When sawing chemically pressure treated lumber, paint that may be lead based, or any other materials that may contain
carcinogens, use special precautions. A suitable respirator must be worn by all personnel entering the work area. Work area should be sealed by plastic sheeting and persons not protected should be kept out until work area is thoroughly cleaned.

Transporting, Placement and Mounting
! WARNING |
To avoid injury always observe the |
|
following: |
||
|
—Unplug electric cord. Before transporting the saw, rotate head and lock assembly to 60° right miter, lock into detent, slide head assembly to the middle of it’s rail, tighten the slide rail lock knob and lock the head assembly in the lowered position.
Lifting Saw
—To avoid back injury, hold the tool close to your body when lifting. Bend your knees so you can lift with your legs, not your back.
—Lift by using the cast-in carry handles at each side of the bottom of the base.
—Alternate lifting method: When picking tool up from ground, use rear carrying handle and front carrying handle (above guard).
—Never carry the tool by the slide rails, this may cause blade damage.
—Never lift tool by holding switch handle. This may cause serious damage.
—Never carry the miter saw by the power cord or the operational handle. Attempting to lift or carry the tool by the power cord will damage the insulation and the wire connections resulting in electric shock or fire.
—Observe the position of the saw. People standing behind it could be injured by thrown debris.
—Place the saw on a firm, level surface where there is plenty of room for handling and properly supporting the workpiece.
—Bolt, nail or clamp the saw to its support.
Be careful not to over-drive nail or over-torque the bolt. This could
crack foot or damage base.
Mounting Applications
Workbench
Mount the saw using either the four bolt holes (5/16") or the four nail holes to the workbench (Figure 14). Check for clearance to the left and right of the saw.

Basic Saw Operations
Body and Hand Position
Position your body and hands prop- ! WARNING erly to make cutting easier and
safer. Observe the following instructions (Figure 17).
Correct |
Incorrect Use |
Projected Line Of Cut |
Figure 17. Hand Positions
●Never place hands near cutting area. Keep hands and arms outside the “No Hands” zone.
●The “No Hands Zone” is defined as the entire Table plus the fixed portion of the Base on the right and left side of the Table and portions of the Fence within this boundry. This zone is labeled by “No Hands” symbols placed on the fixed Base.
●Be aware of the path of the sawblade. Make a dry run with the saw OFF by conducting a simulated cutting cycle, and observe the projected path of the sawblade. Keep hands out of the path of sawblade.
DRY RUN—It is important to know where the blade will intersect with the workpiece during cutting operations. Always perform the simulated cutting sequence with the power tool switched OFF to gain an understanding of the projected path of the sawblade. Mentally note where the path of sawblade will fall and set up your work to keep your hands and arms out of the path of the spinning blade. Adjust your clamps and fences so that the smooth lower guard and cutting action is not interfered with during cutting operation.
●Hold workpiece firmly against table and fence to prevent movement.
●Keep hands in position until trigger has been released and blade has stopped completely.
●Never place hands on slide rails.
●Keep feet firmly on the floor and maintain proper balance.
●Follow the miter arm when mitering left or right. Stand slightly to the side of the saw blade.
The lower guard may not automatically open under certain cutting conditions. For example, when trying to cut work-
pieces that are near the maximum cutting height capacity. Under these conditions, the workpiece can stop the lower guard movement before the downward motion of the arm could pre-open the lower guard.
If this occurs:
● Workpiece must be securely clamped. This frees a hand to raise the guard by the lip just enough to clear the workpiece (Figure 18).
●Start the saw and begin your cut.
●Once you have cleared the position where the lower guard may bind, release the guard and it will continue to operate automatically as you cut.

Workpiece Support
Long workpieces have a tendency to tip over unless clamped down and
properly supported from underneath.
Clamps
Quick-Action Clamp - This clamp easily secures a workpiece in either of two (2) clamp holes behind the fence (Figure 19).
— Minimum of 1/2" of knurl must engage clamp post to be effective.
— Adjust screw if necessary to clear fence or for large differences in wood heights.
— With clamp in open (lever raised) position, insert clamp into clamp post until rubber foot comes into contact with material.
— Press down on lever to tighten clamp.
— Move the head assembly to check clearance with clamp.
— Pull up on lever to release clamp.
There may be extreme compound cuts where clamp cannot be used.
Support workpiece with hand outside No Hands Zone. Do not try to cut short pieces that cannot be clamped and cause your hand to be in the No Hands Zone.
Long workpiece support
Sliding Base Extensions – These extensions provide extra workpiece support and are especially useful when cutting long workpieces. To reposition the extensions, simply unlock the Base Extension Clamping Levers, reposition the extensions, and relock the levers (Figure 20). (See also Length Stop on page 27.)
Extra-Long Base Extension Rods – The optional MS1222 Base Extension Kit allow the 4412’s base extensions to extend out to 60”. Even after these longer rods are installed on the 4412, the base extensions can be fully retracted for transportation and storage.

Basic Saw Operations
Auxiliary Fence
Certain types of molding need a fence face extension because of the size and position of the workpiece. Holes are provided in the fence to attach an auxiliary fence. The auxiliary fence is used with the saw in the 0° bevel position only.
1. Place a piece of wood against the miter saw fence (Figure 22). (Wood can have a maximum height of 4-1/2". Check that auxiliary fence assembly does not interfere with head assembly.
For splinter-free cuts of molding, attach a one piece wood auxiliary fence and then cut openings with miter saw.
2.Mark the locations of the support holes on the wood from the back side of the fence.
3.Drill and countersink the holes on the front of the support board.
4.Attach (each) auxiliary fence using two (2) 3/16" flat head machine screws. With 3/4" auxiliary fence use 1-1/2" long screws. Secure behind metal fence with washer and machine nuts.
Alternate: With 3/4" auxiliary fence, use 1/4" round head screws wood screws (3/4" long). Drill four (4) smaller (then 1/4" pilot holes through auxiliary fence and run screws through rear of metal fence.
5.Make a full depth cut to create the blade slot. Check for interference between the auxiliary fence
and the lower blade guard. Make adjustments as necessary.

Saw Operations
Miter Cut
—A “miter cut” is a cross-cut made with the blade vertical (non-tilted) at a horizontal angle relative to the fence.
—A miter cut is made at 0° bevel and any miter angle in the range from 52° left to 60° right.
—The miter scale shows the angle of the blade relative to the fence angle is cast-in on the table for easy reading.
—Positive detents have been provided for fast and
accurate mitering at 0°, 15°, 22.5°, 31.6° and 45° left and right and 60° right.
—The crown molding detents (left and right) are at 31.6° (See Cutting Crown Molding for more information page 29).
—For precision settings at angles next to the detents, use the detent override to lock out the detent. This prevents the wedge on the detent lever from slipping back into the detent.
—A miter cut can be made as either a chop cut or a slide cut, depending on the width of the workpiece.
—The kerf inserts should be as close to the blade as possible without touching the blade (see Kerf Inserts for adjustment procedures).
Follow these instructions for making your miter cut:
1.Loosen miter lock knob. Lift miter detent lever and move the saw to the desired angle, using either the detents or the miter scale. Tighten miter lock knob (Figure 28).
2.Extend the base extensions and fence on the side on which the cut will be made. (See Sliding Fence and Base Extension on page 22).
3.Properly position workpiece. Make sure workpiece is clamped firmly against the table or the fence.
Use clamping position that does not ! WARNING interfere with operation. Before
switching on, lower head assembly to make sure clamp clears guard and head assembly.
4.Follow procedures for either chop cut or slide cut (see page 23).
5.Wait until blade comes to a complete stop before returning head assembly to the raised position and/or removing workpiece.

Compound Cuts
—A “compound cut” is a cross-cut made with the blade both at a horizontal angle relative to the fence (at a miter angle) and tilted away from the vertical position (at a bevel angle).
—A compound cut can be made as either a chop cut or a slide cut depending on the width of the workpiece.
—Because it may take several tries to obtain the desired compound angle, perform test cuts on scrap material before making your cut.
Follow these instructions for making your compound cut:
1.Extend the base extensions and fences on the side on which the cut will be made. (See Sliding Fences and Base Extensions on page 22.)
2.Properly position workpiece. Make sure workpiece is clamped firmly against the table or the fence.
! WARNING |
Use clamping position that does not |
|
interfere with operation. Before |
||
|
switching on, lower head assembly to make sure clamp clears guard and head assembly.
3.Set miter and bevel angles according to the instructions on page 24 and 25 for miter and bevel cuts.
4.Follow the procedures for either chop cut or slide cut (see page 23).
5.Wait until blade comes to a complete stop before returning head assembly to the raised position and / or removing workpiece.

Length Stop
The unit’s flip up length stop can be used when making repetitive cuts of the same length.
To set the stop, simply unscrew the knob, flip the stop into position and tighten the knob (Figure 34).
1.To set the cut length, unlock the base extension clamping lever, reposition the base extension and length stop, and relock the levers.
2.The maximum length that can be cut using the length stop is approximately 20".
If desired, the length stop and knob can be moved to the left base extension. The optional MS1223 Length Stop Kit can also be installed on the left side to provide stops on either side of the saw.
To increase the length that can be cut using the length stop, replace the tool’s base extension rods with the optional MS1222 Extra-Long Base Rod Kit , which increases the maximum length that can be cut using the length stop to approximately 30” on either side of the tool.

Saw Operations
Crown Molding Angled to Table and Fence
The preferred method for cutting crown molding with this saw is with the molding laying flat on the table.
—The advantage to cutting moldings angled against fence is that no bevel setting is required. Only the miter angle is adjusted.
—The maximum crown molding width that can be cut and angled to table and fence is 6".
—When cutting crown molding in this fashion it is recommended to purchase and use the optional MS 1221 Horizontal Clamp and Crown Molding Stop Accessory.
Follow these instructions for cutting crown molding angled to table and fence.
1.Position the molding so the bottom (decorative part, which is installed against the wall) is against the fence.
2.For 90º corner, set the miter angle using Chart below. Tighten the miter lock knob (Figure 36).
3.Support crown molding against the fence (see “Body and Hand Position” on page 19.)
4.Follow the procedures for chop or slide cut (see page 23).
5.Wait until blade comes to a complete stop before returning head assembly to the raised position and/or removing workpiece.
NOTE: ALWAYS TAKE A TEST CUT USING SCRAP TO CONFIRM CORRECT ANGLES.
