General Safety Rules for Bench Top Tools

Work Area

Keep work area clean and well lit. Cluttered benches and dark areas invite acdents.

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 cacause you to lose control.

Store idle tools out of reach of children and other untrained persons. Tools are danger-ous in the hands of untrained users.

Do not leave tool running unattended, turn power off. Do not leave tool until it comes to acomplete 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-skidfootwear 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 unex-pected 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.

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 thblade 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

To reduce risk of injury, use saw blade rated 4800/min (RpM) or greater.

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-fer- rous metals, use only saw blades specifically recommended for non ferrous metal cutting.

Cutting ferrous materials causes excessive sparking and will damage the lower guard and will overload the motor.

(NOTE: Robert Bosch Tool Corporation does not offer 10” metal cutting blades.)

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 22). 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.

7:39 AM Page 4

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 man-ual 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.

Do not allow familiarity gained from frequent use of your miter saw to become commonplace. Always remember that a careless fraction of a second is sufficient to inflict severe injury.

Double Insulated Tools

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.

WHEN SERVICING, USE ONLY IDENTICAL REPLACEMENT PARTS.

POLARIZED PLUGS. To reduce the risk of electrical shock, 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.

Extension Cords

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.

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.

 

When electrical power is lost due to

! WARNING

 

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.

Getting To Know Your Miter Saw (See page 8 & 9)

To avoid injury from accidental starting, remove plug from power

source outlet before making any adjustments.

2.power Switch – The power switch used with the “Lock-OFF” button energizes the unit.

3.Main Handle – This handle contains the power switch. Pulling this handle down lowers the blade into the workpiece.

4.Brush Caps – These caps keep the motor brushes in position and provide easy access for inspecting and replacing brushes.

5.lower Blade Guard/lower Guard lip – The lower blade guard helps protect your hands from the spinning blade. It retracts as the blade is lowered. Lip can be used to raise the lower guard when guard becomes jammed on a workpiece.

6.Blade – Use only 10" blades with 5/8" arbor hole.

7.Sliding fence – Supports the workpiece. The fence has a cast in scale to make repetitive cuts easy. The fence also has holes to secure an auxiliary fence if desired.

8.Kerf Inserts – Kerf inserts can be adjusted to different blade widths to minimize workpiece tear-out.

9.Miter Detent Override – Allows detent action to be locked out allowing for micro adjustments to any miter angle.

10.Miter Scale/Miter Angle Indicator – This scale is cast in on the base of the saw. Indicator is fastened to the table.

11.Miter Detents – There are ten (10) miter detent slots for fast and accurate miter cuts of common miter angles.

12.Miter Detent lever – The lever releases the table from the detent.

13.Miter lock Knob – The miter lock knob locks the miter saw table at any desired miter angle.

14.Table – Sits in base, provides workpiece support, rotates for desired miter cuts and rotates the head assembly. The front extended part of the table is called the miter arm.

15.Base – Provides working surface to support workpiece.

16.Tool Mounting pads – The four corners of the saw provide areas to clamp, bolt or nail the saw to a flat work surface.

Installation And Removal Of The Blade

! WARNING Disconnect plug from power source before performing any as-

sembly, adjustment or repair to avoid possible injury.

1.The miter saw is equipped with a lock pin used to lock the miter saw in the lowered position. To release, push the handle down slightly and pull the lock pin to its full out position and rotate 90°.

NOTE: If there is difficulty in pulling the lock pin out, you may need to adjust the depth stop bolt so the handle can be pushed down.

2.Loosen, but do not remove, both cover plate screws (front and rear). (Figure 1)

3.Lift the lower guard and the cover plate so the blade bolt is exposed (Figure 1).

4.Remove blade bolt by pressing the arbor lock (Item #39 on page 9) while turning bolt clockwise using the (multi purpose tool model 4410) or (multi purpose “L” wrench model 4310).

NOTE: The blade bolt has left hand threading.

5.Remove the blade bolt, outer washer and the blade. Do not remove inner washer (Figure 2).

6.Install 10" blade onto the arbor shaft (Figure 3).

NOTE: Make sure the rotation arrow on the blade matches the clockwise rotation arrow on the lower guard.

! WARNING To avoid injury, do not use a blade larger or smaller than 10"

diameter and 5/8" arbor. Smaller blades will not cut workpiece all the way through and larger blades will cut into table and/or blade guards.

! WARNING

To reduce risk of injury, use saw

 

blade rated 4800/min (RpM) or

greater.

 

7. Replace the outer washer in it’s proper orientation and tighten blade bolt finger tight.

8. Press the arbor lock and tighten blade bolt securely, but do not overtighten.

9. Rotate cover plate to its original position and tighten both cover plate screws.

! WARNING Never use saw without cover plate securely in place. Lower

guard will not function properly.

10.Be sure the arbor lock is released so the blade turns freely.

 

After installing a new blade,

! WARNING

 

make sure the blade does not in-

 

terfere with the table insert at the 0° and 45°

bevel positions. Lower the blade into the table slot and check for any contact with the base or turn table structure. If blade contacts base or table, seek authorized service.

Assembling Dust Elbow And Dust Bag

1.With the miter arm locked in the down position, push the dust elbow onto the dust port. Push the dust bag onto the elbow and rotate both to desired position. (Figure 4).

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 openfire. Spontaneous combustion, may in time, result from mixture of oil or water with dust particles.

NOTE: The dust port accepts the Bosch VAC004 Vacuum Hose Adapter, which allows connection to a Bosch 35mm vacuum hose.

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.

Depth Adjustment

When the diameter of the blade has been reduced due to sharpening, it may be necessary to adjust

the depth stop. When a new blade is installed, it is necessary to check the clearance of the blade to the turn table structure.

Setting Blade Depth for Normal full Cuts

The depth stop adjustment is a feature used when cutting grooves in the workpiece. (See page 30 for cutting grooves.)

1.Loosen and turn both of the lower Jam Nuts to just above the threaded end of the Depth Stop Bolt (Fig. 13).

2.Press Depth Stop Release Button and pull up Depth Stop Bolt until nuts hit the bottom of its support frame.

3.Set the table to the 0° miter position. Push down and slide back saw head to the full back position.

4.While looking at both the blade and the corner where the fence meets the table, turn the Depth Stop Bolt to set the blade depth to about 1/4 inch below the table’s surface.

5.Release the saw head to the up position.

6.Turn both lower Jam Nuts to be tight against the bottom of the support frame. Tighten nuts against each other.

7.Practice slide cutting (with tool unplugged) to verify that the blade does not touch table. If it clears the table, make a practice cut (with tool plugged) on

scrap wood to verify that the cut goes completely through the lower front edge of the workpiece

Do not start the miter saw without ! CAUTION checking for interference between

the blade and the turn table structure. The blade could be ruined if it cuts into the table structure.

Setting Blade Depth for Cutting Grooves

The depth stop can be easily adjusted to limit the cutting depth, such as when creating a rough slot.

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 16). Check for clearance to the left and right of the saw.

1.Each of the four mounting holes should be bolted securely using 5/16" bolts, lock washers, and hex nuts (not included).

2.Locate and mark where the saw is to be mounted.

3.Drill four (4) 5/16" diameter holes through workbench.

4.Place the miter saw on the workbench aligning holes in base with holes drilled in workbench. Install bolts, lock washers and hex nuts. As an alternative, you can mount the saw using drywall screws in the four nail holes.

Supporting surface where saw is to be mounted should be examined carefully after mounting to ensure that no movement can occur during use. If any tipping or walking is noted, secure the workbench or stand before operating the slide compound miter saw.

projected line Of Cut

figure 19. Hand positions

Never place hands near cutting area. Keep hands and arms outside the “No Hands” zone.

Note the "No Hands Zone" sticker located on each side of the base. The "No Hands Zone" is defined as the entire Table plus the portion of the Base on the right and left that falls between the outer edge of these two stickers and portions of the Fence within this boundry.

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 or during the sliding motion of cut, 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 20).

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.

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 24). (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.

Miter Detent Override

The miter detent override feature allows the detent action to be locked out, allowing for micro adjustments at any miter angle. When the desired miter angle is to close to a standard mitering angle that has a detent slot, this feature prevents the wedge on the miter arm from slipping into the detent slot on the base.

1.Lift and hold the miter detent lever (under base arm).

2.Push the detent override clip forward and latch in place over edge. Release miter detent lever (Figure 26).

3.Move miter arm to any position on the miter scale.

4.Lock the miter lock knob to retain miter position.

To Disengage:

5.Loosen miter lock knob and lift the miter detent lever to release the detent override clip. The

clip should automatically disengage and the table should lock into any desired miter detent.

Microfine Miter Adjustment System

This feature allows you to move the turntable by very small increments up to 2 degrees to the left or right of the detent angles (except 60° detent) to reach to the desired miter angle.

1.Move the table to the detented angle that is to be adjusted (Figure 27).

2.The miter detent lever's red override feature MUST be engaged, as described above.

3.Push the Microfine Adjustment knob forward to 'ENGAGED' position. This engages the system into the detent slot (Figure 28).

Note: You may have to rotate the table slightly to engage the system.

4.Turn knob until pointer comes to desired angle.

Rotating the knob forward causes the table to rotate to the left.

Rotating the knob backward causes the table to rotate to the right.

5.Use miter lock knob to lock table in place before cutting.

6.To release table from Microfine Adjustment System, simply pull knob away from table until in snaps into 'OFF' position.

NOTE: Microfine must be returned to the ‘OFF’ position in order to use the standard detent system.

Sliding fences and Base Extensions

! WARNING So as to provide sufficient (minimum 6”) spacing from hand to saw

blade, extend the sliding fences and base extensions when making extreme bevel, miter or compound cuts.

The base extensions can also be used to provide extra support for long workpieces.

Sliding Base:

1.Loosen the base extension clamping levers (Figure 29).

2.Extend sliding base extensions to the desired position.

3.Press the levers down to clamp the extensions into place.

Base Extensions:

If desired, the height of the top of the base extensions can be adjusted slightly by increasing the distance between the extension and the main part of the base.

If the clamping force of the Base Extension Clamping Levers needs to be adjusted, simply pull the red tab outward and rotate it toward the center of the saw. Let the red tab spring back into a new groove. When the red tabs are rotated down to clamp the rods, they will grip the rods with greater strength.

Sliding fence:

1.Loosen the fence locking knobs (behind fence).

2.Slide fence to proper position.

3.Tighten knobs to lock fence into place.

To Temporarily Remove Sliding fence:

Some extreme compound angles make it necessary to remove one of the sliding fences.

1.Unscrew fence knob until at least 1/2” of thread shows.

2.Slide fence to its centermost position.

3.Lift fence to remove.

4.Tighten knob

After the cut is complete, reinstall the sliding fence. To reinstall the sliding fence, reverse this procedure.

During transportation, sliding base ! CAUTION extensions and fences should al-

ways be secured in the fully closed position.

See page 22 for information about other types of workpiece support.

figure 30. Chop Cut

Slide Cut

The slide rail lock knob is loose, the head assembly is pulled towards the operator, the head assembly is lowered to the workpiece and then pushed to the rear of the saw to make the cut.

This type of cut is used mainly for wide pieces.

A positive blade hook of 10 degrees or more is recommended for best performance when making aggressive cuts or cutting thicker materials.

NEVER pull the saw toward you ! WARNING during a cut. The blade can sud-

denly climb up on top of the workpiece and force itself toward you.

follow these instructions for making your slide cut:

1. Properly position workpiece. Make sure workpiece is clamped firmly against the table and 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.

2.Loosen the slide rail lock knob.

3.Grasp the switch handle and pull the head assembly away from the fence, until the blade clears the workpiece or to its maximum extension if blade cannot clear the workpiece (Figure 31).

4.Activate the switch. Lower the assembly all the way down and cut through the edge of the workpiece.

5.Push (but do not force) the head assembly towards the fence to the full rear position to complete the cut.

6.Wait until blade comes to a complete stop before returning head assembly to the raised position and/or removing workpiece.

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 32).

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 32).

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 25).

3.Properly position workpiece. Make sure workpiece is clamped firmly against the table or the fence.

Use clamping position that does ! WARNING not 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 26).

5.Wait until blade comes to a complete stop before returning head assembly to the raised position and/or removing workpiece.

Bevel Cut

A “bevel cut” is a cross-cut made with the blade perpendicular to the fence but tilted away from the vertical position.

A bevel cut is made at 0° miter and any bevel angle in the range up to 47°.

There are factory set bevel stops at 0° and 45° on both the left and right. (See Adjustment section if adjustments are required.)

The front-positioned bevel range selector knob provides three bevel range choices.

There are also positive crown molding bevel stops at 33.9° on both the left and right. Disengage this stop unless using the 33.9° angle (See Cutting Crown Molding for details.)

A bevel cut can be made as either a chop cut or a slide cut depending on the width of the workpiece.

The front-positioned bevel lock lever locks the head assembly at the desired bevel angle.

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 25.)

2.Properly position workpiece. Make sure workpiece is clamped firmly against the table or the fence(Figure 35).

Use clamping position that does ! WARNING not interfere with operation. Be-

fore 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 27 and 28 for miter and bevel cuts.

4.Follow the procedures for either chop cut or slide cut (see page 26).

5.Wait until blade comes to a complete stop before returning head assembly to the raised position and / or removing workpiece.

length Stop (Model 4410 only)

Use only one length stop. Using ! WARNING length stops on both sides of blade,

could trap workpiece and could cause workpiece to be thrown.

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 38).

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 18".

If desired, the length stop and knob can be moved to the left base extension. The optional MS1230 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 MS1229 Extra-Long Base Rod Kit, which increases the maximum length that can be cut using the length stop to approximately 25" on either side of the blade.
