GENERAL SAFETY RULES

WARNING!

READ AND UNDERSTAND ALL INSTRUCTIONS. Failure to follow all instructions listed below, may result in electric shock, fire and/or serious personal injury.

SAVE THESE INSTRUCTIONS

WORK AREA

Keep your 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.

ELECTRICAL SAFETY

A battery operated tool with integral batteries or a separate battery pack must be recharged only with

the specified charger for the battery. A charger that may be suitable for one type of battery may create a risk of fire when used with another battery.

Use battery operated tool only with specifically

designated battery pack. Use of any other batteries may create a risk of fire.

MODEL BATTERY PACK (P100) CHARGER (P110)

P550 130255004 1423701, 140237023 or 140237021

Do not abuse the cord. Never use the cord to carry the charger. Keep cord away from heat, oil, sharp edges, or moving parts. Replace damaged cords

immediately. Damaged cords may create a fire.

PERSONAL SAFETY

Stay alert, watch what you are doing and use common sense when operating a power tool. Do not use tool while tired or under the influence of drugs,

alcohol, or medication. A moment of inattention while operating power tools may result in serious personal injury.

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.

Avoid accidental starting. Be sure switch is in the locked or off position before inserting battery pack.

Carrying tools with your finger on the switch or inserting the battery pack into a tool with 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 may result in personal injury.

3

Do not overreach. Keep proper footing and balance

at all times. Proper footing and balance enable better control of the tool in unexpected situations.

Use safety equipment. Always wear eye protection.

Dust mask, non-skid safety shoes, hard hat, or hearing protection must be used for appropriate conditions.

Do not wear loose clothing or jewelry. Contain long

hair. Loose clothes, jewelry, or long hair can be drawn into air vents.

Do not use on a ladder or unstable support. Stable footing on a solid surface enables better control of the tool in unexpected situations.

TOOL USE AND CARE

Use clamps or other practical way to secure and sup-

port the workpiece to a stable platform. Holding the work by hand or against your body is unstable and may lead to 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 tool if switch does not turn it on or off.

A tool that cannot be controlled with the switch is dangerous and must be repaired.

Disconnect battery pack from tool or place the switch in the locked or off position before making any adjust-

ments, changing accessories, or storing the tool. Such preventive safety measures reduce the risk of starting the tool accidentally.

Store idle tools out of reach of children and other

untrained persons. Tools are dangerous in the hands of untrained users.

When battery pack is not in use, keep it away from other metal objects like: paper clips, coins, keys, nails, screws, or other small metal objects that can make

a connection from one terminal to another. Shorting the battery terminals together may cause sparks, burns, or a fire.

Maintain tools with care. Keep cutting tools sharp

and clean. Properly maintained tools with sharp cutting edges are less likely to bind and are easier to control.

Check for misalignment or binding of moving parts, breakage of parts, and any other condition that may affect the tool’s operation. If damaged, have the tool

serviced before using. Many accidents are caused by poorly maintained tools.

Use only accessories that are recommended by the

manufacturer for your model. Accessories that may be suitable for one tool may create a risk of injury when used on another tool.

n Keep the tool and its handle 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 strong solvents to clean your tool. Following this rule will reduce the risk of loss of control and deterioration of the enclosure plastic.

GENERAL SAFETY RULES

SERVICE

Tool service must be performed only by qualified re-

pair personnel. Service or maintenance performed by unqualified personnel may result in a risk of injury.

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 risk of shock or injury.

SPECIFIC SAFETY RULES

Hold tool by insulated gripping surfaces when performing an operation where the cutting tool may con-

tact hidden wiring. Contact with a “live” wire will also make exposed metal parts of the tool “live” and shock the operator.

Know your power tool. Read operator’s manual carefully. Learn its applications and limitations, as well as the specific potential hazards related to this tool.

Following this rule will reduce the risk of electric shock, fire, or serious injury.

Always wear safety glasses with side shields.

Everyday glasses have only impact resistant lenses. They are NOT safety glasses. Following this rule will reduce the risk of eye injury.

Protect your lungs. Wear a face or dust mask if the

operation is dusty. Following this rule will reduce the risk of serious personal injury.

Protect your hearing. Wear hearing protection during

extended periods of operation. Following this rule will reduce the risk of serious personal injury.

Battery tools do not have to be plugged into an electrical outlet; therefore, they are always in operating condition. Be aware of possible hazards when not using your battery tool or when changing accessories.

Following this rule will reduce the risk of electric shock, fire, or serious personal injury.

Do not place battery tools or their batteries near fire

or heat. This will reduce the risk of explosion and possibly injury.

n Never use a battery that has been dropped or

received a sharp blow. A damaged battery is subject to explosion. Properly dispose of a dropped or damaged battery immediately.

Batteries vent hydrogen gas and can explode in the presence of a source of ignition, such as a pilot light.

To reduce the risk of serious personal injury, never use any cordless product in the presence of open flame. An exploded battery can propel debris and chemicals. If exposed, flush with water immediately.

Use this saw to cut wood, wood products and some plastics only. Do not cut metals, ceramics or masonry products.

Do not charge battery tool in a damp or wet

location. Following this rule will reduce the risk of electric shock.

For best results, your battery tool should be charged in a location where the temperature is more than

50°F but less than 100°F. Do not store outside or in vehicles.

Under extreme usage or temperature conditions, battery leakage may occur. If liquid comes in contact with your skin, wash immediately with soap and water, then neutralize with lemon juice or vinegar. If liquid gets into your eyes, flush them with clean water for at least

10 minutes, then seek immediate medical attention.

Following this rule will reduce the risk of serious personal injury.

n THIS TOOL should have the following markings:

a) Wear eye protection.

b) Keep hands out of path of saw blade

c) Do not operate saw without guards in place.

d) Do not perform any operation freehand.

ASSEMBLY

DUST GUIDE

See Figure 10.

n Remove the battery pack from the tool.

n Place the dust guide (end marked INSERT) over the exhaust port in the upper blade guard. Turn the guide so the open end is facing down or towards the rear of the saw.

DUST BAG

See Figure 11.

Remove the battery pack from the tool. A dust bag is provided for use on this miter saw. It fits over the dust guide on the upper blade guard. To install, squeeze the two metal clips to open the mouth of the bag and slide it on to the dust guide.

Release the clips. The metal ring in the bag should lock in between the grooves on the dust guide.

To remove the dust bag for emptying, simply reverse the above procedure.

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 fence or the saw table. It also prevents the workpiece from creeping toward the 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.

To install the work clamp: n saw table base.

n Rotate the knob on the work clamp to move it in or out as needed.

WARNING:

When using any clamp with a stop block, install the clamp on the same side as the stop block. This will eliminate the possibility of trapping the workpiece, resulting in the blade and workpiece kicking up. Failure to heed this warning can result in serious personal injury.

ASSEMBLY

TO INSTALL BLADE

See Figures 13 - 16.

WARNING:

A 8-1/4 in. blade is the maximum blade capacity of the saw. Never use a blade that is too thick to allow outer blade washer to engage with the flats on the spindle.

Larger blades will come in contact with the blade guards, while thicker blades will prevent the blade bolt from securing the blade on the spindle. Either of these situations could result in a serious accident and can cause serious personal injury.


�n Push down on the saw arm and pull out the lock pin to release saw arm. Raise saw arm to its full raised position.

Be cautious, saw arm is spring loaded to raise.

�n Loosen the phillips screw on the blade bolt cover until blade bolt cover can be raised. See Figure 13.

�n Gently raise the lower blade guard bracket, releasing lower blade guard from notch so that lower blade guard and blade bolt cover can be rotated up and back to expose the blade bolt. See Figure 14.

��n Depress the spindle lock button and rotate the blade bolt until the spindle locks. See Figure 16.

��n Using the blade wrench provided, loosen and remove the blade bolt.

NOTE: The blade bolt has left hand threads. Turn blade bolt clockwise to loosen.

�n� Remove outer blade washer. Do not remove inner blade washer.

��n Wipe a drop of oil onto inner blade washer and outer blade washer where they contact the blade.

WARNING:

If inner blade washer has been removed, replace it before placing blade on spindle. Failure to do so could cause an accident since blade will not tighten properly.

��n Fit saw blade inside lower blade guard and onto spindle.

The blade teeth point downward at the front of saw as shown in figure 15.

CAUTION:

Always install the blade with the blade teeth and the arrow printed on the side of the blade pointing down at the front of the saw. The direction of blade rotation is also stamped with an arrow on the upper blade guard.

OPERATION

CUTTING WITH YOUR COMPOUND

MITER SAW

WARNING:

When using a work clamp or C-clamp to secure your 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.

n Grasp the saw handle firmly, depress the switch lock, then squeeze the switch trigger. Allow several seconds for the blade to reach maximum speed.

n Slowly lower the blade into and through the auxiliary fence.

n Release the switch trigger and allow the blade to stop rotating before raising the blade.

��Repeat the above steps for the right side auxiliary fence making a 45 ° right miter cut.

WARNING:

To avoid serious personal injury, always push the miter table clamp back down before making a cut. Failure to do so could result in movement of the miter table while making a cut.

WARNING:

To avoid serious personal injury, keep 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.

TO CUT SMALL MOLDING AND TRIM


When making compound or 90 ° miter cut on small molding or trim, it is necessary to install an auxiliary fence. The auxiliary fence will hold small workpieces in place during the cutting operation.

NOTE: Do not make a bevel cut through the auxiliary fence unless you anticipate making compound cuts.

To make an auxiliary fence: n Using a piece of wood 1-1/2 in. thick, 2 in. wide, and

7-1/2 in. long, place the wood on the miter table against the left side miter fence. The left end of the wood should be even with the left end of the fence.

n Secure the wood to the miter fence using flat head/drywall screws. From the back of the saw, attach the screws through the holes in the miter fence and into the wood.

n Install a fully charged battery to the miter saw.

n Lift the miter table clamp and rotate the miter table until the pointer aligns with the 45 ° left mark on the miter scale.

n Push the miter table clamp down to lock.

NOTE: You can quickly locate 0 ° , 22-1/2 ° left or right,

30° left or right, and 45 ° left or right by releasing the lock plate as you rotate the control arm. The lock plate will seat itself in one of the positive stop notches, located in the miter table frame.

n 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 fence. 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.

n When cutting long pieces of lumber or molding, support the opposite end of the stock with a roller stand or with a work surface level with the saw table.

n Align cutting line on workpiece with edge of saw blade.

n Grasp the stock firmly with one hand and secure it against the fence. Use the optional work clamp or a

C-clamp to secure the workpiece when possible.

n Before turning on the saw, perform a dry run of the cutting operation just to make sure that no problems will occur when the cut is made.


n Slowly lower the blade into and through the workpiece. n Release the switch trigger and allow the blade to stop rotating before raising the blade out of workpiece. Wait until the electric brake stops blade from turning before removing the workpiece from the miter table.

n Release the switch trigger and allow the saw blade to stop rotating before raising the blade out of workpiece. Wait until the electric brake stops blade from turning before removing the workpiece from miter table.

TO COMPOUND MITER CUT

See Figure 37.

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.

n Pull out the lock pin and lift saw arm to its full height. n Lift the miter table clamp.

�n Rotate the miter table until the pointer aligns with zero on the miter scale.


NOTE: You can quickly locate 0˚, 15˚, 22-1/2˚, left or right,

30˚ and 45˚ left or right by releasing the miter lock plate as you rotate the control arm. The miter lock plate will seat itself in one of the positive stop notches, located in miter table frame.

n Loosen the bevel lock knob and move the saw arm to the left to the desired bevel angle.

n Bevel angles can be set from 0˚ to 45˚.

OPERATION n Grasp the stock firmly with one hand and secure it against the fence. Use the optional work clamp or a C-clamp to secure the workpiece when possible. See Figure 35. n Before turning on the saw, perform a dry run of the cutting operation just to make sure that no problems will occur when the cut is made.


n Slowly lower the blade into and through the workpiece.


n Release the switch trigger and allow the saw blade to stop rotating before raising the blade out of workpiece. Wait until the electric brake stops blade from turning before removing the workpiece from miter table.

TO SUPPORT LONG WORKPIECES

See Figure 39.

Long workpieces need extra supports. Supports should be placed along the workpiece so it does not sag. The support should let the workpiece lay flat on the base of the saw and work table during the cutting operation. Use the optional work clamp or a C-clamp to secure the workpiece.

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 40.

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 moldings 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

31.62

° 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 on page 29 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.

CUTTING WARPED MATERIAL


When cutting warped material, always make sure it is positioned on the miter table with the convex side against the fence as shown in figure 41.

If the warped material is positioned the wrong way as shown in figure 42, it will pinch the blade near the completion of the cut.

WARNING:

To avoid a kickback and to avoid serious personal injury, never position the concave edge of bowed or warped material against the fence.

CLAMPING WIDE WORKPIECES

When cutting wide workpieces, such as 52 in. x 6 in., boards should be clamped with a C-clamp.

ADJUSTMENTS

WARNING:

To prevent accidental starting that could cause serious personal injury, always remove the battery pack from the tool when making adjustments.

The compound miter saw has been adjusted at the factory for making very accurate cuts. However, some of the components might have been jarred out of alignment during shipping. Also, over a period of time, readjustment will probably become necessary due to wear. After unpacking the saw, check the following adjustments before you begin using saw. Make any readjustments that are necessary and periodically check the parts alignment to make sure that the saw is cutting accurately.

CAUTION:

Do not start the compound miter saw without checking for interference between the blade and the throat plate.

Damage could result to the blade if it strikes the throat plate during operation of the saw.

PIVOT ADJUSTMENTS

NOTE: These adjustments were made at the factory and normally do not require readjustment.

TRAVEL PIVOT ADJUSTMENT

n The saw arm should rise completely to the up position by itself.

n If the saw arm does not raise by itself or if there is play in the pivot joints, have saw repaired at your nearest

RYOBI AUTHORIZED SERVICE CENTER.

BEVEL PIVOT ADJUSTMENT

n The compound miter saw should bevel easily by loosening the bevel lock knob and tilting the saw arm to the left.

n If movement is tight or if there is play in the pivot, have saw repaired by at your nearest RYOBI AUTHORIZED

SERVICE CENTER.

DEPTH STOP

The depth stop limits the blade’s downward travel. It allows the blade to go below the miter table enough to maintain full cutting capacities. The depth stop positions the blade 1/4 in. from the miter table support.

NOTE: The miter table support is located inside miter table.

The depth stop is factory set to provide maximum cutting capacity for the 8-1/4 in. blade provided with the saw.

Therefore, the saw with blade provided should never need adjustments.

However, when the diameter of the blade has been reduced due to sharpening, it may be necessary to adjust the depth stop to provide maximum cutting capacity. Also, when a new blade is installed, it is necessary to check the clearance of the blade to the miter table support before starting the saw. Make adjustments if needed.

DEPTH STOP ADJUSTMENTS

See Figure 43.


n To adjust the depth stop use a 17 mm wrench or adjustable wrench and loosen the hex nut at the rear of the miter saw arm.

�n Use the 5 mm hex key provided to adjust the depth stop adjustment screw. The saw blade is lowered by turning the screw counterclockwise and raised by turning the screw clockwise.

n Lower the blade into the throat plate of the miter table.

Check blade clearance and maximum cutting distance

(distance from fence where blade enters) to front of miter table slot.

n Readjust if necessary.
