ING BODY CONTACT WITH GROUNDED SURFACES.

For example: pipes, radiators, ranges, refrigerator enclosures.

 KEEP GUARDS IN PLACE and in good working order.

 REMOVE ADJUSTING KEYS AND WRENCHES. Form habit of checking to see that keys and adjusting wrenches are removed from tool before turning it on.

 KEEP WORK AREA CLEAN. Cluttered areas and benches invite accidents.

DO NOT leave tools or pieces of wood on the tool while it is in operation.

 DO NOT USE IN DANGEROUS ENVIRONMENTS. Do not use power tools in damp or wet locations or expose to rain. Keep the work area well lit.

 KEEP CHILDREN AND VISITORS AWAY. All visitors should wear safety glasses and be kept a safe distance from work area. Do not let visitors contact tool or extension cord while operating.

 MAKE WORKSHOP CHILDPROOF with padlocks, master switches, or by removing starter keys.

 DON’T FORCE THE TOOL. It will do the job better and safer at the feed rate for which it was designed.

 USE THE RIGHT TOOL. Do not force the tool or attachment to do a job for which it was not designed.

 USE THE PROPER EXTENSION CORD. Make sure your extension cord is in good condition. Use only a cord heavy enough to carry the current your product will draw. An undersized cord will cause a drop in line voltage resulting in loss of power and overheating. A wire gauge size

(A.W.G.) of at least 14 is recommended for an extension cord 25 feet or less in length. If in doubt, use the next heavier gauge. The smaller the gauge number, the heavier the cord.

 DRESS PROPERLY. Do not wear loose clothing, neckties, or jewelry that can get caught and draw you into moving parts. Rubber gloves and nonskid footwear are recommended when working outdoors. Also wear protective hair covering to contain long hair.

 ALWAYS WEAR SAFETY GLASSES WITH SIDE

SHIELDS. Everyday eyeglasses have only impact- resistant lenses, they are NOT safety glasses.

 SECURE WORK. Use clamps or a vise to hold work when practical, it is safer than using your hand and frees both hands to operate the tool.

 DO NOT OVERREACH. Keep proper footing and balance at all times.

 MAINTAIN TOOLS WITH CARE. Keep tools sharp and clean for better and safer performance. Follow instructions for lubricating and changing accessories.

 DISCONNECT TOOLS. When not in use, before servicing, or when changing attachments, blades, bits, cutters, etc., all tools should be disconnected from power source.

 AVOID ACCIDENTAL STARTING. Be sure switch is off when plugging in any tool.

 USE RECOMMENDED ACCESSORIES. Consult the operator’s manual for recommended accessories. The use of improper accessories may result in injury.

 NEVER STAND ON TOOL. Serious injury could occur if the tool is tipped.

 CHECK DAMAGED PARTS. Before further use of the tool, a guard or other part that is damaged should be carefully checked to determine that it will operate properly and perform its intended function. Check for alignment of moving parts, binding of moving parts, breakage of parts, mounting and any other conditions that may affect its operation. A guard or other part that is damaged must be properly repaired or replaced by an authorized service center to avoid risk of personal injury.

 USE THE RIGHT DIRECTION OF FEED. Feed work into a blade, cutter, or sanding spindle against the direction or rotation of the blade, cutter, or sanding spindle only.

 NEVER LEAVE TOOL RUNNING UNATTENDED. TURN

THE POWER OFF. Don't leave tool until it comes to a complete stop.

 PROTECT YOUR LUNGS. Wear a face or dust mask if the cutting operation is dusty.

 PROTECT YOUR HEARING. Wear hearing protection during extended periods of operation.

 DO NOT ABUSE CORD. Never carry tool by the cord or yank it to disconnect from receptacle. Keep cord from heat, oil, and sharp edges.

 USE OUTDOOR EXTENSION CORDS. When tool is used outdoors, use only extension cords with approved ground connection that are intended for use outdoors and so marked.

KEEP BLADES CLEAN, SHARP, AND WITH

SUFFICIENT SET. Sharp blades minimize stalling and kickback.

GENERAL SAFETY RULES

 NEVER USE IN AN EXPLOSIVE ATMOSPHERE.

Normal sparking of the motor could ignite fumes.

 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 your 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 COM-

PONENT IS IN CONTACT WITH THE WORKPIECE.

 DO NOT OPERATE A TOOL WHILE UNDER THE

INFLUENCE OF DRUGS, ALCOHOL, OR ANY

MEDICATION.

 WHEN SERVICING use only identical replacement parts.

Use of any other parts may create a hazard or cause product damage.

 USE ONLY RECOMMENDED ACCESSORIES listed in this manual or addendums. Use of accessories that are not listed may cause the risk of personal injury.

Instructions for safe use of accessories are included with the accessory.

 DOUBLE CHECK ALL SETUPS. Make sure blade is tight and not making contact with saw or workpiece before connecting to power supply.

SPECIFIC SAFETY RULES

 FIRMLY CLAMP OR BOLT your tool to a workbench or table at approximately hip height.

 KEEP HANDS AWAY FROM CUTTING AREA. Do not reach underneath work or in blade cutting path with your hands and fingers for any reason. Always turn the power off.

 ALWAYS SUPPORT LONG WORKPIECES while cutting to minimize risk of blade pinching and kickback. Saw may slip, walk or slide while cutting long or heavy boards.

 ALWAYS USE A CLAMP to secure the workpiece when possible.

 BE SURE THE BLADE CLEARS THE WORKPIECE.

Never start the saw with the blade touching the workpiece. Allow motor to come up to full speed before starting cut.

 MAKE SURE THE MITER TABLE AND SAW ARM (BEVEL

FUNCTION) ARE LOCKED IN POSITION BEFORE

OPERATING YOUR SAW. Lock the miter table by securely tightening the miter lock levers. Lock the saw arm (bevel function) by securely tightening the bevel lock knob.

 NEVER USE A LENGTH STOP ON THE FREE SCRAP

END OF A CLAMPED WORKPIECE. NEVER hold onto or bind the free scrap end of the workpiece in any operation. If a work clamp and length stop are used together, they must both be installed on the same side of the saw table to prevent the saw from catching the loose end and kicking up.

 NEVER cut more than one piece at a time. DO NOT

STACK more than one workpiece on the saw table at a time.

 NEVER PERFORM ANY OPERATION FREEHAND.

Always place the workpiece to be cut on the miter table and position it firmly against the fence as a backstop.

Always use the fence.

4

SPECIFIC SAFETY RULES

 NEVER hand hold a workpiece that is too small to be clamped. Keep hands clear of the cutting area.

 NEVER reach behind, under, or within three inches of the blade and its cutting path with your hands and fingers for any reason.

 NEVER reach to pick up a workpiece, a piece of scrap, or anything else that is in or near the cutting path of the blade.

 AVOID AWKWARD OPERATIONS AND HAND

POSITIONS where a sudden slip could cause your hand to move into the blade. ALWAYS make sure you have good balance. NEVER operate your miter saw on the floor or in a crouched position.

 NEVER stand or have any part of your body in line with the path of the saw blade.

 ALWAYS release the power switch and allow the saw blade to stop rotating before raising it out of the workpiece.

 DO NOT TURN THE MOTOR SWITCH ON AND OFF

RAPIDLY. This could cause the saw blade to loosen and could create a hazard. Should this ever occur, stand clear and allow the saw blade to come to a complete stop. Disconnect your saw from the power supply and securely retighten the blade bolt.

 IF ANY PART OF THIS MITER SAW IS MISSING or should break, bend, or fail in any way, or should any electrical component fail to perform properly, shut off the power switch, remove the miter saw plug from the power source and have damaged, missing, or failed parts replaced before resuming operation.

 IF THE POWER SUPPLY CORD IS DAMAGED, it must be replaced only by the manufacturer or by an authorized service center to avoid risk.

 ALWAYS STAY ALERT! Do not allow familiarity (gained from frequent use of your saw) to cause a careless mistake. ALWAYS REMEMBER that a careless fraction of a second is sufficient to inflict severe injury.

 MAKE SURE THE WORK AREA HAS AMPLE LIGHTING to see the work and that no obstructions will interfere with safe operation BEFORE performing any work using your saw.

 ALWAYS TURN OFF THE SAW before disconnecting it to avoid accidental starting when reconnecting to power supply. NEVER leave the saw unattended while connected to a power source.

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 tool 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 your 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 tool 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 tool, 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.

WARNING:

Keep the extension cord clear of the working area.

Position the cord so that it will not get caught on lumber, tools or other obstructions while you are working with a power tool. Failure to do so can result in serious personal injury.

WARNING:

Check extension cords before each use. If damaged replace immediately. Never use tool with a damaged cord since touching the damaged area could cause electrical shock resulting in serious injury.

DUST BAG

See Figure 12.

A dust bag is provided for use on this miter saw. It fits over the dust guide on the upper blade guard. To install it, squeeze the two metal clips to open the mouth of the bag and slide it on 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 13.

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. It also prevents 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.

To install the work clamp: saw table base.

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

NOTE: The work clamp has a quick release lever that makes positioning of the work clamp effortless.

WARNING:

A 12 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 hex bolt from securing the blade on the spindle.

Either of these situations could result in a serious accident and can cause serious personal injury.

 Unplug the saw.

 Raise saw arm.

 Rotate lower blade guard up and loosen screw. Rotate blade bolt cover up and back to expose the hex bolt.

 Depress the spindle lock button and rotate the hex bolt until the spindle locks.

ALIGNING THE LASER GUIDE LINE

See Figure 16.

The laser guide will generate a red colored line on the work surface when the blade is spinning. The red 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.

Make several practice cuts on different styles and thickness of material.

18

ASSEMBLY

Follow the directions below for using the laser guide:

Removing Your Mark:

Position the laser line near the left edge of your mark on the work surface in order to remove the mark.

To Cut Your Mark:

Position the laser line near or over your mark on the work surface in order to cut the mark.

To Leave Your 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.

CUTTING A SLOT IN THE ZERO CLEARANCE

THROAT PLATE

In order to use your compound miter saw, you must cut a slot through the zero clearance throat plate to allow for blade clearance. To cut the slot, set your saw at 0 ° miter, turn saw on and allow the blade to reach full speed, then carefully make a straight cut as far as it will go through the throat plate. Turn your saw off and allow the blade to come to a complete stop before raising the saw arm.

Next, adjust the bevel angle to 45 ° , turn your saw on and allow the blade to reach full speed, then carefully make another cut through the zero clearance throat plate. The slot in the throat plate will then be wide enough to allow the blade to pass through it at any angle from 0 ° to 45 ° .

NOTE: Many of the illustrations in this manual show only portions of your compound miter saw. This is intentional so that we can clearly show points being made in the illustrations. Never operate your saw without all guards securely in place and in good operating condition.

OPERATION

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:

Before starting any cutting operation, clamp or bolt your miter saw to a workbench. Never operate your miter saw on the floor or in a crouched position.

Failure to heed this warning can result in serious personal injury.

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.

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.

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

This product has been designed only for the purposes listed below:

 Cross cutting wood and plastic.

 Cross cutting miters, joints, etc. for picture frames, moldings, door casings, and fine joinery.

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 your dealer.

22

WARNING:

Do not start your 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.

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.

WARNING:

To avoid serious personal injury, always tighten the miter lock handle securely before making a cut.

Failure to do so could result in movement of the control arm or miter table while making a cut.

 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. See Figure 32.

 Align cutting line on the workpiece with the edge of saw blade.

 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.

 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.

 Grasp the saw handle firmly. Depress the switch lock with thumb then squeeze the switch trigger. Allow several seconds for the blade to reach maximum speed.

 Slowly lower the blade into and through the workpiece.

 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 the miter table.

TO CROSSCUT

See Figure 26.

A crosscut is made by cutting across the grain of the workpiece. A straight crosscut is made with the miter table set at the 0 ° position. Miter crosscuts are made with the miter table set at some angle other than zero.

 Pull out the lock pin and lift saw arm to its full height.

 Loosen the miter lock handle. Rotate the miter lock handle approximately one-half turn to the left to loosen.

 Press the miter lock plate down with your thumb and hold.

 Rotate the control arm until the pointer aligns with the desired angle on the miter scale.

 Release the miter lock plate.

NOTE: You can quickly locate 0°, 15 ° , 22.5

° , 31.6

° , 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.

 Tighten the miter lock handle securely.

 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. See Figures 34 - 35.

OPERATION


 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

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.




 Rotate the control arm until the pointer aligns with the desired angle on the miter scale.


NOTE: You can quickly locate 0°, 15 ° , 22.5

° , 31.6

° , 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.


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

 Bevel angles can be set from -2˚ to 47˚.

 Once the saw arm has been set at the desired angle, securely tighten the bevel lock knob.

OPERATION

CUTTING CROWN MOLDING

Your 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 33.

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 31.6

° 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.

OPERATION

MAKING A CROWN MOLDING SUPPORT JIG

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, 5 in. wide, and 23-1/2 in. long, place the wood on the miter table against the miter fence.

NOTE: Use a piece of wood 28 in. long if using the extension table.

 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.

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 below to select the proper miter angle.

 Loosen the miter lock handle and position the miter table to the desired setting. Securely tighten the miter lock handle.

 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 the workpiece.

Wait until the electric brake stops blade from turning before removing the workpiece from the miter table.

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 34.

If the warped material is positioned the wrong way as shown in figure 35, it will pinch the blade near the completion of the cut.

MAINTENANCE

WARNING:

When servicing, use only identical replacement parts. Use of any other part may create a hazard or cause product damage.

WARNING:

Do not at any time let brake fluids, gasoline, petroleum-based products, penetrating oils, etc., come in contact with plastic parts. They contain chemicals that can damage, weaken or destroy plastic.

WARNING:

Always wear safety goggles or safety glasses with side shields during power tool operation or when blowing dust. If operation is dusty, also wear a dust mask.

GENERAL MAINTENANCE

Avoid using solvents when cleaning plastic parts. Most plastics are susceptible to damage from various types of commercial solvents and may be damaged by their use. Use clean cloths to remove dirt, carbon dust, etc.

LUBRICATION

All of the bearings in this tool are lubricated with a sufficient amount of high grade lubricant for the life of the unit under normal operating conditions. Therefore, no further lubrication is required.

WARNING:

To ensure safety and reliability, all repairs should be performed by a qualified service technician at an authorized service center to avoid risk of personal injury.

30

MAINTENANCE

Some areas will require infrequent lubrications. You will need to apply:

 Automotive oil directly to the slide bars.

 Light oil or a pressurized light spray oil to the arm pivot shaft.

 Light oil or a pressurized light spray oil to the torsion spring.

EXTENSION CORDS

The use of any extension cord will cause some loss of power.

To keep the loss to a minimum and to prevent tool overheating, use an extension cord that is heavy enough to carry the current the tool will draw.

A wire gauge size (A.W.G.) of at least 14 is recommended for an extension cord 25 feet or less in length. When working outdoors, use an extension cord that is suitable for outdoor use. The cord's jacket will be marked WA.

WARNING:

Keep extension cords away from the cutting area and position the cord so that it will not get caught on lumber, tools, etc., during cutting operation.

Failure to heed this warning may result in serious personal injury.

BRUSH REPLACEMENT

See Figure 37.

The saw has externally accessible brush assemblies that should be periodically checked for wear.

Proceed as follows when replacement is required:

 Unplug the saw.

WARNING:

Failure to unplug the saw could result in accidental starting causing serious injury.

 Remove brush cap with a screwdriver. Brush assembly is spring loaded and will pop out when you remove brush cap.

 Remove brush assembly.

 Check for wear. Replace both brushes when either has less than 1/4 in. length of carbon remaining. Do not replace one side without replacing the other.

 Reassemble using new brush assemblies. Make sure curvature of brush matches curvature of motor and that brush moves freely in brush tube.

 Make sure brush cap is oriented correctly (straight) and replace.

 Tighten brush cap securely. Do not overtighten.

CAUTION:

Check extension cords before each use. If damaged, replace immediately. Never use tool with a damaged cord since touching the damaged area could cause electrical shock resulting in serious injury.
