IMPORTANT SAFETY INSTRUCTIONS
_ARNING: When using electric tools, basic safety precautions should
always be followed to reduce risk of fire, electric shock, and personal injury,
including the following:
READ ALL INSTRUCTIONS
Double Insulation
Double insulated tools are constructed throughout with two separate layers of electrical
insulation or one double thickness of insulation between you and the tool's electrical system.
Tools built with this insulation system are not intended to be grounded. As a result, your tool is
equipped with a two prong plug which permits you to use extension cords without concern for
maintaining a ground connection.
NOTE: Double insulation does not take the place of normal safety precautions when operating
this tool. The insulation system is for added protection against injury resulting from a possible
electrical insulation failure within the tool.
Z&CAUTION: WHEN SERVICING USE ONLY IDENTICAL REPLACEMENT PARTS. Repair or
replace damaged cords.
Polarized Plugs
Polarized plugs (one blade is wider than the other) are used on equipment to reduce the risk of
electric shock. When provided, this plug will fit in the 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.
Safety Instructions For All Tools
This miter saw accepts the DEWALT worklight and laser attachments.
AWARNING: To reduce the risk of eye injury, ALWAYS use eye protection when operating
the miter saw.
• KEEP GUARD IN PLACE and in working order.
• REMOVE ADJUSTING KEYS AND WRENCHES. Form habit of checking to see that keys
and adjusting wrenches are removed from spindle before turning tool on. Tools, scrap pieces,
and other debris can be thrown at high speed, causing injury.
• KEEP WORK AREA CLEAN. Cluttered areas and benches invite accidents.
•DO NOT USE THE MACHINE IN A DANGEROUS ENVIRONMENT. The use of power tools
in damp or wet locations or in rain can cause shock or electrocution. Keep your work area
well-lit to avoid tripping or placing arms, hands, and fingers in danger.
• KEEP CHILDREN AWAY. All visitors should be kept at a safe distance from work area. Your
shop is a potentially dangerous environment.
•MAKE WORKSHOP CHILDPROOF with padlocks, master switches, or by removing starter
keys. The unauthorized start-up of a machine by a child or visitor may result in injury.
•DON'T FORCE TOOL. It will do the job better and be safer at the rate for which it was
designed.
•USE RIGHT TOOL. Don't force tool or attachment to do a job for which it was not designed.
Using the incorrect tool or attachment may result in personal injury.
•WEAR PROPER APPAREL. No loose clothing, gloves, neckties, rings, bracelets, or other
jewelry to get caught in moving parts. Non-slip footwear is recommended. Wear protective
hair covering to contain long hair. Air vents may cover moving parts and should also be
avoided.
•ALWAYS USE SAFETY GLASSES. Everyday eyeglasses are NOT safety glasses. Also
use face or dust mask if cutting operation is dusty. ALWAYS WEAR CERTIFIED SAFETY
EQUIPMENT:
• ANSI Z87.1 eye protection (CAN/CSA Z94.3)
• ANSI $12.6 ($3.19) hearing protection
• NIOSH/OSHA/MSHA respiratory protection
• SECURE THE WORKPIECE. Use clamps or a vise to hold the workpiece on the table
and against the fence or when your hand will be dangerously close to the blade within 6"
(152 mm). It is safer than using your hand and it frees both hands to operate tooL
• DON'T OVERREACH. Keep proper footing and balance at all times. Loss of balance may
cause personal injury.
• MAINTAIN TOOLS WITH CARE. Keep tools sharp and clean for best and safest performance.
Follow instructions for lubricating and changing accessories. Poorly maintained tools and
machines can further damage the tool or machine and/or cause injury.
• TURN THE MACHINE "OFF'; AND DISCONNECT THE MACHINE FROM THE POWER
SOURCE before installing or removing accessories, before adjusting or changing set-ups,
when making repairs or changing locations. An accidental start-up can cause injury. Do not
touch the plug's metal prongs when unplugging or plugging in the cord.
• REDUCE THE RISK OF UNINTENTIONAL STARTING. Make sure that the switch is in the
"OFF" position before plugging in the power cord.
• USE PROPER EXTENSION CORD. Make sure your extension cord is in good condition, ff
your product is equipped with a cordset, use only 3-wire extension cords that have 3-prong
grounding-type plugs and 3-pole receptacles that accept the tool's plug. When using an
extension cord, be sure to use one 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.
The following table shows the correct size to use depending on cord length and nameplate
ampere rating, ff in doubt, use the next heavier gauge. The smaller the gauge number, the
heavier the cord.

Not Recommended
• CHECK FOR 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 should be properly repaired or replaced. Do not use tool if switch does
not turn it on and off.
• USE RECOMMENDED ACCESSORIES. Use only accessories that are recommended
by the manufacturer for your model Accessories that may be suitable for one tool may be
hazardous when used on another tool Consult the instruction manual for recommended
accessories. The use of improper accessories may cause risk of injury to persons.
• NEVER STAND ON TOOL. Serious injury could occur if the tool is tipped or if the cutting tool
is unintentionally contacted.
• NEVER LEAVE TOOL RUNNING UNATTENDED. TURN POWER OFF. Don't leave tool until
it comes to a complete stop. Serious injury can result.
• DO NOT OPERATE ELECTRIC TOOLS NEAR FLAMMABLE LIQUIDS OR IN GASEOUS
OR EXPLOSIVE ATMOSPHERES. Motors in these tools may spark and ignite fumes.

AUTOMATIC ELECTRIC BRAKE
Your saw is equipped with an automatic electric blade brake which stops the saw b_ade within
5 seconds of trigger release, This is not adjustable,
On occasion, there may be a delay after trigger rele_ to brake engagement On rare occasions,
the brake may not engage at all and the blade witl coast to a stop,
If a delay or 'skipping' occurs, turn the saw on and off 4 or 5 times, if the cotillion _rsiste, have
the tool serviced by an authorized D_WALT service center:

GUARD ACTUATION AND VISIBILITY
ACAUTION: Pinch Hazard. To reduce the risk of injury, keep thumb underneath the handle
when pulling the handle down. The lower guard will move up as the handle is pulled down which
could cause pinching.
The blade guard on your saw has been designed to automatically raise when the arm is brought
down and to lower over the blade when the arm is raised.
The guard can be raised by hand when installing or removing saw blades orfor inspection of the
saw. NEVER RAISE THE BLADE GUARD MANUALLY UNLESS THE SAW IS TURNED OFF.
NOTE: Certain special cuts of large material will require that you manually raise the guard.
Refer to Cutting Large Material under Special Cuts.
The front section of the guard is Iouvered for visibility while cutting. Although the louvers dramati-
cally reduce flying debris, they are openings in the guard and safety glasses should be worn at
all times when viewing through the louvers.
MITER LOCK ADJUSTMENT (FIG. 11)
The miter lock rod should be adjusted if the table of the saw can be moved when the miter
lock handle is locked down. To adjust, put the miter lock handle in the up position. Using a
slotted screwdriver, adjust the lock rod in 1/8 clockwise turn increments to increase the lock
force.To ensure the miter lock is functioning properly, re-lock miter lock handle to a non-detent
miter angle.
Brushes
i_,WARNING: Toreduce the risk of serious personal injury, turn off the tool and disconnect
it from the power source before attempting to move it, change accessories or make any
adjustments accept as written in laser adjustment instructions.
Inspect carbon brushes regularly by unplugging tool, removing the motor end cap (Fig. 2), lift
the brush spring and withdraw the brush assembly. Keep brushes clean and sliding freely in
their guides. Always replace a used brush in the same orientation in the holder as it was prior
to its removal. Carbon brushes have varying symbols stamped into their sides, and if the brush
is worn down to approximately 1/2" (12.7 mm), the spring will no longer exert pressure and they
must be replaced. Use only identical DEWALT brushes. Use of the correct grade of brush is
essential for proper operation of electric brake. New brush assemblies are available at DEWALT
service centers. The tool should be allowed to "run in" (run at no load) for 10 minutes before
use to seat new brushes. The electric brake may be erratic in operation until the brushes are
properly seated (worn in). Always replace the brush inspection cap after inspection or servicing
the brushes.
While "running in" DO NOT TIE, TAPE, OR OTHERWISE LOCK THE TRIGGER SWITCH ON.
HOLD BY HAND ONLY.
Controls
Your compound miter saw has several main controls, which will be discussed briefly here. For
more information on these controls, see the respective sections later in the manual.
MITER CONTROL (FIG. 5)
The miter lock/adjustment lever and trigger allows you to miter your saw 50° left and right. To
miter the saw, unlock miter lock lever (J) by pulling upward, squeeze the detent trigger (K) and
set the miter angle desired on the miter scale. Lock miter lock handle by pressing downward.
Override the detent trigger by rotating knob (Fig. 10, V).
TRIGGER SWITCH (FIG. 2)
The trigger switch turns your saw on and off. A hole is provided in the trigger for insertion of a
padlock to secure the saw.
BEVEL LOCK (FIG. 8)
The bevel lock knob (L) allows you to bevel the saw 48 ° left or right. To loosen the handle and
adjust the bevel setting, turn the handle counterclockwise, the saw head bevels easily to the left
or to the right once the 0° bevel override knob (S) is pulled. To tighten, turn the handle clockwise.
Bevel degree markings are on the bottom front of the saw arm (Fig. 7, M).
0° BEVEL OVERRIDE (FIG. 8)
The bevel stop override (S) allows you to bevel the saw to the right past the 0° mark.
The saw will automatically stop at 0° when brought up from the left. To move past 0° to the right,
pull the bevel stop knob. The stop knob can be locked out by pulling the knob out and rotating
it 180°.
45°BEVEL STOP OVERRIDES (FIG. 8)
The bevel stop overrides (N) are held secure with their attachment screw to prevent inadvertent
movement. Use the bit on the blade wrench to loosen the attachment screw. This allows the
slides, to be pulled outward and the saw head to pivot past the 45° mark. Be sure to retighten
the attachment screw when finished.
33.85 ° BEVEL STOPS (FIG. 8)
The two pawls (P) are used to stop the saw head bevel setting at 33.85 °. This setting is used
primarily for cutting crown moldings laid flat on the table.
HEAD DOWNLOCK PIN (FIG. 8)
To lock the saw head in the down position, push the head down, push the pin (U) in and release
the saw head. This will hold the saw head safely down for moving the saw from place to place.
To release, press the saw head down and pull the pin out.
OPERATION
_WARNING: Toreduce the risk of serious personal injury, turn off the tool and disconnect
it from the power source before attempting to move it, change accessories or make any
adjustments accept as written in laser adjustment instructions.
WARNING: Always use eye protection. All users and bystanders must wear eye protection
that conforms to ANSI Z87.1 (CAN/CSA Z94.3).
Plug the saw into any household 60 Hz power source. Refer to the nameplate for voltage. Be
sure the cord will not interfere with your work.
SWITCH
To turn the saw on, depress the trigger switch. To turn the tool off, release the switch. Allow the
blade to spin up to full operating rpm before making the cut. Release the trigger switch and allow
the brake to stop the blade before raising the saw head. There is no provision for locking the
switch on, but a hole is provided in the trigger for insertion of a padlock to lock the saw off.
CUTTING WITH YOUR SAW
NOTE: Although this saw will cut wood and many non-ferrous materials, we will limit our
discussion to the cutting of wood only. The same guidelines apply to the other materials. DO
NOT CUT FERROUS (IRON AND STEEL) MATERIALS OR MASONRY WITH THIS SAW. Do
not use any abrasive blades.
CROSSCUTS
Cutting of multiple pieces is not recommended but can be done safely by ensuring that each
piece is held firmly against the table and fence. A crosscut is made by cutting wood across the
grain at any angle. A straight crosscut is made with the miter arm at the zero degree position.
Set the miter arm at zero, hold the wood on the table and firmly against the fence. Turn on the
saw by squeezing the trigger.
_&CAUTION: Always use a work clamp to maintain control and reduce the risk of workpiece
damage and personal injury.
When the saw comes up to speed (about 1 second) lower the arm smoothly and slowly to cut
through the wood. Let the blade come to a full stop before raising arm.
Miter crosscuts are made with the miter arm at some angle other than zero. This angle is often 45°
for making corners, but can be set anywhere from zero to 50 ° left or right. After selecting the desired
miter angle, be sure to lock miter lock lever. Make the cut as described above.
To cut through an existing pencil line on a piece of wood, match the angle as close as possible.
Cut the wood a little too long and measure from the pencil line to the cut edge to determine
which direction to adjust the miter angle and recut. This will take some practice, but it is a
commonly used technique.
BEVEL CUTS
A bevel cut is a crosscut made with the saw blade at a bevel to the wood. In order to set the
bevel, loosen the bevel clamp knob and move the saw to the left as desired. (It is necessary
to move the fence to allow clearance). Once the desired bevel angle has been set, tighten the
bevel clamp knob firmly.
Bevel angles can be set from 48° right to 48° left and can be cut with the miter arm set between
zero and 50 ° right or left. At some extreme angles, the right or left side fence might have to be
removed. To remove the left or right fence, unscrew the knobs several turns and slide the fence
out.
QUALITY OF CUT
The smoothness of any cut depends on a number of variables. Things like material being cut, blade
type, blade sharpness and rate of cut all contribute to the quality of the cut.
When smoothest cuts are desired for molding and other precision work, a sharp (60 tooth
carbide) blade and a slower, even cutting rate will produce the desired results.
Ensure that material does not creep while cutting, clamp it securely in place. Always let the blade
come to a full stop before raising arm.
If small fibers of wood still split out at the rear of the workpiece, stick a piece of masking tape
on the wood where the cut will be made. Saw through the tape and carefully remove tape when
finished.
For varied cutting applications, refer to the list of recommended saw blades for your saw and
select the one that best fits your needs. Refer to Saw Blades under OptionalAccessories.
BODY AND HAND POSITION (FIG. 12)
Proper positioning of your body and hands when operating the miter saw will make cutting
easier, more accurate and safer. Never place hands near cutting area. Place hands no closer
than 6" (152 mm) from the blade. Hold the workpiece tightly to the table and the fence when
cutting. Keep hands in position until the trigger has been released and the blade has completely
stopped. ALWAYS MAKE DRY RUNS (UNPOWERED) BEFORE FINISH CUTS SO THAT
YOU CAN CHECK THE PATH OF THE BLADE. DO NOT CROSS HANDS, AS SHOWN IN
FIGURE 12A.
Keep both feet firmly on the floor and maintain proper balance. As you move the miter arm left
and right, follow it and stand slightly to the side of the saw blade. Sight through the guard louvers
when following a pencil line.
CLAMPING THE WORKPIECE
AWARNING: To reduce the risk of serious personal injury, turn off the tool and disconnect
it from the power source before attempting to move it, change accessories or make any
adjustments accept as written in laser adjustment instructions.
_,WARNING: A workpiece that is clamped, balanced and secure before a cut may become
unbalanced after a cut is completed. An unbalanced load may tip the saw or anything the saw
is attached to, such as a table or workbench. When making a cut that may become unbalanced,
properly support the workpiece and ensure the saw is firmly bolted to a stable surface. Personal
injury may occur.
_,WARNING: The clamp foot must remain clamped above the base of the saw whenever the
clamp is used. Always clamp the workpiece to the base of the saw-not to any other part of the
work area. Ensure the clamp foot is not clamped on the edge of the base of the saw.
_, CAUTION: Always use a work clamp to maintain control and reduce the risk of workpiece
damage and personal injury,
If you cannot secure the workpiece on the table and against the fence by hand, (irregular shape,
etc.) or your hand would be less than 6" (152 mm) from the blade, a clamp or other fixture must
be used.
For best results use the DW7082 clamp made for use with your saw. It is available for purchase
at your local retailer or DEWALT service center.
Other aids such as spring clamps, bar clamps or C-clamps may be appropriate for certain sizes
and shapes of material. Use care in selecting and placing these clamps. Take time to make a dry
run before making the cut. The left or right fence will slide from side to side to aid in clamping.
TO INSTALL CLAMP (SOLD SEPARATELY)
1. Insert it into the hole behind the fence. The clamp should be facing toward the back of the
miter saw. The groove on the clamp rod should be fully inserted into the base. Ensure this
groove is fully inserted into the base of the miter saw. If the groove is visible, the clamp will
not be secure.
2. Rotate the clamp 180° toward the front of the miter saw.
3. Loosen the knob to adjust the clamp up or down, then use the fine adjust knob to firmly
clamp the workpiece.
NOTE: Place the clamp on the opposite side of the base when beveling. ALWAYS MAKE DRY
RUNS (UNPOWERED) BEFORE FINISH CUTS TO CHECK THE PATH OF THE BLADE.
ENSURE THE CLAMP DOES NOT INTERFERE WITH THE ACTION OF THE SAW OR
GUARDS.
AWARNING: A workpiece that is clamped, balanced and secure before a cut may become
unbalanced after a cut is completed. An unbalanced load may tip the saw or anything the saw
is attached to, such as a table or workbench. When making a cut that may become unbalanced,
properly support the workpiece and ensure the saw is firmly bolted to a stable surface.
AWARNING: The clamp foot must remain clamped above the base of the saw whenever the
clamp is used. Always clamp the workpiece to the base of the saw-not to any other part of the
work area. Ensure the clamp foot is not clamped on the edge of the base of the saw.
SUPPORT FOR LONG PIECES
_&WARNING: To reduce the risk of serious personal injury, turn off the tool and discon-
nect it from the power source before attempting to move it, change accessories or make
any adjustments accept as written in laser adjustment instructions.
ALWAYS SUPPORT LONG PIECES.
Never use another person as a substitute for a table extension; as additional support for a
workpiece that is longer or wider than the basic miter saw table or to help feed, support or pull
the workpiece.
For best results, use the DW7080 extension work support to extend the table width of your saw.
Available from your dealer at extra cost. Support long workpieces using any convenient means
such as sawhorses or similar devices to keep the ends from dropping.
CUTTING PICTURE FRAMES, SHADOW BOXES AND OTHER FOUR-SIDED PROJECTS
To best understand how to make the items listed here, we suggest that you try a few simple
projects using scrap wood until you develop a "FEEl" for your saw.
Your saw is the perfect tool for mitering corners like the one shown in Figure 14. Sketch A in
Figure 13 shows a joint made by using the bevel adjustment to bevel the edges of the two boards
at 45° each to produce a 90° corner. For this joint the miter arm was locked in the zero position
and the bevel adjustment was locked at 45 °. The wood was positioned with the broad flat side
against the table and the narrow edge against the fence. The cut could also be made by mitering
right and left with the broad surface against the fence.
CUTTING TRIM MOLDING AND OTHER FRAMES
Sketch B in Figure 13 shows a joint made by setting the miter arm at 45° to miter the two boards
to form a 90 ° corner. To make this type of joint, set the bevel adjustment to zero and the miter
arm to 45°. Once again, position the wood with the broad flat side on the table and the narrow
edge against the fence.
The two sketches in Figure 13 are for four side objects only.
As the number of sides changes, so do the miter and bevel angles. The chart below gives the
proper angles for a variety of shapes.
- EXAMPLES -
NO. SIDES ANGLE MITER OR BEVEL
4 45 °
5 36 °
6 30 °
7 25.7 °
8 22.5 °
9 20 °
10 18°
(The chart assumes that all sides are of equal length.) For a shape that is not shown in the chart,
use the following formula. 180 ° divided by the number of sides equals the miter (if the material
is cut vertically) or bevel angle (if the material is cut laying flat).
CUTTING COMPOUND MITERS
A compound miter is a cut made using a miter angle and a bevel angle at the same time.
This is the type of cut used to make frames or boxes with slanting sides like the one shown in
Figure 15.
NOTE: If the cutting angle varies from cut to cut, check that the bevel clamp knob and the miter
lock knob are securely tightened. These knobs must be tightened after making any changes in
bevel or miter.
The chart (Table 1) will assist you in selecting the proper bevel and miter settings for common
compound miter cuts. To use the chart, select the desired angle "A" (Figure 15) of your project
and locate that angle on the appropriate arc in the chart. From that point follow the chart straight
down to find the correct bevel angle and straight across to find the correct miter angle.
Set your saw to the prescribed angles and make a few trial cuts. Practice fitting the cut pieces
together until you develop a feel for this procedure and feel comfortable with it.
Example: To make a four-sided box with 26 ° exterior angles (Angle A, Figure 15), use the upper
right arc. Find 26° on the arc scale. Follow the horizontal intersecting line to either side to get
miter angle setting on saw (42°). Likewise, follow the vertical intersecting line to the top or bottom
to get the bevel angle setting on the saw (18°). Always try cuts on a few scrap pieces of wood to
verify settings on saw.

CUTTING BASE MOLDING
ALWAYS MAKE A DRY RUN WITHOUT POWER BEFORE MAKING ANY CUTS.
Straight 90° cuts:
Position the wood against the fence and hold it in place as shown in Figure 16. Turn on the
saw, allow the blade to reach full speed and lower the arm smoothly through the cut.

Your miter saw is better suited to the task of cutting crown molding than any tool made. In order
to fit properly, crown molding must be compound mitered with extreme accuracy.
The two flat surfaces on a given piece of crown molding are at angles that, when added together,
equal exactly 90°. Most, but not all, crown molding has a top rear angle (the section that fits
flat against the ceiling) of 52° and a bottom rear angle (the part that fits flat against the wall)
of 38°.
Your miter saw has special pre-set miter latch points at 31.62 ° left and right for cutting crown
molding at the proper angle and bevel stop pawls at 33.85 ° left and right. There is also a mark
on the bevel scale at 33.85 °.
The chart below gives the proper settings for cutting crown molding. (The numbers for the
miter and bevel settings are very precise and are not easy to accurately set on your saw.)
Since most rooms do not have angles of precisely 90°, you will have to fine tune your
settings anyway.
PRETESTING WITH SCRAP MATERIAL IS EXTREMELY IMPORTANT!

When setting bevel and miter angles for all compound miters, remember that:
The angles presented for crown moldings are very precise and difficult to set exactly. Since
they can easily shift slightly and very few rooms have exactly square corners, all settings
should be tested on scrap molding.
PRETESTING WITH SCRAP MATERIAL IS EXTREMELY IMPORTANT!
ALTERNATIVE METHOD FOR CUTTING CROWN MOLDING
Place the molding on the table at an angle between the fence and the saw table, as shown
in Figure 17A. Use of the crown molding fence accessory (DW7084) is highly recommended
because of its degree of accuracy and convenience. The crown molding fence accessory is
available for purchase from your local dealer.
The advantage to cutting crown molding using this method is that no bevel cut is required.
Minute changes in the miter angle can be made without affecting the bevel angle. This way,
when corners other than 90 ° are encountered, the saw can be quickly and easily adjusted for
them. Use the crown molding fence accessory to maintain the angle at which the molding will
be on the wall.
INSTRUCTIONS FOR CUTTING CROWN MOLDING ANGLED BETWEEN THE FENCE
AND BASE OF THE SAW FOR ALL CUTS:
1. Angle the molding so the bottom of the molding (part which goes against the wall when
installed) is against the fence and the top of the molding is resting on the base of the saw, as
shown in Figure 17A.
2. The angled '_flats"on the back of the

Special Cuts
NEVER MAKE ANY CUT UNLESS THE MATERIAL IS SECURED ON THE TABLE
AND AGAINST THE FENCE.
ALUMINUM CUTTING
ALWAYS USE THE APPROPRIATE SAW BLADE MADE ESPECIALLY FOR CUTTING
ALUMINUM. These are available at your local DEWALT retailer or DEWALT service center.
Certain workpieces, due to their size, shape or surface finish, may require the use of a clamp
or fixture to prevent movement during the cut. Position the material so that you will be cutting
the thinnest cross section, as shown in Figure 18. Figure 18A illustrates the wrong way to cut
these extrusions. Use a stick wax cutting lubricant when cutting aluminum. Apply the stick wax
directly to the saw blade before cutting. Never apply stick wax to a moving blade.
The wax, available at most hardware stores and industrial mill supply houses, provides proper
lubrication and keeps chips from adhering to the blade.
Be sure to properly secure workpiece.
Refer to Saw Blades under OptionalAccessories for correct saw blade.
BOWED MATERIAL
When cutting bowed material always position it as shown in Figure 19 and never like that
shown in Figure 19A. Positioning the material incorrectly will cause it to pinch the blade near the
completion of the cut.
CUTTING PLASTIC PIPE OR OTHER ROUND MATERIAL
Plastic pipe can be easily cut with your saw. It should be cut just like wood and CLAMPED OR
HELD FIRMLY TO THE FENCE TO KEEP IT FROM ROLLING. This is extremely important
when making angle cuts.
CUTTING LARGE MATERIAL
Occasionally you will encounter a piece of wood a little too large to fit beneath the blade guard.
If this occurs, simply place your right thumb on the upper side of the guard and roll the guard
up just enough to clear the workpiece, as shown in Figure 20. Avoid doing this as much as
possible, but if need be, the saw will operate properly and make the bigger cut. NEVER TIE,
TAPE, OR OTHERWISE HOLD THE GUARD OPEN WHEN OPERATING THIS SAW.
SPECIAL SET-UP FOR WIDE CROSSCUTS
Your saw can cut very wide [up to 10" (406 mm)] workpieces when a special set up is used. To
set the saw up for these workpieces, follow these steps:
1. Remove both left and right sliding fences from the saw and set aside. To remove them,
unscrew the fence knobs several turns and slide each fence outward. Adjust and lock the
miter control so that it is at 0° miter.
2. Make a platform using a piece of 1.5 inch (38 mm) thick particleboard or similar flat strong
1.5" (38 mm) thick wood to the dimensions: 10" x 24" (254 x 610 mm). The platform must be
flat otherwise the material could move during cutting and cause injury.
3. Mount the 10" x 24" (254 x 610 mm) platform to the saw using 4 three-inch (76 mm) long
wood screws through the holes in the base fence (Fig. 9). Four screws must be used to
properly secure the material. When the special set up is used, the platform will be cut into
two pieces. Ensure the screws are tightened properly otherwise material could loosen and
cause injury. Ensure the platform is firmly flat on the table, against the fence, and centered
evenly from left to right.
AWARNING: Ensure the saw is mounted firmly to a stable flat surface. Failure to do so could
cause the saw to be unstable and fall causing personal injury.
4. Place the workpiece to be cut on top of the platform mounted to the table. Ensure the
workpiece is firmly against the backfence (Fig. 9).
5. Secure the material before cutting. Cut slowly through the material. Failure to clamp securely
or cut slowly could result in the material coming loose and causing injury.
After several cuts are made at various miter angles other than 0°, the platform may weaken
and not properly support the work. Install a new, unused platform to the saw after presetting the
desired miter angle.
CAUTION: Continued use of a platform with several kerfs may cause loss of material control
and possible injury.
Removing and Replacing Belt
The belt is designed to last the life of the tool. However, abuse of the tool could cause the belt
to fail.
If the blade does not turn when the motor is running, the belt has failed. To inspect or replace the
belt, remove the belt cover screws. Remove the belt cover. Inspect the ribs of the belt for wear or
failure. Check belt tension by squeezing the belt as shown in Figure 21. The belt halves should
almost touch when squeezing firmly with the thumb and index finger.
To adjust the tension, loosen, but do not remove, the four Phillips head screws shown. Then
rotate the set screw on the top of the motor plate casting until the proper tension is achieved.
Tighten the four screws securely and replace the belt cover.
NOTE: Over tightening the belt will cause premature motor failure.
MAINTENANCE
DO NOT use lubricants or cleaners (particularly spray or aerosol) in the vicinity of the plastic
guard. The polycarbonate material used in the guard is subject to attack by certain chemicals.
1. All bearings are sealed. They are lubricated for life and need no further maintenance.
2. Periodically clean all dust and wood chips from around AND UNDER the base and the
rotary table. Even though slots are provided to allow debris to pass through, some dust will
accumulate.
3. The brushes are designed to give you several years of use. If they ever need replacement
follow the instructions or return the tool to the nearest service center for repair. Service
center locations are packed with your tool.
