5. DON’T USE IN DANGEROUS ENVIRON-
MENT. Don’t use power tools in damp or
wet locations, or expose them to rain.
Keep work area well lighted. Don’t use
tool in presence of flammable liquids or
gases.
6. KEEP CHILDREN AWAY. All visitors
should be kept safe distance from work
area.
7. MAKE WORKSHOP KID PROOF with pad-
locks, master switches, or by removing
starter keys.
8. DON’T FORCE TOOL. It will do the job bet-
ter and safer at the rate for which it was
designed.
9. USE RIGHT TOOL. Don’t force tool or
attachment to do a job for which it was not
designed.
10. WEAR PROPER APPAREL. Do not wear
loose clothing, gloves, neckties, rings,
bracelets, or other jewelry which may get
caught in moving parts. Nonslip footwear
is recommended. Wear protective hair
covering to contain long hair.
11. ALWAYS USE SAFETY GLASSES. Also
use face or dust mask if cutting operation
is dusty. Everyday eyeglasses only have
impact resistant lenses, they are NOT
safety glasses.
12. SECURE WORK. Use clamps or a vise to
hold work when practical. It’s safer than
using your hand and it frees both hands
to operate tool.
13. DON’T OVERREACH. Keep proper footing
and balance at all times.
14. MAINTAIN TOOLS WITH CARE. Keep tools
sharp and clean for best and safest perfor-
mance. Follow instructions for lubricating
and changing accessories.
15. DISCONNECT TOOLS before servicing;
when changing accessories such as
blades, bits, cutters, and the like.
16. REDUCE THE RISK OF UNINTENTIONAL
STARTING. Make sure switch is in off
position before plugging in.
17. USE RECOMMENDED ACCESSORIES.
Consult the owner’s manual for recom-
mended accessories. The use of improper
accessories may cause risk of injury to
persons.
18. NEVER STAND ON TOOL. Serious injury
could occur if the tool is tipped or if the
cutting tool is unintentionally contacted.
19. 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, mount-
ing, and any other conditions that may
affect its operation. A guard or other part
that is damaged should be properly
repaired or replaced.
20. DIRECTION OF FEED. Feed work into a
blade or cutter against the direction of
rotation of the blade or cutter only.
21. NEVER LEAVE TOOL RUNNING UNAT-
TENDED. TURN POWER OFF. Don’t leave
tool until it comes to a complete stop.
22. REPLACEMENT PARTS. When servicing
use only identical replacement parts.
23. POLARIZED PLUGS. To reduce the risk of
electric shock, this equipment 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 elec-
trician to install the proper outlet. Do not
change the plug in any way.

4
VOLTAGE WARNING: Before connecting the tool to a power source (receptacle, outlet,
etc.) be sure the voltage supplied is the same as that specified on the nameplate of the tool.
A power source with voltage greater than that specified for the tool can result in SERIOUS
INJURY to the user - as well as damage to the tool. If in doubt, DO NOT PLUG IN THE
TOOL. Using a power source with voltage less than the nameplate rating is harmful to the
motor.
USE PROPER EXTENSION CORD. Make sure your extension cord is in good condition.
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. Table 1 shows the correct size to use depending on cord length and
nameplate ampere rating. If in doubt, use the next heavier gage. The smaller the gage num-
ber, the heavier the cord.
ADDITIONAL SAFETY RULES USB037-2
DO NOT let comfort or familiarity with product (gained from
repeated use) replace strict adherence to miter saw safety rules.
If you use this tool unsafely or incorrectly, you can suffer seri-
ous personal injury.
1. Wear eye protection.
2. Keep hands out of path of saw blade.
Avoid contact with any coasting blade. It
can still cause severe injury.
3. Do not operate saw without guards in
place. Check blade guard for proper clos-
ing before each use. Do not operate saw if
blade guard does not move freely and
close instantly. Never clamp or tie the
blade guard into the open position.
4. Do not perform any operation freehand.
The workpiece must be secured firmly
against the turn base and guide fence with
a vise during all operations. Never use
your hand to secure the workpiece.
5. Never reach around saw blade.
6. Turn off tool and wait for saw blade to
stop before moving workpiece or chang-
ing settings.
7. Unplug tool before changing blade or ser-
vicing.
8. Always secure all moving portions before
carrying the tool.

9. Do not use the tool in the presence of
flammable liquids or gases.
10. Check the blade carefully for cracks or
damage before operation. Replace
cracked or damaged blade immediately.
Gum and wood pitch hardened on blades
slows saw and increases potential for
kickback. Keep blade clean by first remov-
ing it from tool, then cleaning it with gum
and pitch remover, hot water or kerosene.
Never use gasoline to clean blade.
11. Use only flanges specified for this tool.
12. Be careful not to damage the arbor,
flanges (especially the installing surface)
or bolt. Damage to these parts could
result in blade breakage.
13. Make sure that the turn base is properly
secured so it will not move during opera-
tion. Use the holes in the base to fasten
the saw to a stable work platform or
bench. NEVER use tool where operator
positioning would be awkward.
14. For your safety, remove the chips, small
pieces, etc. from the table top before oper-
ation.
15. Avoid cutting nails. Inspect for and
remove all nails from the workpiece
before operation.
16. Make sure the shaft lock is released
before the switch is turned on.
17. Be sure that the blade does not contact
the turn base in the lowest position.
18. Hold the handle firmly. Be aware that the
saw moves up or down slightly during
start-up and stopping.
19. Make sure the blade is not contacting the
workpiece before the switch is turned on.
20. Before using the tool on an actual work-
piece, let it run for a while. Watch for
vibration or wobbling that could indicate
poor installation or a poorly balanced
blade.
21. Wait until the blade attains full speed
before cutting.
22. Stop operation immediately if you notice
anything abnormal.
23. Do not attempt to lock the trigger in the on
position.
24. Be alert at all times, especially during
repetitive, monotonous operations. Do
not be lulled into a false sense of security.
Blades are extremely unforgiving.
25. Always use accessories recommended in
this manual. Use of improper accessories
such as abrasive wheels may cause an
injury.
26. NEVER hold workpiece on right side of
blade with left hand or vice versa. This is
called cross-armed cutting and exposes
user to risk of SERIOUS PERSONAL
INJURY as shown in the figure. ALWAYS
use vise to secure workpiece.
27. Do not abuse cord. Never yank cord to
disconnect it from the receptacle. Keep
cord away from heat, oil, water and sharp
objects.
28. NEVER stack workpieces on the table top
to speed cutting operations. Cut only one
piece at a time.
29. Some material contains chemicals which
may be toxic. Take caution to prevent dust
inhalation and skin contact. Follow mate-
rial supplier safety data.

INSTALLATION Bench mounting
When the tool is shipped, the handle is locked in the lowered
position by the stopper pin. Release the stopper pin by lower-
ing the handle slightly and pulling the stopper pin.
This tool should be bolted with four bolts to a level and stable
surface using the bolt holes provided in the tool’s base. This
will help prevent tipping and possible injury.
FUNCTIONAL
DESCRIPTION CAUTION:
• Always be sure that the tool is switched off and
unplugged before adjusting or checking function on the
tool.
Blade guard
When lowering the handle, the blade guard rises automati-
cally. The guard is spring loaded so it returns to its original
position when the cut is completed and the handle is raised.
NEVER DEFEAT OR REMOVE THE BLADE GUARD OR
THE SPRING WHICH ATTACHES TO THE GUARD.
In the interest of your personal safety, always maintain the
blade guard in good condition. Any irregular operation of the
blade guard should be corrected immediately. Check to
assure spring loaded return action of guard. NEVER USE
THE TOOL IF THE BLADE GUARD OR SPRING ARE DAM-
AGED, FAULTY OR REMOVED. DOING SO IS HIGHLY
DANGEROUS AND CAN CAUSE SERIOUS PERSONAL
INJURY.

If the see-through blade guard becomes dirty, or sawdust
adheres to it in such a way that the blade is no longer easily
visible, unplug the saw and clean the guard carefully with a
damp cloth. Do not use solvents or any petroleum-based
cleaners on the plastic guard.
If the blade guard is especially dirty and vision through the
guard is impaired, use the supplied socket wrench to loosen
the hex bolt holding the center cover. Loosen the hex bolt by
turning it counterclockwise and raise the blade guard and
center cover. With the blade guard so positioned, cleaning
can be more completely and efficiently accomplished. When
cleaning is complete, reverse procedure above and secure
bolt. Do not remove spring holding blade guard. If guard
becomes discolored through age or UV light exposure, con-
tact a Makita service center for a new guard. DO NOT
DEFEAT OR REMOVE GUARD.
Positioning kerf board
This tool is provided with the kerf boards in the turn base to
minimize tearing on the exit side of a cut. The kerf boards are
factory adjusted so that the saw blade does not contact the
kerf boards. Before use, adjust the kerf boards as follows:
First, unplug the tool. Loosen all the screws (2 each on left
and right) securing the kerf boards. Re-tighten them only to
the extent that the kerf boards can still be easily moved by
hand. Lower the handle fully and push in the stopper pin to
lock the handle in the lowered position. Adjust the kerf
boards so that the kerf boards just contact the sides of the
blade teeth. Tighten all the screws (do not tighten firmly).
After adjusting the kerf boards, release the stopper pin and
raise the handle. Then tighten all the screws securely.

CAUTION:
•When cutting long workpieces, use supports that are as
high as the top surface level of the turn base. Do not rely
solely on the vertical vise and/or horizontal vise to
secure the workpiece.
Thin material tends to sag. Support workpiece over its
entire length to avoid blade pinch and possible
KICKBACK.
Sub-fence
This tool is equipped with the sub-fence. It should be posi-
tioned as shown in the figure.
CAUTION:
•When performing left bevel cuts, flip the fence over to the
left position as shown in the figure. Otherwise, it will
contact the blade or a part of the tool, causing possible
serious injury to the operator.
Vertical vise
The vertical vise can be installed in two positions on either
the left or right side of the guide fence or the holder assembly
(optional accessory). Insert the vise rod into the hole in the
guide fence or the holder assembly and tighten the screw to
secure the vise rod.
Position the vise arm according to the thickness and shape
of the workpiece and secure the vise arm by tightening the
screw. If the screw to secure the vise arm contacts the guide
fence, install the screw on the opposite side of vise arm.
Make sure that no part of the tool contacts the vise when
lowering the handle all the way. If some part contacts the

base. Position the workpiece at the desired cutting position
and secure it firmly by tightening the vise knob.
CAUTION:
•The workpiece must be secured firmly against the turn
base and guide fence with the vise during all operations.
Horizontal vise (optional accessory)
The horizontal vise can be installed in two positions on either
the left or right side of the base. When performing 15°or
greater miter cuts, install the horizontal vise on the side
opposite the direction in which the turn base is to be turned.
By flipping the vise nut to the left, the vise is released, and
rapidly moves in and out. To grip the workpiece, push the
vise knob forward until the vise plate contacts the workpiece
and flip the vise nut to the right. Then turn the vise knob
clockwise to secure the workpiece.
The maximum width of workpiece which can be secured by
the horizontal vise is 200 mm (7 - 7/8”).
CAUTION:
•Always rotate the vise nut to the right fully when securing
the workpiece. Failure to do so may result in insufficient
securing of the workpiece. This could cause the
workpiece to be thrown, cause damage to the blade or
cause the loss of control, which can result in
PERSONAL INJURY.
Holders and holder assembly
(optional accessories)
The holders and the holder assembly can be installed on
either side as a convenient means of supporting workpieces
horizontally. Install them as shown in the figure. Then tighten
the screws firmly to secure the holders and the holder

When cutting long workpieces, use the holder-rod assembly
(optional accessory). It consists of two holder assemblies
and two rods 12.
CAUTION:
•Always support long workpieces level with the top
surface of the turn base for accurate cuts and to prevent
dangerous loss of control of the tool.
OPERATION CAUTION:
•Before use, be sure to release the handle from the
lowered position by pulling the stopper pin.
•Make sure the blade is not contacting the workpiece, etc.
before the switch is turned on.
•Do not apply excessive pressure on the handle when
cutting. Too much force may result in overload of the
motor and/or decreased cutting efficiency. Push down
handle with only as much force as is necessary for
smooth cutting and without significant decrease in blade
speed.
•Gently press down the handle to perform the cut. If the
handle is pressed down with force or if lateral force is
applied, the blade will vibrate and leave a mark (saw
mark) in the workpiece and the precision of the cut will
be impaired.
1. Press cutting
Secure the workpiece with the vise. Switch on the tool
without the blade making any contact and wait until the
blade attains full speed before lowering. Then gently
lower the handle to the fully lowered position to cut the
workpiece. When the cut is completed, switch off the tool
and WAIT UNTIL THE BLADE HAS COME TO A COM-
PLETE STOP before returning the blade to its fully ele-
vated position.
2. Miter cutting
Refer to the previously covered “Adjusting the miter
angle”.

3. Bevel cut
Loosen the lever and tilt the saw blade to set the bevel
angle (Refer to the previously covered “Adjusting the
bevel angle”). Be sure to retighten the lever firmly to
secure the selected bevel angle safely. Secure the work-
piece with a vise. Switch on the tool without the blade
making any contact and wait until the blade attains full
speed. Then gently lower the handle to the fully lowered
position while applying pressure in parallel with the
blade. When the cut is completed, switch off the tool and
WAIT UNTIL THE BLADE HAS COME TO A COM-
PLETE STOP before returning the blade to its fully ele-
vated position.
CAUTION:
•Always be sure that the blade will move down to bevel
direction during a bevel cut. Keep hands out of path of
saw blade.
•During a bevel cut, it may create a condition whereby the
piece cut off will come to rest against the side of the
blade. If the blade is raised while the blade is still
rotating, this piece may be caught by the blade, causing
fragments to be scattered which is dangerous. The blade
should be raised ONLY after the blade has come to a
complete stop.
•When pressing the handle down, apply pressure parallel
to the blade. If the pressure is not parallel to the blade
during a cut, the angle of the blade might be shifted and
the precision of the cut will be impaired.
•Always set the sub-fence to the left position when
performing left bevel cuts.
4. Compound cutting
Compound cutting is the process in which a bevel angle
is made at the same time in which a miter angle is being
cut on a workpiece. Compound cutting can be performed
at angle shown in the table.
When performing compound cutting, refer to “Press cut-
ting”, “Miter cutting”and “Bevel cut”explanations.

5. Cutting crown and cove moldings
Crown and cove moldings can be cut on a compound
miter saw with the moldings laid flat on the turn base.
There are two common types of crown moldings and one
type of cove moldings; 52/38°wall angle crown molding,
45°wall angle crown molding and 45°wall angle cove
molding. See illustrations.
There are crown and cove molding joints which are
made to fit “Inside” 90°corners ((1) and (2) in Fig. A) and
“Outside” 90°corners ((3) and (4) in Fig. A).
Measuring
Measure the wall length and adjust workpiece on table to
cut wall contact edge to desired length. Always make
sure that cut workpiece length at the back of the work-
piece is the same as wall length. Adjust cut length for
angle of cut. Always use several pieces for test cuts to
check the saw angles.
When cutting crown and cove moldings, set the bevel
angle and miter angle as indicated in the table (A) and
position the moldings on the top surface of the saw base
as indicated in the table (B).
