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 in-
sulation. 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 product 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 replace-
ment parts when servicing.
ELECTRICAL CONNECTION
This tool has a precision-built electric motor. It should be
connected to a power supply that is 120 V, AC only (normal
household current), 60 Hz. 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 the 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 product 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 product, use an extension
cord that is designed for outside use. This type of cord is
designated with “WA” or “W” 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 dam-
aged replace immediately. Never use tool with a
damaged cord since touching the damaged area
could cause electrical shock resulting in serious
injury.

MOUNTING HOLES
See Figure 9.
WARNING:
Before starting any cutting operation, clamp or bolt
your miter saw to a workbench or an approved mi-
ter saw stand. If a miter saw stand is used, read op-
erator’s manual and follow the instructions for the
miter saw stand. Never operate your miter saw on
the floor or in a crouched position. Failure to heed
this warning can result in serious personal injury.
The compound miter saw should be mounted to a firm sup-
porting surface such as a workbench, mounting board, or
miter saw stand. Four bolt holes have been provided in the
saw base for this purpose. Each of the four mounting holes
should be bolted securely using 5/16 in. machine bolts, lock
washers, and hex nuts (not included). Bolts should be of suf-
ficient length to accommodate the saw base, lock washers,
hex nuts, and the thickness of the workbench. Tighten all
four bolts securely.
The hole pattern for mounting to a workbench is shown in
figure 9. Carefully check the workbench after mounting to
make sure that no movement can occur during use. If any
tipping, sliding, or walking is noted, secure the workbench
to the floor before operating.
MITER LOCK KNOB
See Figure 10.
To install the miter lock knob, place the threaded stud on
the end of the miter lock knob into the threaded hole in the
control arm. Turn clockwise to tighten.
DUST BAG
See Figure 11.
A dust bag is provided for use on the miter saw. It fits over the
exhaust port 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 exhaust port. Release the clips. The metal ring in
the bag should lock in between the grooves on the exhaust
port. 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 as-
sembly. 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

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:
Place the shaft of the work clamp in either hole on the
miter table base.
Rotate the knob on the work clamp to move it in or out
as needed.
TO INSTALL THE BLADE
See Figure 13.
WARNING:
A 10 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.
Unplug the saw.
Raise saw arm.
Rotate lower blade guard up and loosen blade bolt cover
screw. Slide blade bolt cover toward upper blade guard
to expose the blade bolt.
Depress the spindle lock button and rotate the blade bolt
until the spindle locks.
Using the wrench provided, loosen and remove the blade
bolt.
NOTE: The blade bolt has left hand threads. Turn blade
bolt clockwise to loosen.
Remove the outer blade washer. Do not remove the inner
blade washer.
Wipe a drop of oil onto the inner blade washer and the
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.
Fit saw blade inside upper blade guard and onto spindle.
The blade teeth point downward at the front of saw as
shown in figure 13.
Replace the outer blade washer. The double “D” flats on
the blade washers align with the flats on the spindle.
Depress spindle lock button and replace blade bolt.
NOTE: The blade bolt has left hand threads. Turn blade
bolt counterclockwise to tighten.
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.
Tighten blade bolt securely.
Replace blade bolt cover and tighten blade bolt cover-
screw securely.
Lower the blade guard.
Raise and lower the saw arm to ensure lower blade guard
functions correctly.

WARNING:
Make sure the spindle lock button is not engaged
before reconnecting saw into power source.
Never engage spindle lock button when blade is
rotating.
DANGER:
Laser radiation. Avoid direct eye contact with light
source.
WARNING:
Use of controls, adjustments, or performance of
procedures other than those specified here can
result in hazardous radiation exposure.
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°bevel,
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, loosen the bevel lock knob and set saw arm at 48°.
Tighten the bevel lock knob. (It may be necessary to adjust
or remove the sliding miter fence to insure proper clearance
prior to making the cut.) 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 48°.
WARNING:
The laser guide is powered by the AC power sup-
plied to the saw. User must lock out the trigger
switch prior to aligning or performing any mainte-
nance on the laser. Failure to lock out the trigger
switch could lead to inadvertent actuation of the mi-
ter saw which could result in serious personal injury.
ALIGNING THE LASER GUIDE LINE
See Figure 14.
Lock out the trigger switch by installing a long shackled
padlock (not included) up to 9/32 in. diameter. Plug the saw
into the power source. Draw a line on the workpiece. When
the laser guide switch is turned on it will generate a red line
on the work surface. This line will let you see your mark and
the laser guide line at the same time, and will assist you in
lining up the mark for more accurate cutting of the workpiece.
ASSEMBLY
Fig. 14
Align the laser line and the mark with the saw arm at the
uppermost position. Once both lines are in alignment, do
not move the workpiece.
Remove the padlock. Make several practice cuts on different
styles and thickness of material. Repeat the steps above as
necessary.
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.

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:
Always wear eye protection with side shields
marked to comply with ANSI Z87.1. Failure to do
so could result in objects being thrown into your
eyes, resulting in possible serious injury.
WARNING:
Do not use any attachments or accessories not
recommended by the manufacturer of this tool.
The use of attachments or accessories not recom-
mended 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.
Bevel cutting and compound cutting.
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 the place of
purchase of your new Ridgid miter saw.
WARNING:
Before starting any cutting operation, clamp or bolt
your miter saw to a workbench or leg stand. 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:
To avoid serious personal injury, always tighten
the miter lock knob and bevel lock knob securely
before making a cut. Failure to do so could result
in movement of the control arm or miter table while
making a cut.
OPERATION
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 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. Failure to heed this warning can also result in
serious personal injury.
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 pos-
sible serious personal injury.
WARNING:
NEVER move the workpiece or make adjustment to
any cutting angle while the saw is running and the
blade is rotating. Any slip can result in contact with
the blade causing serious personal injury.
