GENERAL SAFETY RULES
n
Avoid accidental starting. Be sure switch is off before
plugging in. Carrying tools with your finger on the switch
or plugging in tools that have the switch on invites acci-
dents.
WARNING:
Read and understand all instructions. Failure to
follow all instructions listed below, may result in
electric shock, fire and/or serious personal injury.
n 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.
SAVE THESE INSTRUCTIONS
WORK AREA
n Do not overreach. Keep proper footing and balance
at all times. Proper footing and balance enables better
control of the tool in unexpected situations.
n Keep your work area clean and well lit. Cluttered
n Use safety equipment. Always wear eye protection.
Dust mask, nonskid safety shoes, hard hat, or hearing
protection must be used for appropriate conditions.
benches and dark areas invite accidents.
n 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.
n Do not wear loose clothing or jewelry. Contain long
hair. Loose clothes, jewelry, or long hair can be drawn
into air vents.
n Keep bystanders, children, and visitors away while
operating a power tool. Distractions can cause you to
lose control.
n Do not use on a ladder or unstable support. Stable
footing on a solid surface enables better control of the
tool in unexpected situations.
ELECTRICAL SAFETY
TOOL USE AND CARE
n Double insulated tools are equipped with 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 a
polarized outlet. Do not change the plug in any way.
n 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.
n Do not force tool. Use the correct tool for your appli-
cation. The correct tool will do the job better and safer
at the rate for which it is designed.
Double insulation
eliminates the need for the three-
wire grounded power cord and grounded power supply
system.
n Do not use tool if switch does not turn it on or off.
Any tool that cannot be controlled with the switch is
dangerous and must be repaired.
n Avoid body contact with grounded surfaces such as
pipes, radiators, ranges, and refrigerators. There is an
increased risk of electric shock if your body is grounded.
n Disconnect the plug from power source before mak-
ing any adjustments, changing accessories, or storing
the tool. Such preventive safety measures reduce the
risk of starting the tool accidentally.
n Don’t expose power tools to rain or wet conditions.
Water entering a power tool will increase the risk of elec-
tric shock.
n Store idle tools out of the reach of children and other
untrained persons. Tools are dangerous in the hands of
untrained users.
n Do not abuse the cord. Never use the cord to carry the
tools or pull the plug from an outlet. Keep cord away
from heat, oil, sharp edges, or moving parts. Replace
damaged cords immediately. Damaged cords increase
the risk of electric shock.
n 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.
n
When operating a power tool outside, use an outdoor ex-
tension cord marked “W-A” or “W”. These cords are rated
for outdoor use and reduce the risk of electric shock.
n 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.
PERSONAL SAFETY
n 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.
n Use only accessories that are recommended by the
manufacturer for your model. Accessories that may be
suitable for one tool, may become hazardous when used
on another tool.
n 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.
n Keep the tool and its handle dry, clean and free from
oil and grease. Always use a clean cloth when clean-
ing. Never use brake fluids, gasoline, petroleum-based
products, or any strong solvents to clean your tool. Fol-
lowing this rule will reduce the risk of loss of control and
deterioration of the enclosure plastic.

GENERAL SAFETY RULES
nWhen servicing a tool, use only identical replacement
parts. Follow instructions in the Maintenance section
of this manual. Use of unauthorized parts or failure to fol-
low Maintenance Instructions may create a risk of shock
or injury.
SERVICE
nTool service must be performed only by qualified re-
pair personnel. Service or maintenance performed by
unqualified personnel may result in a risk of injury.
SPECIFIC SAFETY RULES
n DANGER! Keep hands away from cutting area and
blade. Keep your second hand on the auxiliary handle,
or motor housing. If both hands are holding the saw,
they cannot be cut by the blade.
n Always use blades with correct size and shape (dia-
mond vs. round) arbor holes. Blades that do not match
the mounting hardware of the saw will run eccentrically,
causing loss of control.
n Keep your body positioned to either side of the saw
blade, but not in line with the saw blade. Kickback
could cause the saw to jump backwards. (See “Causes
and Operator Prevention of Kickback.”)
n Never use damaged or incorrect blade washers or
bolts. The blade washers and bolts were specially de-
signed for the saw for optimum performance and safety
of operation.
n Do not reach underneath the work. The guard can not

protect you from the blade below the work.
KICKBACK
n Check lower guard for proper closing before each
use. Do not operate saw if lower guard does not
move freely and close instantly. Never clamp or tie
the lower guard into the open position. If saw is ac-
cidentally dropped, lower guard may be bent. Raise the
lower guard with the Retracting Handle and make sure it
moves freely and does not touch the blade or any other
part, in all angles and depths of cut.
Kickback is a sudden reaction to a pinched, bound, or mis-
aligned saw blade, causing an uncontrolled saw to lift up
and out of the workpiece toward the operator.
When the blade is pinched or bound tightly by the kerf clos-
ing down, the blade stalls and the motor reaction drives the
unit rapidly back toward the operator.
If the blade becomes twisted or misaligned in the cut, the
teeth at the back edge of the blade can dig into the top
surface of the wood causing the blade to climb out of the
kerf and jump back toward the operator.
n Check the operation and condition of the lower guard
spring. If the guard and the spring are not operating
properly, they must be serviced before use. Lower
guard may operate sluggishly due to damaged parts,
gummy deposits, or a buildup of debris.
Kickback is the result of tool misuse and/or incorrect operat-
ing procedures or conditions and can be avoided by taking
proper precautions, as given below:
n Lower guard should be retracted manually only for
special cuts, such as “Pocket Cuts” and “Compound
Cuts.” Raise lower guard by retracting handle. As
soon as blade enters the material, lower guard must
be released. For all other sawing, the lower guard should
operate automatically.
n Maintain a firm grip with both hands on the saw and
position your body and arm to allow you to resist
KICKBACK forces. KICKBACK forces can be controlled
by the operator, if proper precautions are taken.
n When blade is binding, or when interrupting a cut
for any reason, release the trigger and hold the saw
motionless in the material until the blade comes to a
complete stop. Never attempt to remove the saw from
the work or pull the saw backward while the blade is
in motion, or KICKBACK may occur. Investigate and
take corrective actions to eliminate the cause of blade
binding.
n Always observe that the lower guard is covering the
blade before placing saw down on bench or floor. An
unprotected, coasting blade will cause the saw to walk
backwards, cutting whatever is in its path. Be aware of
the time it takes for the blade to stop after switch is re-
leased.
n NEVER hold piece being cut in your hands or across
your leg. It is important to support the work properly to
minimize body exposure, blade binding, or loss of con-
trol.
n When restarting a saw in the workpiece, center the
saw blade in the kerf and check that saw teeth are
not engaged into the material. If saw blade is binding,
it may walk up or KICKBACK from the workpiece as the
saw is restarted.
n Hold tool by insulated gripping surfaces when per-
forming an operation where the cutting tool may
contact hidden wiring or its own cord. Contact with a
“live” wire will also make exposed metal parts of the tool
“live” and shock the operator.
n Support large panels to minimize the risk of blade
pinching and KICKBACK. Large panels tend to sag
under their own weight. Supports must be placed under
the panel on both sides, near the line of cut and near the
edge of the panel.
n When ripping always use a rip fence or straight edge
guide. This improves the accuracy of the cut and reduces
the chance for blade binding.

be tight and secure before making cut. If blade ad-
justment shifts while cutting, it may cause binding and
KICKBACK.
When using an extension cord, be sure to use one
heavy enough to carry the current your product will
draw. A wire gage size (A.W.G.) of at least 12 is rec-
ommended for an extension cord 50 feet or less in
length. A cord exceeding 50 feet is not recommended.
If in doubt, use the next heavier gage. The smaller the
gage number, the heavier the cord. An undersized cord
will cause a drop in line voltage resulting in loss of power
and overheating.
n Use extra caution when making a “Pocket Cut” into
existing walls or other blind areas. The protruding blade
may cut objects that can cause KICKBACK.
ADDITIONAL SAFETY RULES
nInspect tool cords periodically and, if damaged, have
repaired at your nearest Authorized Service Center.
Constantly stay aware of cord location. Following this
rule will reduce the risk of electric shock or fire.
nInspect for and remove all nails from lumber before
using this tool. Following this rule will reduce the risk of
serious personal injury.
nCheck 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

them to instruct others who may use this tool. If you loan
someone this tool, loan them these instructions also.
WARNING:
Some dust created by power sanding, sawing, grinding, drilling, and other construction activities contains chemicals
known to cause cancer, birth defects or other reproductive harm. Some examples of these chemicals are:
• lead from lead-based paints,
• crystalline silica from bricks and cement and other masonry products, and
• arsenic and chromium from chemically-treated lumber.
Your risk from these exposures varies, depending on how often you do this type of work. To reduce your exposure
to these chemicals: work in a well ventilated area, and work with approved safety equipment, such as those dust
masks that are specially designed to filter out microscopic particles.

ELECTRICAL
When working outdoors with a tool, use an extension cord
that is designed for outside use. This type of cord is desig-
nated with “WA” on the cord’s jacket.
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 protect-
ing insulation. Double insulated tools do not need to be
grounded.
Before using any extension cord, inspect it for loose or ex-
posed wires and cut or worn insulation.

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 sug-
gest you return the tool to your nearest authorized service
center for repair. Always use original factory replacement
parts when servicing.
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.
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.
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.
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 un-
dersized 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.

OPERATION
WARNING:
Do not allow familiarity with the tool to make you
careless. Remember that a careless fraction of a
second is sufficient to inflict severe injury.
APPLICATIONS
You may use this saw for the following purposes:
n Cutting all types of wood products (lumber, plywood,
paneling)
NOTE: The use of abrasive cut-off wheels is not recom-
mended for this saw.
LOWER
BLADE GUARD
WARNING:
Fig. 4
The use of this saw on materials not listed may
damage the saw and its guards, and may cause
serious personal injury.
WARNING:
To avoid possible serious injury, never use saw when
guard is not operating correctly. Check the guard for
correct operation before each use. The guard is op-
erating correctly when it moves freely, and instantly
returns to the closed position. If you drop the saw,
check the lower blade guard and bumper for dam-
age at all depth settings before reuse.
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.
If at any time the lower blade guard does not snap closed,
unplug the saw from the power supply. Exercise the lower
guard by moving it rapidly back and forth from the full open
position to the closed position several times. Normally this
will restore the guard to its normal operating condition. If
it does not correct a slow or sluggish closing lower guard,
do not use the saw. Take it to an authorized factory service
center for repair.
SAW BLADES
The best of saw blades will not cut efficiently if they are not
kept clean, sharp, and properly set. Using a dull blade will
place a heavy load on the saw and increase the danger of
kickback. Keep extra blades on hand, so that sharp blades
are always available.
Gum and wood pitch hardened on blades will slow the saw
down. Remove saw blade from the saw and use gum and
pitch remover, hot water, or kerosene to remove these ac-
cumulations. DO NOT USE GASOLINE.
BLADE GUARD SYSTEM
See Figure 4.
The lower blade guard attached to your saw is there for
your protection and safety. Do not alter it for any reason.
If it becomes damaged, do not operate the saw until you
have the guard repaired or replaced. Always leave guard in
operating position when using the saw.
DANGER:
When sawing through work, lower blade guard does
not cover blade on the underside of work. Since
blade is exposed on underside of work, keep hands
and fingers away from cutting area. Any part of your
body coming in contact with moving blade will result
in serious injury.

OPERATION
KICKBACK
See Figures 5, 6, 7, and 8.
Kickback occurs when the blade stalls rapidly and the saw
is driven back towards you. Blade stalling is caused by any
action which pinches the blade in the wood. See Figure 5.
DANGER:
Release switch immediately if blade binds or saw
stalls. Kickback could cause you to lose control of
the saw. Loss of control can lead to serious injury.
Fig. 5
To guard against kickback, avoid dangerous practices such
as the following.
n Setting blade depth incorrectly.
n Sawing into knots or nails in workpiece.
n Twisting the blade while making a cut.
n Making a cut with a dull, gummed up, or improperly set
blade.
n Supporting the workpiece incorrectly. See Figure 6.
n Forcing a cut.
n Cutting warped or wet lumber.
n Operating the tool incorrectly or misusing the tool.
To lessen the chance of kickback, follow these safety prac-
tices.
Fig. 6
n Do not cut warped or wet lumber.
n Keep the blade at the correct depth setting. The depth
setting should not exceed 1/4 in. (6.4 mm) below the
material being cut. See Figure 7.
n Inspect the workpiece for knots or nails before cutting.
Never saw into a knot or nail.
n Make straight cuts. Always use a straight edge guide
when rip cutting. This helps prevent twisting the blade.
n Use clean, sharp, and properly set blades. Never make
cuts with dull blades.
n Support the workpiece properly before beginning a cut
as shown in figure 8.
Fig. 7
n Use steady, even pressure when making a cut. Never
force a cut.
n Hold the saw firmly with both hands and keep your body
in a balanced position so as to resist the forces if kickback
should occur.
WARNING:
When using the saw, always stay alert and exercise
control. Do not remove the saw from the workpiece
while the blade is moving.

To stop the saw: Release the switch trigger.
After you release the switch trigger, allow the blade to come
to a complete stop. Do not remove the saw from the work-
piece while the blade is moving.
ADJUSTING BLADE DEPTH
See Figure 10.
Fig. 9
Always keep correct blade depth setting. The correct blade
depth setting for all cuts should not exceed 1/4 in. (6.35
mm) below the material being cut. More blade depth will
increase the chance of kickback and cause the cut to be
rough. For more depth of cut accuracy, a scale is located
on the elevation bracket.
ELEVATION
BRACKET
n Unplug the saw.
n Pull depth adjustment lever upward to release. The depth
adjustment lever is located between the guard and handle
of the saw.
n Determine the desired depth of cut. See Figure 7.
n Hold base flat against the workpiece and raise or lower
saw until the desired depth is reached.
n Tighten the depth adjustment lever to secure the

OPERATION
OPERATING THE SAW
See Figures 11, 12, and 13.
It is important to understand the correct method for operat-
ing the saw. Refer to the figures in this section to learn the
correct and incorrect ways for handling the saw.
WARNING:
To make sawing easier and safer, always maintain
proper control of the saw. Loss of control could
cause an accident resulting in possible serious
injury.
DANGER:
Fig. 11
When lifting the saw from the workpiece, the blade
is exposed on the underside of the saw until the
lower blade guard closes. Make sure the lower blade
guard is closed before setting the saw down.
To make the best possible cut, follow these helpful hints.
n Hold the saw firmly with both hands.
n Avoid placing your hand on the workpiece while making
a cut. See Figure 11.
LINE OF
CUT
n Support the workpiece so that the cut is always on your
right.
n Support the workpiece near the cut.
n Clamp the workpiece securely so that the workpiece will
not move during the cut. See Figure 12.
n Avoid placing the saw on the part of the workpiece that
will fall off when the cut is made. See Figure 13.
Fig. 12
n Place the workpiece with the “good” side down.
n Draw a guideline along the desired line of cut before
beginning the cut.
n Keep the cord away from the cutting area. Always place
the cord to prevent it from hanging up on the workpiece
while making a cut.
DANGER:
If the cord hangs up on the workpiece during a cut,
release the switch trigger immediately. Unplug the
saw and reposition the cord to prevent it from hang-
ing up again.
DANGER:
Using a saw with a damaged cord could result in
serious injury or death. If the cord has been dam-
aged, have it replaced before using the saw again.

OPERATION
CROSS CUTTING
See Figure 14.
When making a cross cut, align the line of cut with the full
length kerf indicator on the base as shown in figure 14.
Since blade thicknesses vary, always make a trial cut in scrap
material along a guideline to determine how much, if any, you
must offset the guideline to produce an accurate cut.
NOTE: The distance from the line of cut to the guideline is
the amount you should offset the guide.

MAINTENANCE
Electric tools used on fiberglass material, wallboard, spack-
ling compounds, or plaster are subject to accelerated wear
and possible premature failure because the fiberglass chips
and grindings are highly abrasive to bearings, brushes, com-
mutators, etc. Consequently, we do not recommended using
this tool for extended work on these types of materials. How-
ever, if you do work with any of these materials, it is extremely
important to clean the tool using compressed air.
WARNING:
When servicing use only identical RIDGID® replace-
ment parts. Use of any other parts may create a
hazard or cause product damage.
Do not abuse power tools. Abusive practices can damage
tool as well as workpiece.
WARNING:
WARNING:
The tool should never be connected to a power
supply when you are assembling parts, making
adjustments, cleaning, performing maintenance,
or when the tool is not in use. Disconnecting the

MAINTENANCE
LUBRICATION
See Figure 21.
This tool has been properly lubricated and is ready to use.
However, it is recommended that the gears be lubricated
only with Mobil SHC 636 Oil.
Always check the oil level before using this tool, using the
dipstick provided.
n Unplug the tool.
nPlace the base of the saw on a horizontal surface.
nRemove the oil plug using a 6mm hex wrench.
nTip the saw up and let oil drain out into an appropriate
oil container.
nReplace the oil using a small funnel (less than 1/4 in.
spout). Take care to let air out while putting new oil in to
avoid spilling.
DIP STICK
OIL PLUG
Fig. 21
nFill only with Mobil SHC 636 Oil. (Available as a replace-
ment part.)
nFill the gear case until the oil level is between the two
marks on the dipstick. Do not overfill. If the level of oil
raises above the second mark on the dipstick while the
base is on a level surface, overheating may occur.
nReplace the oil plug with a 6mm hex wrench. Do not
overtighten. The O-ring under the head should be com-
pressed slightly. Overtightening will cause the o-ring to
unseat and not seal properly.
Note: With a new saw, change the oil following the first
ten hours of use. This will prolong the life of the tool by
removing the gear particles from the oil when the gears
are breaking in.
BRUSH REPLACEMENT
See Figure 22.
The tool has externally accessible brush assemblies that
should be periodically checked for wear.
BRUSH
ASSEMBLY
n Unplug the tool.
n Remove the brush cap with a torx screwdriver. The brush
assembly is spring loaded and will pop out when you
remove the brush cap.
