GENERAL SAFETY RULES
WARNING!
Read and understand all instructions. Failure to
follow all instructions listed below, may result in electric shock, fire and/or serious personal injury.
SAVE THESE INSTRUCTIONS
WORK AREA
■ Keep your work area clean and well lit. Cluttered
benches and dark areas invite accidents.
■ 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.
■ Keep bystanders, children, and visitors away while
operating a power tool. Distractions can cause you to
lose control.
ELECTRICAL SAFETY
■ 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.
Double insulation eliminates the need for the threewire grounded power cord and grounded power supply
system.
■ 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.
■ Don’t expose power tools to rain or wet conditions.
Water entering a power tool will increase the risk of electric shock.
■ 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.
■ When operating a power tool outside, use an outdoor
extension cord marked “W-A” or “W”. These cords are
rated for outdoor use and reduce the risk of electric shock.
PERSONAL SAFETY
■ 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 oper-
ating power tools may result in serious personal injury.
■ Dress properly. Do not wear loose clothing or jewelry. Contain long hair. Keep your hair, clothing, and
gloves away from moving parts. Loose clothes, jew-
elry, or long hair can be caught in moving parts.
■ 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
accidents.
■ 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.
■ Do not overreach. Keep proper footing and balance
at all times. Proper footing and balance enables better
control of the tool in unexpected situations.
■ Use safety equipment. Always wear eye protection.
Dust mask, nonskid safety shoes, hard hat, or hearing
protection must be used for appropriate conditions.
■ Do not wear loose clothing or jewelry. Contain long
hair. Loose clothes, jewelry, or long hair can be drawn
into air vents.
■ Do not use on a ladder or unstable support. Stable
footing on a solid surface enables better control of the
tool in unexpected situations.
TOOL USE AND CARE
■ Use clamps or other practical way to secure and support the workpiece to a stable platform. Holding the
work by hand or against your body is unstable and may
lead to loss of control.
■ Do not force tool. Use the correct tool for your application. The correct tool will do the job better and safer at
the rate for which it is designed.
■ 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.
■ Disconnect the plug from power source before making any adjustments, changing accessories, or storing the tool. Such preventive safety measures reduce
the risk of starting the tool accidentally.
■ Store idle tools out of the reach of children and other
untrained persons. Tools are dangerous in the hands of
untrained users.
■ 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.
■ 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.
■ 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.
■ Keep the tool and its handle 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 strong solvents to clean your tool. Following
this rule will reduce the risk of loss of control and deterioration of the enclosure plastic.

GENERAL SAFETY RULES
SERVICE
■■
■ Tool service must be performed only by qualified
■■
repair personnel. Service or maintenance performed
by unqualified personnel could result in a risk of injury.
■ When servicing a tool, use only identical replacement parts. Follow instructions in the Maintenance
section of this manual. Use of unauthorized parts or
failure to follow Maintenance Instructions may create a
risk of electric shock or injury.
SPECIFIC SAFETY RULES
■■
■ Hold tool by insulated gripping surfaces when performing an operation where the cutting tool may contact
■■
hidden wiring or its own cord. Contact with a “live” wire will make exposed metal parts of the cutting tool “live” and
shock the operator.
ADDITIONAL SAFETY RULES
■ Know your power tool. Read operator’s manual carefully. Learn its applications and limitations, as well
as the specific potential hazards related to this tool.
Following this rule will reduce the risk of electric shock,
fire, or serious injury.
■ Always wear safety glasses. Everyday eyeglasses
have only impact-resistant lenses; they are NOT
safety glasses. Following this rule will reduce the risk of
serious personal injury.
■ Protect your lungs. Wear a face or dust mask if the
operation is dusty. Following this rule will reduce the
risk of serious personal injury.
■ Protect your hearing. Wear hearing protection during
extended periods of operation. Following this rule will
reduce the risk of serious personal injury.
■ Inspect 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.
■ 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 should be properly repaired or replaced by
an authorized service center. Following this rule will
reduce the risk of shock, fire, or serious injury.
■ Do not abuse cord. Never carry the tool by the cord
or yank it to disconnect it from the receptacle. Keep
cord away from heat, oil, and sharp edges. Following
this rule will reduce the risk of electric shock or fire.
■ 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. A wire gage size (A.W.G.) of at least 14 is recommended 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.
■ Inspect for and remove all nails from lumber before
using this tool. Following this rule will reduce the risk of
serious personal injury.
■ Drugs, alcohol, medication. Do not operate tool while
under the influence of drugs, alcohol, or any medication. Following this rule will reduce the risk of electric
shock, fire, or serious personal injury.
■ Save these instructions. Refer to them frequently and
use 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
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.
Important: 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. When
servicing, use only identical Ryobi replacement parts.
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 related to avoiding electrical shock.
ELECTRICAL CONNECTION
The router 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.

ADJUSTING DEPTH OF CUT
Proper depth of cut depends on several factors: the peak
horsepower of the router motor, the type of cutter, and
the type of wood. A lightweight, low horsepower router is
designed for making shallow cuts. A router with a high
horsepower rating can safely cut deeper. Small cutters,
such as veining bits with 1/16 in. (1.6 mm) cutting
diameters, are designed to remove only small amounts of
wood. Large cutters, such as straight-flute bits, are made
to remove larger amounts of wood. You can make deeper
cuts in soft woods, such as white pine, than in
hardwoods, like oak or maple.
Based on these considerations, choose a depth of cut
that will not place excessive strain on the router motor. If
you find that extra force is needed or that the motor
speed slows down considerably, turn off the router and
reduce the depth of cut. Then, make the cut in two or
more passes.
When routing a groove that is too deep to safely cut in
one pass, it is best to make the cut in several passes. We
recommend that cuts be made at a depth not exceeding
1/8 in. (3.2 mm) and that several passes be made to
reach deeper cuts.
Adjusting the depth of cut for the plunge router is different
from adjusting the depth of cut for the fixed router.

OPERATION
FEEDING THE ROUTER
The “secret” of professional routing and edge shaping
lies in making a careful set-up for the cut and in selecting
the proper rate of feed.
DIRECTION (EXTERNAL)
See Figures 14 and 15.
When routing, the cutter rotates clockwise. Therefore,
you should feed the router into the workpiece from left to
right. When you feed the router from left to right, the
rotation of the cutter pulls the router against the
workpiece. If you feed the router in the opposite direction,
the rotational forces of the spinning bit tend to throw the
router away from the workpiece. This action could cause
you to lose control of the router.
The router motor and bit revolve in a clockwise direction.
This gives the tool a slight tendency to twist in a
counterclockwise direction, especially when the motor
revs up.
Because of the extremely high speed of bit rotation
during a proper feeding operation, there is very little
kickback to contend with under normal conditions.
However, if the bit strikes a knot, hard grain, foreign
object, etc. that affects the normal progress of the cutting
action, there will be a slight kickback. This kickback is
sufficient to spoil the trueness of your cut if you are not
prepared. Such a kickback is always in the direction
opposite to the direction of bit rotation.
To guard against such a kickback, plan your setup and
direction of feed so that you will always be thrusting the
tool—to hold it against whatever you are using to guide
the cut—in the same direction that the leading edge of
the bit is moving. In short, the thrust should be in a
direction that keeps the sharp edges of the bit
continuously biting straight into new (uncut) wood.

DIRECTION (INTERNAL)
See Figure 16.
Whenever you are routing a groove, your travel should be
in a direction that places whatever guide you are using at
the right-hand side. That is, when the guide is positioned
as shown in the first part of the figure, tool travel should
be from left to right and counterclockwise around curves.
When the guide is positioned as shown in the second
part of the figure, tool travel should be right to left and
clockwise around curves. If there is a choice, the first
setup is generally the easiest to use. In either case, the
sideways thrust you use is against the guide.

OPERATION
RATE OF FEED
The proper rate of feed depends on several factors: the
hardness and moisture content of the wood, the depth of
cut, and the cutting diameter of the bit. When cutting
shallow grooves in soft woods such as pine, a faster rate
of feed can be used. When making deep cuts in
hardwoods such as oak, a slower rate of feed should be
used.
The best rate of feed is one that does not slow down the
router motor more than one-third of its no-load speed. If
the router is fed too fast, it will take large chips out of the
wood and leave gouge marks. If the router is fed too slow,
it will scorch or burn the wood.
Feeding Too Fast
See Figure 17.
Clean, smooth routing and edge shaping can be done
only when the bit is revolving at a relatively high speed
and is taking very small bites to produce tiny, cleanly
severed chips. If your router is forced to move forward too
fast, the RPM of the bit becomes slower than normal in
relation to its forward movement. As a result, the bit must
take bigger bites as it revolves. “Bigger bites” mean
bigger chips, and a rougher finish. Bigger chips also
require more power, which could result in the router
motor becoming overloaded.
Under extreme force-feeding conditions the relative RPM
of the bit can become so slow—and the bites it has to
take so large — that chips will be partially knocked off
(rather than fully cut off), resulting in splintering and
gouging of the workpiece.
Your router is an extremely high-speed tool (15,000 25,000 RPM no-load speed), and will make clean,
smooth cuts if allowed to run freely without the overload
of a forced (too fast) feed. Three things that cause “force
feeding” are bit size, depth-of-cut, and workpiece
characteristics. The larger the bit or the deeper the cut,
the more slowly the router should be advanced. If the
wood is very hard, knotty, gummy or damp, the operation
must be slowed still more.
You can always detect “force feeding” by the sound of the
motor. Its high-pitched whine will sound lower and
stronger as it loses speed. Also, the strain of holding the
tool will be noticeably increased.
TOO FAST
TOO SLOW
Fig. 17
Fig. 18
Feeding Too Slow
See Figure 18.
It is also possible to spoil a cut by moving the router
forward too slowly. When it is advanced into the work too
slowly, a revolving bit does not dig into new wood fast
enough to take a bite; instead, it simply scrapes away
sawdust-like particles. Scraping produces heat, which can
glaze, burn, or mar the cut and in extreme cases, can
even overheat the bit so as to destroy its hardness.
In addition, it is more difficult to control a router when the
bit is scraping instead of cutting. With practically no load
on the motor the bit will be revolving at close to top RPM,
and will have a much greater than normal tendency to
bounce off the sides of the cut (especially if the wood has
a pronounced grain with hard and soft areas). As a result,
the cut produced may have rippled, instead of straight
sides.
“Too-slow feeding” can also cause your router to take off
in a wrong direction from the intended line of cut. Always
grasp and hold your router firmly with both hands
when routing.
You can detect “too-slow feeding” by the runaway, highpitched sound of the motor; or by feeling the “wiggle” of
the bit in the cut.

OPERATION
DETERMINING DEPTH OF CUT
See Figure 19
As previously mentioned, the depth of cut is important
because it affects the rate of feed that, in turn, affects the
quality of the cut (and, also, the possibility of damage to
your router motor and bit). A deep cut requires a slower
feed than a shallow one, and a too deep cut will cause
you to slow the feed so much that the bit is no longer
cutting, it is scraping, instead.
Making a deep cut is never advisable. The smaller bits —
especially those only 1/16 inch (1.6 mm) in diameter —
are easily broken off when subjected to too much side
thrust. A large enough bit may not be broken, but if the
cut is too deep a rough cut will result — and it may be
very difficult to guide and control the bit as desired. For
these reasons, we recommend that you do not exceed
1/8 in. depth of cut in a single pass, regardless of the
bit size or the softness or condition of the workpiece.
To make deeper cuts it is therefore necessary to make as
many successive passes as required, lowering the bit 1/8
in. for each new pass. In order to save time, do all the
cutting necessary at one depth setting, before lowering
the bit for the next pass. This will also assure a uniform
depth when the final pass is completed.

ROUTING
Your router is a versatile tool and can be used for many
different applications. You may rout grooves, carve
designs using a template, carve designs by freehand,
taper table and chair legs, mortise door jambs, or create
joints.
ROUTING GROOVES
See Figure 20.
When routing across the face of boards, set router at
desired depth of cut, place the edge of router base
against workpiece, and turn on the router. Slowly feed
the cutter into the workpiece along desired line of cut.
WARNING:
If desired depth of cut is greater than can be safely
cut in one pass, make cuts in two or more passes.
When routing straight cuts across stock, clamp a straight
edge to the workpiece to use as a guide. Position the
straightedge parallel to the line of cut and offset the
distance between the cutting edge of the cutter and the
edge of the router base. Hold the router base against the
straightedge and rout the groove.

Page 18
OPERATION
When routing a groove wider than the diameter of the
cutter, clamp a straightedge on both sides of the cutlines.
Position both guides parallel to the desired line of cut and
spaced equal distances from the desired edges of the
groove. Rout along one guide; then, reverse direction and
rout along the other guide. Clean out any remaining waste
in the center of the groove freehand.
ROUTING BY FREEHAND
See Figure 21.
When used freehand, your router becomes a flexible and
versatile tool. This flexibility makes it possible to easily
rout signs, relief sculptures, etc.
There are two basic techniques for freehand routing:
■■
■ Routing letters, grooves, and patterns into wood.
■■
■■
■ Routing out the background, leaving the letters or
■■
pattern raised above the surface.
When freehand routing, we suggest the following:
■■
■ Draw or layout the pattern on workpiece.
■■
■■
■ Choose the appropriate cutter.
■■
NOTE: A core box or V-groove bit is often used for
routing letters and engraving objects. Straight bits and
ball mills are often used to make relief carvings.
Veining bits are used to carve small, intricate details.
■■
■ Rout the pattern in two or more passes. Make the first
■■
pass at 25% of the desired depth of cut. This will
provide better control as well as being a guide for the
next pass.
NOTE: Do not rout deeper than 1/8 in. per pass.
WARNING:
Do not use large router bits for freehand routing.
Use of large router bits when freehand routing
could cause loss of control or create other hazardous conditions that could cause possible serious
personal injury. When using a router table, large
router bits should be used for edging only. Do not
use router bits that are larger in diameter than the
opening in router subbase for any purpose.

OPERATION
EDGING WITH PILOTS
See Figure 22.
You can cut rabbets and molded edges using piloted
cutters. The pilot, which extends below the cutter, allows
the cutter to turn while the pilot follows the edge of the
workpiece. Some pilots are solid extensions of the cutter.
Others are ball bearing guides that are fastened to the
end of the cutter.
Arbor-type bits with pilots are excellent for quick, easy
edge shaping. They follow workpiece edges that are
either straight or curved. The pilot prevents the bit from
making too deep a cut. Holding the pilot firmly in contact
with the workpiece edge throughout the cut prevents the
cut from becoming too shallow.
Whenever the workpiece thickness together with the
desired depth of cut (as adjusted by router depth setting)
are such that only the top part of the edge is to be
shaped (leaving at least a 1/16 inch [1.6 mm] thick uncut
portion at bottom), the pilot can ride against the uncut
portion, which serves to guide it. However, if the
workpiece is too thin or the bit is set so low that there will
be no uncut edge to ride the pilot against, an extra board
must be placed under the workpiece to act as a guide.
This guide board must have exactly the same contour —
straight or curved — as the workpiece edge. If the guide
is positioned so that its edge is flush with the workpiece
edge, the bit will make a full cut (in as far as the bit
radius). On the other hand, if the guide is positioned as
shown (out from the workpiece edge), the bit will make
less than a full cut — which will alter the shape of the
finished edge.
NOTE: When edge shaping with guides, you can use any
of the piloted bits without a pilot. The size (diameter) of
the pilot determines the maximum cut width that you can
make with the pilot against the workpiece edge. The
small pilot exposes all of the bit; the large one reduces
this amount by 1/16 inch (1.6 mm).
When routing all edges of a panel or board, rout the end
grain first. Any splintering that occurs at the corners will
then be removed when routing the sides. Start each side
1/4 in. (6.35 mm) away from the end. Feed the cutter into
the wood until the pilot contacts the uncut edge. Then,
slowly back the router to shape the corner. Next, move
the router forward to shape the rest of the edge. Be
careful to keep the pilot pressed against the uncut edge.
Repeat this procedure on each side of the panel.

MAINTENANCE
WARNING:
When servicing use only identical Ryobi replacement parts. Use of any other parts may create a hazard or cause
product damage.
GENERAL
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.
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.
Electric tools used on fiberglass material, wallboard,
spackling compounds, or plaster are subject to
accelerated wear and possible premature failure, as the
fiberglass chips and grindings are highly abrasive to
bearings, brushes, commutators, etc. Consequently, we
do not recommended that this tool be used for extended
work on these types of materials. If, however, you do
work with any of these materials, it is extremely important
that you clean the tool frequently by blowing it with an air
jet.
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.
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.
CUTTERS
Get faster and more accurate cutting results by keeping
cutters clean and sharp. Remove all accumulated pitch
and gum from cutters after each use.
When sharpening cutters, sharpen only the inside of the
cutting edge. Never grind the outside diameter. Be sure
when sharpening the end of a cutter to grind the
clearance angle the same as originally ground.
COLLET
Dust and chips may collect on the collet from time to time,
making it necessary to clean the collet. To do so, remove
the collet assembly and wipe it with a clean dry rag.
Clean the taper in the shaft in the same manner. Never
immerse the collet or end of the shaft in a solvent or in
water. Before replacing the collet assembly, put a drop of
SAE30 motor oil on the inside of the nut, on the threads
of the shaft, and on the taper in the shaft. Replace the
collet assembly onto the shaft by hand only. Never
tighten the collet nut without a bit in the collet. This action
could permanently damage the collet.
