Instructions before operating the Buffer.
1. CALIFORNIA PROPOSITION 65 WARNING:
Some dust created by using power tools con-
tains chemicals known to the State of California
to cause cancer, birth defects, or other reproduc-
tive harm. Some examples of these chemicals
are:
• Lead from lead-based paints.
• Crystalline silica from bricks, cement, and
other masonry products.
• Arsenic and chromium from
chemically treated lumber.
Your risk from these exposures varies, depend-
ing 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 lter out microscopic
particles. For more information about California
Proposition 65 log onto www.rikontools.com.
2. READ the entire Owner’s Manual. LEARN
how to use the tool for its intended applications.
3. GROUND ALL TOOLS. If the tool is
supplied with a 3-prong plug, it must be plugged
into a 3-contact electrical receptacle. The 3rd
prong is used to ground the tool and provide
protection against accidental electric shock.
DO NOT remove the 3rd prong. See Grounding
Instructions on page 6.
4. AVOID A DANGEROUS WORKING
ENVIRONMENT. DO NOT use electrical tools in a
damp environment or expose them to rain.
5. DO NOT use electrical tools in the presence of
ammable liquids or gasses.
6. ALWAYS keep the work area clean, well lit,
and organized. DO NOT work in an environment
with oor surfaces that are slippery from debris,
grease, and wax.
7. KEEP VISITORS AND CHILDREN AWAY.
DO NOT permit people to be in the immediate
work area, especially when the electrical tool is
operating.
8. DO NOT FORCE THE TOOL to perform an
operation for which it was not designed. It will do
a safer and higher quality job by only performing
operations for which the tool was intended.
9. WEAR PROPER CLOTHING. DO NOT wear
loose clothing, gloves, neckties, or jewelry. These
items can get caught in the machine during opera-
tions and pull the operator into the moving parts.
The user must wear a protective cover on their
hair, if the hair is long, to prevent it from contact-
ing any moving parts.
10. CHILDPROOF THE WORKSHOP AREA by
removing switch keys, unplugging tools from the
electrical receptacles, and using padlocks.
11. ALWAYS UNPLUG THE TOOL FROM THE
ELECTRICAL RECEPTACLE when making
adjustments, changing parts or performing any
maintenance.
12. KEEP PROTECTIVE GUARDS IN PLACE
AND IN WORKING ORDER.
13. AVOID ACCIDENTAL STARTING. Make
sure that the power switch is in the “OFF” position
before plugging in the power cord to the electrical
receptacle.
14. REMOVE ALL MAINTENANCE TOOLS
from the immediate area prior to turning “ON” the
machine.
Page 3

15. USE ONLY RECOMMENDED
ACCESSORIES. Use of incorrect or improper
accessories could cause serious injury to the op-
erator and cause damage to the tool. If in doubt,
check the instruction manual that comes with that
particular accessory.
16. NEVER LEAVE A RUNNING TOOL UNAT-
TENDED. Turn the power switch to the “OFF”
position. DO NOT leave the tool until it has come
to a complete stop.
17. DO NOT STAND ON A TOOL. Serious injury
could result if the tool tips over, or you acciden-
tally contact the tool.
18. DO NOT store anything above or near the
tool where anyone might try to stand on the tool
to reach it.
19. MAINTAIN YOUR BALANCE. DO NOT
extend yourself over the tool. Wear oil resistant
rubber soled shoes. Keep oor clear of debris,
grease, and wax.
20. MAINTAIN TOOLS WITH CARE. Always
keep tools clean and in good working order. Keep
all blades and tool bits sharp, dress grinding
wheels and change other abrasive accessories
when worn.
21. EACH AND EVERY TIME, CHECK FOR
DAMAGED PARTS PRIOR TO USING THE
TOOL. Carefully check all guards to see that they
operate properly, are not damaged, and perform
their intended functions. Check for alignment,
binding or breaking of moving parts. A guard or
other part that is damaged should be immediately
repaired or replaced.
22. DO NOT OPERATE TOOL WHILE TIRED,
OR UNDER THE INFLUENCE OF DRUGS,
MEDICATION OR ALCOHOL.
23. SECURE ALL WORK. Use clamps or jigs to
secure the work piece. This is safer than attempt-
ing to hold the work piece with your hands.
24. STAY ALERT, WATCH WHAT YOU ARE
DOING, AND USE COMMON SENSE WHEN
OPERATING A POWER TOOL.
A moment of inattention while operating power
tools may result in serious personal injury.
25. ALWAYS WEAR A DUST MASK TO
PREVENT INHALING DANGEROUS DUST OR
AIRBORNE PARTICLES, including wood dust,
crystalline silica dust and asbestos dust.
Direct particles away from face and body.
Always operate tool in well ventilated area and
provide for proper dust removal.
Use dust collection system wherever possible.
Exposure to the dust may cause serious and
permanent respiratory or other injury, including
silicosis (a serious lung disease), cancer, and
death.
Avoid breathing the dust, and avoid prolonged
contact with dust. Allowing dust to get into your
mouth or eyes, or lay on your skin may promote
absorption of harmful material.
Always use properly tting NIOSH/OSHA ap-
proved respiratory protection appropriate for the
dust exposure, and wash exposed areas with
soap and water.
26. USE A PROPER EXTENSION CORD IN
GOOD CONDITION. When using an
extension cord, be sure to use one heavy
enough to carry the current your product will
draw.
The table on page 7 shows the correct size to
use depending on cord length and nameplate
amperage rating. If in doubt, use the next
heavier gauge. The smaller the gauge number,
the larger diameter of the extension cord. If in
doubt of the proper size of an extension cord,
use a shorter and thicker cord. An undersized
cord will cause a drop in line voltage resulting in
a loss of power and overheating.
USE ONLY A 3-WIRE EXTENSION CORD
THAT HAS A 3-PRONG GROUNDING PLUG
AND A 3-POLE RECEPTACLE THAT
ACCEPTS THE TOOL’S PLUG. FIG. A.

SAFETY INSTRUCTIONS
SPECIFIC SAFETY
INSTRUCTIONS FOR BUFFERS
Basic precautions should always be followed
when using your bufng machine. To reduce the
risk of injury, electrical shock, or re, comply with
the safety rules listed below:
1. ALWAYS WEAR EYE PROTECTION.
Everyday eyeglasses are NOT safety glasses.
ALWAYS wear Safety Goggles (that comply with
ANSI standard Z87.1) when operating power
tools. The operation of any buffer or power tool
can result in debris being thrown into your eyes,
which can result in severe and permanent eye
damage.
2. ALWAYS WEAR RESPIRATORY PROTEC-
TION. Exposure to ne dust and bufng debris
particles can be hazardous to your health. Al-
ways wear a NIOSH-approved respirator or dust
mask to reduce your risk of respiratory damage.
3. SECURE THE BUFFER to a stand or work-
bench to prevent sliding or tipping during use.
See page 10.
4. WEAR TIGHT FITTING GLOVES when buff-
ing as the work pieces can get hot or have sharp
edges. Gloves should be tight so they will not get
caught in the bufng wheel. Leather gloves are
recommended.
5. INSPECT THE WORK PIECE before bufng
to insure that there are no loose parts, knots,
splinters or sharp and potentially dangerous
shaped areas that may catch and thrown at the
operator.
6. NEVER BUFF SMALL WORK PIECES with-
out them being properly held by pliers or clamps,
or they will be ripped out of your hands and
possibly cause harm to you or damage the item.
7. NEVER PUT FINGERS INSIDE WORK
PIECES to hold them when bufng. Should the
object being buffed be caught and thrown by the
wheel, damage to your ngers may result.
8. DO NOT STAND IN FRONT OF THE BUF-
FER WHEN STARTING IT. Stand to one side of
the Bufng and turn it “ON”. Wait at the side for
one minute until the machine comes up to full
speed. There is always a possibility that debris
from a glazed or damaged bufng wheel may be
discharged towards the operator.
9. ALLOW THE BUFFER TO ATTAIN FULL
SPEED BEFORE BEGINNING WORK. Hold the
work piece securely, and slowly ease the work into
the bufng wheel. Be careful of any sharp edges
or corners that may catch on the wheel and be
torn from your hands.
10. DO NOT buff using the sides or the rear of
the bufng wheels. Buff only on the wheel slightly
below the wheel center.
11. NEVER STOP THE BUFFER BY FORCING
MATERIAL INTO THE WHEEL. Let the buffer
stop rotating on its own.
12. RESURFACE / DRESS THE BUFFING
WHEEL OFTEN. This will keep the wheel surface
free of residue and glaze. Use a metal rake or stiff
wire brush.
13. THE DIAMETER OF THE BUFFING
WHEELS WILL DECREASE WITH USE. Replace
the bufng wheels when they become too small
for effective bufng, to avoid any damage should
the sewn or bonded material break apart.
14. REPLACE A DAMAGED BUFFING WHEEL
IMMEDIATELY. A damaged wheel can discharge
debris at a high velocity towards the operator.
Tighten the spindle nut just enough to hold the
bufng wheel rmly on the arbor. DO NOT over-
tighten the nut. Only use the wheel anges provid-
ed with the grinder. When selecting a replacement
bufng wheel, use only properly sized wheels, and
verify that the wheel has a higher R.P.M. rating
than the maximum R.P.M. of the Buffer.
15. FREQUENTLY clean bufng debris and dust
from beneath and around the machine. Keep the
work area clean.
Page 5

IMPROPER ELECTRICAL CONNECTION of the
equipment grounding conductor can result in risk
of electric shock. The conductor with the green
insulation (with or without yellow stripes) is the
equipment grounding conductor. DO NOT
connect the equipment grounding conductor
to a live terminal if repair or replacement of the
electric cord or plug is necessary.
CHECK with a qualied electrician or service
personnel if you do not completely under-stand
the grounding instructions, or if you are not sure
the tool is properly grounded.
USE ONLY A 3-WIRE EXTENSION CORD
THAT HAS A 3-PRONG GROUNDING PLUG
AND A 3-POLE RECEPTACLE THAT
ACCEPTS THE TOOL’S PLUG. REPLACE A
DAMAGED OR WORN CORD IMMEDIATELY.
This tool is intended for use on a circuit that has
an electrical receptacle as shown in FIGURE
B. FIGURE B shows a 3-wire electrical plug
and electrical receptacle that has a ground-
ing conductor. If a properly grounded electrical
receptacle is not available, an adapter as shown,
can be used to temporarily connect this plug to
a 2-contact ungrounded receptacle. The adapter
has a rigid lug extending from it that MUST be
connected to a permanent earth ground, such
as a properly grounded receptacle box. THIS
ADAPTER IS PROHIBITED IN CANADA.

BREAKDOWN, grounding provides the path of
least resistance for electric current and reduces
the risk of electric shock. This tool is equipped
with an electric cord that has an equipment
grounding conductor and a grounding plug. The
plug MUST be plugged into a matching electrical
receptacle that is properly installed and grounded
in accordance with ALL local codes and
ordinances.

SAFETY INSTRUCTIONS
EXTENSION CORDS
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.
Check extension cords
before each use. If damaged replace im-
mediately. Never use a tool with a damaged
cord, since touching the damaged area could
cause electrical shock, resulting in serious
injury.
Use a proper extension cord. Only use cords
listed by Underwriters Laboratories (UL). Other
extension cords can cause a drop in line voltage,
resulting in a loss of power and overheating of
tool. When operating a power tool outdoors, use
an outdoor extension cord marked “W-A” or “W”.
These cords are rated for outdoor use and reduce
the risk of electric shock.

arbor shafts, if present.
2. Slide the Spacer onto the arbor shaft. FIG. E.
NOTE: Spacers are not required when mount-
ing several, or thicker, wheels are mounted onto
the shaft. Their purpose is to set the anges
and wheel(s) away from the step in the arbor far
enough so that the arbor nuts can be threaded
onto the arbor to secure the wheels in place.
3. Slide the Inner Flange onto the shaft. The ‘cup’
side should be facing towards the threaded end
of the shaft, and will be against the bufng wheel
when it is installed in step 4.
4. Slide the Bufng Wheel onto the shaft and butt
it against the inner ange.
5. Slide the Outer Flange onto the shaft and butt it
against the bufng wheel. The ‘cup’ side should be
facing towards the bufng wheel.
Page 10
6. Thread the Arbor Nut onto the shaft to secure
the bufng wheel rmly in place. The places
pressure against the anges which press against
the bufng wheel to hold it in place on the shaft.
NOTE: The left hand arbor hex nut is left hand
threaded and is installed by rotating it coun-
terclockwise onto the threaded shaft. The right
hand arbor hex nut is right hand threaded and is
linstalled by rotating it clockwise onto the shaft.
7. Install the second bufng wheel following the
same procedure outlined above.
INSTALLATION
PERMANENT MOUNTING
Use the mounting holes in the base of the
machine to rmly attach the Buffer to a solid work
surface or stand (mounting hardware and stand
not included). See Figure F.
To avoid serious injury, secure the Buffer to a
solid work surface. If the Buffer is not permanently
mounted to a work surface, and remains portable,
the Buffer’s base should be temporarily clamped
to a table or board/plywood. Make sure that the
clamps do not interfere with the bufng wheels or
hinders the movement of the user and the material
during use.
FIG. F
If the Buffer is not securely mounted, it will have the
ability to move or tip over during bufng operations, and possibly cause the
operator’s ngers to contact the rotating wheels, damage to the work piece
being buffed, or damage the buffer and any surrounding shop items.
THE BUFFER MUST NOT BE PLUGGED IN

OPERATING THE BENCH GRINDER
The Buffer is designed for hand held bufng,
polishing, sharpening, and cleaning operations.
ALWAYS WEAR EYE AND
RESPIRATORY PROTECTION!
Residue from the bufng wheels and any bufng
compound on the wheels are thrown off during
bufng and may cause injury.
OPERATING THE BUFFER
1. Stand to the side of the Bufng machine and
plug in the power cord to a suitable power source.
2. Remain to the side of the Buffer and turn it
“ON” by moving the switch to the up position.
3. Allow the bufng wheels to come up to a steady
speed for at least one minute before any bufng
is done.
4. Apply bufng compound, if needed, to the
rotating rim of the spinning bufng wheel. DO NOT
jam or force the compound bar into the wheel with
excess pressure. Ease the compound bar into
the wheel until the whole rim is covered with the
compound material.
For nal polishing or bufng of waxed surfaces,
no compound is needed. Use the untreated cotton
bufng wheel to nish polish these pieces.
5. Move the work piece towards the bufng wheel
until it lightly touches. Move the work piece back
and forth across the lower front surface of the
wheel to buff your work piece to the desired nish.
6. Never force the work piece against the bufng
wheel. Apply the work piece slowly, allowing the
grinding wheel an opportunity to adjust to the
variety of surface shapes of your work piece.
Excessive pressure may slow down the rotating
bufng wheel and motor. This can cause uneven
marks on the work piece and overheat the motor.
DO NOT buff using the sides of the wheels.
DO NOT buff using the top or rear of the bufng
wheel in case your work piece is thrown from your
hands and possibly in the direction of your body.
7. Check the wheel every few minutes to see
the condition of the wheel and bufng compound
coating that was previously applied to the rim of
the wheel.
- If the wheel is worn or damaged, remove and
replace it immediately.
- If the rim surface is glazed over from material
residue from bufng, or to apply a new/different
grade (color) of compound, use a bufng rake to
remove the old compound from the wheel.
Page 11
To avoid serious injury,
never buff on the sides,
top or rear of the cotton bufng wheels.
8. After completing the bufng and polishing
operations, turn “OFF” the Buffer by pushing
down on the Power Switch. NOTE: It will take a
few minutes for the bufng wheels to come to a
complete stop. NEVER STOP THE BUFFER BY
FORCING MATERIAL INTO THE WHEEL. Let
the buffer stop rotating on its own.
9. Unplug the Buffer from the power source.
NOTE: To prevent unauthorized use of the
machine, the power switch has a removable
locking key. With the power switch in the “OFF”
position, pull the locking key out. The Buffer
can not be turned “ON” with the key removed.
To resume bufng, insert the locking key into the
on/off switch.
