DO NOT operate this Buffer if you do not fully understand the limitations of this tool. DO NOT modify this machine in any way.

BEFORE USING THE BUFFER

1. To avoid serious injury and damage to the tool, read and follow all of the Safety and Operating 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 reproductive harm. Some examples of these chemicals are:

2.  Lead from lead-based paints.

3.  Crystalline silica from bricks, cement, and other masonry products.

4.  Arsenic and chromium from

5. 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. For more information about California Proposition 65 log onto www.rikontools.com.

6.  READ the entire Owner’s Manual. LEARN how to use the tool for its intended applications.

7.  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.

8.  AVOID A DANGEROUS WORKING ENVIRONMENT. DO NOT use electrical tools in a damp environment or expose them to rain.

9.  DO NOT use electrical tools in the presence of flammable liquids or gasses.

10.  ALWAYS keep the work area clean, well lit, and organized. DO NOT work in an environment with floor surfaces that are slippery from debris, grease, and wax.

11.  KEEP VISITORS AND CHILDREN AWAY. DO NOT permit people to be in the immediate work area, especially when the electrical tool is operating.

12.  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.

13.  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.

14.  CHILDPROOF THE WORKSHOP AREA by removing switch keys, unplugging tools from the electrical receptacles, and using padlocks.

15.  ALWAYS UNPLUG THE TOOL FROM THE ELECTRICAL RECEPTACLE when making adjustments, changing parts or performing any maintenance.

16.  KEEP PROTECTIVE GUARDS IN PLACE AND IN WORKING ORDER.

17.  AVOID ACCIDENTAL STARTING. Make sure that the power switch is in the “OFF” position before plugging in the power cord to the electrical receptacle.

18.  REMOVE ALL MAINTENANCE TOOLS from the immediate area prior to turning “ON” the machine.

19.  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.

20.  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.

21.  DO NOT STAND ON A TOOL. Serious injury could result if the tool tips over, or you acciden-tally contact the tool.

22.  DO NOT store anything above or near the tool where anyone might try to stand on the tool to reach it.

23.  MAINTAIN YOUR BALANCE. DO NOT extend yourself over the tool. Wear oil resistant rubber soled shoes. Keep floor clear of debris, grease, and wax.

24.  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.

25.  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.

26.  DO NOT OPERATE TOOL WHILE TIRED, OR UNDER THE INFLUENCE OF DRUGS, MEDICATION OR ALCOHOL.

27.  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.

28.  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.

29.  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 fitting NIOSH/OSHA ap-proved respiratory protection appropriate for the dust exposure, and wash exposed areas with soap and water.

30.  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.

SPECIFIC SAFETY INSTRUCTIONS FOR BUFFERS

Basic precautions should always be followed when using your buffing machine. To reduce the risk of injury, electrical shock, or fire, 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 PROTECTION. Exposure to fine dust and buffing debris particles can be hazardous to your health. Always 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 buffing wheel. Leather gloves are recommended.
5.  INSPECT THE WORK PIECE before buffing 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 without 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 buffing. Should the object being buffed be caught and thrown by the wheel, damage to your fingers may result.
8.  DO NOT STAND IN FRONT OF THE BUF-FER WHEN STARTING IT. Stand to one side of the Buffing 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 buffing 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 buffing 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 buffing 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 buffing wheels when they become too small for effective buffing, 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 buffing wheel firmly on the arbor. DO NOT over-tighten the nut. Only use the wheel flanges provided with the grinder. When selecting a replacement buffing 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 buffing debris and dust from beneath and around the machine. Keep the work area clean.

ELECTRICAL SAFETY

warning

• THIS 120 VOLT TOOL MUST BE GROUNDED WHILE IN USE TO PROTECT THE OPERATOR FROM ELECTRIC SHOCK. IN THE EVENT OF A MALFUNCTION OR 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.
• DO NOT MODIFY THE PLUG PROVIDED. If it will not fit the electrical receptacle, have the prop-er receptacle installed by a qualified electrician.
• 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 qualified electrician or service personnel if you do not completely understand 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.

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 immediately. 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.

ASSEMBLY INSTRUCTIONS

THE BUFFER MUST NOT BE PLUGGED IN AND THE POWER SWITCH MUST BE IN THE OFF POSITION UNTIL ASSEMBLY IS COMPLETE.

INSTALL THE BUFFING WHEELS

1.  Remove the plastic protective sleeves from the 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 flanges 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 buffing wheel when it is installed in step 4.

4.  Slide the Buffing Wheel onto the shaft and butt it against the inner flange.

5.  Slide the Outer Flange onto the shaft and butt it against the buffing wheel. The ‘cup’ side should be facing towards the buffing wheel.

6.  Thread the Arbor Nut onto the shaft to secure the buffing wheel firmly in place. The places pressure against the flanges which press against the buffing 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 buffing wheel following the same procedure outlined above.

INSTALLATION

PERMANENT MOUNTING
Use the mounting holes in the base of the machine to firmly 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 buffing wheels or hinders the movement of the user and the material during use.  If the Buffer is not securely mounted, it will have the ability to move or tip over during buffing operations, and possibly cause the operator’s fingers to contact the rotating wheels, damage to the work piece being buffed, or damage the buffer and any surrounding shop items.

OPERATING THE BENCH GRINDER

The Buffer is designed for hand held buffing, polishing, sharpening, and cleaning operations.

ALWAYS WEAR EYE AND RESPIRATORY PROTECTION! Residue from the buffing wheels and any buffing compound on the wheels are thrown off during buffing and may cause injury.

OPERATING THE BUFFER

1.  Stand to the side of the Buffing 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 buffing wheels to come up to a steady speed for at least one minute before any buffing is done.

4.  Apply buffing compound, if needed, to the rotating rim of the spinning buffing 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 final polishing or buffing of waxed surfaces, no compound is needed. Use the untreated cotton buffing wheel to finish polish these pieces.

5.  Move the work piece towards the buffing 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 finish.

6.  Never force the work piece against the buffing 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 buffing 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 buffing wheel in case your work piece is thrown from your hands and possibly in the direction of your body.
   To avoid serious injury,  never buff on the sides, top or rear of the cotton buffing wheels.

7.  Check the wheel every few minutes to see the condition of the wheel and buffing 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 buffing, or to apply a new/different grade (color) of compound, use a buffing rake to remove the old compound from the wheel.

8. After completing the buffing and polishing operations, turn “OFF” the Buffer by pushing down on the Power Switch. NOTE: It will take a few minutes for the buffing 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 buffing, insert the locking key into the on/off switch.

LUBRICATION
The buffer has sealed lubricated bearings in the motor housing that do not require any additional lubrication from the operator.

CLEANING
Periodically blow areas in and around the buffer to keep the machine and work area clean. Should the buffing wheels become glazed with excessive compound or metallic build-up, clean the wheel with a metal buffing rake or stiff wire brush?

CAUTION : REPLACE the buffing wheels if there is any damage at all. FAILURE to replace a damaged wheel can cause serious injury to the operator. Periodically check all nuts and fasten-ers to make sure that they are secure. Check the power cord, plug, and switch and replace them if they are found to be worn. : DO NOT USE FLAMMABLE MATERIALS to clean the Buffer. A clean dry rag or brush is all that is needed to remove dust and debris buildup. Repairs to the Buffer should be performed by trained personnel only. Unauthorized repairs or replacements with non-factory parts could cause serious injury to the operator and damage to the machine.
