GROUNDING INSTRUCTIONS & METHODS DANGER: Improper use of the grounding plug can result in a risk of electrical shock. This floor machine must be grounded. If it should malfunction or breakdown, grounding provides a path of least resistance for electrical current to reduce the risk of electric shock. This machine is equipped with an equipment-grounded plug. The plug must be inserted into an appropriate outlet that is properly installed and grounded in accordance with all local codes and ordinances If repair or replacement of the cord or plug is necessary, DO NOT connect the grounding wire to either flat blade terminal. The insulated wire with an outer surface that is green with or without yellow stripes is the grounding wire. This floor sander is for use on a nominal 120 volt circuit, and has a grounding plug that looks like the plug illustrated in (Fig A). A temporary adaptor that looks like the adaptor illustrated in (Fig B & C) may be used to connect the plug to a 2-pole receptacle as shown in (Fig A) if a properly grounded outlet is not available. The temporary adaptor should be used only until a properly grounded outlet (Fig A) can be installed by a qualified electrician. The green color rigid ear, lug, or like extending from the adaptor must be connected to a permanent ground such as a properly grounded outlet box cover. Whenever the adaptor is used, it must be held in place by the metal screw (Fig C). WARNING: Improper connection of the equipment-grounding conductor can result in a risk of electrical shock. Check with a qualified electrician or service person if you are in doubt as to whether the outlet is properly grounded. DO NOT modify the plug provided with the machine. If it will not fit the outlet, have a proper outlet installed by a qualified electrician. NOTE: In Canada, use of a temporary adaptor is not permitted by the Canadian Electrical Code. PAGE 4

MARBLE RESTORATION PROCEDURES 1) Inspect the floor for lippage (a tile is higher than the other or seams are not flush or level). When lippage is thicker than a quarter, lippage diamonds must be used. Proceed using all the steps. 2) Check for deep scratches. If there are deep scratches, start with a 200 grit metal bond diamond. 3) Select the grit of diamonds to be used. Use the separate quart water containers to rinse the various diamonds. It is important to keep diamonds separate so you do not cross contaminate. 4) Release some water from the solution tank to lubricate the diamonds, then turn on the machine. It is important to keep an ample amount of water on the floor to keep diamonds lubricated. 5) Use a side to side motion, then forward and back motion to keep floor level. Make a total of (4) passes or (2) cycles at moderate speed, with about a 30% overlap, (See Diagram - Fig A Below). 6) Using a lighted magnifying glass, inspect the floor for uniformity of scratch patterns. 7) Rinse the floor thoroughly and proceed to the next diamond grit (400M, 500RB 800RB). 8) Repeat the above steps until job is completed. 9) When the floor has dried completely with no residue left, apply a marble finisher. We recommend Crystal Clear Marble Finisher. This will enhance and condition the floor. Application Instructions: 1) Use approximately 35 lbs of weight on the machine and a #0 or #1 steel wool pad. 2) MIST 2 or 3 squirts of marble finisher in a 3 Ft X 3 Ft area and run machine until the desired look is achieved. Note: It is better to start using less chemical. You can always reapply. FLOOR MACHINE MAINTENANCE 1) After each use, wipe off all of the polished and painted areas with a clean cloth. 3) Remove the diamond disc from pad driver and rinse discs. 2) Always remove the pad driver/brush when the machine is not in operation, and hang it on a peg or lay flat on its back. NEVER store pad driver/brush face down. 5) If the machine wobbles or vibrates: A) Adjust by turning pad driver/brush 1 /3 turn, then reinstall on machine. B) Inspect the pad driver/brush for warpage or out of round. Lay floor machine down on handle with pad driver/brush in place. With machine running, observe if pad driver/brush appears to wobble or is out of round. Replace if this problem occurs. 4) When the machine is not in use, remove pad driver/brush, wrap power cord around cord hooks and store in a dry area.

PREPARATION FOR RESTORATION 1) Remove furniture from the area and cover nearby floors, foot rails, baseboards, door edges, furniture, etc with poly film and tape edges. 2) Remove all dirt, wax, floor finish or floor sealer entirely by properly stripping, rinsing and allowing the floor to dry completely before proceeding. Be sure floor is neutralized with a neutral cleaner. 4) Fill a 5 gallon pail with water and keep it nearby. 5) Fill quart containers with water to use for the diamonds. 6) Fill the floor machine solution tank and AquaRinse ring tank, wet/dry vacuum or mop bucket with water. 3) Setup Caution Wet Floor signs and rope off the area. TERRAZZO RESTORATION PROCEDURES 1) Mop the floor with a strong stripping solution and allow time for it to activate. 2) Using this machine with 35 to 50 lbs of additional weight, place the machine on a black stripping pad with a silicate carbide sanding screen and begin stripping the floor. 3) Always keep the floor wet, DO NOT let it dry. When finished pickup the slurry with a AquaRinse Vacuum System or wet/dry vacuum. 4) Fill AquaRinse Solution (Ring) Tank or mop bucket with a neutral cleaner solution and rinse the floor. Then vacuum the floor. 5) Add 25 to 35 additional lbs to the floor machine, and attach the diamond disc driver with a 120 Black or 200M Red Diamond Pad. In most cases you will begin with these pads. 6) Release some water from the solution tank to lubricate the diamonds. It is important to keep an ample amount of water on the floor to keep the diamonds lubricated. 7) When operating the floor machine, use a side-toside motion, then a forward-and-back motion. This is to keep the floor level. Make a total of at least (4) passes or (2) cycles at a moderate speed, with about a 30% overlap. (See Diagram - Fig A on page 5) 8) Inspect the floor for scratch pattern uniformity using a lighted magnifying glass. 9) Vacuum and rinse floor thoroughly with the AquaRinse or wet/dry vacuum, then proceed to the next diamond grit level. 10) Repeat steps 6 thru 9 when proceeding through each diamond grit. 11) When the floor has dried completely with no residue left, apply a marble finisher. We recommend Crystal Clear Marble Finisher. This will enhance and condition the floor. Application Instructions: A) Use approximately 35 lbs of weight on the machine and a #0 or #1 steel wool pad. B) Mist 2 or 3 squirts of Crystal Clear in a 3 Ft X 3 Ft area and run machine until desired look is achieved. Note: It is better to start using less chemical. You can always reapply. Floor Maintenance: Maintain the floor with a dust mop on a daily basis. For heavy traffic, repeat step 11 every 2 to 3 weeks or as needed to keep up the floors appearance. PAGE 6
