GENERAL SAFETY RULES WARNING! Read all instructions Failure to follow all instructions listed below may result in electric shock, fire and/or serious injury. The term power tool in all of the warnings listed below refers to your mains operated (corded) power tool or battery operated (cordless) power tool. SAVE THESE INSTRUCTIONS 1) Work area a) Keep work area clean and well lit. Cluttered and dark areas invite accidents. b) 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 of fumes. c) Keep children and bystanders away while operating a power tool. Distractions can cause you to lose control. 2) Electrical safety a) Power tool plugs must match the outlet. Never modify the plug in any way. Do not use any adapter plugs with earthed (grounded) power tools. Unmodified plugs and matching outlets will reduce risk of electric shock. b) Avoid body contact with earthed or grounded surfaces such as pipes, radiators, ranges and refrigerators. There is an increased risk of electric shock if your body is earthed or grounded. c) Do not expose power tools to rain or wet conditions. Water entering a power tool will increase the risk of electric shock. d) Do not abuse the cord. Never use the cord for carrying, pulling or unplugging the power tool. Keep cord away from heat, oil, sharp edges or moving parts. Damaged or entangled cords increase the risk of electric shock. e) When operating a power tool outdoors, use an extension cord suitable for outdoor use. Use of a cord suitable for outdoor use reduces the risk of electric shock. 3) Personal safety a) Stay alert, watch what you are doing and use common sense when operating a power tool. Do not use a power tool while you are tired or under the influence of drugs, alcohol or medication. A moment of inattention while operating power tools may result in serious personal injury. b) Use safety equipment. Always wear eye protection. Safety equipment such as dust mask, non-skid safety shoes, hard hat, or hearing protection used for appropriate conditions will reduce personal injuries. c) Avoid accidental starting. Ensure the switch is in the off position before plugging in. Carrying power tools with your finger on the switch or plugging in power tools that have the switch on invites accidents. d) Remove any adjusting key or wrench before turning the power tool on. A wrench or a key left attached to a rotating part of the power tool may result in personal injury. e) Do not overreach. Keep proper footing and balance at all times. This enables better control of the power tool in unexpected situations. f) Dress properly. Do not wear loose clothing or jewellery. Keep your hair, clothing and gloves away from moving parts.

SAFETY WARNINGS COMMON FOR GRINDING, SANDING, WIRE BRUSHING, POLISHING OR ABRASIVE CUTTING-OFF OPERATIONS a) This power tool is intended to function as a sander or polisher. Read all safety warnings, instructions, illustrations and specifications provided with this power tool. Failure to follow all instructions listed below may result in electric shock, fire and/or serious injury. b) Operations such as grinding, wire brushing or cutting-off are not recommended to be performed with this power tool. Operations for which the power tool was not designed may create a hazard and cause personal injury. c) Do not use accessories which are not specifically designed and recommended by the tool manufacturer. Just because the accessory can be attached to your power tool, it does not assure safe operation. d) The rated speed of the accessory must be at least equal to the maximum speed marked on the power tool. Accessories running faster than their rated speed can break and fly apart. e) The outside diameter and the thickness of your accessory must be within the capacity rating of your power tool. Incorrectly sized accessories cannot be adequately guarded or controlled. f) The arbour size of wheels, flanges, backing pads or any other accessory must properly fit the spindle of the power tool. Accessories with arbour holes that do not match the mounting hardware of the power tool will run out of balance, vibrate excessively and may cause loss of control. g) Do not use a damaged accessory. Before each use inspect the accessory such as abrasive wheels for chips and cracks, backing pad for cracks, tear or excess wear, wire brush for loose or cracked wires. If power tool or accessory is dropped, inspect for damage or install an undamaged accessory. After inspecting and installing an accessory, position yourself and bystanders away from the plane of the rotating accessory and run the power tool at maximum no-load speed for one minute. Damaged accessories will normally break apart during this test time. h) Wear personal protective equipment. Depending on application, use face shield, safety goggles or safety glasses. As appropriate, wear dust mask, hearing protectors, gloves and workshop apron capable of stopping small abrasive or workpiece fragments. The eye protection must be capable of stopping flying debris generated by various operations. The dust mask or respirator must be capable of filtrating particles generated by your operation. Prolonged exposure to high intensity noise may cause hearing loss. i) Keep bystanders a safe distance away from work area. Anyone entering the work area must wear personal protective equipment. Fragments of workpiece or of a broken accessory may fly away and cause injury beyond immediate area of operation. j) Hold power tool by insulated gripping surfaces only, when performing an operation where the cutting accessory may contact hidden wiring or its own cord. Cutting accessory contacting a live wire may make exposed metal parts of the power tool live and shock the operator. k) Position the cord clear of the spinning accessory. If you lose control, the cord may be cut or snagged and your hand or arm may be pulled into the spinning accessory. l) Never lay the power tool down until the accessory has come to a complete stop. The spinning accessory may grab the surface and pull the power tool out of your control. m) Do not run the power tool while carrying it at your side. Accidental contact with the spinning accessory could snag your clothing, pulling the accessory into your body. n) Regularly clean the power tool s air vents. The motor s fan will draw the dust inside the housing and excessive accumulation of powdered metal may cause electrical hazards. o) Do not operate the power tool near flammable materials. Sparks could ignite these materials. p) Do not use accessories that require liquid coolants. Using water or other liquid coolants may result in electrocution or shock. KICKBACK AND RELATED WARNINGS Kickback is a sudden reaction to a pinched or snagged rotating wheel, backing pad or any other accessory. Pinching or snagging causes rapid stalling of the rotating accessory which in turn causes the uncontrolled power tool to be forced in the direction opposite of the accessory s rotation at the point of the binding. For example, if an abrasive wheel is snagged or pinched by the workpiece, the edge of the wheel that is entering into the pinch point can dig into the surface of the material causing the wheel to climb out or kick out. The wheel may either jump toward or away from the operator, depending on direction of the wheel s movement at the point of pinching. Abrasive wheels may also break under these conditions. Kickback is the result of power tool misuse and/or incorrect operating procedures or conditions and can be avoided by taking proper precautions as given below. a) Maintain a firm grip on the power tool and position your body and arm to allow you to resist kickback forces. Always use auxiliary handle, if provided, for maximum control over kickback or torque reaction during start-up. The operator can control torque reactions or kickback forces, if proper precautions are taken. b) Never place your hand near the rotating accessory. Accessory may kickback over your hand. c) Do not position your body in the area where power tool will move if kickback occurs. 9
Kickback will propel the tool in direction opposite to the wheel s movement at the point of snagging. d) Use special care when working corners, sharp edges etc. Avoid bouncing and snagging the accessory. Corners, sharp edges or bouncing have a tendency to snag the rotating accessory and cause loss of control or kickback. e) Do not attach a saw chain woodcarving blade or toothed saw blade. Such blades create frequent kickback and loss of control. SAFETY WARNINGS SPECIFIC FOR SANDING OPERATIONS a) Do not use excessively oversized sanding disc paper. Follow manufacturers recommendations, when selecting sanding paper. Larger sanding paper extending beyond the sanding pad presents a laceration hazard and may cause snagging, tearing of the disc or kickback. SAFETY WARNINGS SPECIFIC FOR POLISHING OPERATIONS a) Do not allow any loose portion of the polishing bonnet or its attachment strings to spin freely. Tuck away or trim any loose attachment strings. Loose and spinning attachment strings can entangle your fingers or snag on the workpiece. PRECAUTIONS ON USING ELECTRONIC SANDER POLISHER 1. Never mount a grinding wheel and attempt to use this tool as a disc grinder. 2. Always hold the body handle and side handle of the power tool firmly. Otherwise the counterforce produced may result in inaccurate and even dangerous operation. 3. Ensure that sparks resulting from use do not create a hazard e. g. do not hit persons, or ignite flammable substances. 4. Always use protective safety glasses and hearing protectors, use other personal protective equipment such as gloves, apron and helmet when necessary. 5. Always use eye and ear protection. Other personal protective equipment such as dust mask, gloves, helmet and apron should be worn when necessary. If in doubt, wear the protective equipment.

PRACTICAL ELECTRONIC SANDER POLISHER APPLICATIONS Motor speed is increased by increasing pressure on the trigger. Release the trigger to stop. For continuous operation, pull the trigger and then push in the lock button. To stop the motor from the locked position, pull the trigger full, then release it. Motor speed can be variable as desired by rotating the dial; it is increased by turning the dial towards 6, decreased by turning it towards 1 (Fig. 1). Select the motor speed appropriate for the work being done. The following table gives the motor speeds corresponding to each indication on the dial scale and shows the types of work for which they are suitable. Dial R.P.M. Type of work Indication 1 600 2 1100 For Polishing 3 1700 } 4 2300 5 2900 } For Sanding 6 3400 CAUTION The dial cannot be rotated further than the 6 or 1 on the scale in their respective directions. 1. Sander operation (1) This unit is designed to provide sufficient polishing (sanding) power with the disc pressed lightly against the sanding/polishing surface: it is equipped with an electronic control circuit to ensure that the motor will not slow down even when loaded. There is therefore no need to press the sanding disc hard against the surface; doing so can overload the motor, subsequently causing the overload cut device to step into operation by cutting the motor s power supply. If this should happen, cut the power switch and turn at the correct motor speed. (2) Do not apply the entire disc surface to the surface of the material. As shown in Fig. 2, the sander should be held at an approximately 15 to 25 angle in relation to the material surface so that the peripheral portion of the sanding disc is offered to the material surface. (3) Precaution immediately after finishing an operation: After turning the switch OFF, do not put the sander down until the sanding disc has come to a complete stop. This precaution will not only prevent a serious accident, but will also reduce the amount of dust and swarf sucked into the machine. 2. Polisher operation (1) Curved surfaces as well as flat surfaces can be efficiently finished. Do not excessively push the polisher against the surface of the material. The weight of the polisher alone is sufficient for effective polishing. Excessive pressure will result in a poor finish and cause possible overload to the motor. (2) Sanding disc, polishing compound or wax should be selected in accordance with the material and the desired surface finish. Maximum polishing effect will be attained by following the following method: Preliminary polishing with sander using a finegrain sanding disc. Polishing with wool bonnet using polishing compound and/or wax. Apply a small quantity of compound and/or wax on material surface and polish with the wool bonnet. CAUTION Carefully guard against permitting the cabtyre cord to touch the wool bonnet or sanding disc during operation. If the cord touches, there is a danger that it may become entangled. MOUNTING AND DISMOUNTING THE SANDING DISC AND WOOL BONNET 1. For Sander operation (Fig. 3) (1) After placing the sanding disc on the rubber pad, thread the washer nut onto the spindle. (2) Press the lock pin to secure the spindle and tighten the washer nut with a wrench. (3) To remove the sanding disc, follow the above procedures in reverse. 2. For Polisher operation (Fig. 4) (1) Insert the washer nut through the rubber pad and thread it onto the spindle. (2) Press the lock pin to secure the spindle and tighten the washer nut with a wrench. (3) As shown in Fig. 5, wrap the rubber pad with the hood of the wool bonnet, and firmly secure it by tightening and tying its draw string. Be sure the excess string is firmly tucked inside the wool bonnet to prevent it from flying out while polishing. CAUTION Improper fitting of the wool bonnet may cause vibration. (4) To remove the wool bonnet, follow the above procedures in reverse. CAUTIONS Use a wrench to tighten the washer nut sufficiently. After releasing the lock pin, check to be sure that it has returned to its normal position. MAINTENANCE AND INSPECTION 1. Inspecting the mounting screws Regularly inspect all mounting screws and ensure that they are properly tightened. Should any of the screws be loose, retighten them immediately. Failure to do so could result in serious hazard. 11
2. Inspecting the carbon brushes (Fig. 6) The motor employs carbon brushes which are consumable parts. Since an excessively worn carbon brush can result in motor trouble, replace the carbon brush with a new one having the same carbon brush No. shown in the figure when it becomes worn to or near the wear limit. In addition, always keep carbon brushes clean and ensure that they slide freely within the brush holders. 3. Replacing a carbon brush Disassemble the brush cap with a minus-head screwdriver. The carbon brush can then be easily removed. 4. Maintenance of the motor The motor unit winding is the very heart of the power tool. Exercise due care to ensure the winding does not become damaged and/or wet with oil or water. 5. Cleaning lock pin section If the lock pin section becomes dirty, clean it at once. 6.
