SAFETY GUIDELINES
ELECTRICAL SAFETY· 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.· 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.· Do not 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 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.· 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.· If operating a power tool in a damp location is unavoidable, use a ground fault circuit interrupter (GFCI) protected supply. Use of a GFCI reduces 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 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.· Use personal protective equipment. Always wear eye protection. Protective equipment such as a dust mask, non-skid safety shoes, hard hat or hearing protection used for appropriate conditions will reduce personal injuries.· Prevent unintentional starting. Ensure the switch is in the off-position before connecting to power source and/or battery pack, picking up or carrying the tool. Carrying power tools with your finger on the switch or energizing power tools that have the switch on invites accidents.· 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.· Do not overreach. Keep proper footing and balance at all times. This enables better control of the power tool in unexpected situations.· Dress properly. Do not wear loose clothing or jewellery. Keep your hair and clothing away from moving parts. Loose clothes, jewellery or long hair can be caught in moving parts.· If devices are provided for the connection of dust extraction and collection facilities, ensure these are connected and properly used. Use of dust collection can reduce dustrelated hazards.· Do not let familiarity gained from frequent use of tools allow you to become complacent and ignore tool safety principles. A careless action can cause severe injury within a fraction of a second.
SAFETY GUIDELINES
7POWER TOOL USE AND CARE· Do not force the power tool. Use the correct power tool for your application. The correct power tool will do the job better and safer at the rate for which it was designed.· Do not use the power tool if the switch does not turn it on and off. Any power tool that cannot be controlled with the switch is dangerous and must be repaired.· Disconnect the plug from the power source and/or remove the battery pack, if detachable, from the power tool before making any adjustments, changing accessories, or storing power tools. Such preventive safety measures reduce the risk of starting the power tool accidentally.· Store idle power tools out of the reach of children and do not allow persons unfamiliar with the power tool or these instructions to operate the power tool. Power tools are dangerous in the hands of untrained users.· Maintain power tools and accessories. Check for misalignment or binding of moving parts, breakage of parts and any other condition that may affect the power tool’s operation. If damaged, have the power tool repaired before use. Many accidents are caused by poorly maintained power tools.· Keep cutting tools sharp and clean. Properly maintained cutting tools with sharp cutting edges are less likely to bind and are easier to control.· Use the power tool, accessories and tool bits etc. in accordance with these instructions, taking into account the working conditions and the work to be performed. Use of the power tool for operations different from those intended could result in a hazardous situation.· Keep handles and grasping surfaces dry, clean and free from oil and grease. Slippery handles and grasping surfaces do not allow for safe handling and control of the tool in unexpected situations.BATTERY TOOL USE AND CARE· Recharge only with the charger specified by the manufacturer. A charger that is suitable for one type of battery pack may create a risk of fire when used with another battery pack.· Use power tools only with specifically designated battery packs. Use of any other battery packs may create a risk of injury and fire.· When battery pack is not in use, keep it away from other metal objects, like paper clips, coins, keys, nails, screws or other small metal objects, that can make a connection from one terminal to another. Shorting the battery terminals together may cause burns or a fire.· Under abusive conditions, liquid may be ejected from the battery; avoid contact. If contact accidentally occurs, flush with water. If liquid contacts eyes, additionally seek medical help. Liquid ejected from the battery may cause irritation or burns.· Do not use a battery pack or tool that is damaged or modified. Damaged or modified batteries may exhibit unpredictable behaviour resulting in fire, explosion or risk of injury.

SANDINGThis sander can be used for most sanding operations on materials such as wood, plastic, metal and painted surfaces. Do not use the sander for wet sanding.1. Attach the battery pack to the sander. 2. Place the sander on the workpiece so that the sanding paper is fully in contact with the workpiece. 3. Start the sander. 4. For best sanding results, apply light pressure on the sander, but do not force the tool. 5. Move the sander slowly over the workpiece, making successive passes in parallel lines, circles, orcrosswise movements. The removal rate and the sanding pattern are determined by the choice of sanding paper and the work surface. 6. Do not allow sanding on one spot too long, as the sander’s rapid action may remove too much material and make the surface uneven. 7. Upon completion of the sanding operation, remove the sander from the workpiece, turn the sander off and wait until it comes to a complete stop before putting it down.NOTICE: Applying additional pressure only slows the motor, rapidly wears sanding paper, and greatly reduces sander speed. Excessivepressure will overload the motor, possibly causing damage from motor overheating and can result in inferior work.
WARNING!· Before attaching the battery pack to the sander, always check to be sure that the switch is in the off position. Failure to do so could result in accidental starting of the sander, causing possible serious injury.
MAINTENANCEBEFORE EACH USE1. Inspect the sander, the rocker switch and the accessories for damage. 2. Check for damaged, missing, or worn parts.3. Check for loose screws, misalignment or binding of moving parts, or any other condition that may affect the operation.4. If abnormal vibration or noise occurs, turn the tool off immediately and have the problem corrected before further use.5. Detach the battery pack from the tool before cleaning or performing any maintenance. Using compressed air may be the most effective cleaning method. Always wear safety goggles when cleaning tools using compressed air.
