General Power Tool Safety Warnings

• Work area safety
  •  Keep work area clean and well lit. Cluttered or dark areas invite accidents.
  •  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 or fumes.
  •  Keep children and bystanders away while operating a power tool. Distractions can cause you to lose control.
• 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 and 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 residual current device (RCD) protected supply. Use of an RCD 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 plugging in tools when the switch is in the on-position 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, clothing and gloves 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 dust-related 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.
• Power tool use and care
  •  Do not overload 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 the battery pack 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 anyone who is 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. 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.
• Service
  • Have your power tool serviced by a qualified repair person using only identical replacement parts. This will ensure that the safety of the power tool is maintained.

Additional Safety Warnings

•  The safety of the tool is granted only by using original Mirka backing pads.
•  Read the Materials Safety Data Sheet (MSDS) for the work surface.
•  If any physical hand/wrist discomfort is experienced, stop working and seek medical attention. Hand, wrist and arm injury may result from repetitive work, motion and overexposure to vibrations.
•  Always refit the cover cap after installing the backing pad.
•  The power supply socket and connector are non-IEC appliance couplers. Only use an original Mirka power supply cable. The Mirka power supply cable can be bought from your Mirka Dealer.
•  Check the tool, backing pad, power cord and fittings regularly for wear.
•  Clean or replace the dust extractor´s collection bag daily. Dust can be highly combustible. Cleaning or replacing the bag also assures optimum performance.
•  If the tool appears to malfunction, stop using it immediately and arrange for service and repair.
•  Keep hands clear of the spinning accessory during use.
•  Do not allow the tool to free speed without taking precautions to protect surrounding people and objects in the event that the abrasive or backing pad should come loose.
•  Do not use in wet conditions.

Proper use of tool

This sander is designed for sanding all types of materials, i.e. metals, wood, stone, plastics, etc. using abrasives designed for this purpose. Do not use this sander for any other purpose than that specified without consulting the manufacturer or the manufacturer’s authorized supplier. Do not use backing pads that have a working speed of less than 8,000 rpm free speed. Only use original Mirka backing pads that are designed for optimal performance with the brake seal. Other backing pads may reduce performance and will increase vibration. The cooling air vents on the housing must be kept clean and free of blockages to ensure air circulation. Any maintenance or repair work requiring the motor housing to be opened may only be carried out by an authorized service centre.

Work stations

The tool is intended to be operated as a hand-held tool. It is always recommended that the tool should be used when standing on a solid floor. It can be in any position but before any such use, the operator must be in a secure position, having a firm grip and footing and be aware that the tool can develop a torque reaction. See the section “Operating instructions”.

How to get started

When unpacking the tool, make sure it is intact, complete and has not been damaged in transport. Never use a damaged tool. Before use, check that the backing pad is correctly attached and tightened. Connect the power cord to the tool. Connect the power cord to a grounded outlet (220 240 VAC, 50/60Hz). In order to get the maximum power from this tool it is recommended to use it with the Mirka dust extractor (or other suitable dust extraction unit) and Mirka net sanding products. The combination of Mirka sanders, Mirka net sanding products and Mirka dust extractor are the basis of Mirka dust-free sanding solutions. The power cord from the tool is connected to the mains supply of the dust extractor. By connecting the tool’s power cord to the outlet on the dust extractor it is possible to use the dust extractor’s autostart function.

Operating instructions

•  The tool is intended to be operated as a hand held tool. The tool can be used in any position. Note! The sander can develop a torque reaction when started.
•  Make sure the sander is switched off. Select a suitable abrasive and secure it to the backing pad. Make sure the abrasive is centred on the backing pad. For optimal performance we recommend a Mirka backing pad and Mirka Net Sanding product.
•  Switching on, changing speed and stopping the sander are described in the “Multi-purpose LED indications (see Figure 2)” chapter.
•  The max rpm can be adjusted by pressing speed+ or speed–, Figure 2. The rpm can be adjusted in the range 4,000 to 8,000 rpm.
•  When sanding, always place the tool on the work surface before starting the tool. Always remove the tool from the work surface before stopping it. This will prevent gouging of the work surface due to excess speed of the abrasive.
•  It is strongly recommended that the tool is used in combination with a Mirka Dust Extractor.
