• State and local regulations

WARNING
- Always wear required personal safety protection in accordance with manufacturer's instructions and local/national standards while using this tool.
- The electrical safety of the tool is granted only by using original Mirka backing pads.
- Do not use a power tool if you are tired or under the influence of drugs, alcohol or medication.
- Read the Materials Safety Data Sheet (MSDS) for the work surface.
- Use the tool with dust extraction. A suitable dust extraction unit will reduce hazardous dust.
- Do not overreach. The operator must always stand in a secure position with a firm grip and firm footing on a solid floor.
- Do not wear loose clothing or jewellery. Keep hair, clothing and gloves away from moving parts. Loose clothes, jewellery or long hair can get caught in moving parts.
- 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.
- 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.

CAUTION
- Remove pad wrench before connecting the tool to the power source.
- Keep work area clean and well lit.
• Always ensure that the work piece to be sanded is firmly fixed in place. - Before changing the abrasive always disconnect the power source. Make sure the abrasive is perfectly centred and firmly attached to the backing pad.
- Keep children and bystanders away while operating a power tool. Distractions can cause you to lose control of the tool.
- Always pay attention to work safety. Never carry, store or leave the tool unattended with the power source connected.
- Keep hands clear of the spinning pad 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.

Additional safety warnings
- Read all instructions before using this tool. All operators must be fully trained in the proper, safe use of this tool.
- All maintenance must be carried out by trained personnel. For service, contact a Mirka authorized service centre.
• Always use the tools with a residual current device (RCD) with a rated residual current of 30 mA or less. - 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.
• Always ensure that the power tool specifications correspond to the power source (V, Hz).
• Take care to prevent clothing, ties, hair, cleaning rags, etc. from getting caught in the tool's moving parts. - If the tool appears to malfunction, stop using it immediately and arrange for service and repair.

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 10,000 rpm free speed. Only use original Mirka backing pads that are designed for optimal performance with the brake seal. Never mount a backing pad without a spacer washer. 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 sander 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 sander. Connect the power cord to a grounded outlet (220–240 VAC, 50/60 Hz).
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, net sanding products and Mirka dust extractor are the basis of Mirka dust-free sanding solutions.
The power cord from the sander is connected to the mains supply on the front of the dust extractor. By connecting the sander'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.
- Switch on the sander by pressing the On/Off key, Figure 1. The sander LED (right) is now green.
- The sander can now be started by pressing the lever.
- The speed can be adjusted between 4,000 and max rpm by adjusting the position of the lever.
- The max rpm can be adjusted by pressing rpm+ or rpm-, Figure 1. Each press increases or reduces the speed by 1,000 rpm until it reaches the limits. The rpm can be adjusted in the range 4,000 to 10,000 rpm.
- The tool has two speed control modes. In the default mode the speed can be adjusted linearly by changing the position of the lever. In the other mode the speed remains fixed at the set max rpm when the tool is running. When the rpm+ and rpm- buttons are pressed simultaneously the tool toggles between the two controlling modes.
- 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.
- When sanding is finished, turn off the sander by pressing the On/Off key. The sander LED (right) is now turned off.

Pad saver
Mirka's pad savers are designed to protect the backing pad from wear and tear, when sanding aggressively and continuously with net products. These cost effective pad savers, placed between the backing pad and the sanding disc, should be changed regularly. The pad savers prolong the life of the backing pad.
