Work Area Safety

• Keep work area clean and well lit. Cluttered or dark areas invite accidents.
• Do not operate in explosive atmospheres, such as in the presence of flammable liquids, gases or dust. Surface finishing can create sparks which may ignite the dust or fumes.
• Keep children and bystanders away while operating. Distractions can cause you to lose control.

Electrical Safety

• Plugs must match the outlets. Never modify the plug in any way. Do not use any adapter plugs with earthed (grounded) equipment. Unmodified plugs and matching outlets will reduce risk of electric shock.
• Do not abuse the cord. Never use the cord for carrying, pulling or unplugging the equipment. Keep cord away from heat, oil, sharp edges and moving parts. Damaged or entangled cords increase the 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 the cabinet or other electrical components to rain or wet conditions. Water entering the cabinet or other electrical components will increase the risk of electric shock.
• When operating 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 in a damp location is unavoidable, use a residual current device (RCD) protected supply. Use of an RCD reduces the risk of electric shock.
• Always ensure that the cabinet’s or other electrical components’ specifications correspond to the power source (V, Hz).

Personal Safety

• Stay alert, watch what you are doing and use common sense when operating the tool. Do not use a while you are tired or under the influence of drugs, alcohol or medication. A moment of inattention while operating may result in serious personal injury.
• Use personal protective equipment. Always wear required protective equipment in accordance with manufacturer’s instructions and local/national standards while using this tool. Protective equipment such as a safety glasses, safety gloves, face mask, non-skid safety shoes, hard hat, or hearing protection used for appropriate conditions will reduce personal injuries.
• Remove any adjusting key or wrench before turning the tool on. A wrench or a key left attached to a rotating part of the tool may result in personal injury.
• Do not overreach. The operator must always stand in a secure position. Keep proper footing and balance at all times. This enables better control of the tool in unexpected situations.
• Dress properly. Do not wear loose clothing or jewelry. Keep your hair, clothing and gloves away from moving parts. Loose clothes, jewelry or long hair can be caught in moving parts.
• Do not let familiarity gained from frequent use of tools allow you to become complacent and ignore safety principles. A careless action can cause severe injury within a fraction of a second.

Use and Care

• Do not force the tool. Use the correct tool for your application. The correct tool will do the job better and safer at the rate for which it was designed.
• Do not use the tool if it does not turn on and off. Any tool that cannot be controlled is dangerous and must be repaired.
• Always pay attention to work safety.
• Always ensure that the work piece to be surface finished is firmly fixed in place.
• Read the Material Safety Data Sheet (MSDS) for the work surface.
• 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. Dust can be highly flammable.
• If devices are not provided for the connection of dust extraction and collection facilities, providing these at the installation by other means can reduce the risk of dust-related hazards.
• Always disconnect the power source before making any adjustments, changing accessories, or storing. Such preventive safety measures reduce the risk of starting accidentally.
• 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.
• Use the 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 tool for operations different from those intended could result in a hazardous situation.
• Maintain power tools and accessories. Check for misalignment or binding of moving parts, breakage of parts and any other condition that may affect the tool’s operation. If damaged, have the tool repaired before use. Many accidents are caused by poorly maintained tools.
• 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

• All maintenance must be carried out by trained personnel. For service, contact a Mirka authorized service Centre.
• If the tool appears to malfunction, stop using it immediately and arrange for service and repair.

Installation Overview

Interfaces

• FLANGE: ISO 9409-1-80-6-M8
• POWER CONNECTION: Phoenix Contact ST-8EP1N8ACK04S
• DUST HOSE CONNECTION: 25 mm

Installation Steps

1. Remove dust protector cap from the connector.
2. Mount the tool on a matching counter-flange. If the force sensor or the robot used has a flange of a different size an adapter may be required. If the counter-flange is larger by a significant amount there may be a need for an increase in tool offset on the adapter to prevent unnecessary wear, or obstruction of the hose and cable.
3. All six (6) M8 screw holes should be used to ensure a robust connection. Note that the pivot pin location is at the front of the tool.
4. On the CV version: Connect the vacuum hose to the tool by fitting the hose on the exhaust and twisting it counter-clockwise.
5. Connect the power cable to the tool by inserting and twisting the connector counter-clockwise to the “lock” position.

AIOS 130 & AIROS 150

1. Hold the spindle with fingers.
2. Turn the backing pad counterclockwise to remove it.
3. Fit and tighten the new backing pad.

Replacing the Brake Seal

Note! This function is only applicable for AIROS 350, 550 and 650.
NOTE! Too much vacuum in your dust extraction system may cause the brake seal to malfunction.

1. Remove the backing pad as described above.
2. Pull the old brake seal out of its groove.
3. Fit the new brake seal in the groove.
4. Fit the backing pad as described above.
5. Check the brake seal function. By changing the number of washers between the spindle and backing pad, the effect of the brake seal can be adjusted.

Replacing the Spindle Bearing

Note! This function is only applicable for AIROS 350, 550, 650 and AIROP 312.

1. Remove the backing pad.

2. Remove the retaining ring. This is done by using a small flathead screwdriver to pry the retaining ring out of its groove, then using a pair of pliers to pull the retaining ring out. The retaining ring is then discarded.

3. Grasp the spindle with pliers and pull it out of the bearing package. Pulling the bearing will create a partial vacuum in the bearing chamber, which will result in some resistance. This pressure difference will gradually equalise.
   Note: The backing pad can also be used to remove the spindle bearing, by fitting it back on and using it to pull out the spindle.

4. Insert the new spindle bearing kit into the spindle chamber.

5. Insert the new retaining ring using a small flathead screwdriver. The ring should click in place.

6. Check if the spindle bearing is properly installed. The retaining ring should be in its designated groove and should be able to rotate.
