• The values stated in the table are derived from laboratory testing in conformity with stated codes and standards and are not sufficient for risk evaluation. Values measured in a particular workplace may be higher than the declared values. The actual exposure values and amount of risk or harm experienced by an individual are unique to each situation and depend upon the surrounding environment, the way the individual operates the machinery, the particular material being worked, work station design, and the user’s exposure time and physical condition. Mirka Ltd accepts no responsibility for the consequences of using declared values instead of actual exposure values for any individual risk assessment.
• Without dust bag and dust hose.

Proper use of tool

This sander is designed for sanding all types of materials i.e. metals, wood, stone, plastics, etc. using abrasive designed for this purpose. Do not use this sander for any other purpose than specified, without consulting your Mirka dealer. Only use Mirka backing pads that are designed for optimal performance with the brake seal. Never mount a backing pad without a spacing washer. Other backing pads may reduce performance and will increase vibrations.

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”.

Operating instructions

When unpacking the tool, make sure it is intact, complete, and has not been damaged in transport. Never use a damaged tool.
To attach air supply, lift up the cover and connect air supply, close the cover before operating the tool. Use a clean lubricated air supply that will give a measured air pressure at the tool of 6.2 bar (90 psig) when the tool is running with the lever fully pressed. It is recommended to use an approved 10 mm (3/8″) x 8 m (25 ft) maximum-length air hose. The tool should be connected to the air supply as shown in Figure 1.
Do not connect the tool to the compressed air system without incorporating an easy-to-reach and operate air shutoff valve. It is strongly recommended that an air filter, regulator and lubricator (FRL) are used as shown in Figure 1 as this will supply clean, lubricated air at the correct pressure to the tool. Details of such equipment can be obtained from your supplier. If such equipment is not used the tool should be manually lubricated.
To manually lubricate the tool, disconnect the air hose and put 2 to 3 drops of supplied oil or Wurth art. no. 08930505 into the air connection on the tool. Reconnect the tool to the air supply and run the tool slowly for a few seconds to allow air to circulate the oil. If the tool is used frequently, lubricate it on a daily basis.
Lubricate the tool before longer storage or if the tool slows down or loses power.
It is recommended that the air pressure at the tool is 6.2 bar (90 psig) while the tool is running. The tool can run at lower pressures but never higher than 6.2 bar (90 psig).

Maintenance

Always disconnect the air supply before maintenance!
Only use original Mirka spare parts!

Replacing the backing pad

1. Insert the pad wrench between the backing pad and brake seal to hold the spindle nut.
2. Turn the backing pad counterclockwise to remove it.
3. Fit and tighten the new backing pad with washers.
4. Remove the pad wrench.

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.
