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 work place 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 par-
ticular material being worked, work station design and the user's exposure time and physical condition. Mirka accepts
no responsibility for the consequences of using declared values instead of actual exposure values for any individual
risk assessment.

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.
Switch on the sander by pressing the On/Off key, see Figure 1. The sander Multi-purpose LED is now flashing green,
see Figure 1.
The sander can now be started by pressing the lever.
The speed can be adjusted between 4,000 rpm and max by adjusting the position of the lever.
The max rpm can be adjusted by pressing speed+ or speed , see Figure 1. Each press increases or reduces the speed
by 1,000 rpm (DEROS II 750: 500 rpm) until it reaches the limits. For model specific rpm limits, please see technical data
chapter.
