Work Stations; How To Get Started - MIRKA DEROS 325CV Manual

* 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 Ltd
accepts no responsibility for the consequences of using declared values instead of actual exposure values for any
individual risk assessment.

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 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 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 rpm 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.
