Operating Instructions - MIRKA DEROS 650CV Instrucciones De Manejo

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. Be
careful and center the abrasive on it. For optimal use of the machine we recommend a MIRKA backing
pad 150mm (6") Code: 8292605011, 125mm 130g (5") Code: 8292502511and Mirka Net Sanding product.
• Switch on the sander by pressing the On/Off key Figure 1. The sander LED is now green.
• The sander can now be started by pressing the lever.
• The speed can be adjusted between the 4000 and max RPM by adjusting the position of the lever.
• The max RPM can be adjusted by pressing the RPM+ or RPM- Figure 1. Every press adds or removes
1000 RPM until it reaches the limits. The RPM can be adjusted in the range 4,000 to 10,000 RPM.
• The tool has two modes of controlling the speed. In the default mode the speed can be adjusted
linearly by adjusting the position of the lever. In the other mode the speed is fixed to the adjusted max
RPM always when the tool is running. By pressing simultaneously both RPM+ and RPM- keys the tool
toggles between the two controlling modes.
• When sanding always place the tool on the work surface then start the tool. Always remove the tool
from the work surface before stopping. 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 is now turned off.
