6Lithium-ion batteries with a star marking are equippedwith a protection system. This system automatically cutsoff power to the tool to extend battery life.The tool will automatically stop during operation if the tooland/or battery are placed under one of the following conditions:• Overloaded:The tool is operated in a manner that causesit to draw an abnormally high current.In this situation, slide the slide switch on thetool toward the "O (OFF)" position and stopthe application that caused the tool to becomeoverloaded. Then slide the slide switch towardthe "I (ON)" position again to restart.If the tool does not start, the battery is overheated.In this situation, let the battery cool before slidingthe slide switch toward the "I (ON)" position again.• Low battery voltage:The remaining battery capacity is too low andthe tool will not operate. In this situation,remove and recharge the battery.Indicating the remaining battery capacity(Only for battery cartridges with "B" at the end of themodel number.)12015676Press the check button on the battery cartridge toindicate the remaining battery capacity.

To change the orbitalstroke rate, turn the dial between 1 and 6. The higher thenumber is, the higher the orbital stroke rate is. Preset thedial to the number suitable for your workpiece.NOTE:• The dial cannot be turned directly from 1 to 6 orfrom 6 to 1. Forcing the dial may damage the tool.When changing the dial direction, always turn thedial moving it through each intermediate number.Lighting up the front lampWARNING:• Never look into the light directly.
