  CAUTION:
• Always switch off the tool before installing or removing the battery cartridge.
• Hold the tool and the battery cartridge firmly when installing or removing the battery cartridge. Failure to hold the tool and the battery cartridge firmly may cause them to slip off your hands and result in damage to the tool and battery cartridge and a personal injury.

To remove the battery cartridge, slide it from the tool while sliding the button on the front of the cartridge.
To install the battery cartridge, align the tongue on the battery cartridge with the groove in the housing and slip it into place. Insert it all the way until it locks in place with a little click. If you can see the red indicator on the upper side of the button, it is not locked completely.

 CAUTION:

• Always install the battery cartridge fully until the red indicator cannot be seen. If not, it may accidentally fall out of the tool, causing injury to you or someone around you.
• Do not install the battery cartridge forcibly. If the cartridge does not slide in easily, it is not being inserted correctly.

Battery protection system (Lithium-ion battery with star marking) (Fig. 2)

Lithium-ion batteries with a star marking are equipped with a protection system. This system automatically cuts off power to the tool to extend battery life.

The tool will automatically stop during operation if the tool and/or battery are placed under one of the following conditions:

• Overloaded:
  The tool is operated in a manner that causes it to draw an abnormally high current.
  In this situation, stop the application that caused the tool to become overloaded. Then press the start/speed adjusting button again to restart.
  If the tool does not start, the battery is overheated. In this situation, let the battery cool before pressing the start/speed adjusting button.
•  Low battery voltage:
  The remaining battery capacity is too low and the tool will not operate. In this situation, remove and recharge the battery.

Switch action and speed adjusting button (Fig. 3)
To start the tool, press the start/speed adjusting button. The tool starts with high-speed mode. Each time you press the start/speed adjusting button, the speed mode changes in an order of hi-speed, middle speed, and low speed.
To stop the tool, press the stop button.
Refer to the table for the relationship between the speed mode and the kind of work.
