Tips for maintaining maximum battery life

1. Charge the battery cartridge before completely discharged. Always stop tool operation and charge the battery cartridge when you notice less tool power.
2. Never recharge a fully charged battery cartridge. Overcharging shortens the battery service life.
3. Charge the battery cartridge with room temperature at 10°C – 40°C (50°F – 104°F). Let a hot battery cartridge cool down before charging it.
4. Charge the battery cartridge once in every six months if you do not use it for a long period of time.

FUNCTIONAL DESCRIPTION

CAUTION:

• Always be sure that the tool is switched off and the battery cartridge is removed before adjusting or checking function on the tool.

Installing or removing battery cartridge (Fig. 1)
CAUTION:

• Always switch off the tool before installing or removing of the battery cartridge.
• Hold the tool and the battery cartridge firmly when installing or removing 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. Inthis 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 lowspeed. To stop the tool, press the stop button. Refer to the table for the relationship between the speed mode and the kind of work.

NOTE:

• The table shows standard applications. They may differ under certain conditions.

ASSEMBLY

CAUTION:

• Always be sure that the tool is switched off and the battery cartridge is removed before carrying out any work
  on the tool.
