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

Install the battery cartridge fully until the red indicator (13) can not be seen. If not, it may accidentally fall out of the
appliance, causing injury to you or someone around you.
To remove the battery cartridge, slide it from the appliance while sliding the button (14).
To install the battery cartridge, align the tongue on the battery cartridge with the groove in the housing and slip it into
place. Always insert it all the way until it locks in place with a little click. If you can see the red indicator (13) on the
upper side of the button, it is not locked completely.
Do not use force when installing the battery cartridge. If the cartridge does not slide in easily, it is not being
inserted correctly.

Appliance / battery protection system
The appliance is equipped with the protection system. This system automatically cuts off power to the motor to
extend appliance and battery life. The appliance will automatically stop during operation if the appliance or battery is
placed under one of the following conditions.
- Overload protection : When the appliance is operated in a manner that causes it to draw an abnormally high
current, the appliance automatically stops without any indication. In this situation, turn the appliance off and stop
the application that caused the appliance to become overloaded. Then turn the appliance on to restart.
- Overheat protection : When the appliance is overheated, the appliance automatically stops. Let the appliance cool
down before turning it on again.
- Overdischarge protection : When the battery capacity becomes low, the appliance stops automatically. If the
appliance does not operate even when the switches are operated, remove the battery cartridge from the appliance
and charge it.
