Always switch off the tool before
installing or removing of the battery cartridge.

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.

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.
CAUTION:
Do not install the battery cartridge
forcibly. If the cartridge does not slide in easily, it is
not being inserted correctly.

Tool / battery protection system
The tool is equipped with a tool/battery protection sys-
tem. This system automatically cuts off power to the
motor to extend tool and battery life. The tool will auto-
matically stop during operation if the tool or battery is
placed under one of the following conditions:
Overload protection
When the battery is operated in a manner that causes
it to draw an abnormally high current, the tool automat-
ically stops without any indication. In this situation, turn
the tool off and stop the application that caused the tool
to become overloaded. Then turn the tool on to restart.
Overheat protection
When the tool or battery is overheated, the tool stops
automatically and the lamp blinks. In this case, let the
tool and battery cool before turning the tool on again.
Overdischarge protection
When the battery capacity is not enough, the tool stops
automatically. In this case, remove the battery from the
tool and charge the battery.
Switch action
WARNING:
Before installing the battery car-
tridge into the tool, always check to see that the
switch trigger actuates properly and returns to
the "OFF" position when released.
► Fig.3: 1. Switch trigger 2. Lock button
To start the tool, simply pull the switch trigger. Tool
speed is increased by increasing pressure on the switch
trigger. Release the switch trigger to stop.
For continuous operation, pull the switch trigger, push
in the lock button and then release the switch trigger.
To stop the tool from the locked position, pull the switch
trigger fully, then release it.
CAUTION:
Switch can be locked in "ON" posi-
tion for ease of operator comfort during extended
use. Apply caution when locking tool in "ON"
position and maintain firm grasp on tool.

the driver bit does not rotate. Push the tool forward to
engage the clutch.
