• Overloaded:
The tool is operated in a manner that causes it to
draw an abnormally high current.
In this situation, release the switch trigger on the tool
and stop the application that caused the tool to
become overloaded. Then pull the switch trigger
again to restart.
If the tool does not start, the battery is overheated. In
this situation, let the battery cool before pulling the
switch trigger again.
NOTE:
• The overheat protection works only with BL1415NA.
Switch action (Fig. 2)
CAUTION:
• Before inserting the battery cartridge into the tool,
always check to see that the switch trigger actuates
properly and returns to the "OFF" position when
released.
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.
Reversing switch action (Fig. 3)
CAUTION:
• Always check the direction of rotation before operation.
• Use the reversing switch only after the tool comes to a
complete stop. Changing the direction of rotation
before the tool stops may damage the tool.
• When not operating the tool, always set the reversing
switch lever to the neutral position.
This tool has a reversing switch to change the direction
of rotation. Depress the reversing switch lever from the A
side for clockwise rotation or from the B side for counter-
clockwise rotation.
When the reversing switch lever is in the neutral position,
the switch trigger cannot be pulled.
Turning on the lamp (Fig. 4)
CAUTION:
• Do not look in the light or see the source of light
directly.
Pull the switch trigger to light up the lamp. The lamp
keeps on lighting while the switch trigger is being pulled.
The light automatically goes out 10 seconds after the
switch trigger is released.
NOTE:
• Use a dry cloth to wipe the dirt off the lens of lamp. Be
careful not to scratch the lens of lamp, or it may lower
the illumination.
Auto-Stop setting for number of impacts
This tool has a convenient auto-stop mechanism that
allows you to preset the desired number of impacts in
terms of the application. The tool then stops automati-
cally after reaching the preset number of impacts.

2. Pull the switch trigger approximately 3 seconds
while pressing the indication button, and then
release the switch trigger and the indication button.
3. The lamp on the left side of the display blinks so that
the number of first digit can be changed by pressing
the button.
4. Press the button and choose the desired number.
The displayed number changes fast by keeping
pressing the button. To set the first digit, pull the
switch trigger and then release it.
5. The lamp on the right side of the display starts to
