Description of function and countermeasure
Restart prevention function
Green
Magnet adhesion operates even when the magnet switch is turned on in a condition where the electric drill switch is
turned on or even when the battery pack is attached in a condition where the magnet switch and electric drill switch
are turned on. However, the electric drill will not operate for safety and LED blinks in green.
Turn the electric drill switch off and then turn the switch back on to continue the operation.
Warning function
Red (Rapid)
Warning function is activated in operations described below for safety.
・
When the magnet switch is turned on in a condition where the battery pack is attached and the battery cover is
open (condition where it is pushed toward the main body).
Make sure to draw the battery cover toward the battery pack before starting the operation. (Fig. 23)
・
When the battery cover is pushed toward the main body to detach the battery pack before turning the magnet
switch off
Make sure to detach the battery pack after turning the magnet switch off.
4-2 Battery Remaining Power Display Function
LED blinks three times in a color according to the
remaining power of the battery right after the magnet
switch is turned on.

4-3 Magnetic Force Control Function
Magnetic force is controlled when the electric drill is not operating with the magnet switch turned on to reduce
unnecessary electricity consumption and maintain appropriate magnetic force.
CAUTION
The magnetic force drops completely when voltage of the battery pack decreases to a certain level and may
cause the machine to fall.
Turn the magnet “OFF” when finished with the machine to preserve battery life.
