Tool / battery protection system
The tool is equipped with a tool/battery protection sys-
tem. This system automatically cuts off the power to
extend tool and battery life. The tool will automatically
stop during operation if the tool or battery is placed
under one of the following conditions:

This protection works when the tool/battery is operated
in a manner that causes it to draw an abnormally high
current. 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
This protection works when the tool/battery is over-
heated. The lamp blinks and the overheat warning icon
is displayed on the pressure gauge. In this situation,
turn the tool off and let the tool and battery cool down.
