Tool / battery protection system
The tool is equipped with a tool/battery protection system. This
system automatically cuts off power to the motor 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.
Overload protection
When the tool/battery is operated in a manner that causes it to
draw an abnormally high current, the tool automatically stops. 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 is overheated, the tool stops automatically,
and the battery indicator blink about 60 seconds. In this situ-
ation, let the tool cool down before turning the tool on again.
On
Overdischarge protection
When the battery capacity becomes low, the tool stops
automatically. If the product does not operate even
when the switches are operated, remove the batteries
from the tool and charge the batteries.
Overload alert
If the tool is operated with excessive load, the overload
indicator will blink in red. In this situation, reduce the
load on the tool. Then, the indicator stops blinking.

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.

a negated lock-off button may result in unintentional
operation and serious personal injury.

you simply pull the switch trigger without press-
ing the lock-off button. A switch in need of repair
may result in unintentional operation and serious
personal injury. Return tool to a Makita service center
for proper repairs BEFORE further usage.
To prevent the switch trigger from being accidentally
pulled, a lock-off button is provided. To start the tool,
depress the lock-off button and pull the switch trigger.
