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.

CAUTION:
Do not turn the adjusting dial when
the tool is running. Failure to do so may result in
the loss of control of the tool and cause an injury.
NOTICE:
If the tool is operated continuously at
low speed for a long time, the motor will get over-
loaded, resulting in tool malfunction.
NOTICE:
The speed adjusting dial can be turned
only as far as 5 and back to 1. Do not force it past
5 or 1, or the speed adjusting function may no
longer work.
NOTE:
Soft no-load rotation function
When the speed adjusting dial is set to "3" or higher,
the tool automatically reduces the speed at no-load to
reduce the vibration under no-load.
Once operation starts with a bit against concrete,
blows per minute increase and reach the numbers as
shown in the table.
When temperature is low, the tool may not have this
function even with the motor rotating.

Pull the switch trigger to light up the lamp. The lamp keeps on
lighting while the switch trigger is being pulled. The lamp goes
out approximately 10 seconds after releasing the switch trigger.
NOTICE:
If the lamp goes off after blinking for a

nology is not working properly. Ask your local
Makita Service Center for repair.
