Overload Protection; Overheat Protection; Overdischarge Protection - Makita HR003GD201 Instruction Manual

Indicator lamps
Lighted Off
NOTE: Depending on the conditions of use and the
ambient temperature, the indication may differ slightly
from the actual capacity.
NOTE: The first (far left) indicator lamp will blink when
the battery protection system works.
Tool / battery protection system
The tool is equipped with a tool/battery protection sys-
tem. This system automatically cuts off power to the
motor to extend tool and battery life. The tool will auto-
matically stop during operation if the tool or battery is
placed under one of the following conditions:

Overload protection

When the battery is operated in a manner that causes
it to draw an abnormally high current, the tool automat-
ically stops without any indication. 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 or battery is overheated, the tool stops
automatically. In this case, let the tool and battery cool
before turning the tool on again.
NOTE: When the tool is overheated, the lamp blinks.

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.
Switch action
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.
► Fig.3: 1. Switch trigger
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.
Speed change
The revolutions and blows per minute can be adjusted
by turning the adjusting dial. The dial is marked 1 (low-
est speed) to 5 (full speed).

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 (For
HR001G/HR002G)
When the speed adjusting dial is set to "4" 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 and there is less
fluidity in grease, the tool may not have this function
even with the motor rotating.
Lighting up the front lamp
► Fig.5: 1. Lamp
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 lamp goes out approximately 10 seconds after
releasing the switch trigger.
CAUTION:
For HR001G/HR002G
If the lamp goes off after blinking for a few sec-
onds, the active feedback sensing technology
is not working properly. Ask your local Makita
Service Center for repair.
NOTE: Use a dry cloth to wipe the dirt off the lens
of the lamp. Be careful not to scratch the lens of the
lamp, or it may lower the illumination.
NOTE: If the dust collection system is installed on the
tool, the lamp of the dust collection system lights up
instead of the lamp of the tool.
