Functional Description - Makita DHR202 Instruction Manual

12. Use the batteries only with the products specified
by Makita. Installing the batteries to non-compliant
products may result in a fire, excessive heat,
explosion, or leak of electrolyte.
13. If the tool is not used for a long period of time, the
battery must be removed from the tool.
14. During and after use, the battery cartridge may
take on heat which can cause burns or low
temperature burns. Pay attention to the handling
of hot battery cartridges.
15. Do not touch the terminal of the tool immediately
after use as it may get hot enough to cause burns.
16. Do not allow chips, dust, or soil stuck into the
terminals, holes, and grooves of the battery
cartridge. It may cause heating, catching fire, burst
and malfunction of the tool or battery cartridge,
resulting in burns or personal injury.
17. Unless the tool supports the use near high-voltage
electrical power lines, do not use the battery
cartridge near high-voltage electrical power lines.
It may result in a malfunction or breakdown of the tool
or battery cartridge.
18. Keep the battery away from children.
SAVE THESE INSTRUCTIONS.
CAUTION: Only use genuine Makita batteries. Use
of non-genuine Makita batteries, or batteries that have
been altered, may result in the battery bursting causing
fires, personal injury and damage. It will also void the
Makita warranty for the Makita tool and charger.
Tips for maintaining maximum battery life
1. Charge the battery cartridge before completely
discharged. Always stop tool operation and
charge the battery cartridge when you notice less
tool power.
2. Never recharge a fully charged battery cartridge.
Overcharging shortens the battery service life.
3. Charge the battery cartridge with room
temperature at 10 °C - 40 °C (50 °F - 104 °F). Let a
hot battery cartridge cool down before charging it.
4. When not using the battery cartridge, remove it
from the tool or the charger.
5. Charge the battery cartridge if you do not use it for
a long period (more than six months).

FUNCTIONAL DESCRIPTION

CAUTION:
• Always be sure that the tool is switched off and the
battery cartridge is removed before adjusting or
checking function on the tool.
Installing or removing battery cartridge
(Fig. 1)
• Always switch off the tool before installing or removing
of the battery cartridge.
• To remove the battery cartridge, slide it from the tool
while sliding the button on the front of the cartridge.
• To install the battery cartridge, align the tongue on the
battery cartridge with the groove in the housing and slip
it into place. Always insert it all the way until it locks in
place with a little click. If you can see the red indicator
on the upper side of the button, it is not locked
completely. Install it fully until the red indicator cannot
be seen. If not, it may accidentally fall out of the tool,
causing injury to you or someone around you.
• Do not use force when installing the battery cartridge. If
the cartridge does not slide in easily, it is not being
inserted correctly.
Indicating the remaining battery capacity
Only for battery cartridges with the indicator (Fig. 2)
Press the check button on the battery cartridge to indicate
the remaining battery capacity. The indicator lamps light
up for a few seconds.
Indicator lamps
Lighted Off
NOTE:
• Depending on the conditions of use and the ambient
temperature, the indication may differ slightly from the
actual capacity.
• 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 system.
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:
Overload protection
This protection works when the tool 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 or battery is
overheated. In this situation, let the tool and battery cool
before turning the tool on again.
Overdischarge protection
This protection works when the remaining battery capacity
gets low. In this situation, remove the battery from the tool
and charge the battery.
