IMPORTANT SAFETY INSTRUCTIONS FOR
BATTERY CARTRIDGE
1. Before using battery cartridge, read all instruc-
tions and cautionary markings on (1) battery
charger, (2) battery, and (3) product using bat-
tery.
2. Do not disassemble battery cartridge.
3. If operating time has become excessively
shorter, stop operating immediately. It may
result in a risk of overheating, possible burns
and even an explosion.
4. If electrolyte gets into your eyes, rinse them out
with clear water and seek medical attention right
away. It may result in loss of your eyesight.
5. Do not short the battery cartridge:
(1) Do not touch the terminals with any conduc-
tive material.
(2) Avoid storing battery cartridge in a con-
tainer with other metal objects such as nails,
coins, etc.
(3) Do not expose battery cartridge to water or
rain.
A battery short can cause a large current flow,
overheating, possible burns and even a break-
down.
6. Do not store the tool and battery cartridge in
locations where the temperature may reach or
exceed 50°C (122°F).
7. Do not incinerate the battery cartridge even if it
is severely damaged or is completely worn out.
The battery cartridge can explode in a fire.
8. Be careful not to drop or strike battery.
9. Do not use a damaged battery.
10. The contained lithium-ion batteries are subject
to the Dangerous Goods Legislation require-
ments.
For commercial transports e.g. by third parties, for-
warding agents, special requirement on packaging
and labeling must be observed.
For preparation of the item being shipped, consulting
an expert for hazardous material is required. Please
also observe possibly more detailed national regula-
tions.
Tape or mask off open contacts and pack up the bat-
tery in such a manner that it cannot move around in
the packaging.
11. Follow your local regulations relating to disposal
of battery.
12. Use the batteries only with the products speci-
fied by Makita. Installing the batteries to non-com-
pliant products may result in a fire, excessive heat,
explosion, or leak of electrolyte.
SAVE THESE INSTRUCTIONS.
CAUTION:
Only use genuine Makita batteries. Use of non-genu-
ine 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 tempera-
ture at 10°C – 40°C (50°F – 104°F). Let a hot bat-
tery cartridge cool down before charging it.
4. 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 bat-
tery 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 com-
pletely. Install it fully until the red indicator cannot be
seen. If not, it may accidentally fall out of the tool, caus-
ing 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.
Battery protection system (Lithium-ion battery
with star marking) (Fig. 2)
Lithium-ion batteries with a star marking are equipped
with a protection system. This system automatically cuts
off power to the tool to extend battery life.
The tool will automatically stop during operation if the
tool and/or battery are placed under one of the following
conditions:
• Overloaded:
The tool is operated in a manner that causes it to
draw an abnormally high current.
In this situation, release the trigger switch on the tool
and stop the application that caused the tool to
become overloaded. Then pull the trigger switch
again to restart.
If the tool does not start, the battery is overheated.
In this situation, let the battery cool before pulling the
trigger switch again.
• Low battery voltage:
The remaining battery capacity is too low and the
tool will not operate. In this situation, remove and
recharge the battery.
