battery pack may create a risk of fire when used with 
another battery pack.

3. Use a power source with the voltage specified on the 

nameplate of the charger.

4. Do not attempt to use a step-up transformer, an 

engine generator or DC power receptacle.

5. 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.

6. When battery pack is not in use, keep it away from 

other metal objects like paper clips, coins, keys, nails, 
screws, or other small metal objects that can make a 
connection from one terminal to another. 
Shorting the battery terminals together may cause 
sparks, burns, or a fire.

7. After charging or before attempting any maintenance 

or cleaning, unplug the charger from the power 
source.

8. This battery holder part is not waterproof. Do not use it 

in damp or wet locations. Do not expose it to rain or 
snow. Do not wash it in water.

9. Do not touch the inside of the flashlight head with 

tweezers, metal tools, etc.

10. Under abusive conditions, liquid may be ejected from 

the battery, avoid contact. If contact accidentally 
occurs, flush with water. If liquid contacts eyes, 
additionally seek medical help. Liquid ejected from the 
battery may cause irritation or burns.

11. Do not short the battery cartridge:

(1)

Do not touch the terminals with any conductive 
material.

(2)

Avoid storing battery cartridge in a container 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 breakdown.

12. 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.

13. Be careful not to drop or strike battery.
14. 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.

CAUTION:

1. When the tool is not in use, always switch off and 

remove the battery cartridge from the tool.

2. Do not store the tool and battery cartridge in locations 

where the temperature may reach or exceed 50°C 
(122°F).

3. Do not give the tool a shock by dropping, striking, etc.
4. Do not expose the light to eyes continuously. It may 

hurt them.

5. Do not cover or clog the lit tool with cloth or carton, 

etc. Covering or clogging it may cause a flame.

6. Do not disassemble the charger or battery cartridge; 

take it to a qualified serviceman when service or repair 
is required. Incorrect reassembly may result in a risk 
of electric shock or fire.

7. Use the tools only with specifically designated battery 

packs. Use of any other battery packs may create a 
risk of injury and fire.

8. If operating time has become excessively shorter, stop 

operating immediately. It may result in a risk of 
overheating, possible burns and even an explosion.

9. Do not use a damaged battery.
10. Charge the battery cartridge before completely 

discharged. Always stop tool operation and charge the 
battery cartridge when you notice less tool power.

11. Never recharge a fully charged battery cartridge. 

Overcharging shortens the battery service life.

12. If any problem develops, consult your nearest Makita 

Service Center or dealer. To maintain product safety 
and reliability, repairs, maintenance or adjustment 
should be carried out by Makita Authorized Service 
Center.

13. Charge the battery cartridge once in every six months 

if you do not use it for a long period of time.

SAVE THESE INSTRUCTIONS.

FUNCTIONAL DESCRIPTION

Charging

Charge the battery cartridge with the Makita charger 
before use.

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.

Battery protection system

The protection system is equipped, which automatically 
cuts off the output power for its long service life. The light 
goes off during operation when the remaining battery 
capacity gets low. This is caused by the activation of 
protection system and does not show the light trouble. 
Remove the battery cartridge from the light and charge it.

Switch action (Fig. 2)

CAUTION: 

• Do not look in the LED light or see the source of light 

directly.

The LED light has a cycle of the three-ways status as
