Important safety instructions for battery cartridge

  1. Before using the battery cartridge, read all instructions and cautionary markings on (1) battery charger, (2) battery, and (3) product using the battery.
  2. Do not disassemble or tamper with the battery cartridge. It may result in a fire, excessive heat, or explosion.
  3. If the 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 conductive material.
    (2) Avoid storing battery cartridges in a container with other metal objects such as nails, coins, etc.
    (3) Do not expose the battery cartridge to water or rain. A battery short can cause a large current flow, overheating, possible burns, and even a breakdown.
  6. Do not store and use 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. Do not nail, cut, crush, throw, drop the battery cartridge, or hit a hard object to the battery cartridge. Such conduct may result in a fire, excessive heat, or explosion.
  9. Do not use a damaged battery.
  10. The contained lithium-ion batteries are subject to the Dangerous Goods Legislation requirements. For commercial transports e.g. by third parties, forwarding agents, special requirements on packaging and labeling must be observed. For the preparation of the item being shipped, consulting an expert for hazardous material is required. Please also observe possibly more detailed national regulations. Tape or mask off open contacts and pack up the battery in such a manner that it cannot move around in the packaging.
  11. When disposing of the battery cartridge, remove it from the tool and dispose of it in a safe place. Follow your local regulations relating to the disposal of batteries.
  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 to stuck into the terminals, holes, and grooves of the battery cartridge. It may result in poor performance or breakdown of the tool or battery cartridge.
  17. Unless the tool supports the use of 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.

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 at 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 the function of the tool.
Installing or removing the battery cartridge
CAUTION: Always switch off the tool before installing or removing of the battery cartridge.
CAUTION: Hold the tool and the battery cartridge firmly when installing or removing the battery cartridge. Failure to hold the tool and the battery cartridge firmly may cause them to slip off your hands and result in damage to the tool and battery cartridge and a personal injury.

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. 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.

CAUTION: Always install the battery cartridge 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.
CAUTION: Do not install the battery cartridge forcibly. 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

The battery may have malfunctioned.

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 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
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
This protection works when the remaining battery capacity gets low. In this situation, remove the battery from the tool and charge the battery.

Switch action
CAUTION: Before installing the battery cartridge into the tool, always check to see that the switch trigger actuates properly and returns to the “OFF” position when released.
To prevent the switch trigger from being accidentally pulled, the trigger-lock button is provided. To start the tool, turn the trigger-lock lever in the direction of “B” and pull the switch trigger. Tool speed is increased by increasing pressure on the switch trigger. Release the switch trigger to stop. After use, always turn the trigger-lock lever in the direction of “A”. For continuous operation, pull the switch trigger and then push in the lock button. To stop the tool from the locked position, pull the switch trigger fully to unlock.

Accidental re-start preventive function
Even if you install the battery cartridge while pulling the switch trigger, the tool does not start.
To start the tool, first, release the switch trigger and then pull the switch trigger.

Lighting the lamp
CAUTION: Do not look in the light or see the source of light directly.
To turn on the lamp, slightly pull the switch trigger, and then release it. The lamp goes out approximately 10 seconds after releasing the switch trigger.
► Fig.4: 1. Lamp
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, it may lower the illumination.

ASSEMBLY

CAUTION: Always be sure that the tool is switched off and the battery cartridge is removed before carrying out any work on the tool.

Removing and installing shear blades
CAUTION: Never remove the blades with bare hands. Wear gloves.
The sharp edge of the blade may cause injury.

Removing cutting head
Use the hex wrench (5/32″) to loosen the bolts which secure the cutting head. Pull the cutting head straight out by turning it left and right alternately.
