An extension cord should not be used unless absolutely necessary. If one must be used, ensure the pins on the plug are the same number, size, and shape as those on the charger, and that the cord is properly wired and in good condition. The wire size must be at least as large as specified in the table below:

Do not charge the Battery Cartridge when the temperature is BELOW 10°C (50°F) or ABOVE 40°C (104°F).

Do not attempt to use a step-up transformer, an engine generator, or DC power receptacle.

Do not allow anything to cover or clog the charger vents.

Always cover the battery terminals with the battery cover when the battery cartridge is not used.

A battery short can cause a large current flow, overheating, possible burns, and breakdown. To avoid this: (1) Do not touch the terminals with any conductive material. (2) Avoid storing the battery cartridge in a container with other metal objects such as nails, coins, etc. (3) Do not expose the battery cartridge to water or rain.

Do not store the tool and Battery Cartridge in locations where the temperature may reach or exceed 50°C (122°F).

Do not incinerate the Battery Cartridge even if it is severely damaged or is completely worn out, as it can explode in a fire.

Always switch off the tool before insertion or removal of the battery cartridge.

To remove the battery cartridge, pull out the set plate on the tool and grasp both sides of the cartridge while withdrawing it from the tool.

To insert the battery cartridge, align the tongue on the battery cartridge with the groove in the housing and slip it into place. Snap the set plate back into place. Be sure to close the set plate fully before using the tool.

Do not use force when inserting the battery cartridge. If the cartridge does not slide in easily, it is not being inserted correctly.

Plug the fast charger into your power source.

Insert the battery cartridge so that the plus and minus terminals on the battery cartridge are on the same sides as their respective markings on the fast charger.

Insert the cartridge fully into the port so that it rests on the charger port floor.

Press the start button (red). The charging light will come on and charging will begin.

If the charging light does not come on, press the reset button (yellow) first, then the start button (red).

If the charging light goes out within 10 seconds even after pressing the reset button and start button a couple of times, the battery cartridge is dead. (CAUTION: Wait for more than 5 seconds after the charging light goes out to press the reset button again.)

Replace it with a new one. When the charging light goes out in a certain time, you may remove the fully charged battery cartridge.

Note: If you try to charge a cartridge from a just-operated tool, sometimes the charging light will not come on. If this occurs, let the cartridge cool off for a while. Then re-insert it and try to charge it once more.

If you wish to charge two battery cartridges, allow 15 minutes between chargings on the fast charger.

After charging, unplug the charger from the power source.

Caution: Always be sure that the tool is switched off and the battery cartridge is removed before installing or removing the socket.

To install the socket, push it onto the anvil of the tool until it locks into place.

To remove the socket, simply pull it off.

Always use the correct size socket for bolts and nuts. An incorrect size socket will result in inaccurate and inconsistent fastening torque and/or damage to the bolt or nut.

To start the tool, simply pull the trigger. Tool speed is increased by increasing pressure on the trigger. Release the trigger to stop.

Caution: Before inserting the battery cartridge into the tool, always check to see that the switch trigger actuates properly and returns to the “OFF” position when released.

This tool has a reversing switch to change the direction of rotation.

Move the reversing switch to the left for clockwise rotation or to the right for counterclockwise rotation.

Caution: Always check the direction of rotation before operation. Use the reversing switch only after the tool comes to a complete stop. Changing the direction of rotation before the tool stops may damage the tool.

The fastening torque is affected by a wide variety of factors including the following. After fastening, always check the torque with a torque wrench.

1. Battery: When the battery cartridge is discharged almost completely, voltage will drop and the fastening torque will be reduced.

2. Socket: Failure to use the correct size socket will cause a reduction in the fastening torque. A worn socket (wear on the hex end or square end) will cause a reduction in the fastening torque.

3. Bolt: Even though the torque coefficient and the class of bolt are the same, the proper fastening torque will differ according to the diameter of the bolt. Even though the diameters of bolts are the same, the proper fastening torque will differ according to the torque coefficient, the class of bolt, and the bolt length.

4. The type of materials to be fastened, the manner of holding the tool, and the tool speed will affect the torque.

The following reference table indicates the approximate fastening capacity from a single charge. It may differ under some conditions.

Caution: If the tool is operated continuously until the battery cartridge has discharged, allow the tool to rest for 15 minutes before proceeding with a fresh battery.

The only way to dispose of a Makita battery is to recycle it. The law prohibits any other method of disposal.

To recycle the battery:

1. Remove the battery from the tool.

2. a). Take the battery to your nearest Makita Factory Service Center, or

b). Take the battery to your nearest Makita Authorized Service Center or Distributor that has been designated as a Makita battery recycling location.
