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

To remove the battery cartridge, withdraw it from the tool while sliding the button on the side of the cartridge.

To insert 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 part on the upper side of the button, it is not locked completely. Insert it fully until the red part 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 inserting the battery car- tridge. If the cartridge does not slide in easily, it is not being inserted correctly. Charging (Fig. 2)

1. Plug the battery charger into the proper A/C voltage source. Two charging lights will flash in green color

2. Insert the battery cartridge into charger until it stops adjusting to the guide of charger. Terminal cover of

charger can be opened with inserting and closed with pulling out the battery cartridge.

3. When the battery cartridge is inserted, the charging light color will change from green to red and charging

will begin. The charging light will keep lighting up lit steadily during charging. One red charging light indicates charged condition in 0 – 80% and two red ones indicates 80 – 100%.

4. With finish of charge, the charging lights will change from two red ones to two green ones.

5. If you leave the battery cartridge in the charger after the charging cycle is complete, the charger will switch

into its ‘‘trickle charge (maintenance charge)’’ mode which will last approximately 24 hours.

6. After charging, unplug the charger from the power source. Refer to the table below for the charging time.

The battery charger is for charging Makita-battery cartridge. Never use it for other purposes or for other manufacturer’s batteries.

When you charge a new battery cartridge or a battery cartridge which has not been used for a long period of time, it may not accept a full charge. This is a normal condition and does not indicate a problem. You can recharge the battery cartridge fully after discharging it completely and recharging a couple of times.

If you charge a battery cartridge from a just- operated tool or battery cartridge which has been left in a location exposed to direct sunlight for a long time, the charging light may flash in red color. If this occurs, wait for a while. Charging will begin after the battery cartridge is cooled by the cooling fan installed in the charger. When the temperature on battery is more than approx. 70°C, two charging lights may flash in red color, and when approx. 50°C – 70°C, one charging light in red color.

If the charging light flashes alternately in green and red color, charging is not possible. The terminals on the charger or battery cartridge are clogged with dust or the battery cartridge is worn out or dam- aged. Cooling system

This charger is equipped with cooling fan for heated battery in order to enable the battery to prove its own performance. Sound of cooling air comes out during cooling, which means no trouble on the charger.

Yellow light will flash for warning in the following cases. – Trouble on cooling fan – Incomplete cool down of battery, such as, being clogged with dust The battery can be charged in spite of the yellow warning light. But the charging time will be longer than usual in this case. Check the sound of cooling fan, vent on the charger and battery, which can be sometime clogged with dust.

The cooling system is in order although no sound of cooling fan comes out, if the yellow warning light will not flash.

Always keep clean the vent on charger and battery for cooling.

The products should be sent to repair or mainte- nance, if the yellow warning light will frequently flash. Conditioning charge Conditioning charge can extend the life of battery by automatically searching the optimum charging condi- tion for the batteries in every situation. The battery employed in the following conditions repeatedly, will be worn out shortly, and yellow warn- ing light may flash.

1. Recharge of battery with its high temperature

2. Recharge of battery with its low temperature

3. Recharge of full charged battery

4. Over-discharge of battery (continue to discharge

battery in spite of down of power.)

5. Recharge under broken cooling system

The charging time of such battery is longer than usual. Trickle charge (Maintenance charge) If you leave the battery cartridge in the charger to prevent spontaneous discharging after full charge, the charger will switch into its ‘‘trickle charge (main- tenance charge)’’ mode and keep the battery car- tridge fresh and fully charged. 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 battery cartridge cool down by inserting it into the charger.

4. Charge the Nickel Metal Hydride battery cartridge

when you do not use it for more than six months. Selecting correct socket 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. Installing or removing socket (Fig. 3 & 4) CAUTION: Always be sure that the tool is switched off and the battery cartridge is removed before installing or removing the socket.

1. For socket without O-ring and pin

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.

2. For socket with O-ring and pin

Move the O-ring out of the groove in the socket and remove the pin from the socket. Fit the socket onto the anvil of the tool so that the hole in the socket is aligned with the hole in the anvil. Insert the pin through the hole in the socket and anvil. Then return the O-ring to the original position in the socket groove to retain the pin. To remove the socket, follow the installation procedures in reverse.

BTW120 (Eng) (’100. 11. 28)Switch action (Fig. 5) 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. To start the tool, simply pull the trigger. Tool speed is increased by increasing pressure on the trigger. Release the trigger to stop. Reversing switch action (Fig. 6) CAUTION:

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.

When not operating the tool, always set the revers- ing switch lever to the neutral position. This tool has a reversing switch to change the direc- tion of rotation. Depress the reversing switch lever from the A side for clockwise rotation or from the B side for counterclockwise rotation. When the revers- ing switch lever is in the neutral position, the switch trigger cannot be pulled. Operation (Fig.7&8) The proper fastening torque may differ depending upon the kind or size of the bolt. The relation between fastening torque and fastening time is shown in the figures. Hold the tool firmly and place the socket over the bolt or nut. Turn the tool on and fasten for the proper fastening time. NOTE:

Hold the tool pointed straight at the bolt or nut without applying excessive pressure on the tool.

Excessive fastening torque may damage the bolt or nut. Before starting your job, always perform a test operation to verify the adequate fastening speed and time for your bolt or nut. 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. When the battery cartridge is discharged almost

completely, voltage will drop and the fastening torque will be reduced.

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.

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 use of the universal joint or the extension bar

somewhat reduces the fastening force of the impact wrench. Compensate by fastening for a longer period of time.

5. Type of materials to be fastened, the manner of
