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

To remove the battery cartridge, withdraw it from the tool while pressing the push buttons on both sides 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 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) Your new battery cartridge is not charged. You will need to charge it before use. Use the battery charger Model DC1411 to charge the battery cartridge. Plug the battery charger into the proper A/C voltage source. The charging light will flash in green color. 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 battery charger. Insert the cartridge fully into the port so that it rests on the charger port floor. When the battery cartridge is inserted, the charging light color will change from green to red and charging will begin. The charging light will remain lit steadily during charging. When the charging light color changes from red to green, the charging cycle is complete. 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. After charging, unplug the charger from the power source. Refer to the table below for the charging time. Battery type Capacity (mAh) Number of cells Charging time 9122 2,000 8 Approx. 60 min. 9133 2,200 8 Approx. 65 min. 9134 2,600 8 Approx. 75 min. 9135 3,000 8 Approx. 90 min. CAUTION:

The battery charger Model DC1411 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 a battery cartridge which has been left in a location exposed to direct sunlight or heat 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 cools. The battery cartridge will cool faster if you remove the battery cartridge from the battery charger.

6991D/6992D (Eng) (’100. 10. 23)• If the charging light flashes alternately in green and red color, a problem exists and charging is not possible. The terminals on the charger or battery cartridge are clogged with dust or the battery cartridge is worn out or damaged. 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 (maintenance charge)’’ mode and keep the battery cartridge 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 temperature at 10°C – 40°C (50°F – 104°F).

Let a hot battery cartridge cool down before charging it.

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

(Model 6991D & 6992D) 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 (Model 6992D)

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. 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 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. 6991D/6992D (Eng) (’100. 10. 23)

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

holding the tool and the tool speed will affect the torque. 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. Installing set plate (Optional accessory) (Fig. 9) Always install the set plate when using battery car- tridges 9100, 9102 or 9102A. Install the set plate on the tool with the screw provided. MAINTENANCE CAUTION: Always be sure that the tool is switched off and the battery cartridge is removed before carrying out any work on the tool. Replacement of carbon brushes (Fig. 10 & 11) Replace carbon brushes when they are worn down to the limit mark. Both identical carbon brushes should be replaced at the same time. To maintain product safety and reliability, repairs, maintenance or adjustment should be carried out by a Makita Authorized Service Center.
