III. ASSEMBLY

Attaching or Removing Bit NOTE:

When attaching or removing a bit, disconnect battery pack from the main unit or place the switch in the center position (switch lock).

The main unit is equipped with a keyless drill chuck.

1. Attachment

Insert the bit and turn the lock collar clockwise (looking from the front) to tighten firmly until it stops clicking. [Fig.1]

1. Removal

Turn the lock collar counterclockwise (looking from the front), then remove the bit. [Fig.2]

NOTE:

If there is excessive play in the chuck, secure the drill in place and open the chuck jaws by turning the lock collar and tighten the screw (left-handed screw) with a screwdriver by turning it counterclockwise (viewed from the front). [Fig.3]

Attaching or Removing Battery Pack

1. To attach the battery pack: [Fig.4] Align the highlighted marker points and attach battery pack. Slide the battery pack until it locks into position.
2. To remove the battery pack: [Fig.4] Push the button and slide the battery pack forward.

EN IV. OPERATION

WARNING!

• Do not inhale smoke emitted from the main unit or battery pack as it may be harmful.

[Main Unit]

CAUTION

When storing or carrying the tool, set the Forward/Reverse lever to the center position (switch lock).

NOTE:

Exercise caution to ensure no objects come into contact with the tool's trigger switch. If an object comes into contact with the tool's trigger switch, even while the Forward/Reverse lever is in the center position (locked), a small amount of electric current may continue flowing, which may cause an excessive discharge from the battery pack and subsequent battery pack failure.

Switch and Forward/Reverse Lever Operation [Fig.5]

1. Push the lever for forward or reverse rotation. Check the direction of the lever before using.
2. Depress the trigger switch slightly to start the tool slowly.
3. Speed will increase by pressing the trigger. The tool stops working immediately by releasing the trigger.
4. When done with an application, lock the switch by centering the lever.

NOTE:

When the brake operates, a braking sound may be heard. This is normal.

CAUTION:

When operating the tool by pulling the trigger, there may be a momentary lag before rotation starts. This does not signal a malfunction.

• This lag occurs as the tool's circuitry starts up when the trigger is pulled for the first time after installing a battery pack or after the tool has not been used for at least 1 minute (or at least 5 minutes when the LED is on). Rotation will start without any lag during second and subsequent operations.

CAUTION:

To prevent damage, do not operate Forward/Reverse lever until the bit comes to a complete stop.

Clutch Torque Setting

Adjust the torque to one of the 18 clutch settings or "E", T (EY7940 only) position.

CAUTION:

• Set the clutch setting at this mark [Fig.6] before actual operation.
• If the clutch handle cannot be set at "drilling" mode after driving with clutch function, set the clutch handle at position 1 and operate the clutch for a second.

Speed Selection

Choose a low or high speed to suit the use. (EY7441, EY7940, EY74A1, EY7451) [Fig.7]

Choose a low, high or auto speed to suite the use (EY7443) [Fig.8]

The more the variable speed control trigger is pulled, the higher the speed becomes.

The EY7443 offers AUTO mode, which detects the load on the tool and automatically switches between HIGH and LOW speed operation.

When the load is low, the tool always starts operation in HIGH speed.

When the tightening torque increases, the tool switches to LOW speed. Keep a secure grip on the tool so that it doesn't twist out of your hands due to the increased torque.

When operating in AUTO mode, whether and when the tool switches between HIGH and LOW speed operation will depend on the specific work conditions. These variations in tool behavior are normal and do not represent a malfunction.

NOTE: When selecting AUTO on the EY7443

During AUTO mode operation, the tool may switch to LOW speed under light loads if there is little remaining battery life or if the battery pack temperature is low (0^ or less). In this case, charge the battery pack or place the battery pack in a warm location for at least one hour to allow it to warm up before use. Depending on the load, the tool may switch back and forth between HIGH and LOW speed operation multiple times. If this switching is undesirable, set the tool to HIGH or LOW speed manually.

CAUTION:

• Check the speed selector switch before use.
• Use in low gear when high torque is required in operation. (Using in high gear with high load can cause motor overload and possible failure.)
• To prevent excessive temperature increase of the tool surface, do not operate the tool continuously using two or more battery packs. The tool needs cool-off time before switching to another pack.
• Ensure that air vents on the sides of the main unit are not blocked during operation. Covering them can cause the tool to overheat and motor damage to occur.
• Do NOT strain the tool (motor). This may cause damage to the tool.
• Avoid contact with air from vent holes during operation as under heavy load this can become hot and potentially cause injury.

Bit-locking Function [Fig.9]

1. With the trigger switch not depressed and a screwdriver bit locked in place, the tool can be used as a manual screwdriver (up to 22.6 N·m, 230 kgf·cm, 199 in·lbs).

There will be a little play in the chuck, but this is not a malfunction.

1. This feature is handy for tightening screws that require more torque than the maximum torque of the driver (position on the clutch), for confirming the tightness of a screw or to loosen an extremely tight screw.

Changing the Belt Hook Location Side [Fig.10]

The belt hook can be attached to either side of the unit.

1. Removing the hook

(1) Remove the nut.
(2) Draw out the hook.

1. Attaching the hook to the other side

(1) Insert the hook in the other side.
(2) Tighten the nut fully so that it securely fastened.

WARNING!

• Be sure to attach the belt hook securely to the main unit with the screw firmly fastened. When the belt hook is not firmly attached to the main unit, the hook may disconnect and the tool may fall. This may result in an accident or injury.
  Periodically check screw for tightness. If found to be loose, tighten firmly.

Be sure to attach the belt hook firmly and securely onto a waist belt or other belt. Pay attention that the tool does not slip off the belt. This may result in an accident or injury.

• When the tool is held by the belt hook, avoid jumping or running with it. Doing so may cause the hook to slip and the tool may fall. This may result in an accident or injury.
• When the tool is hooked onto the waist belt by the belt hook, do not attach driver bits to the tool. A sharp edge object, such as a drill bit, may cause injury or an accident.

EN Control Panel [Fig.11]

(1) LED light [Fig.12]

Before the use of LED light, always pull the power switch once.

Press the LED light button.

The light illuminates with very low current, and it does not adversely affect the performance of the tool during use or its battery capacity.

CAUTION:

• The built-in LED light is designed to illuminate the small work area temporarily.
• Do not use it as a substitute for a regular flashlight, since it does not have enough brightness.
  LED light turns off when the tool has not been used for 5 minutes.

Caution: DO NOT STARE INTO BEAM. Use of controls or adjustments or performance of procedures other than those specified herein may result in hazardous radiation exposure.

(2) Overheat warning lamp [Fig.13]

Indicates operation has been halted due to motor or battery overheating.

To protect the motor or battery, be sure to note the following when carrying out this operation.

• If the motor or battery becomes hot, the protection function will be activated and the motor or battery will stop operating. The overheat warning lamp on the control panel illuminates or flashes when this feature is active.
  If the overheating protection feature activates, allow the tool to cool thoroughly (at least 30 minutes). The tool is ready for use when the overheat warning lamp goes out.

• Avoid using the tool in a way that causes the overheating protection feature to activate repeatedly.

• If the tool is operated continuously under high-load conditions or if it is used in hot-temperature conditions (such as during summer), the overheating protection feature may activate frequently.

• If the tool is used in cold-temperature conditions (such as during winter) or if it is frequently stopped during use, the overheating protection feature may not activate.

The performance of the EY9L42 deteriorates significantly at and below 10^ due to work conditions and other factors.

(3) Battery low warning lamp [Fig.14, 15]

Excessive (complete) discharging of lithium ion batteries shortens their service life dramatically. The driver includes a battery protection feature designed to prevent excessive discharging of the battery pack.

• The battery protection feature activates immediately before the battery loses its charge, causing the battery low warning lamp to flash.
• If you notice the battery low warning lamp flashing, charge the battery pack immediately.
• If it is started with too little battery power remaining, the tool may stop operating without the battery low warning lamp flashing first. This indicates that there is too little battery power remaining to use the tool, and the battery pack should be charged before further use.
• If the tool is subject to a sudden load during use that causes the motor to lock up, the overdischarge prevention sensor may be triggered, and the battery low warning lamp may flash. The lamp will stop flashing once you address the cause of the motor's locking up and cycle the trigger.
• The battery protection feature may activate when a high load is abruptly placed on the motor, even if ample battery charge remains. In this case, both the battery low warning lamp and LED

light will flash (EY7443, EY74A1).

If both the battery low warning lamp and LED light flash, reduce the force with which you are pushing on the driver or, if using a drill driver, adjust the speed switch to a lower setting (EY7443, EY74A1).
- If the tool does not switch between HIGH and LOW speed operation in AUTO mode, the motor will stop and the battery low warning lamp and the overheat warning lamp will alternately flash. It is not breakdown.
If both lamps alternately flash, depress the trigger again. (EY7443)

[Battery Pack]

For Appropriate Use of Battery Pack [Fig.9]

The rechargeable batteries have a limited life.
- For optimum battery life, store the Li-ion battery pack following use without charging it.
- When operating the battery pack, make sure the work place is well ventilated.

For safe use

• The battery pack is designed to be installed by proceeding two steps for safety. Make sure the battery pack is installed properly to the main unit before use.

If the battery pack is not connected firmly when the switch is switched on, the overheat warning lamp and the battery low warning lamp will flash to indicate that safe operation is not possible, and the main unit will not rotate normally. Connect the battery pack into the unit of the tool until the red or yellow label disappears.

[Battery Charger]

Charging

CAUTION:

1) If the temperature of the battery pack falls approximately below -10^ (14^) , charging will automatically stop to prevent degradation of the battery.
2) The ambient temperature range is between 0^ (32^) and 40^ (104^) . If the battery pack is used when the battery temperature is below 0^ (32^) , the tool may fail to function properly.
3) Use the charger at temperatures between 0^ (32^) and 40^ (104^) , and charge the battery at a temperature similar to that of the battery itself. (There should be no more than a 15^ (59^) difference between the temperatures of the battery and the charging location.)
4) When charging a cool battery pack (below 0^ (32^) ) in a warm place, leave the battery pack at the place and wait for more than one hour to warm up the battery to the level of the ambient temperature.
5) Cool down the charger when charging more than two battery packs consecutively.
6) Do not insert your fingers into contact hole, when holding charger or any other occasions.
7) Unplug the charger when not in use. NOTE:

Your battery pack is not fully charged at the time of purchase. Be sure to charge the battery before use.

How to charge

1. Plug the charger into the AC outlet.

NOTE:

Sparks may be produced when the plug is inserted into the AC power supply, but this is not a problem in terms of safety.

1. Connect the battery pack firmly into the charger.

EN

1 Line up the alignment marks and place the battery onto the dock on the charger.

NOTE:

Not all battery packs display the alignment mark (F) (on page 2).

2 Slide forward in the direction of the arrow. [Fig.17]

1. During charging, the charging lamp will be lit. When charging is completed, an internal electronic switch will automatically be triggered to prevent overcharging.

2. Charging will not start if the battery pack is hot (for example, immediately after heavy-duty operation).

The orange standby lamp will be flashing until the battery cools down. Charging will then begin automatically.

1. The charge lamp (green) will flash slowly once the battery is approximately 80% charged.

2. When charging is completed, the charging lamp in green color will turn off.

3. If the temperature of the battery pack is 0^ or less, charging takes longer to fully charge the battery pack than the standard charging time.

Even when the battery is fully charged, it will have approximately 50% of the power of a fully charged battery at normal operating temperature.

1. Consult an authorized dealer if the charging lamp (green) does not turn off.
2. If a fully charged battery pack is inserted into the charger again, the charging lamp lights up. After several minutes, the charging lamp in green color will turn off.
3. Remove the battery pack while the battery pack release button is held up.
