This tool is a Rotary Hammer for drilling in concrete. In addition, the has a “rotation only mode” without hammering. The mode is suitable for drilling and screw-fastening. Read “Safety Instructions” booklet and the following before using.

Wear ear protection. Exposure to noise can cause hearing loss. Use auxiliary handle (support handle) supplied with the tool. Loss of control can cause personal injury.

Hold power tools by insulated gripping surfaces when per- forming an operation where the cutting tool may contact hidden wiring; contact with a “live” wire will make exposed metal parts of the tool “live” and shock the opera- tor.

4) Be aware that this tool is always

in an operating condition, since it does not have to be plugged into an electrical outlet.

5) If the bit becomes jammed, im-

mediately turn the main switch off to prevent an overload which can damage the battery pack or mo- tor. Use reverse motion to loosen jammed bits.

6) Do not operate the Forward/Reverse

lever when the main switch is on. The battery will discharge rapidly and damage to the unit may occur.

7) Use only a dry, soft cloth for

wiping the unit. Do not use a damp cloth, thinner, benzine, or other volatile solvents for cleaning.

8) When storing or carrying the tool, set

the Forward/Reverse lever to the center position (switch lock).

9) Do not strain the tool by holding the

speed control trigger halfway (speed control mode) so that the motor stops. The protection circuit will ac- tivate and may prevent speed con- trol operation. If this happens, re- lease the speed control trigger and squeeze again for normal operation.- 10 -

10) Be careful not to get dust inside the

chuck. 11) Do not touch the rotating parts to avoid injury.

12) Do not continue to use the tool for

a long time. Stop using the tool from time to time to avoid that the temperature of the motor rises too high. 13) Do not drop the tool.

14) Do not put the tool on the place

where the chuck is depressed. The bit may come off from the chuck and fall down when the chuck is depressed. It may cause injuries. Symbol meaning V Volts Direct current

Variable Speed Control Trigger To set the center of a hole, pull the trigger slightly to start the drill rotation slowly. The more the speed control trigger is pulled, the higher the speed becomes. 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 circui- try starts up when the trigger is pulled for the first time after instal- ling a new 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. Control Panel

(1) LED light Before the use of LED light, always pull the power switch once. Press the LED light on 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.

Use of controls or adjustments or performance of procedures other than those specified herein

result in hazardous radiation exposure.

(2) Overheat warning lamp Off (normaloperation)Illuminated:Overheat(motor)Flashing:Overheat(battery)Indicates operation has been halted due to motor or battery overheating.To protect the motor or battery, be sure to note the following when carry-ing 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- 13 -

(3) Battery low warning lamp Excessive (complete) discharging of lithium ion batteries shortens their service life dramatically. The driver includes a battery protection feature designed to prevent excessive dis- charging of the battery pack.

• The battery protection feature ac- tivates immediately before the battery loses its charge, causing the battery low warning lamp to flash.

• If you notice the battery low warn- ing lamp flashing, charge the bat- tery 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 bat- tery 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 trig- gered, 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 ab- ruptly placed on the motor, even if ample battery charge remains. In this case, both the battery low warning lamp and LED light will flash. (EY78A1) Off (normal operation) Flashing (No charge) Battery protection feature active 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 protec- tion 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 overheat- ing protection feature may not activate.

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

The ambient temperature range is between 0°C (32°F) and 40°C (104°F). If the battery pack is used when the battery temperature is below 0°C (32°F), the tool may fail to function properly. Use the charger at temperatures between 0°C and 40°C, and charge the battery at a tempera- ture similar to that of the battery itself. (There should be no more than a 15°C difference between the temperatures of the battery and the charging location.)- 14 -

• 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. (EY78A1) Installing the Shoulder Strap CAUTION:

[Battery Pack] For Appropriate Use of Battery pack

• For optimum battery life, store the Li- ion battery pack following use without charging it.

• When charging the battery pack, confirm that the terminals on the battery charger are free of foreign substances such as dust and water etc. Clean the terminals before charging the battery pack if any for- eign substances are found on the terminals. The life of the battery pack terminals may be affected by foreign sub- stances such as dust and water etc. during operation.

• When battery pack is not in use, keep it away from other metal objects like: paper clips, coins, keys, nails, screws, or other small metal objects that can make a connection from one terminal to another. Shorting the battery terminals together may cause sparks, burns or a fire.

• When operating the battery pack, make sure the work place is well ven- tilated.

• When the battery pack is removed from the main body of the tool, replace the battery pack cover immediately in order to prevent dust or dirt from con- taminating the battery terminals and causing a short circuit.

Battery Pack Life The rechargeable batteries have a limited life. If the operation time be- comes extremely short after recharg- ing, replace the battery pack with a new one. Battery Recycling ATTENTION: For environmental protection and recycling of materials, be sure that it is disposed of at an officially as- signed location, if there is one in your country. [Battery Charger] Charging Cautions

• If the temperature of the battery pack falls approximately below −10°C (14°F), charging will auto- matically stop to prevent degrada- tion of the battery.

• The ambient temperature range is be- tween 0°C (32°F) and 40°C (104°F). If the battery pack is used when the battery temperature is below 0°C (32°F), the tool may fail to function properly.

• Use the charger at temperatures be- tween 0°C and 40°C, and charge the battery at a temperature similar to that of the battery itself. (There should be no more than a 15°C difference be- tween the temperatures of the battery and the charging location.)

• When charging a cool battery pack (below 0°C (32°F)) 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.

• Cool down the charger when charging more than two battery packs consecutively.

• Do not insert your fingers into contact hole, when holding charger or any other occasions. Storage Do not store the dust collection cup in a compressed position. If kept in a compressed position, it may be impossible to return to the original shape.- 16 - CAUTION: To prevent the risk of fire or dam- age to the battery charger.

• Do not use power source from an engine generator.

• Do not cover vent holes on the charger and the battery pack.

• Unplug the charger when not in use. Li-ion Battery Pack NOTE: Your battery pack is not fully charged at the time of purchase. Be sure to charge the battery before use. Battery charger

3. During charging, the charging lamp

will be lit. When charging is completed, an in- ternal electronic switch will auto- matically be triggered to prevent overcharging.

• Charging will not start if the battery pack is warm (for example, imme- diately after heavy-duty operation). The orange standby lamp will be flashing until the battery cools down. Charging will then begin automat- ically.

4. The charge lamp (green) will flash

slowly once the battery is approxi- mately 80% charged.

5. When charging is completed, the charg-

ing lamp in green color will turn off.

6. If the temperature of the batter pack is

0°C 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 nor- mal operating temperature.

7. Consult an authorized dealer if the

charging lamp (green) does not turn off.

8. If a fully charged battery pack is in-

serted into the charger again, the charging lamp lights up. After several minutes, the charging lamp in green color will turn off.

CAUTION: To prevent the risk of injury, only use accessory or attachment for its stated purpose. Bit adapter (included)

• EY9HX403E Drill chuck (Optional accessory)

• EY9HX400E Use with wood drill bit or metal drill bit with shank of 1.5 mm to 13 mm diameter. Do not use the drill chuck in “Rotation with hammering mode” ( ). Use in "Rotation with hammering mode" may cause break of chuck or bit and result in injury. Hammer chuck (Optional accessory)

• EY9HX401E Use with concrete drill bit, wood drill bit or metal drill bit with straight shank of 2.5 mm to 13 mm diameter. Do not use the hammer chuck with wood drill bit or metal drill bit in “Rotation with hammering mode” ( ). Use in “Rotation with hammering mode” may cause break of bit and result in injury. If you need any assistance for more details regarding these accessories, ask your local service center.

VII. USAGE SUGGESTION

1. If there isn’t enough force pushing down on the bit, the tool may not be able to

blow in hammering mode. This is to prevent the hammering mode from operating with no load. Press down harder on the bit to engage the tool and cause it to blow.

2. In winter or in other situations where the temperature of the unit is low (5°C (41°F)

or below), the blow of the hammering mode may be weaker than normal at the be- ginning stage. This is because the grease becomes stiffer in low temperatures, increasing fric- tion. If this should happen, operating hammering mode with no load for approximately 30 seconds and repeat this 3 times. This will restore its blowing power.- 20 -
