Read “the Safety Instructions” bookletand the following before using.

ADDITIONAL SAFETY RULES 1) Wear ear protectors when using the tool for extended periods.2) Be aware that this tool is always in an operating condition, since it does not have to be plugged into an electrical outlet.3)When screwing or driving into walls, floors, etc., “live” electrical wires may be encountered. DO NOT TOUCH THE HEX QUICK CHUCK OR ANY FRONT METAL PARTS OF THE TOOL! Hold the tool only by the plastic handle to prevent electric shock in case you screw or drive into a “live” wire.4) If the screw driver does not rotate anymore, immediately turn the trigger switch off for a longer period to prevent an overload, which can damage the battery pack or motor. Use reverse motion to loosen jammed bits.5) Do NOT operate the Forward/Reverse lever when the trigger switch is on. The battery will discharge rapidly and damage to the unit may occur.6)During charging, the charger may become slightly warm. This is normal. Do NOT charge the battery for a long period.7) When storing or carrying the tool, set the Forward/Reverse lever to the center position (switch lock).8) Do not strain the tool by holding the trigger switch halfway (speed control mode) so that the motor stops.

. ASSEMBLY NOTE:When attaching or removing a bit or socket, disconnect battery pack from tool or place the trigger switch in the center position (switch lock).Attaching or Removing Bit (EY7270)1. Hold the collar of the quick connect chuck and push it outwards.2. Insert the bit into the chuck.3. The collar will return to its original position when it is released.4. Pull the bit to make sure it does not come out.5. To remove the bit, pull back on the collar in the same way.CAUTION:If the collar does not return to its original position or the bit comes out when pulled on, the bit has not been properly attached.

• Charge the Ni-MH battery fully before storage in order to ensure a longer service life.

• 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. In that case, charge the battery until charging is completed for appropriate functioning of the battery.

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

• When operating with a Ni-MH battery pack, make sure the area is well ventilated. Battery Pack Life The rechargeable batteries have a limited life. If the operation time becomes extremely short after recharging, 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 assigned location, if there is one in your country. EY7270(EU).indb 8 2006/05/25 13:25:00-

Charging NOTE: When you charge the battery pack for the first time, or after prolonged storage, charge it for about 24 hours to bring the battery up to full capacity. Battery charger (EY0110)

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.

2. Insert the battery pack firmly into the

charger. Battery pack Battery charger To AC outlet

3. During charging, the charging lamp will

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

• Charging will not start if the battery pack is warm (for example, immediately after heavy-duty operation). The orange standby lamp will remain on until the battery cools down. Charging will then begin automatically.

4. When charging is completed, the green

charging lamp will start flashing quickly.

5. If the battery pack is too cool, or the

battery pack has not been used for a long time, the charging lamp will light up. In this case it takes longer than normal to fully charge the battery pack.

• If a fully charged battery pack is inserted into the charger again, the charging lamp lights up. After several minutes, the charging lamp may flash quickly to indicate that charging is completed.

If the charging lamp does not light immediately after the charger is plugged in, or if, after the standard charging time passes, the lamp does not go off, consult an authorized dealer. NOTE:

• When charging a cool battery pack (below 5°C (41°F)) in a warm place, leave the battery pack in the place and wait for more than one hour to allow the battery to reach the ambient temperature. Otherwise battery pack may not fully charge.

• Allow the charger to cool down when charging more than two battery packs consecutively.

• Do not insert your fingers into contact hole when holding charger or at any other time. CAUTION: To prevent fire or damage to the battery charger:

• Do not use an engine generator as a power source.

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

. T I G H T E N I N G TORQUE The power required for tightening a bolt will vary depending on the bolt material and size, as well as the material being bolted. Choose the length of tightening time accordingly.Reference values are provided below.(They may vary according to tightening conditions.)

Factors Affecting Tightening Torque The tightening torque is affected by a wide variety of factors including the following. After tightening, always check the torque with a torque wrench.

When the battery pack becomes nearly discharged, the voltage decreases and the tightening torque drops. Bolt Tightening Conditions

• The following bolts are used. Standard bolts: Strength type 6.8 High tensile type 12.9 Explanation of the strength type Bolt yield point (80% of tensile strength) 48 kgf/mm

Longer tightening time results in increased tightening torque. Excessive tightening, however, adds no value and reduces the life of the tool.

3) Different bolt diameters

The size of the bolt diameter affects the tightening torque. Generally, as the bolt diameter increases, tightening torque rises. (EY7271 only)(EY7271 only) EY7270(EU).indb 11 2006/05/25 13:25:06-

4) Tightening conditions

Tightening torque will vary, even with the same bolt, according to grade, length, and torque coefficient (the fixed coefficient indicated by the manufacturer upon production). Tightening torque will vary, even with the same bolting material (e.g. steel), according to the surface finish. Torque is greatly reduced when the bolt and nut start turning together.5) Socket play Torque is lowered as the six-sided configuration of the socket of the wrong size is used to tighten a bolt.6) Switch (Variable speed control trigger) Torque is lowered if the unit is used with the switch not fully pulled out.7) Effect of connecting adaptor The tightening torque will be lowered through the use of a universal joint or a connecting adaptor.

. ACCESSORIES Use only bits suitable for size of drill’s chuck.Use Panasonic original Optional Keyless drill chuck (EY9X003E) and Quick change chuck(EY9HX110E) for maximum performance.
