[Battery Charger] Charging Cautions for the Li-ion Battery Pack

ing will automatically stop to prevent degra- dation of the battery. Common Cautions for the Li- ion/Ni-MH/Ni-Cd Battery Pack

• The ambient temperature range is between 0°C (32°F) and 40°C (104°F). If the battery pack is used when the bat

tery temperature is below 0°C (32°F), the tool may fail to function properly.

• 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 bat- tery to the level of the ambient tempera- ture.

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. CAUTION: To prevent the risk of fire or damage 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 (EY0L80)

During charging, the charging lamp will be lit. When charging is completed, an internal electronic switch will automatically be trig- gered 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 be flash

ing until the battery cools down. Charging will then begin automatically.

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

When charging is completed, the charging lamp will start flashing quickly in green color.

6. If the temperature of the battery 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 normal operat- ing temperature.

If the power lamp does not light immediately after the charger is plugged in, or if after the standard charging time the charging lamp does not flash quickly in green, consult an authorized dealer.

8. If a fully charged battery pack is inserted

into the charger again, the charging lamp lights up. After several minutes, the charg- ing lamp may flash quickly to indicate the charging is completed.

. TIGHTENING TORQUE The power required for tightening a bolt will vary, according to 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 followings. After tightening, always check the torque with a torque wrench.1) VoltageWhen the battery pack becomes nearly discharged, the voltage decreases and the tighten-ing torque drops.Bolt Tightening Conditions M12 M14 M16 M10

Bolt Nut WasherSteel platethickness10 mm (3/8")WasherSpring washer Tightening conditions• The following bolts are used. Standard bolts: Strength type 4.8 High tensile type 12.9

Explanation of the strength typeBolt yield point(80% of tensile strength)32 kgf/mm (45000psi)Bolt tensile strength 40 kgf/mm (56000psi) 2) Tightening timeLonger tightening time results in increased tightening torque. Excessive tightening, how-ever, adds no value and reduces the life of the tool.3) Different bolt diametersThe size of the bolt diameter affects the tight-ening torque.Generally, as the bolt diameter increases, tightening torque rises.4) Tightening conditions Tightening torque will vary, even with the same bolt, according to grade, length, and torque coefficient (the fixed coefficient indi-cated by the manufacturer upon produc-tion). Tightening torque will vary, even with the same bolting material (e.g. steel), accord-ing to the surface finish. Torque is greatly reduced when the bolt and nut start turning together.5) Socket playTorque is lowered as the six-sided configu-ration 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 depressed.7) Effect of connecting adaptor The tightening torque will be lowered through the use of a universal joint or a connecting adaptor.
