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.

VI. LAMP INDICATIONS

Red Flashing

Red Lit

Green Flashing quickly

Orange Lit

Orange Flashing

Charger is plugged into the AC outlet. Ready to charge.

Now charging

Charging is completed.

Battery pack is warm. Charging will begin when temperature of battery pack drops.

Charging is not possible. Clogged with dust or malfunction of the battery pack.

VII. MAINTENANCE

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

VIII.TIGHTENINGTORQUE

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)Voltage

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