GENERAL OPERATIONAL PRECAUTIONS

1.Keep work area clean. Cluttered areas and benches invite accidents.

2.Avoid dangerous environment. Don’t expose power tools and charger to rain. Don’t use power tools and charger in damp or wet locations. And keep work area well lit. Never use power tools and charger near flammable or explosive materials. Do not use tool and charger in presence of flammable liquids or gases.

3.Keep children away. All visitors should be kept safe distance from work area.

4.Store idle tools and charger. When not in use, tools and charger should be stored in dry, high or locked-up place–out of reach of children. Store tools and charger in a place where the tempera- ture is less than 40°C.

5.Don’t abuse cord. Never carry charger by cord or yank it to disconnect from receptacle. Keep cord from heat, oil and sharp edges.

6.When the charger is not in use, or when being maintained and inspected, disconnect its power cord from the receptacle.

7.To avoid danger, always use only the specified charger.

8.Use only genuine HITACHI replacement parts.

9.Do not use power tools and charger for applications other than those specified in the Handling Instructions.

10.To avoid personal injury, use only the accessories or attachment recommended in these handling instructions or in the HITACHI catalog.

11.Let only the authorized service center do the repairing. The Manufacturer will not be respon- sible for any damages or injuries caused by repair by the unauthorized persons or by mishandling of the tool.

12.To ensure the designed operational integrity of power tools and charger, do not remove installed covers or screws.

13.Always use the charger at the voltage specified on the nameplate.

14.Always charge the battery before use.

15.Never use a battery other than that specified. Do not connect a usual dry cell, a rechargeable battery other than that specified or a car battery to the power tool.

16.Do not use any transformer that has a booster.

17.Do not charge the battery from an engine electric generator or DC power supply.

18.Always charge indoors. Because the charger and battery heat slightly during charging, charge the battery in a place not exposed to direct sunlight; where the humidity is low and the ventilation good.

PRECAUTIONS FOR CHARGER

1.Always charge the battery at a temperature of 10 – 40°C. A temperature of less than 10°C will result

in over charging which is dangerous. The battery cannot be charged at a temperature higher than 40°C. The most suitable temperature for charging is that of 20 – 25°C.

2.Do not use the charger continuously.

When one charging is completed, leave the charger for about 15 minutes before the next charging of battery.

3.Do not charge the battery for more than 1 hour. The battery will be fully charged in about 1 hour and charging should be stopped when 1 hour has elapsed from commencement. Disconnect the charger power cord from the receptacle.

4.Do not allow foreign matter to enter the hole for connecting the rechargeable battery.

5.Never disassemble the rechargeable battery and charger.

6.Never short-circuit the rechargeable battery. Short- circuiting the battery will cause a great electric current and overheat. It results in burn or damage to the battery.

7.Do not dispose of the battery in fire. If the battery is burnt, it may explode.

8.Using an exhausted battery will damage the charger.

9.Bring the battery to the shop from which it was purchased as soon as the post-charging battery life becomes too short for practical use. Do not dispose of the exhausted battery.

10.Do not insert object into the air ventilation slots of the charger.

Inserting metal objects or inflammables into the charger air ventilation slots will result in electrical shock hazard or damaged charger.
