14. Always charge the battery before use.

15. Never use a battery other than that specied. Do not

connect a usual dry cell, a rechargeable battery other than that specied or a car battery to the power tool.

16. Do not use a transformer containing 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 is good.

19. Use the exploded assembly drawing on this handling

instructions only for authorized servicing.

PRECAUTIONS FOR CHARGER

1. Always charge the battery at an ambient temperature

of 0 – 40°C. A temperature of less than 0°C will result in over charging which is dangerous. The battery cannot be charged at a temperature greater 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 allow foreign matter to enter the hole for

connecting the rechargeable battery.

4. Never disassemble the rechargeable battery or

5. 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.

6. Do not dispose of the battery in re.

If the battery is burnt, it may explode.

7. Using an exhausted battery will damage the charger.

8. 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.

9. Do not insert objects into the air ventilation slots of the

charger. Inserting metal objects or ammable into the charger air ventilation slots will result in an electrical shock hazard or damage to the charger. (Original instructions) SPECIFICATION CHARGER Charging time Approx. 60 minutes (at 20°C) Charging voltage 24 V Weight 0.4 kg 0000Book_UC24SGH_WE_NE.indb 5 2019/05/24 14:57:306 English APPLICATION For charging the HiKOKI BATTERY ○ BSH2420 CHARGING Before using the power tool, charge the battery as follows.

1. Connect the charger’s power cord to the

receptacle. When connecting the plug of the charger to a receptacle, the pilot lamp will blink in red (At 1-second intervals). (2) Regarding the temperature of the rechargeable battery The temperatures for rechargeable batteries are as shown in the Table 2, and batteries that have become hot should be cooled for a while before being recharged. Table 2 Temperatures at which the battery can be recharged -5°C – 50°C (3) Regarding recharging time Table 3 shows the recharging time required according to the type of battery. Table 3 Recharging time (approx. min.) at 20°C Battery capacity (Ah) Battery Voltage (V) Ni-MH BATTERY

60 min. NOTE: The recharging time may vary according to the ambient temperature.

4. Disconnect the charger’s power cord from the

5. Hold the charger rmly and pull out the battery.

NOTE Be sure to pull out the battery from the charger after use, and then keep it. Regarding electric discharge in case of new batteries, etc. As the internal chemical substance of new batteries and batteries that have not been used for an extended period is not activated, the electric discharge might be low when using them the rst and second time. This is a temporary phenomenon, and normal time required for recharging will be restored by recharging the batteries 2-3 times. How to make the batteries perform longer. (1) Recharge the batteries before they become completely exhausted. When you feel that the power of the tool becomes weaker, stop using the tool and recharge its battery. If you continue to use the tool and exhaust the electric current, the battery may be damaged and its life will become shorter. (2) Avoid recharging at high temperatures. A rechargeable battery will be hot immediately after use. If such a battery is recharged immediately after use, its internal chemical substance will deteriorate, and the battery life will be shortened. Leave the battery and recharge it after it has cooled for a while.

2. Insert the battery into the charger.

Firmly insert the battery into the charger as shown in Fig. 1.

When inserting a battery in the charger, the pilot lamp will light up continuously in red. When the battery becomes fully recharged, the pilot lamp will blink in red (At 1-second intervals). (See Table 1) (1) Pilot lamp indication The indications of the pilot lamp will be as shown in Table 1, according to the condition of the charger or the rechargeable battery. Table 1 Indications of the pilot lamp Pilot lamp (red) Before charging Blinks Lights for 0.5 seconds. Does not light for

0.5 seconds. (o for 0.5 seconds)

Battery overheated. Unable to charge. (Charging will commence when battery cools) 0000Book_UC24SGH_WE_NE.indb 6 2019/05/24 14:57:317 English CAUTION ○ If the battery is charged while it is heated because it has been left for a long time in a location subject to direct sunlight or because the battery has just been used, the pilot lamp of the charger lights for 1 second, does not light for 0.5 seconds (o for 0.5 seconds). In such a case, rst let the battery cool, then start charging. ○ Since the built-in micro computer takes about 3 seconds to conrm that the battery being charged with UC24SGH is taken out, wait for a minimum of 3 seconds before reinserting it to continue charging. If the battery is reinserted within 3 seconds, the battery may not be properly charged.

MAINTENANCE AND INSPECTION

1. Inspecting the mounting screws:

Regularly inspect all mounting screws and ensure that they are properly tightened. Should any of the screws be loose, retighten them immediately. Failure to do so could result in serious hazard.

2. Cleaning of the charger

When the charger is stained, wipe with a soft dry cloth or a cloth moistened with soapy water. Do not use chloric solvents, gasoline or paint thinner, for they melt plastics.

3. Store idle charger

When not in use, the charger should be stored in dry, high or locked-up place — out of reach of children. CAUTION In the operation and maintenance of power tools, the safety regulations and standards prescribed in each country must be observed.
