Frequently Asked Questions - UC18YGH HiKOKI

How to charge a battery with the UC18YGH?

Plug the charger into a mains socket (the red LED flashes). Insert the battery respecting polarity. The LED becomes steady during charging and flashes again when charging is complete. Then unplug and remove the battery.

Which batteries are compatible with this charger?

The UC18YGH charger is compatible with HiKOKI batteries from series OB712S, EB7S, EB714S, FEB7S, EB7B, EB912S, EB9S, EB914S, EB914, FEB9S, EB9B, EB924, EB926H, EB930H, EB933X, EB1212S, EB12S, EB1214S, EB1214L, FEB12S, EB12B, EB1220BL, EB1224, EB1226HL, EB1230H, BCH1220, EB1230HL, EB1230X, EB1233X, EB1412S, EB1414S, EB1414, EB14B, EB1424, EB1426H, EB1430H, EB1430X, EB1433X, BCH1420, EB1812S, EB1814SL, EB18B, EB1820, EB1820L, EB1824L, EB1826HL, EB1830H, EB1830HL, EB1830X, EB1833X, BCH1820.

What does a red LED flashing 1 second on / 0.5 second off mean?

This flashing indicates the battery is overheated. Let it cool down before recharging. Charging will start automatically when the temperature returns to normal.

Can I use the charger outdoors?

No, the charger must only be used indoors, in a dry and well-ventilated place. Do not expose it to rain or humidity.

How long does it take to fully charge a battery?

Charging time varies from 30 to 70 minutes depending on the battery type and capacity (see table in the manual). For example, a 1.2 Ah battery charges in 30 min, a 3.3 Ah battery in 70 min at 20 °C.

What should I do if the battery does not charge?

Check that the battery is correctly inserted and that polarity is respected. Make sure the ambient temperature is between 0 and 40 °C. If the LED does not light up, check the mains socket. If the problem persists, contact an authorized repair center.

Can I recharge a battery immediately after using it?

It is recommended to let the battery cool down for a few minutes before recharging, as a hot battery can reduce its lifespan. The charger detects overheating and waits for the battery to cool down.

How to maintain the UC18YGH charger?

Clean the exterior with a dry or slightly damp cloth (soapy water). Do not use harsh solvents. Store the charger in a dry place, away from dust and out of reach of children.

Where can I find spare parts or have the charger repaired?

Use only genuine HiKOKI parts. Any repair must be carried out by an authorized repairer. Consult the list of authorized centers on the HiKOKI website or contact after-sales service.

The red LED flashes rapidly (0.5 s on, 0.5 s off): what should I do?

This flashing means the battery is in standby mode. Wait a few seconds; if the battery is inserted, charging should start automatically. If it does not start, remove and reinsert the battery after 3 seconds.

8. 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.

1. Do not allow foreign matter to enter the hole for connecting the rechargeable battery.
2. Never disassemble the rechargeable battery or charger.
3. 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.

1. Do not dispose of the battery in fire.
   If the battery is burnt, it may explode.
2. Using an exhausted battery will damage the charger.
3. 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.
4. Do not insert objects into the air ventilation slots of the charger.

Inserting metal objects or flammable into the charger air ventilation slots will result in an electrical shock hazard or damage to the charger.

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).

1. Insert the battery into the charger.

Firmly insert the battery into the charger till it contacts the bottom of the charger and checking the polarities as shown in Fig. 1.

CAUTION

☐ If the batteries are inserted in the reverse direction, not only recharging will become impossible, but it may also cause problems in the charger such as a deformed recharging terminal.

3. Charging

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.

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

1. Disconnect the charger's power cord from the receptacle.

2. Hold the charger firmly 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 first 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.

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 (off for 0.5 seconds). In such a case, first let the battery cool, then start charging.

○ Since the built-in micro computer takes about 3 seconds to confirm that the battery being charged with UC18YGH 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.

NOTE

Due to HiKOKI's continuing program of research and development, the specifications herein are subject to change without prior notice.
