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 charge status lamp will blink in red (At 1-second intervals).
2. Insert the battery into the charger. Insert the battery into the charger as shown in Fig. 1. When the battery is pushed all the way to the bottom, charging starts, and the charge time lamp lights red, orange, or green according to the remaining charging time.

3. Charging

(1) Lamp indications

This charger is equipped with a charge time lamp that indicates remaining charging time, and a charge status lamp that indicates battery status as shown in Table 1.

(a) Charging time

After charging commences, the charge time lamp lights red indicating 30 minutes, orange indicating 20 minutes, and green indicating 5 minutes until completion. When the battery is fully charged, the charge status lamp lights green, and the buzzer sounds continuously for 6 seconds.

(b) Overheat standby

When the battery is overheated, it cannot be charged, and the charge time lamp flashes red (in 0.6 second intervals). Leave the battery inserted in the charger, and charging will commence when the battery cools down.

(c) Charging impossible

When there is a malfunction with the battery or charger, the charge status lamp flashes orange rapidly (in 0.2 second intervals), and the buzzer sounds intermittently for 5 seconds.

: Ni-MH batteries

1. Disconnect the charger power cord from the receptacle.

2. Hold the charger tight and pull out the battery.

Revitalizing the battery (trickle recharge)

A new battery or a battery that has not been used for extensive periods may not charge completely due to internal chemicals being inert.

Leave the battery inserted in the charger for 8 to 12 hours after charging is complete. The charger automatically 'revitalizes' the battery by trickle recharging.

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

○Repair is required if the receptacle is not secured properly or the power cord does not stay in the receptacle. Consult your electrician. Using the charger in this condition may lead to fire.

Insert the battery into the charger with the model name facing left (toward the lamp). If the battery is inserted in the reverse direction, not only will recharging be impossible, but also the terminals may be damaged leading to malfunction.

If the charge status lamp is flashing orange rapidly (in 0.2 second intervals) and the buzzer sounds intermittently for 5 seconds, check that the hole for connecting the battery is not obstructed. Remove any obstructions. If no obstructions are found, the battery or charger may be malfunctioned. Return both to your place of purchase.

If the charge time lamp does not light when the power cord is connected to the receptacle, disconnect the power cord, and check that the battery is attached correctly.
The battery retains heat when used or left for prolonged periods in direct sunlight. In this state, the charge time lamp flashes red, and the battery cannot be charged immediately. Leave the battery inserted in the charger, and charging will commence when the battery cools down.
If the lamp goes out while charging, disconnect the power cord, and leave for 3 to 5 minutes before reconnecting. If the problem persists, call for repairs.
Leave 5 minutes between charging batteries as the charger may overheat leading to malfunction.
The battery life is finished if it can only be used for short periods even when fully charged. Purchase a new battery. Continuing to use a depleted battery may cause the charger to malfunction.

NOTE

Charging times may be longer depending on the surrounding temperature and battery conditions.
Charge time lamp indications are only a guide, and may vary depending on the surrounding temperature and battery conditions.
Remove the battery from the charger when not in use.

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 on 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, as 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.
