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.

Firmly insert the battery into the charger until the line is visible, as shown in Fig. 1.

3. Charging

When inserting a battery in the charger, the charge status lamp will light up continuously in red. When the battery becomes fully recharged, the charge status lamp will blink in red. (At 1-second intervals.) (See Table 1)

(1) Lamp indication

The indications of the lamp will be as shown in Table 1, according to the condition of the charger or the rechargeable battery.

Table 1

Indications of the lamp
Charge status lamp(red)	Before charging	Blinks	Lights for 0.5 seconds. Does not light for 0.5 seconds. (off for 0.5 seconds)
	While charging	Lights	Lights continuously
	Charging complete	Blinks	Lights for 0.5 seconds. Does not light for 0.5 seconds. (off for 0.5 seconds)
	Charging impossible	Flickers	Lights for 0.1 seconds. Does not light for 0.1 seconds. (off for 0.1 seconds)	Malfunction in the battery or the charger
Overheat lamp(green)	Overheat standby	Lights	Lights continuously	Battery overheated. Unable to charge.(Charging will commence when battery cools)

NOTE: When standby for cooling battery, UC36YRL cools the overheated battery by cooling fan.

(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

Rechargeable batteries	Temperatures at which the battery can be recharged
BSL2530, BSL3626	0°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	Li-ion BATTERY
	2.6 Ah		3.0 Ah
25.2 V	—	—	BSL2530(14 cells)	60 min.
36 V	BSL3626(20 cells)	80 min.	—	—

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 overheat lamp of the charger lights up green. In such a case, first let the battery cool, then start charging.
When the charge status lamp flickers in red (at 0.2-seconds intervals), check for and take out any foreign objects in the charger's battery connector. If there are no foreign objects, it is probable that the battery or charger is malfunctioning. Take it to your authorized Service Center.
○ Since the built-in micro computer takes about 3 seconds to confirm that the battery being charged with UC36YRL 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.

1. 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.

1. Store idle charger

When not in use, the charger should be stored in dry, high or locked-up place — out of reach of children.
