(2) Regarding recharging time

Table 2

shows the recharging time required according to the type of battery.

4. Disconnect the charger power cord from the

receptacle.

5. 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

䡬

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.

䡬

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.

䡬

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.

䡬

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.

䡬

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.

䡬

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.

䡬

Leave 5 minutes between charging batteries as the
charger may overheat leading to malfunction.

䡬

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

䡬

Charging times may be longer depending on the
surrounding temperature and battery conditions.

䡬

Charge time lamp indications are only a guide, and
may vary depending on the surrounding temperature
and battery conditions.

䡬

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.
