CHARGING
Before using the power tool, charge the battery as
follows.
1. Connect the charger’s power cord to the receptacle.
2. Insert the battery into the charger.
Insert the battery firmly while observing its direction,
until it contacts the bottom of the charger (See
Figs.
1, 2, 3 and 4
)(the battery set lamp lights up).
Inserting the battery will turn on the charger (the
pilot lamp lights up).
CAUTION:
If the battery set lamp does not light up, pull out
the power cord from the receptacle and check the
battery mounting condition.
CAUTION:
If the battery is heated due to direct sunlight,
etc., just after operation, the charger pilot lamp
may not light. At that time cool the battery first,
then start charging.

Regarding recharging time
Table 1
shows the recharging time required
according to the type of battery.
NOTE:
With the above recharging time as a guide, remove the battery from the charger. The battery set lamp
goes off when the battery is removed.
When the battery temperature is low (below 0 °C) or supply voltage is low, the battery capacity after a
charge will become smaller.
If you feel the operating time of the tool is short, recharge the battery longer than the above time.
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.
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. Disconnect the charger’s power cord from the
receptacle.
4. Hold the battery firmly and pull out the charger.
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.
