(2) Regarding recharging time
Depending on the combination of the charger and
batteries, the charging time will become as shown
in Table 2.

NOTE:
The charging time may vary according to embient
temperature and power source voltage.
4. Disconnect the charger's power plug from the
receptacle on completion of recharging.
5. Hold the charger firmly and pull out the battery.
NOTE:
After charging, pull out batteries from the charger
first, and then keep the batteries properly.
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 capacity 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.

Approx. 70 min.
Malfunction in the battery or the charger
The battery temperature is high, making
recharging impossible.
(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 has been heated just after operation
(or due to sunlight, etc.), the charger's pilot lamp
will not light in red. In such a case, first let the
battery cool, then start charging.
When the pilot lamp frickers in red quickly (at 0.2-
second intervals), check for and take out any foreign
objects in the charger's battery installation hole. 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 UC14YFA 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.
PRIOR TO OPERATION
1. Setting up and checking the work environment
Check if the work environment is suitable by
following the precautions.
2. Confirm that the battery is mounted correctly
3. Setting the forward/reverse switching button
(1) Push the forward/reverse switching button from the
right as shown in Fig. 4-1. Cutting is possible in
the
position (Fig. 4-1).
(2) By setting the forward/reverse switching button in
the
(central) position as shown in Fig. 4-2, the
motor will not operate even if the trigger switch
is pulled. When carrying or storing the main unit
or when stopping operations, set the forward/reverse
switching button to the
English
position (Fig. 4-2).
