NOTE: When standby for cooling battery, UC36YRL cools the overheated battery by cooling fan.
(2) Regarding the temperatures of the rechargeable battery
The temperatures for rechargeable batteries are as
shown in Table 2, and batteries that have become hot
should be cooled for a while before being recharged.

(3) Regarding recharging time
Depending on the type of the battery, the charging time
will become as shown in Table 3.

NOTE: The charging time may vary according to ambient
temperature and power source voltage.
4. Disconnect the charger's power cord from the
receptacle
5. Hold the charger fi rmly and pull out the battery
NOTE:
Be sure to pull out the battery from the charger after use,
and then keep it.
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
pilot lamp of the charger lights up green. In such a case,
fi rst let the battery cool, then start charging.
○ When the pilot lamp fl ickers 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 confi rm 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.

Recharging time
Approx. 60 min.
Approx. 80 min.
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 fi rst 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.

PRIOR TO OPERATION

1. Mounting the drill bit (Fig. 4, 5)
CAUTION
To prevent accidents, make sure to turn the switch off .
NOTE:
When using tools such as drill bits, etc., make sure to use
the genuine parts designated by our company.
(1) Clean the shank portion of the drill bit.
(2) Insert the drill bit in a twisting manner into the tool holder
until it latches itself. (Fig. 4)
(3) Check the latching by pulling on the drill bit.
(4) To remove the drill bit, fully pull the grip in the direction of
the arrow and pull out the drill bit.
2. Confi rm that the battery is mounted correctly
3. Installation of dust cup or dust collector (B)
(Optional accessories) (Fig. 6, Fig. 7)
When using a rotary hammer for upward drilling
operations attach a dust cup or a dust collector (B) to
collect dust or particles for easy operation.
