(2) Regarding the temperatures of the rechargeable
battery
The temperatures for rechargeable batteries are as
shown in the table below, and batteries that have
become hot should be cooled for a while before
being recharged.
Table 2 Recharging ranges of batteries
4. Disconnect the charger’s power cord from the
receptacle
5. 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.
CAUTION
䡬
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, first let the battery cool, then start
charging.
䡬
When the pilot lamp flikers 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.
䡬
Since the built-in micro computer takes about 3
seconds to confirm that the battery being charged
with UC18YRL 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.
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. Preparing and checking the work environment
Make sure that the work site meets all the conditions
laid forth in the precautions.
2. Checking the battery
Make sure that the battery is installed firmly. If it is at
all loose it could come off and cause an accident.
3. Installing the bit (Impact driver)
Always follow the following procedure to install driver
bit (Fig. 2).
(1) Pull the guide sleeve
7
away from front of the tool.
(2) Insert the bit
9
into the hexagonal hole in the anvil
8
.
(3) Release the guide sleeve
7
and it returns to its original
position.
CAUTION
If the guide sleeve does not return to its original
position, then the bit is not installed properly.
4. Selecting the socket matched to the bolt
(Impact wrench)
Be sure to use a socket which is matched to the bolt
to be tightened. Using an improper socket will not
only result in insufficient tightening but also in
damage to the socket or nut.
A worn or deformed hex. or square-holed socket will
