(2) Regarding the temperature of the rechargeable
battery.
The temperatures for rechargeable batteries are as
shown in Table 1.
4. Disconnect the charger's power cord from the
receptacle.
5. Hold the charger firmly and pull out the battery.
CAUTION (UC18YGH)
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 for 1 second,
does not light for 0.5 seconds (off for 0.5 seconds). In
such a case, first let the battery cool, then start
charging.
Since the built-in micro computer takes about 3
seconds to confirm that the battery being charged
with UC18YGH 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.
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.
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.

bit. (Fig. 4)
(1) Pull the guide sleeve away from front of the tool.
(2) Insert the bit into the hexagonal hole in the anvil.
(3) Release the guide sleeve 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.

HOW TO USE

CAUTION:
When using the light equipped hook, pay sufficient
attention so that the main equipment does not fall. If
the tool falls, there is a risk of accident.
Do not attach the tip tool except phillips bit to the tool
main unit when carrying the tool main unit with the
light equipped hook suspended from a waist belt.
Injury may result if you carry the equipment
suspended from the waist belt with sharp tipped
components such as drill bit attached.
1. Using the light equipped hook
The light equipped hook can be installed on the right
or left side and the angle can be adjusted in 5 steps
between 0° and 80°.
(1) Operating the hook
(a) Pull out the hook toward you in the direction of
arrow (A) and turn in the direction of arrow (B).
(Fig. 5)
(b) The angle can be adjusted in 5 steps (0°, 20°, 40°,
60°, 80°).
Adjust the angle of the hook to the desired position
for use.
(2) Switching the hook position
