Prior To Operation - Hitachi WR 36DA Handling Instructions Manual

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.
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
charge indicator lamp of the charger lights for 0.3 seconds, does not light for 0.3
seconds (off for 0.3 seconds). In such a case, fi rst let the battery cool, then start
charging.
○ When the charge indicator lamp fl ickers (at 0.2-second intervals), check for and
take out any foreign objects in the charger's battery connector. 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 UC18YSL3 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. 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 fi rmly. If it is at all loose it could come off and cause
an accident.
3. Selecting the socket matched to the bolt
Be sure to use a socket which is matched to the bolt to be tightened. Using an improper
socket will not only result in insuffi cient tightening but also in damage to the socket or nut.
A worn or deformed hex. or square-holed socket will not give an adequate tightness for
fi tting to the nut or anvil, consequently resulting in loss of tightening torque.
Pay attention to wear of socket hole, and replace
before further wear has developed.
4. Installing a socket
Select the socket to be used.
● Pin, O-ring type
(1) Slide the O-ring out of the groove, then align the hole
of the socket with the hole of the anvil and insert the
anvil into the socket. (Fig. 6)
