Prior To Operation - Hitachi C 18DBAL Safety Instructions And Instruction 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
● When the battery charger has been continuosly
used, the battery charger will be heated, thus
constituting the cause of the failures. Once the
charging has been completed, give 15 minutes
rest until the next charging.
● 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
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.

PRIOR TO OPERATION

CAUTION
To avoid serious accident, ensure the switch is in
the OFF position, and pull out the battery.
1. Check the work area environment
Check the work area to make sure that it is clear of
debris and clutter.
Clear the area of unnecessary personnel. Ensure that
lighting and ventilation is adequate.
2. Mounting the Saw Blade (Fig. 8)
WARNING
If the left-hand bolt is worked using other tools
than the provided hex. wrench, excessive
tightening and insuffi cient tightening may take
place, resulting in injury.
(1) Thoroughly remove any sawdust which has
accumulated on the spindle, bolt and washers.
(2) Apply quality machine oil to the surfaces of washers
(B) and (A) which come into contact with the blade.
(3) As shown in Fig. 8, one side of the saw blade should
be fi tted to the projecting center of washer (A) which
matches the blade's inner diameter, and the other
side to the concave side of washer (B).
(4) To ensure that the saw blade rotates in the correct
direction, make sure the arrow on the saw blade
points in the same direction indicated by the arrow on
the saw cover.
(5) Using the fi ngers, tighten the left-hand bolt securing
the saw blade as much as possible. Then press the
lock button, lock the spindle, and fully tighten the left-
hand bolt with the hex. wrench.
CAUTION
After mounting the saw blade, reconfi rm that the
lock button is fi rmly secured in the prescribed
position.
3. Dismounting the saw blade
CAUTION
Never touch the saw blade immediately after use.
The metal is hot and can easily burn your skin.
(1) Set the cutting volume at maximum, and place the
Circular Saw as shown in Fig. 9.
