Prior To Operation - Hitachi CR 18DV Bedienungsanleitung

English
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 short 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 been 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 batetery 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.
When the pilot lamp flickers 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 confirm that the battery being charged
with UC24YFA 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. Mounting the blade
This unit employs a detachable mechanism that
enables mounting and removal of saw blades
without the use of a wrench or other tools.
(1) Turn on and off the switching trigger several times
so that the holder sleeve can jump out of the front
cover completely. Thereafter, turn off the switch
and remove the battery. (Fig. 4)
CAUTION
Be absolutely sure to keep the switch turned off
and the battery removed to prevent any accident.
(2) Turn the holder sleeve in the direction of the arrow
mark shown in Fig. 5 marked on the holder sleeve.
If you turn the holder sleeve halfway you will be
able to secure it automatically. (Fig. 5)
(3) Insert the saw blade all the way into the small slit
of the plunger tip. You can mount this blade either
in the upward or downward direction. (Fig. 6,
Fig. 7)
(4) Pull the holder sleeve back slightly in the direction
9
of the arrow mark shown in Fig. 8 (in the direction
opposite to the arrow marked on the holder sleeve).
When you do this, the spring force will return the
holder sleeve to the correct position automatically.
There is no need to fasten the holder sleeve at this
time. (Fig. 8)
(5) Pull the back of the saw blade two or three times
by hand and check that the blade is securely
mounted. When pulling the blade, you will know
it is properly mounted if it clicks and the holder
sleeve moves slightly. (Fig. 9)
CAUTION
When pulling the saw blade, be absolutely sure to
pull it from the back. Pulling other parts of the blade
will result in an injury.
2. Dismounting the blade
(1) Turn on and off the switching trigger several times
so that the holder sleeve can jump out of the front
cover completely. Thereafter, turn off the switch
and remove the battery. (Fig. 4)
CAUTION
Be absolutely sure to keep the switch turned off
and the battery removed to prevent any accident.
(2) After you have turned the holder sleeve in the
direction of the
Fig. 5 and secured it, turn the blade so it faces
downward. The blade should fall out by itself. If
the blade doesn't fall out, pull it out by hand.
CAUTION
Never touch the saw blade immediately after use.
The metal is hot and can easily burn your skin.
WHEN THE BLADE IS BROKEN
Even when the saw blade is broken and remains
inside the small slit of the plunger, it should fall
out if you turn the holder sleeve in the direction
of the arrow mark, secure the holder sleeve, and
face the blade downward. If it doesn't fall out itself,
take it out using the procedures explained below.
(1) If a part of the broken saw blade is sticking out
of the small slit of the plunger, pull out the protruding
part and take the blade out.
(2) If the broken saw blade is hidden inside the small
slit, hook the broken blade using a tip of another
saw blade and take it out. (Fig. 10)
MAINTENANCE AND INSPECTION OF SAW BLADE
MOUNT
(1) After use, blow away sawdust, earth, sand, moisture,
etc., with air or brush them away with a brush, etc.,
to ensure that the blade mount can function
smoothly.
(2) Periodically lubricate the saw blade mount with
machine oil through the small slit at a state where
the holder sleeve is turned in the direction of the
arrow mark shown in Fig. 5. (Fig. 11)
NOTE:
If the saw blade mount is used without proper
cleaning and lubrication, the rotation of the holder
sleeve may be hampered by sawdust and particles
of dust, disabling you to remove the saw blade with
your fingers.
In such a case, hold the periphery of the holder
sleeve lightly using a pair of pliers and the like, and
turn the holder sleeve to left and right little by little.
