Mounting And Operation; Maintenance And Inspection - Hitachi CE 18DSL Bedienungsanleitung

English
NOTE
The recharging time may vary according to the ambient
temperature and power source voltage.
<UC18YML2>
Especially, using a DC 12 V in-car power source may
require longer recharging time at high temperatures.
CAUTION
When the battery charger has been continuously 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.
4. Disconnect the charger's power cord from the
receptacle or cigarette lighter socket.
5. Hold the charger fi rmly and pull out the battery.
NOTE
Be sure to pull out the battery from the charger after use,
and then keep it.
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 pilot lamp of the charger lights up green or lights
for 1 second, does not light for 0.5 seconds (off for
0.5 seconds). In such a case, fi rst let the battery cool,
then start charging.
○ When the pilot lamp fl ickers in red (at 0.2-seconds
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
charger 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.
○ Check the voltage of the in-car power source when
the pilot lamp fl ickers in green (every 0.2 seconds)
continuously. (UC18YML2)
If the voltage is 12 V or lower, it indicates that the car
battery has weakened and cannot be charged.
○ If the pilot lamp does not blink in red (every second) even
though the charger cord or cigarette lighter connecting
plug is connected to the power, it indicates that the
protection circuit of the charger may be activated.
Remove the cord or plug from the power and then connect
it again after 30 seconds or so. If this does not cause the
pilot lamp to blink in red (every second), please take the
charger to the Hitachi Authorized Service Center.

Adjust the horizontal gap between the shearing blades (A
in Fig. 3) at approximately 1/10 the steel plate thickness
to be sheared, according to the following procedures.
(1) Loosen the hexagonal socket bolts ⓒ fastening the
stationary blade. Loosen the M4 lock nut ⓓ, and
push back the M4 slotted set screws ⓔ slightly.
(2) From the supplied thickness gauges ⓕ, select one
that is 1/10 the thickness of the panel to be cut.
Thickness of each thickness gauge ⓕ is marked
thereon. Insert the gauge ⓕ in between the blades,
then tighten the hexagonal socket bolts ⓒ very
loosely. Next, use a screwdriver to turn the M4
slotted set screws ⓔ to position the stationary blade
until it hits the thickness gauge ⓕ.
(3) If the space between blades is larger than the
thickness of the panel to be cut, there will be burrs for
a less than clean cut.
If the space between blades is too narrow, cutting
speed will be aff ected. For cutting in a curved line,
making the space a little bigger will make the cutting
easier.
(4) After adjustment, tighten the M4 nuts ⓓ securely so
they will not loosen during operation.
(5) Securely tighten the hexagonal socket bolts ⓒ
fastening the stationary blade.
*2. Cutting (see Fig. 6)
CAUTION
○ Do not attempt to cut panels of thicknesses that are
beyond the capability of the hand shear. Doing so will
result in premature breakage of the hand shear.
○ Perform the cutting operation only after the panel is
fi xed securely.
When cutting thin panels, level the unit horizontally.
To facilitate smooth cutting of thick panels, if the cut-
off side goes toward the left, raise the rear of the unit
slightly. And if the cut-off side goes toward the right,
lower the rear of the unit slightly.

MAINTENANCE AND INSPECTION

1. Inspecting the blade
Using a worn or chipped blade will put an excessive
burden on the motor and aff ect work performance.
Therefore, always use a well-cutting blade.
2. Inspecting the mounting screws
Regularly inspect all mounting screws and ensure that
they are properly tightened. Should any of the screws be
loose, retighten them immediately. Failure to do so could
result in serious hazard.
3. Maintenance of the motor
The motor unit winding is the very "heart" of the power
tool. Exercise due care to ensure the winding does not
become damaged and/or wet with oil or water.
4. Blade replacement (see Fig. 7)
The hand shear uses disposable blades. Each blade has
8 cutting edges ⓖ. After a cutting edge cuts 400 meters
of panel, cutting performance will fall. Then use another
cutting edge. After all 8 cutting edges ⓖ are used and
worn, replace the blade.
5. Inspecting the carbon brushes (see Fig. 8)
The motor employs carbon brushes which are
consumable parts. Since and excessively worn carbon
brush can result in motor trouble, replace the carbon
brush with new ones when it becomes worn to or near
the "wear limit" ⓗ. In addition, always keep carbon
brushes clean and ensure that they slide freely whithin
the brush holders.
NOTE
When replacing the carbon brush with a new one, be
sure to use the Hitachi Carbon Brush Code No. 999054.
