NOTE
The recharging time may vary according to temperature
and power source voltage.
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.
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 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 (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 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.
○ If the pilot lamp does not blink in red (every second)
even though the charger cord 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.
REGARDING ENVIRONMENT AND
CONDITIONS OF USE
This tool operates on oil pressure.
When used during the winter season or in cold conditions
the hydraulic oil's viscosity will excessively rise to dull the
tool's operation.
In such cases, run the tool through a warm-up operation
prior to use.
How to run a warm-up operation
Without setting up a rebar, switch on the tool and let it
continuously run for 30 to 60 seconds.
WARNING
Do not place your hands in the vicinity of the piston
during warm-up operation.
Depending on the environment and conditions of use, the
hydraulics may heat up (over 50°C). This can lower the
viscosity of the hydraulic oil and reduce its cutting power.
If this occurs, allow the tool to cool down and then resume
operation.
