Operational Cautions; Maintenance And Inspection - Hitachi WM 10DBL Instrucciones De Manejo

English
NOTE
If the battery has not been used for a long time, it
may take longer to charge it because of self-discharge.
Lifetime of battery
When only one or less indicator lamp lights after correct
charging, the battery capacity is 50% or less.
This means the lifetime of the battery has expired. Please
purchase a new one.
How to make the batteries perform longer.
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.
Operation in a low temperature environment (less than 0°C)
When BCL1030A is used in a low temperature environment,
the motor may stop even if the remaining battery level is
high enough. This is just a temporary phenomenon. The
battery can be used as usual when warmed up.

OPERATIONAL CAUTIONS

1. Continuous operation
When you perform the striking operation
continuously, the temperature protection circuit may
be activated early. (Refer to "2. Characteristics of
Electronic Pulse Driver" on page 9.)
When the activated temperature protection circuit
stops the tool, the LED light flashes to indicate that
the tool is heated to high temperature. The LED light
goes off automatically after approx. 30 seconds.
When you perform continuous operation, allow the
tool to rest for around 15 minutes at a replacement of
rechargeable battery.
NOTE
When the tool is stopped by the activated temperature
protection circuit, allow the tool to cool sufficiently.
You can use the tool again when it cools down.
While the tool is not cooled sufficiently, it cannot
start up by turning the switch to on. The LED light
flashes while the switch is turned on. Please wait
until the tool cools down sufficiently.
Do not touch the nose part of the tool during
continuous operation. It is heated to high temperature.
2. Cautions on use of the speed control switch
This switch has a built-in, electronic circuit which
steplessly varies the rotation speed. Consequently, when
the switch trigger is pulled only slightly (low speed
rotation) and the motor is stopped while continuously
driving in screws, the components of the electronic
circuit parts may overheat and be damaged.
3. Holding the tool and applying the pressing force
Make sure to hold the tool securely with your both hands,
and keep the tool straight to a screw or bolt. There is no
need to press the tool excessively against materials.
Be careful not to apply excessive pressing/prying
force to the tool. It may damage the tool.

MAINTENANCE AND INSPECTION

1. Inspecting the tool
Since use of a dull tool will degrade efficiency and
cause possible motor malfunction, sharpen or replace
the tool as soon as abrasion is noted.
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 may 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. Cleaning of the outside
When the tool is stained, wipe with a soft dry cloth or a
cloth moistened with soapy water. Do not use chloric
solvents, gasoline or paint thinner, as they melt plastics.
5. Storage
Store the tool in a place in which the temperature is
less than 40°C, and out of reach of children.
NOTE
Make sure that the battery is fully charged when
stored for a long period (3 months or more). The
battery with smaller capacity may not be able to be
charged when used, if stored for a long period.
6. Service parts list
CAUTION
Repair, modification and inspection of Hitachi Power
Tools must be carried out by a Hitachi Authorized
Service Center.
This Parts List will be helpful if presented with the
tool to the Hitachi Authorized Service Center when
requesting repair or other maintenance.
In the operation and maintenance of power tools, the
safety regulations and standards prescribed in each
country must be observed.
MODIFICATIONS
Hitachi Power Tools are constantly being improved
and modified to incorporate the latest technological
advancements.
Accordingly, some parts may be changed without
prior notice.
Important notice on the batteries for the Hitachi
cordless power tools
Please always use one of our designated genuine
batteries. We cannot guarantee the safety and
performance of our cordless power tool when
used with batteries other than these designated
by us, or when the battery is disassembled and
modified (such as disassembly and replacement
of cells or other internal parts).
NOTE
Due to HITACHI's continuing program of reserch and
development, the specifications herein are subject to
change without prior notice.
