Maintenance And Inspection - Hitachi Koki NR 1890DBCL Instrucciones De Manejo

English
2 Securely hold the main unit and remove the screw using
a screwdriver. (See Fig. 18)
3 Remove the hook and hook plate. (See Fig. 19)
4 Install the hook on the other side and securely fasten
with screw. (See Fig. 20)
NOTE
Hook can be used as a hanger.
4. Clearing a jam
If nails are jammed in fi ring head, remove it, and adjust
the nailing in the following order.
CAUTION
Remove the battery from the Nailer.
1 Remove the battery from the Nailer.
2 Remove all nails.
3 Remove the M5 bolts with wrench. (See Fig. 21)
4 Pull magazine away from the fi ring head, and clear jam.
(See Fig. 22)
CAUTION
○ NEVER hit the driver blade.
○ NEVER point the tool at yourself or another person, to
avoid risk of injury by mis-fi ring.
Even if the battery is removed from the nailer, there is still
energy of compressed air remaining inside.
5 Attach the magazine to the injector and tighten with the
M5 bolt.
NOTE
In case of frequent jam, contact a Hitachi authorized
service center.

MAINTENANCE AND INSPECTION

CAUTION
Be sure to remove all remaining fasteners and battery
from the nailer before maintenance and inspection.
1. Inspecting the magazine
1 Remove battery from the Nailer.
2 Clean the magazine. Remove dust and wooden
chips which may have accumulated in the magazine.
CAUTION
Check that the nail feeder slides smoothly by pulling it
with fi nger.
If not smooth, nails can be driven at an irregular angle
and hurt someone.
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. Cleaning on the outside
When the power 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, for they melt plastics.
5. Storage
Store the power tool in a place in which the temperature
is less than 40°C and out of reach of children.
NOTE
Storing lithium-ion batteries.
Make sure the lithium-ion batteries have been fully
charged before storing them.
Prolonged storage (3 months or more) of batteries with
a low charge may result in performance deterioration,
signifi cantly reducing battery usage time or rendering
the batteries incapable of holding a charge.
However, signifi cantly reduced battery usage time may
be recovered by repeatedly charging and using the
batteries two to fi ve times.
If the battery usage time is extremely short despite
repeated charging and use, consider the batteries dead
and purchase new batteries.
CAUTION
In the operation and maintenance of power tools, the
safety regulations and standards prescribed in each
country must be observed.
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 modifi ed (such as
disassembly and replacement of cells or other internal
parts).
GUARANTEE
We guarantee Hitachi Power Tools in accordance with
statutory/country specifi c regulation. This guarantee does
not cover defects or damage due to misuse, abuse, or
normal wear and tear. In case of complaint, please send
the Power Tool, undismantled, with the GUARANTEE
CERTIFICATE found at the end of this Handling instruction,
to a Hitachi Authorized Service Center.
Noise Information
Noise characteristic values in accordance with EN 792-13:
The typical A-weighted single-event sound power level
The typical A-weighted single-event emission sound
pressure level at work station
Uncertainty KpA: 3 dB
These values are tool-related characteristic values and
do not represent the noise development at the point of
use. Noise development at the point of use will for example
depend on the working environment, the workpiece, the
workpiece support and the number of driving operations,
etc.
Depending on the conditions at the workplace and the form
of the workpiece, individual noise attenuation measures
may need to be carried out, such as placing workpieces on
sound-damping supports, preventing workpiece vibration by
means of clamping or covering, etc.
In special cases it is necessary to wear hearing protection
equipment.
Vibration Information
The typical vibration characteristic value in accordance with
EN 792-13: 4.6 m/s
2
Uncertainty K = 1.5 m/s
This values is a tool-related characteristic value and
does not represent the infl uence to the hand-arm-system
when using the tool. An infl uence to the hand-arm-system
when using the tool will for example depend on the gripping
force, the contact pressure force, the working direction, the
adjustment of energy supply, the workpiece, the wrokpiece
support.
The declared vibration total value has been measured in
accordance with a standard test method and may be used
for comparing one tool with another.
It may also be used in a preliminary assessment of exposure.
WARNING
○ The vibration emission during actual use of the power
tool can diff er from the declared total value depending in
the ways in which the tool is used.
