Mounting And Operation; Maintenance And Inspection - Hitachi G 18DBBL 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.

*1 WARNING
Before use, be sure to tighten the wheel nut with the
included wrench.
Failure to tighten could result in the wheel nut
loosening when the brake is activated during a stop.
NOTE
The wheel washer is specifi cally for this product. Do
not use it for any other product.
*2 About the mode change function
With the storage battery installed to the main unit and the
unit switched on, pressing the mode change switch will
switch the operation mode to auto mode. While in Auto
mode, the Auto mode display lamp will remain lit.
○ With Auto mode, you can lower noise and vibration by
lowering the maximum number of revolutions while in a
no-load state.
While in Auto mode, the number of revolutions will be
raised if the load becomes greater during operation.
On the other hand, the number of revolutions will be
lowered if the load decreases during operation. (Table 3,
page 10)
<G18DBBVL>
With the G18DBBVL, pressing the mode change switch
will change the operating mode back and forth between
Auto mode and Transmission mode.
With Transmission mode, the grinder's number of
revolutions can be set at one of six stages.
When operating in Transmission mode, the set number
of revolutions will be maintained regardless of changes
in load.
Set the mode and dial according to work application.
(Table 3, page 10)

MAINTENANCE AND INSPECTION

1. Inspecting the depressed center wheel
Ensure that the depressed center wheel is free of cracks
and surface defects.
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.
232
4. Cleaning on the outside
When the cordless disc grinder is stained, wipe with a
232
soft dry cloth or a cloth moistened with soapy water. Do
not use chloric solvents, gasoline or paint thinner, for
232
they melt plastics.
5. Cleaning the fi lter
232
After use, detach the fi lter and remove any grime or dust
from the screen with an airgun or other tool. (Fig. 12)
232
NOTE
○ To clear the unit of grime or dust, periodically run
233
the motor in a no-load state and blow dry air into the
233
ventilation hole with the fi lter removed.
Accumulation of grime or dust accumulates in the motor
233
can cause damage.
233
○ After cleaning, make sure to securely attach the fi lter.
