Basic Functions; Battery Removal/Installation - Hitachi GP 10DL Bedienungsanleitung

OPTIONAL ACCESSORIES (sold separately)
1. Battery (BCL1015)
Optional accessories are subject to change without notice.
APPLICATIONS
○ Making wood carved handicrafts and precious metal
ornaments
○ Engraving and sculpting glass and ceramics
○ Grinding and polishing steel and stone

BASIC FUNCTIONS

1. Low battery warning lamp (Fig. 1)
To check the remaining battery power, operate the
grinder unloaded.
If the remaining battery power is low, the warning lamp
(red LED) will light. If the lamp lights, charge the battery
without delay.
NOTE
○ The low battery warning lamp may be aff ected by the
ambient temperature or battery characteristics. Use
the lamp as a guide for when to charge the battery.
○ The low battery warning lamp may light during
operation of the grinder. This is due to a temporary
drop in the battery voltage, and not to low battery
power.
○ When checking the remaining battery power, be sure
to operate the grinder in an unloaded condition.
2. Switch dial
The switch dial also serves as the start-up switch and
the speed dial. When the dial is rotated from [0] to a
higher number, the grinder switches on and gradually
builds up speed. At the same time, the LED lamp lights
and illuminates the tip of the grinder.
When the dial is returned to [0], the grinder switches off
and rotation stops.
For safety reasons, the grinder will not start up if the
battery is inserted while the switch is at any position
other than [0].
To switch the grinder on at such time, return the dial to
[0] and then rotate it to a higher number.
The approximate relationship between the numbers on
the switch dial and the rotation speed is shown in the
graph in Fig. 2.

BATTERY REMOVAL/INSTALLATION

1. Battery removal
Hold the handle tightly and push the battery latch to
remove the battery (see Figs. 3 and 4).
CAUTION
Never short-circuit the battery.
2. Battery installation
Insert the battery while observing its polarities (see
Fig. 4).
CHARGING
Before using the power tool, charge the battery as follows.
1. Connect the charger power cord to the receptacle
2. Insert the battery in the charger
Position the battery so that the nameplate faces toward
the nameplate of the charger and press in the battery
until it comes into contact with the bottom plate (See
Fig. 5).
Inserting the battery will turn on the charger (the pilot
lamp lights up).
CAUTION
If the pilot lamp does not light up, pull out the power
cord from the receptacle and check the battery
mounting condition.
The pilot lamp goes off to indicate that the battery is
fully charged.
CAUTION
If the battery is heated due to direct sunlight, etc.,
just after operation, the charger pilot lamp may not
light. At that time cool the battery fi rst, then start
charging.
○ Regarding recharging time
Table 1 shows the recharging time required according
to the type of battery.

voltage (V)
10.8 V BCL1015
NOTE
The recharging time may vary according to the ambient
temperature.
3. Disconnect the charger's power cord from the
receptacle
4. 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.
How to make the batteries perform longer
(1) Recharge the batteries before they become completely
exhausted.
When you feel that the power of the tool becomes
weaker, stop using the tool and recharge its battery.
If you continue to use the tool and exhaust the electric
current, the battery may be damaged and its life will
become shorter.
(2) 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.
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.
○ If the battery charger does not work while the battery
is mounted correctly, it is probable that the battery or
charger is malfunctioning. Take it to your authorized
Service Center.
