Before Use - Hitachi NR 90GC Instrucciones De Manejo

About 60 minutes is required to fully charge the
battery at a temperature of about 20°C. The pilot lamp
goes off to indicate that the battery is fully charged.
The battery charging time becomes longer when a
temperature is low or the voltage of the power source
is too low.
When the pilot lamp does not go off even if more than
120 minutes have elapsed after starting of the
charging, stop the charging and contact your HITACHI
AUTHORIZED SERVICE CENTER.
CAUTION
If the battery is heated due to direct sunlight, etc.,
just after operation, the charger pilot lamp may
not light up. At that time, cool the battery first,
then start charging.
3. Disconnect the charger power cord from the
receptacle
4. Hold the charger firmly and pull out the battery
NOTE
After charging, pull out batteries from the charger first,
and then keep the batteries properly.
Regarding electric discharge in case of new
batteries, etc.
As the internal chemical substance of new batteries and
batteries that have not been used for an extended period
is not activated, the electric discharge might be low when
using them the first and second time. This is a temporary
phenomenon, and normal time required for recharging
will be restored by recharging the batteries 2 – 3 times.
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.
PREPARATION PRIOR TO OPERATION
CAUTIONS
No flammable gas, liquid or other flammable objects
at worksite.
Use outside or well–ventilated areas.
Do not inhale.
Keep the tool, fuel cell and battery away from sunshine
and from temperature exceeding 50°C (120°F).
Keep away from ignition sources. No smoking.
Clear the area of children or unauthorized personnel.
Do not store the tool, fuel cell and battery in a cold
weather environment. Keep the tool, fuel cell and
battery in a warm area until beginning the work.
If the tool, fuel cell and battery are already cold, bring
it in a warm area and allow the tool to warm up before
use.
Observe temperature limit of max. 50°C (120°F).
Do not expose to an open flame and sparks!
This tool may not drive completely below when;
– at low temperature fuel cell loose the required
propellant force,
– at high temperature fuel cell overdose.
Do not use the tool in the rain or where excessive
moisture is present.
This tool is not recommended for use at altitudes
above 1,500 m (5000 feet), or in temperature below
0°C (30°F).
1. Fuel cell
To attach the metering valve to a fuel cell:
(1) Separate the metering valve and the cap from the gas
cartridge (See Fig. 3 (1)).
(2) Press forward (stem side) and downward on the front
side of the metering valve (See Fig. 3 (2)).
(3) Press downward on the rear of the metering valve
until it seals (See Fig. 3 (3)).
Check the metering valve:
Press the metering valve stem on fuel cell two or three
times against a stationary object and release.
If gas is not dispersed, fuel cell is empty. Replace it.
Observe Safety Regulations
CAUTION
If the gas leaks from the metering valve or the gas
cartridge after attached the metering valve, replace
with the new metering valve.
Do not attempt to reuse the metering valve.
Replace with the new metering valve.
2. Battery
You must charge the battery before use.
The charging method of battery is shown in page 9.
3. Check on safety
CAUTIONS
Unauthorized persons (including children) must be
kept away from the equipment.
Wear eye protector.
Check the retaining screws which fix the top cover,
etc. for tightness.
Check the tool for defective or rusty parts.
Check whether or not the push lever works correctly
without nails, fuel cell and battery. Also check whether
or not any dirt has adhered to the moving parts of the
push lever.
Recheck on operational safety.

BEFORE USE

1. Insert battery into the tool (See Fig. 4)
Do not operate the push lever or trigger while
installing the battery.
Make sure the battery indicator light is flashing GREEN
(See Fig. 5).
If the battery indicator light is flashing RED, the battery
doesn't have enough power and it needs to be
charged.
BATTERY INDICATOR LIGHT
– Flashing GREEN: Enough power remaining (The
– Flashing RED: Insufficient power remaining (The
light turns steady during operation).
– OFF: Power saving mode is on. To deactivate it,
remove the battery once and reinstall the
battery.
