CHARGING

Before using the power tool, charge the battery as follows.

1.  Insert the battery into the charger

  Insert the battery 

fi

 rmly while observing its direction, 

until it contacts the bottom of the charger (See 

Fig. 2

).

 CAUTION

  The UC7SD model is the exclusively designed 

charger. These cannot charge batteries except 

the speci

fi

 ed  batteries.  It  is  possible  to  insert  the 

batteries other than the speci

fi

 ed into the charger 

and some of them may light up the pilot lamps. 

However, you are requested to exercise utmost 

caution not to charge batteries other than speci

fi

 ed 

ones because these can not only be charged but 

also such actions can result in the malfunction of 

chargers.

2.  Connect the charger power cord to the receptacle

Connecting the power cord 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.

About 60 minutes is required to fully charge the battery 

at a temperature of about 20°C. The pilot lamp goes o

ff

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 o

ff

   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 

fi

 rst, then start 

charging.

3. Disconnect the charger power cord from the 

receptacle

4.  Hold the charger 

fi

 rmly and pull out the battery

NOTE

After charging, pull out batteries from the charger 

fi

 rst, 

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 

fi

 rst 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 

fl

 ammable gas, liquid or other 

fl

 ammable 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 

fl

 ame 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.
