NOTE

The charging time may vary according to temperature and power source voltage.

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.

5.Hold the charger firmly and pull out the battery.

NOTE

After operation, pull out batteries from the charger first, and then keep the batteries properly.

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

￿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 for 1 second, does not light for 0.5 seconds (off for 0.5 seconds). In such a case, first let the battery cool, then start charging.

￿When the pilot lamp flickers 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 confirm that the battery being charged with UC18YFSL 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.

￿If the pilot lamp does not blink in red (every second) even though the charger cord is connected to the power, it indicates that the protection circuit of the charger may be activated.

Remove the cord 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.

PRIOR TO OPERATION

1.Setting up and checking the work environment Check if the work environment is suitable by following the precautions.

2.Prepare a wooden workbench (Fig. 12)

Since the saw blade will extend beyond the lower surface of the lumber, place the lumber on a workbench when cutting. If a square block is utilized as a workbench, select level ground to ensure it is properly stabilized. An unstable workbench will result in hazardous operation.

CAUTION

To avoid possible accident, always ensure that the portion of lumber remaining after cutting is securely anchored or held in position.

ADJUSTING THE SAW PRIOR TO USE

CAUTION

Pull out battery before doing any adjusting.

1.Adjusting the cutting depth

As shown in Fig. 13, hold the handle with one hand while loosening the lever with the other.

The cutting depth can be adjusted by moving the base to the desired position. In such manner adjust the cutting depth and then securely retighten the lever.

2.Adjusting the angle of inclination

As shown in Fig. 14 by loosening the clamp lever on the incline gauge, the saw blade may be inclined to a maximum angle of 45° in relation to the base. After having completed the adjustment, reconfirm that the clamp lever are firmly tightened.
