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.

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.

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 charge indicator lamp of the charger lights for 0.3 seconds, does not light for 0.3 seconds (off for 0.3 seconds). In such a case, fi rst let the battery cool, then start charging.
• When the charge indicator lamp fl ickers (at 0.2-second 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 UC18YSL3 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.

MOUNTING AND OPERATION

Pressing the changeover switch allows the selection of rotation speed and the auto stop function.

• Rotation speed (Low mode/Normal mode) (Fig. 17) Select either Low mode or Normal mode and operate the tool in the selected speed.
• Auto stop mode (on/off ) (Fig. 18) This product is equipped with an auto stop function to support continuous drilling work. The function features a memory mode for storing the work time for drilling from switch ON to switch OFF, and an auto stop mode that automatically stops the motor from the second drilling onward should the work exceed the stored work time while the switch is ON.

AUTO STOP FUNCTION

• In selection mode, pressing the button for longer than two seconds will move to memory mode. (Fig. 18) (At the same time the auto stop lamp will blink.)

• Conduct drilling when the auto stop lamp is fl ashing. The time between switching ON and switching OFF is stored by the tool. (At the same time, the auto stop lamp will light up.)

• Conduct drilling when the auto stop lamp is fl ashing.

• Continuous drilling is possible as the memory storage time will be recorded by the tool until the auto stop function’s auto stop mode is cancelled.

• The auto stop function is cancelled by pressing the changeover switch once again for over two seconds. (At the same time, the auto stop lamp will switch off .)
  CAUTION

  • Switch ON the tool once you place the tip of the tool on the work material.
  • The rotation speed and the level at which the switch is pulled during drilling is not stored to memory.
  • Fully carry out drilling in one go during auto stop mode.
  • The motor will stop even if you switch OFF within the memory storage time.
  • When you switch OFF within the memory storage time, the count will be reset. If you rework a task in which a hole has been partially drilled, the memory storage time will be fully recounted.
  • The auto stop function will remain active until canceled.

REACTIVE FORCE CONTROL

• This product is equipped with a Reactive Force Control (RFC) feature that reduces jerking of the tool body.
• If the tool bit is suddenly overburdened, any jerking of the tool body is reduced by activation of the slip clutch or by stopping of the motor by the sensor built into the tool body.
• If the motor is stopped because of overburdening detection by the controller, the display lamp will blink while the switch is pulled. In addition, the lamp will continue blinking for approximately three seconds after the switch is released.
• The motor will remain stopped while the lamp is blinking. (Fig. 26)
• Because the RFC feature may not activate or its performance may be insuffi cient depending on the working environment and conditions, be careful not to suddenly overburden the tool bit while operating.
  • Possible causes of sudden overburdening
  1. Tool bit biting into material
  2. Impact against nails, metal or other hard objects
  3. Tasks involving prying or any excess application of pressure, etc. Also, other causes include any combination of the aforementioned.
  • When the reactive force control (RFC) is triggered
    When the RFC is triggered and the motor stops, turn off the tool’s switch and remove the cause of the overburdening before continuing operation.

LED LEVEL FUNCTION

   • Also, after cleaning, ensure that the battery can be installed and removed smoothly from the tool.
     CAUTION

   • Using the tool when the battery is covered with concrete dust may lead to accidents such as the battery falling during use.

   • Furthermore, such use may cause a malfunction or contact failure between the battery and the terminals.

7. Storage
   Store the power tool and battery in a place in which the temperature is less than 40°C and out of reach of children.

   • NOTE
   • Storing lithium-ion batteries.
   • Make sure the lithium-ion batteries have been fully charged before storing them.
   • Prolonged storage (3 months or more) of batteries with a low charge may result in performance deterioration, signifi cantly reducing battery usage time or rendering the batteries incapable of holding a charge.
   • However, signifi cantly reduced battery usage time may be recovered by repeatedly charging and using the batteries two to fi ve times.
   • If the battery usage time is extremely short despite repeated charging and use, consider the batteries dead and purchase new batteries.
   • CAUTION
     In the operation and maintenance of power tools, the safety regulations and standards prescribed in each country must be observed.
