NOTE

Be sure to pull out the battery from the battery 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 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.

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 rest until the next charging.
• 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 UC18YSL3 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 flickers (at 0.2-second intervals), check for and take out any foreign objects in the charger's battery installation hole. If there are no foreign objects, it is probable that the battery or charger is malfunctioning. Take it to your authorized Service Center.

HOW TO USE

WARNING

To prevent accidents, make switch off and disconnect the battery when the drill bits and other various parts are installed or removed. The power switch should also be turned off during a work break and after work.

CAUTION

To extend the lifetime, the lithium-ion battery equips with the protection function to stop the output. Therefore, if the tool is overloaded, the motor may stop. However, this is not the trouble but the result of protection function. In this case, release the switch of tool and eliminate the causes of overloading.

1. Switch operation
   When the switch trigger is depressed, the tool rotates. When the switch trigger is released, the tool stops.
   The rotational speed of the rotary hammer can be controlled by varying the amount that the switch trigger is pulled. Speed is low when the switch trigger is pulled slightly and increases as the switch trigger is pulled more.
   When releasing the switch trigger, the brake will be applied for immediate stopping.

2. Rotation + hammering

This rotary hammer can be set to rotation and hammering mode by pressing the push button and turning the change lever to the ⚪ mark (Fig. 18).

Fig. 22

CAUTION

● Exercise care not to excessively prolong driving time, otherwise, the screws may be damaged by excessive force.
- Apply the rotary hammer perpendicularly to the screw head when driving the screw; otherwise, the screw head or bit will be damaged, or driving force will not be fully transferred to the screw.
- Do not attempt to use the rotary hammer in the rotation and striking function with the chuck adapter and bit attached.

5. When driving wood screws (Fig. 22)

(1) Selecting a suitable driver bit
Employ plus-head screws, if possible, since the driver bit easily slips off the heads of minus-head screws.
(2) Driving in wood screws.
Prior to driving in wood screws, make pilot holes suitable for them in the wooden board. Apply the bit to the screw head grooves and gently drive the screws into the holes.
○ After rotating the rotary hammer at low speed for a while until the wood screw is partly driven into the wood, squeeze the trigger more strongly to obtain the optimum driving force.

CAUTION

Exercise care in preparing a pilot hole suitable for the wood screw taking the hardness of the wood into consideration. Should the hole be excessively small or shallow, requiring much power to drive the screw into it, the thread of the wood screw may sometimes be damaged.

6. Hammering only

OPERATIONAL CAUTIONS

Resting the unit after continuous work

(1) The power tool is equipped with a temperature protection circuit to protect the motor.
Continuous work may cause the temperature of the unit to rise, activating the temperature protection circuit and automatically stopping operation.
If this happens, allow the power tool to cool before resuming use.
(2) After use for continuous works, rest the unit for 15 minutes or so when replacing the battery. The temperature of the motor, switch, etc., will rise if the work is started again immediately after battery replacement, eventually resulting in burnout.

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

○ Rotation speed (Low mode/Normal mode) (Fig. 29) Select either Low mode or Normal mode and operate the tool in the selected speed.

Changeover switch Display lamp

Lighting status of display lamp
Number of rotations (/min) 700 950
Number of impacts (/min) 3,170 4,300

Fig. 29

○ Auto stop mode (on/off) (Fig. 30)

This product is equipped with an auto stop fu 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. 30)

Changeover switch Auto stop lamp: Blinks Auto stop lamp: Lights

Fig. 30

(At the same time the auto stop lamp will blink.)

Conduct drilling when the auto stop lamp is flashing. The time between switching ON and switching OFF is stored by the tool.

Conduct drilling when the auto stop lamp is flashing. Continuous drilling is possible as the memory storage time will be recorded by the tool until the auto stop function 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 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 RFC indicator lamp (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. 31)

Because the RFC feature may not activate or its performance may be insufficient 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.
