English
2) Electrical safety a) Power tool plugs must match the outlet. Never modify the plug in any way. Do not use any adapter plugs with earthed (grounded) power tools. Unmodified plugs and matching outlets will reduce risk of electric shock. b) Avoid body contact with earthed or grounded surfaces, such as pipes, radiators, ranges and refrigerators. There is an increased risk of electric shock if your body is earthed or grounded. c) Do not expose power tools to rain or wet conditions. Water entering a power tool will increase the risk of electric shock. d) Do not abuse the cord. Never use the cord for carrying, pulling or unplugging the power tool. Keep cord away from heat, oil, sharp edges or moving parts. Damaged or entangled cords increase the risk of electric shock. e) When operating a power tool outdoors, use an extension cord suitable for outdoor use. Use of a cord suitable for outdoor use reduces the risk of electric shock. f) If operating a power tool in a damp location is unavoidable, use a residual current device (RCD) protected supply. Use of an RCD reduces the risk of electric shock.
3) Personal safety a) Stay alert, watch what you are doing and use common sense when operating a power tool. Do not use a power tool while you are tired or under the influence of drugs, alcohol or medication. A moment of inattention while operating power tools may result in serious personal injury. b) Use personal protective equipment. Always wear eye protection. Protective equipment such as a dust mask, non-skid safety shoes, hard hat or hearing protection used for appropriate conditions will reduce personal injuries. c) Prevent unintentional starting. Ensure the switch is in the off-position before connecting to power source and/or battery pack, picking up or carrying the tool. Carrying power tools with your finger on the switch or energising power tools that have the switch on invites accidents. d) Remove any adjusting key or wrench before turning the power tool on. A wrench or a key left attached to a rotating part of the power tool may result in personal injury. e) Do not overreach. Keep proper footing and balance at all times. This enables better control of the power tool in unexpected situations. f) Dress properly. Do not wear loose clothing or jewellery. Keep your hair, clothing and gloves away from moving parts.

English
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, first 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 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 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.

HOW TO USE

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. How to drill holes (Fig. 24) (1) Pull the switch trigger after applying the drill bit tip
to the drilling position. (2) It is unnecessary to forcibly press the Rotary
Hammer main body. It is sufficient to slightly press the rotary hammer to an extent that clips are freely discharged.

CAUTION

Fig. 24

Although this machine is equipped with a slip clutch, if the drill bit becomes bound

in concrete or other material, the resultant stoppage of the drill bit could cause the

machine body to turn in reaction. Ensure that the main handle and side handle are

gripped firmly during operation.

2. How to chisel or demolish (Fig. 25) By applying the tool tip to the chiseling or demolishing position, operate the rotary hammer by utilizing its own weight. Forcible pressing or thrusting is unnecessary.

3. Install the stopper (Fig. 26) (1) Loosen the wing bolt, and insert the stopper
into the mounting hole on the side handle. (2) Adjust the stopper position according to the
depth of the hole and tighten the wing bolt securely.

HOW TO USE THE CORE BIT
When boring penetrating large hole use the core bit. At that time use with the center pin and the core bit shank provided as optional accessories.
1. Mounting
WARNING
To prevent accidents, make sure to turn the switch off and disconnect the battery.
(1) Mount the core bit to the core bit shank. (Fig. 28) Lubricate the thread of the core bit shank to facilitate disassembly.
(2) Mount the core bit shank to the Rotary Hammer. (Fig. 29) (3) Insert the center pin into the guide plate until it stops. (4) Engage the guide plate with the core bit, and turn the guide plate to left or right so that it
does not fall even if it faces downward. (Fig. 30)

2. How to bore (Fig. 31)

(1) Install the battery.

(2) A spring is installed in the center pin. Push it lightly

to the wall or the floor straight. Connect all over the

surface of the core bit tip and start operating.

(3) When boring about 5 mm in depth the position of the

hole will establish. Bore after that removing the center

pin and the guide plate from core bit. (4) Application of excessive force will not only expedite the

Fig. 31

work, but will deteriorate the tip edge of the drill bit, resulting in reduced service life of the

rotary hammer.

WARNING
When removing the center pin and the guide plate, turn OFF the switch and disconnect the battery.

3. Dismounting (Fig. 32)

Remove the core bit shank from the rotary hammer and

strike the head of the core bit shank strongly two or three

times with a manual hammer holding the core bit, then the thread becomes loose and the core bit can be removed.

REACTIVE FORCE CONTROL

This product is equipped with a Reactive Force Control

Arms are twisted

(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. 33)

Fig. 33

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 and hold

power tool firmly while operating.

60

English
Possible causes of sudden overburdening Tool bit biting into material Impact against nails, metal or other hard objects 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.
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.

MAINTENANCE AND INSPECTION

WARNING
Be sure to turned off the switch and remove the battery before maintenance and inspection.
1. Inspecting the tool bits Since use of a dull tool will cause motor malfunctioning and degraded efficiency, replace the tool bit with a new one or resharpening without delay when abrasion is noted.
2. Inspecting the screws Regularly inspect all mounting screws and ensure that they are properly tightened. Should any of the screws be loose, retighten them immediately.
WARNING
Using this Rotary Hammer with loosen screws is extremely dangerous.
3. Maintenance of the motor The motor unit winding is the very “heart” of the power tool. Exercise due care to ensure the winding does not become damaged and/or wet with oil or water.
