GENERAL POWER TOOL SAFETY

WARNINGS WARNING Read all safety warnings, instructions, illustrations and specifi cations provided with this power tool. Failure to follow all instructions listed below may result in electric shock, fi re and/or serious injury. Save all warnings and instructions for future reference. The term “power tool” in the warnings refers to your mains- operated (corded) power tool or battery-operated (cordless) power tool.

a) Keep work area clean and well lit. Cluttered or dark areas invite accidents. b) Do not operate power tools in explosive atmospheres, such as in the presence of fl ammable liquids, gases or dust. Power tools create sparks which may ignite the dust or fumes. c) Keep children and bystanders away while operating a power tool. Distractions can cause you to lose control.

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. Unmodifi ed 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.

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 infl uence 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.

ADDITIONAL SAFETY WARNINGS

1. Ensure that the power source to be utilized conforms

to the power requirements specifi ed on the product nameplate.

2. Ensure that the power switch is in the OFF position.

If the plug is connected to a receptacle while the power switch is in the ON position, the power tool will start operating immediately, which could cause a serious accident.

3. When the work area is removed from the power source,

use an extension cord of suffi cient thickness and rated capacity. The extension cord should be kept as short as practicable.

4. Do not touch the bit during or immediately after

operation. The bit becomes very hot during operation and could cause serious burns.

5. Before starting to break, chip or drill into a wall, fl oor or

ceiling, thoroughly confi rm that such items as electric cables or conduits are not buried inside.

6. Always hold the body handle and side handle of the

power tool fi rmly. Otherwise the counterforce produced may result in inaccurate and even dangerous operation.

Do not inhale the harmful dusts generated in drilling or chiseling operation. The dust can endanger the health of yourself and bystanders.

8. Mounting the tool

○ To prevent accidents, make sure to turn the switch off and disconnect the plug from the receptacle. ○ When using tools such as bull points, drill bits, etc., make sure to use the genuine parts designated by our company. ○ Clean the shank portion of the tool. ○ Check the latching by pulling on the tool.

9. To prevent accidents, make sure to turn the switch off

and disconnect the plug from the receptacle 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.

10. Rotation + hammering

When the drill bit touches construction iron bar, the bit will stop immediately and the rotary hammer will react to revolve. Therefore fi rmly tighten the side handle.

To drill wood or metal material using the drill chuck and chuck adapter (optional accessories). ○ Application of force more than necessary will not only expedite the work, but will deteriorate the tip edge of the drill bit and reduce the service life of the rotary hammer in addition. ○ Drill bits may snap off while withdrawing the rotary hammer from the drilled hole. For withdrawing, it is important to use a pushing motion. ○ Do not attempt to drill anchor holes or holes in concrete with the machine set in the rotation only function. ○ Do not attempt to use the rotary hammer in the rotation and hammering function with the drill chuck and chuck adapter attached. This would seriously shorten the service life of every component of the machine. 12 RCD The use of a residual current device with a rated residual current of 30 mA or less at all times is recommended.

13. Make sure to securely hold the tool as shown in Fig. 12

a) Have your power tool serviced by a qualifi ed repair person using only identical replacement parts. This will ensure that the safety of the power tool is maintained. PRECAUTION Keep children and infi rm persons away. When not in use, tools should be stored out of reach of children and infi rm persons.

1) Safety instructions for all operations

a) Wear ear protectors Exposure to noise can cause hearing loss. b) Use auxiliary handle(s), if supplied with the tool. Loss of control can cause personal injury. c) Hold the power tool by insulated gripping surfaces, when performing an operation where the cutting accessory may contact hidden wiring. Cutting accessory contacting a “live” wire may make exposed metal parts of the power tool “live” and could give the operator an electric shock.

2) Safety instructions when using long drill bits with

rotary hammers a) Always start drilling at low speed and with the bit tip in contact with the workpiece. At higher speeds, the bit is likely to bend if allowed to rotate freely without contacting the workpiece, resulting in personal injury. b) Apply pressure only in direct line with the bit and do not apply excessive pressure. Bits can bend causing breakage or loss of control, resulting in personal injury. 0000BookDH28PEC.indb30000BookDH28PEC.indb3 2022/12/0714:01:112022/12/0714:01:114 English SYMBOLS WARNING The following show symbols used for the machine.

Pressing the changeover switch allows the selection of rotation speed and the auto stop function. ○ Rotation speed (Low mode/Normal mode) Select either Low mode or Normal mode and operate the tool in the selected speed. ○ Auto stop mode (on/off ) 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.

In selection mode, pressing the button for longer than two seconds will move to memory mode. (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.

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. When the RFC is activated, the two LEDs fl ash red in a synchronized manner. (Table 1) During the fl ashing, the motor will be off . Press the changeover switch to recommence operation. 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 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.
