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.

GENERAL POWER TOOL SAFETY

WARNINGS WARNING Read all safety warnings and all instructions. Failure to follow the warnings and instructions 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. Protective equipment such as 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 (Original instructions) 0000BookDH24PG.indb20000BookDH24PG.indb2 2018/08/1014:59:062018/08/1014:59:063 English

Exposure to noise can cause hearing loss.

2. Use auxiliary handle(s), if supplied with the tool.

Loss of control can cause personal injury.

3. Hold power tool by insulated gripping surfaces,

when performing an operation where the cutting accessory may contact hidden wiring or its own cord. Cutting accessory contacting a “live” wire may make exposed metal parts of the power tool “live” and could give the operator an electric shock.

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 drill bit

○ 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 drill bit. ○ Check the latching by pulling on the drill bit.

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

DH28PMY only: Using drill bit holder (standard accessories) 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). DH28PMY only: Using drill chuck holder (standard 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 striking function with the drill chuck and chuck adapter attached. This would seriously shorten the service life of every component of the machine.
