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.

1. Work area safety
   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 flammable 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.

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 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 ear 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 fi nger 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 and clothing away from moving parts.
   Loose clothes, jewellery or long hair can be caught in moving parts.
   g) If devices are provided for the connection of dust extraction and collection facilities, ensure these are connected and properly used.
   Use of dust collection can reduce dust-related hazards.
   h) Do not let familiarity gained from frequent use of tools allow you to become complacent and ignore tool safety principles.
   A careless action can cause severe injury within a fraction of a second.

4. Power tool use and care
   a) Do not force the power tool. Use the correct power tool for your application.
   The correct power tool will do the job better and safer at the rate for which it was designed.
   b) Do not use the power tool if the switch does not turn it on and off .
   Any power tool that cannot be controlled with the switch is dangerous and must be repaired.
   c) Disconnect the plug from the power source and/or remove the battery pack, if detachable, from the power tool before making any adjustments, changing accessories,  or storing power tools.
   Such preventive safety measures reduce the risk of starting the power tool accidentally.
   d) Store idle power tools out of the reach of children and do not allow persons unfamiliar with the power tool or these instructions to operate the power tool.
   Power tools are dangerous in the hands of untrained users.
   e) Maintain power tools and accessories. Check for misalignment or binding of moving parts, breakage of parts and any other condition that may aff ect the power toolʼs  operation. If damaged, have the power tool repaired before use.
   Many accidents are caused by poorly maintained power tools.
   f) Keep cutting tools sharp and clean.
   Properly maintained cutting tools with sharp cutting edges are less likely to bind and are easier to control.
   g) Use the power tool, accessories and tool bits etc. in accordance with these instructions, taking into account the working conditions and the work to be performed.
   Use of the power tool for operations diff erent from those intended could result in a hazardous situation.
   h) Keep handles and grasping surfaces dry, clean and free from oil and grease.
   Slippery handles and grasping surfaces do not allow for safe handling and control of the tool in unexpected situations.

5. Service
   a) Have your power tool serviced by a qualified 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.

MASONRY DRILL SAFETY WARNINGS

Safety instructions for all operations
a) Wear ear protectors when impact drilling.
Exposure to noise can cause hearing loss.
b) Use the auxiliary handle(s).
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 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.

Safety instructions when using long drill bits
a) Never operate at higher speed than the maximum speed rating of the drill bit.
At higher speeds, the bit is likely to bend if allowed to rotate freely without contacting the workpiece, resulting in personal injury.
b) 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.
c) 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.

ADDITIONAL SAFETY WARNINGS

1. Make sure to securely hold the tool during operation.
   Failure to do so can result in accidents or injuries  (Fig. 11).

2. Before drilling into walls, ceilings or fl oors, ensure that there are no concealed power cables inside.

3. Always use side handle and hold the tool fi rmly with both hands.

4. Always use the masonry drill with clockwise rotation, when using it as a masonry drill. (Fig . 10)

○ By ROTATIONAL action: Boring holes in metal, wood and plastic.

PRIOR TO OPERATION

1. Power source
   Ensure that the power source to be utilized conforms to the power requirements specifi ed on the product nameplate.

2. Power switch
   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, inviting serious accident.

3. Extension cord
   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. Selecting the appropriate drill bit
   ○ When boring concrete or stone
   Use the drill bits specifi ed in the Optional Accessories.
   ○ When boring metal or plastic
   Use an ordinary metalworking drill bit.
   ○ When boring wood
   Use an ordinary woodworking drill bit.
   However, when drilling 6.5 mm or smaller holes, use a metalworking drill bit.

5.   Mounting and dismounting of the bit
   The country of use will determine whether Type A or Type B keyless chuck is required.
   ○ Type A (Fig. 1)
   (1) Mounting the bit
   Turn the lock collar in the direction “AUF” and open the chuck. After inserting the drill bit into the chuck as far it will go, turn the lock collar in the “ZU” direction.  Grip the ring and close the chuck by turning the sleeve clockwise as viewed from the front.
   (2) Dismounting the bit
   Turn the lock collar in the direction “AUF” to release the chucking force. Grip the ring and open the chuck by turning the sleeve counterclockwise.
   NOTE
   When the sleeve does not become loose any further, fix the side handle to ring, hold side handle fi rmly, then turn the sleeve to loosen by hand. (Fig. 3)
   ○ Type B (Fig. 2)
   (1) Mounting the bit
   Turn the sleeve counterclockwise and open the chuck.
   After inserting the drill bit into the chuck as far it will go, grip the ring and close the chuck by turning the sleeve clockwise as viewed from the front.
   (2) Dismounting the bit
   Grip the ring and open the chuck by turning the sleeve counterclockwise.
   NOTE
   When the sleeve does not become loose any further, fix the side handle to ring, hold side handle fi rmly, then turn the sleeve to loosen by hand. (Fig. 3)

6. Check the rotational direction (Fig. 4)
   The bit rotates clockwise (viewed from the rear side) by pushing the R-side of the push button.
   The L-side of the push button is pushed to turn the bit counterclockwise.
   (The L and R marks are provided on the body.)
   CAUTION
   Always use the masonry drill with clockwise rotation, when using it as a masonry drill.

7. Fixing the side handle (Fig. 5)
   Attach the side handle to the mounting part.
   Rotate the side handle grip in a clockwise direction to secure it.
   Set the side handle to a position that is suited to the operation and then securely tighten the side handle grip.
   To attach a depth gauge on the side handle, insert the gauge into the U-shaped groove on the side handle, adjust the position of the depth gauge in accordance with the  desired depth of the hole, and fi rmly tighten the side handle grip. (Fig. 6)

8. IMPACT to ROTATION changeover (Fig. 7)
   Shift the change lever between the right and left positions to switch easily between IMPACT (rotation and impact) and ROTATION (rotation only), respectively.
   To bore holes in hard materials such as concrete, stone and tiles, shift the change lever to the right-hand position (as indicated by the mark).
   The drill bit operates by the combined actions of impact and rotation.
   To bore holes in metal, wood and plastic, shift the change lever to the left- hand position (as indicated by the mark). The drill bit operates by rotational action only, as in the case of a conventional electric drill.
   CAUTION
   ○ Do not use the masonry Drill in the IMPACT function if the material can be bored by rotation only. Such action will not only reduce drill effi ciency, but may also  damage the drill tip.
   ○ Operating the masonry Drill with the change lever in mid-position may result in damage. When switching, make sure that you shift the change lever to the correct  position.

9. High-speed/Low-speed changeover:
   Prior to changing speed, ensure that the switch is in the OFF position, and the drill has come to a complete stop. To change speed, rotate the gear shift dial as indicated by the arrow in Fig. 8. The numeral “1” engraved on the drill body denotes low speed, the numeral “2” denotes high speed.
   If it is hard to turn the gear shift dial, turn the chuck slightly in either direction and then turn the gear shift dial again.

HOW TO USE

1. Switch operation
   ○ When the trigger is depressed, the tool rotates. When the trigger is released, the tool stops.
   ○ The rotational speed of the drill can be controlled by varying the amount that the trigger switch is pulled.
   Speed is low when the trigger switch is pulled slightly and increases as the trigger switch is pulled more.
   ○ The desired rotation speed can be pre-selected with the speed control dial.
   Turn the speed control dial clockwise for higher speed and counterclockwise for lower speed. (Fig. 9)
   ○ Pulling the trigger and pushing the stopper, it keeps the switched-on condition which is convenient for continuous running. When switching off , the stopper can be disconnected by pulling the trigger again.
   CAUTION
   If the L-side of push button is pressed for reverse bit rotation, the stopper cannot be used.

2. Drilling
   ○ When drilling, start the drill slowly, and gradually increasing speed as you drill.
   ○ Always apply pressure in a straight line with the bit. Use enough pressure to keep drilling, but do not push hard enough to stall the motor or defl ect the bit.
   ○ To minimize stalling or breaking through the material, reduce pressure on drill and ease the bit through the last part of the hole.
   ○ If the drill stalls, release the trigger immediately, remove the bit from the work and start again. Do not click the trigger on and off in an attempt to start a stalled drill.  This can damage the drill.
   ○ The larger the drill bit diameter, the larger the reactive force on your arm.
   Be careful not to lose control of the drill because of this reactive force.
   To maintain fi rm control, establish a good foothold, use side handle, hold the drill tightly with both hands, and ensure that the drill is vertical to the material being drilled.

MAINTENANCE AND INSPECTION

1. Inspecting the drill bits
   Since use of an abraded drill bits will cause motor malfunctioning and degraded effi ciency, replace the drill bits with a new one or resharpening without delay when abrasion is noted.

2. Inspecting the mounting screws
   Regularly inspect all mounting screws and ensure that they are properly tightened. Should any of the screws be loose, retighten them immediately. Failure to do so could
   result in serious hazard.

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.

4. Inspecting the carbon brushes
   For your continued safety and electrical shock protection, carbon brush inspection and replacement on this tool should ONLY be performed by a HiKOKI Authorized
   Service Center.
