GENERAL POWER TOOL SAFETY WARNINGS

WARNING

Read all safety warnings, instructions, illustrations and specific cations provided with this power tool.

Failure to follow all instructions listed below may result in electric shock, fire 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. 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 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 affect the power tool's 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 infirm persons away.

When not in use, tools should be stored out of reach of children and infirm persons.

ROTARY HAMMER SAFETY WARNINGS

Safety instructions for all operations

1. Wear ear protectors

Exposure to noise can cause hearing loss.

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

Loss of control can cause personal injury.

1. 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 with rotary hammers

1. 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.

1. 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.

PRIOR TO OPERATION

1. Power source

Ensure that the power source to be utilized conforms to the power requirements specified on the product nameplate.

2. Power switch

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

3. Extension cord

When the work area is removed from the power source, use an extension cord of sufficient thickness and rated capacity. The extension cord should be kept as short as practicable.

4. Mounting the drill bit (Fig. 1)

CAUTION

To prevent accidents, make sure to turn the switch off and disconnect the plug from the receptacle.

NOTE

When using tools such as bull points, drill bits, etc., make sure to use the genuine parts designated by our company.

(1) Clean the shank portion of the drill bit.
(2) Insert the drill bit in a twisting manner into the tool holder until it latches itself. (Fig. 1)
(3) Check the latching by pulling on the drill bit.
(4) To remove the drill bit, fully pull the grip in the direction of the arrow and pull out the drill bit. (Fig. 2)
5. Installation of dust cup or dust collector (B) (Optional accessories) (Fig. 3, Fig. 4)

When using a rotary hammer for upward drilling operations attach a dust cup or dust collector (B) to collect dust or particles for easy operation.

Installing the dust cup

Use the dust cup by attaching to the drill bit as shown in Fig. 3.

When using a bit which has big diameter, enlarge the center hole of the dust cup with this rotary hammer.

Installing dust collector (B)

When using dust collector (B), insert dust collector (B) from the tip of the bit by aligning it to the groove on the grip. (Fig. 4)

CAUTION

The dust cup and dust collector (B) are for exclusive use of concrete drilling work. Do not use them for wood or metal drilling work.

• Insert dust collector (B) completely into the chuck part of the main unit.

• When turning the rotary hammer on while dust collector (B) is detached from a concrete surface, dust collector (B) will rotate together with the drill bit. Make sure to turn on the switch after pressing the dust cup on the concrete surface. (When using dust collector (B) attached to a drill bit that has more than 190mm of overall length, dust collector (B) cannot touch the concrete surface and will rotate. Therefore please use dust collector (B) by attaching to drill bits which have 166mm , 160mm , and 110mm overall length.)

Dump particles after every two or three holes when drilling.

Please replace the drill bit after removing dust collector (B).

6. Selecting the driver bit

Screw heads or bits will be damaged unless a bit appropriate for the screw diameter is employed to drive in the screws.

7. Confirm the direction of bit rotation (Fig. 5)

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.

8. Selecting the function mode

You can switch functions to the 3 modes of "hammering only, "rotation ^+ hammering", and "rotation only" by turning the change lever while pressing the push button. Set the mark position of the change lever to that of the mode to be used.

CAUTION

Before operating the change lever, check and make sure that the motor has stopped.
A failure can occur if it is operated while the motor is running.
To operate the change lever, press the push button, and release the lock of the change lever. Also, check and make sure after operation that the push button has returned and that the change lever has been locked.
- Switch the change lever without mistake. If it is used at a position halfway, there is a fear that the service life of the switching mechanism may be shortened.

HOW TO USE

CAUTION

To prevent accidents, make sure to turn the switch off and disconnect the plug from the receptacle when the drill pits and other various parts are installed or removed. The power switch should also be turned off during a work break and after work.

NOTE

Ensure that the wing bolt in the side handle is properly tightened before using the tool.

1. Switch operation

The rotation speed of the drill bit can be controlled steplessly by varying the amount that the trigger switch is pulled. Speed is low when the trigger switch is pulled slightly and increases as the switch is pulled more.

However, the switch trigger can only be pulled in halfway during reverse and rotates at half the speed of forward operation.

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 T mark. (Fig. 6)

Turn the grip slightly and confirm that the clutch has been engaged with a click.

(1) Mount the drill bit.
(2) Pull the trigger switch after applying the drill bit tip to the drilling position. (Fig. 7)
(3) Pushing the rotary hammer forcibly is not necessary at all. Pushing slightly so that drill dust comes out gradually is sufficient.

CAUTION

When the drill bit touches construction iron bar, the bit will stop immediately and the rotary hammer will react to revolve. Therefore grip the side handle and handle tightly as shown in Fig. 7.

3. Using the dust-collecting unit

Using the rotary hammer with the dust-collecting unit attached creates a more hygienic working environment free of flying dust (Fig. 8).

(1) Attaching the dust-collecting unit

Insert the dust-collecting unit along the rail on the rotary hammer. When it is inserted as far as it will go, fix it to the rotary hammer with the two latches (Fig. 9).

CAUTION

The dust-collecting unit is designed for use when drilling concrete. Do not use for drilling holes in metal or wood.

(2) Adjusting the dust-collecting unit

(a) Adjusting the position of the dust-collecting nozzle
Push the nozzle in and adjust to the desired position.
Pull the adjuster on the nozzle in the direction of the arrow to release the lock and move until it contacts with the adjuster rod. Push the adjuster in the opposite direction to the arrow to lock (Fig. 10).
(b) Setting the hole-drilling depth

Pull the adjuster on the handle in the direction of the arrow to release the lock, move to the desired position to determine the stroke, and push the adjuster in the opposite direction to the arrow to lock.

The nozzle travel distance when the tip of the nozzle matches the tip of the drill bit is the hole-drilling depth. (Fig. 11)

The maximum hole-drilling depth when using the dust-collecting unit is 85mm
When using the dust-collecting unit, it is possible to use HiKOKI drill bits between 4mm and 18mm in diameter and up to 100mm in effective length.

(3) Drilling holes

When drilling holes, hold the rotary hammer so that the tip of the nozzle contacts with the concrete surface. Dust-collecting effectiveness is reduced if the unit is not in contact with the surface (Fig. 12).

(4) Removing dust

Excessive dust in the dust box will reduce dust-collecting effectiveness. Empty the dust box regularly.

Push the lever to remove the dust box from the dust-collecting unit, and empty and clean the box (Fig. 13).

Dust-collecting effectiveness is reduced if the filter in the dust box becomes blocked.

Use the table below as a guide to replacement of the dust box.

Dust box capacity Drill diameter of 6 mm / depth of 28 mm: 130 holes Drill diameter of 8 mm / depth of 30 mm: 75 holes Drill diameter of 12 mm / depth of 50 mm: 20 holes
Guide to replacement of dust box	Dust box has been filled and emptied 100 times

(5) Replacing the rubber cap

Wear of the rubber cap will reduce dust-collecting effectiveness.

Replace the rubber cap when it becomes worn.

How to replace the rubber cap (Fig. 14)

(1) Remove the nozzle seal from the nozzle.

(2) Replace the rubber cap with a new cap.

Fit the rubber cap making sure that it is correctly oriented.

(3) Attach the nozzle seal.

Insert the lip of the nozzle seal securely into the groove of the nozzle.

At this time, make sure that the groove between the nozzle and the nozzle seal is uniform all the way round.

4. When not using the dust-collecting unit

When using the rotary hammer without the dust-collecting unit, attach the provided cover in the unit attachment hole (Fig. 15).

CAUTION

If no cover is attached, dust or other particles may be sucked up from the hole, causing damage to the motor.

5. Rotation only

NOTE

The dust-collecting unit cannot be used. Remove the unit and attach the provided cover in the unit attachment hole.

CAUTION

If no cover is attached, dust or other particles may be sucked up from the hole, causing damage to the motor.

This rotary hammer can be set to rotation only mode by pressing the push button and turning the change lever to the mark. (Fig. 16)

Turn the grip slightly and confirm that the clutch has been engaged with a click.

To drill wood or metal material using the drill chuck and chuck adapter (optional accessories), proceed as follows.

Installing drill chuck and chuck adapter: (Fig. 17)

(1) Attach the drill chuck to the chuck adapter.
(2) The part of the SDS-plus shank is the same as the drill bit. Therefore, refer to the item of "Mounting the drill bit" for attaching it.

CAUTION

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.

6. When driving machine screws (Fig. 18)

First, insert the bit into the socket in the end of chuck adapter (D).

Next, mount chuck adapter (D) on the main unit using procedures described in 4 (1), (2), (3), put the tip of the bit in the slots in the head of the screw, grasp the main unit and tighten the screw.

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 hammering function with the chuck adapter and bit attached.

7. When driving wood screws (Fig. 18)

(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.

8. Hammering only

NOTE

The dust-collecting unit cannot be used. Remove the unit and attach the provided cover in the unit attachment hole.

CAUTION

If no cover is attached, dust or other particles may be sucked up from the hole, causing damage to the motor.

This rotary hammer can be set to hammering only mode by pressing the push button and turning the change lever to the T mark (Fig. 19).

(1) Mount the bull point or cold chisel.
(2) Press the push button and set the change lever to mark. (Fig. 20)

The rotation is released, turn the tool and adjust the tool to desired position. (Fig. 21)

(3) Turn the change lever to T mark. (Fig. 19)
Then bull point or cold chisel is locked.

9. Using the stopper (Fig. 22)

(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.

1. How to use the drill bit (taper shank) and the taper shank adapter

(1) Mount the taper shank adapter to the rotary hammer. (Fig. 23)
(2) Mount the drill bit (taper shank) to the taper shank adapter. (Fig. 23)
(3) Turn the switch ON, and drill a hole in prescribed depth.
(4) To remove the drill bit (taper shank), insert the cotter into the slot of the taper shank adapter and strike the head of the cotter with a hammer supporting on a rests. (Fig. 24)

1. Make sure to securely hold the tool as shown in Fig. 31 during operation.

12. Using the side handle

When you wish to change a position of the side handle, turn grip of the side handle counterclockwise to loosen it, and then fasten it firmly. (Fig. 32)

CAUTION

When boring a hole, there can be a case where the machine attempts to rotate by the reaction at the time of penetrating a concrete wall and/or when a tip of the blade comes in contact with the rebar.

Firmly fasten the side handle and hold the machine with both of your hands. Unless you hold it securely, an accident can occur.

HOW TO USE THE CORE BIT (FOR LIGHT LOAD)

When boring penetrating large holes use the core bit (for light loads). At that time use with the center pin and the core bit shank provided as optional accessories.

1. Mounting

CAUTION

Be sure to turn power OFF and disconnect the plug from the receptacle.

(1) Mount the core bit to the core bit shank (Fig. 25). Lubricate the thread of the core bit shank to facilitate disassembly.
(2) Mount the core bit to the rotary hammer (Fig. 26).
(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 the left or the right so that it does not fall even if it faces downward (Fig. 27).

2. How to bore (Fig. 28)

(1) Connect the plug to the power source.
(2) A spring is installed in the center pin.

Push it lightly to the wall or the floor straight.

Connect the core bit tip flush to the surface and start operating.

(3) When boring about 5mm in depth the position of the hole will be established. Bore after that removing the center pin and the guide plate from core bit.

(4) Application of excessive force will not only expedite the work, but will deteriorate the tip edge of the drill bit, resulting in reduced service life of the rotary hammer.

CAUTION

When removing the center pin and the guide plate, turn OFF the switch and disconnect the plug from the receptacle.

3. Dismounting (Fig. 29)

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 hammer holding the core bit, then the thread becomes loose and the core bit can be removed.

GREASE REPLACEMENT

This Rotary Hammer is of full air-tight construction to protect against dust. This machine can be used without grease replenishment for an extended period of time. However, perform the grease replacement to extend the service life. Replace the grease as described below.

1. Grease Replacement Period

You should look at the grease when you change the carbon brush. (See item 4 in the section MAINTENANCE AND INSPECTION.)

Ask for grease replacement at the nearest authorized HiKOKI Service Center.
