WARNING! Read all instructions Failure to follow all instructions listed below may result in electric shock, fire and/or serious injury. The term “power tool” in all of the warnings listed below refers to your mains operated (corded) power tool or battery operated (cordless) power tool.

SAVE THESE INSTRUCTIONS

a) Keep work area clean and well lit. Cluttered and 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 of 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

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 safety equipment. Always wear eye protection. Safety equipment such as dust mask, non-skid safety shoes, hard hat, or hearing protection used for appropriate conditions will reduce personal injuries. c) Avoid accidental starting. Ensure the switch is in the off position before plugging in. Carrying power tools with your finger on the switch or plugging in 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. 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 these devices can reduce dust related hazards.

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 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. Check for misalignment or binding of moving parts, breakage of parts and any other condition that may affect the power tools 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 and in the manner intended for the particular type of power tool, taking into account the working conditions and the work to be performed. Use of the power tool for operations different from intended could result in a hazardous situation.

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. 01Eng_DH45SA_WE_6L 6/28/07, 12:225English

Exposure to noise can cause hearing loss.

2. Do not touch the bit during or immediately after

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

3. Before starting to break, chip or drill into a wall, floor

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

4. Use auxiliary handles supplied with the tool.

Loss of control can cause personal injury.

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

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

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

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. (1) Bull point Overall length: 280, 450 mm (1) Cold chisel Overall length: 280, 450 mm (1) Cutter

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. How to install tool

NOTE For tools such as a bull point and a cold chisel, use only Hitachi genuine parts. (1) Clean, then smear the tool shank with the grease provided in the green tube (Fig. 1). (2) Turn the grip fully in the direction of the arrow mark A, and put the mark 䢇 of the front washer and the mark of the grip together. (Fig. 2) (3) Insert the shank part of the tool into the hole deeply until it hits the end. (Fig. 2) (4) Bring the grip back to its home position. The tool will be fixed if you put the mark 䢇 of the front washer and the mark of the grip together. Pull the tool and check if the tool is surely fixed. For removal, perform the operation mentioned in (2) above, and pull the tool out.

When a worker is engaged in an operation with the main body faced upward, if a dust cup is fixed to a drill bit, the inside of a tool holder can be prevented from any possible invasion of dust. The dust cup should be fixed as explained below. (1) Insert the dust cup into the drill bit. (Fig. 3) (2) Fix the drill bit to the tool holder. (Fig. 4) (3) Insert the drill bit until it hits the end of the hole, and make sure that the dust cup is not in contact with the tool holder. If the dust cup is found to be in contact with the tool holder, shift it a little forward.

HOW TO USE THE ROTARY HAMMER

1. How to drill holes (Fig. 5)

(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 shavings are freely discharged. CAUTION Although this machine is equipped with a safety 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. 6)

By applying the drill bit 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. 7)

(1) Loosen the side handle and insert the straight portion of the stopper into the handle bolt hole. (2) Move the stopper to the specified position and rotate the side handle clockwise to fix the stopper.

Position the end of the bit so makes contact with the concrete, turn on the switch and perform the warming up operation. Make sure that a hitting sound is produced and then use the unit. CAUTION When the warming up operation is performed, hold the side handle and the main unit securely with both hands to maintain a secure grip and avoid being turned around by the drill.

DRILLING AND DRIVING-IN OPERATIONS FOR

ANCHORS Use the optional accessories for anchors, such as anchor adapter and taper shank adapter.

1. When a rotation striking anchor adapter is used.

(1) Install the self-drilling anchor in the anchor adapter (Fig. 9). (2) Turn ON the switch and drill a base hole with the self- drilling anchor. (Fig. 10) At the start of the hole-drilling slightly tilt the Rotary Hammer to determine the hole position. (3) After cleaning out dust with a syringe, attach the plug to the anchor tip and drive in the anchor with a manual hammer. (4) After driving in the anchor, use the drift key to separate the anchor. (Fig. 11) (5) By employing a manual hammer or pliers, snap off the tapered portion of the anchor. (Fig. 12) CAUTION Since the snapped-off tapered portion will fly about, pay attention to the snapping direction.

2. When a taper shank adapter is used. (Fig. 13)

(1) Install drill bit with taper shank in the taper shank adapter. (2) Turn the power on and drill a base hole to the depth sounded by indicating groove on the drill bit. (3) After cleaning out dust with a syringe, attach the plug to the anchor tip and drive in the anchor with a manual hammer. (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 rest. (Fig. 14)

HOW TO HANDLE A CORE BIT

When a core bit is used, large caliber holes and blind holes can be drilled. In this case, use optional accessories for core bits (such as a center pin and core bit shank) for more rational operation.

CAUTION Prior to mounting a core bit, always disconnect the plug from the receptacle. (1) Mount the core bit on the core bit shank. (Fig. 15) Before that, feed oil to the screw portion of core bit shank for easy dismount. (2) Mount the core bit shank on the drill main body in the same manner as in mounting the drill bit and the bull point. (Fig. 16) (3) Insert the center pin into the guide plate until it reaches the extremity. (4) Fit in the guide plate by aligning its concaved portion with the core bit tip. When the position of the concave is shifted by turning the guide plate right or left, the guide plate never slips off even when the drill is used in a downward direction. (Fig. 17)

(1) Insert the plug into a receptacle. (2) A spring is built in the center pin. By straightly and gently pressing it to the wall or floor surface, the entire surface of the core bit tip attains contact to start the hole drilling job. (Fig. 18) (3) When the hole depth reaches approximately 5 mm, the hole position can be determined. Then remove the center pin and guide plate from the core bit and continue the hole drilling job. CAUTION When removing the center pin and guide plate, always disconnect the plug from the receptacle.

3. How to dismount the core bit

(1) By holding the drill (with the core bit inserted) in an upward position, drive the drill to repeat impact operation two or three times, whereby the screw is loosened and the drill becomes ready for disassembly. (Fig. 19) (2) Remove the core bit shank from the drill, hold the core bit with one hand, and strongly strike the head of the hexagonal portion of the core bit shank with a hand hammer two or three times, whereby the round head screw is loosened and the drill is ready for disassembly. (Fig. 20)

HOW TO REPLACE GREASE

This machine is of full air-tight construction to protect against dust and to prevent lubricant leakage. Therefore, the machine can be used without lubrication for long periods. Replace the grease as described below.

1. Grease replacement period

After purchase, replace grease after every 6 months of usage. Ask for grease replacement at the nearest authorized Hitachi Service Agent. Proceed for replacement of grease.

2. Grease replacement

CAUTION Before replacing the grease, turn the power off and pull out the power plug. (1) Remove the crank case cover and wipe off the grease inside. (Fig. 21) (2) Supply 20g of Hitachi Electric Hammer Grease A (Standard accessory, contained in tube) to the crank case. As the tube contain 30g of grease, supply 2/3 of the contained grease. (3) After replacing the grease, install the crank case cover securely. NOTE The Hitachi Electric Hammer Grease A is of the low viscosity type. If necessary purchase from an authorized Hitachi Service Agent. 01Eng_DH45SA_WE_6L 6/28/07, 12:228English

1. Inspecting the tool

Since use of a dull tool will degrade efficiency and cause possible motor malfunction, sharpen or replace the tool as soon as 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 (Fig. 22)

The Motor employs carbon brushes which are consumable parts. When they become worn to or near the “wear limit”, it could result in motor trouble. When an auto-stop carbon brush is equipped, the motor will stop automatically. At that time, replace both carbon brushes with new ones which have the same carbon brush Numbers shown in the figure. In addition, always keep carbon brushes clean and ensure that they slide freely within the brush holders.

5. Replacing carbon brushes

Loosen the tapping screws and remove the brush cap cover. Then, remove the brush caps and take out the carbon brushes. After replacement, be sure to fasten the brush caps and fix the brush cap cover firmly using the tapping screws.
