Most accidents that result from power tool operation and maintenance are caused by the failure to observe basic safety rules or precautions. An accident can often be avoided by recognizing a potentially hazardous situation before it occurs, and by observing appropriate safety procedures. Basic safety precautions are outlined in the “SAFETY” section of this Instruction Manual and in the sections which contain the operation and maintenance instructions. Hazards that must be avoided to prevent bodily injury or machine damage are identified by WARNINGS on the power tool and in this Instruction Manual. NEVER use this power tool in a manner that has not been specifically recommended by HITACHI.

MEANINGS OF SIGNAL WORDS

WARNING indicates a potentially hazardous situations which, if ignored, could result in death or serious injury. CAUTION indicates a potentially hazardous situations which, if not avoided, may result in minor or moderate injury, or may cause machine damage. NOTE emphasizes essential information. SAFETY

Read all safety warnings and all instructions. Failure to follow the warnings and instructions 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.

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.

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. 01Eng_H45FRV_US 9/18/12, 8:533English

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 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, 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 dust collection 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 and/or the battery pack 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. 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 different from those 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.

Exposure to noise can cause hearing loss.

underground wiring. Touching live wiring or electric cable with this tool may result in electric shock. Confirm before use whether hidden objects are present, such as electric cables within the wall, floor or ceiling.

OPERATION To ensure safer operation of this power tool, HITACHI has adopted a double insulation design. “Double insulation” means that two physically separated insulation systems have been used to insulate the electrically conductive materials connected to the power supply from the outer frame handled by the operator. Therefore, either the symbol “ ” or the words “Double insulation” appear on the power tool or on the nameplate. Although this system has no external grounding, you must still follow the normal electrical safety precautions given in this Instruction Manual, including not using the power tool in wet environments. To keep the double insulation system effective, follow these precautions:

Only HITACHI AUTHORIZED SERVICE CENTER should disassemble or assemble this power tool, and only genuine HITACHI replacement parts should be installed.

Clean the exterior of the power tool only with a soft cloth moistened with soapy water, and dry thoroughly. Never use solvents, gasoline or thinners on plastic components; otherwise the plastic may dissolve. 01Eng_H45FRV_US 9/18/12, 8:535English

OPERATION APPLICATIONS 䡬 Demolishing concrete, chiseling concrete, grooving, bar cutting, and driving piles. Application examples: Installation of piping and wiring, sanitary facility installation, machinery installation, water supply and drainage work, interior jobs, harbor facilities and other civil engineering work.

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

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

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

WARNING: Damaged cord must be replaced or repaired.

4. Check the receptacle

If the receptacle only loosely accepts the plug, the receptacle must be repaired. Contact a licensed electrician to make appropriate repairs. If such a faulty receptacle is used, it may cause overheating, resulting in a serious hazard.

5. Confirming condition of the environment:

Confirm that the work site is placed under appropriate conditions conforming to prescribed precautions.

6. Select the number of strikes (Fig. 8)

CAUTION: Do not make any adjustment of the dial during operation. Holding the main body with one hand can swing you around, resulting in an injury. 01Eng_H45FRV_US 9/18/12, 8:539English

This machine has an electronic controlled circuit built-in, enabling stepless regulation of the number of strikes. Make the most of this machine by adjusting the dial according to the working contents; chiseling, demolishing, or the quality of the material to be chiseling or demolishing. The scale “1” of the dial is for the minimum speed with 1600 strikes per minute, and the scale “5” is for the maximum speed with 3000 strikes per minute.

HOW TO USE THE DEMOLITION HAMMER

1. After placing the tip of the tool on concrete surface, switch

ON. The switch can be turned ON if the trigger is pulled and OFF when it is released. If the stopper is pressed while the trigger for the switch is pulled, even if your finger is released from the trigger, the switch remains ON - convenient for continuous operation. To turn the switch OFF, pull the trigger again, and then the stopper comes off.

2. By utilizing the empty weight of the machine and by firmly

holding the hammer by both hands, you can effectively control the subsequent recoil motion. Proceed at a moderate work-rate, the use of too much pushing force will impair efficiency.

3. Even when the switch is on, the motor is running and the tool head is pressed to the

demolition surface, the hammer sometimes does not start operating. In these instances, turn the switch off, press the tool head against the demolition surface again, and turn the switch on and off. This should start the hammer operating. Repeat this procedure for several minutes, and the hammer will heat, after which it will operate when switched to ON-LOCK. Moreover, the hammer heats after several minutes of use with the dial set to a small number. The hammer will now operate in any position when switched to ON-LOCK. CAUTION: After long time of use, the cylinder case becomes hot. Therefore, be careful not to burn your hands. Fig. 9 Standard number of strikes Dial Number of strikes/min.

WARNING: Be sure to switch power OFF and disconnect the plug from the

receptacle during maintenance and inspection.

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 screws

Regularly inspect all screws and ensure that they are properly tightened. Should any of the screws be loosened, retighten them immediately.

WARNING: Using this demolition hammer with loosened screws is extremely

3. Inspecting the carbon brushes (Fig. 10)

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. NOTE: Use HITACHI carbon brush No. 73 indicated in Fig. 10.

4. Replacing carbon brushes (Refer to figure for name of parts.)

Loosen the set screw then remove the tail cover. By loosening the brush caps, the carbon brushes can be removed. After fitting new carbon brushes, properly retighten the brush caps and mount the tail cover.
