GENERAL SAFETY RULES WARNING! Read all instructions Failure to follow all instructions listed below may result in electric shock, fi re 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 1) Work area 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. 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. 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 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 fi nger 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 toolsʼ 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. 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. 8

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 930 strikes per minute, and the scale 6 is for the maximum speed with 1650 strikes per minute. Standard number of strikes Dial Number of strikes/min. 6 1650 5 1590 4 1460 3 1320 2 1110 1 930 HOW TO USE THE DEMOLITION HAMMER (Fig. 9) 1. After placing the tip of the tool in the base hole, 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 demolition hammer with both hands, one can effectively control the subsequent recoil motion. Proceed at a moderate work-rate, the use of too much force will impair efficiency. CAUTION After long time of use, the cylinder case becomes hot. Therefore, be careful not to burn your hands. GREASE REPLACEMENT This machine is of full oil sealed construction to protect against dust and to prevent lubricant leakage. This machine can be used without grease supplement for an extended period of time. However, perform the grease replacement to maintain 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 Hitachi Authorized Service Center. In the case that you are forced to change the grease by yourself, please follow the following points. 2. How to replace grease CAUTION Before replacing the grease, turn the power off and pull out the plug from the receptacle. (1) Remove the crank case cover and crank cover and wipe off the oil grease inside. (Fig. 10) (2) Supply 80 g (the standard volume to cover the connecting rod) of Hitachi Electric Hammer Grease A to the crank case. (3) After replacing the grease, install the crank case cover and crank cover securely. At this time, do not damage or lose the oil seal. NOTE The Hitachi Electric Hammer Grease A is of the low viscosity type. When the grease is consumed, purchase from the Hitachi Authorized Service Center. MAINTENANCE AND INSPECTION CAUTION Be sure to switch power OFF and disconnect the plug from the receptacle to avoid serious trouble. 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. 10

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. 11) 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 Number shown in the figure. In addition, always keep carbon brushes clean and ensure that they slide freely within the brush holders. Genuine carbon brush service code: 999-074 5. Replacing carbon brushes Loosen the set screw and remove the tail cover. Remove the brush caps and carbon brushes. After replacing the carbon brushes, do not forget to tighten the brush caps properly and install the tail cover. 6.
