8 GENERAL SAFETY RULES 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 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. 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. 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 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. 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. 7

9 PRECAUTIONS ON USING TAPPER 1. Attach side handle and secure firmly. Using only one hand is dangerous. Be sure to attach the side handle and hold the unit firmly with both hands. If not held firmly, the reaction force that develops during tapping will spin the unit around. 2. Do not wear gloves in operating. Do not wear gloves made of stuff liable to roll up such as cotton, wool, cloth or string, etc. 3. Conform the tap to the prepared hole. Turn on the switch after the tap has been conformed to the prepared hole. Rotating the main unit with no load will waver the tap, making it difficult to conform it to the prepared hole. Also, tapping it at an angle without conforming it to the prepared hole may result in tap breakage. 4. Never touch the tap while it is rotating. Do not allow hands or any part of the body to come into contact with the tap, drill chuck or filings while the tapper unit is rotating. This could result in cuts or things being wound around the rotating parts. The tap and drill chuck will be very hot after continuous periods of tapping, so touching them may result in burns. 5. Do not release your hold of the machine while it is rotating. Never let the machine rotate unless you are holding it firmly with both hands. Allowing it to be left alone on the floor and the like while it is rotating is extremely dangerous. 6. Do not apply any unreasonable force by pressing the machine against the material. The tapping rate of this machine is determined by its number of revolution. Pressing the machine against the material will not reduce the tapping time but will cause troubles such as breaking taps and damaging threads. 7. Do not operate the machine for a long time in low speed. A powerful motor is incorporated in this machine. However, continued operation of the machine for a long time using low speed will cause an unreasonable load to be applied to the motor, possibly damaging the motor. In particular, be sure to avoid any forceful operation of the machine which will cause the tap to stop midway. Make sure to select a correct number of revolution for smooth tapping to be performed.

STANDARD ACCESSORIES (1) Chuck Wrench... 1 (2) Side Handle... 1 Standard accessories are subject to change without notice. APPLICATION Tapping with all types of steel, copper alloy and aluminum materials. 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 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 sufficient thickness and rated capacity. The extension cord should be kept as short as practicable. 4. Fixing the side handle Screw the side handle into the gear cover. 5. To hold the tap Be sure to fasten the tap tightly with a chuck wrench. There are three holes on the chuck wrench. Instead of fastening it tightly at only one hole, fasten the tap evenly at all three holes, one after another. Tap to be used (1) Only use a preceding tap or a medium tap. (2) When a 8 mm-dia. tap for which the L-length is more than 40 mm as shown in Fig. 1 is used, insert the square back end of the tap all the way into the square hole of the floating spindle as shown in Fig. 2. Next, fasten the drill chuck with the chuck handle at three sections with equal force. (3) When a slip occurs between the drill chuck and the tap when it is fastened with an 8 mm -dia. tap for which L-length is less than 40 mm as in Fig. 1 and a tap that is larger than 8 mm in dia., perform anyone of the following. 8

10 Apply cutting fluid to the tap sufficiently. First, use preceding tap. Cut a notch on the shank of a tap so that pawl of the chuck can be hooked on. (Fig. 1) Only use a tap with a smaller cutting torque (such as a spiral tap or a spiral-point tap). HOW TO USE 1. Switch operation After pulling back the trigger of the switch, depress the switch stopper. Even after the finger is removed, the switch will remain ON, proving convenient for machine continuous operation. To turn OFF the switch, by merely pulling the trigger again and releasing it, the switch stopper will be released. 2. Adjusting the number of revolution This machine incorporates an electronic control circuit which can adjust the number of tap's revolution by non-step. Adjust the dial to select the correct number of revolution, corresponding with the tap's size, the material to be tapped, and the working condition. Graduation "1" stands for the lowest speed ; and "5" for the top speed. (See Fig. 3) When graduation "1" is selected, there may be times when the machine will not rotate due to the power supply conditions. 3. To tap (1) When the tap is pressed to the hole which is to be tapped, the floating spindle is pushed into the tapper, converting the revolution to normal for tapping. While tapping, press the tap lightly to the hole. (2) When tapping is completed to the prescribed depth, pull back the tapper lightly, so that the floating spindle turns in reverse revolution and the tap comes off automatically. 4. Power to press the tapper Tapping cannot be speeded up, even if the tap is pressed beyond the necessary degree, because tapping speed is decided by the degree of revolution. Instead, it will result in breaking the tap or damaging the tap threads. Therefore, press the tapper lightly so that the floating spindle is not pushed out. 5. Conform the tap to the prepared hole. Conform the tap to the prepared hole and insert it directly in. Inserting it at an angle will exert undue stress, possible breaking the tap. 6. When tapping a blind hole, follow the procedure as shown in Fig. 4. (1) Measure the length from the head of the tap corresponding to the depth of the hole, inserting the tap into a rubber or vinyl tube leaving exactly the same length as the tap. (2) Pull back the tapper when the end of the rubber tube touches the surface of the material to be tapped, so that it then can be tapped to exactly the same depth without breaking the tap. 7. Relationship between thread diameter and prepared hole Use the specifications in Table 1 to create the most suitable prepared hole. Thread dia. Table 1 Metric coarse thread Prepared hole dia. 3 mm 2.5 ~ 2.6mm ~ ~ ~ ~ ~ Cutting fluid In order to get the sharp tap cutting and life of the tap, it is important to select cutting fluid that best suits the properties of the material to be tapped. Use of a cutting fluid will get more easy tapping. Table 2 shows the types of cutting fluids and their applications. Properties of tapped material Cast iron Steel Copper alloys Aluminum Table 2 Cutting fluid Cutting fluid is not used Rapeseed oil, non-water based cutting oil Light oil, Spindle oil Light oil CAUTION Make sure no cutting fluid is attached to the main unit. 9. Concerning drill chucks A drill chuck is fixed to the floating spindle by means of the taper attachment. In case a drill chuck should be disengaged from the unit, remove oil and dirt from the taper section of the chuck and the chuck attaching section of the spindle, let three claws of the chuck withdraw, and mount the chuck onto the floating spindle by hammering its end surface with a wooden hammer. Pay special attention to the taper section and handle it with care to prevent it from being scratched or damaged. MAINTENANCE AND INSPECTION 1. Inspecting taps Continued use of a tap with a dull cutting edge will decrease tapping efficiency and put extra load on the motor. Dull taps should replaced as quickly as possible. 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. 9

11 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. 5) The motor employs carbon brushes which are consumable parts. Since an excessively worn carbon brush can result in motor trouble, replace the carbon brush with a new one having the same carbon brush No. shown in the figure when it becomes worn to or near the wear limit. In addition, always keep carbon brushes clean and ensure that they slide freely within the brush holders. 5. Replacing carbon brushes Disassemble the brush cap with a screwdriver. The carbon brush can then easily removed. 6. Service parts list CAUTION Repair, modification and inspection of Hitachi Power Tools must be carried out by a Hitachi Authorized Service Center. This Parts List will be helpful if presented with the tool to the Hitachi Authorized Service Center when requesting repair or other maintenance. In the operation and maintenance of power tools, the safety regulations and standards prescribed in each country must be observed. MODIFICATIONS Hitachi Power Tools are constantly being improved and modified to incorporate the latest technological advancements. Accordingly, some parts may be changed without prior notice.
