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, 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. Installing Tools 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, cutters, etc., make sure to use the genuine parts designated by our company. (1) Clean the shank portion of the tool. (2) Insert the tool in a twisting manner into the tool holder until it latches itself. (Fig. 1, 2) (3) Check the latching by pulling on the tool. (Fig. 3) 5. Deciding Working Position of Tool The tool can be turned every 30 degrees and can be fixed at the position of 12 steps. (1) As shown in Fig. 4, grip (B) is turned 60 degrees in the direction of A, the blade angle can be changed freely to any desired position. (Fig. 5) (2) As shown in Fig. 6, return grip (B) in the direction of A, and make sure that it is locked completely. 6. Removing Tool As shown in Fig. 7, pull front cap in the direction of A, and pull out the tool. (Fig. 8) HOW TO USE THE HAMMER (Fig. 9) 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. Impact rate of the tool can be controlled steplessly by varying the amount that the trigger switch is pulled. 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. GREASE REPLACEMENT This machine is of fully oil sealed construction to protect against dust incursion and to prevent lubricant leakage. 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 Hitachi 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) Disassemble the crank cover and thoroughly wipe off the old grease inside. (Fig. 10) (2) Supply 30g (the standard volume to cover the connecting rod) of Hitachi Electric Hammer Grease A in the crank case. (3) After replacing the grease, reassemble the 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 authorized Hitachi Service Center. MAINTE...
