Contact a licensed electrician to make appropriate repairs. If such a fautly 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. How to install tool CAUTION: For tools such as a drill bit and a bull point, use only Hitachi genuine parts. English (1) Clean, then smear the tool shank with the grease provided in the green tube. (2) To attach the tool (SDS max shank), insert it into the hole until it contacts the innermost end of the hole as illustrated in Fig. 2. If you continue to turn the tool with slight pressure, you can feel a spot where there is a hitch. At that spot, pull the grip to the direction of an arrow mark and insert the tool all the way until it hits the innermost end. Tool Releasing the grip reverts the grip and secures the tool in place. Fig. 2 (3) Pull the tool to make sure it is locked completely. (4) To remove the tool, fully pull the grip in the direction of the arrow and pull out the tool. 7. Regulating the number of rotations and hammering (Fig. 3) This Rotary Hammer is equipped with a built- in electronic control circuit that can adjust and regulate the number of rotations and times of hammering. This Rotary Hammer can be used by adjusting the dial, depending upon the contents of operation, such as boring holes into fragile materials, chipping, centering, etc. The scale ‘1’ of the dial is designed for a minimum speed with the number of 120 rotations per minute and 1250 times of blow per minute. The scale ‘6’ is designed for a maximum speed with the number of 240 rotations per minute and 2500 times of blow per minute. CAUTION: Do not adjust the dial during operation. Doing so can result in injury because the Rotary Hammer must be held by only one hand, disabling the steady control of the Rotary Hammer. HOW TO USE 1. How to drill holes (Fig. 4) (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 clips are freely discharged. GripShank Front Cap Dial Fig. 3 Fig. 4 English 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 crush (Fig. 5) By applying the tool tip to the chiseling or crushing position, operate the rotary hammer by utilizing its empty weight. Forcible pressing or thrusting is unnecessary. 3. When drilling at “rotation + hammering” CAUTION: If you switch the selector lever during motor rotation, the tool can start to rotate abruptly, resulting in unexpected accidents. Be sure to switch the selector lever when the motor is at a complete stop. (1) Switching to “rotation + hammering” (a) Push the button, release lock and turn the Lever Holder selector lever clockwise. (b) Align ^ of the selector lever and of the lever holder as illustrated in Fig. 6. (c) Release the button to lock the selector lever. Fig. 5 Selector Lever Button Fig. 6 NOTE: Turn the selector lever (do not push the button) to check if it is completely locked and make sure that it does not turn. 4. When chipping and shredding at “hammering”: CAUTION: . If the selector lever is switched during motor rotation, the tool can start to rotate abruptly, resulting in unexpected accidents. Make sure to switch the selector lever when the motor is at a complete stop. . If the bull point or cold chisel is used at the position of “rotation + hammering”, the tool can start to rotate, resulting in unexpected accidents. Make sure that they are used at the positon of “hammering”. English (1) Switching to “hammering” (a) Push the button, release lock and turn the selector lever counterclockwise. (b) Align ^ of the selector lever and of the lever holder as illustrated in Fig. 7. (c) Release the button to lock the selector lever. NOTE: Turn the selector lever (do not push the button) to check if it is completely locked and make sure that it does not turn. (2) When fixing working positions of tools such as cold chisel, etc., (a) Push the button, release lock and turn the selector lever. Align ^ of the selector lever and of the lever holder as illustrated in Fig. 8. (b) Release the button to lock the selector lever. (c) Turn the grip as illustrated in Fig. 9 and fix the tool to the desired working direction. (d) Switch the selector lever to “hammering” according to the procedures mentioned in the above item (1) and secure the position of the tool. 5. Install the stopper (Fig. 10) (1) Loosen the side handle and insert the straight portion of the stopper into the handle bolt hole from the front cover. (2) Loosen the side handle, mov...
