Power Source Single-Phase, 115 V 60 Hz Current 12.8 A Capacity Drill Bit: 2" (50 mm) Core Bit: 6-1/4" (160 mm) No-Load Speed 120 – 250/min Full-load Blow 1200 – 2500 bpm Weight 21.6 lbs (9.8 kg) English ASSEMBLY AND OPERATION APPLICATIONS Rotation and hammering function . Drilling anchor holes . Drilling holes in concrete Hammering function only . Crushing concrete, chipping, digging, and squaring (by applying optional accessories) PRIOR TO OPERATION 1. Power source Ensure that the power source to be utilized conforms to the power source requirements specified on the product nameplate. 2. Power switch 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. 3. Extension cord When the work area is far away from the power source, use an extension cord of sufficient thickness and rated capacity (refer to page 9). 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 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. (1) Clean, then smear the tool shank with the grease provided in the green tube. English (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. Releasing the grip reverts the grip and secures the tool in place. (3) To remove the tool, fully pull the grip in Front Cap the direction of the arrow and pull out the tool. 7. Regulating the number of rotations and hammering (Fig. 3) This hammer drill is equipped with a built-in electronic control circuit that can adjust and regulate the number of rotations and times of hammering. This Fig. 2 hammer drill 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 1,200 times of blow per minute. The scale ‘5’ is designed for a maximum speed with the number of 250 rotations per minute and 2,500 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. Tool Part of SDS max Shank Grip 5 Dial Fig. 3 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. 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 Fig. 5 motor rotation, the tool can start to rotate abruptly, resulting in unexpected accidents. Be sure to switch the selector Selector Lever Undercover lever when the motor is at a complete stop. (1) Switching to “rotation + hammering” (a) Pull the selector lever, release lock and turn it clockwise. (b) Align of the selector lever with ^ on the side of the undercover as illustrated in Fig. 6. (c) Push in the selector lever to lock it. NOTE: Turn the selector lever (do not pull it up) to check if it is completely locked and make sure t...
