When too strong power is used, the screw head may be broken or be injured. Be sure to adjust the cap position according to the screw diameter. (2) Tightening torque indication (See Fig. 23) The tightening torque differs depending on the type of screw and the material being tightened. The unit indicates the tightening torque with the numbers “1, 4, 7 ... 22” on the cap, and a black dot. The tightening torque at position “1” is the weakest and the torque is strongest at the highest number. (3) Adjusting the tightening torque (See Fig. 23) Rotate the cap and line up the numbers “1, 4, 7 ... 22” on the cap, or the black dot, with the triangle mark on the outer body. Adjust the cap in the weak or the strong torque direction according to the torque you need. CAUTION: . The motor rotation may be locked to cease while the unit is used as drill. While operating the driver drill, take care not to lock the motor. . When setting the shift knob to “HIGH” (high speed) and the position of the cap is between “16” and “22”, it may happen that the clutch does not engaged and that the motor is locked. In such a case, please set the shift knob to “LOW” (low speed). . If the motor is locked, immediately turn the power off. If the motor is locked for a while, the motor or battery may be burnt. . Too long hammering may cause the screw broken due to excessive tightening. . A buzzing noise is produced when the motor is about to rotate; this is only a noise, not a machine failure. 12. For drilling into brick CAUTION: . When the Cordlless hammer drill is used continuously, the body may be heated. If this happens, leave the Cordlless hammer drill to cool. . Excessive pressing force never increases drilling speed. It will not only damage the drill tip or reduce working efficiency, but could also shorten the service life of drill bit. Operate Cordlless hammer drill within 20 – 30 lbs. (10 – 15 kg) pressing force while drilling into brick. English THE SCOPE AND SUGGESTIONS FOR USES Table 6 Work Cap position Suggestions Drilling Brick Use for drilling purpose. Wood Use for drilling purpose.Steel Aluminum Screw tightening Small screw 1 – 22 Use the bit and socket matching the screw diameter. Wood screw 1 – Use after drilling a pilot hole. CAUTION: . While operating the Cordless hammer drill, take care not to lock the motor. If the motor is locked, immediately turn the power off. If the motor is locked for a while, the motor or battery will be burnt. . Do not tighten too strongly as the screw heads will be damaged. English MAINTENANCE AND INSPECTION CAUTION: Pull out battery before doing any inspection or maintenance. 1. Checking the condition of the bit The bits should be checked regularly. If worn or broken bits can slip or decrease the efficiency of the motor and burn it out. Replace worn bits with new ones. CAUTION: If you use a driver bit of which point is worn or broken, it will be dangerous since it slips. So replace it with a new one. 2. Check the Screws Loose screws are dangerous. Regularly inspect them and make sure they are tight. CAUTION: Using this power tool with loosened screws is extremely dangerous. 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. 25) The motor employs carbon brushes which are consumable parts. Since and excessively worn carbon brush can result in motor trouble, replace the carbon brush with new ones 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. NOTE: When replacing the carbon brush with a new one, be sure to use the Hitachi Carbon Brush Code No. 999054. 5. Replacing carbon brushes Take out the carbon brush by first removing the brush cap and then hooking the protrusion of the carbon brush with a flat head screw driver, etc., as shown in Fig. 27. When installing the carbon brush, choose the direction so that the nail of the carbon brush agrees with the contact portion outside the brush tube. Then push it in with a finger as illustrated in Fig. 28. Lastly, install the brush cap. Wear limit 0.12" (3 mm) 0.45" (11.5 mm) Fig. 25 Nail of carbon brush Protrusion of carbon brush Fig. 26 Fig. 27 English CAUTION: . Be absolutely sure to insert the nail of the carbon brush into the contact portion outside the brush tube. (You can insert whichever one of the two nails provided.) . Caution must be exercised since any error in this operation can result in the deformed nail of the carbon brush and may cause motor trouble at an early stage. Fig. 28 6. Check for Dust Dust may be removed with a soft cloth or a cloth dampened with soapy water. Do not use bleach, chlorine, gasoline or thinner, for they may damage the plastics. 7. Disposal of the exhausted battery WARNING: Do not dispose of the exhausted battery. The battery must explode if it is i...
