MAINTENANCE AND INSPECTION CAUTION: Pull out battery before doing any inspection or maintenance. 1. Inspecting the saw blade: Since use of a dull saw blade will degrade efficiency and cause possible motor malfunction, sharpen or replace the saw blade as soon as abrasion is noted. CAUTION: If a dull saw blade is used, reactive force is increased during cutting operation. Avoid the use of the dull saw blade without repair. 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. 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 whthin the brush holders. NOTE: When replacing the carbon brush with a new one, be sure to use the Hitachi Carbon Brush Code No. 999058. 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. 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. 6. Performance checkup and maintenance of safety cover Keep the safety cover in good shape for smooth performance at all times. Be sure to make prompt repair in case of any malfunction. 7. Adjusting the base and saw blade to maintain perpendicularity: The angle between the base and the saw blade has been adjusted to 90°, however should this perpendicularity be lost for some reason, adjust in the following manner: (1) Turn the base face up (Fig. 29) and loosen the knob and wing-nut. (2) Apply a square to the base and the saw blade and turning the slotted set screw with a slotted-head screwdriver, shift the position of the base to produce the desired right angle. 8. Check for dust Dust may be removed with a clean rag or a cloth dampened with soapy water. Do not use bleach, chlorine, gasoline or thinner, for they may damage the plastics. 9. Storage Storing in a place below 40°C and out of the reach of children. 10. Service and repairs All quality power tools will eventually require servicing or replacement of parts because of wear from normal use. To assure that only genuine replacement parts must be used, all service and repairs must be performed by a HITACHI AUTHORIZED SERVICE CENTER, ONLY. 11. Service parts list A : Item No. B : Code No. C : No. Used D : Remarks CAUTION: Repair, modification and inspection of Hitachi Power Tools must be carried out by an 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 (i.e. code numbers and/or design) may be changed without prior notice.
