WARNING: When mounting the saw blade, confirm that the rotation indicator mark on the saw blade and the rotation direction of the saw cover (see Fig. 1) are properly matched. (4) Thoroughly clean washer (C) and the bolt, and install them onto the saw blade spindle. (5) Press in the spindle lock and tighten the bolt by turning it to the left by 10mm box wrench as indicated in Fig. 37-b. CAUTION: * Confirm that the spindle lock has returned to the retract position after installing or removing the saw blade. * Tighten the bolt so it does not come loose during operation. Confirm the bolt has been properly tightened before the power tool is started. 2. Dismounting the saw blade Dismount the saw blade by reversing the mounting procedures described in paragraph 1 above. The saw blade can easily be removed after lifting the safety covers. CAUTION: Never attempt to install saw blades larger than 8-1/2" (216mm) in diameter. Always install saw blades that are 8-1/2" (216mm) in diameter or less. MAINTENANCE AND INSPECTION WARNING:To avoid an accident or personal injury, always confirm that the trigger switch is turned OFF and the power plug has been disconnected from the receptacle before performing any maintenance or inspection of this tool. 1. Inspecting the saw blade Always replace the saw blade immediately upon the first sign of deterioration or damage. A damaged saw blade can cause personal injury and a worn saw blade can cause ineffective operation and possible overload to the motor. CAUTION: Never use a dull saw blade. When a saw blade is dull, its resistance to the hand pressure applied by the tool handle tends to increase, making it unsafe to operate the power tool. 2. Adjusting a loose slide pipe (2) Properly tighten the 8mm nut after completing these adjustment. Slide Pipe (A) Fig. 38 43 1/4" (6mm) No. 43 indicates the last two numbers of carbon11/16" (17mm) 43 1/4" (6mm) No. 43 indicates the last two numbers of carbon11/16" (17mm) English 3. Inspecting the carbon brushes (Fig. 39 and Fig. 40) The carbon brushes in the motor are expendable parts. If the carbon brushes become excessively worn, motor trouble might occur. Therefore, inspect the carbon brushes periodically and replace them when they have become worn to the wear limit line as shown in Fig. 39. Also, keep the carbon brushes clean so that they will slide smoothly within the brush holders. The carbon brushes can easily be removed after removal of the brush caps (see Fig. 40) with a slotted (minus) screwdriver.

Re-tighten mounting screws on any loose part. WARNING: To prevent personal injury, never operate the power tool if any components are loose. 5. Inspecting the safety covers for proper operation Before each use of the tool, test the safety covers (see Fig. 7) to assure that they are in good condition and that they move smoothly. Never use the tool unless the safety covers operate properly and it is in good mechanical condition. 6. Storage After operation of the tool has been completed, check that the following has been performed: (1) Trigger switch is in OFF position, (2) Power plug has been removed from the receptacle, (3) Lock-off button has been removed and stored in a secure place. When the tool is not in use, keep it stored in a dry place out of the reach of children. 7. Handle (for transportation and carrying) For transportation purpose, grasp the handle with one hand and hold the base at the left end grip section with the other to carry. NOTE: Before transporting or carrying, position saw blade against guard and tighten slide securing knob to stop slide motion. 8. Lubrication Lubricate the following sliding surfaces once a month to keep the power tool in good operating condition for a long time (see Fig. 1 and Fig. 2). Use of machine oil is recommended. Oil supply points: *Rotary portion of hinge *Rotary portion of vise assembly *Sliding portion of slide pipe (A) and slide pipe (B) Fig. 41Base Guard Slide Securing Knob Handle for Transportation Blade English 9. Cleaning Periodically remove chips, dust and other waste material from the surface of the power tool, especially from the inside of the safety cover and sub cover with a damp, soapy cloth. To avoid a malfunction of the motor, protect it from contact with oil or water. 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 authorized replacement parts will be used and that the double insulation system will be protected, all service (other than routine maintenance) must be performed by an AUTHORIZED HITACHI POWER TOOL REPAIR CENTER ONLY. NOTE: Specifications are subject to change without any obligation on the part of HITACHI. Francais INFORMATIONS IMPORTANTES Lire et assimiler toutes les instructions de fonctionn...
