If a square block is utilized as a workbench, select level ground to ensure it is properly stabilized. An unstable workbench will result in hazardous operation. Base Work piece Saw bladeWorkbench Fig. 2 CAUTION: To avoid possible accident, always ensure that the portion of work piece remaining after cutting is securely anchored or held in position. 7. Check if lever (A)s are tightened. If the lever (A) to adjust cutting depth (Fig. 3) and lever (A) to adjust angle of inclination (Fig. 4) are loose, injury can result. Make sure that they are tightened securely. 8. Check performance of safety cover WARNING: Make absolutely sure that the safety cover is not fixed. Also, check and see if it can move smoothly. If the saw blade is kept exposed injury can result. The lower guard (refer to Fig. 1) serves to protect your body from coming into contact with the saw blade. Make absolutely certain that the cover smoothly performs to cover the saw blade. If the safety cover should not move smoothly, never use it without repairing it. In such a case, get in touch with the store where you bought the circular saw or the HITACHI Authorized Service Center for necessary repair. 9. Eye protection When you use the tool, make certain that you wear eye protection. 10. Check if saw blade is tightened Refer to [mounting and dismounting the saw blade] in Page 12, and make sure that the flange bolt is tightened securely. 11. Check for proper operation of the brake. Your saw has an automatic electric brake which is designed to stop the blade from coasting in about 3 seconds, after you release the trigger switch. It is useful when making certain cuts in wood where a coasting blade would result a wide imprecise cut. Occasionally, under certain conditions, the brake will not function properly and won't stop the saw in the 3 seconds discussed above. If this condition persists, turn the saw on and off four or five times. If the brake still does not stop the blade in about 3 seconds, the problem may be worn brushes. Replace the brushes and try the saw again. If the problem still persists, have the tool serviced at a HITACHI AUTHRIZED SERVICE CENTER. English ADJUSTSING THE SAW PRIOR TO USE WARNING: To avoid serious accidents, ensure the switch is in OFF position, and disconnect the plug from the receptacle. 1. Adjusting the cutting depth (Fig. 3) WARNING: If the lever (A) is loose, injury can result. Tighten it securely after adjustment. To adjust cutting depth, loosen the lever (A) and, while holding the base with one hand, move the main body up and down to obtain the prescribed cutting depth. After adjusting to the prescribed cutting depth, tighten the lever (A) securely. Lever (A) Tighten Loosen Base Fig. 3 2. Adjusting the angle of inclination WARNING: If the lever (A) is loose, injury can result. Tighten it securely after adjustment. You can incline saw blade from 0° to a maximun angle of 55° in relation to the base. As shown in Fig. 4 by loosing the lever (A) on the bevel scale, the saw blade may be inclined to an angle of 45° in relation to the base. Lever (A) 0° – 45° Fig. 4 If you use inclination angle of over 45°, as shown in Fig. 5 move the lever (A) to inside, the saw blade may be inclined to a maximum angle of 55° in relation to the base. Always ensure that the lever (A) is thoroughly tightened after making the desired adjustment. 45° – 55° Fig. 5 3. Regulating the guide (Rip fence) (Fig. 6, 7) ................................................ Optional Accessory Install the wing bolt (B) and lock spring on the base. Insert the guide into the base, move it left and right and adjust the cutting position. Tighten the wing bolt (B) and fix the guide. The guide can be installed either from the left or the right side of the main body. Wing bolt (B) Lock spring Base Fig. 6 English 10 . Place the wider portion of the saw base on that part of the work piece which is solidly supported, not on the section that will fall off when the cut is made. As examples, Fig. 11 illustrates the RIGHT way to cut off the end of board, and Fig. 12 the WRONG way. If the work piece is short or small, clamp it down. DON’T TRY TO HOLD SHORT PLACES BY HAND! Wing bolt (B), Lock spring Base Guide (Rip fence) Fig. 11 Don't support board or panel away from the cut. Fig. 10 Fig. 9 To avoid kickback, do support board or panel near the cut. Fig. 8 Fig. 7 CUTTING PROCEDURES WARNING: . Do not use any abrasive wheels. . Never touch the moving parts. . As shown in Fig. 8, be sure to hold the round handle securely with both hands when cutting. Contact with "live" wire will make exposed metal parts of the power tool "live" and shock the operator. In addition, make sure to secure the work piece with a clamp when cutting. . Should the saw blade be stopped or make an abnormol noise during operation, turn off the switch immediately. . Don't remove circular saw from work piece during a cut while the saw blade is moving. . Support large panels to minimize the risk of blade pinchin...
