30. OPERATE POWER TOOLS AT THE RATED VOLTAGE. Operate the power tool at voltages specified on their nameplates. If using the power tool at a higher voltage than the rated voltage, it will result in abnormally fast motor revolution and may damage the unit and burn out the motor. 31. NEVER USE A TOOL WHICH IS DEFECTIVE OR OPERATING ABNORMALLY If the tool appears to be operating unusually, making abnormal noises, or otherwise appears defective, stop using it immediately and arrange for repairs by a Hitachi authorized service center. 32. NEVER LEAVE TOOL RUNNING UNATTENDED. TURN POWER OFF. Don’t leave tool until it comes to a complete stop. 33. CAREFULLY HANDLE POWER TOOLS. Should a power tool be dropped or struck against hard materials inadvertently it may be deformed, cracked, or damaged. 34. DO NOT WIPE PLASTIC PARTS WITH SOLVENT. Solvents such as gasoline, thinner, benzine, carbon tetrachloride, and alcohol may damage and crack plastic parts. Do not wipe them with such solvents. Wipe plastic parts with a soft cloth lightly dampened with soapy water and dry thoroughly. 35. WHEN REPLACING A COMPONENT PART, ADOPT THE SAME TYPE. When replacing a component part with a new one, adopt the same type of new part. Also, never attempt to repair a power tool yourself. 36. KEEP GUARDS IN PLACE AND IN WORKING ORDER. Never wedge of tie lower guard open. Check operation of lower guard before each use. Do not use if lower guard dose not close briskly over saw blade. CAUTION: If saw is dropped, lower guard may be bent, restricting full return. English 37. KEEP BLADES CLEAN AND SHARP. Sharp blades minimize stalling and kickback. 38. DANGER: KEEP HANDS AWAY FROM CUTTING AREA. Keep hands away from blades. Do not reach underneath work while blade is rotating. Do not attempt to remove cut material when blade is moving. CAUTION: Blades coast after turn off. 39. SURRPORT LARGE PANELS. Large panels must be supported as shown in Fig. 1 to minimize the risk of blade pinching and kickback. When cutting operation requires the resting of saw on the work piece, the saw shall be rested on the larger portion and the smaller piece cut off. To avoid kickback, do support board Don't support board or panel away or panel near the cut. from the cut. Fig. 1 Fig. 2 40. USE RIP FENCE. Always use a fence or straight edge guide when ripping. 41. WARNING: It is important to support the work piece properly and to hold the saw firmly to prevent loss of control which could cause personal injury. Fig. 3 illustrates typical hand support of the saw. When operating the saw, keep the cord away from the cutting area and position it so that it will not be caught on the work piece during the cutting operation. A TYPICAL ILLUSTRATION OF PROPER HAND SUPPORT. WORK PIECE SUPPORT, AND SUPPLY CORD ROUTING Fig. 3 42. GUARD AGAINST KICKBACK. Kickback occurs when the saw stalls rapidly and is driven back towards the oprator. Release switch immediately if blade binds or saw stalls. English 8 Keep blades sharp. Support large panels as shown in Fig. 1. Use fance or straight edge guide when ripping. Don't fence tool. Stay alert exercise control. Don't remove saw from work during a cut while the blade is moving. 43. LOWER GUARD. Raise lower guard with the retracing handle (Lever). 44. ADJUSTMENTS. Before cutting be sure depth and bevel adjustments are tight. 45. USE ONLY CORRECT BLADES IN MOUNTING. Do not use blade with incorrect size holes. Never use defective or incorrect blade washers or bolts. 46. AVOID CUTTING NAILS. Inspect for and remove all nails from work piece before cutting. 47. DO NOT RUN THE SAW WHILE CARRYING IT AT YOUR SIDE. 48. 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. 4 illustrates the RIGHT way to cut off the end of board, and Fig. 5 the WRONG way. If the work piece is short or small, clamp is down. DON’T TRY TO HOLD SHORT PLACES BY HAND! Fig. 4 Fig. 5 49. Use extra caution when making a “Pocket Cut” into existing walls or other blind areas. The protruding blade may cut objects that can cause KICKBACK. NEVER place your hand or fingers behind the saw. If kickback occurs, the saw could easily jump backwards over your hand, possibly causing severe injury. Fig. 6 Vise Vise English 50. Before setting the tool down after completing a cut, be sure that the lower (telescoping) guard has closed and the blade has come to a complete stop. 51. Never attempt to saw any material like metal and so on that give off sparks. Such action can lead to fire or injury. 52. Never attempt to saw with the circular saw held upside down in a vise. This is extremely dangerous and can lead to serious accidents. (Fig. 7) Fig. 7 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 will be used, all service and repairs must be perfor...
