[. . . ] This enables better control of the power tool in unexpected situations. G) If devices are provided for the connection of dust extraction and collection facilities, ensure these are connected and properly used. The correct power tool will do the job better and safer at the rate for which it was designed. B) Do not use the power tool if the switch does not turn it on and off. [. . . ] It is important to support the work properly to minimize body exposure, blade binding, or loss of control. E) Hold power tool by insulated gripping surfaces when performing an operation where the cutting tool may contact hidden wiring or its own cord. Contact with a "live" wire will also make exposed metal parts of the power tool "live" and shock the operator. This improves the accuracy of cut and reduces the chance of blade binding. G) Always use blades with correct size and shape (diamond versus round) of arbour holes. Blades that do not match the mounting hardware of the saw will run eccentrically, causing loss of control. The blade washers and bolt were specially designed for your saw, for optimum performance and safety of operation. Never use any abrasive wheels Burst of abrasive wheel cause serious injury of operator or persons around the working area. Do not operate the saw if lower guard does not move freely and close instantly. Raise the lower guard with the retracting handle and make sure it moves freely and does not touch the blade or any other part, in all angles and depth of cut. If the guard and the spring are not operating properly, they must be serviced before use. The riving knife is ineffective in preventing kickback during short cuts. Do not use saw blades which do not comply with the characteristics specified in these instructions. *Be sure to check the nameplate on product as it is subject to change by areas. Adjusting the guide piece On the circular saw, it is possible to make fine adjustment of the fixing position of the guide piece, where the saw blade and the premarked line are to be aligned. When the saw is shipped from the factory, the linear portion of a front scale on the guide piece is aligned with the central position of the saw blade (Fig. Loosen the fixed M4 screw on the guide piece, should the fixing position be wrong, and make necessary adjustment of the position. Using the dust collector To use the vacuum cleaner to gather up saw dust, attach the suction hose to the dust collector which is attached to the main unit by M4 and M5 screws. When attaching the dust collector always be sure to change the lever to the short type at this same time (Fig. CAUTION Continuing to use the lever that was attached to the main unit prior to shipping from the factory will cause it to bind on the dust collector and will interfere with the lower guard operation. Power source Ensure that the power source to be utilized conforms to the power requirements specified on the product nameplate. If the plug is connected to a receptacle while the power switch is in the ON position, the power tool will start operating immediately, which could cause a serious accident. [. . . ] MODIFICATION Hitachi Power Tools are constantly being improved and modified to incorporate the latest technological advancements. CAUTION To avoid serious accident, ensure the switch is in the OFF position, and the power source is disconnected. (2) Depress the lock lever, lock the spindle, and remove the hexagonal-socket bolt with the Hex. (3) While holding the lower guard lever to keep the lower guard fully retracted into the saw cover, remove the saw blade. [. . . ]
