User manual MAKITA 5103R

[. . . ] When cutting operation requires the resting of the saw on the work piece, the saw shall be rested on the larger portion and the smaller piece cut off. Check operation of lower guard before each use. Don't use if lower guard does not close briskly over saw blade. CAUTION: If saw is dropped, lower guard may be bent, restricting full return. [. . . ] Before cutting be sure depth and bevel adjustments are tight. Don't use blades with incorrect size holes. Inspect for and remove all nails from lumber before cutting. When operating the saw, keep the cord away from the cutting area and position it so that it will not be caught on the workpiece during the cutting operation. Operate with proper hand support, proper workpiece support, and supply cord routing away from the work area. WARNING: It is important to support the workpiece properly and to hold the saw firmly to prevent loss of control which could cause personal injury. Never attempt to saw with the circular saw held upside down in a vise. This is extremely dangerous and can lead to serious accidents. 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. The following blade can be used with this tool. Do not use saw blades which do not comply with the characteristics specified in these instructions. Do not use saw blades the disc of which is thicker or the set of which is smaller than the thickness of the riving knife. To remove the saw blade, depress the shaft lock fully to prevent shaft rotation, then use the hex wrench to loosen the hex socket head bolt. 1) Now remove the outer flange, raise the safety cover as much as possible, and remove the saw blade. 2) Install the saw blade using the reverse of the removal procedure. Install the inner flange, saw blade, outer flange and hex socket head bolt, in that order. Be sure to secure the hex socket head bolt tightly with the shaft lock fully depressed. Make sure that the blade teeth point forward in the same direction as the tool rotation (the arrow on the blade should point in the same direction as the arrow on the tool). Never depress the shaft lock while the saw is running. Use the socket wrench to loosen the hex head socket bolt for the riving knife adjustment, then raise the safety cover. Move the riving knife up or down over the two protuberances for settings indicated in the illustration, so as to obtain the proper clearance between the riving knife and saw blade. CAUTION: Ensure that the riving knife is adjusted such that: The distance between the riving knife and the toothed rim of the saw blade is not more than 5 mm. [. . . ] To prevent the switch trigger from being accidentally pulled, a lock-off button is provided. Before plugging in the tool, always check to see that the switch trigger actuates properly and returns to the ``OFF'' position when released. Set the base plate on the workpiece to be cut without the blade making any contact. Then turn the tool on and wait until the blade attains full speed. [. . . ]
