User manual MAKITA MS4510

[. . . ] If both hands are holding the saw, they cannot be cut by the blade. The guard cannot protect you from the blade below the workpiece. Adjust the cutting depth to the thickness of the workpiece. Less than a full tooth of the blade teeth should be visible below the workpiece. [. . . ] For all other sawing, the lower guard should operate automatically. Always observe that the lower guard is covering the blade before placing saw down on bench or floor. An unprotected, coasting blade will cause the saw to walk backwards, cutting whatever is in its path. To check lower guard, open lower guard by hand, then release and watch guard closure. Also check to see that retracting handle does not touch tool housing. Leaving blade exposed is VERY DANGEROUS and can lead to serious personal injury. Use extra caution when cutting damp wood, pressure treated lumber, or wood containing knots. Maintain smooth advancement of tool without decrease in blade speed to avoid overheating the blade tips. Do not attempt to remove cut material when blade is moving. Wait until blade stops before grasping cut material. Inspect for and remove all nails from lumber before cutting. €¢ Use only the Makita wrench to install or remove the blade. To remove the blade, press the shaft lock so that the blade cannot revolve and use the hex wrench to loosen the hex bolt counterclockwise. Then remove the hex bolt, outer flange and blade. 9) Mount the inner flange with its recessed side facing outward onto the mounting shaft and then place saw blade, outer flange and hex bolt. 10) The inner flange has a certain diameter protrusion on one side of it and a different diameter protrusion on the other side. Choose a correct side on which protrusion fits into the saw blade hole perfectly. Next, mount the inner flange onto the mounting shaft so that the correct side of protrusion on the inner flange faces outward and then place saw blade and outer flange. bE SURE TO TIGHTEN THE HEX BOLT CLOCKWISE SECURELY. CAUTION: • Make sure that the protrusion “a” on the inner flange that is positioned outside fits into the saw blade hole “a” perfectly. Mounting the blade on the wrong side can result in the dangerous vibration. When changing blade, make sure to also clean upper and lower blade guards of accumulated sawdust. [. . . ] To get clean cuts, keep your sawing line straight and your speed of advance uniform. If the cut fails to properly follow your intended cut line, do not attempt to turn or force the tool back to the cut line. Doing so may bind the blade and lead to dangerous kickback and possible serious injury. Release switch, wait for blade to stop and then withdraw tool. [. . . ]
