[. . . ] Before using the machine on an actual workpiece, let it run for a while. Watch for vibration or wobbling that could indicate poor installation or a poorly balanced blade. Shut off power and wait for saw blade to stop before servicing or adjusting machine. Be alert at all times, especially during repetitive, monotonous operations. [. . . ] Empty the dust bag of its contents, tapping it lightly so as to remove particles adhering to the insides which might hamper further collection. CAUTION: Before plugging in the machine, always check to see that the switch trigger actuates properly and returns to the ``OFF'' position when released. 10) To prevent the trigger from being accidentally pulled, a lock-off button is provided. If the kerf groove has not yet been cut in the kerf board by the factory, you should cut the groove before actually using the machine to cut a workpiece. Switch on the machine and lower the blade gently to cut a groove in the kerf board. WARNING: It is extremely important to always secure the workpiece properly and tightly with the vise. Also, after a cutting operation, DO NOT raise the blade until the blade has come to a complete stop. When the diameter of the blade has been reduced due to sharpening, adjust the depth adjusting bolt by turning it with the socket wrench. The saw blade is lowered by turning the depth adjusting bolt counterclockwise and raised by turning it clockwise. Adjust so that when the handle is in the fully lowered position, there will be a distance of about 126 mm from the front face of the guide fence to the point where the front edge of the blade enters the kerf. With the machine unplugged, rotate the blade by hand while holding the handle all the way down. Be sure that the blade does not contact any part of the lower base when the handle is lowered completely. When cutting with this machine, the thickness of the blade is cut out of the workpiece as well. Therefore, your cutting line should be on either the left or right side of the groove in the kerf board. Switch on the machine and wait until the blade attains full speed before lowering gently into the cut. When the blade contacts the workpiece, gradually bear down on the handle to perform the cut. When the cut is completed, switch off the machine and WAIT UNTIL THE BLADE HAS COME TO A COMPLETE STOP before returning the blade to its fully elevated position. A thin piece of cut off material could otherwise contact the coasting blade and be thrown around dangerously. CAUTION: When cutting long workpieces, use supports that are as high as the top surface level of the turn base. When you have moved the grip to the position where the pointer indicates the desired angle on the miter scale, securely tighten the grip clockwise. CAUTION: When turning the turn base, be sure to raise the handle fully. Attach a wood facing to the guide fence using the holes in the guide fence. [. . . ] Square the side of the blade with the face of the guide fence using a triangular rule, try-square, etc. Then securely tighten the hex bolts on the guide fence in the order indicated in Fig. Damage attributable to normal wear and tear, overload or improper handling will be excluded from the guarantee. In case of complaint, please send the machine, undismantled, with the enclosed GUARANTEE CERTIFICATE, to your dealer or the Makita Service Center. [. . . ]
