[. . . ] 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. Make sure the blade is not contacting the workpiece before the switch is turned on. Wait until the blade attains full speed before cutting. [. . . ] It is important that the blade sits flush with the inside flank of the gauge plate, the planer blade locating lugs sit in the blade groove and the heel of the adjust plate is flush with the back side of the gauge base. Check this alignment carefully to ensure uniform cutting. Set the drum cover over the adjust plate/set plate and screw in the three hex flange head bolts so that a gap exists between the drum and the set plate to slide the mini planer blade into position. The blade's lengthwise adjustment will need to be manually positioned so that the blade ends are clear and equidistant from the housing on one side and the metal bracket on the other. Tighten the three hex flange head bolts (with the socket wrench provided) and hand rotate the drum to check clearances between the blade ends and the machine body. Check the three hex flange head bolts for final tightness. Repeat procedures 1 ­ 9 for other blade. 7) The blade edge should be made to protrude outside slightly (0. Otherwise, nicks and generally poor shiplapping results. cAUTION: Tighten the blade installation bolts carefully when attaching the blades to the machine. A loose installation bolt can be dangerous. Always check to see they are tightened securely. Your planing surface will end up rough and uneven, unless the blade is set properly and securely. The blade must be mounted so that the cutting edge is absolutely level, that is, parallel to the surface of the rear base. Below are some examples of proper and improper settings. Although this side view cannot show it, the edges of the blades run perfectly parallel to the rear base surface. Cause: One or both blade edges fails to protrude enough in relation to rear base line. Cause: One or both blade edges protrudes too far in relation to rear base line. Depth of cut may be adjusted by simply turning the knob on the front of the machine. First, rest the machine front base flat upon the workpiece surface without the blades making any contact. Apply pressure on the front of machine at the start of planing, and at the back at the end of planing. Planing will be easier if you incline the workpiece in stationary fashion, so that you can plane somewhat downhill. [. . . ] The nozzle assembly may be attached after the chip cover on the machine body is removed. When slipping on the assembly, fit the pin on it into the rear cover hole. Use the chip cover screws to fasten it in place. For standard blades only Always keep your blades sharp for the best performance possible. [. . . ]
