[. . . ] Make sure the blade is not contacting the workpiece before the switch is turned on. Always switch off and wait for the blades to come to a complete stop before any adjusting. When leaving the planer, switch off and set it with the front base up on a wooden block, so that the blades do not contact anything. [. . . ] 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. cAUTION: Tighten the blade installation bolts carefully when attaching the blades to the machine. 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. 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 power planer keeps cutting at a speed that will not result in jamming by chips. [. . . ] Use of the special nozzle assembly will minimize chip scatter, making for a cleaner work area. 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. [. . . ]
