9To install the blades, first clean out all chips or foreignmatter adhering to the drum or blades. Use blades of thesame dimensions and weight, or drum oscillation/vibrationwill result, causing poor planing action and, eventually,tool breakdown.Place the blade on the gauge base so that the blade edgeis perfectly flush with the inside edge of the gauge plate.Place the adjusting plate on the blade, then simply pressin the heel of the adjusting plate flush with the back side ofthe gauge base and tighten two screws on the adjustingplate. Now slip the heel of the adjusting plate into thedrum groove, then fit the drum cover on it.Tighten all the installation bolts evenly and alternately withthe socket wrench.For tool with mini planer blades1. Remove the existing blade, if the tool has been in use,carefully clean the drum surfaces and the drum cover.To remove the blades on the drum, unscrew the threeinstallation bolts with the socket wrench. The drumcover comes off together with the blades. (Fig. 7)2. To install the blades, loosely attach the adjusting plateto the set plate with the pan head screws and set themini planer blade on the gauge base so that thecutting edge of the blade is perfectly flush with theinside flank of the gauge plate. (Fig. 8)3. Set the adjusting plate/set plate on the gauge base sothat the planer blade locating lugs on the set plate restin the mini planer blade groove, then press in the heelof the adjusting plate flush with the back side of thegauge base and tighten the pan head screws.4. It is important that the blade sits flush with the insideflank of the gauge plate, the planer blade locating lugssit in the blade groove and the heel of the adjustingplate is flush with the back side of the gauge base.Check this alignment carefully to ensure uniformcutting.5. Slip the heel of the adjusting plate into the groove ofthe drum.6. Set the drum cover over the adjusting plate/set plateand screw in the three hex flange head bolts so that agap exists between the drum and the set plate to slidethe mini planer blade into position. The blade will bepositioned by the planer blade locating lugs on the setplate. (Fig. 9)7. The blade's lengthwise adjustment will need to bemanually positioned so that the blade ends are clearand equidistant from the housing on one side and themetal bracket on the other.8. Tighten the three hex flange head bolts (with thesocket wrench provided) and rotate the drum to checkclearances between the blade ends and the tool body.9. Check the three hex flange head bolts for finaltightness.10. Repeat procedures 1 - 9 for other blade.For the correct planer blade settingYour planing surface will end up rough and uneven,unless the blade is set properly and securely. The blademust be mounted so that the cutting edge is absolutelylevel, that is, parallel to the surface of the rear base.Refer to some examples below for proper and impropersettings.(A) Front base (Movable shoe)(B) Rear base (Stationary shoe)Change of chip discharge direction(Fig. 10)Chip discharge direction can be changed to the right orleft. To change the direction, pull out the stopper whileturning it slightly backward and fit in it in one of twoopenings on the opposite side of chip discharge so thatthe recessed part fits to protrusion. (Fig. 11)Dust bag (accessory) (Fig. 12)Attach the dust bag onto the chip discharge opening.Correct setting Although this side view cannot show it, theedges of the blades run perfectly parallel tothe rear base surface.Nicks in surface Cause: One or both blades fails to have edgeparallel to rear base line.Gouging at start Cause: One or both blade edges fails toprotrude enough in relation to rearbase line.Gouging at end Cause: One or both blade edges protrudestoo far in relation to rear base line.(A) (B)(B)(A)(A) (B)
