6injury.FUNCTIONAL DESCRIPTIONCAUTION:• Always be sure that the tool is switched off andunplugged before adjusting or checking function onthe tool.Adjusting depth of cutFig.1Depth of cut may be adjusted by simply turning the knobon the front of the tool so that the pointer points thedesired depth of cut.Switch actionFig.2CAUTION:• Before plugging in the tool, always check to seethat the switch trigger actuates properly and returnsto the "OFF" position when released.For tool with lock buttonCAUTION:• Switch can be locked in "ON" position for ease ofoperator comfort during extended use. Applycaution when locking tool in "ON" position andmaintain firm grasp on tool.To start the tool, simply pull the switch trigger. Releasethe switch trigger to stop.For continuous operation, pull the switch trigger and thenpush in the lock button.To stop the tool from the locked position, pull the switchtrigger fully, then release it.For tool with lock-off buttonTo prevent the switch trigger from being accidentallypulled, a lock-off button is provided.To start the tool, depress the lock-off button and pull theswitch trigger. Release the switch trigger to stop.FootFig.3After a cutting operation, raise the back side of the tooland a foot comes under the level of the rear base. Thisprevents the tool blades to be damaged.ASSEMBLYCAUTION:• Always be sure that the tool is switched off andunplugged before carrying out any work on the tool.Removing or installing planer bladesCAUTION:• Tighten the blade installation bolts carefully whenattaching the blades to the tool. A loose installationbolt can be dangerous. Always check to see theyare tightened securely.• Handle the blades very carefully. Use gloves orrags to protect your fingers or hands whenremoving or installing the blades.• Use only the Makita wrench provided to remove orinstall the blades. Failure to do so may result inovertightening or insufficient tightening of theinstallation bolts. This could cause an injury.For tool with conventional planer bladesFig.4Fig.5Fig.6To remove the blades on the drum, unscrew theinstallation bolts with the socket wrench. The drum covercomes off together with the blades.To install the blades, first clean out all chips or foreignmatter adhering to the drum or blades. Use blades of thesame dimensions and weight, or drumoscillation/vibration will result, causing poor planingaction and, eventually, tool breakdown.Place the blade on the gauge base so that the bladeedge is perfectly flush with the inside edge of the gaugeplate. Place the adjusting plate on the blade, then simplypress in the heel of the adjusting plate flush with the backside of the gauge base and tighten two screws on theadjusting plate. Now slip the heel of the adjusting plateinto the drum groove, then fit the drum cover on it.Tighten all the installation bolts evenly and alternatelywith the socket wrench.Repeat the above procedures for the other blade.For tool with mini planer bladesFig.71. Remove the existing blade, if the tool has been inuse, carefully clean the drum surfaces and thedrum cover. To remove the blades on the drum,unscrew the three installation bolts with the socketwrench. The drum cover comes off together withthe blades.Fig.82. To install the blades, loosely attach the adjustingplate to the set plate with the pan head screws andset the mini planer blade on the gauge base sothat the cutting edge of the blade is perfectly flushwith the inside flank of the gauge plate.3. Set the adjusting plate/set plate on the gauge baseso that the planer blade locating lugs on the setplate rest in the mini planer blade groove, thenpress in the heel of the adjusting plate flush withthe back side of the gauge base and tighten thepan head screws.4. It is important that the blade sits flush with theinside flank of the gauge plate, the planer bladelocating lugs sit in the blade groove and the heel ofthe adjusting plate is flush with the back side of thegauge base. Check this alignment carefully toensure uniform cutting.
