5FUNCTIONAL 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.Switch actionCAUTION:• Before plugging in the tool, always check to seethat the switch trigger actuates properly and returnsto the "OFF" position when released.For tool without lock button and lock-off buttonFig.2To start the tool, simply pull the switch trigger. Releasethe switch trigger to stop.For tool with lock buttonFig.3To 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.ASSEMBLYCAUTION:• Always be sure that the tool is switched off andunplugged before carrying out any work on the tool.Removing or installing planer bladesFig.4CAUTION:• 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.To remove the blades on the drum, unscrew the fiveinstallation bolts with the hex 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.Fig.5There are two adjusting screws for each blade. Wheninstalling the blade, the notch in the blade should fit overthe head of the adjusting screw. Then fit on the drumcover and secure all the installation bolts onlyfinger-tight.Turn the drum until the blade edge is right in the middlebetween the front and rear bases.Place the triangular rule flat on the rear base and run itout over and across the blade edge. Turn the twoadjusting screws to adjust the blade protrusion. Theblade setting should be made so that the protrusion willbe uniform all the way across. Thus the triangular ruleshould be flush with the entire width of the blade edge.After adjusting both blades, tighten all the installationbolts evenly and alternately with the wrench.Fig.6After tightening the bolts, secure the adjusting screwsfully.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.
