17 ENGLISHFor tool with the inner flange forother than 15.88 mm hole-diametersaw bladeThe inner flange has a certain diameter protrusion onone side of it and a different diameter protrusion on theother side. Choose a correct side on which protrusionfits into the saw blade hole perfectly. Mount the innerflange onto the mounting shaft so that the correct sideof protrusion on the inner flange faces outward and thenplace saw blade and outer flange.► Fig.22: 1. Mounting shaft 2.

Slipping your handfrom the hex wrench can cause a personal injury.WARNING: Make sure that the protrusion "a"on the inner flange that is positioned outside fitsinto the saw blade hole "a" perfectly. Mounting theblade on the wrong side can result in the dangerousvibration.For tool with the inner flange for a15.88 mm hole-diameter saw blade(country specific)Mount the inner flange with its recessed side facingoutward onto the mounting shaft and then place circu-lar saw blade (with the ring attached if needed), outerflange and hex bolt.For tool without the ring► Fig.23: 1.

RingWARNING: BE SURE TO TIGHTEN THE HEXBOLT CLOCKWISE SECURELY. Also be carefulnot to tighten the bolt forcibly. Slipping your handfrom the hex wrench can cause a personal injury.WARNING: If the ring is needed to mount theblade onto the spindle, always be sure that thecorrect ring for the blade's arbor hole you intendto use is installed between the inner and the outerflanges. Use of the incorrect arbor hole ring mayresult in the improper mounting of the blade causingblade movement and severe vibration resulting inpossible loss of control during operation and in seri-ous personal injury.Blade guard cleaningWhen changing the circular saw blade, make sure toalso clean the upper and lower blade guards of accu-mulated sawdust as discussed in the Maintenancesection. Such efforts do not replace the need to checklower guard operation before each use.Connecting a vacuum cleanerOptional accessoryWhen you wish to perform clean cutting operation,connect a Makita vacuum cleaner to your tool. Connecta hose of the vacuum cleaner to the dust nozzle usingthe front cuff 24.► Fig.25: 1. Hose of the vacuum cleaner 2. Front cuff24 3. Dust nozzleAdjusting angle of dust nozzleThe angle of the dust nozzle can be adjusted by rotatingthe dust nozzle.When operating the tool without connecting a vacuumcleaner, bring the dust nozzle downward to prevent theoperator from being exposed to sawdust.When operating the tool with connecting a vacuumcleaner, bring the dust nozzle upward to keep the hoseof the vacuum cleaner from getting caught in the work-piece or the guide rail.► Fig.26: 1. Dust nozzleOPERATIONThis tool is intended to cut wood products only.Refer to our website or contact your local Makita dealerfor the correct circular saw blades to be used for thematerial to be cut.Do not use the tool without the sub base unless whenusing the guide rail.Checking blade guard functionRemove the battery cartridge.Set the bevel angle to 0°, and then retract the lowerguard manually to the end and release it. The lowerguard is properly functioning if;— it is retracted above the base without any hin-drance and;— it automatically returns and contacts with thestopper.► Fig.27: 1. Upper guard 2.
