11• Always use a front grip and rear handle and firmly holdthe tool by both front grip and rear handle duringoperations. (Fig. 26)Hold the tool firmly. The tool is provided with both a frontgrip and rear handle. Use both to best grasp the tool. Ifboth hands are holding saw, they cannot be cut by theblade. Set the base on the workpiece to be cut without theblade making any contact. Then turn the tool on and waituntil the blade attains full speed. Now simply move thetool forward over the workpiece surface, keeping it flatand advancing smoothly until the sawing is completed.To get clean cuts, keep your sawing line straight and yourspeed of advance uniform. If the cut fails to properly followyour intended cut line, do not attempt to turn or force thetool back to the cut line. Doing so may bind the blade andlead to dangerous kickback and possible serious injury.Release switch, wait for blade to stop and then withdrawtool. Realign tool on new cut line, and start cut again.Attempt to avoid positioning which exposes operator tochips and wood dust being ejected from saw. Use eyeprotection to help avoid injury.Rip fence (Guide rule) (optionalaccessory) (Fig. 27)The handy rip fence allows you to do extra-accuratestraight cuts. Simply slide the rip fence up snugly againstthe side of the workpiece and secure it in position with theclamping screw on the front of the base. It also makesrepeated cuts of uniform width possible.MAINTENANCECAUTION:• Always be sure that the tool is switched off and thebattery cartridge is removed before carrying out anywork on the tool.• Clean out the upper and lower guards to ensurethere is no accumulated sawdust which mayimpede the operation of the lower guardingsystem. A dirty guarding system may limit the properoperation which could result in serious personal injury.The most effective way to accomplish this cleaning iswith compressed air. If the dust is being blown out ofthe guards be sure the proper eye and breathingprotection is used.• Never use gasoline, benzine, thinner, alcohol or thelike. Discoloration, deformation or cracks may result.Adjusting for accuracy of 0° and 45° cut(vertical and 45° cut) (Fig. 28 & 29)This adjustment has been made at the factory. But if it isoff, adjust the adjusting screws with a hex wrench whileinspecting 0° or 45° the blade with the base using atriangular rule or square rule, etc. Use the 45° stopper foradjusting 45° angle.Adjusting bevel guide (Fig. 30)The bevel guide has been factory adjusted. But if it is off,you can adjust it as the following procedure.To adjust the bevel guide, loosen the two screws. Alignthe 0° line on the bevel guide with the guide on the basewhen the base is set to 0° angle.To maintain product SAFETY and RELIABILITY, repairs,any other maintenance or adjustment should beperformed by Makita Authorized Service Centers, alwaysusing Makita replacement parts.OPTIONAL ACCESSORIESCAUTION:• These accessories or attachments are recommendedfor use with your Makita tool specified in this manual.The use of any other accessories or attachments mightpresent a risk of injury to persons.
