4. KEEP WORK AREA CLEAN. Cluttered areas and benches invite accidents. 5. DON’T USE IN DANGEROUS ENVIRONMENT. Don’t use power tools in damp or wet locations, or expose them to rain. Keep work area well lighted. Don’t use tool in presence of flammable liquids or gases. 15. DISCONNECT TOOLS before servicing; when changing accessories such as blades, bits, cutters, and the like. 16. REDUCE THE RISK OF UNINTENTIONAL STARTING. Make sure switch is in off position before plugging in. 6. KEEP CHILDREN AWAY.
VOLTAGE WARNING: Before connecting the tool to a power source (receptacle, outlet, etc.) be sure the voltage supplied is the same as that specified on the nameplate of the tool. A power source with voltage greater than that specified for the tool can result in SERIOUS INJURY to the user - as well as damage to the tool. If in doubt, DO NOT PLUG IN THE TOOL. Using a power source with voltage less than the nameplate rating is harmful to the motor. USE PROPER EXTENSION CORD.
10. Check the blade carefully for cracks or damage before operation. Replace cracked or damaged blade immediately. Gum and wood pitch hardened on blades slows saw and increases potential for kickback. Keep blade clean by first removing it from tool, then cleaning it with gum and pitch remover, hot water or kerosene. Never use gasoline to clean blade. 22. Stop operation immediately if you notice anything abnormal. 11. Use only flanges specified for this tool. 25.
SAVE THESE INSTRUCTIONS WARNING: MISUSE or failure to follow the safety rules stated in this instruction manual may cause serious personal injury.
INSTALLATION Bench mounting 001794 When the tool is shipped, the handle is locked in the lowered position by the stopper pin. Release the stopper pin by lowering the handle slightly and pulling the stopper pin. 001827 This tool should be bolted with four bolts to a level and stable surface using the bolt holes provided in the tool’s base. This will help prevent tipping and possible injury. 1 1. Stopper pin 1 1.
If the see-through blade guard becomes dirty, or sawdust adheres to it in such a way that the blade is no longer easily visible, unplug the saw and clean the guard carefully with a damp cloth. Do not use solvents or any petroleum-based cleaners on the plastic guard. 001782 1 1. Blade guard 001834 1 1. Kerf board 2. Screw 001800 2 Positioning kerf board This tool is provided with the kerf boards in the turn base to minimize tearing on the exit side of a cut.
001835 Maintaining maximum cutting capacity This tool is factory adjusted to provide the maximum cutting capacity for a 305 mm (12”) saw blade. 1 When installing a new blade, always check the lower limit position of the blade and if necessary, adjust it as follows: 1. Adjusting bolt 001540 2 1 First, unplug the tool. Lower the handle completely.
001837 Adjusting the bevel angle To adjust the bevel angle, loosen the lever at the rear of the tool counterclockwise. Push the handle to the left to tilt the saw blade until the pointer points to the desired angle on the bevel scale. Then tighten the lever clockwise firmly to secure the arm. 1 1. Lever • 001838 1 CAUTION: When tilting the saw blade, be sure to raise the handle fully. • After changing the bevel angle, always secure the arm by tightening the lever clockwise.
NEVER use the tool if it runs when you simply pull the switch trigger without pressing the lock-off button. Return tool to a Makita service center for proper repairs BEFORE further usage. • NEVER tape down or defeat purpose and function of lock-off button. Electric brake This tool is equipped with an electric blade brake. If the tool consistently fails to quickly stop blade after switch trigger release, have tool serviced at a Makita service center.
001828 To remove the blade, use the socket wrench to loosen the hex bolt holding the center cover by turning it counterclockwise. Raise the blade guard and center cover. 001829 Press the shaft lock to lock the spindle and use the socket wrench to loosen the hex bolt clockwise. Then remove the hex bolt, outer flange and blade.
001831 Dust bag The use of the dust bag makes cutting operations clean and dust collection easy. To attach the dust bag, fit it onto the dust nozzle. 1 2 When the dust bag is about half full, remove the dust bag from the tool and pull the fastener out. Empty the dust bag of its contents, tapping it lightly so as to remove particles adhering to the insides which might hamper further collection. 3 1. Dust nozzle 2. Dust bag 3.
001843 • 1 CAUTION: When performing left bevel cuts, flip the fence over to the left position as shown in the figure. Otherwise, it will contact the blade or a part of the tool, causing possible serious injury to the operator. 1. Sub-fence 001796 6 1 2 3 The vertical vise can be installed in two positions on either the left or right side of the guide fence or the holder assembly (optional accessory).
• 002247 CAUTION: Always rotate the vise nut to the right fully when securing the workpiece. Failure to do so may result in insufficient securing of the workpiece. This could cause the workpiece to be thrown, cause damage to the blade or cause the loss of control, which can result in PERSONAL INJURY. Holders and holder assembly (optional accessories) The holders and the holder assembly can be installed on either side as a convenient means of supporting workpieces horizontally.
• 001793 Gently press down the handle to perform the cut. If the handle is pressed down with force or if lateral force is applied, the blade will vibrate and leave a mark (saw mark) in the workpiece and the precision of the cut will be impaired. 1. Press cutting Secure the workpiece with the vise. Switch on the tool without the blade making any contact and wait until the blade attains full speed before lowering. Then gently lower the handle to the fully lowered position to cut the workpiece.
• When pressing the handle down, apply pressure parallel to the blade. If the pressure is not parallel to the blade during a cut, the angle of the blade might be shifted and the precision of the cut will be impaired. • Always set the sub-fence to the left position when performing left bevel cuts. 4. Compound cutting Compound cutting is the process in which a bevel angle is made at the same time in which a miter angle is being cut on a workpiece.

Outside corner (1) (2) There are crown and cove molding joints which are made to fit “Inside” 90° corners ((1) and (2) in Fig. A) and “Outside” 90° corners ((3) and (4) in Fig. A). Measuring Measure the wall length and adjust workpiece on table to cut wall contact edge to desired length.
Example: In the case of cutting 52/38° type crown molding for position (1) in Fig. A: • Tilt and secure bevel angle setting to 33.9° LEFT. • Adjust and secure miter angle setting to 31.6° RIGHT. • Lay crown molding with its broad back (hidden) surface down on the turn base with its CEILING CONTACT EDGE against the guide fence on the saw. • The finished piece to be used will always be on the LEFT side of the blade after the cut has been made.
