• Hold power tool by insulated gripping surfaces when performing an operation where the cutting accessory may contact hidden wiring. Cutting accessory contacting a “live” wire may make exposed metal parts of the power tool “live” and could give the operator an electric shock.
• Use clamps or another practical way to secure and support the workpiece to a stable platform. Holding the work by hand or against your body leaves it unstable and may lead to loss of control.
• Always use safety glasses or goggles. Ordinary eye or sun glasses are NOT safety glasses.
• Avoid cutting nails. Inspect workpiece for any nails and remove them before operation.
• Do not cut oversize workpiece.
• Check for the proper clearance beyond the workpiece before cutting so that the blade will not strike the floor, workbench, etc.
• Hold the tool firmly.
• Make sure the blade is not contacting the workpiece before the switch is turned on.
• Keep hands away from moving parts.
• Do not leave the tool running. Operate the tool only when hand-held.
• Always switch off and wait for the blade to come to a complete stop before removing the blade from the workpiece.
• Do not touch the blade or the workpiece immediately after operation; they may be extremely hot and could burn your skin.
• Do not operate the tool at no-load unnecessarily.
• Some material contains chemicals which may be toxic. Take caution to prevent dust inhalation and skin contact. Follow material supplier safety data.
• Always use the correct dust mask/respirator for the material and application you are working with.
• WARNING: DO NOT let comfort or familiarity with product (gained from repeated use) replace strict adherence to safety rules for the subject product. MISUSE or failure to follow the safety rules stated in this instruction manual may cause serious personal injury.

(Reference numbers correspond to diagram elements in the PDF: 1. Base, 2. Bolt, 3. Hex wrench)

Cutouts can be made with either of two methods A or B:

A) Boring a starting hole:

• For internal cutouts without a lead-in cut from an edge, pre-drill a starting hole (1) 12 mm (1/2″) or more in diameter.
• Insert the blade into this hole to start your cut.

B) Plunge cutting:

You need not bore a starting hole or make a lead-in cut if you carefully do as follows:

1. Tilt the tool up on the front edge of the base with the blade point positioned just above the workpiece surface.
2. Apply pressure to the tool so that the front edge of the base will not move when you switch on the tool and gently lower the back end of the tool slowly.
3. As the blade pierces the workpiece, slowly lower the base of the tool down onto the workpiece surface.
4. Complete the cut in the normal manner.

(Reference number corresponds to diagram elements in the PDF: 1. Starting hole)

To trim edges or make dimensional adjustments, run the blade lightly along the cut edges.

Always use a suitable coolant (cutting oil) when cutting metal. Failure to do so will cause significant blade wear. The underside of the workpiece can be greased instead of using a coolant.

CAUTION: Always be sure that the tool is switched off and the battery cartridge is removed before installing or removing accessories.

When repeatedly cutting widths of 160 mm (6-5/16″) or less, use of the rip fence will assure fast, clean, straight cuts.

1. Insert the rip fence (1 or 3) into the rectangular hole on the side of the tool base with the fence guide facing down.
2. Slide the rip fence to the desired cutting width position.
3. Tighten the bolt (2) with the hex wrench (1) to secure it.

(Reference numbers correspond to diagram elements in the PDF: 1. Rip fence / Hex wrench, 2. Bolt, 3. Fence guide)

CAUTION: Always be sure that the tool is switched off and the battery cartridge is removed before installing or removing accessories.

When cutting circles or arcs of 170 mm (6-11/16″) or less in radius, install the rip fence as follows:

1. Insert the rip fence into the rectangular hole on the side of the base with the fence guide (1) facing up.
2. Insert the circular guide pin (3) through either of the two holes on the fence guide.
3. Screw the threaded knob (2) onto the pin to secure the pin.
4. Slide the rip fence to the desired cutting radius.
5. Tighten the bolt (from the straight cut setup) to secure it in place.
6. Move the base all the way forward.

NOTE: Always use blades No. B-17, B-18, B-26 or B-27 when cutting circles or arcs.

(Reference numbers correspond to diagram elements in the PDF: 1. Fence guide, 2. Threaded knob, 3. Circular guide pin)

CAUTION: Always be sure that the tool is switched off and the battery cartridge is removed before attempting to perform inspection or maintenance.

• Never use gasoline, benzine, thinner, alcohol or the like for cleaning. Discoloration, deformation or cracks may result.
• To maintain product SAFETY and RELIABILITY, repairs, any other maintenance or adjustment should be performed by Makita Authorized or Factory Service Centers, always using Makita replacement parts.
