SPECIFIC SAFETY RULES

DO NOT let comfort or familiarity with the product (gained from repeated use) replace strict adherence to jig saw safety rules. If you use this tool unsafely or incorrectly, you can suffer serious personal injury.

1. Hold power tools by insulated gripping surfaces when performing an operation where the cutting accessory may contact hidden wiring or its own cord. Cutting accessory contacting
   • a “live” wire may make exposed metal parts of the power tool “live” and could give the operator an electric shock.
2. 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.
3. Always use safety glasses or goggles. Ordinary eye or sunglasses are NOT safety glasses.
4. Avoid cutting nails. Inspect the workpiece for any nails and remove them before operation.
5. Do not cut oversize workpieces.
6. Check for the proper clearance beyond the workpiece before cutting so that the blade will not strike the floor, workbench, etc.
7. Hold the tool firmly.
8. Make sure the blade is not contacting the workpiece before the switch is turned on.
9. Keep hands away from moving parts.
10. Do not leave the tool running. Operate the tool only when hand-held.
11. Always switch off and wait for the blade to come to a complete stop before removing the blade from the workpiece.
12. Do not touch the blade or the workpiece immediately after operation; they may be extremely hot and could burn your skin.
13. Do not operate the tool at no-load unnecessarily.
14. Some material contains chemicals that may toxic.
15. Take caution to prevent dust inhalation and skin contact. Follow material supplier safety data.
16. Always use the correct dust mask/respirator for the material and application you are working with.

SAVE THESE INSTRUCTIONS

WARNING:
MISUSE or failure to follow the safety rules stated in this instruction manual may cause serious personal injury.
FUNCTIONAL DESCRIPTION
CAUTION:

• Always be sure that the tool is switched off and unplugged before adjusting or checking the function of the tool.

Selecting the cutting action (Fig. 1) This tool can be operated with an orbital or a straight line (up and down) cutting action. The orbital cutting action thrusts the blade forward on the cutting stroke and greatly increases cutting speed. To change the cutting action, just turn the cutting action changing lever to the desired cutting action position. Refer to the table to select the appropriate cutting action.

0

| Straight-line cutting action| For cutting mild steel, stainless steel and plastics. For clean cuts in wood and plywood.
I| Small orbit-cutting action| For cutting mild steel, aluminum and hard wood.

II

| Medium orbit cutting action| For cutting wood and plywood.

For fast cutting in aluminum and mild steel.

III| Large orbit-cutting action| For fast cutting in wood and plywood.

Switch action (Fig. 2)
CAUTION:

• Before plugging in the tool, always be sure that the tool is switched off.
• To start the tool, slide the switch lever to the “I” position.
• To stop the tool, slide the switch lever to the “O” position.

Speed adjusting dial (Fig. 3) For 4351CT, 4351FCT: The tool speed can be infinitely adjusted between 800 and 2,800 strokes per minute by turning the adjusting dial. Higher speed is obtained when the dial is turned in the direction of number 5; lower speed is obtained when it is turned in the direction of number 1. Refer to the table to select the proper speed for the workpiece to be cut. However, the appropriate speed may differ with the type or thickness of the workpiece. In general, higher speeds will allow you to cut workpieces faster but the service life of the blade will be reduced.

CAUTION:

• The speed-adjusting dial can be turned only as far as 5 and back to 1. Do not force it past 5 or 1, or the speed-adjusting function may no longer work. The tools equipped with electronic functions are easy to operate because of the following features.

Constant speed control
Electronic speed control for obtaining constant speed. Possible to get a fine finish, because the rotating speed is kept constant even under load conditions.
Soft start feature
Safety and soft start because of suppressed starting shock.
Lighting up the lamps For 4351FCT only
CAUTION:

• Do not look in the light or see the source of light directly.
• To turn on the lamp, pull the trigger. Release the trigger to turn it off.

NOTE:

• Use a dry cloth to wipe the dirt off the lens of the lamp. Be careful not to scratch the lens of a lamp, or it may lower the illumination.

ASSEMBLY

CAUTION:

• Always be sure that the tool is switched off and unplugged before carrying out any work on the tool.Installing or removing saw blade (Fig. 4, 5 & 6)

CAUTION:

• Always clean out all chips or foreign matter adhering to the blade and/or blade holder. Failure to do so may cause insufficient tightening of the blade, resulting in a serious personal injury.
• Do not touch the blade or the workpiece immediately after the operation; they may be extremely hot and could burn your skin.
• Tighten the saw blade securely. Failure to do so may cause a serious injury.
• When you remove the saw blade, be careful not to hurt your fingers with the top of the blade or the tips of the workpiece. To install the blade, open the tool opener to the position shown in the figure. (Fig. 4)
• Keeping that situation, insert the saw blade into the blade clamp as far as the two protrusions of the blade can not be seen. (Fig. 5) Return the tool opener to its original position. After installing, always make sure that the blade is securely held in place by trying to pull it out.

CAUTION:

• Do not open the tool opener excessively, or it may cause tool damage.
• To remove the blade, open the tool opener to the position shown in the figure. Pull the saw blade out toward the base. (Fig. 6)

NOTE:

• Occasionally lubricate the roller.
• Hex wrench storage (Fig. 7)

OPERATION

CAUTION:

• Hold the tool firmly with one hand on the switch handle and the other hand on the front grip when performing the tool.
• Always hold the base flush with the workpiece. Failure to do so may cause blade breakage, resulting in a serious injury.
• Turn the tool on and wait until the blade attains full speed. Then rest the tool base flat on the workpiece and gently move the tool forward along the previously marked cutting line. When cutting curves, advance the tool very slowly. (Fig. 8)

Bevel cutting
CAUTION:

• Always be sure that the tool is switched off and unplugged before tilting the base. With the base tilted, you can make bevel cuts at any angle between 0° and 45° (left or right). (Fig. 9) Loosen the bolt on the back of the base with the hex wrench. Move the base so that the bolt is positioned in the center of the bevel slot in the base. (Fig. 10) Tilt the base until the desired bevel angle is obtained. The V-notch of the gear housing indicates the bevel angle by graduations. Then tighten the bolt firmly to secure the base. (Fig. 11)
• Front flush cuts (Fig. 12)
  Loosen the bolt on the back of the base with the hex wrench, and slide the base all the way back. Then tighten the bolt to secure the base.

Cutouts
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 12 mm or more in diameter. Insert the blade into this hole to start your cut. (Fig. 13)

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. (Fig. 14)
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.

Finishing edges (Fig. 15) To trim edges or make dimensional adjustments, run the blade lightly along the cut edges.
Metal cutting
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.
Dust extraction
The dust nozzle (accessory) is recommended to perform clean cutting operations.
To attach the dust nozzle to the tool, insert the hook of
the dust nozzle into the hole in the base. (Fig. 16 & 17)
The dust nozzle can be installed on either the left or right side of the base.
Then connect a Makita vacuum cleaner to the dust nozzle. (Fig. 18)

CAUTION:

• If you try to remove the dust nozzle forcibly, the hook of the dust nozzle can be diminished and removed unintentionally during operation.

Rip fence set (optional accessory)
CAUTION:
• Always be sure that the tool is switched off and unplugged before installing or removing accessories.

Straight cuts (Fig. 19 & 20)When repeatedly cutting widths of 160 mm or less, use of the rip fence will assure fast, clean, straight cuts. To install, insert the rip fence into the rectangular hole on the side of the tool base with the fence guide facing down. Slide the rip fence to the desired cutting width position, then tighten the bolt to secure it.
Circular cuts (Fig. 21 & 22)
When cutting circles or arcs of 170 mm or less in radius, install the rip fence as follows. Insert the rip fence into the rectangular hole on the side of the base with the fence guide facing up. Insert the circular guide pin through either of the two holes on the fence guide. Screw the threaded knob onto the pin to secure the pin. Now slide the rip fence to the desired cutting radius, and tighten the bolt to secure it in place. Then move the base all the way forward.
NOTE:

• Always use blade No. B-17, B-18, B-26, or B-27 when cutting circles or arcs.

Guide rail adapter set (accessory)
When cutting parallel and uniform width or cutting straight, the use of the guide rail and the guide rail adapter will assure the production of fast and clean cuts. (Fig. 23) To install the guide rail adapter, insert the rule bar into the square hole of the base as far as it goes. Secure the bolt with the hex wrench securely. (Fig. 24) Install the guide rail adapter on the rail of the guide rail. Insert the rule bar into the square hole of the guide rail adapter. Put the base to the side of the guide rail, and secure the bolt securely. (Fig. 25) CAUTION:

• Always use blades No. B-8, B-13, B-16, B-17 or 58 when using the guide rail and the guide rail adapter. Cover plate (Fig. 26)
• Use the cover plate when cutting decorative veneers, plastics, etc. It protects sensitive or delicate surfaces from damage. Fit it on the back of the tool base. Anti-splintering device (Fig. 27)

For splinter-free cuts, the anti-splintering device can be used. To install the anti-splintering device, move the tool base all the way forward and fit it from the back of tool base. When you use the cover plate, install the anti- splintering device onto the cover plate.

CAUTION:

• The anti-splintering device cannot be used when making bevel cuts.
