2. General Safety Instructions

Always observe basic safety precautions to reduce the risk of fire, electric shock, and personal injury when operating power tools. Keep this manual for future reference.

• Work Area Safety: Keep the work area clean and well-lit. Cluttered or dark areas invite accidents. Do not operate power tools in explosive atmospheres, such as in the presence of flammable liquids, gases, or dust.
• Electrical Safety: Power tool plugs must match the outlet. Never modify the plug in any way. Avoid body contact with earthed or grounded surfaces, such as pipes, radiators, ranges, and refrigerators.
• Personal Safety: Always wear eye protection. Use hearing protection when operating for extended periods. Dress properly; avoid loose clothing or jewelry. Secure long hair.
• Tool Use and Care: Do not force the power tool. Use the correct power tool for your application. Disconnect the plug from the power source before making any adjustments, changing accessories, or storing power tools.
• Maintenance: Maintain power tools. Check for misalignment or binding of moving parts, breakage of parts, and any other condition that may affect the power tool’s operation.

3. Component Identification

Familiarize yourself with the various parts of your jig saw for safe and effective operation.

• Barrel Grip: Ergonomically designed for close-to-work cutting and enhanced control.

• Base Plate: Die-cast aluminum base, adjustable for bevel cuts.
• LED Light: Illuminates the cutting surface for improved visibility.
• Dust Blower: Clears the line of cut from debris.
• Variable Speed Control Dial: Adjusts the strokes per minute (SPM) for different materials.
• Orbital Setting Lever: Selects between straight cutting and three orbital cutting modes.
• Tool-less Blade Change System: Allows for quick and easy blade installation and removal.
• On-board Hex Wrench: Stored on the tool for convenient bevel adjustments.

4. Setup and Adjustments

4.1 Blade Installation and Removal

The Makita 4351FCT features a patented tool-less blade change system for quick and easy blade management.

1. Ensure the tool is unplugged from the power source.
2. To install a blade, push the blade into the blade holder until it clicks into place. Ensure the blade teeth face forward.
3. To remove a blade, pull the blade release lever (if present, otherwise refer to specific tool mechanism) and carefully pull the blade out. Be cautious as the blade may be hot after use.

4.2 Base Plate Adjustment for Bevel Cuts

The die-cast aluminum base can be adjusted for bevel cuts up to 45 degrees to the right or left, with a positive stop at 90 degrees for standard straight cuts.

1. Unplug the tool.
2. Locate the hex bolt securing the base plate. Use the on-board hex wrench to loosen this bolt.
3. Tilt the base plate to the desired angle, using the angle markings for guidance.
4. Tighten the hex bolt securely to lock the base plate in position.

5. Operating Instructions

5.1 Powering On/Off and Speed Control

The jig saw is equipped with a 6.3 AMP motor and electronic variable speed control.

• To turn the tool on, press the power switch. To turn it off, release the switch.
• Adjust the cutting speed using the variable speed control dial, located on the tool body. The speed range is 800 to 2,800 Strokes Per Minute (SPM). Select a lower speed for harder materials or intricate cuts, and a higher speed for softer materials or faster cutting.

5.2 Orbital Settings

The jig saw offers three orbital settings plus a straight cutting mode to optimize cutting performance for different materials and desired finishes.

• Setting "0" (Straight Cut): For fine, precise cuts in all materials, especially metals and plastics, where minimal chipping is desired.
• Settings "I", "II", "III" (Orbital Cuts): These settings introduce an oscillating motion to the blade, increasing cutting aggression and speed. Higher orbital settings are suitable for faster cuts in softer materials like wood, where a rougher finish is acceptable.
• Adjust the orbital setting using the lever located near the blade.

5.3 Cutting Procedure

Before cutting, ensure the workpiece is securely clamped. The built-in LED light and dust blower enhance visibility of the cutting line.

1. Mark your cutting line clearly on the workpiece.
2. Place the front edge of the base plate flat on the workpiece, ensuring the blade is clear of the material.
3. Start the jig saw and allow it to reach full speed before engaging the blade with the material.
4. Guide the tool along the cutting line with steady, even pressure. Do not force the tool; let the blade do the work.
5. For plunge cuts, refer to advanced cutting techniques or use a pilot hole.

6. Maintenance

Regular maintenance ensures the longevity and safe operation of your jig saw.

• Cleaning: After each use, unplug the tool and clean dust and debris from the ventilation openings and around the blade area using a soft brush or compressed air.
• Blade Inspection: Regularly inspect blades for sharpness and damage. Replace dull or damaged blades immediately.
• Cord Inspection: Check the power cord for any cuts, abrasions, or damage. If damaged, have it repaired by a qualified service technician.
• Base Plate: Keep the base plate clean and free of obstructions to ensure smooth gliding over the workpiece.
• Storage: Store the tool in a dry, secure location out of reach of children.
