• Personal Safety: Stay alert, watch what you are doing, and use common sense. Wear appropriate personal protective equipment (PPE) including safety glasses, hearing protection, dust mask, and non-skid safety shoes.
• 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.

Setup

1. Blade Installation and Removal

1. Disconnect Power: Always ensure the jigsaw is unplugged from the power source before installing or removing blades.
2. Open Blade Clamp: Locate the blade clamp lever or screw. Depending on the model, you may need a hex key or simply open a quick-release lever.
3. Insert Blade: Insert the shank of the jigsaw blade into the blade clamp, ensuring the teeth face forward. Push the blade in until it seats firmly.
4. Secure Blade: Close the blade clamp lever or tighten the screw to secure the blade. Gently pull on the blade to confirm it is locked in place.
5. Removal: Reverse the steps to remove the blade. Be cautious as the blade may be hot after use.

2. Adjusting the Base Plate (Bevel Cuts)

The base plate can be adjusted for bevel cuts at various angles.

1. Loosen Adjustment Screws: Locate the screws or levers that secure the base plate. Loosen them sufficiently to allow movement.
2. Set Angle: Tilt the base plate to the desired angle (e.g., 15°, 30°, 45°). Most jigsaws have angle markings for common settings.
3. Tighten Screws: Securely tighten the adjustment screws or levers to lock the base plate in position.
4. Return to 0°: For straight cuts, ensure the base plate is set to 0° (perpendicular to the blade) and securely tightened.

3. Connecting to Power

Ensure the power cord is in good condition and plug it into a suitable 230 Volt power outlet. Verify that the power switch is in the "OFF" position before plugging in the tool.

Operating Instructions

1. Switching On/Off

• To Start: Press the trigger switch. For continuous operation, some models may have a lock-on button.
• To Stop: Release the trigger switch. If the lock-on button is engaged, press the trigger again to release it.

2. Cutting Techniques

Always ensure the workpiece is securely clamped before cutting.

• Straight Cuts: Guide the jigsaw along a marked line, keeping the base plate flat against the workpiece. Apply steady, even pressure.
• Curved Cuts: Use a narrower blade for tighter curves. Guide the tool slowly, allowing the blade to follow the curve without forcing it.
• Plunge Cuts: For internal cuts without a pilot hole, tilt the jigsaw forward so the front edge of the base plate rests on the workpiece. Start the saw, then slowly lower the rear of the base plate until the blade plunges through the material. This technique requires practice and caution.

Maintenance

Regular maintenance ensures the longevity and safe operation of your jigsaw.

• Cleaning: After each use, unplug the tool and clean dust and debris from the ventilation openings and around the blade clamp area. Use a soft brush or compressed air. Do not use solvents.
• Blade Care: Inspect blades regularly for sharpness and damage. Replace dull or bent blades immediately to prevent poor cuts and potential kickback.
• Cord Inspection: Periodically check the power cord for cuts, abrasions, or damage. If damaged, have it repaired by a qualified service technician.
• Lubrication: This tool is designed for maintenance-free operation regarding lubrication. Do not attempt to lubricate internal components.
