Safety Instructions

Always follow basic safety precautions to reduce the risk of fire, electric shock, and personal injury. Keep work area clean and well lit. Do not operate power tools in explosive atmospheres, such as in the presence of flammable liquids, gases or dust. Power tools create sparks which may ignite the dust or fumes.

When operating a power tool outdoors, use an extension cord suitable for outdoor use. Use of a cord suitable for outdoor use reduces the risk of electric shock.

Always wear appropriate personal protective equipment, including safety glasses, hearing protection, and gloves.

Blade Installation:

Power Connection:

Connect the saw's power cord to a standard 120V AC outlet. Ensure the outlet is properly grounded.

Operating

Starting and Stopping:

• To stop the saw, release the trigger switch.
• For continuous operation, depress the trigger switch and then push in the lock-on button. To release, depress the trigger switch fully, then release it.

Adjusting the Shoe:

The shoe can be adjusted to control the depth of cut and to utilize different sections of the blade, extending blade life. To adjust, loosen the shoe adjustment knob, slide the shoe to the desired position, and tighten the knob securely.

Cutting Techniques:

• Always ensure the workpiece is securely clamped.
• Place the shoe firmly against the workpiece before starting the cut.
• Allow the saw to reach full speed before engaging the material.
• Apply steady, even pressure. Do not force the saw through the material.
• For plunge cutting, ensure the blade is sharp and the material is suitable.

Maintenance

Regular maintenance ensures optimal performance and extends the life of your tool. Always unplug the saw before performing any maintenance.

Cleaning:

Periodically clean the saw's ventilation openings to prevent overheating. Use a soft cloth to wipe down the exterior. Do not use harsh chemicals or abrasive cleaners.

Blade Care:

Inspect blades before each use for sharpness and damage. Replace dull or damaged blades immediately. Store blades in a dry place to prevent rust.

Cord Inspection:

Regularly check the power cord for cuts, abrasions, or signs of wear. If damaged, have it repaired by a qualified service technician.
