5. Operating Instructions

This section details the operation of your PYY Lapidary Saw for various tasks.

5.1. Powering On and Speed Control

• Plug the saw into a standard 110V power outlet.
• Turn the power switch to the "ON" position.
• Use the front dial to adjust the motor speed from 0 to 10,000 RPM. Start at a lower speed and gradually increase as needed for the material being worked on.

5.2. Cutting Operations

• Select the appropriate blade for your material (woodworking blade for wood/plastic, diamond blade for stone/metal).
• For wet cutting (stone, jade), ensure the water pump and cooling pipe are set up and providing a steady stream of water to the blade.
• Position the material against the pusher angle ruler for accurate cuts.
• Slowly and steadily feed the material into the rotating blade. Do not force the material, as this can cause kickback or damage the blade/motor.
• Maintain a firm grip on the material and keep hands away from the blade.
• The maximum cutting thickness for stone is 35mm.
