Operating Instructions

Familiarize yourself with the controls and adjustments before making any cuts.

Basic Operation

• Power On/Off: Locate the main power switch. Always ensure the blade is clear before starting.
• Workpiece Placement: Place the workpiece firmly against the fence. Use clamps for added stability, especially for long or wide pieces.
• Cutting: With the motor running at full speed, slowly pull the saw carriage through the workpiece. Maintain a steady, controlled feed rate.
• Return: After the cut, allow the blade to stop spinning before returning the carriage to its resting position.

Adjustments

• Crosscut Angle (Miter): Loosen the miter lock knob, adjust the arm to the desired angle (e.g., 90° for straight cuts, 45° for miter cuts), and re-tighten the knob.
• Bevel Angle: Loosen the bevel lock, tilt the motor assembly to the desired angle, and re-tighten.
• Depth of Cut: Adjust the height of the radial arm or the motor assembly to set the desired cutting depth.
• Rip Cuts: For ripping, rotate the motor assembly 90 degrees and adjust the fence as needed. Exercise extreme caution during rip cuts.

Maintenance

Regular maintenance ensures the longevity and safe operation of your radial arm saw. Always disconnect power before performing any maintenance.

• Cleaning: Regularly clean sawdust and debris from the saw, especially around the motor, blade guards, and arm tracks. Use compressed air or a brush.
• Lubrication: Apply a light coat of machine oil to the radial arm tracks and other moving parts as indicated in the diagrams. Do not over-lubricate.
• Blade Inspection: Inspect the saw blade for sharpness, damage, or missing teeth before each use. Replace dull or damaged blades immediately.
• Belt Tension: Check the motor belt tension periodically. Adjust or replace if necessary.
