For optimal stability and safety, it is recommended to bolt the cut-off machine to a sturdy workbench or stand. Use appropriate bolts and washers through the mounting holes provided in the base of the machine.

4.3 Installing/Changing the Abrasive Wheel

1. Ensure the machine is unplugged from the power source.
2. Press and hold the spindle lock button.
3. Using the appropriate wrench (often included), loosen and remove the arbor nut and outer flange.
4. Carefully remove the old abrasive wheel.
5. Place the new abrasive wheel onto the spindle, ensuring it is seated correctly against the inner flange. The wheel's rotation arrow should match the machine's rotation direction.
6. Replace the outer flange and arbor nut. Tighten the nut securely while holding the spindle lock button. Do not overtighten.
7. Release the spindle lock button and manually rotate the wheel to ensure it spins freely and is properly seated.

4.4 Adjusting the Fence for Miter Cuts

The adjustable fence allows for miter cuts up to 45 degrees. To adjust:

1. Loosen the fence locking bolts.
2. Pivot the fence to the desired angle, aligning it with the angle markings on the base.
3. Securely tighten the fence locking bolts.

5. Operating Instructions

5.1 Before Operation

• Ensure all safety guards are in place and functional.
• Verify the abrasive wheel is correctly installed and not damaged.
• Wear appropriate personal protective equipment (PPE): safety glasses, hearing protection, and gloves.
• Clear the work area of any obstructions and ensure adequate ventilation.
• Secure the workpiece firmly in the vise clamp. Ensure the material is stable and will not shift during cutting.

5.2 Making a Cut

1. Plug the machine into a suitable 120V AC/DC power outlet.
2. Hold the handle firmly and depress the power trigger to start the machine. Allow the abrasive wheel to reach full operating speed (3900 RPM) before beginning the cut.
