2. Installing the Wheel Guard

The wheel guard is essential for safety and must always be in place during operation.

1. Loosen the wheel guard clamp screw or lever.
2. Position the wheel guard over the spindle housing, ensuring it covers the top portion of the disc and directs sparks away from you.
3. Tighten the clamp screw or lever securely.

3. Installing/Changing Grinding or Cutting Wheels

Always ensure the tool is unplugged before changing accessories.

1. Depress the spindle lock button and hold it.
2. Using the supplied wrench, loosen the lock nut by turning it counter-clockwise. Remove the lock nut and the outer flange.
3. Place the desired grinding or cutting wheel onto the inner flange, ensuring it sits flush.
4. Replace the outer flange and the lock nut.
5. Depress the spindle lock button again and tighten the lock nut securely with the wrench by turning it clockwise. Do not overtighten.
6. Release the spindle lock button and ensure the wheel is firmly seated and rotates freely.

Operating Instructions

1. Powering On/Off

• To turn on: Slide the ON/OFF switch forward until it clicks into the ON position.
• For continuous operation: Push the switch further forward and press down on the front part of the switch to engage the lock-on function.
• To turn off: If locked on, press the rear part of the switch to release the lock, then slide the switch back to the OFF position. If not locked on, simply slide the switch back to the OFF position.

2. General Operation Tips

• Allow the grinder to reach full speed before contacting the workpiece.
• Apply light, even pressure. Do not press too hard, as this can reduce efficiency and damage the disc or motor.
• Maintain a firm grip on both the main handle and the auxiliary handle.
• Always work with the wheel guard positioned to protect you from sparks and debris.
• For cutting, use a cutting disc and make shallow passes. For grinding, use a grinding disc and maintain a slight angle to the workpiece.
