Installing diamond slitting discs

1. Lay the tool on its left side with the spirit level facing up.
2. Press and hold the carriage release button to unlock the carriage and swing it out.
3. Fit the clamping flange onto the spindle.
4. Place the first diamond slitting disc on the flange, ensuring the rotation arrow matches the tool's direction.
5. Select and place the correct spacer rings for the desired slit width.
6. Place the second diamond slitting disc.
7. Warning: Always install all remaining spacer rings on the clamping flange after the second disc to prevent the wheels from working loose.
8. Screw on the clamping nut and tighten with the pin wrench while holding the spindle lock button.
9. Pivot the carriage back until it engages.

Operation

Setting initial position: Ensure the plunge movement lock button is not pressed. Lift the front of the tool until the carriage snaps into the initial position with an audible click.

Setting slitting depth: With the tool in the initial position, turn the slitting-depth adjusting knob to the desired depth in millimeters.

Slitting: Position the tool on the surface. Flick the locking lever, depress the ON/OFF switch, and hold the plunge movement lock button. Wait for the discs to reach full speed before plunging into the material. Guide the tool with both hands using reasonable pressure.

Care and maintenance

Always unplug the tool before maintenance. Clean air vents with a dry brush. The service indicator will light up when carbon brushes need replacement. Always replace all carbon brushes at the same time. After replacement, run the tool under no load for at least 1 minute to ensure proper seating.

Troubleshooting

If the service indicator flashes or shows red, the motor may be overheated or the carbon brushes may be worn. If the tool does not start, check the power supply, cord, or switch. If cutting performance is low, check if the diamond discs are worn or unsuitable for the material.
