Harden Auto-Oil Glass Cutter - 175mm

Use a specialized glass cutting oil. This type of oil is designed to lubricate the cutting wheel and help create a cleaner score line.

The frequency of refilling depends on how often you use the cutter. Monitor the oil level and refill when it appears low to ensure consistent lubrication.

No, this glass cutter is not designed for tempered glass. Tempered glass is much harder and requires specialized tools for cutting.

For straight cuts, use a ruler or a straight edge guide clamped to the glass. Score along the edge of the guide with consistent pressure.

The lifespan of the YG8 Tungsten Carbide cutting wheel depends on usage and care. With proper lubrication and avoiding excessive force, it can last for a significant number of cuts. If scoring becomes difficult, the wheel may need replacement.

Store the glass cutter in a clean, dry place. It's best to keep the cutting head protected to prevent damage and maintain its sharpness.

Ensure the oil reservoir is filled and the oil is reaching the cutting wheel. Check if the cutting wheel is worn or damaged; replace if necessary. Apply consistent, even pressure during scoring.

Verify that the cutting wheel is clean and sharp. Ensure you are scoring in one continuous motion. Use a straight edge or guide for precise lines and support the glass properly during the break.

Check that the reservoir cap is screwed on tightly and that the reservoir itself is not cracked. If the cap or reservoir is damaged, contact the manufacturer for a replacement.

Ensure the oil reservoir is adequately filled, as the oil lubricates the wheel's rotation. Clean any debris around the wheel mechanism.
