Usage Notes

• Proper Installation: Follow installation steps strictly. Ensure washers, pilot drills, locking nuts, etc., are securely fastened to avoid inaccuracy or tool damage during operation.
• Match Speed to Material: Use low speed for hard materials (e.g., aluminum alloy) and moderate speed for soft materials (e.g., wood/plastic). Apply even pressure to prevent jamming.
• Safety Protection: Always wear safety goggles and gloves to protect against debris and improve grip.
• Correct Arbor Pairing: Use the "large arbor" for 64mm and above hole sa ws, and the "small arbor" for those below 64mm. Avoid mismatch affecting performance.
• Post-Use Care: Clean debris after use, store dry in the case to prevent rust. Regularly check tooth wear and replace if excessively worn.

Note: Slight variations in product appearance may occur due to photography angles or display settings, but this does not affect performance.
