Routine Maintenance vs Warranty Claims

Our drill machine handpieces are precision tools designed for professional use. Like any mechanical device, they require regular maintenance to function reliably over time. Natural wear is expected and is not considered a manufacturing defect.

Important:

• Routine maintenance such as cleaning, lubrication, and replacement of wear parts (e.g., bearings, shafts, collets) is not covered under warranty.
• Warranty covers only manufacturing defects under normal, proper use.

Reminder:
Cleaning and maintenance instructions are provided in the machine's user manual. Customers are expected to follow these guidelines to preserve product performance.

Initial Warm-Up Period for New Handpieces

All new handpieces have a warm-up period during initial use.
For the first 2 weeks, it is normal to experience:

• Slight noise
• Minor vibration
• Irregular behavior during rotation

These symptoms should subside within 3 hours of total (non-continuous) use.

If issues persist beyond this, please contact us for further evaluation.

Warranty claims will not be accepted for noise or vibration reported during the warm-up period.

Preventing Dust Damage – Use of Protection Bur

It is very important to install the protection bur (included with your handpiece) or any drill bit when the handpiece is not in use.

This prevents dust, debris, and moisture from entering the chuck and causing internal damage.

Failure to use a protection bur may lead to early wear, improper function, and can void warranty eligibility.

Flat-Fee Maintenance Service – $50

If your handpiece requires service and is not eligible for warranty, we offer a flat-rate $50 maintenance service, which includes:

• Prepaid shipping label to send the handpiece to our service center
• Full diagnostic inspection
• Internal cleaning, lubrication, and minor repairs
• Return shipping back to you

This service also applies if a warranty claim is submitted, but the issue is diagnosed as routine wear or dust-related damage.

Shipping Policy (After 30 Days)

For all claims after 30 days from purchase, the customer is responsible for:

• Shipping costs related to both warranty and paid service
• Proper packaging and protection to avoid transit damage

Our flat $50 service includes round-trip shipping if you use our label. You may also choose to use your own label, but the service cost remains unchanged.

Packaging & Shipping Requirements

Before shipping:

• Do NOT ship dirty products, please wipe them out from nail dust before shipping 
• Insert a protection bur or drill bit in the chuck
• Pack the handpiece securely using protective materials (foam, bubble wrap)
• Use a sturdy box to avoid damage

Units arriving without proper cleaning or protection may be delayed or rejected.
