Last Updated: December 1, 2025
This Warranty & Repairs page explains how Dunfer, a brand of Cobra Stone Inc. (“Dunfer,” “we,” “us,” or “our”), supports warranty coverage and repair assistance for products purchased through our online store.
By placing an order on our website, you agree to the practices described here, in addition to our Terms & Conditions, Safety & Installation Disclaimer, Returns & Refunds, and Shipping & Delivery pages.
1. General Overview
Dunfer is primarily a reseller and distributor of vehicle lifts, garage equipment, and related products. In many cases, warranty coverage is provided directly by the original manufacturer of the product.
- Manufacturer warranties, where offered, are governed by the manufacturer’s terms, conditions, and procedures.
- Dunfer may assist you with information and documentation but does not alter or extend the manufacturer’s written warranty.
- Some items may have limited or no warranty; details will generally be stated in the product documentation or on the product page.
2. Types of Warranty Coverage
Warranty coverage for products purchased from Dunfer may include one or more of the following, depending on the item and manufacturer:
- Manufacturer’s Limited Warranty: Coverage provided by the original manufacturer for defects in materials or workmanship under normal use and proper installation.
- Component or Parts Warranties: Certain components (such as power units, cylinders, or structural elements) may have specific warranty periods defined by the manufacturer.
- No-Warranty or “As-Is” Items: Some products, clearance items, or specially marked products may have limited or no warranty coverage and will be sold as described at the time of purchase.
Always review the documentation that arrives with your product and any warranty information posted on the product page.
3. Warranty Eligibility
To qualify for warranty consideration, products typically must:
- Be purchased from Dunfer or an authorized reseller;
- Be used only for their intended purpose and within their rated capacity;
- Be installed, operated, and maintained according to the manufacturer’s instructions and safety guidelines;
- Not be modified, misused, abused, or subjected to accidental or intentional damage; and
- Be within the applicable warranty period at the time a claim is made.
Manufacturer and product-specific terms always control eligibility. Dunfer cannot guarantee approval of any claim that does not meet the manufacturer’s requirements.
4. What Is Typically Not Covered
Warranty coverage usually applies only to defects in materials and workmanship under normal conditions. It often does not cover:
- Improper installation, anchoring, wiring, or site preparation;
- Damage caused by misuse, abuse, overloading, or operation outside the intended use;
- Normal wear and tear, including pads, cables, hoses, seals, and other consumable parts;
- Damage from accidents, environmental conditions, corrosion from harsh chemicals, or natural disasters;
- Damage resulting from unauthorized repairs, modifications, or non-approved parts and accessories;
- Cosmetic defects that do not affect the safe functioning of the product.
Refer to the specific manufacturer’s warranty for a full list of exclusions and limitations.
5. Warranty Registration
Some manufacturers require warranty registration to activate or extend coverage.
- Registration may involve submitting your serial number, installation date, and contact information directly to the manufacturer.
- Failure to register when required may limit or void certain warranty benefits, depending on the manufacturer’s policy.
- Keep a copy of your order confirmation, installation records, and any registration acknowledgments for your records.
6. How to Submit a Warranty Claim
If you believe your product may qualify for warranty service, please follow these steps:
- Locate your proof of purchase (order number, invoice, or receipt from Dunfer).
- Gather details about the product, including model, serial number (if applicable), and description of the issue.
- Take clear photos or videos showing the problem, any damage, and the installation area, if relevant.
- Contact us with this information so we can help direct you to the appropriate warranty process, which may involve the manufacturer.
Depending on the product and warranty terms, we may connect you directly with the manufacturer or help coordinate communication on your behalf.
7. Evaluation & Approval
Warranty claims must be evaluated and approved in accordance with the applicable warranty terms.
- The manufacturer or authorized service provider will typically determine whether the issue is covered under warranty.
- You may be asked to provide additional information, photos, maintenance records, or inspection reports.
- In some cases, physical inspection of the product by a qualified technician or return of the defective component may be required.
Dunfer does not control the outcome of manufacturer warranty evaluations and cannot guarantee approval of any claim.
8. Warranty Remedies (Repair, Replacement, Parts)
If a warranty claim is approved, remedies generally follow the manufacturer’s policy and may include:
- Repair: Repair of the defective product or component, either on-site or at an authorized service location.
- Replacement Parts: Supply of replacement components or parts for installation by a qualified technician.
- Product Replacement: Replacement of the product with the same or similar model, at the manufacturer’s discretion.
Refunds are generally not a standard warranty remedy and are typically handled separately under our Returns & Refunds policy if applicable.
9. Warranty-Related Shipping & Labor Costs
Warranty coverage typically applies to the product or parts and may not include all associated costs.
- Shipping costs for warranty parts or returns may or may not be covered, depending on the manufacturer’s policy.
- Labor for removal, installation, diagnosis, or travel by technicians is often not covered under parts warranties and may be your responsibility.
- For freight-sized components or equipment, you may be responsible for coordinating and paying for removal, packing, and shipping if required.
Please review the specific warranty documentation to understand what costs are covered and what costs may fall to you.
10. Repairs Outside of Warranty
If your product is outside its warranty period or the issue is not covered by warranty:
- We may be able to provide replacement parts for purchase, subject to availability and manufacturer support.
- We can often help you identify compatible parts or connect you with manufacturer resources or service networks.
- You are responsible for all parts, labor, shipping, and related costs for non-warranty repairs.
All repair work should be performed by qualified, trained professionals who are familiar with the specific equipment and safety requirements.
11. Authorized Service & Installers
For safety and warranty reasons, some manufacturers require installation and repair work to be performed or supervised by authorized or certified technicians.
- Dunfer does not supervise or control third-party installers, service centers, or technicians and is not responsible for their workmanship, methods, or compliance with codes and regulations.
- Using non-authorized service providers where a manufacturer requires authorization may limit or void warranty coverage.
- Always verify the credentials, experience, and insurance of any installer or service provider you choose.
12. Relationship to Safety & Installation Requirements
Proper installation and safe operation are critical for both safety and warranty coverage.
- Warranty coverage may be denied if damage or failure is linked to improper installation, incorrect anchoring, inadequate concrete, electrical issues, overloading, or failure to follow the manufacturer’s instructions.
- Always review and follow the Safety & Installation Disclaimer and the product’s manuals before installation and use.
Failure to meet safety and installation requirements may create serious hazards and may also affect the availability of warranty remedies.
13. Limitations of Warranty & Liability
All warranties are subject to the limitations, exclusions, and conditions stated in the manufacturer’s documentation and our Terms & Conditions.
- Dunfer does not provide additional warranties beyond those required by law or expressly stated in writing.
- We are not liable for incidental, consequential, or special damages resulting from product failure, downtime, or loss of use, to the extent permitted by law.
- Some states may not allow limitations on implied warranties or exclusion of certain damages; in those cases, some of the above limitations may not apply to you.
14. Documentation & Recordkeeping
To help protect your warranty rights, we recommend that you keep the following:
- Order confirmation, invoice, or proof of purchase from Dunfer;
- Installation records, including installer information and dates;
- Maintenance logs, including inspections, adjustments, and repairs; and
- Any correspondence or claim numbers related to warranty inquiries.
Accurate documentation can streamline the warranty process and support your claim with the manufacturer.
15. Changes to This Warranty & Repairs Policy
We may update or revise this Warranty & Repairs page from time to time to reflect changes in products, manufacturer programs, or legal requirements.
- Updates will be noted by the “Last Updated” date at the top of this page.
- The version in effect at the time of your purchase will generally apply to that order, unless changes are required by law or a manufacturer’s updated warranty.
16. Questions & Contact Information
