New and Repaired Cylinders: Covered by a warranty period of 12 months from date of delivery or 3000 hours of operation, whichever occurs first.

1.2). Drivetrain Components

Repairs on Drivetrain Components: Covered by a warranty period of 6 months from date of delivery or 1000 hours of operation, whichever occurs first.

1.3). Hydraulic Drifters (Rock Drills)

Warranty Period: Covered by a warranty period of 2 – 4 months from date of delivery or 200 – 400 hours (make and model specific warranty periods) of operation, whichever occurs first.

2). Warranty Terms and Conditions

2.1). Standard Warranty Terms and Conditions

HERS guarantees that our warranty policy will, at a minimum, align with the warranty terms and conditions provided by the OEM manufacturer or supplier. We also guarantee that any items manufactured, supplied, installed and delivered by HERS, will be free from defects in material and workmanship for the duration as specified under the Warranty Coverage section.

Additionally, if a warranty claim is accepted by HERS, we will provide the replacement part/s and labour necessary to repair and refurbish failed component/s at no charge to the customer based on the condition that the work is executed at our premises and by our personnel.
Please note that parts not included in the original Scope of Work (SOW) or approved quotation will not be covered under this warranty. The cost of investigating any failures will be covered by HERS, unless the fault is found to be due to factors beyond our control and if the customer insists on third party involvement, in which case the investigation costs will be charged to the customer or their end customer.

Our warranty excludes coverage for issues resulting from negligence, improper installation or operating practices, damage emanating from the underground environment and maintenance deficits or operating conditions or exposure as outlined by the OEM and the product’s technical manual. Any evidence of tampering will void the warranty.

2.2). Warranty Segments

  • Without Supporting Documentation: The warranty period will be based on circulation time only, as specified above.
  • With Supporting Documentation: If the customer provides verified supporting documentation from their Planned Maintenance Document (PMD) indicating the commissioning and decommissioning dates, operational hours and maintenance records, the warranty period will be extended to both period and time-based conditions. The extended warranty will be for the specified periods (months) or the total documented operational hours (whichever occurs first) from the date of commissioning, with a maximum allowable period of 12 months.

2.3). Exclusions and Limitations

  • Workmanship and Material Only: The warranty covers only workmanship and material defects. No additional claims will be honoured for downtime, injury, or consequential damages that may occur.
  • Contamination: Should the Root Cause Failure be attributed to contamination in the systems or circuits into which our components are installed, the warranty claim will not be entertained. It is the responsibility of the customer to ensure that systems are free from contaminants before installation.
  • Attachments: Any loose or bolt on attachments that accompany the components, such as fittings, pipes, valve blocks, brackets, plugs, etc., and which did not form part of the refurbishment SOW will be excluded from any warranty conditions.
  • OEM Spare Parts: If an OEM spare part is unavailable or cannot be sourced timely, it is the prerogative of the customer to decide whether they will supply the parts, spares or component or issue a directive to HERS authorising the use of an alternative parts, spares or component which conform to the required standards and norms.
  • Repair Specifications: Cylinders or General Engineering Repairs will be affected based on the sample sent by the customer or an approved drawing. In the absence of a customer approved drawing, repairs or manufacturing will follow engineering best practice and general engineering principles and specifications.
  • Scope of Warranty: The warranty covers all work carried out as per our SOW, quotation and customer purchase order. Latent faults due to hydraulic components or electrical interfaces not included in our scope of supply are excluded from the warranty.
  • Testing Parameters: Unless otherwise specified by the customer, test pressures and testing parameters will follow OEM specifications or, in their absence of documented guidelines, standard hydraulic practice specifications as well as industry standards and norms.

2.4). Additional Conditions

  • Third-Party Work Management: As an additional service, HERS may manage and control work carried out by third parties, if so instructed by the Customer. In such cases, a buyout item will carry the original manufacturer or repairer’s warranty. HERS will be excluded from any dispute arising from a warranty claim except for managing the process.
  • Oil Specifications:
    • Cylinders must be operated with specified hydraulic oil as determined by the relevant OEM or Site-Specific requirements.
    • Drivetrain products must be filled as per OEM specifications with the correct grade of oil, complying with API-GL5 where relevant.
    • Externally cooled brakes must be filled with oil conforming to OEM specifications, which often require limited-slip (LS) additives. Brake warranties are voided if the correct oil is not used.
  • Storage Requirements:
    • Drivetrain Components: Must be stored in a conducive environment, with all ports sealed. Components should be palletised or caged and stored in their operating orientation, with breathers facing either upwards or parallel to the ground to prevent oil leakage. The storage methodology and usage of the component which is being deployed by the client must ensure that components are issued on a “First in First Out” bases to ensure the required circulation of components.
    • Hydraulic Cylinders: Must be stored vertically (to protect against seal deformation) in a clean environment with all ports sealed. The storage methodology and usage of the component which is being deployed by the client must ensure that components are issued on a “First in First Out” bases to ensure the required circulation of components.
    • Hydraulic Rock Drills: Must be stored in a clean environment, with all hydraulic ports and other ports correctly plugged. Hydraulic components should not be stored in an environment which is high in humidity for extended periods of time. The storage methodology and usage of the component which is being deployed by the client must ensure that components are issued on a “First in First Out” bases to ensure the required circulation of components.

2.5). Warranty Voidance

All warranties shall become null and void:

  • If the component or a segment thereof was not decommissioned in strict accordance to the required industry standard and norms, OEM specifications or requirements as specified above.
  • If any evidence is obtained indicating that the component was tampered with during the applicable warranty period or following the decommissioning of the component.
  • Any of the specified conditions are not adhered to.
