| Rated Voltage | 21V maximum battery voltage, normally based on a 5-cell lithium-ion battery pack with a nominal voltage of approximately 18V. | Request the battery label, cell configuration, voltage test report, and charger specification. | 8% | Not assessed |
| Maximum Cutting Capacity | Up to 40mm under the supplier’s stated wood species, moisture condition, branch hardness, and cutting mode. | Conduct a witnessed test using calibrated 40mm material and record successful cuts, blade condition, and cutting time. | 12% | Not assessed |
| Blade Material and Design | Hardened, replaceable bypass blades with consistent edge alignment and corrosion-resistant surface treatment. | Review material certificates, hardness records, blade drawings, spare-part availability, and sample cutting results. | 10% | Not assessed |
| Motor and Transmission | Brushless motor preferred; gearbox should operate without abnormal noise, excessive backlash, overheating, or oil leakage. | Request motor specifications, endurance-test records, noise data, thermal test results, and exploded assembly drawings. | 10% | Not assessed |
| Battery Safety and Capacity | Battery management system should provide overcharge, over-discharge, over-current, short-circuit, and temperature protection. Capacity must be stated in Ah and Wh. | Check battery test reports, cell traceability, protection-board specifications, cycle testing, and actual runtime under a defined workload. | 14% | Not assessed |
| Battery and Transport Compliance | Lithium battery documentation should include UN 38.3 test evidence; applicable battery safety documentation should align with IEC 62133-2 requirements. | Verify reports with the issuing laboratory and confirm that the report model, cell type, battery pack, and shipment configuration match the product. | 10% | Not assessed |
| Electrical and Environmental Compliance | Products for applicable markets should have relevant CE, EMC, RoHS, and REACH documentation, supported by valid technical files. | Check certificates, declarations, test standards, laboratory accreditation, report dates, and product-model consistency. | 10% | Not assessed |
| Safety Features | Trigger lock, accidental-start prevention, blade guard or protective cover, low-battery warning, and automatic shutdown should function correctly. | Perform a functional safety checklist during a sample inspection and review the user manual and risk assessment. | 8% | Not assessed |
| Quality Management System | Documented incoming, in-process, and final inspections; ISO 9001 certification is a useful supporting indicator but does not replace product testing. | Conduct a factory audit covering quality procedures, calibration records, nonconformance handling, and corrective-action records. | 10% | Not assessed |
| Production Capacity and Lead Time | Supplier should provide realistic monthly capacity, production lead time, raw-material risk controls, and a documented peak-season plan. | Compare declared capacity with production records, purchase-order history, staffing, equipment, and recent delivery performance. | 6% | Not assessed |
| Quality Control Plan | Inspection plan should define sampling level, critical dimensions, blade alignment, battery voltage, charger output, insulation, and functional testing. | Request the control plan, inspection checklist, sample records, calibration certificates, and pre-shipment inspection procedure. | 5% | Not assessed |
| After-Sales Support and Spare Parts | Replaceable blades, screws, chargers, batteries, switches, and control components should have defined part numbers and supply periods. | Review the spare-parts list, warranty terms, repair process, response-time commitment, and service-case records. | 5% | Not assessed |
| Overall Supplier Score | Recommended approval threshold: 80/100 or higher, with no unresolved safety, battery-compliance, or product-performance failure. | Combine document verification, factory audit, sample testing, and pre-shipment inspection before placing a large order. | 100% | Pending |
