Adhere to occupational safety guidelines and environmental regulations when draining fluids or disposing of used parts, and ensure that service work is conducted by qualified personnel. Regularly review manufacturer advisories and regulatory updates to stay current with changes that could affect maintenance procedures or permissible equipment configurations. Environmental disposal guidelines Proper disposal of spent fluids, filters, batteries, and worn components is critical to minimize environmental impact. Contain and label used engine oil, fuel, hydraulic fluid, and coolant in appropriate containers and transport them to an approved recycling or disposal facility. Do not pour hazardous liquids onto the ground or down drains; containment and proper disposal are required by environmental regulations. For filters and parts that contain contaminants, follow local guidelines for hazardous waste handling and consider returning used parts to the manufacturer or an authorized service center if a take-back program is available. When disposing of batteries, observe rechargeable battery handling standards and ensure terminals are protected to prevent short circuits. Maintain a log of disposal activities, including date, contents, and destination facility, to support compliance audits and environmental stewardship obligations.
