Always disengage all power sources and allow moving parts to come to a complete stop before performing adjustments or cleaning tasks.

Warranty coverage and exclusions are detailed to define the limits of manufacturer responsibility. Typical coverage includes defects in materials and workmanship under normal operating conditions for a specified period from the date of purchase, provided the unit has been used as intended and maintained with approved parts and fluids. Consumables, wear items, and damage resulting from improper use, neglect, improper maintenance, or unauthorized modifications are commonly excluded from coverage. It is essential to retain proof of purchase and service records to substantiate warranty claims. Routine maintenance performed in accordance with the service manual, including timely oil changes, filter replacements, and lubrication, is often required to keep warranty valid. Any modifications or alterations performed without prior approval from the manufacturer can void the warranty, so consult official documentation before making changes.

Regulatory and environmental compliance encompasses adherence to applicable safety, emissions, and environmental laws. Ensure that operation complies with local noise ordinances and time-of-day restrictions to minimize community impact. Dispose of used oils, filters, and hydraulic fluids at approved facilities following environmental regulations, and never pour these fluids onto soil or water sources. The equipment should meet relevant emissions standards for combustion engines, with regular maintenance to minimize excess emissions. Follow manufacturer guidelines for proper storage of fuels and lubricants to reduce spill risks and ensure worker safety. Keep documentation on compliance readily accessible for inspections or audits and implement training for operators on regulatory responsibilities and reporting procedures.
