Consult the manual to determine the oil capacity and specification, such as Briggs & Stratton 300 or 10W-30, to avoid underfilling or overfilling the system. The engine should be kept level during this process, as tilting the machine can result in an inaccurate reading, potentially leading to overfilling, which causes pressure buildup and oil leaks, or underfilling, which results in inadequate lubrication.
Once drained, securely tighten the plug to the manufacturer’s specifications, being careful not to overtighten, as this can strip the threads or damage the gasket. Perform an oil change at the beginning of each cutting season to flush out the stagnant oil from storage, and then repeat the process approximately every 50 hours of operation.
