Place a shallow pan or tarp beneath the oil drain plug to contain the used fluid, remembering that even a single quart of old oil can contaminate significant amounts of groundwater. Start the engine and let it run for a full minute, then turn it off and wait a few moments for the oil to return to the sump.
Craftsman Lawn Mower Oil Change Safety Steps
Viewing an oil change not as a chore, but as a necessary investment in reliability, ensures your equipment remains ready for every cutting season. Disconnect the spark plug wire and remove the key to eliminate the possibility of accidental starting during maintenance.
Always wear protective gloves to shield your hands from hot metal and harsh detergents, and keep rags nearby to catch drips, but never use them while your hands are greasy to avoid slipping. Allow the oil to drain completely until the flow slows to a drip, which indicates that residual oil clinging to the oil passages has been expelled.
Safety Steps Before Starting an Oil Change
Fresh oil circulates heat away from critical components, suspends contaminants, and prevents the internal corrosion that occurs when the machine sits idle for months. Once drained, securely tighten the plug to the manufacturer's specified torque, being cautious not to overtighten the soft aluminum housing found on many craftsman models.
