Maintenance
Regular maintenance is crucial for the performance and longevity of your Briggs & Stratton engine. Always refer to the full owner's manual for detailed maintenance schedules and procedures.
Oil Changes
Check the oil level before each use. Change the engine oil after the first 5 hours of operation, then every 50 hours or annually, whichever comes first. Use the recommended oil type and viscosity.
Air Filter
Inspect the air filter every 25 hours or annually. Clean or replace the air filter more frequently in dusty conditions. A dirty air filter can reduce engine performance and life.
Spark Plug
Inspect the spark plug annually or every 100 hours. Clean or replace if necessary. Ensure the gap is set correctly according to specifications.
Storage
For long-term storage (over 30 days), add a fuel stabilizer to the gasoline or drain the fuel system completely. Clean the engine exterior, change the oil, and remove the spark plug to add a small amount of oil into the cylinder before reinstalling.
