IMPORTANT: Change oil when engine is warm from operation. Warm oil flows more
freely, carrying away more impurities. Use only recommended engine oil (see
Specifications).

2. Stop the engine and allow approximately 10 minutes for oil to drain into oil pan.
3. Remove threaded fitting from crankcase oil drain hose.
4. Install crankcase oil pump (90265A2) onto threaded fitting of oil drain hose.
