Oil is a major factor in the performance and service life of any engine. Using the incorrect
oil may damage the engine and void the warranty. To avoid causing engine damage and
voiding the warranty, check and change oil as required using the correct engine oil.
1. Check oil with pressure washer on a level surface and the engine off.

3. Place clean dipstick into filler neck but do not thread it in, leave it rest it on the filler neck.
4. Remove the dipstick from filler neck and check oil level. Oil level should be at the upper oil
limit on the dipstick.

limit on the dipstick. See the engine manual for recommended oil.
