MAINTENANCE
Before performing maintenance on the pressure washer, review Safety on page 7 and the following safety messages.
!
WARNING
Avoid accidentally starting the
!
pressure washer during maintenance by removing the spark plug boot from the spark plug.
Allow hot components to cool to the touch prior to performing any maintenance procedure.
Internal pressure can build in the engine crankcase while the engine is running. Removing the oil fi ll plug/ dipstick while the engine is hot can cause extremely hot oil to spray out of the crankcase and can severely burn skin. Allow engine oil to cool for several minutes before removing the oil fi ll plug/dipstick.
Always perform maintenance in a well­ventilated area. Gasoline fuel and fuel vapors are extremely fl ammable and can ignite under certain conditions.
Maintenance Schedule
!
WARNING
Failure to perform periodic
!
maintenance or not following maintenance procedures can cause the pressure washer to malfunction and could result in death or serious injury.
NOTICE
Periodic maintenance intervals vary depending on pressure washer operating conditions. Operating the pressure washer under severe conditions, such as sustained high-load, high-temperature, or unusually wet or dusty environments, will require more frequent periodic maintenance. The intervals listed in the maintenance schedule should be treated only as a general guideline.
Following the maintenance schedule is important to keep the pressure washer in good operating condition. The following is a summary of maintenance items by periodic maintenance intervals.
!
CAUTION
Avoid skin contact with engine oil or gasoline. Prolonged skin contact with engine oil or gasoline can be harmful. Frequent and prolonged contact with engine oil may cause skin cancer. Take protective measures and wear protective clothing and equipment. Wash all exposed skin with soap and water.
