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
fill plug/dipstick.
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.
Always perform maintenance in a wellventilated area. Gasoline fuel and fuel
vapors are extremely flammable and
can ignite under certain conditions.
! 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.
