NOTE TO COMMERCIAL USERS:
All mechanical equipment, no matter how well designed,
will need maintenance and repairs. A NorthStar
pressure washer is no exception. At times, a NorthStar
pressure washer may become inoperable because
repairs are required. NorthStar Product Support will
assist in these repairs as needed, but if an inoperable
pressure washer creates a major expense to your
business, then we strongly recommend the following:
Have a staff person become familiar with the

mechanical operation of the pressure washer and
capable of making minor repairs and performing all
preventative maintenance procedures.
Keep a stock of recommended service parts for

maintenance and minor repairs.
IMPORTANT: Replacement Parts
If a part needs replacement, only use parts that meet
the manufacturer's part number specifications.
Replacement parts that do not meet specifications may
result in a safety hazard or poor operation of the
pressure washer
