Maintenance

NOTE TO COMMERCIAL USERS:
All mechanical equipment, no matter how well designed, will need maintenance and repairs. A NorthStar ProSHOT pressure washer is no
exception. At times, a NorthStar ProSHOT pressure washer may become inoperable because repairs are required. NorthStar ProSHOT 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: 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.
