Maintenance Instructions
WARNING: Unauthorized machine modification or use of non-approved replacement parts may cause personal
injury and/or property damage and will void the manufacturer warranty.
All mechanical equipment, no matter how well designed, will need repairs. A North Star pressure washer is no exception.
At times, a North Star pressure washer may be inoperable because repairs are required. North Star Customer Service
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:
1. Have someone on staff who is trained in the operation of the pressure washer and is capable of making minor repairs
and performing all preventative maintenance procedures as outlined in the provided manuals.
2. Keep a stock of recommended service parts for maintenance and minor repairs.

washer, it must be placed in maintenance mode.
