GUIDE
The Curtis Snowplow family of products are built and tested for lasting performance. All snowplows are fully tested for
electrical, hydraulic and lighting malfunctions prior to shipping. Any malfunction is corrected immediately at our facility to ensure that
our customers receive a quality product that will last for years to come. As with any piece of equipment, rough service and harsh
environments can lead to poor performance, necessitating repairs.
When diagnosing snowplow malfunctions, it is important to methodically separate and test the different systems that are
utilized on the Curtis Sno-Pro series snowplows. The approach detailed below will greatly reduce diagnostic time and take the guess
work out of troubleshooting. What this means is lower associated labor, fewer unnecessary parts and more satisfied customers.
The following pages contain the hydraulic circuit as well as the electrical system. Each diagram shows a specific function, and what
actually happens when a function is activated. The information will be useful in helping to understand what to look for when
troubleshooting a snowplow malfunction. Each page, both electrical and hydraulic, has a "What Happens" heading at the top of the
page. This will offer a step by step sequence of what takes place internally in the snowplow system once the controller is activated.
This will act as a guide to what to look for as a possible cause of a malfunction.
