When mosquito season winds down, your ULV spray equipment deserves the same care it’s given your community all season. Whether you’re running our gas-powered Grizzly and Cougar or our electric Pro-Mist, proper winterization ensures reliable performance year after year, protects your investment, and guarantees you’re ready when next season arrives.
ULV sprayers work hard during mosquito season, often operating in challenging conditions, handling insecticides, and running thousands of miles. Without proper pre- and post-season care, you risk equipment failure, costly repairs, and operational downtime. The good news? A systematic maintenance approach can reduce these issues before they start and prolong the life of equipment.
Your insecticide and flush tanks require thorough cleaning at season’s end. Residual chemicals and oils can degrade components over time, leading to clogs, corrosion, and system failures. A complete flush-and-drain process removes these harmful residues and prepares your system for storage.
Fuel left in the tank can degrade and damage internal components. Oil can break down and fail to protect critical engine parts. Taking the time to properly drain fuel, replace oil, and protect cylinder walls with a light coating of engine oil makes the difference between a smooth spring startup and a costly repair bill.
The blower assembly is particularly vulnerable during storage. Without proper preparation, internal components can rust and seize, rendering your equipment useless. Applying lightweight penetration lubricant and following proper storage procedures keeps your blower ready for action.
Clean filters and housings to ensure optimal airflow and system performance. Inspecting and cleaning these components prevents blockages that reduce spray effectiveness and strain your equipment.
Different equipment models have unique maintenance requirements. The Pro-Mist Dura, for example, needs special attention to UV degradation and residual build-up. Its sleeve assembly requires specific flushing procedures and regular inspection to avoid damage to the spray head. Understanding your equipment’s specific needs is essential for proper care.
Each spring, Clarke’s control consultants offer free workshops and equipment rodeos for our customers covering these maintenance steps and pre-season calibrations—because we’re here to help you succeed.
We’ve also created a comprehensive checklist that walks you through every step of pre- and post-season maintenance for your Clarke ULV spray equipment. From the Grizzly ULV Sprayer to the Pro-Mist Dura, this detailed guide covers everything you need to know to keep your equipment in peak condition.
