“ If using water-base paints :
• Remove spray tip and guard . Wash these by hand .
• Flush the system thoroughly with water . Warm water can help speed this process .
• Pull gun filters after initial flush ( maybe after 1-2 gallons ) and continue to flush without filters until water is mostly clear ( 5 gallons or so ). Wash filters by hand . Replace filters .
• Finally , flush with Pump Armor or similar storage fluid to prevent damage from corrosion or freezing .
• Replace spray tip and guard ( this way you won ’ t lose them ).
• DO NOT leave water in the pump . Water is corrosive and will cause rust . Also , water can freeze and damage the pump and other components .

Vangstad also offered winterizing suggestions for the line striper systems engine .
“ My best advice is to follow the engine manufacturer ’ s recommendations ,” Vangstad said . “ I would also advise adding a stabilizer to your gas . Make sure to run the engine for a minute to ensure that the gas with stabilizer makes its way into the engine . Shut the fuel valve on the engine while it is running and leave running until the engine stops . This will evacuate the fuel from the carburetor and stop additional fuel from entering while moving the equipment ( and flooding the carburetor ).”
With the season ending and winter ’ s faster than expected approach , it is advised by the experts that contractors invest the time and effort in winterizing their equipment investment .
