STORING / MAINTAINING YOUR SPRAYER
• The sprayer should be stored out of direct sunlight in a cool dry space.
• Before freezing weather make sure to drain all liquid in the tank, lines and pressure cylinder
to avoid liquid expansion and cracking in the sprayer components (See "Cleaning") and lock the
shut-off valve in the "open" position.
• When service is required call your nearest dealer and always insist on original manufactured
replacement parts.
• Inspect the hose, wand, pump, tank and shut-off valve for wear, damage or leaks on a regular basis
and repair defects promptly.
• Add o-ring lubricant to rod seal (located under rod entry cap) after every 40 hours of use or as needed.
