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, pump, pressure cylinder, hose,
shut-off valve, wand and nozzle, to avoid liquid expansion and cracking in the sprayer components
(See "Cleaning" section). 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.
• Every year prior to spraying remove felt gasket (see Pump Disassembly and Rebuild) and saturate
with a light oil. Oil periodically thru out the season as needed.
