Echo MS-40BD manual Storing / Maintaining Your Sprayer, Trouble Shooting Your Sprayer

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.
