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, 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, tank and shut-off valve for wear, damage or leaks on a regular basis
and repair defects promptly.

Figure 3. Replace worn parts. Lubricate the O-rings and reassemble by

the valve stem and make sure the locking clip is positioned in the neutral
position (see “Helpful Spraying Information” section). Insert the retaining
pin. Push down on the handle a few times to distribute the lubricant
