9.0 WINTER STORAGE
When the spraying season is over you should devote some extra time to
the sprayer before it is stored.
Hoses
Check that none of the hoses are caught or have sharp bends.
A leaky hose can give an annoying delay in the middle of the spraying
job. Therefore check all the hoses and change if there is any doubt about
the durability.
Paint
Some chemicals are very hard on paints. It is therefore recommended to
remove rust, if any, and then touch up the paint.
Tank
Check that no chemical residues are left from the last spray job. Chemi-
cal residues must not be left in the tank for a long time. This will reduce
the life of the tank. See section on cleaning the sprayer.
ESC Controls
When storing the sprayer, the control box and the multiplug must be
protected against moisture and dirt. A plastic bag can be used around the
plug.
P.T.O. shaft
It is important that the push pins are clean and well lubricated, to ensure
safe function.Every 40 hours: Inspection of protection guards, function
and condition. Replace possible damaged parts.Every 1000 hours:
Check condition of protection guards and replace nylon bearings.
Check general condition of cross journals and push-pin/quick release -
replace if necesary.
Anti-freeze precaution
If the sprayer is not stored in a frost free place you should take the follow-
ing precautions: Drain as much water as possible from sprayer. Pour in a
mixture of ethylene glycol base anti-freeze and water at the ratio for the
desired temperature protection. (Volume of mixture should be about 1%
of tank volume) Run the sprayer and circulate the anti-freeze in to the
pump, controls and boom lines.
NOTE: NEVER USE OIL OR DIESEL FUEL IN A SPRAYER
The anti-freeze solution also prevents the O-rings and gaskets from
drying out.
Remove the glycerine filled pressure gauge and store it in a frost free and
vertical position.
Remove nozzles & screens. Clean and store in a safe, dry location.
Turn pressure regulator valve counter-clockwise until all spring tension is
released. Turn boom section valves off.
Store sprayer in a safe, dry location away from children and animals.
Protect from direct sunlight.
