Paint
Some chemicals are very hard on paints. It is therefore well advised to
remove rust, if any, and then touch up the paint.
Tank
Check that no chemical residues are left from the last spraying. Chemi-
cal residues must not be left in the tank for a long time. It will reduce
the life of the tank. See Spray Technique book- Cleaning the sprayer.
Operating unit
Take care that the pressure regulation valve is
completely loosened. The spring is thereby
relieved and operation difficulties are avoided at
starting-up next season.
Anti-freeze precaution
If the sprayer is not stored in a frost-proof place you should take the
following precautions: Put at least 5 litres of 33% anti-freeze mixture in
the tank and let the pump run a few minutes so that the entire system
including spray hose are filled. Remove the glycerine filled pressure
gauge and store it frost free in vertical position.
The anti-freeze solution also hinders the O-rings and gaskets from
drying out.
