Off-Season Storage
General Info
To preserve the sprayer intact and to protect its components, carry out following off-season storage program.
Before Storage
When the spraying season is over, you should devote some extra time to the sprayer. If chemical residues are left over in the
sprayer for longer periods, it may reduce the life of its individual components.
1. Clean the sprayer completely both inside and outside as described under "Cleaning" on page 126. Make sure there is
no chemical residues left in the sprayer by cleaning all valves, hoses and auxiliary equipment with a cleaning agent and
flushing with clean water afterwards.
2. Replace any damaged seals and repair any leaks.
3. Completely empty the sprayer, and let the pump work for a few minutes. Operate all valves and handles to drain as
much water out off the liquid system as possible. Let the pump run, until air comes out of all nozzles. Also, drain the
rinsing tank.
4. Anti-frost protection:
A. Complete the inside and outside cleaning of the sprayer.
B. Pour approximately 50 litres of antifreeze mixture (e.g glycol and water), into the MainTank. Include any
remaining water hidden in the liquid system in the mixture.
Depending on local winter temperatures, use the recommended mixture ratio in the table below:
Temperature
(°C)
-7
-12
-20
-31
-40
C. Turn on the pump and operate all valves and functions, operating units, TurboFiller etc., allowing the antifreeze
mixture to be distributed around the entire liquid system without leaving any unmixed water in hidden places.
Unmixed water will freeze and possibly damage the sprayer components!
D. Open the operating unit main ON/OFF valve and the distribution valves, so that the antifreeze is sprayed
through the nozzles as well.
The antifreeze mixture will also prevent O-rings, seals, diaphragms, etc. from drying out.
E. Empty filters and boom pipes. Remember to unscrew the end plugs, as unmixed water can build up in blind
pipe ends causing risk of a broken end plug or pipe, when the boom pipes are pressurized at the next spray job.
After filling the antifreeze mixture, also remove the sensor
(A) connected to the nozzle pressure gauge, as this area is a
possible blind end.
5. Remove the glycerine-filled pressure gauges and store them frost-free in vertical position.
6. Lubricate all lubricating points according to the lubricating schemes - regardless of intervals stated.
7. When the sprayer is dry, remove rust from scratches or damage in the paint, if any, and touch up the paint.
