Pressure draining (optional)
It is possible to drain to an external tank. This is done the following way:
1. Connect a hose from an external tank to the pressure quick
coupler on the sprayer.
2. Turn the Pressure SmartValve towards “External tank”.
3. Turn the suction valve towards “Main tank”.
4. Engage the P.T.O to start the pump.
5. When tank is drained then turn off P.T.O. again.
6. Disconnect hose and refit the quick coupler lid.

DANGER! Before turning Pressure SmartValve to “Pressure
draining/TurboFiller” it is very important to be sure that the quick coupler lid is correct and completely mounted to
the filling stud into its locked position. Failure to do so may cause risk of contamination and injury from quick coupler
lid being “shot” off when pressurized! If not possible to mount lid completely, lubricate the rubber seal and the grip
hooks.
Outwards cleaning - Use of External Cleaning Device (optional)
Use the External Cleaning Device to wash everything on the outwards side of the sprayer.
1. Swing out the hose reel. Cleaning gun is located in the holder at
the frame.
2. Un-roll the hose from the reel.
3. Engage pump at approximately 300 r.p.m. or 560 r.p.m. (depen-
ding on pump model).
4. Turn suction Valve towards “Suction from Rinsing tank” and
pressure SmartValve towards “External filling device” or not used
function.
5. Turn agitation valve towards “External Cleaning Device” and clean
sprayer.
6. After cleaning then close the agitation valve again.
7. Roll the hose to the reel again and swing reel to storage position.

ATTENTION! If the safety valve is activated, then lower P.T.O. revolutions to avoid rinsing water being lost into main
tank.
