Safety valve activation
To make the fluid system work perfectly over time, it is good practice to regularly provoke opening of the safety valve.
This avoids clogging and ensures proper function of the safety valve. This is done by turning the pressure SmartValve to
“Pressure draining” or an unused function when pump is running. This is good practice for all but particularly for sprayers
without optional equipment.

DANGER! Before turning pressure SmartValve to “Pressure draining” 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.
Grease the ProFlow valve (optional)
If the ProFlow valve works tight, it should be greased. This is done at the
two nipples on the upperside of the valve which is located behind the
valve cover at the place where ProFlow external filling handle is. It is
possible to reach out for the nipples between the valve cover and the
EasyClean filter.
Greasing
Turn the nipple one turn clockwise around to grease the valve. When
the nipple cup cannot be turned further in (=empty) then turn it
counterclockwise to dismantle it. Then refill the cup with grease and
reassemble to the nipple. Use universal lithium grease, NLGI No. 2 (e.g.
SHELL RETINAX EP2).
