Safety Valve Activation
To make the fluid system work perfectly over time, it is good practice regularly to provoke opening of the safety valve.
This prevents clogging and ensures proper function of the safety valve. Open the valve by turning the pressure SmartValve
to “Pressure draining” or an unused function, when the pump is running. This is good practice for all sprayers; particularly for
sprayers without optional equipment.
€
DANGER! Before turning pressure the SmartValve to “Pressure draining”, it is very important to ensure correct and
complete fit of the quick coupler lid to the filling stud in its locked position. Failure to do so causes a risk of
contamination and injury from the quick coupler lid being “shot” off when pressurized! If it is not possible to fit the
lid completely, lubricate the rubber seal and the grip hooks.
Readjustment of Boom - General Info
Before commencing adjustment jobs, please go through this checklist.
1.
Keep the sprayer well lubricated (see the section “Lubrication”).
2.
Connect the sprayer to the tractor.
3.
Place the tractor and sprayer on level and solid ground.
4.
Activate the parking brakes for the tractor and trailer.
5.
Place wheel chocks under the wheels to prevent rolling.
6.
Unfold the boom.
7.
Set slanting angle to neutral position (horizontal).
8.
Place strong supports below the centre section and all boom sections to relieve the load from the hydraulic cylinders.
If you have a lifting crane, support the centre section as a minimum, as this is the heaviest boom part (up to 1000 kg).
€
DANGER! While carrying out adjustment, allow no one under the boom.
μ
ATTENTION! Boom sections not supported during an adjustment job might fall down or be difficult to adjust.
9.
Check the boom alignment.
Use a spirit level, or measure the distance to the ground from similar points in both ends of the boom wing (use this
method for horizontal alignment and only on level ground). When using the latter method, both distances should be
equal to obtain a horizontal boom.
€
DANGER! Carry out adjustment of hydraulic cylinders without pressure in the system.
μ
ATTENTION! Carry out adjustment equally for both the left and right boom wings.

ATTENTION! For information on boom terminology, see “Spray Boom” on page 62.
