BoomPrime One-Way Valve

If the one-way valves for the BoomPrime system are clogged, they must
be cleaned.
1. Disassemble the two parts.
2. Clean the parts as needed. Check the state of the black O-ring.
3. Assemble the parts again and tighten with a torque of 1 Nm.
μ
ATTENTION! If any part is worn or damaged, it should be replaced.

Adjustment of 3-Way Valve

The large ball valve (type s93) can be adjusted, if it is too tight to
operate - or if it is too loose (= liquid leakage).
• Correct setting is when the valve can be operated smoothly by one
hand.
Use a suitable tool and adjust the toothed ring inside the valve as shown
on the drawing.
μ
ATTENTION! The small ball valves (type s67) cannot be adjusted.

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 prevents clogging and ensures proper function of the safety valve. Opening of the valve is done 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 SmartValve to "Pressure draining", it is very important to be sure that the quick
coupler lid is correctly and completely mounted 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 mount
lid completely, lubricate the rubber seal and the grip hooks.
