Every 10 working hours – Nozzles
To clean or replace the nozzles, use a spanner to undo the nut (D).
Remove the nozzle and clean it with air, water or a toothbrush.
μ
ATTENTION! Never use a piece of wire or a needle as this could
cause irreparable damage to the nozzle.
If any of the nozzles leak when closing the spray section valve, the non-
drip diaphragm should be replaced (E). The nozzles should be replaced
when their unit flow varies more than 10%. Worn or damaged nozzles
may cause crop damages or insufficient results.
Every 50 working hours - Pressure pulsation damper
The 321 pump is fitted with a pulsation damper on suction and pressure
sides. The pressure side damper is pressurized. The dampers will reduce
pulsations and secure an even flow from the pump.
The pressure pulsation damper should be inflated to the pressure
shown in the table on top of the pulsation damper (A).
Every 50 working hours - Diaphragm pump
Grease the pump after every 50 working hours or once a month,
through the grease nipple located at the crankshaft end. The grease is
distributed through the crankshaft to ball bearings, connecting rods, etc.
±
WARNING! A lack of grease in the pump could cause it to
overheat and destroy moving parts.
