Forward Speed
The forward speed used should be proportional to the amount of weeds being encountered. In areas of thin weed growth, a faster speed (for
example 8kmh [5mph]) will result in an effective kill and improved workrate. Conversely, in areas of thick weed growth, forward speed will need
to be reduced to a slow walking pace in order to effectively wipe all the weeds.
Storage
The machine should be thoroughly hosed down with clean, low pressure water and lubricated after use to prevent corrosion due to herbicide
residue left on the machine. The machine should only be put into storage once fully dry, and should be kept under cover when not in use.
Wiring Colours
In cases where the plug /socket or wiring has been damaged, the wiring may need to be checked, the following colours are used:
Red = Pin 1 =
Green = Pin 2 =
Brown = Pin 3 =
White = Earth =

Possible Causes
Poor connection
Shortage in wiring (may be indicated by

pressed)
Motor Fault
Poor connection
Pump overheated
Pressure regulator incorrectly set
Faulty Pump
Application rate too high for level of
weeds being encountered

atomise spray correctly, especially
notable on outermost nozzles)
