DESCRIPTION

The HERBI-4 is a simple robust hand-held spinning disc Controlled Droplet
Application (CDA) sprayer powered by 4 torch (D-cell/R20) batteries, with one set of
good quality batteries giving over forty hours spraying time. It is designed to apply
herbicides in a 1.2m wide band at low volumes (10 to 30 litres/hectare). A governed
electric motor spins the atomiser disc at a constant 2,000 rpm to produce uniform spray
droplets of around 250 micron; large enough to minimise any risk of spray drift. Liquid
is fed by gravity through colour coded feed nozzles. The HERBI-4 can apply
herbicides to borders, pathways, ditches and larger areas by making a series of
consecutive spray passes. The weight of the machine ready to spray, with the ST 10
litre backpack.

A) Atomiser disc spins but does not spray or sprays irregularly. Check:
- The feed nozzle. If the feed nozzle is blocked remove and soak in soapy water.
blow through the nozzle with your mouth. Check that the feed nozzle

gives a flow rate within the operating range.
- The atomiser is clean and undamaged. Clean or replace.
- The flow valve for blockage. Rinse through with soapy water.
B) Atomiser disc fails to spin or spins unevenly. Check:
- That the batteries are fitted correctly.
- The condition of the batteries. Replace if necessary.
- That electrical terminals and contact points are clean and that electrical wires are
not broken or corroded.
- If the atomiser disc is rubbing on the motor base plate or the motor shaft is bent.
Replace the disc or motor if necessary.
- The motor for corrosion or obvious signs of wear. Replace if necessary.
N.B. Battery condition can be checked with a torch (or a torch lightbulb and electrical
wire).
