The HERBIFLEX-4 can be used to apply bands of herbicides around buildings, fence 
lines, borders and pathways as well as for treatment between crop rows.  The weight 
of the machine ready to spray, with the 

Micropak

 5 litre backpack, is 7 kg. 

 
Specially designed Micron 

Micropak 

backpacks and a shoulder strap are available for 

use with the HERBIFLEX-4.  Other optional extras include an atomiser cone housing 
(B 120) which allows a wider band to be sprayed and a spray shield (for use with the 
standard A90 atomiser cone housing only).   
 
The sprayer can also be supplied with a valve/handle conversion, as the HERBI-
FLEX-4 Extra, which allows Micron spray bottles to be fitted directly to the sprayer. 

SAFETY 
 

Using agrochemicals is a hazardous process.  Operators should comply with all 
relevant legislation and/or regulations governing the use of agrochemicals and should 
use appropriate personal protective equipment (see 'OPERATOR PROTECTION').  

Never

 use the HERBIFLEX-4 in potentially explosive atmospheres or spray 

flammable liquid through it. 
 
The HERBIFLEX-4 can be used with most conventional herbicides, as well as 
specific CDA formulations (only available in some countries) to provide a closed 
transfer system to improve operator safety. 

Never

 eat, drink, or smoke when working with agrochemicals.  After using 

agrochemicals or handling equipment wash your hands thoroughly.  Keep people 
(especially children) and animals out of areas being sprayed. 
 

Always

 store agrochemicals safely to protect people and animals, and to safeguard 

the environment (take special care to avoid water pollution).  See spraying sections 
for guidelines on safe use of the HERBIFLEX-4 in operation.

 read the product label carefully to
