STORAGE
Before storing the HERBIFLEX-4 for long periods disassemble the sprayer by re-
moving the four screws in the battery case and clean all electrical contacts with a wire
brush or similar. Reassemble and with the sprayer in the collapsed position i.e. bat-
teries removed, store in a dry place away from direct sunlight. Batteries should be
stored in a dry place away from direct sunlight.
OPTIONAL EXTRAS
Spray shield
In some instances where it is essential to
minimise any spray drift a spray shield can
be used. This should only be used with the
standard atomiser cone housing A90.
To fit the spray shield, remove the head adjustment wingnut and screw. Slip the
shield over the spray head so that it sits around the top of the motor housing. Fit the
screw, washers and wingnut provided with the spray shield to secure it and set the
angle of the spray head.
Atomiser cone B120 (for wider swaths)
If wider swaths (up to 75 cm) are needed an atomiser cone housing with a wider
opening (B120) should be used. This is supplied with a set of feed nozzles (yellow,
orange and red) which give the higher flow rates needed for treating using wider
swaths. (see 'MIXING, FILLING AND CALIBRATION').
This should be fitted as described in 'AFTER SPRAYING - TO REFIT THE AT-
OMISER DISC.'

For example, if the label recommends applying a minimum of 2 litres of product
made up to 200 litres of water per hectare with a knapsack sprayer, use 2 litres of
product made up to 20 litres for application with the HERBIFLEX-4, i.e. a spray mix
concentration of 10%.
Do not
use herbicide concentrations greater than the maximum recommended on the
label (unless specific training or recommendations have been given) if the label:
a)
specifically prohibits use of 'Reduced Volumes' i.e. increased concentrations;
b)
has a statutory requirement for use of personal protective equipment when
using the diluted product at high volumes (N.B. this will appear in the
statutory box on the label); or
c)
carries one of the following hazard ratings: 'very toxic', 'toxic' or 'corrosive' or
carries the warning 'risk of serious damage to the eyes' e.g. paraquat
(Gramoxone) which is classified as toxic should not therefore be used through
the HERBIFLEX-4 at concentrations greater than recommended on the label.
Micron do not generally recommend using spray mixes more than ten times the
maximum concentration recommended for high volume application with knapsack
sprayers. The safest product and lowest dose rate appropriate for the treatment
should be used at all times.
To prepare the spray mix first read the product label to determine the quantity of
product to be applied per hectare e.g. 2 litres of glyphosate per hectare. Then
determine the total spray volume to be applied per hectare with the Herbi-4 i.e. 10 or
20 litres per hectare. Calculate the ratio of product in water e.g. 2 litres glyp
8 litres water = 10 litre mix = 1: 4. Use this ratio to prepare the correct dose for the
spray tank or bottle e.g. with a 5 litre backpack mix 1 litre glyphosate with 4 litre of
water.
Half fill the tank with clean water and
check for leaks
Measure out the exact amount of prod-
uct and add to the tank
