Operation
Ensure that the operator is suitably qualified to use a machine of this nature and handle chemicals (inc. suitable sprayer qualification) and that
they have fully read and understood this manual. It is advisable that all 'first time' operators familiarise themselves with operation using clean
water only at first.

Chemical Application Rate
The chemical used should be approved for use in Weed Wipers (eg. Bayer Round-up Power-Max) and the chemical should be diluted in
accordance with the product label. If in doubt check with the chemical supplier representative. As a guide, a typical dilution ratio for glyphosate
would be between:
•
20:1 – For cooler conditions or outside of the main growing season.
•
40:1 - For warm conditions during the main growing season.
The stronger the mix used the less liquid you want on the wiper brush roller; as a guide if using at 20:1 when the roller is completely stopped
you would expect some dripping to occur after approximately 20 seconds, and at 40:1 the dripping would occur after approximately 5 seconds.
Ultimately the operator must use their own discretion and chemical knowledge to balance dilution rate, application rate and forward speed in
order to get effective coverage without unnecessary chemical usage or overkill.
Control Module
ON/OFF: Switches the control box on or off. When switched on, the
applicator roller will run continuously.
APPLICATION RATE: The desired spray rate is set using the up/down arrows,
with the current output value (between 0 & 100) displayed on the 3-digit
display. For example, the machine will run for 50% of the time when set to
50 on the control box. RECOMMENDED START VALUE = 15%
PUMP RUN: Switches the sequenced pump on or off so that chemical is
applied to the applicator at the application rate set.
PURGE: This runs the pump continuously when pressed, ideal for clearing
blockages, purging the system of air or when flushing through with water
after use.
Procedure
1.
Switch the unit on by pressing ON/OFF. The display will light-up and the roller will rotate.
2.
After approx. 3 seconds the display will show the previous application rate last used between 0-100. Use the UP / DOWN arrows to
adjust if required.
3.
Press the PUMP RUN button to commence the application of herbicide.
4.
The machine will continue to run at this rate until the control is turned off or the amount is altered.
5.
When finished, switch off by pressing ON/OFF. The unit should always be cleaned with fresh water and the tank purged when
application is finished, to prevent crystallisation of the chemical in pipework and nozzles.
