BEFORE SPRAYING
Always
TO START SPRAYING
Do not
Check the wind speed and direction (below 5 kph) is safest. Take special care to avoid
drift by keeping the spray head as low as possible. spray into the wind and avoid
walking into the spray. keep the spray head at least 60cm from any part of the
body to avoid direct contamination by the spray.
Before spraying for the first time use water to check the spray pattern produced.
Put some clean water in the tank and add a small amount of detergent. Check for leaks.
Switch on the sprayer and then open the flow valve. Spray on one spot, preferably on
clean dry concrete, for around 30 seconds with the spray head held about 20cm above
the ground; a wet ring 1.2m wide should appear on the ground. Practice using the
sprayer by walking along a few metres and then stopping spraying (see ‘TO STOP
SPRAYING’).
Hold the spray head about 20cm above the ground or weed foliage. Switch on the
sprayer, check the atomiser disc starts spinning ( touch the atomiser disc when
spinning or hold the spray head too close to the operator) and then open the flow valve.
Start walking immediately the spray liquid reaches the feed nozzle. N.B. with the
HERBI-4 Extra both flow valves must be opened.
The HERBI-4 is normally held at an angle of around 35° to 40° to the ground with the
head inclined slightly away from the operator. spray with the HERBI-4 held on
the shoulder, since spray may contaminate the operator. N.B. the machine will not
spray with the spray head above the level of liquid in the tank.
