Before Spraying; To Start Spraying - Micron Herbi4 Instruction Manual

BEFORE SPRAYING

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. Never spray into the wind
and avoid walking into the spray. Always 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 only 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, pref-
erably 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').

N.B. To help aid the balance of the sprayer, while using the 2 / L Bottle, a Shoulder

strap is provided.

TO START SPRAYING

Hold the spray head about 20cm above the ground or weed foliage. Switch on the
sprayer, check the atomiser disc starts spinning (never 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. Do not 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.
