If there is a reduction in foam produced from the lance head,
you will not achieve the desired kill. You can check this by
lifting the lance and observing the water flow.
10.4 Treatment of thick weeds
The Foamstream system works by penetration of heat into
plant cells. In cases of dense growth and dense swards of
grass (especially species such as kikuyu), progress will be
slower as a greater volume of liquid (thermal energy) is
required to ensure a result.
10.5 Confirmation of treatment
With

operators
determining whether weeds have been treated correctly.
Broad leaf weeds will go floppy and wilt (similar to boiled
cabbage). In most cases these will go darker in colour.
Grasses: usually, grasses immediately lighten in colour and
flatten to the ground. This can be difficult to observe when
using hot foam.
Moss will go bright green.
In all cases, a distinctive smell (similar to cooking spinach)
also assists to confirm a result.
VISUAL CONFIRMATION THAT THE TREATMENT HAS BEEN
SUCCESSFUL IS ESSENTIAL.

10.6 Correct posture
When using the equipment for several hours per day it is
important that operators adopt the correct posture and
technique.
Remember it is the heat that controls the vegetation.
When treating straight stretches of roads or parks, use just
the trigger hand to guide the lance. This keeps your back
upright and not twisted and you are not encouraged to push
down with the other hand. Optional wheels are available.
Only use the other hand when changing direction or raising
the lance.
When walking, swap trigger hands every so often to rest the
muscles.
