Chapter 5 - Operation
5 Operation
This chapter describes how the HOAF
thermHIT® 75M/100M/125M is operated.
5.1 Important
•
Only use the
HOAF thermHIT® 75M/100M/125M
in the open air.
•
Do not use the
HOAF thermHIT® 75M/100M/125M
in extremely rainy and
windy circumstances; the results will be substantially worse than under dry
and calm weather conditions.
•
Do not use the
HOAF thermHIT® 75M/100M/125M
on flammable, dry crops.
•
In order to avoid damage to the soil, you have to start driving the
HOAF
thermHIT® 75M/100M/125M
immediately upon firing it up.
•
Drive the
HOAF thermHIT® 75M/100M/125M
slowly enough to heat the
weeds, but not so slowly that they catch fire. The working speed depends on
the type and the density of the weeds that are to be treated and the weather
conditions.
•
It is not the objective to burn the weeds. It is only necessary to heat up the
weeds to a temperature of approximately 70ºC, causing the plant to dry out.
You can use a finger pressure test to determine whether the treatment was
sufficient (see section 5.2.3).
•
Do not burn for more than 5 seconds in the same spot, to avoid damage to
the soil and overheating of the burner.
