Rainbow Treecare HTI 2000 - Overview of Your HTI 2000; Preparing for Application; Determining DBH; Priming the HTI 2000

Overview of Your HTI 2000
The HTI 2000 is a lightweight, accurate soil injector that avoids the need for a flowmeter Specifically designed to apply
Cambistat, this soil injector can also be used to apply Xytect, Lepitect, Transtect, and other tree health products where accuracy
is critical.
Equipment Needed:
• DBH Tape
• HTI2000 Soil Injector
• Pump System OR
• Motorized Backpack Sprayer
• PPE (see product label)
Preparing for application
1. Accurately measure the trees diameter at breast height (DBH).
2. Follow instructions on product label for mixing rates.
3. Be sure to wear proper personal protective equipment (PPE)
in accordance to the product label.
Priming the HTI 2000
1. Ensure that the pressure is turned OFF, and connect HTI to
pump/backpack sprayer via quick-connect connections. HTI
will not connect if pressure is turned on.
2. Start the pump. Pressure to the HTI should be maintained
between 85 – 150psi.
3. Circulate product or water that is resting within the HTI 2000
by filling the HTI and injecting it back into pump/backpack
sprayer for 8 cycles (2000ml).
a. Hold down the fill button until the volume meter reaches
its full capacity (250 ml).
b. Hold down inject button to release the product into the
apparatus that contains the product. This ensures that
the correct product is being applied.
• Single Stem (Fig. 1) Measure the standard DBH of the tree
• Individual Trees in Close Proximity (Fig. 2) Measure the
DBH of each stem and treat each tree individually. Note any
dose reductions due to the overlapping canopies.
• Multi-stem Split at or below DBH (Fig. 3) Measure the tree
at the narrowest point between the root are and the split.
• Tree Splits at or Above DBH (Fig. 4) Measure the DBH of
each stem and add the measurements together and
measure the narrowest point below the split. Take the
average of these two values.
• Stem Clusters (Fig. 5) Measure the DBH of each stem and
add the measurements together. Note any dose reductions
due to the overlapping canopies.

NOTE: The foot peg can be loosened
to change the direction it faces. This
allows the applicator to fit the HTI in
tight spaces or to use the equipment
in their own ergonomic preference.
