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.

Application
1. Inspect tree for defects (cracks, cankers, root decay/damaged root flares)at the
base and trunk as these may impede the uptake of the product into the tree.
2. Inspect for organic material (mulch) at the base of the tree. Mulch can aect the
uptake of the product by the tree by not allowing the product to reach the soil.
Additionally, mulch obstructs the application sight line which may result in poor
product distribution in the soil.
3. If mulch is present, move it away from the base of the tree and application area.
4. Place probe 6” (up to foot peg) into soil as close as possible to the tree trunk
without hitting root tissue.
5. Fill HTI 2000 by holding down the fill button until the desired volume is achieved
6. Hold down the inject button to apply product to the soil. Volume meter will show
progress of ejected product. If at any time the volume meter stops while holding
the inject button or product becomes visible from soil, release the inject button
and finish injection at a new site.
7. If product is visible from soil, use the probe to poke holes around the area where
product is present to allow it to reach the soil.
8. Once the chamber has been fully evacuated, the digital injection counter will
automatically keep track of the number of injections performed.
9. Repeat this process and evenly apply the product around the base of the tree for
best results
10. When the application is complete for each tree, press the reset button to set the
counter back to zero
11. If organic material was removed before the start of application, move the soil
back into position.
• Products dier in total volume and concentration. In some
cases it may be more beneficial to use (8) 125ml application
doses versus (4) 250ml doses to more accurately distribute
the product around the tree.
• Never assume bare soil rests beneath mulch, rocks, or
landscaping. Products can rest upon black landscaping liner,
thus preventing the product from reaching the soil. This may
runo during precipitation events which can increase the
risk of aecting non-targeted species such as grass or other
plants in the vicinity.
• Make sure to monitor the uptake of the product into the soil.
If the product continues to bubble up and the soil is
oversaturated, it may be best to skip that tree and come
back to it at a later point in time.
• Do not apply if the ground is frozen. Uptake will be inhibited
and results will be unpredictable.
Application Tips:

Place treatment
close to the base
of the tree
Space application sites
evenly around the tree
Inject these sites first
Treatments are applied as close to the tree as
possible without damaging the roots or bark

General Care and Upkeep
1. DO NOT run fertilizers through HTI 2000. They are too
abrasive on the aluminum and will rapidly clog the filter.
2. Clean after each day of use following the
recommendations outlined in the cleaning section
of this manual.
3. Do not store or use below freezing temperatures.
4. Do not operate the HTI 2000 when the tank reservoir
is empty as it may continue to indicate the chamber
is filling. When the HTI 2000 is drawing upon an empty
reservoir there is a noticeable change in performance.
5. Probe tip will wear with use. Replace when worn to
prevent particulates from clogging product outflow
ports (see below).
Maintaining Your HTI 2000
Daily Cleaning
1. At the end of the application day, run 2000ml of
water through the HTI 2000 using the same fill and
inject buttons as application.
2. Using proper PPE, remove filter from the inline filter
housing and rinse it o to make sure any sediment
is removed from the wire mesh as a clogged filter
will impede application of the product.
3. Store in dry area above 32F and below 110F. Ensure
that no material is present in the injection cylinder
before storing.
4. Leave filter cap removed to prevent rust and
encourage drying.
End of the Season
Here is a list of advice for winterizing and keeping your HTI in shape for spring:
1. Clean all dirt and debris from the exterior of the HTI
2. Cycle clean water through the HTI - recommended minimum: 1 gallon, about 16 cycles
3. Remove the filter from the filter housing and clean with a wire brush to remove rust and debris
(battery post cleaner or other metal wire brush will also suce).
4. Store the filter separately in a clean and dry location until use the following season to prevent rusting.
5. Remove & clean rust and debris from the injection probe tip. It is recommended to store this part separately in a clean and dry area.
Consider replacing if worn.
6. Lubricate all O-rings, especially in the piston manifold, with a synthetic silicone lubricant (i.e. Molykote 111 or Super Lube).
7. Lubricate the ‘Fill and ‘Inject’ button components with synthetic silicone lubricant (i.e. Molykote 111 or Super Lube).
8. Always allow the HTI to dry as much as possible before long-term storage. An air compressor can be used to help dry the
interior of the unit.
9. Store the HTI upright to help prevent any trapped moisture from pooling in the unit.
10. Store the HTI above freezing. Freezing temperatures will cause any moisture in the unit to freeze and expand, which may
crack the piston manifold and/or damage the tubing.

Replacing Probe Tip
Frequency of use and local soil conditions will aect how often the probe tip
needs to be replaced. Inspect weekly and replace when needed.
1. Use a vice grip to unscrew probe tip.
2. Inspect tip and shaft for particulates or clogs. If either are present,
use a paper clip to remove particulates and clogs. Replace worn out tip.
3. Use vice grip to screw probe tip back on.

Troubleshooting Guide
INJECTION CYLINDER NOT INJECTING OR INJECTING AT SLOW RATE
Too low of pressure 1. Check the hose connecting the backpack or pump to the HTI to
make sure that it is not kinked. 2. Make sure that the ends of the
hoses located within the manifold are not loose, tighten them if need
be. 3. Check to make sure that the filter is not obstructed. 4. Turn up
pressure (do not exceed 175 psi).
Compressed soil/rocks at
injection site
Move probe to new application site
Clogged product outflow ports Pick out the 4 hole injection ports with a paper clip. Ensure prod-
uct is properly diluted as thicker products can impede movement
throughout HTI.
INJECTION CYLINDER NOT FILLING
Kink, twist or obstruction in
hose
Remove obstruction
Clogged inline filter Check for debris, residues or particulates. If present, clean out filter
using methods outlined within the manual.
Fill button wont activate Remove, lubricate and clean fill button components
Injection Cylinder stuck O-Rings are dry and need to be lubricated or have rolled back on
themselves causing a seize. If they have rolled back, remove the
o-ring and replace. Operating the HTI at high pressures will some-
times cause the O-ring to roll back on itself. If O-ring continuously
rolls back on it itself, adjust the pressure to lessen the likelihood of
this occurring.
CYLINDER WON’T STOP FILLING
Fill button depressed and
won’t come back up
Pressure is too high. Keep pressure below 150 psi.
Fill button on too tight Untighten the button to alleviate the dowel pin.
Spring no longer maintaining
pressure against nylon ball
Replace the spring. For a temporary fix, pull the spring apart to get it
back to original form. It is necessary to replace the spring in the long
term as the spring will have lost its integrity after repeat alterations.
Nylon ball is too worn Replace nylon ball of all of the fill button components
Port where fill button compo-
nents insert into manifold are
worn and will not hold a seal
Replace the manifold.
CYLINDER IS LEAKING
Freeze/thaw damage Replace cylinder.
O-Rings worn out Replace O-rings.
ELECTRONIC COUNTER STOPS WORKING
Water Damage Replace Counter
Dead Lithium Battery Replace Counter
Lost Connection Remove 4 screws that hold counter. Pull out of frame and check
connection
