a combination of high-pressure water and suction to
perform in a designated area and application. The water,
hydraulic and vacuum systems work together to provide
a powerful machine.
Prior to operation, perform daily maintenance on the unit

Overview - Hydro-excavation Operation
Hydro-excavation uses high-pressure water to
loosen soils, and the residual slurry spoils are
easily extracted into the debris body. Using water
is the most productive process, especially in rocky
soils. It outperforms air-excavation because it
moves large amounts of material faster and more
efficiently, favoring larger excavation jobs. Heated
water (optional) can be used to cut through frozen
soils. There is minimal abrasion to the underground
utilities. Water system components tend to have a
longer useful lifespan then compressed air systems.
Hydro-excavation advantages:
• In frozen ground or harder materials, water
can be heated with optional on-board water
heaters to aid in cutting through these
materials.
• Hydro-excavation equipment can often be
used for adjacent applications, such as tank
cleaning. With the on-board high pressure
water pump, hydro-excavators can perform
many alternate applications that cannot be
completed with pneumatic excavators.
• Hydro-excavation does not produce the
sandblasting effect the way air does.
This reduces the potential for damage to
underground utilities.
• Water is also a lubricant, which helps to
prolong the life of the excavation equipment
by reducing wear on the vacuum hose and
other components in the air stream.

 TRXX
Overview - Basic Operation Operation
The operational systems on the Truvac are
dependent upon the options and capacities of
the machine as ordered. The machine is custom
designed to provide a combination of compressed
air or high-pressure water and suction to perform
in a designated area and application. The water,
hydraulic and vacuum systems work together to
provide a powerful excavating machine.
It is important to remember that the vacuum tube
uses air flow and not vacuum to pick up material.
Keep the suction end of the nozzle in the upright
position to receive air and material. Submerging the
nozzle in material stops airflow, prevents material
movement and creates a loading and unloading
effect on the blower. The nozzle is designed to
pull air into the pipe to move material. The end is
serrated with small holes; if the end is submerged
no air is pulled in through the holes.
Air speed is important when working in freezing
temperatures. High air speeds cause wind chill
conditions because of the air velocity created.
The wind chill conditions cause ice build up in
the vacuum tube or boom which blocks material
movement. Proper air speed will vary depending on
the material moved. Watch the air exhaust for carry
over of material.
The further the distance from the work site to the
debris body the higher the air speed that is needed.
The shorter the distance, the lower the air speed
needed. Position unit where optimum air speed can
be achieved for the job at hand. Material moving
through a pipe or tube creates a friction factor. The
longer the tube or pipe, the higher the friction factor
called friction loss. Pipe and tube diameter is a
major factor when moving material. Lower engine/
air speed translates to lower fuel costs and reduced
noise.

 TRXX
Overview - Basic Operation Operation
You have two things that you can control; water
volume and water pressure.
Blower speed controls the volume of air and the
speed of the air through the pipe and into the debris
body. When “Dig Mode” is engaged, the blower on
the TRXX is designed to automatically run at full
RPM.
If the ground is very hard or frozen, you will not
able to move the same volume of material in these
conditions. How far away from the unit is the job
site? Material moving through a hose or pipe has
a friction factor. This value is directly related to the
amount of length of hose/pipe that the material
travels through. It can more appropriately be defined
as friction loss.
Understanding the vacuum system
The term “vacuum system” as it pertains to any
Hydro Excavator product is actually a misnomer. We
should be talking about an “air movement system”
because that’s really what it is. Air picks the
material up and carries it into the debris body.
Air must be moving in order to move material. If
the nozzle is totally submerged in the material no
air can get in. When this happens, the material is
pulled up only so high in the tube and it sits there.
In the case of a blower (PD) machine, air movement
becomes even more important because air is what
cools the blower. Restricted air flow can cause the
blower to over heat which can cause damage to
the blower. The chart below shows the percent of
restriction that is created as a six (6) inch nozzle is
closed down.

Rear Door Operation
The rear door is hydraulically opened and closed
using the control panel keypad on the passenger
side. When opening, the door locks release allowing
the rear door to then hydraulically open. Similarly,
when closing, the door is hydraulically lowered into
position tight against the debris body and the locks
lock the door.
Decant drain
Decanting is the draining of excess liquids from the
debris body, typically while at the job site. Fewer
trips to the disposal site will be needed if the excess
liquid is drained from the debris body at the job site.
This also lightens the weight of the unit.
Decanting should be done at job site for several
reasons. Excessive weight can:
• Lead to fines.
• Cause material to carry over into blower
Always check local government laws, regulations
and rules for decanting into sewers or catch basins.
The decant port if equipped with a valve allows
liquid to be drained from the debris body. First
position the unit over a manhole or near the catch
basin. Turn off the vacuum to allow the liquids to
flow out. Open the valve and drain until complete
and close the valve. If the drain port plugs with
debris the vacuum system can be used to pull the
debris clear of the port.
Be sure to check for overhead obstructions. If none,
the hydraulic controls can be used to raise the
debris body up to the height of the first stage of the
hoist cylinder when the rear door is closed.
After the excessive liquid has drained, lower the
debris body.
Note: The vacuum system must be shut down to
drain. Do not raise the debris body fully when
decanting water. Material in the debris body
can slide against the rear door and thereby
shutting off the decanting process.

Boom - Operation Operation
The TRXX boom can be configured in several
different ways. One option is no boom which utilizes

the debris body inlet. Another is a manual operated
boom which is operated by workers utilizing no
hydraulics. The third option is a hydraulically
controlled boom.
Deploying the Boom
To take the boom out of its stored position, the
boom must be raised slightly to clear the boom
cradle that it rests upon. Once clear of the cradle, it
can be raised, lowered or rotated horizontally.
The manual boom rotates freely with no hydraulics No Boom

Vacuum System - Blower Operation
The movement of air by the blower picks up
debris and water from the work site and moves
the material through a vacuum tube into the debris
body. A positive displacement (PD) blower is used
to produce the movement of air needed to transport
debris from the job site into the debris body. Due
to the change in air volume in the debris body, the
debris and water are deposited into the body, while
air is drawn through ports in the body to the blower
where it is exhausted.
Blower
The blower is the heart of the vacuum system.
Large volumes of air are displaced from the intake
side to the discharge side. This creates air flow and
allows material to be conveyed through the vacuum
hose.
The vacuum pump is driven by the chassis engine.
Its fuel-efficient, positive-displacement design
enables the unit to vacuum solids from beneath NOTICE

Freezing Weather
Any time the blower/unit will sit after use during
freezing weather the blower should be run 3-5
minutes with the 4-way valve open to dry out the
blower. This will reduce the risk of the blower
freezing up. Depending on weather conditions it
may even be necessary before the operators go to

Operations - Basic Procedures Operation
All vacuum units move material through air
conveyance. They rely on air movement to entrap
and carry away the debris. It is very important to
keep the suction end of the pipe or hose in the right
position so it is always receiving air and material.
Submerging the nozzle in the material cuts off
the air flow preventing material movement. This
also creates a loading and unloading effect on the
blower when the nozzle is lifted. This load / unload
effect can cause undue stress on bearings and
hydraulic components in the system which creates
premature failure of the component.
It is very important when trenching and digging
large holes that you work as a team. One person is
operating the wand or hand gun. The other person
is positioning the boom so the vacuum tube is in
the right position to move the material as soon as
it breaks away. It is not productive to try to wash
the material to the nozzle or to try to vacuum the
material a great distance to the nozzle.
Use the boom to lower the nozzle into the material
to be removed. With most material, it helps to move
the nozzle up and down using the boom controls.
Lower the nozzle into the material and raise the
nozzle enough for the bottom of the nozzle to clear
the material, and then back down into the material.
Using this up and down motion will help loosen the
debris, especially compacted material.
When picking up water or slurries, allow the tip of
the nozzle to just clear the top of the water or slurry.
As material is removed, the nozzle can be tipped,
or the pipe and boom moved horizontally to reach
other material. Continually working the nozzle this
way enables the operator to observe the work area.
If the material to be picked up is not in a pile, use
a shovel, rake or hoe to work the material into the
nozzle. The water stream can be used to move
material toward the tip of the nozzle.

Shutting Down Operations Operation
Operations can continue until the debris body
capacity is reached, at which time all operations
must cease.
Note: Never overfill the debris body. Normally, if it
does not exceed the GVWR (gross vehicle
weight rating), the debris body should not
be filled more than 60% - 75% of its rated
volumetric capacity.
In liquid vacuuming, the level indicator or the
change in the sound of the blower (the float ball will
get sucked up) will indicate a full tank and time to
stop vacuuming.
The unit is not equipped with an inspection port so it
is important to pay attention to the amount of debris
that has been vacuumed. Experience will tell when
the debris body is ready to be dumped. If the debris
body is full, vacuuming operations must cease.
Ceasing Operations
1. Remove the vacuum hose from the work
area. Let it suck air for some time to allow
any material still in the hose to be carried into
the tank. Then run some water through the
suction tube to clean the inside of the suction
tube, hose and boom.
2. Disable the vacuum and shut down the unit.
3. Disconnect water wand or high pressure hand
gun and store them in their respectful places
on the tongue of the trailer.

Cleaning - Debris Body Operation
Set the rear door safety props to secure the door
from accidentally falling during cleaning operations.
Using the handgun, wash out the debris body,
paying particular attention to the door seal, lock
bolts, level indicator, float balls, vacuum enhancer (if
equipped), etc. and the inside of the rear door.
Visually inspect door seal. The door seal and mating
surface on the debris body should be completely
cleaned so it forms a complete seal when it is
closed.
Lower the debris body to the down position. Lower
the rear door and wash the rear door and rear of
the unit. The rear door must close with an air and
watertight seal. Make sure all debris is removed
from the seal before closing the door.
Turn off the water pump and put the wash hose and
gun away.
Lowering Debris Body/Closing Door
Rear door Seal
After the debris body has been emptied and the
seal cleaned, store the rear door props and lower
the body to its original operating position.
Disengage the hydraulics.
The body should always be lowered first and then
the door closed. Never raise a loaded body unless
the rear door is open and you intend to empty the
debris body.

 TRXX
Cleaning - Cyclones (Optional) Operation
A cyclone separator uses air turbulence to remove
dirt and debris from the airflow and deposit it in
bottom of the separator.
Air leaving the float-ball vacuum shut-off in the
debris tank enters the cyclone housings located on
sides of the unit at the rear of the debris body. It
protects the blower by removing material from the
air stream before it reaches the blower.
The cyclone spins the air stream around the walls
of the housing until it reaches the bottom of the
cyclone house. The cyclone reduces particle matter
in the airstream leaving relatively clean air to return
to the top of the cyclone and in to the final filter.
The vacuum filtration system requires some specific
cleaning for optimal operation. When a job is
completed, or the unit will be driven and parked
between work, or there will be more than a shift
of downtime between work, the cyclones need
to be cleaned. Some special conditions such as
high humidity combined with certain materials may
require more frequent cleaning.
The cyclones and all areas in contact with the
moving material should be inspected monthly and
repaired or replaced as required. Highly abrasive
and/or corrosive materials will require more frequent
inspections. Wear rates can be increased due to
high operating RPM's. Material composition is also a
primary factor in increase wear rates.
The cyclone separator should be inspected daily
for dirt, dust and debris. Inspect the separator more
often if working on jobs with excessive dust, dirt or
debris.
Biological hazard
! WARNING
Always stand to the side when
opening the clean out door.
While standing to one side, open the separator door
and allow the debris to fall out. Inspect and remove
any remaining debris inside the separator.
Use the hand gun to thoroughly wash the cyclone
separator and door. Make sure the door seal is
clean and clear of any dust, dirt and debris.
For the cyclone separator to function the door
seal must be clean and seal properly. Check the
separator door seal by applying a thin layer of
grease to the seal and closing the door. When
the door is opened a complete imprint of the seal
should be left on the frame. If the imprint does
not reflect the entire seal the door is not sealing
properly. Inspect the door, seal and frame for wear
or damage and repair or replace as necessary.

Debris Body - Safety Prop Operation
At any time the debris body is raised to obtain
access to the underside of the debris body, all
safety precautions must be followed. The debris
body should be stabilized and secured before
entering any space below it. The unit should be
parked on a flat level surface.
1. Raise the debris body so that the front of
the body clears the safety prop or as shown.
Release latch and tilt the prop in to position
after dumping.
Note: It must be high enough in the air to allow
the safety prop to clear the body and swing
fully into position with the prop rest under the
body.
2. Rotate the safety prop towards the prop rest
until the stop-cable stops it.
3. After the top of the prop is in position, lower
the body until the prop tab is just into the slot.
Do not power the debris body down on to the
prop. This will secure the body from falling.

cleaned each time the hydraulic oil is changed.

Note: The hydraulic reservoir contains approximately

20 gallons of oil. When draining the reservoir, a
suitable container must be used to hold the oil
and prevent spills. It may be necessary to drain
the reservoir a small amount at a time.
Change the Hydraulic Oil and Clean the Strainer
1. Place a suitable container below the hydraulic Hydraulic
reservoir and remove the drain plug from the Oil Tank

Boom Hose Replacement Maintenance

Replacement of the boom hose is made by rotating

the boom out towards the rear of the unit so that the
boom is aligned/straight with the debris body inlet.
Drop the boom down so the hose goes across the
boom pivot. This is the longest distance the hose
has to make. After removing the old hose verify
the new hose is the same as the old one before
installing. Failure to utilize the same hose may
result in kinking at the bend radius.

Note: Store all replacement boom hoses spread out

straight to avoid inducing a preset memory
to the hose which can happen when stored
when coiled.

Blower Maintenance
For blower description, maintenance and operation,
see the blower manuals supplied with the vehicle.
Freezing Weather
Any time the blower/unit will sit after use during
freezing weather the blower should be run 3-5
minutes with the vacuum relief open to dry out
the blower. This will reduce the risk of the blower
freezing up. Depending on weather conditions it
may even be necessary before the operators go to
lunch and at the end of the daily operation.
Oil Level
There are normally two sight glasses on the blower.
Locations will vary with the blower model and
manufacturer. The unit should be on level ground
and off. The oil should be filled to the center of
these sight glasses.

For complete maintenance see the blower manuals

supplied with the vehicle.

Belt and Sheave Alignment Maintenance
Belt and Sheave Alignment
Proper belt and sheave alignment is important for effective use of the HXX system. Misalignment can result
in belt(s) coming off of the pulleys or premature belt failure. Proper aligment is achieved through angular and
parallel measurement of the pulleys, as well as accurate adjustment. Alignment procedures are included below
to achieve proper alignment.

Proper alignment assures:

1. Reduced belt/sheave wear and tear
2. Reduced friction, noise, and vibration
3. Reduced machine maintenance
4. Increased bearing and overall machine life

Blower V-belt P/N: 514219-30

Water Pump V-belt P/N: 514219A-30

Alignment Measurement
A laser alignment device is the most ideal tool for aligning the sheaves; refer to its
operator’s manual for its model-specific instructions. When one is not available, alignment
is measured by taking a straight-edge to the sides of both sheaves. The straight-edge may
be a level, a ruler, or anything known to be straight that can span the distance across the
sheaves. The straight-edge must make contact at four distinct points in a line along the
outside of the sheaves (see picture). Any gaps between the straight-edge and sheaves can
indicate misalignment and require adjustment. Refer to the chart below to recognize which
misalignment, if any, is present.
Note: The technician must confirm that the sheaves’ outer edges (measuring surface)
thicknesses are equal, or, take note of and apply the difference since this will affect
the measurement.

Refer to the specific belt manufacturer’s guidance for

acceptable terms of tension, wear, and misalignment values.

Effective Date April 4, 2025 155 TRXX Belt and Sheave Alignment
 TRXX
Belt and Sheave Alignment Maintenance
Alignment Measurement continued:
Angular misalignment is measured by determining the difference
between two points (Measurements 1 and 2, M1 and M2,
respectively) over a given distance (D).
Arc Tan is used to find the value of an unknown angle (Red) of
a right triangle when its legs (the perpendicular and base) are
known. The difference of M1 and M2 is the perpendicular of the
triangle while D is the base.
The end result is a quantified value of angular misalignment
(θ, Theta) measured in degrees (°) which can be reduced or
eliminated through proper adjustment of components’ positions or
adjusting the sheaves’ positions, themselves, on the components.
This angular misalignment must be reduced to acceptable
amounts to avoid the aforementioned symptoms.

Rule of Thumb Aligment Tolerances: Example: θ = Arc Tan ((1 - 0.5) ÷ 57.34)
1. Synchronous, urethane 60-degree belts can endure θ = Arc Tan (0.5 ÷ 57.34)
up to one-quarter (1/4, 0.25°) of a degree in angular
misalignment. = Arc Tan (0.00873) θ = 0.5°

2. V-Belt designs can endure up to one-half (1/2, 0.5°) of a

degree in angular misalignment.
For synchronous, 60-degree angle, and V-ribbed drives:
1/4-degree angle = approximately 1/16-inch per foot of distance traveled.

For V-belt drives:

1/2-degree angle = approximately 1/10-inch per foot of distance traveled.

Sheave Position Adjustment for Alignment

For adjusting the sheaves, the “parallel” adjustment can be fine tuned by removing the three (3) bolts from the
sheave, removing the sheave, and moving the bushing before re-assembling. While re-assembling, check the
parallelism of the sheaves before finally re-tightening the bolts.

See diagram for items and their respective torque specifications.

Belt and Sheave Alignment Maintenance
Component Posistion Adjustment for Alignment
Horizontal angle misalignment can be solved by loosening the base of the component needing adjustment,
setting it in place, and re-tightening the bolts.
For the water pump, there are 4 bolts surrouding its
underside securing it to the mount. These can be loosened
to re-position the pump.

See diagram for bolt locations and note for tension.

For the blower, there are 4 bolts securing it to the mount

and 4 bolts mounting the mount to the base. These
can be loosened and the blower, and its mount, can be
shifted independently for fine adjusting to align the belts.

See diagram for bolt locations and note for tension.

The tensioners are adjusted by loosening both bolts

(star location and one located above and behind the
unit) on the mounting bracket, using a large wrench
or crescent wrench to adjust for proper belt tension
(see notes), then re-tightening the two bolts on the
mounting bracket.
The idler pulley bolts are torqued to: 60 Ft-lbs. (LBF)
The tensioner mounting bracket bolts are torqued to:
60 Ft-lbs. (LBF)

Vertical misalignment can be indicative of other present problems. Before alignment, check all present
components for damage or wear and tear. Replace if beyond serviceable condition.
Vertical misalignment can be reduced or eliminated by shimming the component and/or mount. This can be
accomplished with washers between the components and/or mounts, as needed, to re-align the components
within acceptable tolerances. Use sound judgment when shimming.

This will eventually wear it out. The tolerances
between the moving and stationary parts in a

Water System - Overview Troubleshooting
The water system is the component that allows the
hydro-excavation feature to function. This system
includes the following items:
• Water tanks and associated plumbing
• Y-strainer
• Water pump
Water
• Water pump clutch & drive belts Pump

• Unloader valve
• High pressure hose reel
• Handgun & nozzles
Watertanks
The water tanks are located on each side of the
debris body. The tanks can be filled a couple
different ways. All models come with an expansion
plug on the top of each tank and can be filled via
any water source. Optional fills include air gaps
held on with band-lok clamps that have provisions
for hydrant/high volume filling.

Water System - Water Pump Troubleshooting
The water pump is rated at 5 gpm. However, the
nozzle size at the end of the handgun will determine
actual flow of the unit. A shut-off vlave controls
water flow between the tank and pump. A y-strainer
is located next to the pump. The strainer must be
kept clean and should be checked before each
use. Water flows into the pump and is pressurized.
Proper knowledge of the water system in its entirety
is necessary for troubleshooting issues. See
system details below:
1. Water flow shut-off valve
2. Y-strainer
3. Y-strainer drain
