sysTeM cOncepT
The Titan 875’s system utilizes an internal combustion engine to provide the power
necessary to turn both the vacuum blower and the high pressure water pump.
The heat from the engine and blower exhausts is transferred to the high pressure water
in the nned tube heat exchanger and copper tube and shell of the system. Finally, the
chemical is injected into the pressurized water stream and the heated solution is delivered
to the cleaning tool.
Solution is recovered by the vacuum generated by the vacuum blower and is collected in
the recovery tank for proper disposal.

HydraMaster uses this WARNING symbol throughout the manual to warn of
possible injury or death.
This CAUTION symbol is used to warn of possible equipment damage.
This NOTICe symbol indicates that federal or state regulatory laws may apply,
and also emphasizes supplemental information.
1-5: General Information
Warnings and Cautions specic to the Titan 875 include the following:
During the operation of the truckmount many components are in motion. Never
touch any part of the truckmount that is in motion. Serious injury may result.
During the operation of the truckmount many surfaces will become extremely hot.
Never touch hot surfaces. Serious injury may result.
The operation of this truckmount can produce noise levels exceeding 85 decibels
to a distance of 10 ft. The Occupational Safety and Health Administration (OSHA)
recommends the use of hearing protective equipment if a person is exposed
to an average of 85 decibels over an 8-hour period. Check with local and state
agencies concerning hearing conservation rules.
During the operation of the truckmount carbon monoxide and other toxic fumes
are produced. Position the vehicle so that any fumes produced will be directed
away from inhabited areas and any points of building entry (doors, windows, air
conditioning units, fans, etc.). Do not occupy the vehicle while the truckmount is
in operation. Serious injury may result.
During the operation of the truckmount, chemicals known to the State of California
to cause cancer, birth defects and other reproductive harm are produced by the
engine exhaust.
Never operate the truckmount with a portable gas container inside the vehicle.
Doing so will increase the risk of re and explosion. Serious injury or death may
result.
General Information: 1-6
Transporting a vented fuel container that presently contains, or has ever contained
in the past, a ammable liquid is strictly forbidden by HydraMaster and by federal
and state regulations. Doing so will increase the risk of re and explosion. Serious
injury or death may result.
Never smoke in or around the truckmount. Doing so will increase the risk of re
and explosion. Serious injury or death may result.
During the operation of the truckmount the exhaust system will become extremely
hot. Keep all ammable materials away from the truckmount exhaust system.
Failure to do so will increase the risk of re and explosion. Serious personal injury
and property damage may result.
Never operate the truckmount when the vehicle is tilted more than 10 degrees in
any direction. Doing so will result in improper lubrication of the internal components,
and will increase the risk serious component or engine damage.
Never perform cleaning operations when the truckmount engine is running at the
IDLe throttle position. Failure to do so will increase the risk of serious component
or engine damage.
Never operate the truckmount with the vehicle doors closed. Doing so results in
extremely high temperatures inside the vehicle and will lead to serious component
or engine damage.
Never use concentrated acids or solvents (including d-limonene) in the truckmount
water system or chemical system. Use of these products will cause serious
component damage.
1-7: General Information
Never operate the truckmount with a water hardness reading measuring 3.0
grains per gallon or higher. Using reading than 3.0 grains per gallon will cause
scale to build up inside the truckmount water system. Scale build up causes
serious component damage. Test all water prior to use and use water softening
equipment if necessary.
Never allow water to freeze inside the truckmount. Serious component damage
will occur. Perform all freeze guarding procedures as outlined in Section 4 of this
Owner’s Manual.
Many vehicles have critical components mounted directly below the oor that
can easily be damaged. Before drilling holes in the oor of the vehicle inspect
the underside of the vehicle for critical components. Failure to do so may result
in damage to the vehicle.
Use of the vacuum recovery system when stripping or otherwise removing wax
from oors is specically excluded as an approved use of the truckmount. Failure
to follow this exclusion may lead to component failure and will invalidate your
warranty.
Use of the vacuum recovery system for “dry cleaning”, without corresponding
solution application (i.e. duct cleaning), is specically excluded as an approved
use of the truckmount. Failure to follow this exclusion may lead to component
failure and will invalidate your warranty.
If concentrated acids or solvents are used to pre-treat surfaces before power
washing, do not recover them through the vacuum system. Failure to follow this
exclusion may lead to component failure and will invalidate your warranty.

It is not required to change or adjust the fuel system due to altitude differences. The engine
electronic control system constantly monitors the barometric pressure and fuel mixture in
the exhaust. Using these 2 inputs, the engine can compensate for any elevation. This will
be done each time the engine is turned on.
LOcaL waTeR pRecauTIOns
The quality of water varies greatly. Many areas have an excess of minerals in the water
which results in what is commonly called “hard water.” These minerals tend to adhere to
the insides of heater coils and other parts of the machines causing damage and a loss of
cleaning effectiveness. This inuences the reliability and efciency of equipment in direct
proportion to the level of hardness.
hard water advisory
HydraMaster recognizes that any hard water deposits which might occur within the water
system of our truckmounts is a serious problem. The precision technology of truckmount
heat exchanger systems is intolerant of any foreign material. Hard water deposits will
ultimately decrease the performance of the system and are expected to seriously lower
the reliability of the machine.
To validate a machine’s warranty, HydraMaster requires that all machines operating in
designated “Hard Water Areas” (3.0 grains or more per gallon) be tted with a water
softening system, or a properly installed magnetic-type descaler must be used and
maintained. Periodic descaling or acid-rinsing alone is not adequate in these areas.
HydraMaster does not recommend any particular type or brand; however, the relative
effectiveness of some types of magnetic descalers or softeners may require additional
periodic use of descaling agents.
HydraMaster also recommends, in the strongest possible terms, that machines in all areas
be tted with a water softening system for improved operation and reliability.
Failure to take appropriate measures to prevent scale build up can result in
system failure and loss of warranty on affected parts.
1-15: General Information
hard water area Map
The hard water map, shown in Figure 1-1, denes hard water areas in the continental
United States which compromise uid related components such as hoses, ttings, heaters,
pumps, valves and water-cooled engines. For other countries, hard water area maps can
be obtained from geological societies.
hard water Map of continental united statesFigure 1-1.
The map shown in Figure 1-1 is provided for general reference only. Water
hardness in your geographical location should be conrmed by testing.
General Information: 1-16
water softener
Cleaning efciency and equipment life is increased, chemical use decreased, and the
appearance of cleaned carpets enhanced when water softeners are incorporated in hard
water areas. HydraMaster strongly urges the use of water softener units with the Titan 875
in areas exceeding 3.0 grains per gallon.
Failure to use a water softener in these areas will invalidate the machine’s warranty.
Referring to the hard water area map shown Figure 1-1, determine the quality of water
in your area and take immediate action if the water hardness exceeds 3.0 grains per
gallon.
The relatively low cost of a water softener service is more than made up for by an increased
life of machine parts, reduced chemical costs and continued cleaning efciency. The
water softener will also increase the effectiveness of the cleaning chemicals, therefore
less chemical will be needed.
Contact a water softener distributor in your area for information on the rental of a simple
water treatment unit to carry in your truck. be sure to charge the water softener in
accordance with the capability of the softener.
For example: If the softener will treat 900 gallons of water and the machine uses an
average of 30 gallons/hour, for an average of 5 hours a day, this equals 150 gallons per
day. In 6 days the machine would use 900 gallons of water. Therefore, the softener would
need to be charged every 6 working days for maximum softening.
1-17: General Information
waste water Disposal advisory
There are laws in most communities prohibiting the dumping of recovered “gray” water
from carpet cleaning in any place but a sanitary treatment system.
The cleaning rinse water, recovered into your unit’s vacuum tank, contains materials
such as detergents, and must be safely processed before entering streams, rivers and
reservoirs.
In most cases, an acceptable method of waste water disposal is to discharge into a
municipal sewage treatment system after rst ltering out solid material such as carpet
ber. Access to the sanitary system can be obtained through a toilet, laundry drain, RV
dump, etc. Permission should rst be obtained from any concerned party or agency.
One disposal method which usually complies with the law is to accumulate the waste
water and haul it to an appropriate dump site. Another solution to the disposal problem is
to equip your Titan 875 with an Automatic Pump-Out System (APO). These systems are
designed to remove waste water from the extractor’s recovery system and actively pump
the water through hoses to a suitable disposal drain.
HydraMaster makes an APO System which can be ordered with new equipment or
installed later.
When properly congured, the systems will continuously monitor the level of waste water
and pump it out simultaneously with the cleaning operation. The hidden benet of this
process is that the technician does not have to stop his/her cleaning to empty the recovery
tank.
IN ACCORDANCe WITH ePA, STATe AND LOCAL LAWS, DO NOT DISPOSe OF
WASTe WATeR INTO GUTTeRS, STORM DRAINS, STReAMS, ReSeRVOIRS,
eTC.
The penalties for non-compliance can be serious. Always check local laws and
regulations to be sure you are in compliance.

2 - Installation Information
FueL puMp InsTaLLaTIOn guIDeLInes
general
The 1.6L GM engine on the Titan 875 is fuel injected. This is a high pressure system and
requires approved components and hose to operate within the specications. The average
operating pressure at the fuel rail should be 40 - 50 psi. This pressure is controlled via
an pressure manifold that is placed inline with the fuel pump. The fuel system should be
hooked up in the following order:
Failure to use the specied fuel hose can result in equipment failure or bodily
injury. Fuel hose specication: Fuel injection hose carb no. C-4-06-002 SAE
30R9 180 psi.
Failure to use this hose can result in non-compliance nes set forth by the EPA.
The fuel lter must be on the outlet side of the pump, failure to do so may cause
the engine to run poorly.
It is important that the order of the fuel supply components are installed correctly,
failure to do so may cause the engine or fuel components may not function
properly or be damaged.
All components should be replaced with approved OeM parts.
2-1: Installation Information
The fuel pump has a “domed” end and an end with the electrical terminations. The “domed”
end is the inlet of the pump and the side with the terminations is the output.
The fuel pressure manifold has three ports. The side with the two ports is the return and
the inlet, the side with the single port is the output. The dual port side has one connection
almost in the center of the block; this is the inlet. The connection that is slightly offset is
the return to the fuel tank.
The electrical plug must be positioned at the top when the manifold is installed.
The supplied fuel quick connects are required per the engine certication requirements.
The fuel hose is specic to the Titan 875, this is required by the EPA to maintain the
engine certication as well as the pressure requirements.
Locating components
The Titan 875 is equipped with a fuel pump mounting bracket assembly. This bracket
should be located as close to the fuel source as possible. It should be oriented so the
fuel pressure manifold plug is oriented upwards (see Figure 2-1).
Installation Information: 2-2
Figure 2-1. Fuel pump Diagram
Although there are many different heavy duty vehicles used for carpet cleaning equipment,
the preferable vehicle for a Titan 875 installation is a cargo van with a heavy-duty
suspension package and a 3/4 HD ton capacity. If a fresh water tank is added, a one ton
or larger capacity van is required.
Prior to installing the Titan 875, HydraMaster recommends installing a spray-on bed liner
in the vehicle. This provides ‘metal to cushion’ mounting rather than ‘metal to metal’ and
makes for an attractive van interior.
HydraMaster also recommends installing roof vents in
vehicles operated in hot weather locations. Roof vent
positions are shown in Figure 2-2. Consult your local RV
distributor about selection and/or installation of powered
roof vents.
For best results, the fan should draw air into the vehicle
which will supply cooler air to the air cleaner intake.

Roof Vents in Vehicle
2-3: Installation Information
OpeRaTIng The TITan 875 In hOT weaTheR
HydraMaster recommends the following steps when operating the Titan 875 during periods
of hot weather (95º F or higher). This will help ensure that your Titan 875 continues to run
at 100% capacity during even the hottest days.
A minimum of 9” of clearance is required on both sides of the Titan 875, when
1.
installed. ensure that additional equipment or other materials are not stored at the
sides or on top of the Titan. Unobstructed airow around the unit is critical for cooling
the engine and other components. The covers must be on the machine at all times
to ensure proper cooling.
For side-door vans with “barn doors”, open the doors as wide as their construction
2.
will allow. be sure to open the doors beyond their standard “straight-out” position,
if possible, by releasing the stops and putting the doors in their fully extended
position.
Provide cross-ventilation. When possible, keeping the rear doors open while the
3.
Titan is running will substantially reduce the temperature inside the van and will
provide a path for cooling air ow. For rear-mount installations, open up the other
doors in the van.
Consider adding powered roof vents to the vehicle (if not already installed). These
4.
vents can signicantly reduce interior temperatures and will result in much cooler
operation.
Run the Titan 875 in HOT mode when outdoor temperatures are high. Running the
5.
Titan in WARM mode is not “easier” on the machine. In fact, it cuts the coolant heat
exchanger out of the cleaning solution loop, in effect reducing the engine-cooling
capacity. The Titan was designed to deliver solution at the optimum temperature
to clean carpets when in the HOT mode. The WARM mode is intended for delicate
materials like upholstery.
Installation Information: 2-4
Use caution when drilling any holes through the van oor. Many vans have critical
components mounted directly below the vehicle oor that could be damaged by
a misplaced drill bit.
LOcaTIng The TITan 875 In VehIcLe
There are two recommended entry points on the vehicle for the Titan 875 installation: the
side door or the rear doors.
Most installations are through the side door. This provides rear access for accessories
and hoses as well as unobstructed access to the component/working side of the machine,
thus making it a bit easier to perform maintenance and/or repair without removing the unit
from the truck.
Rear mounting requires the unit to be slid to the right side as far as possible Although
installing the Titan 875 through the rear door partly limits working access, it does direct
the noise away from the cleaning site.
In addition, rear mounting not only provides adequate working space on the component
side of the unit but also improves weight distribution inside the van (engine and component
weight line up over drive shaft). Some cleaners in colder geographical areas prefer this
placement for better traction in ice and snow. Also, it is physically easier to load the unit
into the rear door due to the height of the vehicle bed.
Recommended Location of Titan 875 in VanFigure 2-3.
secure Installation
No matter how the unit is installed, check to see if the Titan 875 is properly secured to
the oor of the van with the hardware provided. This safety measure will ensure that the
machine will not slide inside the van. See Figure 2-3 for the correct installation.
2-5: Installation Information
A sudden or crash stop will cause the machine to rocket forward if not properly
secured. To prevent serious personal injury, ensure that the Titan 875 is well
secured to the oor of the vehicle with the hardware supplied. Protect yourself
and the machine.
HydraMaster strongly recommends that the exhaust from the front of the machine
be vented down under the truck to prevent carbon monoxide from entering the
job site. always park the truck so the exhaust is blowing away from the job site.
Never operate this machine with a portable gas can inside the truck. Doing so
increases the risk of a re or explosion.
Mount a re extinguisher just inside the rear or side door for emergencies.
Do not use a portable propane tank inside of the truck or van. It is dangerous and
illegal in most states.
Transporting any vented fuel container that presently holds or has ever held
a ammable liquid in a vehicle containing the Titan 875 is strictly forbidden by
HydraMaster Corporation and by federal and state regulation.
The engine exhaust from this product contains chemicals known to the State of
California to cause cancer, birth defects or other reproductive harm.
Installation Information: 2-6
seTTIng up The TITan 875
Prior to operating the Titan 875, follow these steps:
Adjust the vacuum relief located on the recovery tank by capping all the vacuum
1.
inlets (the full throttle condition). The machine should be set to 14” Hg maximum.
Setting the vacuum level higher than the recommended value can result in an
increased risk of serious component damage.
The Titan 875 is shipped from the factory with antifreeze added to the solution system.
Recover this antifreeze and dispose of the recovered antifreeze as stated in the local laws
and regulations.
KeeP ANTIFReeZe OUT OF ReACH OF CHILDReN AND ANIMALS. Drinking
antifreeze can cause death.
If required, dispose of antifreeze at facilities licensed to accept household
hazardous waste. If permitted, dispose of antifreeze in sanitary sewer systems.
Do not pour antifreeze into storm sewers, septic systems, or onto the ground.
Doing so causes health and environmental dangers.
ensure the antifreeze is completely drained from the solution system. If any
antifreeze remains in the system, it could damage machine components and
damage fabric.

3 - Cleaning and Chemicals
your HydraMaster truckmount has been engineered using the latest and most sophisticated
technology available to produce the nest carpet cleaning results possible. Despite this,
it remains only a tool of the carpet cleaning trade and can produce only as a good a job
as the person operating it.
hydraMaster strongly recommends attending the clean Trust (formerly known as
as possible and to always follow the clean Trust guidelines when cleaning carpets
and hard surfaces.
This section describes the carpet cleaning procedure in the following areas:

Preparing the Carpet for extractio n
Rinse and Recove r
Over-Wettin g
Streakin g
Cleaning Tool Tip s
Severe Cleaning Situation s
The use of some chemicals (such as concentrated acids and/or solvents) in
your truckmount can seriously damage the internal plumbing and high pressure
pump.
HydraMaster strongly recommends purchasing a water softener system to prevent the
buildup of scale and hard water deposits in your truckmount.
HydraMaster also recommends only the use of chemicals containing rust and corrosion
inhibitors and water softening agents to prevent chemical buildup which may lead to
component failure and warranty invalidation.
3-1: Cleaning and Chemicals
Increased demand for a neutralizing rinse results in the need for special care
when using these acid based chemicals in your truckmount The negative side
of these products is the corrosive effects the acid can have on metals, including
ttings, pumps, heat exchangers, etc.
HydraMaster’s ClearWater Rinse™ has been formulated to protect vital components.
HydraMaster will not warranty parts that have been damaged from using acid products
that have obviously caused failures.
pRepaRIng The caRpeT FOR exTRacTIOn
pre-vacuum the carpet
Whether you instruct the customer to pre-vacuum or you offer it as part of your service,
proper vacuuming will make your job easier with superior end results. The more time
spent removing loose particulate soil, the easier it will be to remove the oily soil stuck to
the bers.
pre-treat the carpet
This process of applying trafc lane type chemicals to the carpet (whether by sprayer or
rotary scrubber) is essential prior to extraction with your truckmount.
by applying cleaning agents to the carpet and letting them dwell 10-20 minutes prior to
rinsing, you allow the product to dissolve and emulsify the oily, sticky binders holding the
soil to the ber. This will allow more soil to be removed in one or two cleaning passes and
help prevent over-wetting.
Remember the solution coming out of your cleaning tool is only in contact with the carpet
ber for a few seconds. Relying on the rinse detergent to do the majority of the cleaning
will result in overly long dry times and excess detergent residue left in the carpet.
HydraMaster recommends the use of our pre-sprays: Fastbreak™ for residential carpet
and Blitz™ for commercial carpet needs.
Cleaning and Chemicals: 3-2
RInse anD RecOVeR
Whether you are using a wand or an RX-20™, you should clean an area approximately
3 ft. x 3 ft. with the solution valve open then immediately go over that area with vacuum
only to remove any excess moisture.
Olen ber is becoming more popular, particularly in commercial installations. The
process mentioned above can leave excessive residual moisture because olen bers
will not absorb any of the cleaning solution. you must only apply solution during the
backward stroke of the wand so it can be immediately captured by the vacuum head.
RX-20™ users should follow each pass with a dry pass. Failure to follow this procedure
will cause solution to ow to the back of the carpet along with some of the soil. This, along
with any soil imbedded in the backing, will be wicked to the surface of the bers as the
carpet dries.
HydraMaster recommends the following rinse aids: Alkaline - Hydra-Dri Powder™ or
Hydra-CleanLiquid™. Acid - Clear Water Rinse™.
OVeRweTTIng
Overwetting is an annoyance to all concerned. extended drying times will leave the
customer with a negative impression of both the cleaning company and the process
used.
There are several factors that will cause over-wetting:
Too few vacuum strokes.
1.
Clogged vacuum blower lter or vacuum tank lid not sealing properly.2.
Vacuum tank drain valve left partially open.3.
Obstructed, cut or kinked vacuum hoses.4.
Obstructed vacuum hoses while cleaning a heavily foam-saturated carpet (it is 5.
recommended to use a crystal type defoamer distributed evenly over the carpet).
sTReakIng
Streaks in the carpet can appear in both clean or dirty areas and normally appear in
heavily soiled, light colored carpets.
Possible reasons of streaking may include:
Clogged or improperly angled spray nozzles.
1.
Spray nozzles that overlap, concentrating the solution.2.
A partially clogged vacuum head.3.
Inconsistent solution temperature.4.
3-3: Cleaning and Chemicals
cLeanIng TOOL TIps
wands
With a wand, keep cleaning strokes short, front to back, and run a “dry pass”.
After pulling the wand for a strip of 3 or 4 ft (0.9 m or 1.2 m) long with the solution trigger
activated, go back up to the top of the stroke, and make a “dry “ pass [i.e. no solution
owing]. This gives the wand a second chance to pick up the solution on the carpet.
If you do not run a dry pass, the carpet can take longer to dry, and, possibly, the pad under
the carpet can become saturated.
be aware of the carpet seams; try to use strokes that are parallel with the seam. Avoid
pulling the want across the seam. every stroke can peel the seam connection and pull

Also, tilt the wand handle down [head up] to move the tool forward, and away from you,
on the carpet. This means less pull on the carpet and less work for you.

Rotary Tool: Rx-20
Rotary tools are easier to move on the carpet, but harder to control at rst. With a rotary
tool, remember to keep strokes short and side-to-side.
before turning on the RX-20, adjust the handle; it should rest right below or even with the
bottom of your pants’ front pockets, with the tool resting at on the oor. Take your time
in adjusting the tool’s height; make sure the head of the tool is at with the oor while you
are holding the handle. Relax your posture; the more difcult it is to hold the tool’s head
at on the oor surface, the more quickly you will tire.
While the tool is running, control the left and right movements of the tool by tilting the head
to the front and back, and lifting the handles up and pushing the handles down. The tool
can be driven to the forward and backward by tilting the head of the unit to the left and
right. The head must be turning to use the self driving feature of the tool, and only requires
a slight bit of pressure to handles to get the head to move the tool across the oor.
As with the wand, drying times will be improved if you run a dry pass between wet passes.
Hold down the solution trigger and move the unit left or right across the oor 3 or 4 ft, then
immediately back across the same pass, without the solution owing, to make the dry
pass. Make the next pass half-overlapping the previous pass.
Use the RX-20 in very heavily trafcked areas or if it has been a long time since the carpet
has been cleaned. beware of the seam edges of carpets and transition edges between
oor surfaces. Use extreme caution when cleaning these areas.
Sometimes it is necessary to use an edge tool or wand to run the perimeter of the room
on in difcult-to-reach areas where the circular head of the rotary units will not reach.

Grip
Part #000-061-144
Use the upholstery tool on small rugs and furniture. When you clean rugs, be sure that the
temperature and chemicals are safe for that particular type of rug.
As with the larger tools, do not leave the surface of the upholstery too wet. Adjust the
volume of water on the tool without it touching any surface: the water should just barely
come out of the tool before the vacuum pulls it back in. The water will only just spray the
top layer of the furniture and the vacuum will pull the dirty water back into the tool.
If you nd it necessary to do a dry pass, keep strokes short to limit the amount of water
that comes into contact with the fabric surface.

When your truckmount is used for hard-surface cleaning or pressure washing, some jobs
may involve severe cleaning situations. In these cases, certain precautions will need to
be taken in order to ensure that the recovery tank and various internal components are
not damaged
The following are examples of severe cleaning situations. (This list is not intended to be
complete.)
Concrete cleaning
•
Concrete stripping•
Parking lot cleaning•
Extremely greasy oors•
Cleaning that results in the recovery of extensive particulate residue•
Cleaning that results in extensive foam production•
When your truckmount is used in severe cleaning situations:
A pre-lter must be used on the vacuum hose. A ne-mesh lter (i.e. nylon) should be
•
installed into the pre-lter. Contact your distributor for more information.
The recovery tank should be inspected and cleaned daily.
•
The recovery tank inlet lter screen should be rinsed after every job.•
The rectangular blower lter should be rinsed after every job.•
Special care should be taken to clean debris from the recovery tank oat switches; •
they should be inspected daily to ensure that they are fully operational.
Any cleaning job that induces excessive foam production should be halted until an
•
approved de-foaming agent can be added to the tank.
Failure to follow these recommendations may lead to component failure and
warranty invalidation.
Use of the vacuum recovery system when stripping or otherwise removing wax
from oors is specically excluded as an approved use of the truckmount. Failure
to follow this exclusion may lead to component failure and will invalidate your
warranty.
3-9: Cleaning and Chemicals
Use of the vacuum recovery system for “dry cleaning”, without corresponding
solution application (i.e. duct cleaning), is specically excluded as an approved
use of the truckmount. Failure to follow this exclusion may lead to component
failure and will invalidate your warranty.
If concentrated acids or solvents are used to pre-treat surfaces before power
washing, do not recover them through the vacuum system. Failure to follow this
exclusion may lead to component failure and will invalidate your warranty.
Cleaning and Chemicals: 3-10
4 - Machine Maintenance
To avoid costly repairs and downtime, it is imperative to develop and practice good
maintenance procedures. These procedures fall into daily, weekly, monthly and quarterly

engine Oil
engine Oil Level Check
The engine oil level should be checked daily. It is recommended that the oil be checked
just before the engine is started for the rst time for that day. The oil level should be
between the ‘Add’ and the ‘Full’ marks on the dipstick.
Do not operate the engine with the oil level below the bottom of the ‘Add’ mark on
the dipstick, or above the top of the ‘Full’ mark.
Adding engine Oil
It is normal to add some oil in the period of time between oil changes. The amount will
vary with the severity of operation. When adding or replacing engine oil, be sure the oil
meets or exceeds the recommended specication.
Changing engine Oil and Filter
The engine oil and lter must be changed every 150 hours or every three months whichever
occurs rst. The oil and lter should be changed more often if the engine is operating in
dusty or extremely dirty areas, or during cold weather.
engine Oil Quality
To achieve proper engine performance and durability, it is important that you use only
engine lubricating oils of the correct quality in you engine. Proper quality oils also provide
maximum efciency for crankcase ventilation systems, which reduces pollution.
Use only engine oils displaying the American Petroleum Institute (API) “starburst”
certication mark ‘FOR GASOLINE ENGINES’ on the container.
engine Oil Recommendation
Multi-viscosity oils are recommended. SAe 10W-30 is recommended for your engine from
0° F or above. If ambient temperatures are consistently below 0° F, SAe 5W-30 oil should
be used. Synthetic oils are not recommended for industrial or stationary engines.
Machine Maintenance: 4-6
Oil Filter
The GM powertrain engines use a AC Delco oil lter as the original equipment. An
equivalent or better oil lter must be used when servicing the engine.
To replace the lter, use a proper lter wrench to remove the lter.
Clean the lter mounting base and lightly coat the gasket surface of the new lter with
engine oil. Hand tighten the lter until the gasket contacts the base, then tighten another
½ turn. Fill the engine with the correct amount of oil, run the engine and check for oil leaks
at the drain plug and oil lter gasket.
spark plugs
Always use the recommended spark plugs for your engine. Hotter or colder plugs, or similar
plugs that are not exact equivalents to the recommended plugs, can cause permanent
engine damage, reduce the engines useful life, and cause many other problems such as
hard starting, spark knock and run-on. Installing new spark plugs regularly is one of the
best ways to keep your engine at peak performance.
air cleaner
Air that contains dirt and grit produces an abrasive fuel mixture and can cause severe
damage to the cylinder walls and piston rings. Damage to the cylinder walls and piston
rings will cause high oil consumption and shorten engine life.
A restricted or dirty air cleaner will also cause a rich fuel mixture. Thus, it is extremely
important that the air cleaner be serviced properly at the recommended intervals.
Service the air cleaner more frequently under severe dusty or dirty conditions.
Failure to do so can result in machine failure.
Remove the primary air cleaner element from the air cleaner assembly and inspect
1.
the element for foreign material restrictions or signs of excessive wear or damage.
Replace the element if necessary.
2.
Remove all dust and foreign matter from the air cleaner housing. 3.
Re-install the air cleaner element. 4.
Re-install the air cleaner cup, and securely fasten the retaining clips.5.
Safety element
If your engine is equipped with an air cleaner which utilizes a safety element, ensure that
the element is properly in place before installing the primary element.
Change the safety element annually.
4-7: Machine Maintenance
cooling system
Coolant Level
Check the coolant level of the radiator daily and only when the engine is cool. Generally
a good time to do this is just prior to starting the engine for the rst time each day.
Maintain the coolant level at 3/4 to 1 1/2” below the ller neck seat of the radiator when
the coolant is cold. Whenever coolant level checks are made, inspect the condition of the
radiator cap rubber seal. Make sure it is clean and free of any dirt particles which would
keep it from seating on the ller neck seat. Rinse off with clean water if necessary. Also
make sure that the ller neck seat is free of any dirt particles.
Never remove the radiator cap under any conditions while the engine is operating.
Failure to follow these instructions could result in damage to the cooling system,
engine, or cause personal injury. To avoid having scalding hot coolant or steam
blowout of the radiator, use extreme caution when removing the radiator cap
from a hot radiator. If possible, wait until the engine has cooled, then wrap a thick
cloth around the radiator cap and turn slowly to the rst stop. Step back while the
pressure is released from the cooling system. When all the pressure has been
released, press down on the cap and remove it slowly.
The engine manufacturer recommends the cooling system be lled with a 50/50
mixture of antifreeze and water. The use of DexCool® “Long Life” or equivalent
type coolant is required. This antifreeze is typically bright orange in color and
should meet requirements issued by the engine supplier. Failure to use this type
of antifreeze may result in corrosion of the cooling system.
DO NOT add coolant to any engine that has become overheated until the engine
cools. Adding coolant to an extremely hot engine can result in a cracked block or
cylinder head.
Machine Maintenance: 4-8
bleeding Air from Cooling System
It is necessary to remove all of the air from the engine to prevent overheating. If the coolant
has been drained for any reason, it will be necessary to follow the bleed procedure.
When the engine is cold, remove the radiator cap.
1.
Fill the radiator until it is to the top of the ller neck. 2.
Start the engine and run in the low rpm position, pump clutch off, and no vacuum 3.
load.
Allow the engine coolant to heat up and open the thermostat several times. As all
4.
the air is removed from the system, the level of the radiator should lower below the
internal tubes.This process should take approximately 5 - 10 minutes.
Top off the coolant and install the cap.
5.
In the event you experience a coolant shutdown due to overheat, allow the machine 6.
to cool down and repeat this procedure.
A kit is available which allows you to add a valve to the radiator to improve bleeding
the air. Ask HydraMaster Technical Support for P/N 000-078-891 Titan Coolant
bleed Valve Kit (INS-33141).
Radiator
Inspect the exterior of the radiator for obstructions. Remove all debris with a soft brush or
cloth. Use care to avoid damaging the core ns.
Fuel Filter
The fuel lter is located between the fuel pump and the fuel pressure manifold underneath
the vehicle. This is a high pressure fuel system and should be replaced with the properly
specied lter.
4-9: Machine Maintenance
hIgh pRessuRe puMp MaInTenance
Daily
Check the oil level and the condition of the oil. The oil
level should be up to the center of the sight glass on
the side or rear of the pump or between the “MIN” and
“MAX” lines on the dipstick. The dipstick may be found
by removing the oil cap.
periodically
Change the oil after the initial 50 hours of operation
and every 500 hours after that. It may be necessary to
replace the pump seals and check valves at 500 hours
if the truckmount has been running in high ambient
temperatures.
If the oil becomes discolored or contaminated one of
the oil seals may be damaged. Do not operate the
pump if the crankcase oil has become contaminated.

VacuuM sysTeM MaInTenance
The vacuum pump in this machine is commonly referred to as a “rotary positive
displacement blower” or “blower” for short. The performance and life of the truckmount is
greatly dependent on the care and proper maintenance it receives. The manual for the
blower has been included. Review the manual for a better understanding of this piece of
machinery.
To protect the blower from overloading and damaging itself, there is a vacuum relief
system installed on the vacuum tank. When the vacuum tank inlet is completely sealed
off, a maximum of 14” Hg will be attained.
Solid objects entering the blower will cause serious damage to the internal
components of the blower. extreme caution should be used when the truckmount is
being run for test purposes with the inlet to the blower open to the atmosphere.
Foam passing through the blower can lead to serious problems with the truckmount.
It is important to keep the vacuum tank free of foam. The tank is protected from
overowing by a oat kill switch; however, this switch is not activated by foam.
Daily
At the end of each day the internal components of the blower need to be lubricated. This
helps to prevent rust deposits and prolongs the life of the truckmount.
To lubricate the blower:
Allow the unit to run for a few minutes with the vacuum hose disconnected in order
1.
to remove moisture from the blower.
Cap off the inlet(s) to the vacuum tank.
2.
Spray a HydraMaster-recommended spray lubricant into the “bLOWeR LUbe 3.
PORT” for about 5 to 10 seconds while the unit is running.
Allow machine to run additional 2 to 5 minutes under load to ush off lubricant.
4.
Uncap the inlet(s) and run the unit for another minute to allow the blower to cool 5.
down.
periodically
Change the oil in both ends of the blower after the initial 100 hours of use. The oil is to be
changed each 500 hours of use thereafter.
4-19: Machine Maintenance
Scale deposits on the interior of the heating system can cause a noticeable loss in heating
performance. Deposits of this kind result from hard water deposits. The frequency with
which descaling procedures are required will vary. If the area has particularly hard water,
you may have to de-scale often.
To de-scale the system, add an appropriate de-scaler chemical to the water box. Circulate
it through the system. Let it stand. Flush and repeat as necessary. Clean all screens and
strainers, and check them frequently following descaling.
If using TM DeScaler™ through the ow meter, make sure to run clean water
through the owmeter after this procedure.
To descale using the recirculation kit (P/N 000-078-058), start with an empty water box.
Fill a third of the water box with TM DeScaler™. Follow the recommendations on the TM
DeScaler™ label for proportions. Verify that the oat is not lying horizontal, but oats
below.
Attach the recirculation tting provided in the kit to the garden hose quick connect (see
Figure 4-19) and this combination to the front of the truckmount.
Attach one section of the solution hose to the outgoing solution tting on the front of the
truckmount and the other end to the garden hose and recirculation tting combination
that is attached to the front of the truckmount. Additional hoses may be attached inline if
descaling of hoses is needed.
Start the truckmount and allow it to run for three to ve minutes. Do not leave the TM
DeScaler™ solution in the system. Flush the system with clean water and turn the
truckmount OFF.

FReeze guaRDIng
To avoid permanent damage to the truckmount it is imperative to follow the Freeze Guard
Procedure whenever the possibility of freezing temperatures exists.
When disposing of antifreeze follow local laws and regulations. Do not discard
into storm sewers, septic systems, or onto the ground.
Antifreeze is harmful or fatal if swallowed. Do not store in open or unlabeled
containers. Keep out of reach of children and animals.
When draining solution from the machine, wear protective eye wear and ensure
the solution temperature is cold. Failure to follow this caution can result in personal
injury.
Freeze guard procedure
With the truckmount turned off and the incoming 1.
water line disconnected, open the water box
drain valve on the front of the truckmount. Allow
the system to fully drain. Close the water box

you can optimize the Titan 875 to the size of the job.
The different scenarios can be dened as follows:
Maximum
1. – Triple wands or rotary machine usage. This means that all available
power is required.
high heat/Reduced Vacuum2. – Dual wand with short hose runs or single wand at
longer hose runs to the job site.
Reduced heat/Full Vacuum3. – Single wand with
short hose runs to the job site.
Low heat/Reduced Vacuum4. – Upholstery or any
reduced solution ow cleaning.

Chemical System
This section describes the water and chemical systems in the following areas:
Water and Chemical Flow Operation
Water and Chemical Flow Diagrams
waTeR anD cheMIcaL FLOw OpeRaTIOn
Fresh water is brought through the front of the truckmount into the water box. The level of
water in the box is maintained by the use of a oat valve. The water is then gravity fed to
the pump where it is pressurized.
Next, the pressurized water enters the bypass valve. This valve allows manual adjustment
of the pressure level. When the valve at the wand is closed, nearly all of the water in the
system is recirculated to the water box at this point. When solution is being used at the
wand the necessary amount of high pressure water passes through the bypass valve and
to the heat exchangers.
In the tube and shell heat exchanger the temperature is raised. The heat necessary to do
this is provided by the engine coolant. The heated water then travels to the blower heat
exchanger. In this nned tube heat exchanger the temperature of the water is raised once
again. The heat necessary to do this is provided by both the engine and blower exhausts.
The heated water nally travels to the high pressure manifold.
The high pressure manifold houses both the temperature sensor for the heat control
system that also acts as a high temperature shutdown switch. There is one orice located
in the manifold. This is referred to as a recirculation orice and allows a small amount
of high pressure, high temperature water to pass back to the water box. This prevents
excessive pressure building up in the heat exchanger when the wand valve is closed and
no solution is exiting the truckmount.
Water that is recirculated through the pressure regulator back to the water box travels
past a low pressure temperature sensor. This sensor monitors the water box temperature.
When the controller senses the water in the water box has reached its set point it opens
the low pressure solenoid on the side of the water box and closes once the temperature
drops back below the set point.
6-1: Water and Chemical System
The water that is being called for by the wand then exits the manifold and passes through
a check valve. Finally, the water joins the chemical where the solution is created.
The chemical is pressurized by the HydraMaster diaphragm chemical pump attached
to the head of the water pump. This pump pulls the chemical from the jug through the
chemical meter. After being pressurized the chemical travels through the metering valve
and is injected into the high pressure stream. This solution then exits the front of the
truckmount and is delivered to the cleaning tool.
