v: Boxxer 318 Owner’s Manual
1- General Information
The Boxxer™ 318 is a carefully engineered truckmount designed by HydraMaster
Corporation.
The system utilizes an internal combustion
engine to provide the power necessary to
turn both a blower (also referred to as a
vacuum pump) and a high pressure water
pump.
The heat of the engine and blower
exhausts is transferred to the high
pressure water in the nned tube heat
exchanger of the system.
Finally, the chemical is injected into the
pressurized water stream and the heated
solution is delivered to the cleaning tool.
The solution is recovered by the vacuum generated by the blower and is collected in the
recovery tank for proper disposal.
It is the purpose of this manual to help the technician properly understand, maintain and
service the truckmount. By following these guidelines carefully, you can expect years of
reliable operation.

elevation plays a key role in how the truckmount will operate. Operation at high altitude
(above 5,000 ft.) may require a high-altitude carburetor jet. use of this jet at high altitude
will improve power, reduce fuel consumption and help reduce excessive carbon build-up
in the exhaust and heat exchanger systems.
Contact the local Briggs and Stratton dealer or HydraMaster to obtain the proper jet
size. your local Briggs and Stratton dealer can be located at http://vanguardengines.via.

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.
General Information: 1-12
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 Mainland 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.
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
Boxxer 318 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.
1-13: General Information
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.
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 Boxxer 318 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.
General Information: 1-14
2 - 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 an Institute of Inspection, Cleaning
and Restoration Certication (IICRC) approved school as soon as possible and to
always follow the IICrC guidelines when cleaning.
This section describes the carpet cleaning procedure in the following areas:
Precautions
Preparing the Carpet for extraction
Rinse and Recover
Overwetting
Streaking
PrECaUtIOnS
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 to prevent the buildup of
scale and hard water deposits in your truckmount.
HydraMaster 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.
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.
2-1: Chemicals and Cleaning
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.
Pretreat 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.

Whether you are using a wand, RDM™ 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™ and RDM™ 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.

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 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
the carpet off the oor.
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.

Upholstery tool: DriMaster
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.
