Introduction
CDS 4.8
Section 1-1
6his manual contains operating instructions as well as information required for proper maintenance, adjustment and repair of this unit. Since the first and most
important part of repair work is the correct diagnosis of the problem, component
manual troubleshooting charts have been included for your convenience.
Unlike a garden tractor, lawn mower or cement mixer, all having one or two functions
to perform, the truckmounted carpet cleaning plant has many functions to perform
simultaneously.
 The engine has to run at a consistent RPM.
 The vacuum has to pull air and dirty water back from cleaning site.
 The water pump must provide a stable pressure at proper water
flow for cleaning.
 The chemical has to be injected into the water stream at the right
concentration.
 The heating system must provide a consistant water temperature.
 The vacuum tank must store dirty water until drained.
As you can see, it is not just a turn-key operation with one thing to worry about, Does
it start?!

Precautions
)though this unit has been factory adjusted, it may require additional adjustments to achieve optimum performance, for instance altitude may require carburetor
adjustment and ambient temperatures may require heat control adjustment. When
required, consult an authorized representative.
THROUGH-FLOOR DRILLING: Be cautious when drilling holes through the van floor.
Many vans have critical components mounted directly below the van floor that could
be damaged by a misplaced drill bit. (See Product Support Bulletins 921 2, 94 62
and 94 63 at the end of the manual.)
LEVEL OPERATION: During operation, van or trailer must be parked on level ground
not to exceed + or - 1 degrees. Failure to insure proper leveling may prevent proper
internal lubrication of engine, vacuum and/or high pressure components.
MOVING PART : Never touch any part of the machine that is in motion. Severe
bodily injury may result.

ACID RIN E AGENT : The increased demand for clear water rinsing results in the
need for special care when using these acid based chemicals in your equipment. The
negative side of these products is the corrosive effects the acid can have on metals,
including swivels, 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 unprotected
acid products that have obviously caused failures.
HARD WATER PROTECTION: Failure to take appropriate measures to prevent scale
build up can result in system failure and loss of warranty on affected parts. Test the
water in your immediate and surrounding areas with hard water test strips. Assume
all water obtained from wells is hard. If you are operating in a AHard Water Area@
(3.5 grains or more per gallon), use a water softening system.
FREEZE PROTECTION: There is often little warning before a cold spell. Therefore,
not protecting this equipment from freezing will result in costly down-time. Placing
an electric heater in the truck or parking the truck indoors will help to insure against
freezing, but should not be the primary method of freeze protection.
HOT URFACE : During the operation of this equipment, many surfaces on the
machine will become very hot. When near the van for any reason care must be taken
not to touch any hot surface, such as heater, engine, exhaust, etc.
