his manual contains installation and operation instructions as well as informa-
tion 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 func-
tions 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 provides 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 maintain proper heat.
• 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?!
