Introduction
Congratulations on your selection of the CARBONCLEAN SYSTEM II. By choosing this product, you
are acquiring the most technologically advanced method available for cleaning harmful fuel system
contaminants from gasoline engines.
The
LE-1 is a self-contained cleaning system, designed to connect to any gasoline engine. Once the unit
is connected, it temporarily replaces the regular fuel supply with a mixture of gasoline and the specially
formulated
With the engine idling, the unit pumps the gasoline/detergent mixture through the engine's fuel system.
As the mixture passes through the vehicles’ fuel system, it loosens and dissolves accumulated deposits,
which then pass harmlessly out through the exhaust system or are removed by the unit fuel filter.
Removing contaminants from the combustion chamber creates a more even burn of fuel, which improves
horsepower, increases fuel economy, and reduces exhaust emissions.
It is recommended that you perform the fuel system cleaning procedure on a vehicle every 12,000 to
16,000 kilometers to obtain the highest fuel system efficiency.
Please study this User Guide to become thoroughly familiar with the
CarbonClean Cleaning Detergent for Gasoline.
LE-1 before using it.
IMPORTANT
The LE-1 Fuel System Cleaner is designed to work
EXCLUSIVELY
with the CarbonClean Cleaning Detergents for Gasoline.
Use of any other chemical during this process may cause operational failure of
the LE-1 and voids the manufacturer’s warranty.
See warranty card for details.

Overview
Safety Information and Precautions
/!\ DANGER
Vehicle exhaust gases contain Carbon Monoxide, which is a colorless and odorless lethal gas.
Only run engines in well-ventilated areas and avoid breathing exhaust gases.
Extended breathing of exhaust gases will cause serious injury or death.
/!\ WARNING
Exhaust gases, moving parts, hot surfaces, and potent chemicals are present during the use of the fuel
system cleaner.
Read and understand the operator’s manual before using the fuel system cleaner.
When using chemicals always refer to the MSDS sheets and manufacturer’s instructions for the
proper procedure to handle emergency medical treatment, cleanup, handling, and storage
requirements.
Improper use of the fuel system cleaner or exposure to exhaust gases or cleaning chemicals can cause
injury.
Flammable fuel chemical and vapors can ignite.
Avoid exposure to flames, sparks, hot engine parts, and other ignition sources.
Always keep fully charge fire extinguisher nearby. The extinguisher should have a class B rating
and be suitable for gasoline, chemical, and electrical fires.
Cleanup any fuel or chemical spills immediately.
Dispose of contaminated cleanup material according to governing environmental laws.
Never look directly into the air induction plenum or carburetor throat when the engine is
operating.
Always plug or cap any open fuel lines during service.
Keep Cleaner and Detergent container closed except when filling reservoir.
Explosion or flame or exposure to flammable liquid and vapors can cause injury.
Flammable liquid can splash out of reservoir when pump is on and/or unit is being moved.
Always keep Reservoir Cap secure except when filling reservoir.
Explosion or flame can cause injury.
Many fuel systems maintain residual pressure in fuel lines even after the engine has been turned off.
Wear safety goggles.
Wear chemical resistant gloves when connecting or disconnecting fitting and adaptors.
Obtain ZERO psi before connecting or disconnecting any fuel lines or adaptors.
Explosion or flame or exposure to flammable liquid and vapors can cause injury.

Overview
Chemicals can cause harmful byproducts.
Use only approved chemicals (refer to operator’s manual).
Do not swallow or ingest any chemicals.
Use with adequate ventilation. Avoid breathing vapors.
Do not store chemicals on the machine.
Improper use of chemicals can cause injury.
Over exposure can have harmful effect on eyes, skin, respiratory system and possible unconsciousness
and asphyxiation.
Improperly blocked vehicles can move.
Set the parking brake and chock the wheels.
Moving vehicles can cause injury.
Moving engine parts.
The engine cooling fan will cycle on and off depending on the coolant temperature and could operate
without the engine running.
Wear safety goggles.
Always keep objects, clothing, and hands away from the cooling fans and engine parts.
Moving engine parts can cause injury.
Hot surfaces are present during and after running the engine.
Do not contact hot surfaces such as, manifolds, pipes, mufflers, catalytic converters, or radiators
and hoses.
Hot surfaces can cause injury.
Catalytic converters become extremely hot.
Do not park a converter-equipped vehicle over dry grass, leaves, paper, or any other flammable
material.
Do not touch a catalytic converter until the engine has been off for at least 45 minutes.
For tests allowing unburned hydrocarbons or service involving operation of an overly rich
condition, minimize the time of rich operation, monitor the catalytic converter temperature, and
allow at least two minutes of operation at normal mixture subsequent to testing or service for
converter cooling.
Catalytic converters can cause burns.
Cracked fan blade can become airborne.
Examine fan blades for cracks. If found, do not service the vehicle.
Flying objects can cause injury.
Batteries produce explosive gases and can explode.
Wear safety goggles when working on or near batteries.
Use in a well-ventilated area.
Keep sparks and flames away from the battery and never lay tools, equipment, or other
conductive objects on the battery.

Overview
Before You Begin
First Time Operation
NOTE
The following process is used to flush factory
testing fluids out of your new machine, and is
only necessary before the first time you use the
unit.
1. Verify that the LE-1’s fuel filter is connected and securely in place in the rear of the cabinet.
2. Check the output/return hoses, battery connections, and all external components for damage.
3. Turn the Pressure Adjust regulator on the unit control panel counterclockwise until it is
completely open.
4. Attach the unit to the vehicle's battery by connecting the red battery clip to the positive (+)
battery terminal and the black battery clip to a solid ground point as far from the battery as
possible. Turn on the LE-1 power switch.
5. Fill the LE-1’s reservoir with clean gasoline
6. Connect the LE-1’s output (red) hose and return (black) hose together by using the
#060-1400 adaptors and securing them with a clamp. Follow the procedures below to flush fuel
through the system:
• Set the Timer knob for five minutes.
• Press and hold the Start/Run switch for five minutes.
• Release the Start/Run switch.
7. Disconnect the output and return lines.
8. Connect the #060-1400 adaptor to the output hose, then drain the gasoline from the LE-1’s
reservoir using the following procedure:
• Set the Timer knob for five minutes.
• Direct the output (red) hose into an appropriate container.
• Press and hold the Start/Run switch until the fuel from the unit has been emptied into the
container.
1998 MotorVac Technologies, xi
until the tank level indicates 1/4 tank.
Overview
• Release the Start/Run switch.
• Dispose of the fuel in an environmentally approved method.
9. The LE-1’s reservoir is now completely drained of fuel. Follow the steps below before
performing the first cleaning service:
Mixing Ratios
Using a separate container or the LE-1’s reservoir, follow the chart below to mix the proper amounts of
CarbonClean Cleaning Detergent for Gasoline and fuel for the cleaning process.
NOTE
The proper ratio is 1 oz. (30 ml.) per cylinder to 3 oz. (90 ml.) gasoline.
DETERGENT / GASOLINE RATIO
3 cylinders = 3 oz. (90 ml.) detergent to 9 oz. (270 ml.) gasoline, (360 TOTAL)
4 cylinders = 4 oz. (120 ml.) detergent to 12 oz. (360 ml.) gasoline, (480 TOTAL)
5 cylinders = 5 oz. (150 ml.) detergent to 15 oz. (450 ml.) gasoline, (600 TOTAL)
6 cylinders = 6 oz. (180 ml.) detergent to 18 oz. (540 ml.) gasoline, (720 TOTAL)
8 cylinders = 8 oz. (240 ml.) detergent to 24 oz. (720 ml.) gasoline, (960 TOTAL)
