EMISSION CONTROL INFORMATION
To protect the environment in which we will live, the manufacturer has incorporated (1) crankcase emission and
(2) exhaust emission control systems (EM) in compliance with applicable regulations of the United States
Environmental Protection Agency and California Air Resources Board.
1. Crankcase Emission Control System. A sealed-type crankcase emission control system is used to
eliminate blow-by gases. The blow-by gases are led to the breather chamber through the crankcase.
Then, it is led to the air cleaner. Oil is separated from the gases while passing through the inside of the
breather chamber from the crankcase, and then returned back to the bottom of crankcase.
2. Exhaust Emission Control System. The exhaust emission control system applied to this engine consists of
a carburetor and an ignition system having optimum ignition timing characteristics. The carburetor has
been calibrated to provide lean air/fuel mixture characteristics and optimum fuel economy with a suitable
air cleaner and exhaust system.
Tampering with Emission Control System Prohibited: Federal law and California State law prohibits the
following acts or the causing thereof: (1) the removal or rendering inoperative by any person other than far
purposes of maintenance, repair, or replacement, of any device or element at design incorporated into any new
engine for the purpose of emission control prior to its sale or delivery to the ultimate purchaser or while it is in use,
or (2) the use of the engine after such device or element of design has been removed or rendered inoperative by
any person.
Among those acts presumed to constitute tampering involve the parts/systems listed below:
• Carburetor and internal parts
• Spark plugs
• Magneto or electronic ignition system
• Fuel filter element
• Air cleaner elements
• Crankcase
• Cylinder heads
• Breather chamber and internal parts
• Intake pipe and tube
GENERAL MAINTENANCE AND ADJUSTMENTS
FUEL CONTROL SYSTEM
To ensure personal safety, adjustments should ONLY be made by a qualified LPG system technician or an
authorized service center, using an exhaust gas analyzer. Do not operate the machine if carbon monoxide levels
exceed OSHA standards.
PAD REPLACEMENT
Tilt the machine back on its rear caster to reach the pad centering device. Turn the outer ring counterclockwise to
remove it. Remove the old pad. Install the new pad by carefully centering it against the "harpoon hook" plastic
gripper. Replace the center locking ring. Check rotation of the pad driver. Eccentricity of the pad should not
exceed 1/4 of an inch.
