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
1. 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.
2. 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.
3.
Belt replacement.
Tilt the machine on its side (observing the following precautions) and block securely.
**KAWASAKI and HONDA single cylinder - Do not turn the carburetor side down . Oil will enter the intake manifold
and may cause engine damage. Turn the machines with the exhaust side down.
**KAWASAKI twin cylinder. Do not tilt the machine on its nose as this is where the carburetor is located. It is okay to
turn this model on either its left or right side.
(a) Remove pad.
(b) Use a suitable wrench to secure the top of the shaft and spin off the pad driver.
(c) Remove old belt carefully and completely.
(d) Install new belt and adjust the pressure of the tensioner
(e) Reinstall pad driver.
