MAINTENANCE AND ADJUSTMENTS

Emission Control Information

To protect the environment in which we will live, the manufacturer has incorporated crankcase emission (1) and exhaust emission (2) 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 w/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 for
purposes of maintenance, repair, or replacement, of any device or element of 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 are the acts listed below:
Do not tamper with the original emission related part.
>Carburetor and internal parts
>Spark plugs (Only OEM quality and part number spark plugs may be used to replace the OEM spark plug the machine was equipped with from the factory)
>Magneto or electronic ignition system
>Air cleaner elements (Only OEM quality and part number air fi lters may be used to replace the OEM air fi lter the machine was equipped with from the factory)
>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 qualifi ed 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.
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 and remove it from the machine.
(c) Remove old belt carefully and completely.
(d) Install new belt and adjust the pressure of the Automatic tensioner.
(e) Reinstall pad driver.
4. Changing the Engine Oil -
WARNING!
Changing the oil to a non OEM approved viscosity may change the emission output of the engine!
(a) Start and warm up the engine so the oil will drain easily.
(b) Stop the engine.
(c) Place the buffer in a level position.
(d) Pull the clear plastic tube out of it's holder and rotate the tube so that it can drain into a container.
(e) Grab the 1/4-turn quick release oil drain and rotate counterclockwise. This will allow the engine oil to drain.
(f) After draining is complete, rotate the quick release 1/4-turn clockwise to close and store the clear plastic tube in it's upright position.
5. Changing the Oil Filter -
(a) Using either a strap wrench or an oil fi lter wrench, rotate the oil fi lter counterclockwise. Note: Before unscrewing the oil fi lter, place a suitable container beneath the oil
drip tray to catch the oil that is from the fi lter or any oil passages in the engine.
(b) Clean the oil fi lter base on the engine.
(c) Apply a thin coat of engine oil to the seal of the oil fi lter.
(d) Install the fi lter by turning it clockwise until the seal contacts the mounting surface of the engine.
(e) Then turn the fi lter by hand(s) 3/4 turn more.
(f) Run the engine at a slow idle speed for 2 minutes and check the oil fi lter and drain line for leaks.
6. Adjusting Pad Pressure -
(a) Tilt the machine on its side (observing the following precautions) and block securely.
(b) To increase the pad pressure, move the wheels towards the rear of the machine. To do this, remove the nut. Slide the bolt out and move the wheel to the back hole in the
wheel caster. Reinsert the bolt and reinstall the nut.
(c) To decrease pad pressure, use the same procedure and move the wheel towards the front of the machine.
