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 Environ- mental 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

>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-

(a)Adjust handle to its extreme upright position (Note: Pins should be in the hole marked "TILTBACK").

(b)Grabbing the handle with both hands and placing your foot on the back deck of the burnisher for stability, pull back on the handle and tilt the machine back.

(c)Let the handle rest on the floor to hold the machine in the upright position.

(d)Now move to the pad side of the machine.

(e)Grab the metal clip, which is located in the white center-lock device, between the thumb and index finger and squeeze. This allows the pad retainer to "pop" off.

(f)Remove the old pad.

(g)Install the new pad by carefully centering it against the "harpoon hook" plastic gripper.

(h)Replace the pad retainer by snapping it back in place (Note: The center-lock ring should "snap" twice).

(i)Check the rotation of the pad driver. Eccentric- ity of the pad should not exceed 1/4 of an inch.

3.Belt Replacement -

(a)Tilt the machine back as you would to replace the pad.

(b)Using a 3/4" open-end wrench, secure the shaft from the engine side of the deck and spin off the pad driver to remove it.

(c)Use the same 3/4" wrench to release tension on the belt by rotating the Lovejoy tensioner towards the belt.

(d)Release the Lovejoy tensioner and carefully remove the belt from the engine clutch and the drive pulley.

(e)Now install the new belt onto the clutch and pulley and use the wrench to again release the tension on the Lovejoy tensioner until the belt is in position.

(f)Release the Lovejoy tensioner to apply tension to the belt. (Note: the arrow on the Lovejoy tensioner should be pointing towards 30°. If it is not, reset the tensioner by first loosening and then re-tightening the bolt that holds the tensioner to the deck).

(g)Reinstall the pad driver.

4.Changing the Engine Oil -

(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 filter wrench, rotate the oil filter counterclockwise. Note: Before unscrewing the oil filter, place a suitable container beneath the oil drip tray to catch the oil that is from the filter or any oil passages in the engine.

(b)Clean the oil filter base on the engine.
