How to Operate the Machine

Preparing The Machine For Use
BEFORE using any type of powered equipment, proper safety
dictates you should visually inspect it.
1. Adjust the HANDLE to a comfortable height and tighten the
bolts to 30-50- ft/lbs.
2. BONNET FILTER - Make sure the bonnet air filter atop the
engine is clean. It should be changed hourly and thoroughly
cleaned before reuse.
3. Check the engine OIL LEVEL. Make sure the machine is in a
level position.
**KAWASAKI - DO NOT screw the dipstick in to get reading.
4. Fill the tank following the instructions as given under the
previous heading: "Refilling And Storing Propane Tanks." In
addition, if your buffer came with an "80% Safety Fill Tank"
then it should ONLY be filled through the threaded valve with
the larger diameter that is covered by a yellow cap to ensure
a "Full" level that is safe.
5. PAD AND PAD HOLDER - Inspect the condition of the pad and
pad holder. Is there a pad? Is it properly attached? What is its
condition? Ensure the pad is clean and has at least a
thickness of 1/3 inch. ALWAYS turn off the engine to clean or
replace pad.
6. TANK and FUEL LINES - The tank has already been covered
but do the fuel lines show any sign of wear and tear, such as
cracks or any corrosion? Screw the brass fuel line fitting onto
the tank service valve hand tight only. This connection MUST
be secure because the service valve has a safety valve inside
it which will only open if the brass fuel line fitting is COM-
PLETELY seated into the service valve.
Starting the Engine
1. Plug in 110 volt starter cord on models so equipped.
2.**KAWASAKI - The KAWASAKI twin cylinder engines are
designed to be started in the IDLE throttle position. This
creates a vacuum necessary to open the lock-off valve inside
the regulator. Actuation of the throttle lever will keep the lock-
off valve from opening and the engine from getting fuel so the
engine will not start. Proper maintenance will insure easy
starting.
3. Open (counterclockwise) the service valve on the propane
tank about one and a half turns.
4. Ensure the buffer is tilted back so that the pad is off the floor
on all machines without a clutch.
5. Engage starter for a MAXIMUM of 5 to 6 seconds or until the
engine fires. Serious starter damage will result if this is
exceeded and the warranty may not apply.
6. Operate the engine at half throttle for approximately two
minutes for proper warm-up. Then advance to full throttle for
best results.
NOTE: If the engine refuses to start, see the Trouble Shooting Guide.
Stopping The Engine
1. Close (clockwise) the service valve on the propane tank.
2. ALWAYS allow the engine to run until it stops from lack of fuel
and then turn off the key switch. ** ONLY IN AN EMER-
GENCY should the "kill switch" be used.
3. Disconnect the fuel line from the tank.
4. REMEMBER, when you are finished with the machine, store
the propane tank outside the building, in a safe place away
from heat or direct sunlight.

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.
Crankcase Emission Control System. A sealed-type
1.
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. 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.
