WARNING! Follow the instructions given in this book-
let, the Engines Owners Manual and the training given
by your supervisor for the safe operation of this ma-
chine. Failure to do so can result in personal injury and/
or damage to the machine or property.
DO NOT OPERATE THIS MACHINE IN AN
EXPLOSIVE ENVIRONMENT!
The NightHawk Propane Burnishers are intended for
commercial use.
A. CHECK THE ENGINE OIL BEFORE EVERY
OPERATION!
Make sure the machine is level when checking the oil.
Always take 2 readings of the dip stick before adding
oil. If the oil level is below the full mark, add just
enough oil to the engine to bring the oil level up to the
full mark. Never over fill. Follow the guidelines in
your Engine Owners Manual. Check for foreign ma-
terial on the dipstick.
B. PROPERLY FILL AND CHECK YOUR LP TANK
AND ALL LP FUEL LINES FOR LEAKS!
1. Every tank we sell has been pressure and leak
tested. However, every time a tank is filled and/or
connected to the machine it should be soap tested.
All LP lines must be pressurized and every inch of
line and connections must be sprayed. If you find a
leak, make the proper repairs before operating the
machine. NOTE: The connection and disconnection
of the LP tank must be done in a well ventilated area
with NO source of ignition within 10 feet (3 meters)
from the point of connection.
2. Never over fill the LP tank. Your buffer's LP
tank is designed to hold just 20 pounds of propane.
Make sure to weigh the tank as it is being filled.
The gross weight of a full tank should not exceed 48
pounds. If while operating the machine you notice
frost forming on the LP lines or the regulator, your
tank has been over filled. If you continue to operate
the machine in this condition damage will occur.
The excess propane in the tank must be removed
before normal operations resume. The bleeding of a
propane tank should be done in a safe location
outside the building. In some cases the regulator
must defrost befor restarting the engine.
OPERATING PROCEDURES
C. CONNECTING THE HIGH PRESSURE HOSE
TO THE LP TANK: Make sure the couplers are in
line and screwed together hand tight (see page 13). If
this is not done properly, fuel will not pass through to
the regulator.
D. INSTALL A FRESH PAD BEFORE EVERY JOB;
if not new, at least clean. To install a fresh pad, set the
machine down in the rear. Unscrew and remove the
yellow pad-centering ring. See page 9, the "Pad
Driver Assembly". Remove the old pad and center
the new pad onto the pad driver. Reinstall the yellow
pad-centering ring. Never "flip" a pad. Keep the same
side down throughout the life of the pad. Even after a
pad is cleaned, you can tell the down side by the cen-
tering ring indentation. This practice will increase
the pad life and help maintain a properly functioning
pad driver. NEVER TILT A MACHINE ON ITS
SIDE!
E. STARTING THE HONDA ENGINE.
1. Make sure you have completed items A,B,C and
D above. Also make sure the fuel is on at the
tank. Set the machine down in the rear. If your
unit is equipped with a centrifugal clutch, set down
is not necessary.
2. Push the throttle lever all the way forward to en-
gage the choke (see page 11).
3. Plug the starter cord into a 115-volt outlet (page
14).
4. Push the starter button.
5. When the engine starts, release the starter button
and adjust the throttle back to a high idle. Un-
plug the cord.
6. Lower the buffing deck to the floor and set the
throttle to the desired buffing speed. Always keep
the machine moving while the pad is touching
the floor.
7. Keep hands, fingers and feet clear of all moving
parts while the machine is in operation.
