zIn rooms and areas without proper ventilation.
Refueling and Storage of Fuel Cylinders
This machine uses a 20lb (9.1kg) capacity aluminum or
steel cylinder, which meets the DOT 4E240 standards.
These cylinders are also listed by UL. In addition, the
steel cylinder meets European TPED specifications and is
CE compliant. Filling should be done ONLY by a qualified
propane dealer. FILL THROUGH THE SERVICE VALVE
ONLY. A properly filled cylinder should not exceed 80% of
the rated capacity.
DO NOT attempt cylinder repair. Return the cylinder to your
propane dealer if repair is necessary. Please note that DOT
regulations prohibit shipping of cylinders after the cylinder
has been filled with propane.
When not in use, cylinders should always be stored
outside in an upright position in a secure, tamper-proof,
steel mesh storage cabinet. The cabinet may be located
next to the building, but with at least five feet (1.5 m) of
space between the cabinet and the nearest building
opening (door or window).
The cylinder to be used on this machine is a vapor
withdraw cylinder. A liquid withdraw cylinder is not to
be used with this machine. The use of a liquid withdraw
cylinder on a vapor withdraw system could freeze the
regulator and create a fire hazard. The National Fire
Protection Association (NFPA) Standard for Storage and

Test for Operator-Ear Sound Pressure Level
Amano Pioneer Eclipse measures and rates the operator-
ear sound pressure level for hand-guided floor treatment
and floor cleaning machines for industrial use. All tests are
performed in accordance with European Machinery
Directive (2006/42/EC).
zOutdoor test area consists of a flat open space
free from effects of signboards, buildings or
hillsides for at least 15 m (50 ft) from the center of
the test surface. Indoor tests are conducted in a
semi-anechoic or sound deadening room.
zThe test surface is a single sheet of floor covering
at least 1 m (3.3 ft) wider and longer than the
equipment being tested. In order to not affect the
sound reading, the observer taking readings is at
least 2 m (6.6 ft.) from the equipment being tested,
or standing directly behind the operator.
zAll machines are tested while stationary and
centered on the test surface. With the traction
drive in neutral (where applicable) the test is
conducted with the machine at maximum engine
or motor speed as specified by the manufacturer.
zThe operator is located in the normal operating
position with the microphone or meter supported
independent of the machine, 1,68 m (66 in) above
the test surface, 25 cm (10 in) to the right and left
centerline of the operators position, and 20 cm
(8 in) to the rearmost point of the handle, with the
handle in the most forward position.
zThe sound level meter is observed for a minimum
of 5 seconds or until a stabilized reading is
obtained. The maximum repeatable sound level
observed during the test at each microphone
position is recorded and documented.
Test for Hand-Arm Vibration at the Grip
Surface of Hand-Guided Machinery
Amano Pioneer Eclipse measures and rates the vibration at
the machine-hand contact surface of hand-guided
machines that are provided with handles in accordance
with European Machinery Directive (2006/42/EC).
zThe test area consists of a flat open floor area

Filling the LP Cylinder
This machine uses the 20 lb (9.1 kg) capacity cylinder,
which meets the D.O.T. 4E240 standards. These cylinders
are also listed by UL. In addition, the steel cylinder meets
European TPED specifications and is CE compliant. Filling
should be done ONLY by a qualified propane dealer. A
properly filled cylinder should not exceed 80% of the rated
capacity. DO NOT overfill the cylinder or use a liquid
withdraw cylinder on the machine. The use of a liquid
withdraw cylinder on a vapor withdraw system could freeze
the regulator and create a fire hazard.
Installing the LP Cylinder
Place the Safe-Fill® cylinder on the cylinder platform at
the back of the machine. Connect the fuel hose coupling
to the service valve by turning to the right (clockwise).
HAND TIGHTEN ONLY! Make sure coupling is not cross
threaded and check for leakage by noting any propane
odors immediately after cylinder is connected. Finally,
secure the tank to the machine using the adjustable strap.

Engine Ignition Switch
This machine features a key switch ignition.
Start: Turn the key all the way clockwise or START to
engage the engine starter motor. Once the engine starts
release the key.
Note: Always start this machine with the throttle in the idle
or “slow” position.
Run: This is the position of the key while the engine is
running.
Off: Turn the key to the “OFF” position to stop the engine
from running.
Note: For safety, always close the propane cylinder valve
to stop the engine and then turn the key switch to the “OFF”
position.
Engine Throttle
The engine throttle controls the engine speed. To increase
engine speed, move the hand lever forward. For idle
position, pull the lever back.
EcoSense Emissions Monitoring System
All units are equipped with an EcoSense Emissions
Monitoring System. EcoSense is an emissions monitoring
device that monitors the exhaust emissions and will shut
the engine down if the emissions levels are too low or too
high.
Why will the unit shut down if the levels are too low? The
monitor must receive a signal from the oxygen sensor in
order to function. If it did not have a minimum reading
requirement it would be possible to disconnect the oxygen
sensor and operate the unit, even if the emissions were
out of limits. In order for the unit to work as designed it
must be able to read both low and high signals, with “not to
exceed limits” of both.
The oxygen sensor must reach operating temperature
before it will start to send signals to the EcoSense module.
This time is set at one minute. A unit may shut down at a
cold start up after one minute because the oxygen sensor
did not reach required temperature to start to send signals.
If this happens, turn the key to the off position several
seconds to clear the EcoSense module and restart the
engine. Once the engine has started, advance the throttle
to full throttle position and start the operation. With the
engine at full throttle under load, the signal from the
oxygen sensor should be within the normal operating
ranges for safe operation. If the engine’s air intake filter
needs to be serviced, or an over-filled cylinder has been
installed by mistake, or there is a problem with the fuel
system that causes the oxygen sensor’s signal to be out of
range, EcoSense will shut the unit down in four minutes.
The unit can be re-started after clearing the module by
turning off the key switch. If corrections have not been
made to the unit, EcoSense will continue to shut the unit
down after the one minute warm-up and/or four minute out
of limit periods.
Engines tend to go to lean burn if allowed to idle for even
short periods. Even at high idle speeds most engines will
continue to lean downward. It is always best to shut the
engine off when it is not being used to do work.
Remember the engine is always creating emissions as long
as it is running.
The best manner to operate a unit equipped with EcoSense
is as follows.
1. With the throttle in the “slow” or idle position, turn the
key switch to the start position. Once the engine starts,
advance the throttle to the “fast” or full throttle position.
2. When ready to stop operation, release the safety bail
and move the throttle to the idle position. If the unit will
not be used within one minute, turn the key switch to
the off position. If the unit will not be returned to service
within a few minutes it is best to turn the gas valve on
the tank off first and let the engine consume all fuel that
is in lines. Once the engine dies, turn the key switch to
off position.
3. When ready to restart, open the gas valve on the tank,
put the throttle in slow position and turn key switch to
the start position. Once the engine has started, move
throttle to full position and return to operation.

displays hours when the machine is turned OFF and engine
speed when the machine is turned ON. A chart is located
on the control panel that indicates the head speed at
various engine speeds.
Deck Switch
The deck switch energizes the clutch, allowing the heads to
turn when the safety bail is engaged.
Engage: Press the top of the switch. The green light is
ON.
Disengage: Press the bottom of the switch. The green
light is OFF.
Note: The safety bail must be pulled back for the clutch to
engage.
Safety Bail
The safety bail must be pulled back in order for the clutch
to be engaged and the deck heads to rotate.
Engage: Press the top of the deck switch and pull the
safety bail back.
Disengage: Release the safety bail and press the bottom
of the deck switch.
Solution Control
The solution control cable controls the solution flow to the
floor.
Increase Flow: Pull the knob outward.
Decrease Flow: Push the knob inward.
Stop: Push the button all the way in.
Note: Even if the key switch is in the “OFF” position,
solution can still be dispensed on the floor. Take care to
push the knob in when the machine is not in use.
Handle Adjustment / Position

12. Verify that all three lugs of both head assemblies
are correctly installed. If all three lugs are not
properly installed, it is possible that the assembly
could come loose from the machine. This may also
cause damage to the machine and/or floor. (Note:
In a grinding or polishing application it is very
important that all three lugs of each head are
correct. If a lug is out of place, the head could
cause uneven diamond wear and/or damage the
floor.)
13. This machine is compatible with pad drivers,
brushes, and other various type heads. Consult
the “Machine Options” section of this manual for
more information.
Fuses
The machine’s electrical circuit is protected by two fuses,
which stops the flow of current in the event of a circuit
overload. Once a fuse blows, it must be replaced. If the
overload that caused the fuse to fail is still present, the new
fuse will fail and the problem must be corrected. DO NOT
bypass any fuse.
Solution Tank
Filling the Solution Tank:
1. Push the machine to a level water filling station.
2. Turn the propane cylinder service valve clockwise
to close. When the engine has stopped, turn the
key switch to the OFF position.
3. Remove solution tank lid.
4. Fill solution tank with water. Capacity: 9 US gal
(34.1L)
How the Machine Works
This machine is a propane powered hard floor machine. It
has two counter-rotating heads that are bevel gear driven
via an electric clutch and belt. The clutch is controlled by a
switch on the control panel and a safety bail on the handle.
The grinding / polishing heads are designed to
accommodate a variety of 3” diamond disks to grind and
polish concrete, marble, granite, terrazzo, or other stone
floors. The machine can also utilize brushes, pads, and
numerous coating removal heads. Any splash or dust
generated is controlled under the deck with a splash skirt.

LP Fuel Cylinder
This machine uses the 20 lb (9.1 kg) capacity cylinder,
which meets the D.O.T. 4E240 standards. These cylinders
are also listed by UL. In addition, the steel cylinder meets
European TPED specifications and is CE compliant. Filling
should be done ONLY by a qualified propane dealer. A
properly filled cylinder should not exceed 80% of the rated
capacity. Do not overfill the cylinder or use a liquid
withdraw cylinder on the machine. The use of a liquid
withdraw cylinder on a vapor withdraw system could freeze
the regulator and create a fire hazard.
11

Installing the LP Cylinder
1. Before bringing a propane cylinder indoors, always
check it for over-filling.
2. Place the tank on the machine and secure with the
retaining strap. Remove slack by pulling on the
loose end of the strap and secure back to strap.
Connect the fuel hose coupling to the service
valve by turning clockwise. HAND TIGHTEN
ONLY. Make sure coupling is not cross threaded
and check for leakage by noting any propane
odors immediately after cylinder is connected. (It
is sometimes easier to install if the connection to
the service valve is made before strapping the
cylinder in place.)
CAUTION! ONLY USE A VAPOR CYLINDER.
CAUTION! Always open service valve slowly to allow
pressure to equalize in hoses. Opening quickly may cause
the flow check valve to engage, limiting fuel flow.
TO REMOVE THE SAFE-FILL CYLINDER, reverse
procedure. Always connect or change cylinders in a well
ventilated area.
Starting the Machine
1. Check oil and fuel levels.
2. Check and clean engine dust filter.
CAUTION! Never run continuously for more than 1 hour
without cleaning or changing engine dust filter.
3. Check carburetor air filter. Change if necessary.
(See “Scheduled Maintenance”)
4. Turn propane service valve counterclockwise to
open.
CAUTION! Always open service valve slowly to allow
pressure to equalize in hoses. Opening quickly may cause
the flow check valve to engage, limiting fuel flow.
5. With the engine throttle lever in the idle position,
engage the starter by turning the key switch to the
starting position for approximately 5 seconds. If
the engine does not start, release the key switch
for 10 seconds, then try to start again in another 5
seconds.
6. After the engine has started, allow the engine to
warm up for approximately 30 seconds.
WARNING! Catalytic mufflers require a few minutes to
warm up before effectively removing harmful emissions.
Make sure of proper ventilation during this warm-up
period!
Idling and Stopping the Machine
DANGER! Allowing the engine to idle excessively will
increase carbon monoxide emissions!
To stop the engine, close the service valve on the fuel
cylinder by turning it clockwise (the engine will stop when
the fuel in the lines is used up). Once the engine stops,
turn the keyswitch off.

Work Site Transporting
1. Close the valve on the propane cylinder, allow the
engine to stop and turn the machine OFF.
2. Place two of the weight plates on each side of the
control panel. Use the two hooks located just
below the handle pivot knobs on each side.
3. Place the handle in the head change position (see
Handle Adjustment / Position section).
4. Rock the machine back by pushing down on one of
the foot pegs while pulling back on the handle.
5. Push the machine around on the two rear wheels.
Note: Removing all the weights from the front of the
machine makes it easier to transport.
Operating the Machine
1. Inspect the area in which the machine is going to
be used. Remove any loose debris, objects, or
standing studs from the floor.
WARNING! If the counter-rotating heads come in contact
with loose objects or standing studs, they could throw
objects or diamond disks into other objects or people.
2. Place appropriate heads on the machine and
operate according to the application.
3. Add or remove the weights to accommodate the
application.
CAUTION! Keep the machine moving when the heads are
rotating. Failure to do this may result in floor damage.
CAUTION! When using this machine for dry grinding, use
a non-clogging auxiliary vacuum system.
Note: To not comply with any of the CAUTION! statements
could cause the engine to overheat and/or damage the
drive components.
4. When done operating, push the machine to the
desired location. Turn off the LP cylinder service
valve. When the fuel is depleted and the engine
stops, turn the key switch OFF.
5. Remove the LP cylinder and store properly. Refer
to Refueling and Storage of Fuel Cylinders.
Adjusting Deck to be parallel with the Floor
1. Place the machine on the floor where the work is
being performed.
2. Position a level on the floor beside the deck as
shown.
3. Now place the level on the deck, parallel to the
position it was on the floor.
4. Compare the bubble position of the level when it is
on the deck to that of the bubble position when it is
on the floor.
5. Using steps 6 through 8 to adjust the machine so
that the deck will be parallel to the floor.

6. Remove the two pins from the axle pivot holes.
7. Using the axle height adjustment “T” handle, adjust
the height of the axle to the desired position.
Note: Turn the “T” handle clockwise to raise the rear of
the machine and counter-clockwise to lower the rear of the
machine.
8. Replace the two axle pivot pins, placing one on
each side of the axle as close to the bottom of the
axle as possible. This will lock the axle in place.
Note: Locking the axle is done for the first cut on the floor
in order to take off the high spots in the floor. Once the
high spots are gone, the operator should unlock the axle by
moving the pivot pins one hole away from the axle on each
side. This will allow the machine to pivot and follow the
light contours of the floor.
Note: It is recommended to adjust the deck to be parallel
with the floor. Improper adjustment could result in
inefficient operation.
Splash Skirt
1. The skirt should be removed after each use and
cleaned.
2. To remove the skirt, turn the machine off and place
the machine in the head change position.
3. The skirt can be removed by pulling it off of the
deck.
4. To re-install the skirt, start in the back and stretch
the skirt over the perimeter of the deck.
5. When the bottom edge of the skirt is worn, the skirt
can be removed and flipped over to provide a new
wear edge.
6. When the machine is lowered back to the
operating position, push down on the top perimeter
of the skirt so it will conform to the floor.
Note: The skirt can be used for wet or dry applications.
Dust Collection Port
1. The dust collection port located on the left side
of the machine can accommodate 1-1/2” and 2”
diameter hoses.
2. To connect a 1-1/2” diameter hose to the port,
the adapter must be removed. Leave the adapter
for a 2” diameter hose.
3. Use the strap and footman loop located on the side
of the control panel to retain a vacuum hose
against the machine during operation.
Note: Only use a non-clogging auxiliary vacuum for dust
control.
