Fuel System
The fuel system works from vacuum created by the
engine running. Turning the fuel cylinder service valve
ON pressurizes the system for flow to the carburetor
once the engine starts to crank.
Adjusting the Regulator
NOTE: The regulator and carburetor have been
factory preset and should not require any
modification. Only Amano Pioneer Eclipse authorized
personnel, trained and certified in propane systems,
should modify or adjust the system or its setting.
N.F.P.A. 58 8-1.4 states, “In the interest of safety,
each person engaged in installing, repairing, filling, or
otherwise servicing an LP-Gas engine fuel system
shall be properly trained in the necessary
procedures.”
Engine Dust Filter
The engine dust filter should be cleaned each hour
and after each use by shaking out the dust and then
rinsing with mild detergent. Squeeze out the excess
water (do not wring). Allow the filter to air dry.
Failure
to maintain a clean engine filter will cause the
engine to overheat. Also, it may cause the
exhaust emissions to elevate to harmful levels.
Carburetor Air Filter
a. Loosen toggle clamps on each side of the air
cleaner cover.
b. Remove foam pre-cleaner and paper filter
element.
c. Clean foam pre-cleaner.
d. Clean filter seal, making sure no dust is allowed in
the carburetor inlet.
e. Inspect paper element. Replace if dirty, bent or
damaged.
f. Install the clean paper element, pre-cleaner, air
filter cover and reclamp.
NOTE: Failure to service the carburetor air
cleaner may produce excessive carbon
monoxide emissions and cause the SAFE
SENSE system to shut the engine down.
Fuel Hose and Connections
a. Inspection
1) Inspect hoses for abrasions and other signs of
wear; replace all worn or damaged hoses.
2) Check for gas leaks by spreading soapy water
solution around all the connections while the
service valve is turned ON and the fuel system
is pressurized.
b. Fixing Leaking Joints
1) Uncouple bad joint and clean it. Then apply
pipe sealing compound (Loc-Tite Pipe Sealant
with Teflon or equivalent) to the clean joint.
2) Recouple the joint finger tight plus 1/2 turn.
3)
Recheck for leaks using soapy water
solution. Watch for bubbles at the joint with
the fuel cylinder service valve turned on
and the fuel system pressurized.
Engine Maintenance
Cooling Fin Maintenance
a. Remove the blower housing and other cooling
shrouds.
b. Clean the cooling fins as necessary using
compressed air or pressure washer.

Changing Oil
a. Run engine for 5 minutes to warm oil, then stop the

deck to maintain an upright, level position.
c. Remove the propane cylinder to access oil drain
hose.
d. Remove the oil drain hose from the retaining clip,
and remove the plug from the end of the hose.
e. Place drain pan at back of machine and direct oil

turn counterclockwise to open valve.
g. Allow oil to drain completely.
h. If changing oil filter, place an absorbent material
under the filter to catch spillage. Remove filter by
turning counterclockwise. Discard old oil filter
according to local regulations. Clean any oil
spillage from machine, apply a small amount of
clean oil to new oil filter seal, install new filter
turning clockwise and hand tighten.
