Spark Plug Inspection and Replacement
1. Turn off LP cylinder and remove it.
2. Pull spark plug cap off of spark plug.
3. Remove spark plug by turning counter-clockwise
and inspect it.
Note: If the plug is oily or has carbon build up on it, clean
the plug using a high flash-point solvent and a wire brush
or other suitable tool.
Note: If the spark plug electrodes are corroded or
damaged, or if the insulator is cracked, replace the plug.
Use Only Amano Pioneer Eclipse part # KA920702112.
Do not use any other spark plug!
4. Measure the gap with a wire-type thickness
gauge. The correct gap is .025 in (.635 mm). If
the gap is incorrect, carefully bend the side
electrode with a suitable tool to obtain the correct
gap
A: Insulator
B: Center Electrode
C: Plug Gap
D: Side Electrode
Air Filter Inspection and Replacement
1. Push machine to level surface.
2. Turn off LP cylinder and remove it.
3. Turn the two knobs 1/4 turn counter-clockwise and
remove the filter cover.
4. Loosen clamp that retains filter and remove the air
filter.
CAUTION! Do not wash the air cleaner filters. Do not oil
the air filters. Do not use pressurized air to clean the air
filters.
5. Inspect both primary and secondary air filters. If
necessary, clean primary filter by lightly tapping
and wipe seal ends with a clean cloth. If primary
filter cannot be cleaned, is bent, or damaged, it
must be replaced. (Amano Pioneer Eclipse part
# KA110137049). If secondary filter is dirty, do not
attempt to clean it. Replace it with a new filter
(Amano Pioneer Eclipse part #KA110137046).
6. Check the intake hose for cracks or damage.
7. Install filters and replace cover.
Inspect Fuel Hose and Connections
1. Push machine to level surface.
2. Turn off LP cylinder and remove it.
3. Inspect hoses for abrasions and other signs of
wear. Replace all worn or damaged hoses.
4. Check for gas leaks by spreading a soapy water
solution around all connections while the LP
cylinder is reconnected and the service valve is
turned ON.
5. If a leak is detected, turn off the LP cylinder. If the
leak is in a hose, replace it. If the leak is at a
fitting, loosen and clean it. Apply pipe-sealing
compound and re-tighten it.
6. Recheck for leaks using a soapy water solution. If
leaks persist at fittings, replace them and recheck
with a soapy water solution once more.
Engine Dust Filter
1. The engine dust filter should be cleaned each hour
and after each use by shaking out the dust and
then rinsing with mild detergent. The filter can
also be vacuumed with a wet-dry vacuum.
2. Squeeze out the excess water (do not wring).
3. Allow the filter to air dry.
Note: 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. If necessary,
replace with (APEC part number: MP035200).
